A recent study has highlighted significant risks in the commercial real estate (CRE) sector for US banks. The Federal Deposit Insurance Corporation (FDIC) has shown that CRE concentration risk is prevalent in banks with assets under $100 billion, while larger banks have absorbed substantial office losses. Bank OZK, in particular, faces potential trouble with $1 billion in loans, including its largest loan of $915 million, with $135 million for 'Echo Street West' in Atlanta, which is at risk of default. This has led to a major sell-off in bank stocks, with Bank OZK's outlook being downgraded. The study warns that large US banks are more exposed to commercial property than regulators appreciate, posing a blind spot risk. Additionally, small banks have increased their CRE exposure by the largest amount in 14 years, further exacerbating concerns. Moreover, the report indicates that REIT debt threatens large banks, adding another layer of risk to the banking sector.
