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 2025. The annual indexation of these amounts is required notwithstanding the Board's action in March 2020 of setting all reserve requirement ratios to zero. The Board is amending Regulation D to set the reserve requirement exemption amount at $37.8 million (increased from $36.1 million in 2024) and the amount of the low reserve tranche at $645.8 million (increased from $644.0 million in 2024). The adjustments to both of these amounts are derived using statutory formulas specified in the Federal Reserve Act (the "Act"). The annual indexation of the reserve requirement exemption amount and low reserve tranche is required by statute but will not affect depository institutions' reserve requirements, which will remain zero.
