Park your money temporarily
Keep your cash in a money market fund for short-term needs or until you decide how to invest it.
Get easy access to your cash
Transfer money between your bank and your Vanguard accounts whenever you need to.
Settle brokerage trades
Your settlement fund is used to pay for and receive proceeds from brokerage transactions, including Vanguard ETFs®, in your Vanguard Brokerage Account.
