MMA - money market account
MMA, or money market account, is a high-yield checking/savings option provided by a bank. MMAs work like other checking accounts, except that they earn competitive yields, have minimum opening balances, and usually have restrictions on the number of withdrawals made within each period. If the bank is FDIC-insured, the MMA would be insured per the FDIC's coverage limitations.
