In The Eurozone
In the eurozone the discount window is called Standing Facilities, which are used to manage overnight liquidity. Qualifying counterparties can use the Standing Facilities to increase the amount of cash they have available for overnight settlements using the Marginal Lending Facility. Conversely, excess funds can be deposited within the European Central Bank System (ECBS) and earn interest using the Deposit facility.
Counterparties must have collateral for the funds they receive from the Marginal Lending Facility and will be charged the overnight rate set by the ECBS. Excess capital can be deposited with the Deposit facility and they will earn interest at the rate offered by the ECBS. The rates for these two facilities signal the central bank system’s outlook for commercial interest rates and sets the upper and lower limit for interest rates on the overnight market.
