When investors sell securities or deposit money into a brokerage account, the cash may remain uninvested for a period of time. Some brokerage firms automatically move eligible idle cash into a cash sweep program.
The arrangement can be convenient, but investors should understand where the money is held, how it earns interest, and what protections apply.
What is a cash sweep?
A cash sweep program generally moves eligible uninvested brokerage cash into one or more designated accounts or investment vehicles. Depending on the brokerage program, this may involve deposits at participating banks or an investment in a money market mutual fund.
These arrangements are not all the same. The account's terms determine how the cash is handled and what protections may apply.
Bank deposit sweeps
Some brokerage firms place cash into deposit accounts at participating banks. Eligible deposits may receive FDIC insurance, subject to the standard insurance limits and ownership-category rules.
The fact that cash is held through a brokerage does not automatically make every cash balance FDIC-insured. Investors should review which banks participate, how deposits are allocated, and whether they already hold deposits at those institutions.
Money market fund sweeps
Other programs use money market mutual funds. These are securities, not bank deposits, and are not insured by the FDIC.
Money market mutual funds generally aim to maintain stable share values, but they are investments and carry risks. They should not be confused with money market deposit accounts offered by banks.
Compare the interest rate and terms
Cash sweep rates can vary among brokerage firms and may change over time. Investors should compare the rate, withdrawal arrangements, program fees, and any conditions that affect the amount earned.
A high-yield savings account or another cash-management product may be worth comparing, depending on the investor's needs and the protections offered.
Bottom line: Uninvested brokerage cash does not always sit in the same type of account. Check whether a sweep program uses bank deposits or money market funds, and understand the relevant insurance and investment risks.
