Where to Park Cash in a Brokerage Account
Compare current yields across brokerage cash funds, cash ETFs, Treasuries, and savings alternatives.
Overview
The right place for brokerage cash depends on when it will be invested, how quickly it must be available, tax treatment, and whether principal stability or deposit insurance is required.
This comparison uses only YieldFinder's existing money-market, Treasury, and savings datasets. It does not estimate brokerage sweep rates or add manually maintained products.

Frequently Asked Questions
Where can I park uninvested cash in a brokerage account?
Common choices include a brokerage sweep, a money market mutual fund, a cash-oriented ETF, or short-term Treasury securities. Availability depends on the brokerage.
Can APY, SEC yield, and Treasury yield be compared directly?
Not perfectly. They are different yield measures. This page labels each metric so users can compare current levels without implying that their calculation methods, taxes, liquidity, or risks are identical.
Does YieldFinder track brokerage sweep rates on this page?
No. The current page only displays product categories supported by YieldFinder's existing rate tables. Brokerage sweep rates are not estimated or entered manually.
