Opening a bank or fintech account in Miami

A plain-English rundown of how banking and payments work in Miami, United States — the regulator to verify, the currency you'll transact in, how local accounts are addressed, and the rails that move your money. Treat these as the checks to make before you commit, not marketing.

The essentials

Four things worth confirming before you open or fund an account in Miami.

Regulator

Office of the Comptroller of the Currency (OCC)

Most US fintech accounts are actually held at a partner bank insured by the FDIC, with consumer-protection oversight from the Office of the Comptroller of the Currency (OCC). Before opening an account in Miami, find out which chartered bank holds your deposits and confirm its FDIC status.
