The Final Rule redefined the “national rate” as the average of rates paid by all insured depository institutions and credit unions for which data is available, with rates weighted by each institution’s share of domestic deposits. The interest rate restrictions generally limit a less than well capitalized institution from soliciting deposits by offering rates that significantly exceed rates in its prevailing market. On December 15, 2020, the FDIC Board of Directors approved a Final Rule - PDF making certain revisions to the interest rate restrictions applicable to less than well capitalized institutions (as defined in Section 38 of the Federal Deposit Insurance Act), which are effective on April 1, 2021.
