When rates are decent, money market funds are where brokerages park cash and often out-yield savings accounts. Knowing the fund/account distinction — and what insurance covers — is the difference between an informed choice and a surprise.

Know the two look-alikes
Money market DEPOSIT account: a bank product, FDIC/NCUA-insured within limits, rate set by the bank. Money market MUTUAL FUND: an investment bought through a brokerage, yield from short-term debt markets, not insured.
Know the fund families
Government funds hold Treasuries and government-backed paper (the most conservative flavor); prime funds add corporate short-term debt for slightly more yield; municipal funds trade yield for tax treatment.
Understand the $1 share convention
These funds aim to keep each share worth $1 and pay interest as dividends. Extremely rare stress events ('breaking the buck', 2008) are why regulation tightened — stability is the design goal, not a guarantee.
Match the tool to the job
Emergency fund you must never lose: insured accounts win. Cash at a brokerage waiting to be used, or a yield-chasing cushion beyond the insured fund: a government money market fund is the standard tool.

Những sai lầm thường gặp
- Assuming 'money market' means insured. Only the bank deposit version is.
- Parking next month's rent in any investment product. Timing risk is real even in conservative funds.
- Chasing a prime fund's extra 0.1% for an emergency fund. The safety margin is worth more than the sliver.
- Forgetting yields float. Last month's 4.5% is a snapshot, not a promise.
