Junk bonds are heading for worst month since 2022 after punishing global selloff

September has delivered a sharp reversal for U.S. high-yield corporate bonds, putting the asset class on track for its worst monthly performance since 2022. The selloff has been global in scope, with riskier credit caught up in a broader wave of market volatility. Notably, the elevated yields that junk bonds offer have not been enough to cushion investors from price declines this month — a reminder that yield and total return are not the same thing.

For context, high-yield bonds sit lower on the credit-quality ladder, so they are more sensitive to shifts in risk appetite and default expectations than investment-grade debt. When volatility rises, investors typically demand a larger risk premium, which pushes prices down even when coupon payments continue.

What to watch from here: whether the volatility proves temporary or signals a lasting repricing of credit risk. Key gauges include high-yield spreads over Treasuries, fund flow data, and any signs of stress in refinancing conditions. For now, the month illustrates how quickly sentiment can turn in lower-rated credit.
