18 August – 22 August 2025

Summary: 

US corporate-bond valuations have surged to their highest level in nearly 30 years as investors rush to secure elevated yields amid expectations of Federal Reserve rate cuts next month. The extra yield, or spread, over Treasuries for investment-grade bonds fell to 73 basis points on Friday—the lowest since 1998—indicating bonds have become unusually expensive. Investors are prioritizing locking in current interest rates despite economic slowdown risks and ongoing trade tensions.

High-grade bond yields have averaged over 5% in the past three years after the Fed raised rates to combat post-pandemic inflation, attracting strong demand from institutional investors, pension funds, and insurers. Some previously cautious investors, scarred by the 2022 market rout, are now rushing in, driven by “FOMO” as opportunities to secure attractive yields diminish.

The surge in demand is fueling record inflows into investment-grade bond funds, according to JPMorgan strategists, particularly as rate cuts are increasingly priced in for upcoming Federal Open Market Committee meetings. Limited new issuance adds further support, as companies delay borrowing in anticipation of lower rates. With lower supply and compressed spreads, traders find it increasingly challenging to identify profitable trades, highlighting the intensity of the current market rally.

Overall, the combination of Fed expectations, strong fund inflows, and constrained supply has driven corporate bond valuations to historic highs, reflecting both investor confidence and heightened competition for yield.
