Cons
- −1% foreign transaction fee on debit purchases (ATM withdrawals abroad are still rebated)

- −Brokerage statements and tax forms are overkill if you just want simple checking
Our Take
The Fidelity CMA is the power user's checking account: set SPAXX as your core position and every dollar waiting to pay rent earns money-market yield until the moment it leaves. Add unlimited ATM rebates and a $0 fee schedule and it outclasses traditional checking on almost every line. The 1% foreign debit purchase fee is the one travel wart, so carry a Schwab card or credit card abroad for purchases. For domestic one-account simplicity, this is the ceiling.
Best for: Optimizers who want every idle dollar earning money-market yield
