US Federal Reserve Governor Michael Barr said Tuesday that clearer US stablecoin rules could accelerate the market’s growth, but cautioned that regulators must address money‑laundering risks, bank‑run risks and consumer protections as they implement the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act.
Speaking at a Federalist Society event on stablecoin regulation, Barr said the law provides “needed clarity” for issuers, but that “a great deal will depend on how federal and state regulators implement the statute.” He noted stablecoins remain used mainly for crypto trading and as a dollar store of value in some foreign markets, while also offering potential benefits such as lower remittance costs, faster trade‑finance processing and more efficient corporate treasury operations.
Barr highlighted several risks: bad actors buying stablecoins in secondary markets without identity checks, and issuers stretching for yield in reserve assets in ways that could undermine confidence during stress. His remarks come as agencies move from legislation to rule‑writing: the US Treasury opened a second round of public comment on implementing the GENIUS Act in September 2025, saying the law must be translated into rules that encourage innovation while addressing illicit finance, consumer protection and financial‑stability risks.
Barr signaled where implementation fights may land, flagging reserve‑asset rules, regulatory arbitrage, the scope of issuer activities beyond issuance, capital and liquidity requirements, anti‑money‑laundering checks and consumer protection standards as key open questions. The GENIUS Act, signed into law on July 18, 2025, created a federal framework for payment stablecoins in the United States and requires issuers to maintain one‑to‑one backing with reserve assets such as US dollars and Treasury bills. The law is expected to take effect 18 months after signing or 120 days after final agency rules are completed.
Other regulators are already preparing. Fed Vice Chair for Supervision Michelle Bowman told lawmakers in February that banking regulators were working on capital and liquidity rules for stablecoin issuers, and Federal Deposit Insurance Corporation Chair Travis Hill said in March that the agency does not expect stablecoins to receive deposit insurance under the law.
Barr framed the stablecoin debate in historical terms, warning that private money has a “long and painful history” when safeguards are weak. He pointed to the Free Banking Era, the Panic of 1907, money‑market fund stress during the global financial crisis and the COVID‑19 shock, and recent episodes of stablecoin valuation pressure as reasons to be cautious about assets marketed as redeemable at par on demand.
