WEBVTT 00:00:00.000 --> 00:00:02.359 Welcome back to the Deep Dive. You're here because 00:00:02.359 --> 00:00:05.759 you need that shortcut, right? The clearest analysis 00:00:05.759 --> 00:00:08.259 of these really complex market mechanics that 00:00:08.259 --> 00:00:11.300 drive huge trading volumes in ways you might 00:00:11.300 --> 00:00:13.779 not expect. Exactly. Today, we're going to cut 00:00:13.779 --> 00:00:16.019 right through the jargon. We're tackling a foundational 00:00:16.019 --> 00:00:18.940 action, something that happens deep in the financial 00:00:18.940 --> 00:00:22.039 world's plumbing that dictates billions of dollars 00:00:22.039 --> 00:00:25.199 of activity on, well, on highly predictable dates. 00:00:25.339 --> 00:00:27.539 And we've synthesized a whole collection of sources 00:00:27.539 --> 00:00:29.739 for you today. We're going to peel back the layers 00:00:29.739 --> 00:00:33.140 on this one mechanism, moving way past the simple 00:00:33.140 --> 00:00:37.539 definition to explore the deep structural needs 00:00:37.539 --> 00:00:40.579 of institutional finance. So our mission for 00:00:40.579 --> 00:00:42.859 you today is to really get you to a point of 00:00:42.859 --> 00:00:44.600 mastery on this concept of rolling contracts. 00:00:44.840 --> 00:00:46.939 That's the goal. Okay, let's unpack this then. 00:00:47.000 --> 00:00:49.579 Our sources, they really zeroed in on what seems 00:00:49.579 --> 00:00:52.539 like a simple, almost... almost an administrative 00:00:52.539 --> 00:00:54.979 task in investing. It's called rolling a contract. 00:00:55.359 --> 00:00:58.020 It sounds totally benign, but as you said, in 00:00:58.020 --> 00:00:59.859 structured finance, this is a non -negotiable 00:00:59.859 --> 00:01:02.880 requirement and it sets off these massive concentrated 00:01:02.880 --> 00:01:05.760 trading events. It really does. So our objective 00:01:05.760 --> 00:01:10.120 for you today is, let's say threefold. First, 00:01:10.340 --> 00:01:12.359 we want you to understand the precise mechanics 00:01:12.359 --> 00:01:15.200 of the role. You know, what you actually sell 00:01:15.200 --> 00:01:18.659 and what you buy. Okay. Second, to grasp the 00:01:18.659 --> 00:01:20.829 core motivations. We're going to look at the 00:01:20.829 --> 00:01:24.109 two big ones, a preference for a specific duration 00:01:24.109 --> 00:01:28.129 and market liquidity. And the third. And third, 00:01:28.310 --> 00:01:31.989 to analyze the inevitable result, this collective 00:01:31.989 --> 00:01:34.569 market behavior that this predictability causes, 00:01:34.730 --> 00:01:37.730 which traders know as congestion. Let's lay the 00:01:37.730 --> 00:01:39.909 absolute foundation first then. What is the technical 00:01:39.909 --> 00:01:42.329 definition here? The source material says very 00:01:42.329 --> 00:01:44.980 clearly. That rolling a contract means trading 00:01:44.980 --> 00:01:47.299 out of a contract that you hold. Right. And then 00:01:47.299 --> 00:01:49.099 buying the contract with the next longest maturity. 00:01:49.379 --> 00:01:51.939 And that is the core engine. But the why is everything. 00:01:52.200 --> 00:01:54.420 The goal is the whole point. This whole maneuver, 00:01:54.540 --> 00:01:56.959 this two -step process, is all about maintaining 00:01:56.959 --> 00:01:59.620 a position with what the market calls constant 00:01:59.620 --> 00:02:01.799 maturity. Constant maturity. That is the key 00:02:01.799 --> 00:02:03.540 phrase you need to remember today. You're not 00:02:03.540 --> 00:02:05.920 just, you know, closing one position and opening 00:02:05.920 --> 00:02:07.939 another one randomly. No. You're systematically 00:02:07.939 --> 00:02:11.780 engineering your portfolio to... in a way, resist 00:02:11.780 --> 00:02:15.219 the passage of time. OK, so that idea, this constant 00:02:15.219 --> 00:02:18.280 maturity requirement, that's where the real complexity 00:02:18.280 --> 00:02:22.020 begins, isn't it? Why are fund managers so fixated 00:02:22.020 --> 00:02:24.979 on this, on maintaining a stable timeline for 00:02:24.979 --> 00:02:27.479 their positions? Why not just let a contract 00:02:27.479 --> 00:02:30.180 expire, let it mature naturally? Well, it's a 00:02:30.180 --> 00:02:33.580 mathematical and a risk management imperative. 00:02:33.939 --> 00:02:36.479 Think about it. You have a bond or maybe a derivative 00:02:36.479 --> 00:02:39.860 with a fixed expiration date. Every single day 00:02:39.860 --> 00:02:42.240 that goes by, the maturity of that contract gets 00:02:42.240 --> 00:02:44.319 shorter. Sure, makes sense. And that isn't a 00:02:44.319 --> 00:02:46.960 minor detail. It fundamentally changes the financial 00:02:46.960 --> 00:02:49.219 characteristics of the instrument. Specifically, 00:02:49.479 --> 00:02:51.919 it changes its sensitivity to things like interest 00:02:51.919 --> 00:02:53.879 rates. Ah, so we're talking about duration here, 00:02:53.919 --> 00:02:56.300 aren't we? We are absolutely talking about duration. 00:02:56.759 --> 00:02:59.479 It's probably the most critical measure of a 00:02:59.479 --> 00:03:02.060 fixed income securities price sensitivity to 00:03:02.060 --> 00:03:04.759 changes in interest rates. I mean, a 30 year 00:03:04.759 --> 00:03:08.280 bond is way, way more sensitive to a quarter 00:03:08.280 --> 00:03:10.780 point change in rates than, say, a six month 00:03:10.780 --> 00:03:13.879 T -bill is. Right. So when a five year contract 00:03:13.879 --> 00:03:16.639 just naturally ages and becomes a four year contract, 00:03:16.840 --> 00:03:19.819 its duration shrinks. And this means its volatility 00:03:19.819 --> 00:03:22.199 changes, its hedging characteristics change. 00:03:22.340 --> 00:03:25.330 If an institution's entire mandate is to hedge 00:03:25.330 --> 00:03:27.750 against long -term risk, letting their contracts 00:03:27.750 --> 00:03:30.610 drift shorter just makes their hedge. Well, it 00:03:30.610 --> 00:03:32.830 makes it ineffective over time. So if I'm an 00:03:32.830 --> 00:03:34.930 investor and I started out wanting a five -year 00:03:34.930 --> 00:03:37.550 position, after two years, I suddenly find myself 00:03:37.550 --> 00:03:39.550 holding something with a three -year risk profile. 00:03:39.750 --> 00:03:41.610 That's completely different from what I originally 00:03:41.610 --> 00:03:43.909 intended. Precisely. So the constant maturity 00:03:43.909 --> 00:03:46.469 rule is the action that actively fights against 00:03:46.469 --> 00:03:49.449 that time decay. It keeps the risk profile static. 00:03:49.650 --> 00:03:51.430 It's even more than just fighting time decay. 00:03:51.550 --> 00:03:54.069 It's also about managing something called convexity. 00:03:54.349 --> 00:03:56.770 Convexity, I mean, to put it simply, it measures 00:03:56.770 --> 00:03:59.629 how the duration of a bond changes as interest 00:03:59.629 --> 00:04:02.389 rates themselves change. Okay, so it's like a... 00:04:02.680 --> 00:04:04.379 A second order effect. That's a great way to 00:04:04.379 --> 00:04:06.939 put it. And when a bond or a contract gets closer 00:04:06.939 --> 00:04:09.740 to maturity, its convexity generally drops a 00:04:09.740 --> 00:04:12.479 lot. So by rolling into a longer dated contract, 00:04:12.819 --> 00:04:15.439 they are essentially resetting that convexity 00:04:15.439 --> 00:04:18.339 profile, making sure the portfolio behaves predictably 00:04:18.339 --> 00:04:21.500 when rates get volatile. For institutions that 00:04:21.500 --> 00:04:24.399 are modeling these incredibly complex risk metrics, 00:04:24.639 --> 00:04:26.959 you know, stable duration and predictable convexity 00:04:26.959 --> 00:04:29.660 are absolutely non -negotiable. That makes the 00:04:29.660 --> 00:04:32.610 whole process sound less like. like speculative 00:04:32.610 --> 00:04:35.370 trading and more like specialized portfolio maintenance, 00:04:35.490 --> 00:04:37.529 like a systematic scheduled adjustment. That's 00:04:37.529 --> 00:04:39.629 exactly what it is. It's a foundational part 00:04:39.629 --> 00:04:42.310 of the portfolio management process for huge 00:04:42.310 --> 00:04:44.910 players. This leads us right into section one. 00:04:45.389 --> 00:04:48.370 The core mechanic, why constant maturity matters. 00:04:48.670 --> 00:04:50.589 So we've kind of established the mathematical 00:04:50.589 --> 00:04:53.850 why. Now let's really focus on the how and the 00:04:53.850 --> 00:04:55.949 specific market mandates that are driving all 00:04:55.949 --> 00:04:57.810 this action. Yeah. And if we connect this to 00:04:57.810 --> 00:04:59.889 the bigger picture of institutional investing, 00:04:59.990 --> 00:05:02.350 this idea of constant maturity, it isn't just 00:05:02.350 --> 00:05:04.990 a preference. It's a necessary input for all 00:05:04.990 --> 00:05:07.110 their sophisticated risk models. What do you 00:05:07.110 --> 00:05:09.910 mean by that? Well, large investment banks, pension 00:05:09.910 --> 00:05:13.290 funds, asset managers, they all use standardized 00:05:13.290 --> 00:05:16.149 duration targets to calculate their capital requirements, 00:05:16.470 --> 00:05:19.269 to stress test their portfolios, and to maintain 00:05:19.269 --> 00:05:22.790 something called asset liability matching. Without 00:05:22.790 --> 00:05:25.470 a stable duration benchmark, their whole risk 00:05:25.470 --> 00:05:28.430 framework just kind of collapses into guesswork. 00:05:28.610 --> 00:05:31.050 Let's get really explicit then and deconstruct 00:05:31.050 --> 00:05:33.069 the physical action just as the source material 00:05:33.069 --> 00:05:35.410 laid it out. It's that two -step maneuver, right? 00:05:35.449 --> 00:05:37.519 And it's executed almost at the same time. Right. 00:05:37.740 --> 00:05:40.939 Step one, you sell the existing contract. This 00:05:40.939 --> 00:05:42.860 is what's called the nearby or the front month 00:05:42.860 --> 00:05:45.379 contract. It just means it's the one whose maturity 00:05:45.379 --> 00:05:47.779 is getting close. So its duration has dropped 00:05:47.779 --> 00:05:50.139 below their target. Exactly. So that contract 00:05:50.139 --> 00:05:53.220 gets liquidated because its risk profile just 00:05:53.220 --> 00:05:55.819 doesn't fit the mandate anymore. And then step 00:05:55.819 --> 00:05:58.560 two is immediately purchasing the contract with 00:05:58.560 --> 00:06:01.449 the next longest maturity. The deferred or the 00:06:01.449 --> 00:06:03.810 back month contract. Yes. And that immediately 00:06:03.810 --> 00:06:05.829 resets the position right back to the desired 00:06:05.829 --> 00:06:08.389 duration. And the result, as we've been saying, 00:06:08.509 --> 00:06:12.810 is this consistency in market exposure. The fundamental 00:06:12.810 --> 00:06:15.310 risk the investor is taking, let's say it's exposure 00:06:15.310 --> 00:06:18.629 to five -year interest rate shifts. That risk 00:06:18.629 --> 00:06:21.509 stays stable, even though the actual piece of 00:06:21.509 --> 00:06:23.310 paper, the instrument they hold, has changed. 00:06:23.569 --> 00:06:27.649 It's a continuous, active repositioning to neutralize 00:06:27.649 --> 00:06:29.670 time. So now we can dig into the motivations. 00:06:30.069 --> 00:06:32.930 Our sources cite two main reasons for going through 00:06:32.930 --> 00:06:35.370 all this effort. The first one is having a special 00:06:35.370 --> 00:06:38.370 preference for a specific maturity. And the source 00:06:38.370 --> 00:06:40.730 gave a really specific and I think a very insightful 00:06:40.730 --> 00:06:43.629 example here. It was preferring a specific rate, 00:06:43.689 --> 00:06:46.209 like the five -year CDS rate of a given name. 00:06:46.410 --> 00:06:49.009 Okay, let's break that down. CDS is a credit 00:06:49.009 --> 00:06:51.610 default swap. It's basically insurance against 00:06:51.610 --> 00:06:53.550 a company or a country going bankrupt, right? 00:06:53.629 --> 00:06:55.589 That's it. It's a derivative that's used to transfer 00:06:55.589 --> 00:06:57.629 credit risk. For the listener, a CDS contract 00:06:57.629 --> 00:07:00.449 is pretty standardized. You pay a premium, like 00:07:00.449 --> 00:07:03.189 an insurance premium, every year. And if the 00:07:03.189 --> 00:07:05.569 entity you're insuring, say a big corporation, 00:07:05.709 --> 00:07:08.649 defaults, you get paid out. But why the five 00:07:08.649 --> 00:07:10.970 years specifically? Why is that so important 00:07:10.970 --> 00:07:12.750 that you would constantly be rolling contracts 00:07:12.750 --> 00:07:15.160 just to maintain it? Because the five year maturity 00:07:15.160 --> 00:07:17.620 is the international standard, particularly in 00:07:17.620 --> 00:07:20.259 corporate and sovereign credit markets. It is 00:07:20.259 --> 00:07:22.899 the most liquid, the most quoted and the most 00:07:22.899 --> 00:07:25.100 heavily referenced benchmark maturity on the 00:07:25.100 --> 00:07:28.589 entire planet. Wow. Banks, institutions, they 00:07:28.589 --> 00:07:31.029 use the five year CDS rate for more than just 00:07:31.029 --> 00:07:33.649 trading. They use it for crucial functions like 00:07:33.649 --> 00:07:36.149 marking their books to market, for regulatory 00:07:36.149 --> 00:07:38.970 reporting, for calculating counterparty risk. 00:07:39.350 --> 00:07:42.529 It's the lingua franca of credit risk. So if 00:07:42.529 --> 00:07:45.550 a huge global bank is using a CDS rate to hedge 00:07:45.550 --> 00:07:47.949 its exposure to, I don't know, a major European 00:07:47.949 --> 00:07:50.769 bank, their hedge has to be anchored to that 00:07:50.769 --> 00:07:52.810 five year mark. It has to be. If they just let 00:07:52.810 --> 00:07:55.079 it drift down to three years. the hedge is no 00:07:55.079 --> 00:07:57.459 longer aligned with the market standard. And 00:07:57.459 --> 00:07:59.699 that complicates everything from their accounting 00:07:59.699 --> 00:08:02.420 to their regulatory compliance. You've got it. 00:08:02.439 --> 00:08:04.579 If you're managing a portfolio of credit risk, 00:08:04.740 --> 00:08:08.220 your goal is pure credit exposure. You don't 00:08:08.220 --> 00:08:10.379 want duration risk messing with your models. 00:08:10.519 --> 00:08:13.279 So by constantly rolling, you isolate the credit 00:08:13.279 --> 00:08:15.800 risk from the duration risk. You are ensuring 00:08:15.800 --> 00:08:18.740 that you are always, always measuring the cost 00:08:18.740 --> 00:08:21.000 of five years of protection because that's what 00:08:21.000 --> 00:08:23.279 the market fundamentally cares about. So it's 00:08:23.279 --> 00:08:25.720 a standardization play. It is. It's driven by 00:08:25.720 --> 00:08:28.579 both market convention and, frankly, regulatory 00:08:28.579 --> 00:08:30.899 necessity. That makes perfect sense for something 00:08:30.899 --> 00:08:33.080 specialized like derivatives. But the second 00:08:33.080 --> 00:08:35.500 motivation our sources pointed to is much broader. 00:08:35.639 --> 00:08:38.120 It touches on this universal need in finance. 00:08:38.960 --> 00:08:42.039 Liquidity. The desire to hold a security that 00:08:42.039 --> 00:08:44.340 is on the run because it is more liquid than 00:08:44.340 --> 00:08:46.659 off -the -run securities. And this is where the 00:08:46.659 --> 00:08:50.360 role moves from being a... a specialized necessity 00:08:50.360 --> 00:08:54.559 to a full blown mass market phenomenon. Liquidity, 00:08:54.659 --> 00:08:56.740 as we all know, it just means lower transaction 00:08:56.740 --> 00:09:00.399 costs, tighter bid ask spreads for huge institutions. 00:09:00.620 --> 00:09:03.240 Even a tiny, tiny saving per trade can translate 00:09:03.240 --> 00:09:05.399 into millions across a whole portfolio. And when 00:09:05.399 --> 00:09:07.700 you're managing trillions, prioritizing liquidity 00:09:07.700 --> 00:09:10.269 is just paramount. Absolutely. And that simple 00:09:10.269 --> 00:09:12.330 distinction, the one between the most current 00:09:12.330 --> 00:09:14.669 security and the one that's just slightly older, 00:09:14.889 --> 00:09:17.769 that's what creates this huge liquidity difference. 00:09:18.049 --> 00:09:20.970 It might seem arbitrary to an outsider, but that 00:09:20.970 --> 00:09:23.230 difference dictates trading behavior all over 00:09:23.230 --> 00:09:25.490 the globe. It really does. Because in so many 00:09:25.490 --> 00:09:27.529 of these standardized markets, the newest issue 00:09:27.529 --> 00:09:30.490 of a security or a contract, it just instantly 00:09:30.490 --> 00:09:32.909 attracts the deepest pool of buyers and sellers. 00:09:33.129 --> 00:09:35.350 And often that's because it's the easiest to 00:09:35.350 --> 00:09:37.690 locate and use for things like short selling 00:09:37.690 --> 00:09:40.940 for collateral. Which brings us perfectly to 00:09:40.940 --> 00:09:43.740 the most visible example of the role in action, 00:09:43.940 --> 00:09:46.519 the U .S. Treasury market. This is where it gets 00:09:46.519 --> 00:09:48.379 really interesting, because now we're focusing 00:09:48.379 --> 00:09:50.899 on the market behavior that this constant maturity 00:09:50.899 --> 00:09:54.379 mandate creates, especially this idea of an on 00:09:54.379 --> 00:09:56.860 -the -run premium. So this is Section 2, the 00:09:56.860 --> 00:09:59.379 concrete example U .S. Treasuries, on -the -run 00:09:59.379 --> 00:10:01.419 versus off -the -run. The U .S. Treasury market, 00:10:01.480 --> 00:10:03.440 I mean, it's the deepest, most liquid market 00:10:03.440 --> 00:10:06.299 in the world, and it perfectly illustrates the 00:10:06.299 --> 00:10:08.860 financial incentive to roll your position. The 00:10:08.860 --> 00:10:11.379 Treasury Department's issuance is highly structured, 00:10:11.600 --> 00:10:14.299 very predictable. They hold auctions at regular 00:10:14.299 --> 00:10:16.460 intervals for two year notes, 10 year notes, 00:10:16.620 --> 00:10:19.559 30 year bonds. It's like clockwork. So let's 00:10:19.559 --> 00:10:21.519 set the scene. An investor might want to hold 00:10:21.519 --> 00:10:24.320 only the most recently issued security of a given 00:10:24.320 --> 00:10:28.059 maturity. So my question is, why? Why does the 00:10:28.059 --> 00:10:30.480 simple designation of being the newest carry 00:10:30.480 --> 00:10:33.240 so much weight? Because that newest security, 00:10:33.519 --> 00:10:35.919 the on the run security, is immediately established 00:10:35.919 --> 00:10:38.500 as the market benchmark. It is used in nearly 00:10:38.500 --> 00:10:41.139 every transaction involving financing, collateral 00:10:41.139 --> 00:10:43.980 and trading strategies globally. It becomes the 00:10:43.980 --> 00:10:46.159 most actively traded security of its duration, 00:10:46.299 --> 00:10:48.860 which results in these razor thin bid ask spreads 00:10:48.860 --> 00:10:51.740 and just a massive depth of market. And at the 00:10:51.740 --> 00:10:54.340 exact same moment, the older security gets what 00:10:54.340 --> 00:10:57.379 downgraded? In a sense, yes. It becomes the off 00:10:57.379 --> 00:10:59.700 -the -run security the second a new auction happens. 00:11:00.360 --> 00:11:03.019 Now, functionally, it's still an obligation of 00:11:03.019 --> 00:11:05.500 the U .S. government. It has virtually identical 00:11:05.500 --> 00:11:09.019 credit risk and cash flows as the new bond, you 00:11:09.019 --> 00:11:11.120 know, apart from a tiny difference in time to 00:11:11.120 --> 00:11:13.500 maturity. But its liquidity profile just falls 00:11:13.500 --> 00:11:15.679 off a cliff. It shifts dramatically overnight. 00:11:16.100 --> 00:11:18.360 OK, this is a really crucial point for you to 00:11:18.360 --> 00:11:22.240 get. Two U .S. Treasury bonds might have coupons 00:11:22.240 --> 00:11:24.340 that are only, what, a sixteenth of a percent 00:11:24.340 --> 00:11:26.840 in part. Their time to maturity might only differ 00:11:26.840 --> 00:11:29.980 by a few months, but their market price can diverge 00:11:29.980 --> 00:11:32.539 significantly purely because of this preference 00:11:32.539 --> 00:11:35.039 for liquidity. And that divergence has a name. 00:11:35.299 --> 00:11:38.059 It's the liquidity premium. The on -the -run 00:11:38.059 --> 00:11:40.620 security trades at a slightly higher price, which 00:11:40.620 --> 00:11:42.779 means it has a slightly lower yield than its 00:11:42.779 --> 00:11:45.710 off -the -run twin. And that premium is the cost 00:11:45.710 --> 00:11:47.450 the market is willing to pay for that superior 00:11:47.450 --> 00:11:50.750 liquidity. And fungibility and ease of use as 00:11:50.750 --> 00:11:53.049 collateral in the repo market. It's often really 00:11:53.049 --> 00:11:55.370 small. I mean, maybe just a few basis points 00:11:55.370 --> 00:11:57.429 of yield difference. But when you apply that 00:11:57.429 --> 00:11:59.990 to trillions of dollars, it becomes a massive, 00:12:00.049 --> 00:12:02.379 massive number. So walk us through the actual 00:12:02.379 --> 00:12:05.059 process, the rolling process in practice. Let's 00:12:05.059 --> 00:12:07.820 use the 30 -year treasury example. How does an 00:12:07.820 --> 00:12:11.360 investor capture that liquidity while still maintaining 00:12:11.360 --> 00:12:13.899 their constant maturity? Okay, so it starts with 00:12:13.899 --> 00:12:16.759 the investor holding the current benchmark. Step 00:12:16.759 --> 00:12:19.980 one, they buy the existing on -the -run 30 -year 00:12:19.980 --> 00:12:22.039 treasury. They're happy. They have the most liquid 00:12:22.039 --> 00:12:24.200 asset of its kind. But the clock is ticking. 00:12:24.809 --> 00:12:28.009 And the market knows the exact moment this is 00:12:28.009 --> 00:12:31.730 all going to change. It does. So step two, a 00:12:31.730 --> 00:12:33.990 new 30 year option happens. The Treasury issues 00:12:33.990 --> 00:12:36.289 a new bond and it immediately takes the title 00:12:36.289 --> 00:12:39.009 of on the run. The old bond in that instant becomes 00:12:39.009 --> 00:12:41.490 off the run. And this is the trigger. This is 00:12:41.490 --> 00:12:43.470 what activates that constant maturity mandate. 00:12:43.730 --> 00:12:47.340 Step three, the investor executes the role. They 00:12:47.340 --> 00:12:49.299 sell the old treasury, which is now off the run. 00:12:49.360 --> 00:12:51.159 They're getting out of the contract whose liquidity 00:12:51.159 --> 00:12:53.519 is about to decline. And then step four, they 00:12:53.519 --> 00:12:55.580 immediately purchase the new on the run treasury. 00:12:55.679 --> 00:12:57.720 Right. They're trading into the contract that 00:12:57.720 --> 00:13:00.200 now has the highest liquidity and will be the 00:13:00.200 --> 00:13:02.820 preferred collateral asset for the entire next 00:13:02.820 --> 00:13:05.899 issuance cycle. And the primary motivation for 00:13:05.899 --> 00:13:08.440 all of this institutional churning, I mean, despite 00:13:08.440 --> 00:13:11.000 the transaction costs, is just that liquidity 00:13:11.000 --> 00:13:14.080 is king. It's all about optionality and collateral. 00:13:14.399 --> 00:13:16.299 That's really the bottom line. The on the run 00:13:16.299 --> 00:13:19.059 security is the easiest asset to deliver for 00:13:19.059 --> 00:13:21.580 margin requirements. It's the easiest to use 00:13:21.580 --> 00:13:23.899 in repurchase agreements repos to finance your 00:13:23.899 --> 00:13:26.259 other positions. And it's the simplest to short 00:13:26.259 --> 00:13:28.620 if you're hedging. So it's superior liquidity 00:13:28.620 --> 00:13:31.600 makes it the preferred tool for leverage. That's 00:13:31.600 --> 00:13:33.980 right. And investors are willing to pay that 00:13:33.980 --> 00:13:36.019 liquidity premium. They're willing to accept 00:13:36.019 --> 00:13:38.399 a slightly lower yield because it reduces their 00:13:38.399 --> 00:13:41.240 financing costs and it enhances their operation. 00:13:41.289 --> 00:13:44.710 flexibility. OK, but if the existence of this 00:13:44.710 --> 00:13:47.809 liquidity premium is so predictable, I mean, 00:13:47.809 --> 00:13:49.529 everyone knows the old bond will get cheaper 00:13:49.529 --> 00:13:51.129 relative to the new one right after the auction. 00:13:51.269 --> 00:13:53.549 Why hasn't high frequency trading or some kind 00:13:53.549 --> 00:13:56.049 of institutional arbitrage completely erased 00:13:56.049 --> 00:13:58.509 this phenomenon? That is a critical question. 00:13:58.629 --> 00:14:01.470 And the reason it persists is, well, it's about 00:14:01.470 --> 00:14:04.330 volume and execution risk. The liquidity premium 00:14:04.330 --> 00:14:07.289 has created this very popular and widely executed 00:14:07.289 --> 00:14:10.230 strategy called the treasury basis trade. The 00:14:10.230 --> 00:14:12.450 basis trade? Yeah, or sometimes the role basis 00:14:12.450 --> 00:14:15.330 trade. It involves doing two things at once. 00:14:16.039 --> 00:14:18.279 buying the relatively cheap off the run bond 00:14:18.279 --> 00:14:20.840 and shorting the relatively expensive on the 00:14:20.840 --> 00:14:23.799 run bond. The arbitrage is based on the idea 00:14:23.799 --> 00:14:26.419 that over time, the spread between those two 00:14:26.419 --> 00:14:29.580 will converge. Or that the financing costs will 00:14:29.580 --> 00:14:31.799 allow the trade to profit from the mispricing. 00:14:31.879 --> 00:14:35.120 Exactly. So funds are actively trying to exploit 00:14:35.120 --> 00:14:38.059 the very liquidity difference that the role itself 00:14:38.059 --> 00:14:39.779 creates. They're betting on this predictable 00:14:39.779 --> 00:14:42.200 price movement. But it's not a free lunch. Not 00:14:42.200 --> 00:14:44.659 at all. Executing this trade at scale is immensely 00:14:44.659 --> 00:14:48.019 challenging. The index role is a massive concentrated 00:14:48.019 --> 00:14:51.080 movement of capital and liquidity in the repo 00:14:51.080 --> 00:14:53.299 market, which is where the financing for the 00:14:53.299 --> 00:14:56.139 trade happens. That liquidity can just evaporate 00:14:56.139 --> 00:14:58.320 during periods of stress. So there's funding 00:14:58.320 --> 00:15:00.539 risk. There is huge liquidity risk or funding 00:15:00.539 --> 00:15:02.779 risk. And that's why the premium and the arbitrage 00:15:02.779 --> 00:15:05.980 opportunity persists. The arbitrage exists, but 00:15:05.980 --> 00:15:09.179 it is definitely not risk free, especially given 00:15:09.179 --> 00:15:11.259 the scale at which major hedge funds are trying 00:15:11.259 --> 00:15:14.039 to execute this basis trade. So it's the sheer 00:15:14.039 --> 00:15:16.899 transactional. tidal wave created by all these 00:15:16.899 --> 00:15:20.039 synchronized institutional mandates that keeps 00:15:20.039 --> 00:15:22.340 the market from being perfectly efficient in 00:15:22.340 --> 00:15:23.899 that little window of time. That's a perfect 00:15:23.899 --> 00:15:26.220 way to put it. And the market observation from 00:15:26.220 --> 00:15:28.740 our sources backs this up. It says, there is 00:15:28.740 --> 00:15:31.019 generally very high trading activity on these 00:15:31.019 --> 00:15:33.860 days as contracts whose maturity falls on them 00:15:33.860 --> 00:15:36.740 are rolled. That high activity is the physical 00:15:36.740 --> 00:15:40.340 proof of both the constant maturity mandate and 00:15:40.340 --> 00:15:42.919 the basis trading that's trying to exploit the 00:15:42.919 --> 00:15:46.220 price distortions. and that volume spike. It 00:15:46.220 --> 00:15:48.700 signals enormous synchronization. I mean, think 00:15:48.700 --> 00:15:50.899 of a major pension fund. Let's say it has a mandate 00:15:50.899 --> 00:15:53.460 to maintain $100 billion in a constant duration 00:15:53.460 --> 00:15:56.159 position. When that treasury auction occurs, 00:15:56.480 --> 00:15:59.240 that fund has to sell $100 billion of the old 00:15:59.240 --> 00:16:02.039 bond and buy $100 billion of the new bond, often 00:16:02.039 --> 00:16:04.299 within hours. And when you have hundreds of funds 00:16:04.299 --> 00:16:06.799 like that all acting at the same time, the market 00:16:06.799 --> 00:16:09.159 has to absorb hundreds of billions of dollars 00:16:09.159 --> 00:16:12.120 in coordinated selling and buying pressure. That's 00:16:12.120 --> 00:16:13.899 why the roll dates are consistently among the 00:16:13.899 --> 00:16:16.360 highest volume days for the... specific maturities. 00:16:16.600 --> 00:16:19.379 This concentrated burst of volume and the price 00:16:19.379 --> 00:16:22.039 distortion it causes, that on the run premium, 00:16:22.220 --> 00:16:24.679 it sets the perfect stage for our next section, 00:16:24.799 --> 00:16:27.019 where individual strategy scales up and creates 00:16:27.019 --> 00:16:29.940 systemic market effects. We're moving from a 00:16:29.940 --> 00:16:34.220 single funds decision to, well, to the predictable 00:16:34.220 --> 00:16:36.980 market chaos of congestion. That's right. The 00:16:36.980 --> 00:16:39.240 Treasury market is a really clear example, but 00:16:39.629 --> 00:16:42.470 This role mechanism is arguably even more critical 00:16:42.470 --> 00:16:45.250 and dramatic in the derivatives world, specifically 00:16:45.250 --> 00:16:47.909 in commodities and financial futures. And that 00:16:47.909 --> 00:16:50.470 brings us to Section 3, index role congestion, 00:16:50.809 --> 00:16:53.190 anticipating high volume. So we're shifting from 00:16:53.190 --> 00:16:55.370 an individual strategy to these broader market 00:16:55.370 --> 00:16:58.289 forces. And here, the predictability of the role 00:16:58.289 --> 00:17:00.070 isn't just a function of government auctions, 00:17:00.070 --> 00:17:02.970 but a function of the published public methodology 00:17:02.970 --> 00:17:05.730 of major financial indexes. This is so important 00:17:05.730 --> 00:17:08.380 to understand. When a big index like the S &P 00:17:08.380 --> 00:17:10.940 GSCI for commodities or the Bloomberg Commodity 00:17:10.940 --> 00:17:13.220 Index, when it holds futures contracts, it has 00:17:13.220 --> 00:17:15.660 to manage their expiration. Because futures contracts 00:17:15.660 --> 00:17:18.180 expire often every month or every quarter. They 00:17:18.180 --> 00:17:21.359 have strict short term expiration dates. So the 00:17:21.359 --> 00:17:24.180 index has to roll its holdings to the next contract 00:17:24.180 --> 00:17:26.960 maturity just to maintain continuous exposure 00:17:26.960 --> 00:17:28.900 to whatever it's tracking, whether that's oil 00:17:28.900 --> 00:17:33.019 or gold or a financial asset. And the key factor 00:17:33.019 --> 00:17:35.079 here, the thing that creates the trading opportunity, 00:17:35.220 --> 00:17:38.660 is that the index's movements are totally transparent. 00:17:39.789 --> 00:17:42.170 Explain the rules of the index. Well, an index, 00:17:42.369 --> 00:17:45.269 for the sake of continuity and fairness and transparency 00:17:45.269 --> 00:17:47.390 to the trillions of dollars that are benchmarked 00:17:47.390 --> 00:17:49.950 against it, it often has a meticulously published 00:17:49.950 --> 00:17:53.190 policy for rolling its contracts. This policy 00:17:53.190 --> 00:17:56.269 dictates the exact days or a precise period, 00:17:56.349 --> 00:17:59.349 say the fifth to the ninth business day before 00:17:59.349 --> 00:18:01.589 expiration during which the role has to happen. 00:18:02.109 --> 00:18:04.170 So this knowledge is public. It's basically a 00:18:04.170 --> 00:18:06.630 massive institutional announcement saying, hey, 00:18:06.690 --> 00:18:08.990 everyone, we're about to move X billion dollars 00:18:08.990 --> 00:18:11.130 between these two contracts on these exact days. 00:18:11.150 --> 00:18:13.150 You've got it. It's like a massive oil tanker 00:18:13.150 --> 00:18:15.089 that announces it will be navigating a very narrow 00:18:15.089 --> 00:18:17.829 straight next Tuesday at noon. And every speedboat 00:18:17.829 --> 00:18:20.329 and savvy tugboat captain knows exactly when 00:18:20.329 --> 00:18:22.329 and where to be. That's an excellent analogy. 00:18:23.049 --> 00:18:25.950 The savvy trader strategy is to exploit this 00:18:25.950 --> 00:18:28.730 public knowledge. The proactive trading technique 00:18:28.730 --> 00:18:31.430 that arises is that investors choose to roll 00:18:31.430 --> 00:18:34.470 in advance of the index. They do their own constant 00:18:34.470 --> 00:18:36.769 maturity roll days, or sometimes even weeks, 00:18:36.910 --> 00:18:39.470 before the index even begins its mandated trading 00:18:39.470 --> 00:18:41.829 window. People call this front -running the index 00:18:41.829 --> 00:18:43.630 roll, right? That's another term for it, yes. 00:18:43.849 --> 00:18:46.269 So what's the tactical motivation? Why do this 00:18:46.269 --> 00:18:49.480 early? Why not just... wait and save the transaction 00:18:49.480 --> 00:18:52.000 costs for a few days. The motivation for moving 00:18:52.000 --> 00:18:54.900 early is purely driven by the anticipation of 00:18:54.900 --> 00:18:57.799 the indexes trading volume and the market impact 00:18:57.799 --> 00:19:00.769 that it will inevitably create. Let's just visualize 00:19:00.769 --> 00:19:03.789 the flow of money. If a giant index is selling 00:19:03.789 --> 00:19:06.849 the nearby contract, that contract's price is 00:19:06.849 --> 00:19:08.349 going to face selling pressure. It's going to 00:19:08.349 --> 00:19:11.089 go down. And if that same index is buying the 00:19:11.089 --> 00:19:13.849 next longest maturity contract, that contract's 00:19:13.849 --> 00:19:15.930 price will see buying pressure. It'll go up. 00:19:16.150 --> 00:19:18.529 This shifts the spread between the two contracts, 00:19:18.769 --> 00:19:20.950 what's called the roll, spread unfavorably for 00:19:20.950 --> 00:19:22.509 anyone who tries to execute the trade during 00:19:22.509 --> 00:19:24.569 that main index window. Let's ground this in 00:19:24.569 --> 00:19:28.170 a hypothetical. Imagine a major index is tracking 00:19:28.170 --> 00:19:31.890 gold futures. and there's, say, $300 billion 00:19:31.890 --> 00:19:35.130 benchmarked against it. Okay. If the index policy 00:19:35.130 --> 00:19:37.730 says they have to roll, I don't know, 10 % of 00:19:37.730 --> 00:19:40.289 that position over a four -day window, that means 00:19:40.289 --> 00:19:44.210 $30 billion of flow, $15 billion of selling one 00:19:44.210 --> 00:19:46.289 contract, and $15 billion of buying the other 00:19:46.289 --> 00:19:51.109 has to get done. Exactly. Now, if you are a pension 00:19:51.109 --> 00:19:54.750 fund managing, say, $500 million, and $30 billion 00:19:54.750 --> 00:19:56.910 in flow is about to hit the market, you move 00:19:56.910 --> 00:20:00.279 early. If you wait, you risk executing your selling 00:20:00.279 --> 00:20:02.359 order at a lower price because of the index's 00:20:02.359 --> 00:20:04.980 systematic selling pressure, and you risk executing 00:20:04.980 --> 00:20:06.920 your buying order at a higher price because of 00:20:06.920 --> 00:20:09.140 the index's systematic buying pressure. So by 00:20:09.140 --> 00:20:11.220 rolling early, you get a better price on that 00:20:11.220 --> 00:20:13.359 roll spread before the massive volume distorts 00:20:13.359 --> 00:20:15.339 the market. You secure a better price. That's 00:20:15.339 --> 00:20:17.980 the entire game. And this resulting market phenomenon, 00:20:18.119 --> 00:20:20.180 this crowding of traders into the pre -index 00:20:20.180 --> 00:20:22.519 window, this is what we call index roll congestion. 00:20:22.900 --> 00:20:26.430 It is the systemic cost of predictability. Congestion 00:20:26.430 --> 00:20:28.809 happens because everybody anticipates the same 00:20:28.809 --> 00:20:31.210 massive flow and everybody tries to move ahead 00:20:31.210 --> 00:20:34.750 of it. The index roll is this huge, almost mechanical 00:20:34.750 --> 00:20:37.609 transfer of liquidity. And traders are just trying 00:20:37.609 --> 00:20:39.750 to position themselves to either benefit from 00:20:39.750 --> 00:20:43.529 or simply avoid the costs of that transfer. It 00:20:43.529 --> 00:20:46.009 creates a period of intense concentrated volume 00:20:46.009 --> 00:20:48.710 in the days right before the official index roll 00:20:48.710 --> 00:20:51.589 period. So this preemptive trading, it really 00:20:51.589 --> 00:20:54.089 forces us to analyze the significance of congestion. 00:20:54.890 --> 00:20:57.650 I mean, why does the anticipation of volume create 00:20:57.650 --> 00:21:01.390 this period of congestion that is costly and 00:21:01.390 --> 00:21:03.650 volatile? Why doesn't the market just smoothly 00:21:03.650 --> 00:21:06.589 absorb the knowledge of the upcoming trade? And 00:21:06.589 --> 00:21:08.250 that highlights a really important distinction 00:21:08.250 --> 00:21:11.829 between informational efficiency and transactional 00:21:11.829 --> 00:21:13.670 efficiency. The market is informationally efficient. 00:21:13.829 --> 00:21:16.190 Everyone knows the index rule is coming. But 00:21:16.190 --> 00:21:18.009 it is transactionally inefficient because of 00:21:18.009 --> 00:21:20.670 the sheer size of the flow. And the index is 00:21:20.670 --> 00:21:23.430 totally inflexible mandate. The index must execute. 00:21:23.960 --> 00:21:26.400 Regardless of the price. Regardless of the price. 00:21:26.559 --> 00:21:28.839 And traders know this is a temporary artificial 00:21:28.839 --> 00:21:32.400 price distortion. It's caused by mandated flow, 00:21:32.579 --> 00:21:35.160 not by some fundamental change in the market 00:21:35.160 --> 00:21:38.019 value of oil or gold. So the congestion is really 00:21:38.019 --> 00:21:40.039 the market temporarily front running itself. 00:21:40.200 --> 00:21:42.759 And the early movers are the ones who are capturing 00:21:42.759 --> 00:21:45.500 that predictable transient inefficiency. Yes. 00:21:46.140 --> 00:21:49.359 The very presence of congestion is powerful proof 00:21:49.359 --> 00:21:51.720 that the index flow is big enough to materially 00:21:51.720 --> 00:21:54.900 move prices. This dynamic makes the roll period 00:21:54.900 --> 00:21:58.220 a crucial and often very volatile time for futures 00:21:58.220 --> 00:22:00.599 traders. They'll adjust their short -term positions, 00:22:00.940 --> 00:22:03.259 those basis trades and arbitrage plays we talked 00:22:03.259 --> 00:22:06.059 about, specifically to capture the temporary 00:22:06.059 --> 00:22:08.619 widening or narrowing of the roll spread that 00:22:08.619 --> 00:22:11.059 happens during congestion. And the cost of this 00:22:11.059 --> 00:22:13.180 inefficiency, which must be measured in hundreds 00:22:13.180 --> 00:22:15.920 of millions of dollars, is effectively transferred 00:22:15.920 --> 00:22:18.460 from the passive funds that are just tracking 00:22:18.460 --> 00:22:21.039 the index to the active traders who front run 00:22:21.039 --> 00:22:22.880 the role. That's the transfer of wealth right 00:22:22.880 --> 00:22:25.079 there. This really shows the paradox we hinted 00:22:25.079 --> 00:22:27.700 at earlier. The institutional need for stability 00:22:27.700 --> 00:22:30.920 and consistency, that constant maturity mandate, 00:22:31.039 --> 00:22:33.400 is the very thing that creates these periodic, 00:22:33.579 --> 00:22:36.559 almost violent bursts of concentrated trading 00:22:36.559 --> 00:22:39.440 volume and market instability. It's stability 00:22:39.440 --> 00:22:42.339 creating instability. It is the ultimate irony 00:22:42.339 --> 00:22:44.740 of market structure, isn't it? Stability in your 00:22:44.740 --> 00:22:47.299 portfolio mandate requires mechanical, rules 00:22:47.299 --> 00:22:50.079 -based action. And rules -based action at massive 00:22:50.079 --> 00:22:52.480 scale creates predictable dislocations that are 00:22:52.480 --> 00:22:54.799 immediately exploited by opportunistic traders. 00:22:55.400 --> 00:22:57.539 Understanding the timing of the roll, whether 00:22:57.539 --> 00:22:59.839 it's the predictable treasury auction or that 00:22:59.839 --> 00:23:02.599 transparent futures index schedule, is the key 00:23:02.599 --> 00:23:04.880 to understanding those temporary volatility spikes 00:23:04.880 --> 00:23:07.920 you see in these sophisticated markets. We've 00:23:07.920 --> 00:23:09.849 covered a huge amount of ground here. We've moved 00:23:09.849 --> 00:23:11.950 from the mathematical necessity of constant duration 00:23:11.950 --> 00:23:14.890 all the way to the systematic strategy of index 00:23:14.890 --> 00:23:17.549 front running. So it's time for our final synthesis. 00:23:18.049 --> 00:23:20.849 So what does this all mean? Well, we've established 00:23:20.849 --> 00:23:23.380 that two -part. mechanism of the rule. You're 00:23:23.380 --> 00:23:25.980 selling the expiring or nearby contract and you're 00:23:25.980 --> 00:23:28.000 buying the next longest maturity. And this is 00:23:28.000 --> 00:23:30.359 all performed to achieve stability and duration 00:23:30.359 --> 00:23:33.339 and your risk profile. And we know the two big 00:23:33.339 --> 00:23:35.700 drivers. First, there's that specialized requirement 00:23:35.700 --> 00:23:38.359 to target a standardized benchmark, like the 00:23:38.359 --> 00:23:41.400 very liquid five -year CDS rate. And second, 00:23:41.519 --> 00:23:43.920 there's that relentless institutional desire 00:23:43.920 --> 00:23:46.660 to hold the most liquid asset possible, which 00:23:46.660 --> 00:23:49.140 is perfectly illustrated by the U .S. Treasury's 00:23:49.140 --> 00:23:53.079 on -the -run premium. encourages constant rolling, 00:23:53.299 --> 00:23:56.559 even with transaction costs. And critically, 00:23:56.839 --> 00:23:59.319 this strategy, when it's executed by these large 00:23:59.319 --> 00:24:01.859 rules -based indexes, it transforms the roll 00:24:01.859 --> 00:24:04.480 from a simple administrative task into a multi 00:24:04.480 --> 00:24:07.440 -billion dollar trading event. And the transparency 00:24:07.440 --> 00:24:09.960 of these mandates, that leads directly to index 00:24:09.960 --> 00:24:12.220 roll congestion, where active traders try to 00:24:12.220 --> 00:24:14.279 preempt the index's flow just to capture better 00:24:14.279 --> 00:24:16.539 prices, creating predictable volatility in the 00:24:16.539 --> 00:24:18.460 process. So what does this all mean for you? 00:24:18.559 --> 00:24:20.769 Well, it means that if you're watching... trading 00:24:20.769 --> 00:24:23.950 activity, and you see these massive concentrated 00:24:23.950 --> 00:24:28.009 spikes in volume for specific futures contracts 00:24:28.009 --> 00:24:30.869 or specific treasury bonds on these highly predictable 00:24:30.869 --> 00:24:34.369 dates, you are very likely witnessing the constant 00:24:34.369 --> 00:24:36.910 maturity roll and the resulting index congestion 00:24:36.910 --> 00:24:41.309 in real time. This is systematic, mandated trading. 00:24:41.450 --> 00:24:44.210 It's not organic, fundamental trading based on 00:24:44.210 --> 00:24:46.240 new information. And this raises a really important 00:24:46.240 --> 00:24:49.039 question. We saw that rolling while it's a strategy 00:24:49.039 --> 00:24:50.980 for consistency that actually introduces this 00:24:50.980 --> 00:24:53.680 transient volatility. But the concept of extending 00:24:53.680 --> 00:24:56.059 a financial position isn't limited just to futures 00:24:56.059 --> 00:24:58.559 and government debt, is it? How do other areas 00:24:58.559 --> 00:25:00.920 of finance implement this idea of position extension 00:25:00.920 --> 00:25:03.619 and what unique risks do they face? That's a 00:25:03.619 --> 00:25:06.180 great thought to build on. Our sources highlighted 00:25:06.180 --> 00:25:08.400 a couple of related concepts that show how this 00:25:08.400 --> 00:25:11.059 core principle of rolling applies to other, even 00:25:11.059 --> 00:25:13.740 more complex instruments. So for you, the listener, 00:25:13.839 --> 00:25:15.500 you need to be familiar with how this core idea 00:25:15.500 --> 00:25:18.339 evolves. And the first one they noted was the 00:25:18.339 --> 00:25:20.740 jelly roll in the world of options. And this 00:25:20.740 --> 00:25:23.079 is where the concept moves far beyond a simple 00:25:23.079 --> 00:25:26.559 sell -and -buy mechanic. A jelly roll. Okay, 00:25:26.599 --> 00:25:29.359 explain how rolling applies to a complex options 00:25:29.359 --> 00:25:32.700 strategy like that. What are the legs of this 00:25:32.700 --> 00:25:35.579 complex spread? A jelly roll is actually a highly 00:25:35.579 --> 00:25:38.799 sophisticated four -legged strategy. It's a type 00:25:38.799 --> 00:25:41.119 of calendar spread that involves four different 00:25:41.119 --> 00:25:43.960 options contracts. Typically, it involves selling 00:25:43.960 --> 00:25:46.160 a near -dated option spread, so that's a call 00:25:46.160 --> 00:25:48.160 and a put at certain strikes, and at the same 00:25:48.160 --> 00:25:50.640 time, buying a longer -dated option spread at 00:25:50.640 --> 00:25:53.579 the exact same strikes. So you might sell a January 00:25:53.579 --> 00:25:56.099 call -put combination and then buy the same call 00:25:56.099 --> 00:25:59.880 -put combination, but for, say, June. Precisely. 00:25:59.880 --> 00:26:01.819 So you're effectively rolling an entire options 00:26:01.819 --> 00:26:03.980 position, both your upside and your downside 00:26:03.980 --> 00:26:06.619 exposure from one maturity to the next. And often 00:26:06.619 --> 00:26:08.779 the goal is to lock in a profit or to maintain 00:26:08.779 --> 00:26:11.240 a specific risk profile without actually closing 00:26:11.240 --> 00:26:13.880 the position and creating a taxable event. So 00:26:13.880 --> 00:26:15.920 it's a way to extend the life of the trade. It 00:26:15.920 --> 00:26:18.880 is. It's often structured as a zero cost transaction 00:26:18.880 --> 00:26:21.400 or even one where you receive a small credit. 00:26:22.059 --> 00:26:24.700 The goal is to extend the life of a profitable 00:26:24.700 --> 00:26:27.740 position, or maybe a risk hedge, by using the 00:26:27.740 --> 00:26:29.759 money you get from the near -dated options to 00:26:29.759 --> 00:26:31.599 fund the purchase of the far -dated options. 00:26:31.880 --> 00:26:34.579 It uses the roll concept not just to maintain 00:26:34.579 --> 00:26:37.920 duration, but to specifically manage the time 00:26:37.920 --> 00:26:40.619 value decay, or theta, of the options position 00:26:40.619 --> 00:26:43.819 itself. It's a fascinating evolution of the basic 00:26:43.819 --> 00:26:47.000 constant maturity idea, but it's applied to volatility. 00:26:47.339 --> 00:26:49.819 Okay, and the second related concept was rollover. 00:26:50.299 --> 00:26:53.000 foreign exchange. How does this idea of extending 00:26:53.000 --> 00:26:55.619 maturity apply in the currency markets? They 00:26:55.619 --> 00:26:57.059 tend to have much shorter settlement periods. 00:26:57.259 --> 00:27:00.250 Right. In FX. Rollover refers to the process 00:27:00.250 --> 00:27:02.250 of extending the settlement date of a spot currency 00:27:02.250 --> 00:27:04.849 trade, typically from one day to the next. You 00:27:04.849 --> 00:27:07.230 see, Forex markets settle trades two business 00:27:07.230 --> 00:27:09.650 days after you execute them. It's called T plus 00:27:09.650 --> 00:27:12.250 two. If a trader doesn't want the actual currency 00:27:12.250 --> 00:27:14.069 to settle, they don't want to take delivery of 00:27:14.069 --> 00:27:16.470 millions of euros. They have to roll the position 00:27:16.470 --> 00:27:18.950 over to the next day. And that rollover, it isn't 00:27:18.950 --> 00:27:20.630 free, is it? There's an interest differential 00:27:20.630 --> 00:27:23.200 involved. Absolutely. This is where the carry 00:27:23.200 --> 00:27:25.799 component comes into play. Every currency pair 00:27:25.799 --> 00:27:28.000 involves two different countries, and those two 00:27:28.000 --> 00:27:29.680 countries have two different short -term interest 00:27:29.680 --> 00:27:32.779 rates. When you roll a position, you are effectively 00:27:32.779 --> 00:27:35.079 borrowing one currency and lending the other 00:27:35.079 --> 00:27:37.519 for a single day. So if the currency you're lending 00:27:37.519 --> 00:27:39.539 has a higher interest rate than the one you're 00:27:39.539 --> 00:27:40.960 borrowing... You receive interest. That's called 00:27:40.960 --> 00:27:43.420 positive carry. If it's the reverse, you pay 00:27:43.420 --> 00:27:45.940 interest, that's negative, Gary. So the rollover 00:27:45.940 --> 00:27:48.640 process in FX is this continuous daily assessment 00:27:48.640 --> 00:27:51.000 of interest rate differentials, which makes it 00:27:51.000 --> 00:27:54.019 a critical cost or benefit for currency speculators 00:27:54.019 --> 00:27:56.420 and hedgers alike.
