The discount window helps ensure the basic stability of the payment system by supplying liquidity during times of systemic stress. It functions as a safety valve in relieving pressures in reserve markets by extending credit to help liquidity strains on a depository institution. To gain access to the discount window, depository institutions must have the agreements specified in operating circular 10 (OC-10) on file with the Richmond Fed and discount window loans must be secured by acceptable collateral. Our hours of operation are from 8 a.m. to 6:30 p.m. ET or until the close of Fedwire operations.
