  1. 0:00What is happening in the US Treasury
  2. 0:03market. Hello everyone, guys, and
  3. 0:05welcome to this new video. I have
  4. 0:08decided to finally cover bond duration,
  5. 0:11since you've been asking me about it
  6. 0:14lately after I made a video on American
  7. 0:16bonds and what is going on. The first
  8. 0:21thing I would like to tell you is that
  9. 0:24on September 10th I will be speaking on
  10. 0:27the BNP Paribas channel around 9:25 or
  11. 0:299:30 in the morning. Secondly, and this
  12. 0:34is very important to me, on September
  13. 0:3618th, Renegade and I will do a live
  14. 0:39stream on memories; I’m 99%sure that
  15. 0:41Andrea Cartisano has confirmed it for
  16. 0:44me. We will do it on his channel at
  17. 0:476:00 PM. Okay. Guys, I am preparing all
  18. 0:51the live content, all the slides on
  19. 0:53memories. We truly have, look, so much
  20. 0:55stuff to talk about. They are very,
  21. 0:57very nice; I am making them on Canva
  22. 0:59and they are very, very detailed. I
  23. 1:02suggest you attend because, let's say,
  24. 1:04during this live stream we will also
  25. 1:07give a little bit of our view on what
  26. 1:09could be, how should I put it, what
  27. 1:12could be the end of the cycle or a
  28. 1:14recovery and rise for memories. I don't
  29. 1:17want to spoil anything for you, come to
  30. 1:19the live stream, see you there. So,
  31. 1:21let's try to take a moment to focus on
  32. 1:23what is happening in the American
  33. 1:25markets. The first thing I want to tell
  34. 1:29you is, if you remember, we have talked
  35. 1:31many times about the fact that yields
  36. 1:33tend to incorporate three things, okay?
  37. 1:37And I'll show them to you here. When we
  38. 1:38look at yields, in this case, you see
  39. 1:40on the thirty-year American bond we are
  40. 1:42at 5.235. We have growth expectations,
  41. 1:47that would be growth expectations plus
  42. 1:49inflation expectations plus term
  43. 1:51premium, so what does that mean? That
  44. 1:54if the economy rises and grows,
  45. 1:56therefore if there are positive growth
  46. 1:58expectations for the economy,
  47. 2:00consequently we must also have positive
  48. 2:02growth expectations for inflation,
  49. 2:04right? Because if the economy rises,
  50. 2:07most likely the price level of goods
  51. 2:09and services will also tend to rise.
  52. 2:13And then the term premium is obviously
  53. 2:15an important slice that concerns that
  54. 2:18risk premium the investor wants to
  55. 2:20receive for obviously investing longer
  56. 2:22over time. So, the longer the maturity,
  57. 2:27the more the term premium in theory
  58. 2:29should be, let's say, a slice that
  59. 2:30should cover a fairly important part
  60. 2:32within the yield calculation. So, if we
  61. 2:36compare a thirty-year and a ten-year,
  62. 2:38know well that there is an important
  63. 2:39difference. That said, obviously
  64. 2:43geopolitical tensions can also affect,
  65. 2:45okay, the term premium, but also the
  66. 2:47credibility or lack thereof of the
  67. 2:49Federal Reserve with respect to what is
  68. 2:52obviously the investors 'perception. So
  69. 2:56now we have a scenario that is quite,
  70. 2:58shall we say, peculiar, because on one
  71. 3:01hand, the U.S. Treasury wants to try to
  72. 3:04absorb a good portion of the duration.
  73. 3:08You will understand what I mean now. So
  74. 3:11they are trying to lower the yields on
  75. 3:14the long end of the curve, on the 10,
  76. 3:1620, and 30-year notes. How so? By
  77. 3:18conducting buybacks. Because we know
  78. 3:21that if a bond's price, okay, tends to
  79. 3:23increase, so if this is the bond price
  80. 3:25and it tends to go up, if these are the
  81. 3:28yields, the yields are inversely
  82. 3:30proportional and tend to go down. Okay?
  83. 3:34So if I have, let's say, a bond that I
  84. 3:36buy at 100 and it tends to rise, going
  85. 3:38to 101, 102, it very likely means that
  86. 3:41interest rates are falling, okay? I
  87. 3:44mean, no, it's not very likely, it's
  88. 3:45certainly the case. So what does that
  89. 3:47mean? That in this historical phase,
  90. 3:50Bessent declared that the buyback size
  91. 3:53will increase from 2 to 4 billion. Guys
  92. 3:57, by "size" we don't mean the totality
  93. 4:00of the buyback, also because with 4
  94. 4:02billion in U.S. debt you can't do
  95. 4:05anything, but it is the "size" per
  96. 4:07operation that can be executed, and I
  97. 4:10can guarantee you that a 4 billion
  98. 4:13buyback per operation on a 30-year bond
  99. 4:16makes a huge difference compared to a
  100. 4:19buyback you could do on a 10-year note,
  101. 4:22okay? or even on a 5-year bond, because
  102. 4:26the longer the expiration, so the
  103. 4:29maturity, the greater the duration,
  104. 4:33okay? It will be quite broad, so let me
  105. 4:36give you an example: a modified
  106. 4:38duration on a 30-year bond is around 16
  107. 4:41years. I will take you through the
  108. 4:43calculation now, so stay until the end
  109. 4:45of the video because I will do it for
  110. 4:46you step by step. Uh, the only thing I
  111. 4:49always want to tell you from a, let's
  112. 4:51say, macro point of view is that at
  113. 4:53this moment we are in a phase where, in
  114. 4:55my opinion, the Federal Reserve is in a
  115. 4:57phase, as they say in jargon, behind
  116. 4:58the curve, right? So behind the curve.
  117. 5:02For what reason? Because he gives
  118. 5:04absolutely no guidance, he doesn't
  119. 5:06anticipate any moves. So what does that
  120. 5:09mean? That Kevin Warsh, if he said "I
  121. 5:12will look at the trend, I will look at
  122. 5:14the data" and the Federal Reserve will
  123. 5:16have work to do, that's what he said,
  124. 5:18it will have work to do should
  125. 5:20inflation rise, it is obvious that you
  126. 5:22are telling the market that if and only
  127. 5:25if the Federal Reserve sees an
  128. 5:26increasing inflation trend, then it
  129. 5:28will act. In this case, you are not
  130. 5:31ahead of the curve, you are behind the
  131. 5:33curve. Actually, guys, more or less in
  132. 5:35the G20, in the G20 countries, the
  133. 5:37United States and Japan are in the same
  134. 5:39phase, and probably only Brazil is a
  135. 5:42little bit ahead of the curve. As for
  136. 5:44the rest, if you look, well, there's
  137. 5:46nothing, let's say, different. Behind
  138. 5:50the curve, just to explain it to you,
  139. 5:52means that the monetary authorities
  140. 5:54have, let's say, allowed inflationary
  141. 5:57dynamics to consolidate without
  142. 5:58properly and timely tightening
  143. 6:00financial conditions. So, the Fed is
  144. 6:04being criticized for having missed the
  145. 6:06inflation target for 5 years. Okay? In
  146. 6:09fact, if you've noticed, Kevin Warsh
  147. 6:11says it often, okay? During his
  148. 6:14meetings—he's only had three—it
  149. 6:16seems it's a recurring phrase, so I
  150. 6:18want you to understand that showing the
  151. 6:20market a certain independence of the
  152. 6:22Fed is definitely an important concept.
  153. 6:25Okay? So, right now, I see Kevin Warsh
  154. 6:28wanting to show strong credibility to
  155. 6:30the market, the independence of the Fed
  156. 6:33, and so he has a somewhat more hawkish
  157. 6:35tone. However, in fact, he hasn't
  158. 6:39mentioned any type of rate hike, and I
  159. 6:41still see a September hike as difficult
  160. 6:43, if I can give you my take, despite
  161. 6:46today's strong labor market data,
  162. 6:48especially thanks to—I'm talking
  163. 6:50about non-farm payrolls—especially
  164. 6:52thanks to the education level, because
  165. 6:55out of 162,000 payrolls, over 40,000
  166. 6:57came from, let's say, the education
  167. 6:59sector because it's a seasonal issue.
  168. 7:03It's August; you have to know that in
  169. 7:05America schools reopen already towards
  170. 7:07the end of August, so it's obvious
  171. 7:09there are these hires due to a seasonal
  172. 7:10effect. Okay, so let's keep that in
  173. 7:13mind too. But then the food sector also
  174. 7:16multiplied its hiring by five, so I
  175. 7:18must say I was particularly surprised
  176. 7:20by today's data. So, what did I want to
  177. 7:23tell you? Let's try to look at an
  178. 7:24example. So, we now need to understand
  179. 7:27what duration is and we need to, look,
  180. 7:29wait for me to move a bit higher up.
  181. 7:32Here we go. Let's select a—so, guys,
  182. 7:34I'm actually going to get a tablet
  183. 7:36because otherwise, writing here becomes
  184. 7:38complex. So, if we look at duration, it
  185. 7:42basically tells us, okay, by how much
  186. 7:44the value—I would call it, to make it
  187. 7:46simple for you, of a promise—changes.
  188. 7:50What do I mean? So, let's try to
  189. 7:53imagine that I have to give some money
  190. 7:55to a friend. Okay? Keep in mind that in
  191. 8:00finance, duration measures the
  192. 8:02sensitivity of a bond's price to
  193. 8:04changes in interest rates. That means
  194. 8:09if I increase rates by 1%, I want to
  195. 8:12understand the impact on the price of
  196. 8:15my bond. That's what I need to
  197. 8:19understand. Ok? So, the further away
  198. 8:23the maturity is, like we said before,
  199. 8:25if we consider a thirty-year bond, see,
  200. 8:2730 years, ok? The greater, excuse me,
  201. 8:32the longer the maturity, the higher the
  202. 8:33duration will be. This means that,
  203. 8:36generally, a 30-year bond undergoes
  204. 8:40massive price swings, even if interest
  205. 8:44rates move very little. And now we will
  206. 8:48try to get to that. Consider this: if
  207. 8:51we wanted to give a fairly simple
  208. 8:53example, we can use two examples, guys.
  209. 8:57So, I was telling you before, we have a
  210. 8:59friend who has to pay me back € 100.
  211. 9:02All right? I am giving you a really
  212. 9:05basic example, a truly simple, simple
  213. 9:07example. Imagine he has to give us €
  214. 9:09100. It's one thing if he gives them to
  215. 9:12me in a year. By Y I mean, ok? To be
  216. 9:14brief, because guys, it's not easy
  217. 9:16writing on these small boards. two. If
  218. 9:19these € 100, instead, a second friend
  219. 9:22wanted to give them to me in 30 years,
  220. 9:24what value will they have? And this is
  221. 9:28where we have to start reasoning,
  222. 9:31because in finance you absolutely must
  223. 9:33absorb the concept of discounted cash
  224. 9:36flows, otherwise, even when we talk in
  225. 9:39videos about uh discount rates, WACC,
  226. 9:42how we look at terminal value, why it
  227. 9:44gets crushed, for what reason? I want
  228. 9:48you to follow me, and so I decided to,
  229. 9:50uh, let's say, cover this in this video
  230. 9:52. It will certainly be a bit longer,
  231. 9:55guys, but if you stay focused, I'll
  232. 9:57show you it will all be simpler. So,
  233. 10:00now I'll erase this and show you
  234. 10:02something. The one-year one is
  235. 10:03obviously the friend who will give me
  236. 10:05the money right away, so let's say I
  237. 10:07have no impact. Ok? The 30-year one,
  238. 10:10instead, means that I remain locked in,
  239. 10:12and in the meantime, obviously, the
  240. 10:14market could offer higher returns. Ok?
  241. 10:18So the further away my cash flows are,
  242. 10:19the greater the duration will be, and
  243. 10:21the higher the sensitivity to rates I
  244. 10:23will have. Let's do a numerical example
  245. 10:27. So guys, if I have a Treasury, ok,
  246. 10:32we'll take the 30-year Treasury in this
  247. 10:34case, ok? And let's give it a face
  248. 10:40value, I'll give you an example, of $
  249. 10:42100, all right? Let's say, for example,
  250. 10:47the coupon is 5%, let's use simple
  251. 10:49numbers. The market return, so in this
  252. 10:53market, at this moment the market is
  253. 10:55pricing yields, ok? I'll do it here.
  254. 10:58Market return. Let's pretend the market
  255. 11:03is currently pricing Treasuries at 5%,
  256. 11:05see? It prices them at 5.238, but for
  257. 11:07the sake of calculation, I'll leave it
  258. 11:09at 5. And we said that the maturity, ok
  259. 11:13? The maturity is indeed 30 years. Very
  260. 11:19well. The essential thing we need for
  261. 11:24the calculations is that the coupons,
  262. 11:26look, must be semiannual, okay?
  263. 11:30Otherwise, we can't perform the
  264. 11:33calculations. So, remember that the
  265. 11:37duration tells us how far away in time
  266. 11:40the money that this bond, in fact, will
  267. 11:42have to return to me is. It’s not
  268. 11:45enough to say, "No, I will receive the
  269. 11:47money in 30 years." No, guys, that's
  270. 11:49incorrect; it doesn't work like that
  271. 11:50because that is only the final
  272. 11:52repayment. In the meantime, we will
  273. 11:54receive coupons, and I want to give you
  274. 11:56an example. So, for those of you
  275. 11:58following along, you might want to
  276. 12:00pause here and take these notes down;
  277. 12:02I'll erase and move on. So, I want to
  278. 12:05show you in a fairly simple way. What
  279. 12:08do I receive? I receive two points, $
  280. 12:142.50 in 6 months is the first coupon,
  281. 12:18right? Because we said the coupons are
  282. 12:20semiannual. If I get, I remind you here
  283. 12:23, 5%per year, in 6 months I will
  284. 12:25receive the first coupon of 2.50
  285. 12:27because, well, we pretended the bond
  286. 12:29only cost € 100, that I put € 100
  287. 12:32into the bond. Okay, very good. Pardon
  288. 12:35me, dollars. Then what happens? I get
  289. 12:40another 2.50 in a year, so for the
  290. 12:43moment, in one year I have received
  291. 12:462.50 + 2.50, which makes $ 5, which is
  292. 12:495%, okay? Based on 100. Then in a year
  293. 12:55and a half I get again, in 1.5 years I
  294. 12:58get what? Another $ 2.50, and so on. So
  295. 13:04, the duration performs a sort of
  296. 13:06weighted average of all these cash
  297. 13:07flows. Giving more weight to the flows
  298. 13:10that are worth more, obviously, today.
  299. 13:13Okay, I'll stop here, I'll erase to
  300. 13:16make space. Now we need to learn how to
  301. 13:18discount these flows. So, if I have a 5
  302. 13:22%annual yield, since we said it pays
  303. 13:24semiannually, what does that mean? That
  304. 13:28the 5%I mentioned before, divided by 2,
  305. 13:31gives me 2.5%every 6 months. Okay? Very
  306. 13:39good, so each payment is discounted
  307. 13:42every 6 months. So what do we do? We
  308. 13:46take a formula that starts with PV,
  309. 13:48which indicates the present value, and
  310. 13:50we go to see what the current value is,
  311. 13:51okay? And in the numerator, we put the
  312. 13:55cash flow, the future value. You will
  313. 13:57find it in a thousand ways. If you put
  314. 13:59"present value formula" into Google,
  315. 14:01okay, you'll find a thousand entries in
  316. 14:03the denominator, but which in the end
  317. 14:04—sorry, in the numerator—which in
  318. 14:06the end all lead to the same concept.
  319. 14:09So we can also put FV, which stands for
  320. 14:13future value, divided by 1 + r
  321. 14:16discounted, sorry, let me do it like
  322. 14:20this. 1 + here it is r, which is raised
  323. 14:28to the n. Okay? Now you need to
  324. 14:31consider one thing. If in finance we
  325. 14:34want to discount, that is, bring back
  326. 14:37to today's value money that I will
  327. 14:40receive in 6 months, I have to divide
  328. 14:42by 1 plus the discount rate. In this
  329. 14:46case, the 6-month discount rate is 2.5.
  330. 14:49What is the logical reason? It is the
  331. 14:51time value of money. Why? Because a
  332. 14:55dollar today—this you really need to
  333. 14:57get into your heads—a dollar I get
  334. 14:59today is greater, is worth more than a
  335. 15:01dollar I will collect tomorrow. This is
  336. 15:05exactly the time value we are assigning
  337. 15:07to money. So if the bank pays 2.5 every
  338. 15:106 months, how much money must I invest
  339. 15:13today to have $ 2.50 in 6 months? So
  340. 15:18what do I do? I take the PV formula,
  341. 15:22which is equal to 2.50/1 + 0.025
  342. 15:33because if you remember, in the
  343. 15:34denominator we had 1 + r. All of this
  344. 15:38is equal to 2.5/1.025 which equals—
  345. 15:46I'll tell you—2.43. What does that
  346. 15:51mean? If I divide by 1.025, it means
  347. 15:54that that payment of $ 2.50, guys, this
  348. 15:57one right here, okay? that I will
  349. 16:00receive in 6 months, since I cannot use
  350. 16:03it today, it's worth a little less in
  351. 16:05my pocket, let's say, in my wallet, and
  352. 16:07it is worth $ 2.43, because if I had
  353. 16:09that money today, I could earn 2.5%on
  354. 16:11it. Remember that in finance, the logic
  355. 16:15of opportunity cost always applies.
  356. 16:18Meaning, if in these 6 months I don't
  357. 16:21have the chance to invest, I am losing
  358. 16:24a 2.5%return. If the cash flow had been
  359. 16:28in a year, therefore two periods, how
  360. 16:30would I have divided it? By 1 + 0.025
  361. 16:36sq. Okay? If it had been in 3 years,
  362. 16:40therefore 6 six-month periods, I would
  363. 16:43have divided by 1 + 0.025 ^ 6, because
  364. 16:48if it's 3 years, okay guys, 3 years
  365. 16:52equals 6 six-month periods, okay?
  366. 16:57Because remember we are calculating
  367. 16:59based on the six-month coupon, and
  368. 17:02obviously if I do 2.5/1 + 0.025 ^ 6,
  369. 17:05the calculation starts to change
  370. 17:07drastically. Okay? Now, if you want to
  371. 17:13do all the calculations yourself, I
  372. 17:15suggest you build an Excel model, you
  373. 17:17make it once and for all, you save it,
  374. 17:19and basically the work to be done is
  375. 17:21this. You need to see the present value
  376. 17:24, okay? 2.5/1 + 0.025. This is the
  377. 17:31first one, then you do present value 2,
  378. 17:34and so on. 2.5/1 + 0.025 you square it,
  379. 17:41then you do the third. PV 3 = 2.5/1 +
  380. 17:470.025 ^ three and so on. Okay? until
  381. 17:54you eventually reach, just to be a bit
  382. 17:58faster, PV 60, because we said it's 30
  383. 18:01years, guys. So 30 years times two
  384. 18:05coupons per year because it's
  385. 18:06semi-annual, we have 102.50. And you'll
  386. 18:11say, Marco, why is there 102 in the
  387. 18:13numerator? Well yes, because at the
  388. 18:1660th semester we will have the
  389. 18:19repayment of 100, if obviously the bond
  390. 18:22is repaid at par, as in this case, plus
  391. 18:25the last coupon of 2.5. That's why
  392. 18:30102.50 divided by 1 + 0 raised to the
  393. 18:3660th. At the final maturity I receive,
  394. 18:40as I told you before, also, uh, let's
  395. 18:42say the principal, right? So if I added
  396. 18:45up, just to give you an example, guys,
  397. 18:48if I added up all the coupons received
  398. 18:52for the 59 quarters before reaching the
  399. 18:55last one, which is here, I could do 2.5
  400. 18:59*59 which is, wait let me do it, it's
  401. 19:02147.50. If I then add the final coupon
  402. 19:10+ 2.5 I arrive perfectly at 150. But
  403. 19:15future money is worth less than today's
  404. 19:18money, okay? Precisely because of
  405. 19:20inflation, the cost of money, and so on
  406. 19:22. So, if I take the sum of all the
  407. 19:26discounted values and the discounted
  408. 19:29values were obviously those, the result
  409. 19:32of all these divisions I was showing
  410. 19:34you, we had the first year 2 point,
  411. 19:37excuse me, the first semester 2.44,
  412. 19:402.38 and so on. Okay? If we think that
  413. 19:45the value 100 is a mathematical
  414. 19:47consequence, it is also inevitable that
  415. 19:49the coupon rate and the market yield
  416. 19:51are the same. But guys, I mean what
  417. 19:53does that mean? That everything I am
  418. 19:56telling you is valid as long as the
  419. 19:58market prices the Treasury always at 5%
  420. 20:00. Because what happens? And this is
  421. 20:04where we need to get to the reasoning.
  422. 20:07If a war suddenly breaks out, the Fed
  423. 20:10goes crazy, raises rates and the 30-
  424. 20:13year goes from 5 to 6%, for those
  425. 20:15holding bonds in their portfolio, bad
  426. 20:18times are coming. For what reason?
  427. 20:22Especially on long maturities and
  428. 20:23therefore high duration, right? Because
  429. 20:25if the maturity is long, the duration,
  430. 20:27which is not the maturity, let's not
  431. 20:29get confused, eh, that is a very very
  432. 20:32wrong thing. Anyway, um, what happens
  433. 20:35to the bond? the denominators, based on
  434. 20:37the calculations we did earlier, would
  435. 20:39become larger and therefore the present
  436. 20:41values of the coupons would decrease.
  437. 20:43Now we'll see it. The total would no
  438. 20:46longer be 100, but I'll tell you
  439. 20:49quickly, if we go from 5 to 6, the
  440. 20:51value of the bond drops between 85 and
  441. 20:5490, guys. So it reaches between -10 and
  442. 20:58-15%, and the bond goes below par. Okay
  443. 21:01? Let's get to our calculation. We must
  444. 21:05now consider that we need to explain
  445. 21:08duration well so that this concept is
  446. 21:10clear once and for all. For each cash
  447. 21:15flow, we must also assign the moment we
  448. 21:18receive it; that is, we multiply each
  449. 21:21individual discounted flow by the exact
  450. 21:23time in years when we will receive it.
  451. 21:27Let me give you an example. If I take,
  452. 21:30okay, the first semester, we can
  453. 21:33indicate it as 0.5 in terms of years,
  454. 21:37times the present value 1 that we had
  455. 21:40calculated, if you remember it was 2.50
  456. 21:44/1.025. which gave me 2.4344, okay?
  457. 21:51more or less, with a few decimals. If I
  458. 21:55multiply this by 0.5, and if we now do
  459. 21:58this for all the other flows, okay? So
  460. 22:02it would mean that for the second one
  461. 22:05we would have to do 2.50/1.025. Every
  462. 22:10now and then I’m a bit slanted, guys,
  463. 22:12forgive me. It is not easy to write
  464. 22:14with this pen and the small board, it
  465. 22:16really isn't easy, huh. Excuse me. The
  466. 22:19parenthesis, here we go, I messed it up
  467. 22:21, I made it too long. The parenthesis
  468. 22:22goes in the denominator. Squared, we
  469. 22:25said 2.38. If we multiply it by 1, why
  470. 22:30by 1? Because we are talking about two
  471. 22:32coupons, so the first year; the result
  472. 22:34obviously doesn't change, it's 2.38.
  473. 22:38Then we have to do a year and a half,
  474. 22:40we multiply by 1.5, and so on. If we
  475. 22:44add up all this calculation up to the
  476. 22:4760th, it means we have 30 in terms of
  477. 22:51years times PV60. Okay? What does that
  478. 22:56mean? That by summing everything up—
  479. 22:58I'll tell you the calculation already
  480. 22:59because I did it before starting the
  481. 23:00video, otherwise we'd never finish—it
  482. 23:02comes to 1584.07. I take this figure,
  483. 23:09okay? I divide it by what? by the price
  484. 23:13of the bond. And what does that come to
  485. 23:16? It comes to 15.84. So it means that
  486. 23:22ours is called the Macaulay duration,
  487. 23:25which is not the only duration, hey,
  488. 23:28now I'll show you another one. Macaulay
  489. 23:34Duration tells us that our capital will
  490. 23:37be returned in 15.84 years. So the
  491. 23:41duration, guys, of a thirty-year
  492. 23:44Treasury is 15.4. Okay? But the one
  493. 23:49that interests us later for the price
  494. 23:52is the modified duration, okay? So what
  495. 23:56does that mean? that we are going to
  496. 23:58look at the modified duration, because
  497. 24:01the Macaulay duration tells us that
  498. 24:03even though the bond lasts 30 years on
  499. 24:05paper, thanks to the fact that it pays
  500. 24:07coupons every 6 months, I recover the
  501. 24:09capital in more or less 16 years. Just
  502. 24:12to clarify a concept for you, how can I
  503. 24:14say that the capital is recovered in 16
  504. 24:16years? It doesn’t mean that we’ll
  505. 24:18recover everything by the 16th year,
  506. 24:19right? If I give you two examples, let
  507. 24:22me make a quick parenthetical note: we
  508. 24:24have a Case A where, for example, we
  509. 24:26have, I don’t know, a zero-coupon
  510. 24:28bond, okay? For the zero-coupon bond, I
  511. 24:33obviously wait for the repayment, so I
  512. 24:35have a duration of 30 years, right?
  513. 24:38Because I don't receive any coupons in
  514. 24:39the meantime. Case B, on the other hand
  515. 24:41, is the one we just looked at. In Case
  516. 24:45B, if we have a 30-year Treasury that
  517. 24:48pays coupons semiannually—so every 6
  518. 24:50months—my duration is around 16 years
  519. 24:53. 15.84, we saw it just a few seconds
  520. 24:57ago. Okay? This means the financial
  521. 25:01center of gravity of my returns, guys,
  522. 25:03in terms of cash flows, shifts backward
  523. 25:06. Because it goes from 30 years down to
  524. 25:1016 years. So, even though I have a
  525. 25:13maturity, okay, at the 30th year—so
  526. 25:16if today is 2026, my maturity is in
  527. 25:192056—my duration helps me understand
  528. 25:24that I'm actually shifting my center of
  529. 25:26gravity back to around 16 years, okay?
  530. 25:29So please, make sure to distinguish
  531. 25:31between maturity and duration; they are
  532. 25:34two different concepts. Now, therefore,
  533. 25:37we said that the number we saw earlier,
  534. 25:40which was 15.84, is the average
  535. 25:46financial duration of our 30-year
  536. 25:47Treasury, naturally weighted based on
  537. 25:49the time we receive the coupons. But to
  538. 25:53calculate how much the price drops if
  539. 25:56rates move, okay, in finance, we use
  540. 25:59modified duration. As I was saying
  541. 26:02earlier, the formula to move, guys,
  542. 26:05from, uh, Macaulay duration to modified
  543. 26:08duration is very simple. Basically,
  544. 26:11modified duration is nothing other than
  545. 26:15Macaulay duration, okay? Divided by 1
  546. 26:20plus the semiannual rate. Here it is.
  547. 26:27So in our case, the Macaulay duration
  548. 26:30was 15.84, okay? If you remember, the
  549. 26:35semiannual rate was 2.5%, so it would
  550. 26:38be 0.025, therefore the denominator
  551. 26:43will be 1 + 0.025. This result drops to
  552. 26:4915.45 if you do the calculation. Now
  553. 26:54let’s look ahead; the situation gets
  554. 26:56a little more complicated now, so pay
  555. 26:57attention. Let’s try to look at the
  556. 27:01bond’s sensitivity. So, let’s take
  557. 27:04the percentage change. By this, I mean
  558. 27:08percentage change—that is, how much
  559. 27:10the price changes—divided by the
  560. 27:13initial price itself, and you’ll see
  561. 27:16the formula, I’ll show it to you,
  562. 27:18it’s this one here. So, I want to
  563. 27:23know by what percentage my investment
  564. 27:25goes up or down as a function of the
  565. 27:28change in rates. Remember that the
  566. 27:31minus sign is mandatory; it is the
  567. 27:33golden rule of the bond balance,
  568. 27:35because if you recall, bonds and
  569. 27:36interest rates have, let’s say, an
  570. 27:38inversely proportional relationship. As
  571. 27:42for D mod, that would be the modified
  572. 27:44duration, which in our case we said is
  573. 27:4715.45. Here it is. The higher this
  574. 27:53number is, the more volatile it will be
  575. 27:55. Guys, remember that the higher the
  576. 27:58modified duration, the more volatile it
  577. 27:59will be and the more sensitive it will
  578. 28:01be to shocks from central banks or
  579. 28:03whatever happens in the market. Delta Y
  580. 28:06in this case is the change in rates,
  581. 28:09okay? In this instance, if we take a
  582. 28:12rate of 1%, okay? which in math you
  583. 28:15know we write as 0.01. When rates go up
  584. 28:20by 1%, we need to understand what
  585. 28:21happens to our bond, and I want to show
  586. 28:23you, okay? In a fairly simple way. So,
  587. 28:26let's take the coefficient, I’d call
  588. 28:28it of fragility, which is 15.45. Here
  589. 28:32it is. We multiply it by the push that
  590. 28:36rates can receive in this case, meaning
  591. 28:39by 1%, so by 0.01 and it gives me 0.15
  592. 28:46and 45. If we then apply the minus sign
  593. 28:50, okay, it means that here it becomes
  594. 28:53-0, excuse me, -0.1545. Here it is,
  595. 28:590.1545. And here it is. If I then
  596. 29:05convert it into a percentage, obviously
  597. 29:09the result is -15.45%. Okay? Because I
  598. 29:16multiply this by 100. Now let's
  599. 29:20hypothesize a shock in rates going from
  600. 29:245%to 6%, as I was telling you, so we
  601. 29:27have 5%going to 6%. Very simple. In the
  602. 29:34old situation at 5%, I was paid every
  603. 29:37semester, which means I have a 2.5%
  604. 29:40coupon here, while here I have a 3%
  605. 29:43coupon per semester. Are we on the same
  606. 29:46page? So the new discount rate to use,
  607. 29:48guys, will be 0.03. 1 + 0.03, we will
  608. 29:53put 1.03 in the denominator. Okay? I'm
  609. 29:57telling you this now so everything is
  610. 29:58clear. So, I’ll erase this here. If
  611. 30:01we take the present value now of the 60
  612. 30:02coupons, I’ll tell you right away,
  613. 30:04it's different, it comes out to 69.19.
  614. 30:09Okay? Because obviously everything
  615. 30:11changes, right? Now if we take this
  616. 30:14formula, the present value, okay, of
  617. 30:19the coupons is equal to 2.50 and I
  618. 30:26multiply it by the numerator, I put
  619. 30:291-1.03 ^ -60/0.03. What does that mean?
  620. 30:38If I take 1.03 ^ -60 it means, okay,
  621. 30:42I’ll make it fairly simple for you
  622. 30:44down here, that this 1.03 ^ -60 means,
  623. 30:49I'll make it quick for you, 1/in
  624. 30:52parentheses (1.03 ^ 60) which is equal
  625. 30:56to 0.1696 done with the calculator; we
  626. 31:04subtract it from 1, so we have 1-0.1696
  627. 31:10which is equal to 0.830. You have to
  628. 31:16keep in mind, guys, that the result
  629. 31:19coming out here of 16.96 is what a
  630. 31:22dollar is worth 30 years from now. This
  631. 31:26helps us to discount, to understand how
  632. 31:29time and the value of time impact the
  633. 31:31value of our money. Okay? So 1-0.1696
  634. 31:36gives us 0.8304. If we divide it by the
  635. 31:42new discount rate, then we have, look
  636. 31:45here, I'll erase for space reasons, we
  637. 31:47still have 0 .8304, we divide it by the
  638. 31:55new discount rate which is 0.03 gives
  639. 31:59me 27.6804. which is a discounting
  640. 32:05factor. If I multiply this factor by
  641. 32:08the coupon, I get 69.20. Okay? The
  642. 32:15second block, this is the first part of
  643. 32:17the price, we are getting to calculate
  644. 32:19the bond's price. Okay? What is the
  645. 32:22second block? We take the principal
  646. 32:25that will be returned to us in 30 years
  647. 32:27and discount it at the new discount
  648. 32:29rate, which is 6%per year and therefore
  649. 32:313%per half-year. Does that make sense?
  650. 32:34I'll clear everything here for you,
  651. 32:35we're almost done anyway, guys, don't
  652. 32:37worry, we're almost there. Uh, so, if
  653. 32:41we have the present value of the capit,
  654. 32:44we want to know the, okay, present
  655. 32:47value of the capital, we have 100/1.03
  656. 32:50^ 60. How do we solve it? This value
  657. 32:58gives us 5.8916. it would be 1.03 to
  658. 33:04the 60th power. Then we divide 100 by
  659. 33:09that number, so we get 100/5.89 and 16
  660. 33:16gives us 16.97. Okay? Now if I go and
  661. 33:23add the two blocks, we said we had
  662. 33:2669.20 + 16.97. What does that give us
  663. 33:31as a result? it gives us 86.16 or 17.
  664. 33:36Okay? So this is the new Bond price.
  665. 33:41What does that mean? If I have 86.16 as
  666. 33:46the new Bond price, guys, it means that
  667. 33:49my change in percentage terms was
  668. 33:5186.16-100, which was the previous price
  669. 33:54, minus the previous price again times
  670. 33:57100 in percentage terms, meaning my
  671. 34:00bond will drop by 13.84%. We are
  672. 34:07finished. This is the down, uh, let's
  673. 34:12say the drop of the bond when interest
  674. 34:15rates rise by 1%on a 30-year bond. Try
  675. 34:21to imagine why at a time when higher
  676. 34:23interest rates are being priced in,
  677. 34:26with central banks starting to position
  678. 34:28themselves a bit more, okay, why it
  679. 34:30becomes dangerous to have long
  680. 34:32maturities in your portfolio if you
  681. 34:34don't know macroeconomics. While the
  682. 34:37argument obviously also applies to the
  683. 34:39upside, right? Because it's wonderful
  684. 34:43to do, in my opinion, when you have
  685. 34:45macro knowledge, bond trading, because
  686. 34:48if instead I expect a 1%rate cut, I can
  687. 34:50make a 13.84%upside without any problem
  688. 34:56. Okay? So guys, keep in mind that this
  689. 34:59video might definitely be a little more
  690. 35:01difficult in terms of concepts or
  691. 35:02otherwise. I wanted to, let's say,
  692. 35:04write out all the calculations for you,
  693. 35:07but I'll put it very simply. You can
  694. 35:10just have an AI build a little model
  695. 35:12for you; tell it to make you an Excel
  696. 35:14file to calculate duration and you're
  697. 35:16set. Okay? I want to show you, if you
  698. 35:20want to understand how the curve reacts
  699. 35:22for a moment, look here. I have this
  700. 35:25Excel model, okay? Where we can see the
  701. 35:27duration and we can see the exact price
  702. 35:29. Okay, right now I have hypothesized
  703. 35:32exactly what I told you, okay? With the
  704. 35:35bond we saw earlier. So, 5%base yield,
  705. 35:395%coupon rate, 30-year maturity, and
  706. 35:43coupons, so basically two payments per
  707. 35:46year, okay? The base bond price is 100,
  708. 35:51okay? For duration estimates, I put
  709. 35:54about 15.45. So, if I go from 5%to 6%
  710. 35:58here, look, I just type 6%, and you see
  711. 36:01, the base bond price goes to 86.16.
  712. 36:06And watch now, look at the graph; I
  713. 36:08click back in here, I put 5%, look at
  714. 36:11how the curve changes because,
  715. 36:12obviously, you have the price level
  716. 36:15here too. If I put 6%back in above, see
  717. 36:19? Look, obviously the bond price has to
  718. 36:23fall, but notice that the graph below
  719. 36:25also changes. So keep in mind that all
  720. 36:29these calculations we’ve done show
  721. 36:32that, more or less, with a 1%change and
  722. 36:35a modified duration of about 16 years,
  723. 36:3815-16 years, the market impact on your
  724. 36:41portfolio is 13-14%. Very good guys, as
  725. 36:44I promised you, I made the video on
  726. 36:47duration. We'll see each other next
  727. 36:49week. I invite you to come to the BNP
  728. 36:52Paribas channel, and please, don't miss
  729. 36:55my live stream on memory products.
  730. 36:57Honestly guys, there is incredible work
  731. 37:00behind it, and there are many new
  732. 37:02things to talk about. We'll see each
  733. 37:04other in the next video. Bye everyone.
