Banking regulators require bank subsidiaries to maintain minimum average reserve balances, either in the form of vault cash or reserve balances held with central banks or other financial institutions. The amount of required reserve balances were approximately $73 million and $3.2 billion at December 31, 2020 and 2019, respectively. The Company held balances at central banks and other financial institutions of $55.4 billion and $16.2 billion at December 31, 2020 and 2019, respectively, to meet these requirements and for other purposes. These balances are included in cash and due from banks on the Consolidated Balance Sheet.
