Investors are increasingly gravitating toward shorter-duration corporate bonds, aiming to lock in elevated yields while minimizing exposure to volatility in interest rates and market disruptions. This approach has proven successful: over the past month, bonds with maturities of five years or less have outperformed the broader Bloomberg Euro Investment Grade Corporate Bond Index, as longer-duration securities struggled. A similar trend is evident in the U.S. market.

Given the steady income offered by short-term bonds, the incremental gains from pursuing slightly higher yields further along the yield curve are hardly worth the effort. Jim Caron, Chief Investment Officer at Morgan Stanley Investment Management, notes, "Duration is the factor currently weighing on returns." He is constructing a portfolio of high-quality, short-duration bonds that "reduces some interest rate sensitivity without sacrificing yield."

This month, escalating conflict between the U.S. and Iran has stoked inflation fears, dragging down prices of U.S. Treasuries, the benchmark asset, and squeezing investment returns. On Wednesday, the Federal Reserve paused its rate hikes, but markets plunged anew as investors bet this merely delays an inevitable tightening. The 30-year U.S. Treasury bond saw a sharp price decline. The European Central Bank also held rates steady last week, though policymakers have signaled a potential further tightening as early as September.

By shifting to shorter-duration credit, investors can mitigate the impact of dramatic swings in interest rate expectations. Longer-duration debt is particularly sensitive to rate increases, as its prices must fall more steeply to compensate buyers for the lower coupon payments. In a report citing EPFR data, Bank of America strategists noted that funds focused on intermediate and short-term maturities continued to attract fresh inflows last week, even amid overall market outflows.

Short-term bonds typically experience less price volatility because they are closer to maturity. As the maturity date approaches, their prices naturally converge toward face value, helping buffer portfolios against fluctuations in interest rates and credit spreads. Over the past month, bonds with maturities of less than one year have posted near-flat total returns, while the Bloomberg index declined 0.9%. In contrast, bonds with maturities of 10 years or more have fallen more than 2.9%.

The yield curve is flattening, and there is little incentive for investors to take on the extra risk of holding longer durations. For example, the yield pickup from a 3-year bond to a 9-year bond is only 67 basis points, according to compiled data. Rufaro Chiriseri, Head of European Fixed Income at RBC Wealth Management, comments, "Stretching too far along the duration curve doesn't offer much additional yield, so you're actually better off with shorter durations while still capturing attractive returns. We are quite comfortable with a shorter-duration stance and are even willing to take on slightly lower credit quality within the investment-grade space."

Some investors believe that higher forward yields are not worth the associated risk. By reducing duration exposure, investors can improve their holdings' "credit breakeven" point, providing a larger buffer when credit spreads widen or interest rates move. With spreads currently near their lowest levels since 2008, asset managers see little room for further tightening. For now, the additional risk of buying longer-duration bonds exposes investors to potential losses as markets continue to price in further central bank rate hikes.

Mark Haefele, Chief Investment Officer at UBS Global Wealth Management, states, "While central banks may remain cautious in the short term, we expect inflation pressures to ease over the next 12 months and recommend locking in current high yields, particularly in high-quality, medium-to-short-term bonds."
