What do rising interest rates mean for bonds?

We discuss what the rising interest rate environment in 2022 means for bond prices and your portfolio.

After interest rates in many countries were cut in response to the COVID-19 pandemic, they are back on the rise. In response to rising inflation, major economies like the U.S., England and Canada as well as New Zealand have already raised interest rates this year.

The market is currently expecting the Reserve Bank of Australia (RBA) to increase its cash rate from 0.1% to 1.75% by the end of this year and 2.30% by the end of next year.

Rising cash rates can have an impact on the value of government bonds which have a fixed interest (“coupon”) rate. The price of government bonds is determined by whether the market thinks that the coupon will be higher or lower than the expected cash rates over the period before the bond matures. If the market thinks that the coupon will be higher than the cash rate over the remaining period, then the bond will be traded at a higher price. The combination of the coupon and principal of a bond is what an investor can expect to receive at maturity (known as the “yield”).

For example, if the coupon on a bond maturing in 2 years’ time is say 1% and the cash rate is expected to be 3% over that period, then the bond is worth less than simply holding government cash and trades at roughly a 6% discount to its face value.

Over the first quarter of 2022, Australian government bonds had one of their worst quarters on record. For example, the yield on five-year government bonds rose from 1.3% to 2.6%. Since the coupon is fixed, the 1.3% increase in yield came about by the price of the bond falling by roughly 5 x 1.3% or 6.5%. The bond ETF that we invest into for clients has a similar weighted average maturity to this so it fell by around 5.8% during the quarter.

However, it might come as a surprise that when cash rates start moving higher, yields don’t always follow.

In this article, we cover:

Why are interest rate expectations rising?

Central banks usually increase their cash rate when an economy is heating up too quickly in order to curb inflation.

The economic stimulus provided by governments and central banks during the COVID-19 pandemic has led to inflation figures reaching the highest levels in decades: 3.5% in Australia and 8.5% in the U.S. This is above the average inflation target rate band of 2-3%, meaning central banks are now under pressure to start hiking rates.

While the RBA has kept cash rates at a record low 0.10% the bond market is expecting an increase in cash rates. The 10-year Australian government bond yield has more than tripled from its low of 0.8% in October 2020, up to 2.8% by the end of March 2022.

How do rising cash rates impact bond prices?

Normally, an expected rise in government cash rates will cause bond prices to fall. However, there have been numerous times in history where bonds have risen even while cash rates were rising. This has usually happened when the cash rate hike was less than what the market was expecting. Furthermore, the yield on bonds with long maturities takes into account cash rate expectations well beyond the medium-term outlook.

Oct 1999 to Aug 20004.75%6.25%5.8%Bond yields initially rose as investors factored in a higher likelihood of rate rises, but they slowed down and fell as the market thought inflation would be muted.
Apr 2006 to Mar 20085.50%7.25%8.8%While short-term yields rose, long-term bond yields did not rise as much, meaning that bond prices barely fell, and the income made up a large component of the return.
Sept 2009 to Nov 20103.00%4.75%7.1%The market priced the RBA to aggressively hike rates following the GFC, but the European debt crisis caused the RBA to slow down as anticipation for lower growth and slower inflation arose.

Should I still own bonds in my portfolio?

Yes. There are a few reasons why we believe bonds are an important part of any portfolio regardless of the interest rate environment.

  1. Removing an allocation to bonds or other defensive assets like gold would reduce the insulation in your portfolio during periods of deflation or share market volatility.
  2. Over the longer-term, if yields stay high new bonds will be issued with larger coupons. The advantage of holding an ETF that contains many bonds of different maturities is that when a bond matures, the proceeds can be reinvested into newly-issued bonds which may form a platform for capital growth.
  3. Selling bonds or changing your investment strategy in response to anticipated rate hikes is a form of market timing and unlikely to help you achieve better returns.

In Summary

While rising rates can lead to falling bond prices, it doesn’t mean you should change your investment strategy. It’s important to maintain an allocation to government bonds to help smooth your long-term portfolio returns. Stockspot also has a significant allocation to gold which has performed well, even as bonds have recently fallen.

Over the last century, despite going through both rising and falling interest rates, Australian government bonds have returned more than 6% p.a. Instead of focusing on factors outside your control (such as predicting future interest rates), take comfort that there is still merit in owning bonds due to their defensive nature and ability to provide a pattern of long-term total returns.
