In June, office loans accounted for 55% of the $1.05 billion in 30-day delinquent loans, an increase from 45% in May, according to Reuters. During the second quarter, Bank of America and PNC Financial Services reported significant write-offs of delinquent commercial real estate (CRE) loans, totaling hundreds of millions of dollars. M&T Bank emphasized its healthy CRE concentration amidst ongoing concerns about bank failures. Meanwhile, regional banks are beginning to see improvements in net interest income, although uncertainties regarding their exposure to the troubled CRE market persist. Bank OZK is preparing for potential credit deterioration while simultaneously expanding its CRE loan portfolio. U.S. regional banks have also increased their provisions for credit losses in response to the ongoing challenges in the commercial real estate sector, as highlighted in their second-quarter results.
