Mercury Mercury Tea Room
A plan byMercury
Mercury is a business account offering FDIC coverage up to $5M via sweep, free domestic wires, the IO Card with 1.5% cashback, a Treasury yielding up to ~3.6% net (official figure as of 05/31/2026, for large balances) and free APIs.

Verdict
Mercury tops the category thanks to FDIC coverage up to $5M via sweep, the only genuine deposit guarantee in the group, alongside free domestic wires, a Treasury yielding up to ~3.6% net and solid APIs. The top rating comes with three caveats, though: US-only availability and partner bank Choice Financial hit by a federal consent order in 2023.
Exactly what makes it so strong on protection makes it weak here: full KYC, a fully custodial account, no native crypto support and a single country of operation. Its rootedness in the US FDIC system is the opposite of censorship resistance and self-custody.
