Dial down duration—but not too much.
When facing a rising-rate environment, investors who can’t stomach too much risk should limit—but not eliminate—duration, or sensitivity to interest-rate changes.
Shortening duration can help mitigate volatility and losses as interest rates rise. Moderately trimming duration can also be an effective hedge against inflation risk.
But don’t shift to cash or drastically shorten your duration exposure, for two reasons. First, this strategy could soon have you lagging both income-generating bonds and inflation. Second, the government bonds that provide duration serve as an offset to credit- and equity-related losses—even when bond yields are low or negative.
In other words, if risk assets are the locomotive that generates high returns, duration is the track that keeps the train in line. Take away the track and you risk derailing your portfolio. (And don’t try to time increases in yield, either. Even the most seasoned bond managers can’t do that.)
Last year’s coronavirus sell-off provides important insights into the role of government bonds in an allocation. In fact, government bonds were one of the few true offsets to equity-market volatility when stocks crashed in February–March 2020 and again during the pullback in September.
On days when US stocks fell in 2020, the correlation between US Treasuries and the S&P 500 (Display, below left) remained below –0.4. And in Europe, yields on 10-year German Bunds were well into negative territory when stock markets fell in March and September. But correlations between Bunds and the MSCI Europe Index (Display, below right) became even more negative during those sell-offs, falling to around –0.5. In other words, government bonds became more defensive when defensiveness was needed most.
Correlations can be unstable. Over the last three decades, the inverse correlation between stocks and bonds has broken down several times. Most recently, in early March, rising US Treasury yields (and falling bond prices) prompted weakness in equities, resulting in a very low positive correlation between the markets. Historically, though, these episodes have been brief, and the correlation has always returned to negative territory.

Balance opposing risks.
While duration provides a buffer against credit-related losses, a healthy allocation to diverse sources of credit allows investors to participate on the upside when risk assets rally. That’s precisely why most investors need to hold both return-seeking assets and risk-mitigating assets.
In fact, among the most effective active strategies are those that combine government bonds and other interest-rate-sensitive assets with growth-oriented credit assets in a single, dynamically managed strategy.
This approach can help managers get a handle on the interaction between interest-rate and credit risks and make better decisions about which way to lean at a given moment. The ability to rebalance negatively correlated assets helps generate income and potential return while limiting the scope of drawdowns.

Lean into credit.
At this stage of the recovery, we think investors should consider tilting this balance toward credit. Risk assets such as high-yield corporates tend to outperform in a rising-rate environment, especially when inflation expectations are rising. That’s because such conditions typically go hand in hand with solid economic growth that’s supportive of credit. If that sounds familiar, it’s because that’s our environment today.
Investors with serious concerns about rising inflation might consider explicit inflation-protection strategies. But investors aren’t limited to inflation-linked bonds in developing an all-weather portfolio.
With attractive relative yields and low correlations to government bonds, many credit sectors play a defensive role in inflationary and rising-rate environments. The key is to diversify. Look for compelling risk/reward profiles across sectors and regions with varying inflation and interest-rate regimes. And be selective. Fundamentals matter.
In a world with over US$17 trillion of negative-yielding debt, pockets of the global corporate credit market stand out as a sizeable group of assets offering attractive levels of yield. Fundamentals are broadly supportive, companies have taken advantage of low rates to strengthen their liquidity buffers, and supply and demand conditions are very favorable.
Financials should benefit from an economic recovery and rising rates. As interest rates rise, so do bank margins, improving banks’ credit profiles. In Europe, for example, yields on subordinated Additional Tier 1 bonds of European banks exceed those of other European and US high-yield issuers, while their balance sheets have been bolstered by improving capital and liquidity ratios.
For a healthy yield pickup over investment-grade corporate bonds, fixed-income investors can tap US securitized assets, whose underlying cash flows come from different sources than corporate credit. In particular, we believe credit risk–transfer (CRT) securities—residential mortgage-backed bonds issued by US government-sponsored enterprises—are especially attractive. CRTs enjoy strong fundamentals, thanks to resilient demand in the US housing market. Thanks to their floating rates, CRTs offer protection against rising rates and a solid defense against inflation.
We also expect emerging-market debt to be buoyed by the weaker US dollar, continued fiscal stimulus, attractive valuations and strong investor demand for income in a low-yield environment.
What do these diverse sectors have in common? They should all benefit if vaccine rollouts continue, economies reopen and growth rebounds, prompting a tightening of credit spreads.

In this note we focus on the disparate forces that imply a higher long-term level of inflation.
