Cash and Cash Equivalents [Abstract] |
Restricted Assets | Note 2 - Restricted Assets Federal Reserve regulations require that the Bank maintain certain minimum reserve balances on hand or on deposit with the FRB, based on a percentage of transaction account deposits. In response to the COVID-19 pandemic, the Federal Reserve reduced the reserve requirement ratio to zero percent, effective March 26, 2020. Currently, the FRB has not announced plans to re-impose a reserve requirement; however, the FRB may adjust reserve requirement ratios at its sole discretion.
