US investment-grade bond funds experienced their largest weekly outflows in nearly a year, with investors pulling $5.3 billion amid rising macroeconomic uncertainty. The massive exodus reflects growing concerns about inflation, interest rate hikes, and economic growth prospects that have battered the asset class.

The outflows mark a significant shift in investor sentiment toward traditionally safe fixed-income investments. Rising Treasury yields and persistent inflation have eroded the appeal of corporate bonds, particularly those issued by blue-chip companies. Fund managers are now grappling with how to navigate an environment where the Federal Reserve's tightening cycle shows no signs of abating.

This capital flight from investment-grade bonds signals a broader market reassessment of risk. As investors seek higher returns elsewhere, the outflows could pressure bond prices further and push yields higher, creating a challenging environment for corporate borrowers and potentially tightening financial conditions across the economy.
