How to short government bonds

Government bond yields have been falling for 30 years. So how do you short government bonds? Simon Caufield explains.

Gold's latest bull market began around ten years ago. But government bonds have been on a tear for far longer indeed, yields have been falling (so prices have been rising) for 30 years. Today, investors are buying them for fear of deflation.

And central banks have been buying as part of quantitative easing (QE). As a result, yields are now even lower than in March 2009, when we thought the world might be ending.

Some economists argue that yields will go lower still. They point to Japan where deflation has sent ten-year government bond yields below 1%. But Japan is a case apart. It has run a huge trade surplus for decades, whereas the US and UK have trade deficits. In effect, it has been lending to the West to help us buy its exports. Also, Japanese government debt is held within Japan mostly by pension funds. That's not the case for the US or UK.

At its last meeting, the Fed hinted that it could soon launch 'QE2'. Some members of the Bank of England (BoE) Monetary Policy Committee think we need more QE here too.

It took some time for me to understand QE. But when I did, I was even more convinced of the case for shorting gilts. Suppose you sell your gilts to the BoE. It will open an account for you at the Bank. When you hand over your gilt, it makes a computer entry that shows your account holds the cash. This is money out of thin air. The BoE pays you no interest, because it wants you to spend the money, or use it to start a business, or buy stocks or bonds to finance existing businesses.

But imagine if we could all do the same as the BoE. We could use Monopoly money to buy gilts. It wouldn't take long before the bonds were worth about the same as the Monopoly money. Either bond investors will get sick of buying Western government bonds with depreciating money and dump them, or all this QE will lead to inflation, which in turn makes bonds (with their fixed payments) unattractive.

The best way to invest

But shorting bonds isn't easy. For one, you're responsible for paying the yield. So you'll lose 3% a year on a ten-year gilt if the price does not change. And unless you've got perfect timing which I don't have prices could fall further in the short run. So how do you short government bonds without losing money while you wait? I recommend the Baring Absolute Return Global Bond Trust, which invests in government bonds and currencies.

The fund has three objectives:

To return 4% per year more than three-month sterling LIBOR (a key interbank interest rate) on average over a full economic cycle.

To produce a positive return in any calendar year.

To have a low correlation with the major bond and currency indices.

Investment manager Colin Harte believes the economy will follow one of three scenarios, and he's deployed a mix of positions to make money in all three. Here they are, along with the return Harte expects to make.

Scenario 1 'US Recovery'

Western bond yields all rise and the dollar gains against the yen and euro: +23.1%.

Scenario 2: 'Anaemic Global Growth'

Bond yields fall somewhat; the dollar slides against major currencies. Commodity-backed currencies in Australia, Norway and Canada also fall: +8.7%.

Scenario 3: 'US Credibility Crisis'

Yields on long-dated UK and US bonds rise sharply. The US dollar and sterling fall against the euro, yen and commodity-backed currencies: +22.1%.

In summary, you should gain 22% if bond yields rise, while you're unlikely to lose money if bond yields fall. How is Harte positioned? He is short of government bonds in the UK, US and Europe. He is short the US dollar against the Chinese yuan, Korean won and Taiwanese dollar. And he is short the Japanese yen against the pound, dollar and Swiss franc.

Harte has delivered positive returns in each of the last five calendar years (up 1%. 4.2%, 6.5%, 1.9% and 14.8% respectively). So far this year (to 31 August), the fund is down 7.7%. I think Harte was surprised that yields fell below the levels of March 2009. But you are not buying this fund for what it has done in the past, but what it will do in future.

Obviously, we're making a trade-off here. If you know exactly when bond yields will rise, you'll make more money with a derivative. But I don't. So I'm happy to give up some upside gain to get rid of most of the downside risk. If you buy the fund using a fund supermarket, such as Hargreaves Lansdown, the 5% initial fee is cut to zero. The total expense ratio is 1.82%.
