While broader investor sentiment remains constructive and overall junk spreads hover near historically low levels, fears of a stagflation shock from the Middle East conflict are souring sentiment toward the weakest global corporate borrowers, many of which binged on cheap debt during the era of ultra-low interest rates. Consequently, high yield investors now require about 6.4 percentage points of extra yield to own high-risk CCC-rated bonds over BB notes, marking a 14-month high.
This market dispersion intensified after a synchronized spike in March 2026. By May, the US HY CCC Option Adjusted Spreads (OAS) re-widened close to 1%, whereas the higher-quality BB cohort compressed below its December baseline, as investors actively rotate into higher-quality segments to shield their portfolios.
