U.S. private-credit stress is ticking higher as Fitch Ratings put the trailing 12-month default rate at 6.3% through August 2026, edging up from July’s 6.1% and setting a new high. The gauge has remained above 6% since April, indicating persistent strain in the middle-market lending universe.

In its update, Fitch Ratings reported that August alone produced 14 default events, a jump from three in July and the largest monthly count within the current trailing-year window. The firm said 11 of those events came from first-time defaulters during the period, with three tied to repeat offenders.

Across the trailing 12 months ended in August, Fitch counted 89 distinct issuers that defaulted, generating 109 total default events. The prior month’s tally was 83 issuers and 105 events.

Default "types" skewed heavily toward amendments rather than missed payments, according to Fitch Ratings, with interest deferrals and payment-in-kind substitutions making up 47% of events in the trailing-year period. Maturity extensions executed under stress represented 41% over the same window, while uncured payment failures were listed at 8%. The remaining 4% covered bankruptcies, liquidations and restructurings that transferred control from sponsors to lenders.
