Bonds, huh! Yeah. What are they good for? Absolutely nuth– hang on, that’s not quite right.
Despite the exciting Bond Crash Apocalypse Now scenarios available from your local financial media outlet or multiplex cinema, bonds still have a place in the portfolio of any investor whose risk profile questionnaire doesn’t bear the name “Indiana Jones”.
But before I do, it’s worth remembering that bonds are meant to be the counter-weight to shares in a portfolio. They are the stabilising influence that tempers the turbulence. Equities are from Mars and bonds are from Venus, if you will.
- The key to (most) bonds is they aim to pay you a fixed income until a certain date, at which point you get your initial money back.2
- That is very different to equities, which offer no such certainty of income or capital returns.
- When equities crash we look to bonds to limit our losses.
- When equities underperform, we hope that bond returns can pick up the slack.
- When equity valuations are in the dumpster we rebalance from bonds to take advantage of cheap share prices.
- Bonds reduce volatility and increase our chances of getting the outcome we want.
Here’s a couple of other bond basics that will help make sense of what’s to come in the rest of this article:
Maturity refers to the length of time (usually years) before the issuer must pay back the loan that the bond represents.
The longer a bond’s maturity, the more risky it is. That’s because there’s a greater chance it will fall prey to rising interest rates and inflation.
The duration of a bond tells us two things:
1. The impact of changing interest rates on a bond. For example, a bond with a duration of seven years will lose around 7% of its market value for every 1% rise in interest rates. Equally if rates fell by 1% then the bond would gain 7%.
2. How long it will take for a bond to recover its original value as its interest payments are reinvested at a higher rate. If you hold a duration seven bond for seven years then you won’t lose your original stake.
Bonds or bond funds? Most of the characteristics described below apply equally well to individual bonds or bond funds. If in doubt, assume I’m talking about bond tracker funds and ETFs, as they are the simplest, most cost-effective way for most investors to hold fixed income assets.
Here’s a handy new-fangled infographic that lays out the bond landscape:
If you are haunted by fears of spiraling interest rates then short-term gilts are the place to be.
- They are high quality assets. The risk of the UK Government defaulting on its debts is very remote.
- Volatility is low because the maturity date of each holding is short. In other words, if interest rates rise, it won’t be long before the old bonds mature and the money is reinvested in fresh bonds that reflect the new rate.
- Returns are very low because you’re taking about as much risk as a royal nanny popping Prince George into a bubble-wrap onesie.
- Currency risk is off the table, assuming you’re an investor who spends most of their dosh in the UK4.
Who for: If you’re vulnerable to interest rate hikes, have a high fixed-income allocation, and have little need for growth then short-term gilt funds are for you (although please remember as always we’re advocating a portfolio approach with your bonds and other asset classes, not all or nothing).
This is the regular coke choice of government bond funds. It holds conventional gilts: short, long and everything in between to end up in the risk/reward sweet spot for fixed income.
Intermediates are a good choice because:
- They should be better rewarded than short-term funds. That’s because they earn a risk premium for accepting increased exposure to interest rates and inflation.
- You’ll suffer less volatility than if you were in a long-maturity fund but you’ll still grab much of the return.
- The standard advantage of guarding against stock market trauma at the cost of accepting lower returns still applies. And again, no currency risk.
How to recognise: An intermediate fund won’t call itself intermediate. It will have a very plain name: UK Gilts fund or UK Government Bond fund with no mention of any kind of timescale. Look out for an average duration of nine to 10 years in the fund factsheet.
You’re into long-maturity gilt funds because you fear deflation. Long bond funds are chock full of conventional gilts with maturities of 20 years and well beyond.
Key features are:
- They can be ravaged by spiking interest rates and inflation. If new bonds are issued that pay out at a higher rate than older existing bonds, then a 30-year bond becomes outmoded faster than last year’s smartphone. Yet it hangs about like mercury in the water supply.
- When a financial earthquake lets rip, long bonds are likely to be a safe haven. As equities, interest rates, and inflation collapse, it’s gangway for high quality, long-dated, liquid assets.
- Volatility and expected return are much higher than for their shorter bond brethren. However as bond maturities lengthen, so volatility rises faster than returns in comparison to intermediate bonds.
Who for: Young investors with 80% plus equity allocations and reasonably stable jobs have the most reason to fear deflation. The increased volatility of long bonds is barely relevant in such an aggressive portfolio.
However, long bonds are currently considered to be extremely risky given the widespread expectation that interest rates will eventually bob back to their historic norms. Under the circumstances, intermediate bonds can fulfill much the same role but will take less of a beating if rates do rise.
Economic Cassandras sometimes snicker that Western governments have no intention of ever paying off their mountainous debts. The existence of perpetual bonds is this cynicism incarnate.
‘Consols’ are a special kind of gilt issued in the distant past by the UK government that look set to pay a fixed amount of income forever. Other similar bonds include “War Loan”, which was issued in 1917 to encourage patriotic citizens to help pay for World War 1.
In theory these bonds are redeemable by a determined administration, but in practice nobody expects this to happen any time soon – where “soon” means in our lifetimes, or your grand children’s lifetime for that matter.
The origins of consols dates back to the 1700s. Their value – and hence what the government owes on them in real terms – has been utterly destroyed by the higher inflation of the 20th Century, and they now amount to a tiny proportion of the nation’s loan stock.
So while buying something that pays you an income for the rest of your life might seem akin to a perpetual motion machine, there are snags – principally caused by inflation and the time value of money.
- Perpetual bonds are essentially long-dated bonds turned up to 11. Whereas even a 40-year bond has the anchor of distant redemption date, there’s no such capital return guaranteed for a consol. This means they are entirely at the mercy of inflation and interest rate risk.
- When I say “at the mercy” I really mean it. In the late 1970s, the running yield on “2.5% consols” (and which were issued with a 2.5% coupon) flirted with 18%! This means that loyal holders who held from the 1920s saw the spending power of their consols utterly destroyed.
- On the other hand, anyone who picked up those same consols from despairing octogenarians throwing them overboard in the ’70s did very well. Since then the yield steadily fell to less than 4% by the middle of 2013, resulting in a huge capital gain over the period, as well as enormous annual income payments on their buying price.
- You can buy consols and other perpetual bonds via a stock broker, but beware their big spreads.
Who for: Doomster deflationists. Arguably they could in some other reality have a role for ordinary investors in providing steady income, but we think not at anything like today’s prices – we’d have to turn Japanese and see decades of deflation for them to be attractive. A long-dated gilt fund does a better and cheaper job at protecting against that risk for passive investors.
Want inflation-proofed government bonds? Then you want index-linked gilts (other wise known as linkers).
Here both the principal and the interest component of the bond rises and falls in line with the retail price index (RPI) measure of inflation. Plus you get a smidge more yield on top.
Inflation is the great nemesis of bonds, which makes linkers extremely useful. Indeed they are so popular in the current environment that some are priced to deliver a negative yield. In other words, you’ll pay through the nose for the safety features.
Why else should you not commit your entire bond allocation to linkers? There are a few reasons:
- Conventional (or nominal) gilts will beat linkers when inflation falls short of market expectations. Part of a nominal bond’s yield is an inflation premium. That’s why linker yields seem lower than conventional bonds. If a 10-year nominal bond yields 3% and a 10-year linker yields 0.5%, it means the market expects inflation to be 2.5%. If inflation is higher than that the linker wins. If inflation is lower then the conventional bond wins.
- If RPI inflation falls over the lifetime of the linker then you are not guaranteed a positive return from the bond.
- Hence, investors are likely to swim towards nominal gilts during crisis scenarios, not linkers.
- Linkers benefit from the same low risk traits as conventional gilts. The shorter the maturity of the bond, the smoother the ride. However, linker funds tend to be quite volatile as they have long durations – around the 18-19 year mark.
Who for? Everybody! But it’s not a good idea to place all your fixed income bets on linkers. Rampant inflation is not the only fruit.
Corporate bond funds
Corporate bonds are debt issued by companies instead of governments. They yield more than gilts because companies have an unfortunate propensity to go bust and not pay back their debt. Hence corporates offer a risk premium to compensate for the possibility of this happening, compared to the low odds of the UK government not paying up.
They’ve become popular of late as investors – who mistakenly think of bonds as blanket “safe” – scratch around for anything that seems similar to a gilt yet mysteriously offers a higher return. (The London Stock Exchange has even launched a special market to cater for retail bond investors like us).
Things to know:
- Corporate bonds are typically split into investment grade and high-yield (or junk) varieties.
- Investment grade bonds are rated AA+ to BBB- . BB+ to C is junk. Anything below that is in default.
- The fortunes of high-grade corporate bonds largely rise and fall with interest rates and inflation. Default is still a risk though.
- What’s more, many corporate bonds embed features that enable firms to repay the debt when it suits them rather than the investor.
- The higher rates of default on low-grade bonds means that they are likely to pay out less than their high yields imply.
- The volatility of corporate bonds can be deceptive. At times they appear to be as benign as government bonds. But when the markets cut up rough, corporate bonds behave more like equities, especially at the lower grades, as investors become more fearful of company defaults.
- At the very moment your bonds should be cushioning the impact of plunging equities, your corporate bonds are likely to be tanking in tandem.
- Like all bonds, interest paid by corporate bonds is taxed at higher income tax rates, not dividend income rates.
Debating point: There’s an argument that an international corporate bond fund further diversifies your portfolio, enabling you to increase expected returns without increasing risk. Many American passive investors are in ‘total bond market’ funds that include a 20-25% corporate bond slice.
But personally, I prefer asset classes to play a clearer role in my portfolio: Equities to deliver growth, and domestic government bonds to reduce risk. Corporate bonds do not strictly fulfill the defensive criteria outlined for bonds at the start of this post.
International government bonds
Adding a touch more diversification is also the reason to consider international government bonds.
However, there seems little point in devoting a portion of your bond allocation to AAA–AA rated countries that are in the same low yield boat as the UK. You’d be taking on a fair chunk of currency risk in the part of your portfolio that’s meant to offer stability.
Instead, you might consider emerging market government bond trackers that take you into the realm of sub-AA countries. If you go down this route, make sure you diversify as much as possible across countries, maturities, and currencies.
As with corporate bonds, you can expect a choppier ride from emerging market bonds. It’s probably best to carve their allocation from the equity wedge of your portfolio, rather than the low risk, fixed interest side.
Heavy bonding session
So there we have it. If you can handle equities see-sawing like Chucky after a rejection letter then bonds may be optional for you.
If not, then they have a place in your diversified portfolio regardless of the widespread conviction that interest rates must rise and that bonds will take a shoeing for a time.
Fancy grabbing some? Here’s Monevator’s take of the cheapest trackers around, including some cost-effective ways to get exposure to bonds.
Take it steady,
*Editor’s note: I think this is called “irony”, but check with Alanis Morissette.
- Please note: It’s not all or nothing! Many comments miss this point, and say bonds are “sure” to go down so why hold them. But we diversify because nothing is so sure. If government bonds do decline a little in price, it’s very likely that your equities will be more than making up the difference. And if equities crash, you’ll be glad you own some bond ballast, and of the income they pay out, too. [↩]
- Getting your money back assumes you bought when the bonds were first issued. If you (or your bond fund) buys them in the after-market, then you may get more or less back depending on the price you paid for them. [↩]
- That is, they are not linked to an inflation index. [↩]
- This is true of all domestic bond funds. [↩]
