It took me more than a year since starting this blog to get around to the topic of investing in bonds.
There are good reasons for it.
Look Mom: no bonds!
Retirement is still a long way off. As a result, I am more than happy to take on more risk in order to generate a higher long-term return.
Secondly, investing in bonds (or debt securities more broadly) is very different from investing in equities. It involves a very different approach and mindset.
Suffice it to say that in my day job, working on a debt offering is drastically different from working on an IPO.
Debt investors are far more conservative and focus on protecting the downside. In contrast, equity investors are all about growth and upside.
And finally, I just hadn’t had the time. The rabbit hole of investing can go really deep really fast – so I just hadn’t gotten around to the topic of investing in bonds.
So what has changed now? A few things, really.
Wind Of Change
It’s never too late to start pursuing financial independence – but if you start late, bonds may have a bigger role to play.
Then there’s last year’s Covid crisis, and all the talk about the way bonds have performed in the market meltdown.
It’s a no-brainer that adding bonds to your portfolio significantly reduces the risk – but has an associated impact on returns:
However, in order to understand the chart above, you need to understand the actual basics of investing in bonds.
Finally, there’s the shameless self-serving reason. The times, they are a-changing.
As much as I hate to admit it, each passing day brings me closer to the big 4-0. Can I go through another big downturn with an equity-heavy portfolio?
Sure, but I wouldn’t want to do it more than once.
I don’t often turn 40, but when I do – I write about investing in bonds
Alas, it’s time to dust off the good old bond playbook and cover off the basics of investing in bonds.
Today’s post is intended to do just that.
The Difference Between Equities And Bonds
Let’s start with a textbook definition of a bond.
Unfortunately, explaining bonds using textbook definitions isn’t always straightforward – so if that didn’t hit the spot then here’s an analogy that might be helpful.
Imagine you buy a rental property. If you choose to go with an interest-only mortgage, you can think of it as a bond.
Your interest payments are non-negotiable and at the end of the term, you’ve got to either repay the balance outstanding or take out another mortgage.
In this case, you are the borrower and the bank “owns” the bond.
As the beneficial owner of the property, you own all the equity in it. All of the excess cash flow after mortgage payments and other expenses goes to you, the equity holder.
And so if the rent – or the value of the property – goes up, the bank doesn’t get any of that benefit. It all accrues to you.
So far, so good.
But ask yourself this – is the bank really worse off in this situation, on account for missing out on all the upside?
Investing In Bonds: Risk and Return
Sure, the bank is sitting pretty in the example above.
It takes on very little risk – because it knows you will do your absolute best to make the mortgage payments.
If you don’t, the bank will send some friendly repo men over, repossess your property and sell it to make themselves whole.
That relationship may seem unfair until you consider that the bank’s returns on the mortgage are far lower than yours.
With interest rates at record lows at the moment, the bank will at best generate a 1-2% return on its investment.
The long-term direction of interest rates
You, the equity holder, stand to do much better provided you don’t totally muck it up and buy a property with a yield that’s higher than the mortgage interest rate.
(If this confused you, click here for an explanation).
If for whatever reason the price of the property quadruples, the bank won’t be any better off.
But you, the equity holder, will be sitting pretty – in compensation for all the risk that you have taken on and for making those pesky interest payments on time.
As a bond investor, you essentially take on the role of the bank. However, you won’t be funding retail mortgages (though that’s also possible).
Instead, you will be acting as a lender to large and small corporations that decided to issue debt as part of their financing strategy.
Your chance of loss is lower than that of equity holders – because if a corporation defaults on its debt, its assets will be repossessed and sold to pay the bondholders.
At the same time, your returns will also be lower.
This is why in times of economic expansions, the bonds don’t perform as well as equities. They simply don’t get to share in any of the upside.
But bring on a market downturn – and bonds hold their value pretty well.
Equity holders would need to get wiped out before bond investors lose any of their principal.
In other words, lower risk – lower return.
Different strokes for different folks
In theory, corporate bond denominations typically start at $1,000. In practice, typical corporate bond issuances have denominations of $100k.
The amount is a whopper in absolute terms but remember that the target investors are the institutional fixed-income investors who rarely cut tickets below $1m.
As a result, retail investors typically invest in the bond market through an intermediary, such as a bond fund or ETF.
Similar to stocks, an active bond fund will have a portfolio manager that will look to buy bonds with a better risk-return profile versus peers.
Passive bond funds just acquire a broad universe of bonds across geographies, issuers, and maturities and pass on the savings to investors.
For example, Vanguard’s Global Bond Index Fund invests in over 12,000 individual bonds and has an expense ratio of 0.15%.
Investing In Bonds Isn’t Without Its Risks…
While the risk profile of corporate bonds is typically safer than that of equities, they are not risk-free.
Listed below are some of the most common risks you take on when adding bonds to your portfolio.
Default risk is the risk of a bond issuer is not being able to make coupon or principal payments to bondholders.
Kind of like you missing those interest payments on your mortgage because you lost your job.
Now imagine you bought a bond with a 3% coupon and interest rates went up to 5% the following day.
You would be quite upset as every £100 invested would generate a return of only £3 per year instead of £5. This is an example of interest rate risk.
Duration risk (also known as term risk) is the risk of having your money tied up for a long period of time.
If you buy a bond with a 3% coupon and inflation rises above 3%, the value of your investment in real terms ends up being eroded.
The longer the term of the bond, the higher the likelihood of that happening.
Finally, there’s a host of other risks such as credit downgrade risk (which increases the probability of default), liquidity risk (not being able to sell the bond at a tight enough bid-ask spread), and redemption risk (which is when the bond is redeemed by the issuer).
All of the above are helpful reminders of why a passive bond investing strategy tends to be highly effective for bonds as it does for equities.
…But It Also Has A Rewarding Side To It
Having bonds in your portfolio doesn’t sound very exciting… until it does.
Typically, that happens in times of market volatility such as the one we are seeing today.
While equities plunge, bonds typically hold up in value – because they get the first claim on the assets of the borrower.
More importantly, unlike dividend payments, the coupon payments on bonds are actually non-negotiable. You get to protect the principal – and benefit from an income stream along the way.
The other, often overseen advantage of bonds is the ability to hedge against deflation.
Most of us are familiar with inflation. Well, deflation is also a thing – one that happens when the price of goods and services declines with time.
It’s a nasty one because a deflationary environment typically causes people to postpone their purchases.
Why buy a car today for £1,000 if you can get it for £950 in twelve months?
As consumer demand slows, the economy grinds to a halt, depressing equity prices… cue in Japan for the past 30 years.
In a deflationary environment, the value of your money goes up with time – and so does the value of the coupon and principal payments on the bonds that you own.
Should You Be Investing In Bonds?
For all their advantages, you may now be wondering: why invest a meaningful portion of your portfolio in instruments with a lower return profile? Has the Banker On FIRE lost a few of his marbles as he approaches old age?
Not quite (or not yet anyway).
There are three reasons you may want to sprinkle some bonds over your equity portfolio.
The first situation where it may make sense is if you are approaching retirement.
After all, you really don’t want to let the market gyrations determine when you can kiss your cubicle goodbye.
Should have added bonds to the portfolio…
Slowly increasing your allocation to bonds can smooth out the ride – and give you the peace of mind to retire even when the equity market is tanking, because your portfolio won’t be impacted as badly.
The second reason which is often overlooked is the ability to sleep well at night.
As many people discovered in March 2020, perceived and actual risk tolerance are two different concepts.
You may think you’ll be fine with a 30% reduction in the value of your portfolio.
Then a downturn hits, you lose your job, your significant other is put at risk and your tenant stops paying rent.
Wowza! Can’t blame you for being tempted to go to the mattresses 100% cash in that environment.
The best portfolio in the world won’t help you if you waver in times of crisis and sell it at the worst possible moment.
If you think there’s a chance of that happening, you may want to take a position in bonds in order to cushion the inevitable blow, even if retirement is a long way off.
The third, and most important reason, is the ability to get a free lunch.
As it turns out, it may well be possible to construct a portfolio of equities and bonds that will outperform a 100% equity portfolio.
But more on that in upcoming posts. This (soon to be old) man needs a break.
