Cash Sweep Programs: Brokerage Cash Checklist
Uninvested cash is not a footnote. A broker may leave it as a free credit balance, sweep it into a bank deposit program, or sweep it into a money market fund. The choice can change yield, liquidity, disclosures, and whether bank or brokerage protection applies.

Three places idle cash can sit
Free credit balance
FINRA describes uninvested cash left in a brokerage account as a free credit balance. Firms may or may not pay interest on it.
Bank sweep program
Investor.gov explains that bank sweep programs move unused brokerage cash into bank accounts, where FDIC insurance may apply within limits.
Money market fund sweep
SIPC explains that money market mutual funds are treated as securities for SIPC protection purposes, not as bank deposits.
Questions to ask before leaving cash idle
Identify the exact cash destination
Ask whether idle cash remains at the broker, moves to one or more bank deposit accounts, or goes into a money market mutual fund. Investor.gov notes that each cash sweep program has different features.

FINRA notes that firms may or may not pay interest on a free credit balance, and that sweep programs typically pay interest on swept cash. The relevant rate is the one that applies to your actual account type and balance.

Investor.gov explains that cash in a bank sweep program is held outside the brokerage firm and would not be protected by SIPC if the brokerage firm fails. SIPC separately explains how it treats cash and money market funds in brokerage accounts.

Cash sweep FAQ
Is swept brokerage cash always FDIC insured?
No. FDIC insurance depends on whether cash is swept into deposit accounts at participating FDIC-insured banks and whether the balance is within applicable limits. Money market funds are not bank deposits.
Is a cash sweep the same as leaving cash at the broker?
No. FINRA describes uninvested brokerage cash as a free credit balance, while a sweep program may move cash into a bank deposit account or money market fund. The protection and yield can differ.
Should I chase the highest sweep yield?
Yield matters, but it is not the only question. Liquidity, fees, program banks, FDIC limits, SIPC treatment, debit-card or bill-pay features, and account type all matter before choosing where idle cash sits.
