FinCEN's February 2026 CDD relief — does it help me open additional accounts?

FinCEN's February 2026 exceptive relief allows a covered US financial institution to choose NOT to re-collect beneficial ownership information at each additional new account opening for an EXISTING legal entity customer at that same institution. So if you have a Mercury checking account and open a Mercury savings account or a Mercury treasury account, Mercury MAY (at its discretion) skip re-collecting your BOI because they already have it on file. The relief is discretionary, not mandatory — Mercury can still re-collect if its risk-based procedures call for it.

The relief does NOT cover opening your FIRST account at a NEW institution. In your scenario, opening a Relay account when you currently bank with Mercury is a first-account opening at Relay — they have no existing customer relationship with you. Relay must do full CDD as if you've never been onboarded anywhere. The relief also does not reduce the rigor of: (1) initial KYC at any new provider; (2) ongoing monitoring obligations; (3) risk-based refresh of BOI when something looks inconsistent; (4) the bank's own elective CDD policies that go beyond the regulatory floor.

If you bank at Mercury and want to add a Mercury treasury or savings product, the relief MAY reduce friction (depends on Mercury's risk assessment of your account). If you want to add Relay for redundancy/diversification, treat it as a full first-onboarding — gather formation documents, EIN letter, passport, real operating address proof, source-of-funds, and beneficial owner data fresh. Don't expect Relay to call Mercury for your file. Don't expect onboarding speed advantages from your Mercury history.

Post-Synapse/Evolve, sponsor banks remain under supervisory pressure to be rigorous at first onboarding. The Feb 2026 relief is a narrow easing for already-onboarded customers, not a signal that first-account access is loosening. If you're a foreign-owned LLC adding banks for diversification, plan time and documentation for each first onboarding separately. The relief helps maintenance, not new acquisition.
