Top-Performing U.S. Fixed Income Sectors of 2024: Securitized Outpaces the Agg

There was significant dispersion in returns among various fixed income sectors in 2024.

Notably, investors who hold portfolios that track the Bloomberg U.S. Aggregate Bond Index (U.S. Agg) or the Bloomberg Global Aggregate Bond Index (Global Agg) may be frustrated by their lagging performance.

In contrast, investors who adopted a multisector approach with exposure to a wide array of securitized, corporate, and sovereign fixed income assets may have generated solid positive returns in 2024, as shown in Exhibit 1.

U.S. fixed income sector returns

What performed well?

  1. Securitized credit sectors. Securitized credit had been trading cheap relative to corporates for some time, offering opportunities for attractive risk-adjusted returns. Securitized credit spreads tightened in 2024, leading to outperformance, while their inherently shorter duration shielded them from the adverse impact of rising bond yields.
  1. High yield and bank loans. Despite high-yield credit spreads trading near their historical tight levels and investor concerns around bank loan defaults, the high-yield and bank-loan sectors outperformed. Robust economic data, strong corporate fundamentals, and favorable demand-supply dynamics supported returns in these sectors.
  1. Dollar-denominated emerging markets (EM) debt. EM debt had also been trading cheap relative to corporates heading into 2024, while many developing economies are ahead of developed-world central banks in their rate-easing cycles. Standout performers included countries with improving fundamentals and ratings potential and countries in the sub-investment grade portion of the EM index.
