The See-Saw Explained: What Trade-Off Is Your Portfolio Making? | Canadian Investing · How Canadian Markets Work

• 0:00
  So imagine you're looking at your monthly statement.
• 0:04
  Oh, yeah, that moment. Yeah, that moment. And
• 0:06
  the broader market is just going through one
• 0:10
  of its chaotic phases. Right, like we see every
• 0:12
  few years. Exactly. And you're fully bracing
• 0:15
  yourself for the damage on the equity side of
• 0:17
  things. You expect the stocks to look bruised.
• 0:20
  That's just the cost of doing business in the
• 0:23
  stock market. Right, you've accepted that risk.
• 0:25
  Yeah. But then your eyes drift down the page.
• 0:30
  to the conservative side of the ledger. The safe
• 0:33
  part. Right, the bond funds, the fortress, you
• 0:36
  know. And your heart just kind of sinks because
• 0:39
  that supposedly safe, boring bond fund is plummeting
• 0:44
  in value right alongside everything else. It's
• 0:47
  a genuinely terrifying moment for people. It
• 0:50
  really is. You sit there staring at the screen
• 0:52
  just wondering. how the safety net could possibly
• 0:55
  be breaking. Yeah. And the wild thing is we see
• 0:58
  this panic play out in almost every single market
• 1:01
  cycle. It's like clockwork. Right. And today
• 1:03
  we're going to solve that exact mystery. Welcome
• 1:06
  to the deep dive. We're going to spend our time
• 1:08
  today really unpacking the unyielding arithmetic
• 1:13
  of the bond market. Yes. Because Here's the puzzle,
• 1:16
  right? We're going to look at why that conservative,
• 1:20
  unglamorous part of a portfolio can suddenly
• 1:23
  drop in value even when absolutely nothing structurally
• 1:26
  wrong has happened. No companies have defaulted.
• 1:29
  Right. Nobody has missed a single payment. Everything
• 1:32
  is operating perfectly, yet the value is dropping.
• 1:35
  Exactly. And for this deep dive, we're pulling
• 1:37
  from a really rich stack of financial transcripts.
• 1:41
  Yeah, they're incredibly detailed. They really
• 1:42
  are. These sources meticulously dissect bond
• 1:46
  pricing mechanisms, the internal architecture
• 1:49
  of rolling bond funds, and crucially, the human
• 1:52
  psychology that tends to self -destruct during
• 1:54
  these market cycles. Which is so important. because
• 1:56
  it's so easy to feel overwhelmed by the sheer
• 1:59
  mechanics of fixed income. I mean, people's eyes
• 2:01
  just glaze over. Oh, totally. The jargon is a
• 2:04
  lot. Yeah. But our mission today is to deliberately
• 2:07
  slow things down. We really want to strip away
• 2:09
  the institutional jargon and give you a crystal
• 2:12
  clear understanding of the math that's just operating
• 2:15
  behind the curtain. I love that approach. Taking
• 2:18
  it slow is the best way to do this. Yeah. OK,
• 2:21
  so let's unpack this. We have to start with the
• 2:23
  foundational rule of the bond market. which honestly,
• 2:28
  it feels like a paradox the first time you encounter
• 2:30
  it. It really does feel counterintuitive, but
• 2:33
  it's the iron law of fixed income. Okay. The
• 2:36
  rule is simply this. Bond prices and bond yields
• 2:40
  move in opposite directions. Opposite directions.
• 2:43
  Always, without exception. See, usually in finance,
• 2:47
  there's a caveat, right? Like a loophole or it
• 2:49
  depends, but you're saying this is absolute.
• 2:51
  Absolute. It is mathematical gravity. And the
• 2:53
  reason for this unbending certainty, it comes
• 2:56
  down to the nature of the contract itself. The
• 2:59
  coupon, which is the actual interest payment
• 3:02
  the bond pays out, that is a contractually fixed
• 3:05
  fact. Right. It's printed right there in the
• 3:06
  document. Exactly. It's printed in the document.
• 3:09
  It doesn't care what the Federal Reserve is doing.
• 3:11
  It doesn't care about inflation. And it certainly
• 3:14
  doesn't care about the broader economy. Right.
• 3:16
  So the issuer isn't going to suddenly mail you
• 3:18
  bigger checks out of the goodness of their heart
• 3:20
  just because market conditions change. Exactly.
• 3:23
  They agreed to a number and that's the number.
• 3:25
  So if that coupon is rigid, the price of the
• 3:29
  bond itself is like the only variable left that
• 3:32
  can absorb the shock of a changing world. You
• 3:35
  nailed it. Let's walk through a very specific
• 3:38
  example from the sources to show how this mechanical
• 3:41
  adjustment happens. Let's take it nice and slow.
• 3:43
  Perfect. Imagine you hold a standard 10 -year
• 3:45
  bond. It has a face value of $1 ,000. Yeah, $1
• 3:50
  ,000. And it pays a 3 % coupon. All right, so
• 3:53
  I'm holding my 3 % bond, happily collecting my
• 3:56
  interest. That's, what, $30 a year? Yep, $30
• 3:59
  a year. You are perfectly happy. But then...
• 4:02
  The broader economic environment shifts. Market
• 4:06
  interest rates rise significantly. Now, when
• 4:09
  new comparable bonds are issued, they have to
• 4:12
  pay a 5 % coupon to attract any buyers. Right,
• 4:15
  because rates went up. Yeah. So new investors
• 4:17
  are getting 5 % for the exact same risk profile,
• 4:21
  while my older bond is stuck throwing off only
• 4:23
  3%. Exactly. So if I suddenly need liquidity,
• 4:27
  you know, and I want to sell my bond on the open
• 4:29
  market today, I'm in a terrible negotiating position.
• 4:33
  Oh, the worst. Yeah, I mean, why would anyone
• 4:36
  volunteer to buy my bond and earn three percent
• 4:38
  when they can buy a freshly minted bond paying
• 4:41
  five? They wouldn't. I mean, they absolutely
• 4:43
  wouldn't. That's the crux of it. Because your
• 4:45
  bond's coupon is permanently locked at 3%, the
• 4:49
  only lever left to pull is the price. The price
• 4:51
  has to give. You have to put your bond on sale.
• 4:54
  The price must drop. It has to drop heavily enough
• 4:56
  to make up the difference for the new buyer.
• 4:58
  Right. And what's fascinating here is that this
• 5:00
  price drop isn't some sort of market penalty.
• 5:03
  It feels like a penalty. I know. It feels terrible.
• 5:05
  But it's not a malfunction in the financial system.
• 5:09
  The discount is simply the mathematical compensation
• 5:11
  for a lower coupon. Mathematical compensation.
• 5:14
  Yes. The price falls precisely enough so that
• 5:17
  when the new buyer combines your smaller 3 %
• 5:20
  interest payments with the capital gain, they'll
• 5:22
  get at maturity. Because they bought it from
• 5:25
  me at a discount. Exactly. Because they bought
• 5:27
  it at a discount. When you combine those two
• 5:29
  things, their total return magically equals the
• 5:32
  new 5 % market rate. Wow. You know, hearing it
• 5:36
  described as two forces inextricably linked like
• 5:39
  that, it's kind of like a playground seesaw.
• 5:41
  A seesaw? Yeah, think about it. Imagine the price
• 5:43
  of the bond and the yield of the bond are the
• 5:45
  two seats on the seesaw. Okay, I'm picturing
• 5:48
  it. But that fixed coupon... the interest payment
• 5:50
  printed on the contract that is the rigid heavy
• 5:53
  wooden beam connecting them. You physically cannot
• 5:57
  move one seat without affecting the other. So
• 5:59
  if the broader market comes along and pushes
• 6:01
  the yield seat up, that rigid wooden beam mathematically
• 6:05
  forces the price seat down. That is a perfect
• 6:08
  visualization. The beam doesn't bend. It can't
• 6:10
  bend. Right. If yields go up, price goes down.
• 6:13
  The arithmetic simply demands it. But let's push
• 6:16
  on that seesaw metaphor a little bit, because
• 6:18
  I want to look at the shape of that movement.
• 6:19
  OK. If the yield seat gets pushed up 1%, the
• 6:23
  price drops. But if the yield seat gets pushed
• 6:26
  up 2%, does the price seat drop exactly twice
• 6:29
  as much? Like, is the math perfectly linear?
• 6:34
  It's actually not a straight line. It's not.
• 6:37
  No. The relationship between the price and the
• 6:39
  yield is a curve. And this introduces a really
• 6:43
  critical concept for investors to grasp. So the
• 6:45
  seesaw is curved. Exactly. It's a curved seesaw.
• 6:48
  Let's look at the actual numbers from the transcripts,
• 6:51
  going back to our specific example. The $1 ,000
• 6:53
  bond. Right. You have that $1 ,000 10 -year bond
• 6:56
  at 3%. If required, market yields rise by exactly
• 7:01
  one percentage point. So moving from 3 % to 4%.
• 7:04
  Yes, moving to 4%. The math dictates that your
• 7:07
  bonds price falls to $918 .89. $918, okay. That
• 7:13
  is an 8 .1 % drop in the price of your bond.
• 7:16
  Okay, an 8 .1 % hit for a 1 % move in rates.
• 7:20
  Right. But now, let's push it further into a
• 7:22
  more extreme environment. What if required yields
• 7:25
  rise by two full percentage points, going from
• 7:28
  3 % all the way to 5 %? Ouch. Yeah. The math
• 7:32
  shows your bond's price falling to $845 .57.
• 7:37
  I mean, 145. Which equates to a 15 .4 % total
• 7:43
  drop. Wait, let me stop you there. Yeah. A 15
• 7:45
  .4 % drop isn't double the 8 .1 % drop. Nope,
• 7:49
  it's not. Because if it were a straight line,
• 7:51
  it should be a 16 .2 % drop. Yeah. So the damage
• 7:54
  actually decelerated a little bit as rates went
• 7:56
  higher. It did. The math gets slightly less punishing
• 7:59
  the further rates rise. Wow. That subtle deceleration,
• 8:03
  that curve in the seesaw, is a concept called
• 8:06
  Convexity. Convexity. Yes. And it acts as a structural
• 8:10
  built -in cushion for the bondholder. A structural
• 8:13
  cushion. I have never heard bond math described
• 8:16
  as forgiving before. It's a very small gift,
• 8:19
  but it's real. It cushions the bleeding on the
• 8:21
  way down. But convexity is even more powerful
• 8:24
  on the way up. Really? Because of that same mathematical
• 8:27
  curve, Bond prices actually rise more when yields
• 8:31
  fall than they drop when yields rise by the exact
• 8:33
  same amount. Oh, I see. So the asymmetry actually
• 8:36
  works in your favor. That's fascinating and somewhat
• 8:39
  comforting. Yeah. But I want to pivot and address
• 8:42
  the very real emotional reaction an investor
• 8:45
  has when they look at their screen. Oh, the psychology
• 8:48
  of it all. It's so intense. It is. Because an
• 8:51
  8 % or a 15 % drop on an asset you categorized
• 8:54
  in your brain as safe is deeply alarming. Absolutely.
• 8:57
  If I log in and my statement says I've lost 15
• 9:00
  % of my bonds, my instinct is that wealth is
• 9:04
  just evaporated. Right. But if I don't sell,
• 9:08
  if I'm just holding on to that individual 10
• 9:10
  -year bond, do I actually lose that 15 %? If
• 9:13
  you are holding a single individual bond and
• 9:15
  you hold it tightly all the way to its maturity
• 9:17
  date, that terrifying price fall you see on your
• 9:20
  screen is merely a mark -to -market paper event.
• 9:23
  Just a paper event. So it's just the market telling
• 9:25
  me what I could get for it. today if I were forced
• 9:28
  to liquidate. Precisely. It's an accounting reality,
• 9:32
  but not necessarily a realized loss. You aren't
• 9:35
  selling today. Right. So at the end of those
• 9:38
  10 years, assuming no defaults, the entity that
• 9:41
  issued the bond is legally obligated to hand
• 9:44
  you back your full $1 ,000. So my principal is
• 9:48
  completely intact at the finish line. I didn't
• 9:51
  lose the 15%. Oh, right. What did I actually
• 9:53
  lose in that scenario then? You lost opportunity
• 9:56
  cost. Opportunity cost. Yeah. You were financially
• 9:58
  marooned on an island earning your original 3
• 10:01
  % for a decade, while everyone else in the market
• 10:04
  was enjoying a shiny new 5 % return. You lost
• 10:07
  the chance to earn more. But your original nominal
• 10:10
  capital, it returns to you whole. Here's where
• 10:13
  it gets really interesting though. Yeah. Because
• 10:15
  that makes perfect sense for an individual bond.
• 10:18
  But let's be honest. Almost nobody listening
• 10:20
  to this deep dive is going out and buying individual
• 10:23
  corporate or government bonds one by one. No,
• 10:25
  very few people do that. We own bond funds. We
• 10:28
  have mutual funds or ETFs sitting inside our
• 10:30
  retirement accounts. And a bond fund does not
• 10:32
  operate like an individual bond, does it? No,
• 10:35
  it operates entirely differently. And this structural
• 10:38
  difference is the root of so much investor anxiety.
• 10:41
  How so? Well, an individual bond has a fixed
• 10:44
  maturity date, right? A definitive finish line
• 10:46
  where everything snaps back to par value. But
• 10:50
  a bond fund... does not have a maturity date.
• 10:53
  Right. Because it's not a single contract. It's
• 10:55
  a massive basket of bonds. Exactly. It is a continuously
• 10:59
  rolling portfolio. The fund manager is actively
• 11:02
  buying new bonds and letting old bonds roll off
• 11:05
  to maintain a specific target profile. OK. Because
• 11:09
  this portfolio rolls on indefinitely, there is
• 11:11
  no magical calendar date in the future where
• 11:14
  the fund's price is contractually guaranteed
• 11:16
  to snap back to what you originally paid for
• 11:18
  it. Wait. OK. So if I'm holding a fund, I'm I'm
• 11:20
  not actually out there selling anything, but
• 11:22
  my monthly statement still shows a massive loss
• 11:25
  when rates rise. And you're telling me there
• 11:27
  is no maturity date to save me. That's right.
• 11:29
  Am I just permanently poorer? Like, are those
• 11:31
  losses locked in just because of the fund structure?
• 11:34
  If we connect this to the bigger picture, people
• 11:37
  mistakenly assume their bond fund acts exactly
• 11:40
  like the individual bonds inside it. Yeah, that
• 11:42
  makes sense that they would think that. But they
• 11:44
  don't. You don't have a maturity date to instantly
• 11:46
  snap your principal back to par, but you have
• 11:49
  something arguably more dynamic. You have a built
• 11:52
  -in healing mechanism. The healing mechanism.
• 11:55
  I like the sound of that. Walk me through exactly
• 11:57
  how a fund heals itself without a maturity date.
• 12:01
  Think about the mechanics of that rolling portfolio
• 12:03
  we just talked about. Bonds inside the fund are
• 12:06
  constantly maturing, or they're paying out coupons,
• 12:09
  or new cash is flowing into the fund from other
• 12:11
  investors. Right, very active. The manager takes
• 12:14
  all of that incoming cash and has to put it to
• 12:16
  work. They buy bland new bonds, and in this new
• 12:20
  environment, what are those new bonds yielding?
• 12:23
  They're yielding the new higher market rates.
• 12:27
  Exactly. The 5 % instead of the old 3%. Yes.
• 12:30
  The fund manager is continuously sweeping up
• 12:33
  those higher yields. So while a fund doesn't
• 12:36
  quote unquote mature, it is mathematically compensating
• 12:40
  for that initial terrifying price drop by building
• 12:44
  a completely new higher income stream. The portfolio
• 12:47
  is regenerating itself with better paying assets.
• 12:50
  It just takes time. How much time are we talking
• 12:52
  about? Does the math give us a timeline for the
• 12:54
  healing process? It does, actually. We use a
• 12:56
  metric called duration. Duration. Yeah. In bond
• 13:00
  math, duration isn't just a measure of price
• 13:02
  sensitivity. It's also roughly the timeline it
• 13:05
  takes for those new higher yields to mathematically
• 13:08
  offset the initial price drop caused by the rate
• 13:11
  hike. Let me make sure I'm wrapping my head around
• 13:14
  this correctly, because this is huge. Take your
• 13:17
  time. OK. I open my statement. The Federal Reserve
• 13:20
  raised rates. So my bond funds price dropped
• 13:23
  because of the seesaw effect. I don't have a
• 13:26
  maturity date to make me whole. Right. But because
• 13:30
  my fund manager is now taking all the cash generated
• 13:32
  inside the fund and buying higher yielding bonds,
• 13:35
  my fund is throwing off a much larger stream
• 13:37
  of income. Exactly. And over a period, roughly
• 13:40
  equal to the fund's duration, that higher income
• 13:43
  is methodically shoveling dirt back in to fill
• 13:47
  the hole that the price drop created. That is
• 13:50
  exactly the right way to visualize it. It's not
• 13:52
  an instant snapback. It is a slow, steady mathematical
• 13:55
  recovery fueled by compounding higher interest
• 13:58
  payments. The arithmetic is actively working
• 14:01
  to repair the damage. But this brings us to what
• 14:04
  might be the most dangerous part of this entire
• 14:06
  discussion, the psychological hassle. Oh, it's
• 14:09
  so dangerous. Because if the fund is slowly healing
• 14:12
  itself with higher yields over a matter of years,
• 14:14
  what happens when an investor looks at their
• 14:16
  statement in month two, sees the red numbers,
• 14:19
  panics, and hits the sell button halfway through
• 14:22
  that healing process? That is the ultimate behavioral
• 14:25
  trap of a rate hiking cycle. It is profoundly
• 14:28
  destructive to long term wealth, and it happens
• 14:31
  relentlessly. Let's break down the exact mechanics
• 14:33
  of that trap. Like, why is selling then so uniquely
• 14:36
  damaging? Well, when an investor sees that initial
• 14:39
  price drop on their statement, the reaction is
• 14:41
  entirely emotional. Yeah. They feel betrayed.
• 14:44
  This was supposed to be the fortress of their
• 14:46
  portfolio, and it's crumbling. It feels like
• 14:49
  a failure. It does. But if they succumb to that
• 14:51
  fear and sell their bond fund right in the middle
• 14:53
  of a rate -hacking cycle, they inflict two massive
• 14:56
  wounds on their portfolio. Two wounds. What's
• 14:58
  the first one? First, they take what was purely
• 15:01
  a temporary mark -to -market paper loss and they
• 15:04
  crystallize it. They convert it into a permanent
• 15:07
  realized loss. There is no undoing that. They
• 15:10
  make the phantom loss undeniably real. Yes. But
• 15:14
  the second wound is far worse. Really? Yeah.
• 15:17
  By exiting the fund entirely, they completely
• 15:21
  sever their connection to the new higher income
• 15:23
  stream. They cut off the healing mechanism. Exactly.
• 15:26
  They miss out on the very mathematical compensation
• 15:29
  that the market designed to make them whole again.
• 15:31
  Oh, wow. It's tragic because they endure all
• 15:34
  the agonizing pain of the price drop and then
• 15:36
  voluntarily refuse to stick around for the cure.
• 15:39
  It's the exact same psychological error people
• 15:42
  make during a stock market crash, you know, selling
• 15:44
  at the absolute bottom out of sheer terror. Exactly
• 15:47
  the same. But it feels even more insidious here
• 15:49
  because it happens in the conservative, unglamorous
• 15:51
  part of the portfolio where people least expect
• 15:54
  volatility. They are braced for it, so it catches
• 15:57
  them totally off guard. It catches them incredibly
• 16:00
  off guard. And what is absolutely vital for listeners
• 16:03
  to internalize here is that when you see those
• 16:06
  massive drops in your bond fund during a rate
• 16:09
  -hiking cycle, the financial system did not fail.
• 16:13
  See, it certainly feels like a failure to the
• 16:14
  person looking at the shrinking account balance.
• 16:16
  Of course it does. I mean, nobody likes seeing
• 16:18
  that. But structurally? The margin calls, the
• 16:22
  price adjustments, the seesaw effect, they all
• 16:25
  executed exactly as the arithmetic intended.
• 16:28
  Everything worked. Everything worked. The market
• 16:30
  priced in the new reality perfectly. The malfunction
• 16:34
  is not in the bond market. The malfunction is
• 16:36
  the investor reacting to cold hard arithmetic
• 16:39
  with irrational human fear. So what does this
• 16:42
  all mean for the person listening to this deep
• 16:44
  dive right now? Well, if you own a fixed income
• 16:46
  fund, and essentially everyone does in a diversified
• 16:48
  portfolio, you have to profoundly shift your
• 16:51
  perspective. You must understand that these sudden
• 16:54
  price drops during rate hikes are a function
• 16:55
  of gravity. It is arithmetic. They are not defaults.
• 16:58
  No. They were not corporate bankruptcies. The
• 17:01
  underlying bonds are fine. They are completely
• 17:03
  fine. They are just the seesaw adjusting to balance
• 17:07
  out the rigid wooden beam of the coupon. Exactly.
• 17:10
  Understanding this deeply is your absolute best
• 17:13
  defense against panic selling at the worst possible
• 17:16
  moment. When you know how the machine works,
• 17:19
  you can step back. Let the fund do its job and
• 17:22
  allow those higher yields to slowly heal the
• 17:24
  portfolio over its duration. This raises an important
• 17:28
  question though about the labels we use so casually
• 17:30
  in the financial industry. Oh, what do you mean?
• 17:33
  We throw around phrases like safe and risk -free
• 17:37
  all the time and investors lean heavily on those
• 17:39
  words. We do. And we anchor our entire sense
• 17:42
  of financial security to those labels. I want
• 17:44
  to leave you with a final thought to mull over
• 17:46
  regarding that specific label. Risk free. OK,
• 17:49
  let's hear it. Let's think about a 30 year government
• 17:52
  bond. If you buy that bond, it genuinely has
• 17:55
  zero default risk. Right, because the government
• 17:58
  can always print the currency if it absolutely
• 18:00
  has to. They're going to pay you back your principal.
• 18:03
  The check will undoubtedly clear. And because
• 18:05
  of that, it gets labeled risk -free. Makes sense.
• 18:07
  But imagine a scenario where you bought that
• 18:10
  30 -year bond when yields were at historic lows,
• 18:13
  say, a 1 % coupon. OK, 1%. Then over the next
• 18:17
  five years, a massive wave of inflation sweeps
• 18:19
  through the economy, and market interest rates
• 18:22
  surge to 5 % or 6%. We know exactly what happens
• 18:25
  on the seesaw then. Yeah. The price of that bond.
• 18:28
  utterly collapses on the open market. It collapses
• 18:31
  violently. And even if you refuse to sell and
• 18:34
  you hold it tightly to maturity to get your principal
• 18:37
  back, you are contractually locked into a 1 %
• 18:40
  return for three decades while inflation is running
• 18:43
  at 4 or 5%. Oh, wow. Your purchasing power, your
• 18:47
  actual ability to buy goods and services in the
• 18:50
  real world is being silently, methodically destroyed
• 18:53
  year after year after year. So risk free is actually
• 18:57
  an incredibly narrow promise. It is the narrowest
• 18:59
  of promises. Risk free only ever means free of
• 19:02
  default risk. It means the issuer won't go bankrupt.
• 19:05
  It absolutely does not protect you from losing
• 19:07
  massive amounts of purchasing power to inflation.
• 19:10
  And it does not protect you from watching the
• 19:12
  nominal market value of your asset on your screen
• 19:15
  when rates rise. The check will clear, but it
• 19:18
  might not buy you very much when you finally
• 19:20
  cash it. Exactly. That is a profound realization.
• 19:25
  It forces you to completely reevaluate what the
• 19:28
  safety net in your portfolio is actually designed
• 19:30
  to do. It really does. We have to continually
• 19:32
  question the financial labels we take for granted.
• 19:35
  Because as we've explored today, when you finally
• 19:38
  look closely at that statement, the unyielding
• 19:41
  arithmetic of the market is always operating
• 19:43
  in the background, dictating the terms, whether
• 19:46
  you understand the math or not. Arithmetic doesn't
• 19:48
  panic. And once you truly grasp the mechanics
• 19:50
  of the seesaw, neither should you. Let the arithmetic
• 19:53
  work. The next time you open that monthly statement
• 19:56
  and see your conservative funds dipping in a
• 19:58
  chaotic market, don't just scare at the red numbers.
• 20:01
  No. Picture that playground seesaw. Take a breath.
• 20:05
  Remember the rigid wooden beam of the coupon
• 20:07
  and know that the healing mechanism is already
• 20:10
  quietly at work.
