Deposit Insurance Reform Act of 2023 This bill requires the Federal Deposit Insurance Corporation (FDIC) and the National Credit Union Administration (NCUA) to establish additional levels of deposit insurance. Currently, the FDIC and NCUA insures individual accounts up to $250,000. Under the bill, FDIC and NCUA must establish insurance amounts above existing levels that are applicable to commercial deposits. An institution may elect to apply a higher insurance amount to commercial deposits.
