WEBVTT 00:00:00.000 --> 00:00:02.799 Welcome back to the Deep Dive. This is the show 00:00:02.799 --> 00:00:05.339 where we take a massive stack of research articles, 00:00:05.559 --> 00:00:08.480 expert notes, historical findings, and we try 00:00:08.480 --> 00:00:11.019 to distill it all down to the essential, fascinating, 00:00:11.259 --> 00:00:14.460 and sometimes, frankly, alarming truths you need 00:00:14.460 --> 00:00:17.460 to know. That's right. Today, we are diving deep 00:00:17.460 --> 00:00:20.280 into a fundamental instrument of homeownership 00:00:20.280 --> 00:00:22.780 and finance. We're talking about the adjustable 00:00:22.780 --> 00:00:26.399 rate mortgage, or ARM. And if you live outside 00:00:26.399 --> 00:00:28.280 the United States, you probably know this as 00:00:28.280 --> 00:00:30.140 something else, maybe a variable rate mortgage 00:00:30.140 --> 00:00:34.200 or a tracker mortgage. But the the core idea 00:00:34.200 --> 00:00:36.399 is exactly the same everywhere. And what is that 00:00:36.399 --> 00:00:39.859 core idea? It's a mortgage loan where the interest 00:00:39.859 --> 00:00:42.159 rate and because of that, the monthly payment 00:00:42.159 --> 00:00:44.579 you have to make is periodically adjusted. It 00:00:44.579 --> 00:00:46.280 changes throughout the life of the loan. OK, 00:00:46.320 --> 00:00:48.020 let's unpack that right away, because the language 00:00:48.020 --> 00:00:50.219 around mortgages can be so confusing. We're talking 00:00:50.219 --> 00:00:52.159 about the rate itself changing, not just say. 00:00:52.539 --> 00:00:54.840 The payment schedule. Precisely. The whole engine 00:00:54.840 --> 00:00:57.340 here is that dynamic interest rate. It's tied 00:00:57.340 --> 00:01:00.320 to some external verifiable financial indicator, 00:01:00.600 --> 00:01:04.400 an index. An index. Yeah, an index that reflects 00:01:04.400 --> 00:01:06.939 what it costs to borrow money on the big credit 00:01:06.939 --> 00:01:09.480 markets. This is completely different from something 00:01:09.480 --> 00:01:12.459 like a graduated payment mortgage where the rate 00:01:12.459 --> 00:01:14.760 is fixed for 30 years, but your payment just 00:01:14.760 --> 00:01:17.500 starts low and goes up on a set schedule. So 00:01:17.500 --> 00:01:21.180 in an ARM, the payment is changing because the... 00:01:22.120 --> 00:01:24.340 the underlying cost of money is actually moving. 00:01:24.400 --> 00:01:27.099 That's it. So if the rate itself is dynamic, 00:01:27.500 --> 00:01:29.540 we're really talking about an instrument that's 00:01:29.540 --> 00:01:32.260 designed to do one main thing for the lender. 00:01:32.420 --> 00:01:34.799 Oh, absolutely. It's about risk. It's about transferring 00:01:34.799 --> 00:01:38.260 risk. 100%. ARMs are built, I mean, first and 00:01:38.260 --> 00:01:40.799 foremost, to shift that big piece of interest 00:01:40.799 --> 00:01:43.840 rate risk. You know, the chance that market rates 00:01:43.840 --> 00:01:46.379 will just shoot up from the lender's books directly 00:01:46.379 --> 00:01:48.540 onto you, the borrower. But there has to be a 00:01:48.540 --> 00:01:50.459 tradeoff, right? You don't just take on all that 00:01:50.459 --> 00:01:52.840 risk for nothing. That's the hook. That's the 00:01:52.840 --> 00:01:55.599 key benefit. Because the lender is now shielded 00:01:55.599 --> 00:01:58.140 from that future volatility, they can afford 00:01:58.140 --> 00:02:01.640 to offer you a lower initial interest rate. And 00:02:01.640 --> 00:02:03.420 that's the part that gets everyone's attention. 00:02:04.099 --> 00:02:07.379 That low starting number. It's seductive. It 00:02:07.379 --> 00:02:10.400 is the primary incentive. You see that low starting 00:02:10.400 --> 00:02:12.659 rate. You compare it to the fixed rate loan, 00:02:12.860 --> 00:02:15.780 and it just lowers that initial hurdle to buying 00:02:15.780 --> 00:02:18.259 a home. You know, a lot of finance experts have 00:02:18.259 --> 00:02:20.259 even suggested that unless interest rates are 00:02:20.259 --> 00:02:23.400 already at rock bottom, you, the borrower, should 00:02:23.400 --> 00:02:26.580 probably prefer an ARM. That sounds completely 00:02:26.580 --> 00:02:28.860 backwards. You're saying prefer the riskier product. 00:02:29.139 --> 00:02:31.080 Well, even with the risk, that lower initial 00:02:31.080 --> 00:02:34.360 cost lets you save more or invest more in those 00:02:34.360 --> 00:02:36.180 first few years of the loan. It's a fascinating 00:02:36.180 --> 00:02:38.560 piece of counterintuitive advice. OK, so our 00:02:38.560 --> 00:02:41.400 mission today is to go way beyond that low teaser 00:02:41.400 --> 00:02:44.500 rate. We need to dissect the nine, you said nine 00:02:44.500 --> 00:02:47.060 core components of an ARM. That's right. We have 00:02:47.060 --> 00:02:49.719 to understand the global variance that. I mean, 00:02:49.740 --> 00:02:52.259 let's be honest, led to financial crises. And 00:02:52.259 --> 00:02:54.319 then we have to confront this really surprising 00:02:54.319 --> 00:02:57.979 history of systematic calculation errors and 00:02:57.979 --> 00:03:00.120 financial scandals that are tied to these contracts. 00:03:00.340 --> 00:03:02.860 This whole thing is like a math puzzle. And you, 00:03:02.979 --> 00:03:06.020 the borrower, are the one holding the bill. OK, 00:03:06.120 --> 00:03:09.210 let's start with the. the basic anatomy of an 00:03:09.210 --> 00:03:11.409 ARM. I mean, we often just think of it as a rate 00:03:11.409 --> 00:03:13.789 that moves, but the source material says there 00:03:13.789 --> 00:03:15.650 are nine core features that come together to 00:03:15.650 --> 00:03:18.530 make this thing work. Let's start with the essential 00:03:18.530 --> 00:03:22.370 three, the index, the margin, and the initial 00:03:22.370 --> 00:03:24.189 rate. These three are absolutely foundational. 00:03:24.449 --> 00:03:26.250 So number one is the initial interest rate. That's 00:03:26.250 --> 00:03:28.030 just the rate you pay when you first sign the 00:03:28.030 --> 00:03:30.090 papers and close the loan. Simple enough. Right, 00:03:30.129 --> 00:03:32.849 the starting line. But that rate gets replaced 00:03:32.849 --> 00:03:35.189 pretty quickly by the real engine of this whole 00:03:35.189 --> 00:03:37.930 thing, which is feature number three. The index 00:03:37.930 --> 00:03:41.050 rate. The index is the fundamental driver of 00:03:41.050 --> 00:03:44.090 your cost. It's that external rate the ARM tracks. 00:03:44.389 --> 00:03:46.650 It reflects the cost of borrowing money for the 00:03:46.650 --> 00:03:49.229 banks themselves. And it's moving all the time. 00:03:49.289 --> 00:03:51.729 Your rate is literally feathered to it. Which 00:03:51.729 --> 00:03:55.189 brings us to number four, the margin. Now, this 00:03:55.189 --> 00:03:57.590 sounds like the lender's profit. It's their profit 00:03:57.590 --> 00:04:00.250 and their insurance. Exactly. The margin is a 00:04:00.250 --> 00:04:02.330 fixed number of percentage points, let's say 00:04:02.330 --> 00:04:05.909 2%, that the lender adds on top of the index 00:04:05.909 --> 00:04:10.379 rate. Index rate plus the margin equals the actual 00:04:10.379 --> 00:04:12.900 rate I pay. That's your fully indexed rate. And 00:04:12.900 --> 00:04:15.180 what's crucial here is that the margin, that 00:04:15.180 --> 00:04:17.800 2%, is written into your loan contract and it 00:04:17.800 --> 00:04:19.879 is fixed for the entire 30 -year life of the 00:04:19.879 --> 00:04:22.399 loan. It never changes. So the bank has guaranteed 00:04:22.399 --> 00:04:24.079 their cut no matter what. It guarantees them 00:04:24.079 --> 00:04:26.160 a consistent profit spread, whether the market 00:04:26.160 --> 00:04:28.720 index is high or low. So if the index is, say, 00:04:28.819 --> 00:04:32.560 4 % and the margin is 2%, my current rate is 00:04:32.560 --> 00:04:36.639 6%. If that index shoots up to 6%, my new rate 00:04:36.639 --> 00:04:41.199 is 8%. But that 2 % for the lender? That's always 00:04:41.199 --> 00:04:43.379 there. It's the bedrock of the contract. That 00:04:43.379 --> 00:04:45.800 stability for the lender is the entire reason 00:04:45.800 --> 00:04:48.740 the ARM exists. Okay. Now let's look at the other 00:04:48.740 --> 00:04:50.439 features, the ones that are less about the math 00:04:50.439 --> 00:04:52.579 and more about, I guess, controlling the risk 00:04:52.579 --> 00:04:54.519 and the flow of payments. You mentioned feature 00:04:54.519 --> 00:04:56.819 number two, the adjustment period. Right. And 00:04:56.819 --> 00:04:58.720 this really sets the rhythm for your risk exposure 00:04:58.720 --> 00:05:01.360 as a borrower. How so? It's the set amount of 00:05:01.360 --> 00:05:03.319 time that the interest rate stays completely 00:05:03.319 --> 00:05:05.360 frozen before the lender is allowed to reset 00:05:05.360 --> 00:05:07.620 it, you know, based on the new index value. It 00:05:07.620 --> 00:05:09.920 might be every six months. It might be once a 00:05:09.920 --> 00:05:12.220 year. or for some products only every five years. 00:05:12.360 --> 00:05:15.839 But that date on the calendar, that's when your 00:05:15.839 --> 00:05:17.920 risk becomes real. Then there's feature number 00:05:17.920 --> 00:05:20.259 five. And I think you could argue this is the 00:05:20.259 --> 00:05:22.420 most important one for protecting the borrower. 00:05:23.180 --> 00:05:26.029 Interstreet caps. These are the guardrails. They 00:05:26.029 --> 00:05:28.430 are limitations on how much your rate or your 00:05:28.430 --> 00:05:31.149 payment can change. They're designed to prevent 00:05:31.149 --> 00:05:33.790 the rate from rising too much in one go or too 00:05:33.790 --> 00:05:36.050 high over the whole life of the loan. We're going 00:05:36.050 --> 00:05:38.629 to have to spend a lot of time on caps because 00:05:38.629 --> 00:05:40.750 they're really the only defense a borrower has. 00:05:40.910 --> 00:05:43.189 OK, then we have the features that, let's be 00:05:43.189 --> 00:05:45.509 honest, can be used to hide the true cost of 00:05:45.509 --> 00:05:49.220 the loan. Number six. Initial discounts. The 00:05:49.220 --> 00:05:51.980 famous teaser rates. This is when the lender 00:05:51.980 --> 00:05:53.980 offers a promotional starting rate that's actually 00:05:53.980 --> 00:05:57.319 below the real fully indexed rate. Below the 00:05:57.319 --> 00:06:00.720 index plus the margin. Like a sale price. Exactly. 00:06:00.879 --> 00:06:03.660 They might offer you a 3 % starting rate when 00:06:03.660 --> 00:06:07.459 the actual calculated rate is 5 .5%. It's a really 00:06:07.459 --> 00:06:09.300 powerful incentive. It makes your first payment 00:06:09.300 --> 00:06:12.019 super low, but it guarantees you're going to 00:06:12.019 --> 00:06:14.259 get a sharp jump at that very first adjustment. 00:06:14.379 --> 00:06:16.259 Which leads us straight to number seven, the 00:06:16.259 --> 00:06:20.319 most terrifying feature for most people. Negative 00:06:20.319 --> 00:06:24.199 amortization. Neg -am. This is a really high 00:06:24.199 --> 00:06:27.420 risk feature. It happens when the monthly payment 00:06:27.420 --> 00:06:29.680 you choose to make is actually less than the 00:06:29.680 --> 00:06:32.220 interest that's due for that month. So where 00:06:32.220 --> 00:06:34.480 does the unpaid interest go? It gets added right 00:06:34.480 --> 00:06:36.540 back onto your principal loan balance. You are 00:06:36.540 --> 00:06:39.779 literally borrowing more money to pay the interest 00:06:39.779 --> 00:06:42.100 you already owe. So your debt is growing every 00:06:42.100 --> 00:06:43.839 month. Even though you're making payments, you're 00:06:43.839 --> 00:06:46.220 losing equity. That's exactly what's happening. 00:06:46.339 --> 00:06:48.519 We absolutely have to dig into this when we talk 00:06:48.519 --> 00:06:52.490 about the more wild types of air arms. on. For 00:06:52.490 --> 00:06:54.829 sure. So the last two features seem more procedural. 00:06:55.029 --> 00:06:57.449 Number eight is conversion. Yeah, this is like 00:06:57.449 --> 00:06:59.329 a potential escape hatch. It's a clause that 00:06:59.329 --> 00:07:01.550 might let you convert your ARM into a fixed rate 00:07:01.550 --> 00:07:03.610 mortgage at certain points during the loan, usually 00:07:03.610 --> 00:07:07.449 for a small fee. And finally, number nine, prepayment 00:07:07.449 --> 00:07:09.990 terms. Everyone needs to be really careful here. 00:07:10.449 --> 00:07:13.649 Some ARMs, especially the ones with those deep 00:07:13.649 --> 00:07:16.889 teaser rates, have penalties if you pay the loan 00:07:16.889 --> 00:07:19.910 off early. Like if you refinance. Exactly. If 00:07:19.910 --> 00:07:22.790 you refinance within the first few years, you 00:07:22.790 --> 00:07:24.829 have to check your contract to see if there's 00:07:24.829 --> 00:07:27.009 a prepayment penalty and, you know, how long 00:07:27.009 --> 00:07:29.730 it lasts. Our sources say these are sometimes 00:07:29.730 --> 00:07:32.610 negotiable, but you have to check before you 00:07:32.610 --> 00:07:35.670 sign. That breakdown really clarifies just how 00:07:35.670 --> 00:07:37.769 many moving parts there are. OK, let's drill 00:07:37.769 --> 00:07:40.050 down into the index rates themselves. You said 00:07:40.050 --> 00:07:42.110 these external numbers are the engine that drives 00:07:42.110 --> 00:07:44.329 the whole thing. The number of different indices 00:07:44.329 --> 00:07:48.079 used just seems. Well, they do fall into a few 00:07:48.079 --> 00:07:50.199 distinct categories. In the U .S., for instance, 00:07:50.319 --> 00:07:51.860 you'll see indices that are tied to government 00:07:51.860 --> 00:07:54.220 debt. Like what? Things like the Constant Maturity 00:07:54.220 --> 00:07:58.300 Treasury or CMT Index or the 12 -Month Treasury 00:07:58.300 --> 00:08:01.720 Average Index, the MTA. These are pretty transparent 00:08:01.720 --> 00:08:03.540 because they're based on the government's own 00:08:03.540 --> 00:08:06.120 cost of borrowing. Okay. And then you have indices 00:08:06.120 --> 00:08:08.199 that reflect what it costs banks to get money. 00:08:08.379 --> 00:08:12.019 Right. The really famous one was the London Interbank 00:08:12.019 --> 00:08:15.879 Offered Rate LIBOR. For decades, it was the dominant 00:08:15.879 --> 00:08:18.579 global index, but it's being phased out now after 00:08:18.579 --> 00:08:20.800 all those manipulation scandals. You'll also 00:08:20.800 --> 00:08:23.480 see things like the 11th District Cost of Funds 00:08:23.480 --> 00:08:26.600 Index or COFAFI, which is based on the average 00:08:26.600 --> 00:08:29.600 cost of funds for a group of savings and loans 00:08:29.600 --> 00:08:31.680 out on the West Coast. And what about internationally? 00:08:32.269 --> 00:08:34.210 Oh, you see all sorts. There's the Australian 00:08:34.210 --> 00:08:37.649 Bank bill swap rate, the BBSW. In some cases, 00:08:37.669 --> 00:08:39.370 believe it or not, they even use the General 00:08:39.370 --> 00:08:42.450 Consumer Price Index, the CPI, which links your 00:08:42.450 --> 00:08:45.529 mortgage rate directly to inflation. That variety 00:08:45.529 --> 00:08:47.610 stands out. I mean, why would a lender pick one 00:08:47.610 --> 00:08:50.029 index over another? Is it just random? No, it's 00:08:50.029 --> 00:08:52.149 very strategic. A lender that picks an index 00:08:52.149 --> 00:08:54.529 that closely tracks their own internal cost of 00:08:54.529 --> 00:08:57.450 funds, like the CCOFI index, is making sure there's 00:08:57.450 --> 00:08:59.450 a really tight match between their expenses and 00:08:59.450 --> 00:09:01.149 their income. So if their funding costs go up, 00:09:01.389 --> 00:09:03.330 Their mortgage income goes up almost at the same 00:09:03.330 --> 00:09:06.669 time. On the other hand, if you, the borrower, 00:09:06.710 --> 00:09:09.830 pick an ARM that's tied to a less volatile index 00:09:09.830 --> 00:09:13.049 like that 12 month Treasury average, you might 00:09:13.049 --> 00:09:16.090 get smoother adjustments. But the lender is taking 00:09:16.090 --> 00:09:18.750 on a little more risk that the index won't perfectly 00:09:18.750 --> 00:09:21.210 match what they're paying for their money. So 00:09:21.210 --> 00:09:24.009 if a lender uses its own cost of funds as the 00:09:24.009 --> 00:09:27.129 index, that's the ultimate risk avoidance play 00:09:27.129 --> 00:09:29.700 for them. They're making absolutely sure their 00:09:29.700 --> 00:09:32.179 margin is safe no matter what happens. Okay. 00:09:32.240 --> 00:09:34.419 So if we connect this all back to the complexity 00:09:34.419 --> 00:09:36.820 of the ARM, what's really fascinating is that 00:09:36.820 --> 00:09:39.399 the index isn't always applied in that simple 00:09:39.399 --> 00:09:41.919 way we described. Right. There are actually three 00:09:41.919 --> 00:09:44.419 different adjustment mechanisms that you'll find 00:09:44.419 --> 00:09:47.179 in loan contracts. And understanding which one 00:09:47.179 --> 00:09:49.740 governs your loan is absolutely critical if you 00:09:49.740 --> 00:09:51.500 want to predict your future payments. I think 00:09:51.500 --> 00:09:53.700 most people, myself included, always assumed 00:09:53.700 --> 00:09:56.759 it was just index plus margin. But you're saying 00:09:56.759 --> 00:09:58.460 that's just one way of doing it. That's only 00:09:58.460 --> 00:10:00.480 one of the mechanisms. Let's start with the simplest 00:10:00.480 --> 00:10:03.039 one. Mechanism one, the directly applied index. 00:10:03.259 --> 00:10:05.320 How does that one work? In this structure, which 00:10:05.320 --> 00:10:07.840 is pretty rare, the interest rate on your loan 00:10:07.840 --> 00:10:10.539 is exactly equal to whatever the current value 00:10:10.539 --> 00:10:13.899 of the index is. If the index is 5%, your rate 00:10:13.899 --> 00:10:16.899 is 5%. It mirrors the index perfectly. So there's 00:10:16.899 --> 00:10:19.730 no margin. Essentially, no. The source material 00:10:19.730 --> 00:10:21.909 says you really only see this when the index 00:10:21.909 --> 00:10:24.570 itself is a contract rate index, one that's meant 00:10:24.570 --> 00:10:26.950 to reflect an average lending rate. It's super 00:10:26.950 --> 00:10:29.149 transparent, but, you know, very few lenders 00:10:29.149 --> 00:10:31.129 will do it because they could lose money if their 00:10:31.129 --> 00:10:33.370 own cost of funds goes higher than the index. 00:10:33.529 --> 00:10:36.129 OK, that makes sense. Which brings us to mechanism 00:10:36.129 --> 00:10:38.490 two, which you said is the most common one, the 00:10:38.490 --> 00:10:40.850 rate plus margin basis. This is the one we've 00:10:40.850 --> 00:10:42.850 been talking about. The interest rate is the 00:10:42.850 --> 00:10:45.370 current value of the index, plus that fixed margin 00:10:45.370 --> 00:10:47.730 you agreed on when you signed the loan. Let's 00:10:47.730 --> 00:10:49.850 use an example. Okay, let's say the index is 00:10:49.850 --> 00:10:53.230 the CMT, and it's at 4%. Your agreed upon margin 00:10:53.230 --> 00:10:56.230 is 2%. For this period, your interest rate is 00:10:56.230 --> 00:11:00.110 6%. Simple. And if the CMT goes up to 5 % at 00:11:00.110 --> 00:11:03.029 the next adjustment? Your rate becomes 7%. The 00:11:03.029 --> 00:11:05.529 calculation is direct. It's clear. It's predictable. 00:11:05.870 --> 00:11:08.549 You, the borrower, know exactly what your cost 00:11:08.549 --> 00:11:11.190 will be just by looking at the index. Okay, now 00:11:11.190 --> 00:11:14.129 for the tricky one. Mechanism three, the movement 00:11:14.129 --> 00:11:16.750 basis. This one sounds like it introduces a lot 00:11:16.750 --> 00:11:20.029 of opacity. It really does. In this structure, 00:11:20.149 --> 00:11:22.549 your mortgage starts at some agreed upon initial 00:11:22.549 --> 00:11:25.509 rate, which may or may not be the true fully 00:11:25.509 --> 00:11:28.580 indexed rate. But here's the key. The adjustments 00:11:28.580 --> 00:11:31.279 that follow are tied only to the movement of 00:11:31.279 --> 00:11:33.960 the index. Not by adding the margin to the current 00:11:33.960 --> 00:11:36.179 index. Exactly. It's not based on the current 00:11:36.179 --> 00:11:38.460 value of the index plus the margin. Can you give 00:11:38.460 --> 00:11:40.139 us an illustration of that? Use the same numbers? 00:11:40.299 --> 00:11:43.720 Sure. So index is 4%, margin is 2%. With the 00:11:43.720 --> 00:11:46.159 standard rate plus margin model, your start rate 00:11:46.159 --> 00:11:49.789 is the fully indexed rate. 6%. Right. Now, with 00:11:49.789 --> 00:11:52.029 the movement basis, the lender might offer you 00:11:52.029 --> 00:11:54.389 a slightly different starting rate, maybe 5 .5%. 00:11:54.389 --> 00:11:57.129 Then at the first adjustment, the index has gone 00:11:57.129 --> 00:12:00.490 up from 4 % to 5%. That's a 1 % upward movement. 00:12:00.690 --> 00:12:03.129 So how do they calculate the new rate? The new 00:12:03.129 --> 00:12:05.149 interest rate will be your initial rate, the 00:12:05.149 --> 00:12:08.230 5 .5%, plus the movement of the index, that 1%. 00:12:08.230 --> 00:12:11.950 So your new rate is 6 .5%. Ah, okay. I see the 00:12:11.950 --> 00:12:15.129 difference. It's subtle, but it's huge. In the 00:12:15.129 --> 00:12:17.419 first method, The new rate would be the current 00:12:17.419 --> 00:12:21.139 index, 5%, plus the margin, 2%, which is 7%. 00:12:21.139 --> 00:12:23.279 Right. But in this method, it's the starting 00:12:23.279 --> 00:12:26.940 rate, 5 .5%, plus the change in the index, 1%, 00:12:26.940 --> 00:12:30.659 which is only 6 .5%. Exactly. The final rate 00:12:30.659 --> 00:12:32.980 under the movement basis is way less predictable 00:12:32.980 --> 00:12:34.960 because it's anchored to that initial starting 00:12:34.960 --> 00:12:36.580 rate, which could have been set arbitrarily. 00:12:37.500 --> 00:12:39.519 You, the borrower, have to track not just the 00:12:39.519 --> 00:12:41.379 current index value, but what the index was at 00:12:41.379 --> 00:12:43.600 the last adjustment to. And that complexity, 00:12:43.740 --> 00:12:45.620 I can see how that's where the errors start to 00:12:45.620 --> 00:12:47.860 creep in. This is where operational errors thrive. 00:12:48.200 --> 00:12:50.879 That right there proves why these are so much 00:12:50.879 --> 00:12:53.399 more complex than a fixed rate loan. When the 00:12:53.399 --> 00:12:56.299 basic math has three different versions, the 00:12:56.299 --> 00:12:59.200 chances for a simple human mistake or a computer 00:12:59.200 --> 00:13:02.799 glitch just multiply. And with that kind of complexity, 00:13:02.860 --> 00:13:05.639 you absolutely need some serious protection against 00:13:05.639 --> 00:13:08.100 the rate hikes. This is where it gets really 00:13:08.100 --> 00:13:09.940 interesting for me, because the central fear 00:13:09.940 --> 00:13:13.679 for any ARM borrower is payment shock. You know, 00:13:13.720 --> 00:13:15.919 that sudden huge jump in your monthly payment 00:13:15.919 --> 00:13:19.860 when the rate resets. If the index is the engine 00:13:19.860 --> 00:13:22.019 of risk, then the caps have to be the breaks. 00:13:22.259 --> 00:13:24.860 How are those breaks actually designed? The caps 00:13:24.860 --> 00:13:27.220 are absolutely the critical structural limits 00:13:27.220 --> 00:13:29.360 on how much things can change. Without them, 00:13:29.419 --> 00:13:31.720 the financial risk would be, well, astronomical. 00:13:31.759 --> 00:13:33.960 They usually work across three different categories, 00:13:34.200 --> 00:13:36.779 creating a kind of layered defense for you. Okay. 00:13:37.120 --> 00:13:39.259 What are those three layers of protection? So 00:13:39.259 --> 00:13:41.500 first, there's the frequency cap. This just limits 00:13:41.500 --> 00:13:43.980 how often the rate can change. If your loan adjusts 00:13:43.980 --> 00:13:45.919 annually, the frequency cap means they can't 00:13:45.919 --> 00:13:47.539 suddenly start changing it every six months. 00:13:47.759 --> 00:13:50.559 Yeah. And second? The periodic change cap. This 00:13:50.559 --> 00:13:53.480 one sets the maximum amount the rate is allowed 00:13:53.480 --> 00:13:56.000 to go up or down in any single adjustment period. 00:13:56.220 --> 00:13:59.620 A very common one is a 1 % or maybe a 2 % periodic 00:13:59.620 --> 00:14:03.100 cap. And third, the ultimate ceiling, the life 00:14:03.100 --> 00:14:05.779 cap. This is the lifetime cap, and it sets the 00:14:05.779 --> 00:14:09.620 absolute highest your rate can ever go. For most 00:14:09.620 --> 00:14:12.480 primary mortgages, this cap is set at maybe 5 00:14:12.480 --> 00:14:15.679 % or 6 % above your original starting rate. So 00:14:15.679 --> 00:14:18.059 if you start at 4 % and you have a 6 % life cap, 00:14:18.240 --> 00:14:21.399 your rate can never, ever go above 10%. Let's 00:14:21.399 --> 00:14:23.139 dig into how those caps are structured, because 00:14:23.139 --> 00:14:24.700 it seems like they're not always the same. It 00:14:24.700 --> 00:14:26.340 sounds like the lender gets a bigger bite at 00:14:26.340 --> 00:14:28.799 the apple early on. That is the key insight. 00:14:29.309 --> 00:14:31.450 The initial adjustment rate cap is often treated 00:14:31.450 --> 00:14:33.649 differently from all the ones that follow. This 00:14:33.649 --> 00:14:36.370 first cap only applies the very first time your 00:14:36.370 --> 00:14:38.870 rate resets, right after that introductory fixed 00:14:38.870 --> 00:14:40.929 period ends. And the sources say this initial 00:14:40.929 --> 00:14:43.429 cap is usually more aggressive. Why would that 00:14:43.429 --> 00:14:45.980 be? Well, the lender needs to get your loan from 00:14:45.980 --> 00:14:48.539 that artificially low teaser rate up to the real 00:14:48.539 --> 00:14:51.159 fully indexed rate as quickly as possible. So 00:14:51.159 --> 00:14:53.200 if you have a short introductory term, maybe 00:14:53.200 --> 00:14:55.299 one to three years fixed, the initial cap might 00:14:55.299 --> 00:14:57.960 be 2 % or 3%. But if you have a longer fixed 00:14:57.960 --> 00:15:00.700 term, like a five or seven year ARM. Then the 00:15:00.700 --> 00:15:03.460 lender might set a much larger initial cap, maybe 00:15:03.460 --> 00:15:06.879 5 % or even 6 % on that first adjustment. They 00:15:06.879 --> 00:15:08.720 have to play catch up for all the years they've 00:15:08.720 --> 00:15:10.659 been charging you less than the market rate. 00:15:10.799 --> 00:15:13.000 So the longer you're safe in that fixed period. 00:15:13.360 --> 00:15:15.080 the harder that first adjustment is going to 00:15:15.080 --> 00:15:17.539 hit you, even with a cap. Precisely. After that 00:15:17.539 --> 00:15:19.980 first big jump, all the later rate changes are 00:15:19.980 --> 00:15:22.360 limited by the much tighter rate adjustment cap. 00:15:22.480 --> 00:15:25.179 That's usually the 1 % or 2 % maximum increase 00:15:25.179 --> 00:15:28.580 per period. The idea is to smooth out the rest 00:15:28.580 --> 00:15:31.279 of the volatility for you. This structure is 00:15:31.279 --> 00:15:33.480 why the industry came up with that number shorthand. 00:15:33.580 --> 00:15:35.960 Let's break down the 225 structure. Right. That 00:15:35.960 --> 00:15:38.179 shorthand is essential for a quick risk check. 00:15:38.320 --> 00:15:41.759 A 225 structure means, first, a 2 % cap on the 00:15:41.759 --> 00:15:43.779 maximum increase for your initial adjustment. 00:15:44.059 --> 00:15:47.539 Second, another 2 % cap on the maximum increase 00:15:47.539 --> 00:15:50.100 for all subsequent adjustments. And finally, 00:15:50.179 --> 00:15:53.200 a 5 % cap on the maximum increase over the entire 00:15:53.200 --> 00:15:55.840 life of the loan measured from your initial start 00:15:55.840 --> 00:15:58.049 rate. Let's walk through an example of how those 00:15:58.049 --> 00:16:00.009 caps work together. Let's say you start with 00:16:00.009 --> 00:16:03.509 a 3 % rate, but the market has moved so much 00:16:03.509 --> 00:16:06.710 that your real fully indexed rate should now 00:16:06.710 --> 00:16:10.090 be 8%. That's a 5 % jump. Right. At that initial 00:16:10.090 --> 00:16:12.629 investment, that 2 % periodic cap kicks in. So 00:16:12.629 --> 00:16:15.129 you're protected from the full 5 % market increase. 00:16:15.289 --> 00:16:18.350 Your rate only goes up from 3 % to 5%. A 2 % 00:16:18.350 --> 00:16:20.509 increase. But what happens to the other 3 % the 00:16:20.509 --> 00:16:23.139 bank wants to charge me? That extra 3 % is basically 00:16:23.139 --> 00:16:26.299 banked or carried over to future adjustment periods. 00:16:26.659 --> 00:16:28.539 So at the second adjustment, if the market rate 00:16:28.539 --> 00:16:31.259 is still at 8%, the lender can use that banked 00:16:31.259 --> 00:16:33.259 increase, but they're still limited by that subsequent 00:16:33.259 --> 00:16:35.879 2 % cap. Exactly. Even though the market still 00:16:35.879 --> 00:16:38.279 justifies an 8 % rate, they can only raise your 00:16:38.279 --> 00:16:40.799 rate by another 2%, taking you from 5 % up to 00:16:40.799 --> 00:16:43.159 7%. They're still not at the fully indexed rate, 00:16:43.220 --> 00:16:44.799 but they're following the rules of the cap. And 00:16:44.799 --> 00:16:46.940 that just repeats until my rate eventually hits 00:16:46.940 --> 00:16:49.820 that 8 % market rate or... until I hit my ultimate 00:16:49.820 --> 00:16:52.259 ceiling, the life cap. Right. In our example, 00:16:52.320 --> 00:16:54.759 the life cap was 5%, so your rate could never 00:16:54.759 --> 00:16:58.179 go above 8 % anyway. That's the 3 % start rate 00:16:58.179 --> 00:17:01.340 plus the 5 % life cap. That interaction between 00:17:01.340 --> 00:17:03.240 the caps is what's supposed to protect you from 00:17:03.240 --> 00:17:06.440 that massive one -time payment shock. It spreads 00:17:06.440 --> 00:17:08.700 the pain out. Now, we have to contrast this whole 00:17:08.700 --> 00:17:11.259 controlled system with the big exception from 00:17:11.259 --> 00:17:13.670 the source material. home equity lines of credit, 00:17:13.809 --> 00:17:16.769 or ELOXs, this really shows how much protection 00:17:16.769 --> 00:17:19.740 those standard ARM caps actually provide. Oh, 00:17:19.819 --> 00:17:22.119 ELOCs are a completely different animal. They're 00:17:22.119 --> 00:17:24.420 usually used for second mortgages or for revolving 00:17:24.420 --> 00:17:27.900 credit. A standard ARM has those rigid 1 -2 % 00:17:27.900 --> 00:17:30.960 periodic caps and the tight 5 -6 % life caps. 00:17:31.180 --> 00:17:33.319 An ELOC, though. What do they have? They often 00:17:33.319 --> 00:17:35.579 have no periodic caps at all. Their only limit 00:17:35.579 --> 00:17:37.539 is usually whatever the maximum interest rate 00:17:37.539 --> 00:17:39.519 is allowed by state law. And that could be as 00:17:39.519 --> 00:17:42.480 high as 18 % in a state like Florida. 18%. That 00:17:42.480 --> 00:17:45.220 is a completely different universe of risk. And 00:17:45.220 --> 00:17:48.279 their index is different, too. ELOCs are usually 00:17:48.279 --> 00:17:50.579 tied to the Wall Street Journal prime rate, which 00:17:50.579 --> 00:17:53.380 is what's called a spot index. A spot index can 00:17:53.380 --> 00:17:55.359 change immediately based on what the Federal 00:17:55.359 --> 00:17:58.319 Reserve does. So if the Fed raises rates, your 00:17:58.319 --> 00:18:02.299 ELOC rate can, in theory, jump straight up that 00:18:02.299 --> 00:18:05.319 day all the way to that 18 percent state ceiling. 00:18:05.500 --> 00:18:09.119 Wow. There's no gentle periodic cap to protect 00:18:09.119 --> 00:18:11.700 you. That makes the distinction crystal clear. 00:18:12.250 --> 00:18:15.390 A standard ARM is designed to shield you from 00:18:15.390 --> 00:18:18.069 immediate catastrophic change, even if it eventually 00:18:18.069 --> 00:18:21.769 pushes your rate higher. ELOC, on the other hand, 00:18:21.829 --> 00:18:24.430 offers almost no protection from that period 00:18:24.430 --> 00:18:27.269 -to -period volatility. As the ARM evolved, you 00:18:27.269 --> 00:18:28.849 know, lenders were always trying to find that 00:18:28.849 --> 00:18:31.289 sweet spot, that balance between giving the borrower 00:18:31.289 --> 00:18:33.130 some stability and making sure the lender's risk 00:18:33.130 --> 00:18:35.369 was covered. And this led to some really powerful 00:18:35.369 --> 00:18:37.630 new versions, starting with the hybrid ARM. The 00:18:37.630 --> 00:18:40.170 hybrid ARM. Yes. This sounds like an attempt 00:18:40.170 --> 00:18:42.309 to get the best of both worlds, the security 00:18:42.309 --> 00:18:44.650 of a fixed rate and the low cost of an adjustable 00:18:44.650 --> 00:18:48.079 one. It's the great compromise. A hybrid ARM 00:18:48.079 --> 00:18:50.220 has a rate that's fixed for an initial period. 00:18:50.319 --> 00:18:53.619 It could be 3, 5, 7, even 10 years. And then 00:18:53.619 --> 00:18:56.140 after that period is over, it automatically converts 00:18:56.140 --> 00:18:58.779 into a regular ARM that adjusts annually for 00:18:58.779 --> 00:19:01.339 the rest of the loan. And we use that XY terminology 00:19:01.339 --> 00:19:04.859 to describe them. Right, X over Y, where X is 00:19:04.859 --> 00:19:06.859 the number of years in that initial fixed period 00:19:06.859 --> 00:19:09.359 and Y is the adjustment interval after that. 00:19:09.789 --> 00:19:13.230 The classic example is the 51 ARM. Oh, 51 ARM. 00:19:13.410 --> 00:19:15.809 So fixed for the first five years, and then it 00:19:15.809 --> 00:19:18.390 adjusts once a year for the remaining 25 years. 00:19:18.470 --> 00:19:20.650 Exactly. It gives you a five -year window of 00:19:20.650 --> 00:19:22.670 total stability. That's enough time to plan, 00:19:22.849 --> 00:19:25.049 maybe refinance, or hopefully earn more money 00:19:25.049 --> 00:19:27.130 before that inevitable adjustment finally hits. 00:19:27.250 --> 00:19:29.450 The hybrid ARM became incredibly popular in the 00:19:29.450 --> 00:19:32.369 early 2000s. It was an absolute explosion. In 00:19:32.369 --> 00:19:35.890 1998, hybrid ARMs were, what, less than 2 % of 00:19:35.890 --> 00:19:38.910 new 30 -year mortgages? Just six years later, 00:19:39.150 --> 00:19:42.230 That number had soared to 27 .5 % of the market. 00:19:42.589 --> 00:19:45.170 Lenders love them. Borrowers love them for the 00:19:45.170 --> 00:19:47.309 lower initial payments. It just seemed like a 00:19:47.309 --> 00:19:50.450 win -win. But the hybrid, as you said, is relatively 00:19:50.450 --> 00:19:53.869 safe compared to its wild cousin, the auction 00:19:53.869 --> 00:19:57.170 ARM, also known as the pick -a -payment ARM. 00:19:57.430 --> 00:20:00.200 This is where the danger just skyrockets. the 00:20:00.200 --> 00:20:02.559 option arm is unique because it starts by offering 00:20:02.559 --> 00:20:05.240 you four different monthly payment options it 00:20:05.240 --> 00:20:06.980 gives you this incredible cash flow flexibility 00:20:06.980 --> 00:20:09.579 which sounds great but it introduced a level 00:20:09.579 --> 00:20:11.619 of rift we'd never seen before so what were those 00:20:11.619 --> 00:20:14.559 four payment options you could choose from one 00:20:14.559 --> 00:20:17.680 the standard 30 -year fully amortizing payment 00:20:17.680 --> 00:20:21.079 that's the safest option okay two a 15 -year 00:20:21.079 --> 00:20:23.000 fully amortizing payment if you wanted to pay 00:20:23.000 --> 00:20:26.299 it down faster three an interest -only payment 00:20:26.299 --> 00:20:28.799 where your loan balance never goes down and four 00:20:29.630 --> 00:20:31.609 The minimum payment. The minimum payment. And 00:20:31.609 --> 00:20:33.990 that was often based on a ridiculously low teaser 00:20:33.990 --> 00:20:36.549 rate, like 1%. Correct. And that fourth option, 00:20:36.650 --> 00:20:38.910 the minimum payment, is the gateway to that toxic 00:20:38.910 --> 00:20:40.950 feature we mentioned earlier, negative amortization. 00:20:41.190 --> 00:20:44.170 So when you choose a payment that's less than 00:20:44.170 --> 00:20:46.480 the interest you actually owe. The math of your 00:20:46.480 --> 00:20:49.200 debt completely reverses. Let's use simple numbers. 00:20:49.500 --> 00:20:51.740 Say the interest due this month on your loan 00:20:51.740 --> 00:20:54.700 is $1500. But you choose the minimum payment 00:20:54.700 --> 00:20:57.440 option, which might only be $1000. You have a 00:20:57.440 --> 00:21:01.220 shortfall of $500. And that $500... It doesn't 00:21:01.220 --> 00:21:03.839 just vanish. No, it is immediately added right 00:21:03.839 --> 00:21:05.940 back onto your outstanding principal balance. 00:21:06.220 --> 00:21:10.220 So if your principal was $250 ,000, now it's 00:21:10.220 --> 00:21:13.960 $250 ,500. And next month, you're paying interest 00:21:13.960 --> 00:21:16.519 on that higher balance. You are actively digging 00:21:16.519 --> 00:21:19.279 yourself deeper into debt with every single minimum 00:21:19.279 --> 00:21:21.519 payment. This was marketed so heavily during 00:21:21.519 --> 00:21:23.680 the housing boom. It let people qualify for much 00:21:23.680 --> 00:21:25.460 bigger houses because they were being approved 00:21:25.460 --> 00:21:28.519 based on that tiny minimum payment, not on their 00:21:28.519 --> 00:21:30.650 ability to actually pay the full interest. That's 00:21:30.650 --> 00:21:32.910 exactly right. The problem is that negative amortization 00:21:32.910 --> 00:21:35.789 can't go on forever. This whole mechanism leads 00:21:35.789 --> 00:21:38.069 directly to the payment shock trigger, which 00:21:38.069 --> 00:21:40.289 happens when the loan is forced to recast. And 00:21:40.289 --> 00:21:41.690 there are two ways that can happen. The first 00:21:41.690 --> 00:21:44.539 is by reaching the neg -am cap. Right. Every 00:21:44.539 --> 00:21:48.140 option ARM had a contractual limit on how high 00:21:48.140 --> 00:21:50.579 your principal balance could grow, usually between 00:21:50.579 --> 00:21:54.119 110 % and 125 % of what you originally borrowed. 00:21:54.359 --> 00:21:57.539 So you take out a $200 ,000 loan with a 110 % 00:21:57.539 --> 00:22:01.500 cap the moment your balance hit $220 ,000 because 00:22:01.500 --> 00:22:03.740 of all that unpaid interest. The loan recasts. 00:22:03.900 --> 00:22:06.440 Immediately. And when it recasts, the payment 00:22:06.440 --> 00:22:08.380 doesn't just gently adjust. The minimum payment 00:22:08.380 --> 00:22:10.819 option is gone forever and your new payment is 00:22:10.819 --> 00:22:14.109 instantly reset to a fully - level over the remaining 00:22:14.109 --> 00:22:17.750 term at the current fully indexed rate. The payment 00:22:17.750 --> 00:22:20.769 jump could be 50 percent, 75 percent, even double 00:22:20.769 --> 00:22:22.769 what you were paying overnight. And the second 00:22:22.769 --> 00:22:25.180 trigger is just a deadline. The automatic recast 00:22:25.180 --> 00:22:27.559 date. This was usually mandated every five years. 00:22:27.700 --> 00:22:29.559 It didn't matter what your NEGAM balance was. 00:22:29.799 --> 00:22:31.859 On the fifth anniversary, the loan automatically 00:22:31.859 --> 00:22:33.960 adjusted to fully pay off over the remaining 00:22:33.960 --> 00:22:36.279 term at the current rate. Even if you were super 00:22:36.279 --> 00:22:38.480 careful, that fifth year still hit you with that 00:22:38.480 --> 00:22:41.500 massive payment recalculation. So the ideal borrower 00:22:41.500 --> 00:22:43.480 for this kind of product has to be an absolute 00:22:43.480 --> 00:22:46.960 financial whiz. They really do. Option arms are 00:22:46.960 --> 00:22:49.900 only suited for very sophisticated borrowers. 00:22:50.059 --> 00:22:52.539 People with growing or fluctuating high incomes, 00:22:52.799 --> 00:22:55.309 someone who who expects a huge bonus and can 00:22:55.309 --> 00:22:57.910 manage short -term cash flow, but is fully prepared 00:22:57.910 --> 00:23:00.349 to pay down all that accrued negative amortization 00:23:00.349 --> 00:23:03.289 before the recast date hits. For the average 00:23:03.289 --> 00:23:05.230 homeowner, this product was just a financial 00:23:05.230 --> 00:23:07.750 time bomb. OK, let's pivot and talk about the 00:23:07.750 --> 00:23:11.859 big picture here, the why. why did banks invent 00:23:11.859 --> 00:23:15.380 and then push these incredibly complex, high 00:23:15.380 --> 00:23:18.019 -risk products? And the answer, as you touched 00:23:18.019 --> 00:23:21.160 on, goes back to a core vulnerability in banking 00:23:21.160 --> 00:23:24.200 itself, the asset liability mismatch. This is 00:23:24.200 --> 00:23:25.859 the heart of the whole matter. A bank's business 00:23:25.859 --> 00:23:27.920 model is to take in short -term liabilities, 00:23:28.039 --> 00:23:29.660 that's basically your deposits, which they might 00:23:29.660 --> 00:23:31.759 have to pay you back tomorrow, and they use that 00:23:31.759 --> 00:23:34.180 money to issue long -term assets, which are mortgages 00:23:34.180 --> 00:23:36.720 fixed for 25 or 30 years. So if the bank is paying 00:23:36.720 --> 00:23:38.859 depositors 1%, but they have a mortgage locked 00:23:38.859 --> 00:23:41.380 in at 5%, everything's great. But what happens 00:23:41.380 --> 00:23:43.059 if the Federal Reserve jacks up interest rates 00:23:43.059 --> 00:23:44.980 and suddenly the bank has to pay 8 percent just 00:23:44.980 --> 00:23:47.680 to keep those deposits? That is the nightmare 00:23:47.680 --> 00:23:50.180 scenario for a bank. Their cost of funding, their 00:23:50.180 --> 00:23:52.880 liability is now higher than the income they're 00:23:52.880 --> 00:23:55.599 getting from their asset. That mismatch puts 00:23:55.599 --> 00:23:58.059 the entire bank's survival at risk. And the source 00:23:58.059 --> 00:24:01.099 material is very clear that this was the flaw 00:24:01.099 --> 00:24:03.960 that made the U .S. savings and loan crisis in 00:24:03.960 --> 00:24:07.539 the early 1980s so much worse. Explain that connection, 00:24:07.740 --> 00:24:09.900 because that's a huge moment in financial history. 00:24:10.200 --> 00:24:12.980 The S &L crisis was fundamentally driven by this 00:24:12.980 --> 00:24:16.400 mismatch. The S &Ls were sitting on huge portfolios 00:24:16.400 --> 00:24:19.160 of old, low -interest, fixed -rate mortgages. 00:24:19.480 --> 00:24:21.519 When Paul Volcker, who was the Fed chairman, 00:24:21.799 --> 00:24:24.180 aggressively raised interest rates to fight inflation, 00:24:24.579 --> 00:24:27.980 the S &Ls had to start paying, say, 15 % or more 00:24:27.980 --> 00:24:30.259 to their depositors just to stop them from pulling 00:24:30.259 --> 00:24:32.180 their money out. But their income from those 00:24:32.180 --> 00:24:34.819 old mortgages was locked in at 6 % or 7%. They 00:24:34.819 --> 00:24:36.640 were losing a massive amount of money on every 00:24:36.640 --> 00:24:39.480 single loan they held. It drove widespread insolvency. 00:24:39.500 --> 00:24:41.799 and was a huge contributor to the crisis. And 00:24:41.799 --> 00:24:44.700 the ARM was the direct structural solution to 00:24:44.700 --> 00:24:46.660 make sure that never happened again. Exactly. 00:24:47.079 --> 00:24:51.079 By offering ARMs, the bank transfers that interest 00:24:51.079 --> 00:24:54.519 rate risk to you, the borrower. They guarantee 00:24:54.519 --> 00:24:56.799 that their income from the mortgage, which is 00:24:56.799 --> 00:24:59.579 index plus margin, moves in lockstep with their 00:24:59.579 --> 00:25:02.220 own cost of funds, which is the index. They hedge 00:25:02.220 --> 00:25:04.839 their risk perfectly. And it's important to realize 00:25:04.839 --> 00:25:07.380 that outside the U .S., the variable rate loan 00:25:07.380 --> 00:25:10.460 isn't the specialty product. It's often the default. 00:25:10.700 --> 00:25:13.519 It is the standard structure. Variable rate or 00:25:13.519 --> 00:25:15.660 tracker mortgages are the most common way people 00:25:15.660 --> 00:25:18.380 buy homes in the U .K., Ireland, Canada, Australia, 00:25:18.640 --> 00:25:21.640 and New Zealand. In Canada, for example, your 00:25:21.640 --> 00:25:24.440 mortgage might be for 25 years, but the longest 00:25:24.440 --> 00:25:26.779 you can typically fix the rate for is 10 years, 00:25:26.980 --> 00:25:30.140 often much shorter. Why is the UK in particular 00:25:30.140 --> 00:25:33.119 so reliant on variable rates? It's tied to the 00:25:33.119 --> 00:25:35.059 history of their building societies, which have 00:25:35.059 --> 00:25:37.519 always dominated the mortgage market there. By 00:25:37.519 --> 00:25:39.740 law, these societies have to raise at least half 00:25:39.740 --> 00:25:41.720 of their funding from customer deposits. Ah, 00:25:41.920 --> 00:25:43.740 so they're heavily reliant on those short -term 00:25:43.740 --> 00:25:46.500 liabilities. Exactly. And because of that, they 00:25:46.500 --> 00:25:48.940 overwhelmingly prefer to issue variable rate 00:25:48.940 --> 00:25:51.380 mortgages. It's a structural preference that 00:25:51.380 --> 00:25:53.359 ensures they aren't exposed to that interest 00:25:53.359 --> 00:25:55.900 rate risk between their funding costs and their 00:25:55.900 --> 00:25:58.240 lending income. Now let's look at the contrast. 00:25:58.700 --> 00:26:01.099 Fixed rate systems like in Germany and Austria, 00:26:01.299 --> 00:26:04.539 how do they offer long -term fixed rates without 00:26:04.539 --> 00:26:07.400 facing that same asset liability threat? They 00:26:07.400 --> 00:26:11.480 do it through a very unique and restrictive model. 00:26:11.660 --> 00:26:14.259 It's centered on these institutions called Bospark 00:26:14.259 --> 00:26:16.119 Kessen, which are mutual building societies. 00:26:16.700 --> 00:26:19.819 They do offer long -term fixed loans, but the 00:26:19.819 --> 00:26:22.839 system forces you into mandatory savings for 00:26:22.839 --> 00:26:25.500 years up front. A forced savings plan. It's a 00:26:25.500 --> 00:26:27.779 prerequisite, essentially. You, the borrower, 00:26:27.880 --> 00:26:30.319 have to save up a significant fixed percentage 00:26:30.319 --> 00:26:32.819 of the loan amount in regular monthly installments 00:26:32.819 --> 00:26:34.960 before you're even allowed to get the mortgage. 00:26:35.160 --> 00:26:36.690 And you can't just show it with a loan. Some 00:26:36.690 --> 00:26:39.009 you have to save over time. That structure guarantees 00:26:39.009 --> 00:26:41.349 stability for sure. The payment is fixed years 00:26:41.349 --> 00:26:44.569 in advance. But it requires a level of long -term 00:26:44.569 --> 00:26:46.609 planning that might not work in a more mobile 00:26:46.609 --> 00:26:49.250 economy. It's really aimed at once -in -a -lifetime 00:26:49.250 --> 00:26:51.869 buyers who can plan their finances a decade ahead. 00:26:52.210 --> 00:26:54.470 The source material suggests that even in those 00:26:54.470 --> 00:26:56.930 countries, if you expect to move or refinance 00:26:56.930 --> 00:26:59.930 within, say, three to seven years, the lower 00:26:59.930 --> 00:27:02.549 rate you'd get from an ARM's introductory period 00:27:02.549 --> 00:27:05.460 can still be the better financial option. Let's 00:27:05.460 --> 00:27:07.599 close this part with a history of how the ARM 00:27:07.599 --> 00:27:10.000 actually came to be in the U .S. So the very 00:27:10.000 --> 00:27:12.740 first variable rate product was authorized in 00:27:12.740 --> 00:27:15.900 1980. It was called the Renegotiable Rate Mortgage, 00:27:15.900 --> 00:27:19.779 or RRM. It was a very cautious first step. The 00:27:19.779 --> 00:27:21.660 rate could only change every three years, and 00:27:21.660 --> 00:27:23.599 the life cap was only five percentage points. 00:27:23.880 --> 00:27:26.599 And then in 1982, the floodgates opened. The 00:27:26.599 --> 00:27:29.140 Garn -Saint -Germain Depository Institutions 00:27:29.140 --> 00:27:32.339 Act of 1982, that's the law that fully authorized 00:27:32.339 --> 00:27:34.740 the creation and widespread use of... adjustable 00:27:34.740 --> 00:27:37.299 rate mortgages as we know them today. It gave 00:27:37.299 --> 00:27:39.339 lenders the tool they felt they needed to stabilize 00:27:39.339 --> 00:27:41.539 their balance sheets. That tool was later massively 00:27:41.539 --> 00:27:44.420 misused. In 2006, right before the financial 00:27:44.420 --> 00:27:47.519 crisis, over 90 % of all subprime mortgages were 00:27:47.519 --> 00:27:51.599 arms. 90%. And subprime loans were 20 % of the 00:27:51.599 --> 00:27:54.769 entire market. That concentration meant that 00:27:54.769 --> 00:27:57.609 this instrument of risk transfer was placed overwhelmingly 00:27:57.609 --> 00:27:59.829 in the hands of the most financially vulnerable 00:27:59.829 --> 00:28:03.210 borrowers, which, you know, set the stage for 00:28:03.210 --> 00:28:05.269 the wave of foreclosures that came next. So if 00:28:05.269 --> 00:28:07.269 we connect that history to the actual mechanics 00:28:07.269 --> 00:28:10.650 of the ARM, the really profound risk isn't just 00:28:10.650 --> 00:28:12.970 that rates might go up. It's the operational 00:28:12.970 --> 00:28:15.650 complexity of the loan itself. And it's just 00:28:15.650 --> 00:28:18.289 overwhelming potential for systematic error and 00:28:18.289 --> 00:28:21.230 in some cases for deliberate predatory practices. 00:28:22.029 --> 00:28:24.130 Let's start with that intent. When does a financial 00:28:24.130 --> 00:28:26.170 product that's meant for risk management cross 00:28:26.170 --> 00:28:28.779 the line and become a predatory loan? Well, according 00:28:28.779 --> 00:28:31.460 to consumer advocates, an ARM becomes predatory 00:28:31.460 --> 00:28:33.640 when it's sold to someone who is clearly not 00:28:33.640 --> 00:28:35.480 going to be able to handle the rising payments 00:28:35.480 --> 00:28:37.740 if and when rates go up. So if you're approved 00:28:37.740 --> 00:28:40.420 based only on that 1 % teaser rate. And you have 00:28:40.420 --> 00:28:43.599 absolutely no ability to pay the real fully indexed 00:28:43.599 --> 00:28:46.059 rate of 5 % or 6%, that's considered predatory. 00:28:46.380 --> 00:28:48.319 Because the lender knows that payment shock is 00:28:48.319 --> 00:28:50.420 not just possible, it's inevitable. And for that 00:28:50.420 --> 00:28:52.759 borrower, it will be unaffordable. The caps and 00:28:52.759 --> 00:28:55.000 the rules are supposed to protect people. But 00:28:55.000 --> 00:28:57.319 what happens if the banks and the servicers managing 00:28:57.319 --> 00:29:00.079 these incredibly complex loans can't even do 00:29:00.079 --> 00:29:02.339 the math right themselves? This is where the 00:29:02.339 --> 00:29:04.900 source material gets truly shocking. We're talking 00:29:04.900 --> 00:29:07.299 about the interest rate error epidemic of the 00:29:07.299 --> 00:29:10.500 1990s, the complexity of the nine features, the 00:29:10.500 --> 00:29:12.640 different indices, the three adjustment mechanisms. 00:29:12.880 --> 00:29:15.220 It just completely overwhelmed the companies 00:29:15.220 --> 00:29:17.980 servicing the loans. So tell us about the findings 00:29:17.980 --> 00:29:21.319 of that 1991 Government Accountability Office 00:29:21.319 --> 00:29:24.240 study, the GAO study. The GAO looked at about 00:29:24.240 --> 00:29:27.700 12 million ARM loans in the U .S. They concluded 00:29:27.700 --> 00:29:31.400 that a staggering 20 % to 25 % of them had interest 00:29:31.400 --> 00:29:33.779 rate errors. One in every four or five loans 00:29:33.779 --> 00:29:36.059 was wrong. That's what they found. One former 00:29:36.059 --> 00:29:38.180 federal banking auditor estimated that these 00:29:38.180 --> 00:29:41.940 mistakes led to at least $10 billion in net overcharges 00:29:41.940 --> 00:29:44.299 to American homeowners. This wasn't just a few 00:29:44.299 --> 00:29:46.960 mistakes. It was systemic. $10 billion. What 00:29:46.960 --> 00:29:48.680 were the actual mistakes they were making? How 00:29:48.680 --> 00:29:51.440 does that happen? It was very technical, administrative 00:29:51.440 --> 00:29:54.099 stuff. The servicer would use the wrong bait 00:29:54.099 --> 00:29:56.480 for the index value. So they'd use last month's 00:29:56.480 --> 00:29:58.519 number instead of this month's or they'd use 00:29:58.519 --> 00:30:00.720 the wrong margin or they would just completely 00:30:00.720 --> 00:30:03.799 ignore the periodic or lifetime caps and overcharge 00:30:03.799 --> 00:30:06.259 the borrower anyway. The computer systems they 00:30:06.259 --> 00:30:08.279 had just weren't adequate to track all the moving 00:30:08.279 --> 00:30:10.839 parts. And the problem actually got worse, not 00:30:10.839 --> 00:30:14.079 better. It did. By December of 1995, another 00:30:14.079 --> 00:30:16.640 government study came out. It concluded that 00:30:16.640 --> 00:30:19.180 the error rate had actually gone up. They found 00:30:19.180 --> 00:30:23.279 that 50 % to 60 % of all adjustable rate mortgages 00:30:23.279 --> 00:30:25.319 in the United States contained a calculation 00:30:25.319 --> 00:30:28.119 error. Half of them. An absolute majority of 00:30:28.119 --> 00:30:30.160 the loans were being serviced incorrectly. And 00:30:30.160 --> 00:30:32.700 the estimated interest overcharges in that study 00:30:32.700 --> 00:30:36.059 alone exceeded $8 billion. 50 % to 60%. Yeah. 00:30:36.140 --> 00:30:38.650 That's not a margin of error. That is a complete 00:30:38.650 --> 00:30:41.049 operational failure of the system that was supposed 00:30:41.049 --> 00:30:43.710 to administer these loans. The complexity was 00:30:43.710 --> 00:30:46.529 literally self -defeating. The study blamed inadequate 00:30:46.529 --> 00:30:49.430 computer programs, clerical errors when filling 00:30:49.430 --> 00:30:51.910 out the documents, and just basic calculation 00:30:51.910 --> 00:30:55.829 mistakes. It shows this deep paradox. The very 00:30:55.829 --> 00:30:57.910 instrument designed to protect these sophisticated 00:30:57.910 --> 00:31:00.529 financial institutions was too mathematically 00:31:00.529 --> 00:31:02.849 complex for those same institutions to manage 00:31:02.849 --> 00:31:05.150 correctly. What's really unsettling to me is 00:31:05.150 --> 00:31:07.869 the timeline. The government finds that half 00:31:07.869 --> 00:31:11.470 or more of these loans are wrong in 1995. So 00:31:11.470 --> 00:31:13.250 what did they do to check on it after that? This 00:31:13.250 --> 00:31:15.890 is maybe the most shocking detail from the source 00:31:15.890 --> 00:31:18.410 material. No other comprehensive government studies 00:31:18.410 --> 00:31:21.369 have been conducted into ARM interest overcharges 00:31:21.369 --> 00:31:25.049 since that 1995 report. That silence is deafening. 00:31:25.210 --> 00:31:27.569 I mean, if the system was fundamentally broken 00:31:27.569 --> 00:31:29.670 in the mid -90s, the fact that no one followed 00:31:29.670 --> 00:31:32.690 up suggests one of two things. Either the industry 00:31:32.690 --> 00:31:34.549 fixed itself perfectly, which seems unlikely. 00:31:35.309 --> 00:31:37.750 Or the political will to expose that level of 00:31:37.750 --> 00:31:40.230 operational failure just vanished. The complexity 00:31:40.230 --> 00:31:42.549 itself becomes a shield against accountability. 00:31:42.930 --> 00:31:45.430 And this problem isn't just a U .S. thing. We 00:31:45.430 --> 00:31:47.990 saw a huge international scandal in Ireland that 00:31:47.990 --> 00:31:50.230 showed it wasn't just errors, but calculated 00:31:50.230 --> 00:31:53.269 adverse actions against customers. You're talking 00:31:53.269 --> 00:31:55.299 about the tracker mortgage scandal. Right. In 00:31:55.299 --> 00:31:58.079 2015, the Irish central bank started a massive 00:31:58.079 --> 00:32:01.119 investigation. These tracker mortgages in Ireland 00:32:01.119 --> 00:32:03.400 were very transparent arms. They were linked 00:32:03.400 --> 00:32:06.259 directly to a European benchmark rate. Well, 00:32:06.339 --> 00:32:10.220 after the 2008 crisis. those European rates plummeted 00:32:10.220 --> 00:32:12.720 and these tracker mortgages became extremely 00:32:12.720 --> 00:32:15.259 low interest, which meant they were unprofitable 00:32:15.259 --> 00:32:18.160 for the banks. So the banks, realizing they were 00:32:18.160 --> 00:32:20.680 stuck in these bad contracts, systematically 00:32:20.680 --> 00:32:23.319 and deliberately started moving thousands of 00:32:23.319 --> 00:32:25.599 their customers off the cheap tracker mortgages 00:32:25.599 --> 00:32:28.599 and onto more expensive variable rate products. 00:32:28.940 --> 00:32:31.220 So this wasn't a mistake. This was a deliberate 00:32:31.220 --> 00:32:34.339 strategy to get out of a contract that had become 00:32:34.339 --> 00:32:37.180 too good for the borrower. It confirms that when 00:32:37.180 --> 00:32:39.779 the A .R. This instrument of risk transfer actually 00:32:39.779 --> 00:32:42.480 works too well in the borrower's favor. Sometimes 00:32:42.480 --> 00:32:44.819 the lender will take deliberate action to claw 00:32:44.819 --> 00:32:47.740 that advantage back. So you, the borrower, have 00:32:47.740 --> 00:32:49.960 to be vigilant, not just against market changes 00:32:49.960 --> 00:32:52.539 or honest mistakes, but against the calculated 00:32:52.539 --> 00:32:55.380 self -interest of your loan servicer. So after 00:32:55.380 --> 00:32:58.460 all of this, what does it all mean? We've taken 00:32:58.460 --> 00:33:00.859 a really deep dive into the adjustable rate mortgage. 00:33:00.940 --> 00:33:04.740 And what we found is a powerful but mathematically 00:33:04.740 --> 00:33:07.880 intricate tool. It's incredibly effective for 00:33:07.880 --> 00:33:10.859 lenders. It lets them dramatically reduce their 00:33:10.859 --> 00:33:13.359 risk, protecting their business model from the 00:33:13.359 --> 00:33:15.759 whims of the market. And for the borrower, it's 00:33:15.759 --> 00:33:18.299 a way to get a lower initial payment to get into 00:33:18.299 --> 00:33:21.240 a home sooner. But those benefits, they demand 00:33:21.240 --> 00:33:23.619 an exceptionally high degree of sophistication 00:33:23.619 --> 00:33:25.900 from you, the borrower. You have to be able to 00:33:25.900 --> 00:33:27.980 track the index, understand the difference between 00:33:27.980 --> 00:33:31.359 a hybrid and an option ARM, calculate what negative 00:33:31.359 --> 00:33:33.740 amortization is doing to your balance, and know 00:33:33.740 --> 00:33:36.019 the precise limits of your risk because of the 00:33:36.019 --> 00:33:38.440 cap structure. The stability and the certainty 00:33:38.440 --> 00:33:40.980 of the 30 -year fixed rate, that's really the 00:33:40.980 --> 00:33:43.559 premium you pay. to offload all of that complexity. 00:33:43.819 --> 00:33:46.140 You're paying more to transfer that rate risk 00:33:46.140 --> 00:33:49.460 entirely back to the lender. The core choice 00:33:49.460 --> 00:33:51.839 really hinges on whether you are willing and 00:33:51.839 --> 00:33:54.500 able to bear that interest rate risk in exchange 00:33:54.500 --> 00:33:57.339 for a lower initial cost. It's a transaction 00:33:57.339 --> 00:33:59.480 that trades today's affordability for tomorrow's 00:33:59.480 --> 00:34:02.859 uncertainty. raises an important final question 00:34:02.859 --> 00:34:04.539 for you to think about. Considering those historical 00:34:04.539 --> 00:34:07.640 findings that 50 to 60 percent of ARMs in the 00:34:07.640 --> 00:34:10.300 U .S. had calculation errors and the fact that 00:34:10.300 --> 00:34:11.940 the government hasn't followed up on that for 00:34:11.940 --> 00:34:14.739 nearly three decades, if this instrument is so 00:34:14.739 --> 00:34:16.780 complex that the lenders and servicers themselves 00:34:16.780 --> 00:34:19.000 routinely make multi -billion dollar mistakes, 00:34:19.260 --> 00:34:21.639 how confident can the average borrower really 00:34:21.639 --> 00:34:23.739 be in their own ability to monitor and verify 00:34:23.739 --> 00:34:26.760 the true cost of their loan over 30 years? What 00:34:26.760 --> 00:34:28.940 is the real hidden cost of all that complexity 00:34:28.940 --> 00:34:31.760 when the very system designed to track your payments 00:34:31.760 --> 00:34:34.539 routinely fail. The ultimate step you have to 00:34:34.539 --> 00:34:36.639 take if you enter an agreement like this is to 00:34:36.639 --> 00:34:39.619 demand radical transparency and maybe even secure 00:34:39.619 --> 00:34:41.539 an independent third -party audit to make sure 00:34:41.539 --> 00:34:43.579 the burden of being vigilant doesn't just result 00:34:43.579 --> 00:34:45.460 in you becoming the next overcharged statistic.
