Treasury Proposes Due Diligence Rules for Stablecoin Issuers

The U.S. Treasury has proposed mandatory due diligence requirements for payment stablecoin issuers, folding third-party counterparties into a federal and state licensing framework tied to the GENIUS Act. The plan, released as part of the Act's implementation, would force issuers to examine the firms they deal with and follow existing banking due diligence rules.

The scope is precise. The requirements apply to permitted payment stablecoin issuers — the licensed category created under the GENIUS Act — and treat third-party counterparties as licensed entities within a dual federal and state licensing structure. Treasury describes the proposed checks as similar to the scrutiny U.S. regulators apply to correspondent banks, a comparison that signals just how far the digital-asset sector is being pulled toward traditional banking standards.

What does this change for issuers?

In practice, it converts counterparty review from good hygiene into a compliance obligation. Issuers would have to examine their counterparties and apply banking-grade due diligence procedures, with the checks made mandatory rather than discretionary.

The stated goals are accountability, security and financial stability in stablecoin operations. The proposal also reflects a broader tightening of scrutiny over financial institutions involved in digital assets, particularly around sanctions and security concerns — a regulatory pressure point that has grown alongside the sector's balance sheets.

Issuers will likely need to reassess existing operations to adapt. Counterparty relationships that passed informal review may not survive a correspondent-bank-style examination, and firms without established compliance infrastructure face the heaviest lift.

When would the rules bite?

The effective date remains open. Treasury has tied the compliance timeline to finalization of the proposal, meaning the clock starts only once the rulemaking process concludes. That leaves issuers an indeterminate window to prepare — but no basis to assume delay.

For a sector that has operated largely outside bank-style counterparty controls, the direction of travel is now unambiguous. Stablecoin issuers seeking permitted status under the GENIUS Act will find their licenses conditioned on banking-grade diligence, and counterparties without the credentials to match may find themselves cut out of permitted payment chains as the framework takes effect.
