"We provide a simple analysis of U.S. banks’ asset exposure to a recent rise in the interest rates with implications for financial stability. The U.S. banking system’s market value of assets is $2 trillion lower than suggested by their book value of assets. We show that these losses, combined with a large share of uninsured deposits at some U.S. banks can impair their stability. Even if only half of uninsured depositors decide to withdraw, almost 190 banks are at a potential risk of impairment to even insured depositors, with potentially $300 billion of insured deposits at risk. If uninsured deposit withdrawals cause even small fire sales, substantially more banks are at risk. Overall, these calculations suggest that recent declines in bank asset values significantly increased the fragility of the US banking system to uninsured depositors runs"
