Banks Build Loan-Loss Buffers as Credit Quality Normalizes

U.S. banks are preparing investors for credit costs to move back toward historical norms after an unusually benign stretch of delinquencies and charge-offs. Under the CECL framework, lenders recognize expected lifetime losses through provisions that reduce current earnings but bolster reserves. With recent loss rates proving difficult to sustain, executives are signaling that higher provisions may reflect prudent normalization rather than evidence of broad credit deterioration.

American Banker reported on May 21, 2026, that BOK Financial, with $53.8 billion of assets, recorded just $1.9 million of net charge-offs in the quarter ended March 31, an annualized rate of 0.03%, and required no credit-loss provision. The company nevertheless retained room for normalization, revising its 2026 provision-expense guidance to $15 million-$35 million from $25 million-$45 million. CEO Stacy Kymes said the message was not that credit had worsened, but that exceptionally strong performance could not persist indefinitely.
