Federal Reserve Governor Michael Barr said clearer U.S. stablecoin rules could speed market growth, but warned regulators must guard against money‑laundering, bank‑run and consumer‑protection risks as they implement the GENIUS Act.
Speaking at a Federalist Society event, Barr called the law “needed clarity” for issuers while emphasizing that much will turn on how federal and state agencies write and enforce implementing rules. He noted that today stablecoins are used predominantly for crypto trading and as a dollar‑store of value in some overseas markets, yet they also have potential benefits—lower remittance costs, faster trade‑finance processing and more efficient corporate treasury operations.
Barr outlined specific vulnerabilities: bad actors can buy stablecoins in secondary markets without identity checks, and some issuers may chase higher yields in reserve assets in ways that could undermine confidence during stress. Those concerns come as regulators move from statute to rule‑writing. The U.S. Treasury opened a second round of public comments in September 2025 on GENIUS Act implementation, saying the law must be translated into rules that both foster innovation and address illicit finance, consumer protection and financial‑stability risks.
The governor flagged several implementation battlegrounds: what qualifies as permissible reserve assets, how to prevent regulatory arbitrage between federal and state regimes, whether and how to limit issuer activities beyond minting stablecoins, the appropriate capital and liquidity standards, required anti‑money‑laundering checks, and baseline consumer‑protection obligations. The GENIUS Act, signed into law on July 18, 2025, establishes a federal framework for payment stablecoins, requires one‑to‑one backing with reserves such as U.S. dollars and Treasury bills, and is slated to take effect 18 months after signing or 120 days after final agency rules are completed—whichever comes later.
Other regulators are preparing for rulemaking. Fed Vice Chair for Supervision Michelle Bowman told lawmakers in February that banking regulators are working on capital and liquidity rules for stablecoin issuers, and Federal Deposit Insurance Corporation Chair Travis Hill said in March that the FDIC does not expect stablecoins to qualify for deposit insurance under the law.
Barr placed the current debate in historical context, warning that private money has a “long and painful history” when safeguards are weak. He cited episodes from the U.S. Free Banking Era and the Panic of 1907 through money‑market fund strains in the global financial crisis and the COVID‑19 shock, as well as recent episodes of stablecoin valuation pressure, as reasons to be cautious about assets marketed as redeemable at par on demand.
