A Money Market Account (MMA) is a type of deposit account offered by banks and credit unions that provides a balance between accessibility and higher interest earnings. Unlike traditional savings accounts, MMAs usually offer better interest rates, often variable and tiered based on balance levels, while allowing limited transactions such as check-writing, debit card use, and ATM withdrawals.
Origins of Money Market Accounts
Money market accounts were created in response to financial market changes in the late 1970s and early 1980s. Before MMAs existed, Regulation Q capped the interest rates banks could pay on deposits, limiting savers’ earnings. To circumvent this, investors turned to money market mutual funds—investment vehicles that pooled money to buy low-risk, short-term securities. These funds offered higher returns but lacked federal insurance.
In 1982, the Depository Institutions Deregulation and Monetary Control Act allowed banks and credit unions to offer Money Market Deposit Accounts (MMDAs), which we now call Money Market Accounts. These accounts offered market-competitive rates while maintaining federal insurance through the FDIC or NCUA, making them a safer alternative to money market mutual funds.
Key Features of Money Market Accounts
- Higher Interest Rates: MMAs typically offer higher, variable interest rates that may increase with larger account balances.
- Limited Transactions: Most MMAs have limits on the number of certain transactions per month, often around six, including checks, debit card purchases, and transfers. While Regulation D’s six-transaction limit was removed in 2020, many institutions still impose limits to manage liquidity.
- Minimum Balance Requirements: MMAs often require a higher minimum deposit or balance. Falling below this minimum can trigger fees or reduced interest rates.
- Federal Insurance: Funds in MMAs are insured up to $250,000 per depositor, per insured bank or credit union, by the FDIC or NCUA, providing safety and peace of mind.
When to Consider a Money Market Account
- Emergency Fund: They offer a safe, accessible place to store your emergency savings while earning more than a typical savings account.
- Short to Mid-Term Savings: Perfect for funds you want to grow over months or years but still need to access flexibly, like a down payment or business cash reserves.
- Temporary Holding Place: Use an MMA to hold proceeds from investments or bonuses temporarily before reinvesting.
Who Benefits From an MMA?
MMAs suit savers who need both liquidity and higher yields, including individuals with significant savings, risk-averse savers, small business owners managing cash reserves, and anyone building an emergency fund.
Important Distinctions: MMA vs. Money Market Fund
Confusing MMAs with money market mutual funds is common but critical to avoid:
- Money Market Account (MMA): A bank deposit product, federally insured, with variable interest and limited transaction access.
- Money Market Fund (MMF): A mutual fund investing in short-term securities, not federally insured, and subject to market risk.
