The upside of bond market volatility

Looking globally, volatility in the bond market has presented an attractive entry point. Not only have yields risen to appealing levels, but potential returns are notably skewed to the upside.

After recent market moves, fixed income investors have more income to cushion against further rate shocks, if uncertainty leads to increased turbulence. Conversely, if volatility subsides and yields fall back to those lower levels they have been in recent history, the upside case is increasingly compelling.

Figure 1 shows the impact of a 100 basis point (bp) move on yield levels across a range of government bond markets and maturities. Under the scenarios shown, the potential gains from a fall in yields far outweigh losses from an equivalent rise. If yields remain unchanged, income still contributes to returns.

There are three components of the total return from a bond investment. Carry measures the returns from regular interest coupons while roll-down is movement in the bond’s price, as it approaches maturity. The third is the gain or loss resulting from market forces, like credit spreads or interest rates.

Historically, bond investors were hit with a paradox. Good returns were driven by falling yields, which then provided less incentive to increase their allocation and pushed them further into riskier or less liquid asset classes. We are now in a case where the inverse is true: higher yields improve the starting income and potential return available to investors.

That income matters because it can also act as a cushion, offsetting part of the price decline should yields rise further. It also means investors do not necessarily need yields to fall to earn a positive return over the period illustrated.

The degree of protection varies by market and maturity. Longer-duration bonds are more sensitive to changes in yields, increasing both the potential gains if yields fall but also the potential losses if they rise.

Of course, yields are not guarantees of performance. Neither past performance nor mean reversion can indicate future returns. The opportunity rests on the income available today and the balance of possible outcomes, rather than an assumption that yields must return to historical averages.
 

The story of the last 30 years was that, even though sovereign debt levels rose, government borrowing costs, for the most part, fell. The backdrop is now different. Governments face challenges around security, energy and climate change, bringing about expensive and persistent borrowing needs. Higher borrowing costs make those commitments harder to finance and increase the importance of fiscal choices.

Although the US gets much of the attention, this is a global story. Debt and deficit pressures affect several developed markets, even if the amounts and circumstances differ.

Inflation remains another challenge. Central banks must balance inflation risks against economic conditions, and persistent price pressures could require policy to remain restrictive or tighten further. Investors should therefore avoid assuming that monetary policy will provide a straightforward route to lower bond yields.

For investors, higher starting income improves the return profile, but it does not remove the risks that have helped push yields higher.

Diversification is an important protection in uncertain conditions. While many problems are shared globally, central banks, inflation and credit cycles do not move in lockstep.

We have long argued for adjusting duration, country, sector and credit exposure as conditions and prices change. Figure 1 demonstrates why maturity selection matters: extending duration increases sensitivity to both favorable and adverse yield movements.

Country selection also matters. Different inflation trends, fiscal positions and monetary policy paths can create opportunities across government bond markets.

Allocating across rates and credit can reduce reliance on one macro forecast or one source of income. Credit brings a different set of considerations, including issuer strength and whether spreads adequately compensate investors for default risk.

The key to investment success will be paying attention and staying flexible through a strong multi-sector discipline.

Higher starting yields have improved the opportunity set for fixed income investors. More income provides a cushion against further yield increases, while falling yields could offer additional upside. Capturing that opportunity requires disciplined selection and responsiveness as the inflation, debt and policy outlook changes. Investors will almost certainly need to adjust their exposure to duration, credit and currency risk as conditions and prices change.

Investors should take a global perspective. Looking across major regions and sectors, down to the issuer level, can reveal opportunities and risks that a single-market view might miss and show where portfolios are being compensated for the risks they take.
