The Board is amending Regulation D, Reserve Requirements of Depository Institutions, to reflect the annual indexing of the reserve requirement exemption amount and the low reserve tranche for 2018. The Regulation D amendments set the amount of total reservable liabilities of each depository institution that is subject to a zero percent reserve requirement in 2018 at $16.0 million (up from $15.5 million in 2017). This amount is known as the reserve requirement exemption amount. The Regulation D amendments also set the amount of net transaction accounts at each depository institution (over the reserve requirement exemption amount) that is subject to a three percent reserve requirement in 2018 at $122.3 million (up from $115.1 million in 2017). This amount is known as the low reserve tranche. The adjustments to both of these amounts are derived using statutory formulas specified in the Federal Reserve Act. The Board is also announcing changes in two other amounts, the nonexempt deposit cutoff level and the reduced reporting limit, that are used to determine the frequency at which depository institutions must submit deposit reports.
