Money Market Deposit Account (MMDA) is a deposit-account concept used to manage cash access, payments, balances, or bank liquidity.
A Money Market Deposit Account (MMDA) is a type of deposit account commonly offered by banks and credit unions that typically provides a higher interest rate compared to standard savings accounts. These accounts combine features of both savings and checking accounts, offering limited check-writing capabilities while ensuring your funds can accrue more interest.
One of the main attractions of MMDAs is the potential for higher interest earnings. These accounts often offer tiered interest rates, meaning higher balances can secure higher interest rates.
Unlike certificates of deposit (CDs), MMDAs offer more flexibility due to limited check-writing and ATM access, although transactions are typically capped at six per month by Regulation D federal guidelines.
The introduction of MMDAs dates back to the early 1980s, a period marked by deregulation in the banking sector. They were created to provide a competitive edge for banks and savings institutions against mutual funds and other higher-yielding investment options.
MMDAs are well-suited for individuals looking to earn a better return on their savings while maintaining some access to their funds.
Small businesses may also find MMDAs attractive for maintaining liquidity while earning interest on funds that are not immediately needed for operating expenses.
