About CashRate Watch

CashRate Watch answers one question: where should cash sit this week?

Every week we check the published rates for high-yield savings accounts, money market funds, broker cash programs, US Treasury bill auctions and USDC rewards. We put them in one table with a plain risk label, so you can see the trade-off between yield and safety at a glance.

How we collect rates

• Each rate is read from the provider's public website or official data, for example the US Treasury's FiscalData API for T-bills. Every row links to its source.
• If we can't read a rate directly, we leave it out. We never estimate or fill in a number.
• Promotional rates, balance tiers and subscription requirements are noted under each name.
