Definition: Overnight deposit
Deposit that is convertible into currency and/or is transferable on demand by cheque, banker’s order, debit entry or similar means, without significant delay, restriction or penalty. Balances representing prepaid amounts in the context of e-money, either in the form of hardware-based e-money (e.g. prepaid cards) or software-based e-money issued by MFIs (Monetary financial institutions), are included. Non-transferable deposits, which are technically withdrawable on demand but which are subject to significant penalties, are excluded.
