Why hold government bonds if the yields are so low?

One of our most frequent investor questions is around our government bond holdings and the unique risks that low-interest rates present.

Government (as opposed to corporate) bonds are typically a low-risk investment. However, there plenty of doomsayers for the government bond market calling for a bond Armageddon. 

And the doomsayers are (technically) correct that if ten-year government bond rose from the current level of around 0.9% to a more typical 6% that the ten-year bond price would fall 35%. But this grossly misleading as to the true risk to investors (rather than traders) for four reasons:

Reason 1: The speed of adjustment is key

The -35% price movement in ten-year bond prices is only true if it happened overnight. 

A bond ladder is a more typical exposure for investors. Those who invest directly or (like our clients) through a separately managed account then you have far less to fear. 

An example bond ladder might have with one bond expiring every year for the next 15 years. Each year, your bonds move one year closer to maturing. Each year you take the money from the bond that matures and buy another 15-year bond. 

If bond yields move evenly from current levels to 6% over ten years, then bond investors with this strategy will make a profit. Not a great profit admittedly, only about 0.5%p.a. – but a long way away from a 35% loss. 

If the increase in interest rates was faster, say five years, then you would make a loss (if you sold the entire portfolio in five years). You would lose about 2.5%p.a. Again, not a good outcome. But not a shocking risk. 

Reason 2: Ten-year bonds are a trading strategy, not an investment

Ten-year bonds are not really an investment. You can buy a ten-year bond, but in one year you no longer own a ten-year bond: you own a nine-year bond. 

To keep a ten-year bond, you need to sell your 9.75-year bond and buy a 10.25-year bond, then wait six months and do the same thing again. And again. And again x17 more times. 

This is the action of a trader, not an investor. 

The effect on investors, who tend to have a range of different maturities is significantly different from a trader.

Reason 3: Traders take risks on bonds, investors get certainty

Traders who buy and sell rapidly, or who use leverage, or who take long/short positions have reasons to worry about significant losses on bonds.

Typical investors though buy bonds because of the certainty they provide.

When you buy a the current Australian 10-year bond, you know exactly the return you will get if you hold it to maturity. You will pay $117 today for the bond, you will get $1.25 every six months, and in May 2030 you will get back your $100. You have locked this return in.

The price of your bond will vary. But for an investor who is holding to maturity, the returns do not change. 

Reason 4: Inflation

Most bond doomsayers that are calling for the Armageddon are doing so because they are forecasting the imminent return of inflation.

One day they will be right. But the developed world has spent the last ten years (twenty in Japan), trying to create inflation. And failed. Now it is staring down the largest unemployment shock since the great depression. 

Inflation is the most significant risk facing any bond holding. But it is not a risk right now. 

So, why hold bonds at all if the yields are so low?

The real benefit of bonds is that you know already how much money you are going to lose over ten years if you hold to maturity. The answer is zero. If you buy a ten-year bond at 0.9% and hold it to maturity, you will get 0.9%. 

That is the point. Bonds give you certainty of return. What they also give you is the option to sell the bond part of the way through to take advantage if yields continue to fall.

At the moment, Australian bonds are among the highest in the developed world where credit risks are low:

Government Bonds, Risk vs Return

If Australian bond yields chase the rest of world bond yields lower, and we expect they will, the value of a typical bond ladder will increase 5-10%. As I’ve noted above, that only matters if you sell the bonds though. 

We are expecting to sell these bonds and switch into equities at some stage.

Are bonds still a safe investment?

Investors in the “V-shaped” recovery crowd should be selling bonds already. 

We are in the “lower for longer” crowd and happy to use bonds to protect us from further economic downside.

There are risks to any trade, and we have decreased our bond holdings as we have profited from falling bond yields over the last few months. 

Going forward, the risk-return equation is broadly:

  • 5-10% upside if we are right and economic conditions worsen.
  • 2.5% p.a. losses if we are dramatically wrong.

They aren’t great returns, but in a zero interest rate environment and the ability to offset losses from the stock market, there is still a reason to hold Australian Government Bonds.

  1. I dont think your downside risk really includes the worst cases

    1930s post great depression, after FDR confiscated gold, and devalued it 4x , bonds made a huge negative return relative to financial assets and gold in this period

    1940s the federal reserve capped treasury and bond yields despite rampant inflation which was a result of funding the war effort

    Japan recently if you held JGBs you got your money back at the end, and some piddling amount of interest, but you got slaughtered on currency exchange as the yen got spanked

    I think all these scenarios are very much in play in 2020-2021 (in fact there are some eerie similarities) so I think it is kind of stupid to be holding medium or long duration bonds – picking up pennies in front of the steamroller.
    If you insist on a guaranteed return why wouldn’t you just hold cash or very short duration

      In your examples you have (1) the government confiscating gold and changing the monetary system (2) a World War and (3) currency risk.
      We are not taking currency risk. You are right that I’m not investing at the moment based on a complete restructure of the monetary system or a World War being part of our likely outcomes.
      If either of the second two become likely we will re-evaluate our bond holdings. Under those scenarios, we will also re-evaluate our equity holdings.

      • I mean you’ve already seen number 1 take place: gold and equities up 30% from Mid March bottom. DXY fluctuating wildly

        So are we not already seeing this scenario starting already

        In equity and gold terms, your bond holdings have already cost you 30%

  2. All this makes good sense. But I’m reminded of that old goodie – it’s not what you don’t know that will kill you, it’s what you know that just ain’t so….

    So far, the bond dynamics have followed the rule book. Don’t overlook the possibility that the rule book may not contain all the rules.

  3. Like most economic questions this is really about the US Dollar……..so far $ 2 trillion hasn’t put a dent in it, and I will be surprised if a few trillion more can kill it. Questions of consumer inflation are moot in the face of the possible ranges of debt deflation facing our financialised economies. So many people depend on asset prices instead of income these days…..why because central banks can’t print income.
