FinCEN Proposes Stablecoin KYC Rules, Ending Regulatory Honeymoon

The Financial Crimes Enforcement Network (FinCEN) has proposed rules for stablecoin issuers to implement customer identification programs, marking a significant shift in regulatory compliance. The proposal is part of the GENIUS Act, which established a comprehensive framework for digital payment currencies in the United States.

Under current rules, nonbank stablecoin operators are only required to verify customer identities on higher-value transactions. However, the proposed rule would extend Bank Secrecy Act customer identification obligations to permitted payment stablecoin issuers (PPSIs), requiring them to establish a written customer identification program before opening accounts.

The proposal also introduces stablecoin-specific definitions of 'account' and 'customer' that depart from traditional banking rules. Issuers must collect customer name, physical address, date of birth or date of formation, taxpayer identification number, risk-based documentary or non-documentary identity verification procedures, watch-list screening against government databases, and customer notification at account opening.

The proposed rule applies only to direct primary-market relationships between issuers and customers. Secondary-market transactions, where users interact through smart contracts without direct issuer contact, are excluded. However, the agencies have left open questions regarding redemption flows from secondary-market buyers, which could reshape business models for some issuers.
