US Federal Reserve Governor Michael Barr said Tuesday that clearer US stablecoin rules could speed the market’s growth, but warned that regulators still need to address money laundering risks, bank run risks and consumer safeguards 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.”
Barr said stablecoins are still used mainly for crypto trading and as a US dollar store of value in some foreign markets, though they could also lower remittance costs, speed up trade finance processing and help firms manage treasury operations. He also highlighted the risk of bad actors buying stablecoins in secondary markets without identity checks, and said issuers may be tempted to stretch for yield in reserve assets in ways that undermine confidence during stress.
Barr’s remarks come as US agencies move from legislation to rule-writing. The US Treasury Department opened a second round of public comment on implementing the GENIUS Act in September 2025, saying the law must be translated into rules that both encourage innovation and address illicit finance, consumer protections and financial stability risks.
Fed Vice Chair for Supervision Michelle Bowman told lawmakers in February that banking regulators were already 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’s speech signals where the implementation fights may land. He flagged reserve asset rules, regulatory arbitrage, the scope of issuer activities beyond issuance, capital and liquidity requirements, Anti-Money Laundering (AML) checks and consumer protection standards as the key issues still to be settled.
The GENIUS Act, signed into law on July 18, 2025, created a federal framework for payment stablecoins in the United States. The law requires issuers to maintain one-to-one backing with reserve assets such as US dollars and Treasury bills, and is expected to take effect 18 months after signing or 120 days after final agency rules are completed.
Barr’s speech also cast the stablecoin debate in historical terms. He said private money has a “long and painful history” when safeguards are weak, pointing to the Free Banking Era in the US, the Panic of 1907, money market fund stress during the global financial crisis and COVID-19 shock, and more recent stablecoin valuation pressure as reasons to be cautious about any asset marketed as redeemable at par on demand.
