Yield Explained: Do You Know Which Yield You're Chasing? | Canadian Investing · How Canadian Markets Work

• 0:00
  You know, if you buy a cup of coffee, right,
• 0:02
  the price is just, it's just the price. Right,
• 0:04
  it's fixed. Yeah, it is a single undeniable fact.
• 0:08
  Look at the board on the wall and it says $4
• 0:10
  and you hand over $4. And there's this, I don't
• 0:13
  know, this deep soothing comfort in that kind
• 0:16
  of absolute certainty. Yes, there is. We crave
• 0:20
  that. We really do. But, well, if you look at
• 0:23
  a single bond in the Canadian market at the exact
• 0:27
  same second in time, It legally has three completely
• 0:32
  different numbers quoted as its yield. Right.
• 0:34
  And so today, we're doing a deep dive into our
• 0:37
  source material to decode why the number you
• 0:39
  see advertised is, well, it's almost always a
• 0:42
  trap. It really is an illusion of certainty because,
• 0:45
  you know, we crave that linear clarity in our
• 0:48
  financial lives, like your coffee example. But
• 0:51
  the bond market just simply doesn't offer it.
• 0:53
  It's the same bond at the same second in time
• 0:56
  with three entirely different numbers. And every
• 0:59
  single one of them can legally and technically
• 1:02
  correctly be labeled as the yield. Which I mean,
• 1:05
  that feels immediately like a trap for the unwary
• 1:07
  investor, doesn't it? Oh, absolutely. Like if
• 1:09
  you hold an income fund or if you have a bond
• 1:12
  ETF in your portfolio, or even if you're just
• 1:15
  quietly trying to preserve your wealth for retirement,
• 1:19
  understanding this math is just Absolutely essential.
• 1:22
  It's critical. So we need to decode exactly how
• 1:25
  these numbers are calculated and, more importantly,
• 1:28
  why they even exist in the first place. Yeah,
• 1:30
  let's build it from the ground up. Okay, so let's
• 1:33
  establish the foundation first. Yeah. What is
• 1:35
  the very first metric we encounter when we look
• 1:38
  at a bond? Right, so the first one is the coupon
• 1:40
  rate. The coupon rate, okay. Yeah. And this is
• 1:43
  the simplest metric. It's also the most rigid.
• 1:46
  It's just a fixed percentage of the bond's original
• 1:49
  face value. OK. Which is also known as its par
• 1:52
  value. Par value, right. And in the Canadian
• 1:55
  market, what is that usually? In Canada, that
• 1:57
  par value is typically $1 ,000. $1 ,000. Exactly.
• 2:01
  So if a bond has, let's say, a 5 % coupon rate,
• 2:05
  it pays you $50 a year. Because 5 % of $1 ,000
• 2:09
  is $50. Right. And that is a permanent contractual
• 2:12
  fact about the bond. It tells you the absolute
• 2:15
  cash flow. It does not, however, tell you anything
• 2:18
  about your actual return. Because it completely
• 2:21
  ignores the reality of the secondary market,
• 2:24
  right? It's just a percentage of that original
• 2:27
  $1 ,000 face value, regardless of what I actually
• 2:31
  paid to acquire the bond today. Yes. Like, I
• 2:33
  could have bought it on sale for, say, $800.
• 2:36
  Or I could have wildly overpaid it $1 ,200. And
• 2:40
  the coupon rate remains... Well, it's just perfectly
• 2:43
  indifferent to my reality. It doesn't care at
• 2:45
  all. No. The coupon rate only cares about the
• 2:48
  contract, not the market. Right. Right. Which
• 2:50
  brings us to the second number. Right. Right.
• 2:53
  A metric that is actually designed to address
• 2:55
  that very blind spot. OK. And that's the current
• 2:57
  yield. Current yield. So how does that one work?
• 3:00
  So this calculation takes the annual coupon payment,
• 3:04
  right, that $50, and it divides it by the current
• 3:06
  market price of the bond. Ah. So it tells you
• 3:09
  the cash income you're generating. relative to
• 3:11
  the capital you actually deployed today. So it
• 3:14
  accounts for the purchase price? Exactly. Okay,
• 3:16
  well, that's a step closer to reality, I suppose.
• 3:19
  It gives me a sense of my immediate return on
• 3:22
  investment. Right, it does. But there is a third
• 3:25
  metric. Of course there is. And this is the one
• 3:27
  that actually completes the picture. Okay, lay
• 3:29
  it on me. It's called yield to maturity, or you'll
• 3:32
  often see it as YTM. YTO. Yeah. And this is the
• 3:36
  total annualized return you will experience if
• 3:39
  you buy the bond at today's price and hold it
• 3:42
  all the way to its maturity date. OK, all the
• 3:44
  way to the end. All the way to the end. It counts
• 3:46
  every single coupon payment you'll receive. Plus,
• 3:50
  it accounts for the principal repayment at the
• 3:52
  very end. OK. So it blends your cash flow with
• 3:55
  your capital gain or your capital loss over the
• 3:59
  entire life span of the asset. You know, it feels
• 4:01
  very much like the mechanics of buying a vehicle.
• 4:04
  Oh, how so? Well, think about it. The coupon
• 4:08
  rate is simply the sticker price printed on the
• 4:11
  window at the dealership. OK, yeah. It's just
• 4:14
  a stated manufacturer fact. Right. And then the
• 4:17
  current yield, well, that's your monthly car
• 4:19
  payment. It tells you your immediate cash flow
• 4:21
  right now based on the price you actually negotiated.
• 4:23
  But the yield to maturity, That is the total
• 4:26
  cost of ownership over the full life of the vehicle.
• 4:29
  You know, factoring in your insurance, the depreciation,
• 4:32
  the eventual resale value, just everything. That
• 4:35
  is actually a remarkably precise analogy. Oh,
• 4:39
  thanks. Yeah, because the total cost of ownership
• 4:42
  is really the only metric that tells you the
• 4:44
  complete truth of the transaction. Right. And
• 4:46
  yield to maturity is the only number that gives
• 4:49
  you that total mathematical picture of what you're
• 4:52
  surrendering today and what you're receiving
• 4:54
  in the future. But if yield to maturity is the
• 4:57
  only complete truth, why do we even tolerate
• 4:59
  the existence of three different metrics for
• 5:01
  the exact same financial instrument? It's a fair
• 5:03
  question. It just feels almost intentionally
• 5:05
  opaque, you know? Like, if I'm an everyday retail
• 5:08
  investor, looking at three different yields for
• 5:10
  the same bond is just a recipe for confusion.
• 5:13
  Yeah, it's entirely fair to feel frustrated by
• 5:16
  the ambiguity. I get it. but it isn't an intentional
• 5:19
  deception. No, it's more of a reflection of the
• 5:22
  fact that different market participants are trying
• 5:24
  to solve entirely different mathematical problems.
• 5:27
  Okay, like what? Well, consider a pension fund
• 5:30
  manager with 30 -year liabilities. Right. They
• 5:33
  care almost exclusively about yield to maturity.
• 5:36
  They need the complete, compound mathematical
• 5:39
  truth to ensure they can actually pay out pensions
• 5:42
  decades from now. That makes sense. Right. But
• 5:45
  a retiree living on a fixed income Well, they
• 5:48
  might be highly focused on current yield. Oh,
• 5:50
  because they need the cash now. Exactly. Their
• 5:53
  immediate pressing problem is generating enough
• 5:56
  cash flow this month to pay for their groceries.
• 5:58
  Oh, I see. Yeah, so they might accept a mathematically
• 6:01
  suboptimal total return if it guarantees their
• 6:05
  current income stream. The metrics simply answer
• 6:08
  different questions. The market provides different
• 6:10
  lenses for different needs. OK, I understand
• 6:12
  the logic. But to truly grasp why relying on
• 6:16
  the wrong lens is so dangerous, I think we need
• 6:19
  to move away from abstract theory. We got an
• 6:21
  idea. Yeah. Let's look at the mechanics in action.
• 6:23
  I want to walk through the exact arithmetic of
• 6:26
  a discount bond based on the sources. OK, let's
• 6:29
  do it slowly, because the math here is where
• 6:31
  people get tripped up. Right. So consider a five
• 6:34
  -year bond. It has a 5 % coupon. And it has the
• 6:39
  standard $1 ,000 face value we talked about.
• 6:41
  OK, so $50 a year. Right. But let's consider
• 6:44
  the broader economy. Let's assume the central
• 6:46
  bank has recently raised interest rates. OK.
• 6:49
  So brand new bonds being issued today are now
• 6:51
  paying, say, 7%. Right. And because new bonds
• 6:54
  are paying 7%, my older bond, which only pays
• 6:57
  5%, is suddenly far less attractive. Exactly.
• 7:00
  Because, I mean, no rational investor is going
• 7:03
  to pay me a full $1 ,000 for my 5 % bond when
• 7:06
  they can just buy a brand new one paying 7%.
• 7:09
  Precisely. The mechanism of the market forces
• 7:11
  an adjustment. To make your 5 % bond competitive,
• 7:14
  the price has to drop. You have to put it on
• 7:17
  sale. You have to put it on sale. So let's say
• 7:19
  today, you can buy this specific bond at a discount
• 7:23
  for exactly $900. Okay, let's run the numbers
• 7:26
  on that exact scenario step by step. First, the
• 7:29
  coupon rate. The contract remains unchanged.
• 7:33
  It is 5 % of the original $1 ,000 face value,
• 7:36
  so it pays $50 a year. regardless of the fact
• 7:39
  that the bond is on sale for $900. Correct. Now,
• 7:42
  let's calculate the current yield. OK. You take
• 7:45
  that $50 of annual cash flow and you divide it
• 7:48
  by the $900 you actually paid to acquire the
• 7:50
  bond. OK. So 50 divided by 900, that gives us
• 7:53
  a current yield of exactly 5 .56%. Right. And
• 7:58
  looking at that, 5 .56 % is noticeably better
• 8:02
  than the original 5 % coupon. It feels like a
• 8:05
  solid deal. It does feel solid. But there's a
• 8:08
  massive mechanical blind spot in that calculation.
• 8:11
  OK, what am I missing? Well, current yield completely
• 8:14
  ignores what is destined to happen in year five.
• 8:17
  Year five, the maturity date. Right. You only
• 8:20
  paid $900 for this bond today. But when it matures,
• 8:24
  the issuer does not hand you back $900. Ooh.
• 8:28
  They are legally obligated to return the full
• 8:30
  $1 ,000 face value. I see the mechanism. I am
• 8:36
  receiving a guaranteed $100 capital gain at the
• 8:40
  very end of this timeline. Yes, you are. And
• 8:43
  that current yield calculation of 5 .56 % is
• 8:46
  just entirely blind to it. It is entirely blind.
• 8:48
  It pretends that $100 capital gain simply does
• 8:51
  not exist. Wow. Yeah. But if we calculate the
• 8:55
  yield to maturity, we account for those $50 annual
• 8:58
  coupons plus that $100 capital gain plus the
• 9:02
  effect of compound interest spread out over the
• 9:04
  five -year period. OK, what does that come out
• 9:06
  to? When you run that comprehensive math, the
• 9:09
  yield to maturity is actually 7 .47%. Let's just
• 9:12
  pause and reflect on the distance between those
• 9:14
  numbers for a second. A 5 % coupon, a 5 .56 %
• 9:19
  current yield, and a 7 .47 % yield to maturity.
• 9:23
  That is, well, that's a remarkably widespread.
• 9:26
  It really is. If I only look at the current yield
• 9:29
  on a discount bond, It drastically understates
• 9:32
  my actual return. Like I might look at five and
• 9:34
  a half percent and decide to pass completely
• 9:37
  on a way that the mathematical reality is closer
• 9:39
  to seven and a half. Precisely. On a discount
• 9:42
  bond, current yield quietly obscures your capital
• 9:46
  gain. The total return is much stronger than
• 9:49
  the immediate cash flow suggests. Which naturally
• 9:52
  leads to the inverse scenario, doesn't it? Oh,
• 9:54
  yes. Because if a discount bond artificially
• 9:57
  flatters my position by hiding a gain, what happens
• 10:00
  if I overpay for a bond? Right. Because intuitively
• 10:03
  that feels like walking into a trap. Let's look
• 10:06
  at premium bonds. It is a trap and an exceptionally
• 10:09
  common one. Let's consider a different bond.
• 10:11
  This one has an extremely generous 8 % coupon.
• 10:14
  Nice. Right. And it also has five years left
• 10:16
  to maturity. But let's reverse the economic scenario.
• 10:20
  Let's assume interest rates in the broader economy
• 10:22
  have dropped significantly. OK. Down to perhaps
• 10:25
  three or four percent. So an eight percent coupon
• 10:27
  is suddenly incredibly attractive. Exactly. Investors
• 10:30
  are going to swarm this bond because they just
• 10:33
  can't find that kind of yield anywhere else in
• 10:35
  the current market. And that massive demand is
• 10:38
  going to drive the price of the bond up. Exactly.
• 10:40
  The demand pushes the price far above the original
• 10:44
  one thousand dollar par value. Right. So it's
• 10:47
  currently priced at a premium, let's say $1 ,150.
• 10:51
  OK, let's calculate the current yield on that
• 10:54
  premium price. So the bond pays $80 a year. I
• 10:58
  divide that $80 by my purchase price of $1 ,150.
• 11:03
  And that gives me a current yield of nearly 7%.
• 11:06
  And to an everyday investor scrolling through
• 11:09
  a brokerage application, locking in a nearly
• 11:13
  7 % yield in a low interest rate environment,
• 11:16
  Well, that looks incredibly appealing. It looks
• 11:18
  like a phenomenal source of stable income. Yeah.
• 11:21
  But here is the mechanical trap. Current yield
• 11:23
  is blinding you to the inevitable conclusion.
• 11:26
  At maturity, in five years, you do not get your
• 11:30
  $1 ,150 back. Right. The issuer is only obligated
• 11:34
  to return the $1 ,000 face value. Which means
• 11:37
  I am going to suffer a guaranteed mathematically
• 11:40
  certain loss of $150 on my principal. Yes. You
• 11:45
  have a built -in capital loss from the very seconds
• 11:48
  you purchase the bond. And the current yield
• 11:51
  completely ignores it, thereby drastically overstating
• 11:54
  your true return. Okay. When you factor in that
• 11:57
  $150 evaporation of your principal, your actual
• 12:01
  yield to maturity is significantly lower than
• 12:03
  that appealing 7%. So it's a mirage. It is. This
• 12:07
  is why premium bonds are the dangerous direction.
• 12:09
  A high -coupon bond trading at a premium shows
• 12:13
  a beautiful current yield while quietly masking
• 12:16
  a built -in capital loss. So wait, that 7 % yield
• 12:19
  might literally just be the issuer paying me
• 12:21
  back with my own money? Essentially, yes. Just
• 12:24
  in small monthly installments while inviting
• 12:26
  me to politely call it a return? That is the
• 12:28
  most structurally honest description possible.
• 12:31
  They are handing you your own capital back, labeling
• 12:35
  it as yield, and relying on the fact that most
• 12:37
  investors will not notice their principal quietly
• 12:41
  eroding. That is genuinely unsettling. Yeah.
• 12:44
  And I think it moves us perfectly from the mechanics
• 12:47
  of individual bonds to how this exact math is
• 12:50
  utilized in retail funds. Yes. Let's talk about
• 12:53
  funds. Because fund managers understand this
• 12:56
  math intimately. How do funds use these numbers
• 13:00
  to market themselves to everyday investors? They
• 13:02
  use it very effectively. And this brings us to
• 13:04
  what we call the distribution yield trap. The
• 13:07
  distribution yield trap. When you look at a bond
• 13:10
  mutual fund or an exchange traded fund, they
• 13:12
  will prominently publish something called a distribution
• 13:15
  yield. And this is simply a measure of the cash
• 13:17
  they're paying out to unit holders right now.
• 13:20
  But buried deeper in the fund documents, they
• 13:23
  will also publish the yield to maturity of the
• 13:25
  underlying bonds they actually hold. And if those
• 13:27
  two numbers are significantly different, we have
• 13:29
  a structural reality that requires our attention.
• 13:32
  We do. If a fund's distribution yield is much
• 13:36
  higher than the yield to maturity of the bonds
• 13:38
  it holds in its portfolio, that extra money has
• 13:41
  to come from somewhere. Right. They can't just
• 13:43
  invent money. Exactly. The fund cannot magically
• 13:46
  generate more interest than its underlying bonds
• 13:49
  are paying. Yeah. So a significant portion of
• 13:52
  what you're receiving in that high distribution
• 13:54
  is likely what is categorized as return of capital,
• 13:58
  or ROC. Let's unpack the mechanics of return
• 14:01
  of capital because the phrase itself, I mean,
• 14:04
  it sounds entirely benign. It does. It just sounds
• 14:07
  like my original money is coming safely home
• 14:09
  to me. It sounds benign, but it carries profound
• 14:12
  tax implications, particularly in the Canadian
• 14:15
  context. OK, how so? Well, return of capital
• 14:17
  is not immediate income. It's the fund literally
• 14:20
  liquidating a portion of your original investment
• 14:23
  and handing it back to you. Right. And because
• 14:25
  it's your own money being returned, it is not
• 14:27
  taxed in the year you receive it. Which, on the
• 14:29
  surface, feels like a benefit. Tax -free cash
• 14:31
  flow is always appealing. It feels like a benefit
• 14:34
  in the moment. Yeah. But the tax system is meticulous,
• 14:36
  and it never forgets. Oh, boy. Every single dollar
• 14:39
  of return of capital you receive quietly reduces
• 14:43
  what is called your adjusted cost base, your
• 14:45
  ACB. The adjusted cost base. the foundational
• 14:49
  number the government uses to calculate how much
• 14:51
  profit I made when I eventually sell the front,
• 14:53
  right? Exactly. Let's walk through the mechanism.
• 14:55
  Okay. Imagine you buy a fund at $20 a unit. Over
• 14:59
  a few years, they pay you out $2 in return of
• 15:02
  capital. Mm -hmm. You didn't pay tax on that
• 15:05
  $2 when it arrived, but your adjusted cost base
• 15:08
  drops from $20 down to $18. So it is essentially
• 15:12
  like taking a cash advance on your own estate.
• 15:14
  You feel wealthy today collecting this tax -free
• 15:17
  yield, but the final bill remains exactly the
• 15:20
  same. It just comes due later. Yes. Because even
• 15:23
  if the fund's market price never moved a single
• 15:25
  cent, like even if it's still trading at exactly
• 15:27
  $20, if I decide to sell it, the government looks
• 15:30
  at my lowered cost base of $18 and declares that
• 15:33
  I made a $2 capital gain per unit. Precisely.
• 15:36
  The mechanical reality of return of capital is
• 15:39
  that it defers your tax bill, but it also converts
• 15:42
  it. By lowering your adjusted cost base, it triggers
• 15:45
  a larger capital gains tax liability when you
• 15:49
  eventually sell your position. You are essentially
• 15:51
  borrowing from your future self to fund a high
• 15:54
  yield today. So if an investor doesn't understand
• 15:57
  the distance between distribution yield and yield
• 16:00
  to maturity, they could be buying a fund in a
• 16:02
  non -registered account. enjoying these massive
• 16:05
  monthly distributions and be completely unaware
• 16:08
  that they are steadily building a deferred capital
• 16:11
  gains liability. It is a quiet accumulation of
• 16:14
  future tax debt. And there's a second layer to
• 16:17
  the tax illusion that we must address. OK, what's
• 16:19
  that? When you see a yield to maturity quoted
• 16:21
  on any platform, you have to remember that it
• 16:24
  is a before tax, before cost number. And under
• 16:27
  Canadian taxation, interest income from bonds
• 16:29
  is treated very differently than capital gains
• 16:31
  or eligible dividends. It is treated far less
• 16:34
  favorably. Right. Interest income is fully taxable
• 16:37
  at your highest marginal tax rate. There is no
• 16:40
  preferred treatment. Yeah. So if you're looking
• 16:42
  at a bond yielding 5 % in a non -registered account,
• 16:46
  your actual realized return after the government
• 16:49
  takes its required share is meaningfully lower.
• 16:52
  The quoted yield presents an illusion of a gross
• 16:55
  return. your net mathematical reality is much
• 16:58
  tighter. So we're really dissecting the actual
• 17:01
  plumbing of these financial products today. We've
• 17:03
  covered the big three yields, right? The coupon
• 17:06
  rate, the current yield, and the yield to maturity.
• 17:09
  We have navigated the mechanics of discount and
• 17:11
  premium bonds. And we've outlined how return
• 17:14
  of capital in retail funds slowly erodes your
• 17:16
  adjusted cost base. But there is one final caveat
• 17:20
  from the sources that we need to explore. OK.
• 17:22
  A scenario where even yield to maturity, which
• 17:25
  we set as the gold standard metric is not the
• 17:28
  final word. What happens if the bond contract
• 17:30
  includes an escape hatch for the borrower? Ah,
• 17:33
  you're referring to callable bonds. Callable
• 17:36
  bonds, yes. Many corporate bonds have a specific
• 17:38
  feature embedded in the legal contract that allows
• 17:41
  the issuer to redeem or call the bond. back before
• 17:45
  its official maturity date. They hand you your
• 17:48
  principal back early, and they completely stop
• 17:50
  paying you interest. Let's examine the motivation
• 17:52
  there. Why would a corporation go through the
• 17:55
  immense expense and effort of issuing a 10 -year
• 17:58
  bond only to cancel it after four years? Because
• 18:00
  the broader economic environment changed. Specifically,
• 18:04
  interest rates fell. If a corporation issues
• 18:06
  a bond paying 6 % and three years later, Market
• 18:10
  rates have dropped so significantly that they
• 18:13
  could borrow brand new money at 4%. They're going
• 18:16
  to want the cheaper money. Exactly. They will
• 18:18
  call your 6 % bond, pay off the principal, and
• 18:21
  refinance their debt at the cheaper 4 % rate.
• 18:24
  Yeah, that makes sense for them. It's important
• 18:27
  to remember a foundational rule of finance. If
• 18:29
  an option exists in a financial contract, it
• 18:32
  exists for the exclusive benefit of the party
• 18:35
  who holds the option. In this case, the corporate
• 18:38
  issuer. Right. They will only exercise that option
• 18:41
  when it hurts your return and helps their balance
• 18:44
  sheet. So if I purchase a callable bond, I cannot
• 18:48
  actually rely on the yield -to -maturity calculation
• 18:51
  because the bond might never live to see its
• 18:54
  maturity date. Exactly. This is why the industry
• 18:57
  utilizes a metric called yield -to -worst or
• 18:59
  YTW. Yield -to -worst, okay. The calculation
• 19:02
  requires you to model two futures. You calculate
• 19:05
  the yield -to -maturity assuming the bond lives
• 19:07
  its full uninterrupted life. Okay. Then you calculate
• 19:11
  the yield -to -call assuming the bond is called
• 19:13
  away from you at the absolute earliest possible
• 19:15
  date permitted by the contract. Right. Prudent
• 19:18
  practice dictates that you always, always rely
• 19:21
  on the lower of those two numbers. Because you
• 19:23
  have to mathematically assume the worst case
• 19:25
  scenario. Yes. Because the issuer is acting rationally,
• 19:30
  strictly in their own financial self -interest.
• 19:32
  Yield to worst. You essentially assume the market
• 19:34
  will execute whatever sequence of events is least
• 19:37
  profitable for you. That's right. That is a very
• 19:40
  safely cynical but highly necessary way to navigate
• 19:43
  the bond market. It really is the only mathematical
• 19:45
  framework that actually protects your capital.
• 19:47
  Let's step back and just sort of survey the landscape
• 19:50
  we've mapped today. There's a lot. We have decoded
• 19:53
  the math behind bond yields. We've established
• 19:56
  that an investor must never trust the solitary
• 19:58
  word yield without immediately asking, which
• 20:01
  yield? We have observed how current yield artificially
• 20:05
  flatters premium bonds, quietly masking a guaranteed
• 20:08
  loss of principal. And we've detailed how return
• 20:11
  of capital distributions gradually lower an investor's
• 20:15
  adjusted cost space, converting current income
• 20:17
  into a deferred capital gains tax liability.
• 20:20
  It is a landscape that demands extreme precision
• 20:23
  and patience from the investor. You cannot simply
• 20:26
  glance at a percentage sign on a screen and allocate
• 20:29
  your capital safely. No, you can't. But as we
• 20:31
  close this analysis, we want to leave the listener
• 20:33
  with one final slightly provocative thought to
• 20:36
  consider from our deep dive. OK. We spent this
• 20:38
  entire time establishing that yield to maturity
• 20:40
  is the definitive complete picture. It's the
• 20:42
  metric the professionals use. Right. But if we
• 20:45
  look closely at the mechanics, even yield to
• 20:47
  maturity contains a deeply embedded structural
• 20:50
  flaw. It does. A deeply embedded mathematical
• 20:54
  assumption. Yeah. Yield to maturity operates
• 20:58
  on the strict premise that you will take every
• 21:01
  single coupon payment you receive over the entire
• 21:04
  life of the bond, and you will instantly reinvest
• 21:07
  it at that exact same YTM rate. Let me make sure
• 21:10
  the mechanics of that assumption are perfectly
• 21:12
  clear. Okay. If I buy a bond with a 7 % yield
• 21:16
  to maturity, The underlying math simply assumes
• 21:20
  that when my $50 coupon arrives in the mail,
• 21:23
  I can instantly find another investment vehicle
• 21:26
  offering exactly 7 % and park that $50 there.
• 21:29
  Yes. That frictionless reinvestment is permanently
• 21:32
  baked into the calculus. Wow. But consider the
• 21:35
  reality of the broader economy. What if market
• 21:37
  conditions shift? What if interest rates plummet
• 21:40
  the literal day after you purchase your bond?
• 21:43
  Well, then I can't reinvest my future coupons
• 21:45
  at 7%. The market might only be offering 3%.
• 21:47
  Precisely. You'll be forced to reinvest those
• 21:49
  coupons at significantly lower prevailing rates.
• 21:52
  This is known as reinvestment risk. And because
• 21:55
  of that friction, your real realized return when
• 21:59
  the bond finally matures, will actually fall
• 22:01
  short of that mathematically perfect yield to
• 22:04
  maturity you were quoted on day one. So even
• 22:06
  the gold standard metric is an illusion. In a
• 22:09
  way, yes. It's based on the assumption of perfectly
• 22:11
  static market conditions, which raises the ultimate
• 22:15
  question, right? If the math fundamentally assumes
• 22:18
  a future that hasn't happened yet, can you ever
• 22:21
  truly know your exact realized return until the
• 22:24
  very day the bond matures? You cannot. The certainty
• 22:27
  we all crave, that clean absolute price tag on
• 22:30
  the cup of coffee we discussed at the very beginning,
• 22:32
  it simply does not exist in this space. When
• 22:35
  you look at a bond yield, you are not looking
• 22:37
  at a fixed reality. You are buying a highly educated
• 22:40
  probability quietly masked behind a very precise
• 22:43
  looking number. The price tag is an illusion.
• 22:46
  You acquire the asset, you perform the meticulous
• 22:49
  math, but the actual final reality of your return
• 22:52
  remains perfectly obscured until the very last
• 22:54
  day. It's not a fixed number, it's a constantly
• 22:57
  living equation.
