Quick answer: While she was U.S. Treasury Secretary (2021 to January 2025), Janet Yellen repeatedly urged Congress to pass comprehensive legislation for digital assets, especially stablecoins, arguing that agency guidance alone could not provide durable oversight. She is no longer Treasury Secretary. Since she left office, Congress enacted the GENIUS Act stablecoin law in July 2025, while broader crypto market-structure legislation remained unfinished in the Senate as of mid-2026.

This post originally framed Yellen’s calls in the present tense. That needs a correction for accuracy. Janet Yellen served as the 78th Secretary of the Treasury from 2021 until January 2025, when her term ended with the change of administration. Her successor, Scott Bessent, was sworn in as the 79th Treasury Secretary on 28 January 2025. Yellen’s statements below reflect her position while she held the office, not a current role.
The core argument Yellen made
As Treasury Secretary, Yellen’s position was that regulatory agencies can issue guidance and bring enforcement cases, but they cannot create the kind of durable, comprehensive framework that only an act of Congress provides. Without statutory clarity, she argued, oversight of stablecoins, exchanges, and custody arrangements stays reactive rather than proactive. That view was widely shared across U.S. financial regulators, including at the Treasury and the Federal Reserve, which had flagged stablecoins as a potential financial-stability concern.
Stablecoins were the specific priority
Stablecoin legislation was the recurring focus, because stablecoins interact directly with the traditional banking system through the reserves that back them. The worry was concentration and contagion: if a large stablecoin failed and its reserves proved illiquid or insufficient, the fallout could spread into short-term funding markets. The proposed fix was clear reserve requirements, redemption rights, and issuer accountability standards written into law rather than left to guidance.
What actually changed after she left: the GENIUS Act
The legislative push she and others called for advanced under the next Congress and administration. On 18 July 2025, the GENIUS Act was signed into law, establishing a federal framework for payment stablecoins. According to the White House fact sheet, the law requires stablecoin issuers to hold 100% reserve backing in liquid assets such as U.S. dollars or short-term Treasuries, to publish monthly disclosures of reserve composition, and to follow anti-money-laundering and sanctions rules under the Bank Secrecy Act. It also prohibits misleading claims of government backing and, in an issuer insolvency, prioritizes stablecoin holders’ claims over other creditors.
Notably, several of those provisions map closely onto what Yellen-era Treasury officials had asked Congress to codify: reserve standards, issuer accountability, and consumer protection. The Treasury Department is among the agencies tasked with writing implementing rules for the new law.
The unfinished piece: crypto market structure
Stablecoins were only half of the legislative agenda. The other half, market-structure legislation defining when a digital asset is a security versus a commodity and dividing oversight between the Commodity Futures Trading Commission and the Securities and Exchange Commission, moved more slowly. The Digital Asset Market Clarity Act (the CLARITY Act) passed the U.S. House in July 2025 and was advanced by the Senate Banking Committee in May 2026, but as of mid-2026 it had not cleared the full Senate. The current Treasury Secretary has publicly urged Congress to finish that work. In other words, the broader clarity Yellen called for was still a work in progress well after she left office.
Why this matters
The useful takeaway is not any single official’s quote but the direction of travel: the United States has moved from agency guidance toward statutory rules for digital assets, starting with stablecoins. For businesses and individuals, that argues for structuring custody, reporting, and tax practices to hold up under codified standards rather than the loosest available interpretation, because the rules are being written now. For tax treatment specifically, the Internal Revenue Service maintains a digital assets resource page. None of this is investment advice, and the passage of a regulatory framework says nothing about the price or merit of any particular asset.
Common questions
Is Janet Yellen still the Treasury Secretary?
No. Janet Yellen served as the 78th U.S. Treasury Secretary from 2021 until January 2025. Her successor, Scott Bessent, was sworn in as the 79th Treasury Secretary on 28 January 2025. Yellen’s calls for crypto legislation were made while she held the office.
What did Yellen want Congress to do about crypto?
She urged Congress to pass comprehensive digital-asset legislation, with stablecoins as the priority, arguing that agency guidance and enforcement could not substitute for a durable statutory framework. Her concern was that gaps in oversight left consumers and financial stability exposed.
Did the United States pass a crypto law after Yellen left?
Yes, for stablecoins. The GENIUS Act was signed into law on 18 July 2025, creating a federal framework for payment stablecoins that requires full reserve backing, monthly reserve disclosures, and consumer protections. Broader market-structure legislation, the CLARITY Act, had passed the House but remained pending in the Senate as of mid-2026.
What does the GENIUS Act require of stablecoin issuers?
Per the White House fact sheet, it requires 100% reserve backing in liquid assets such as U.S. dollars or short-term Treasuries, monthly public disclosure of reserve composition, compliance with anti-money-laundering and sanctions rules, and priority for stablecoin holders’ claims in an issuer insolvency. It also bars misleading claims of government backing.
Does this article predict what crypto rules will look like next?
No. It describes the legislation enacted and pending as of mid-2026 from primary sources. The market-structure rules were still being negotiated, so the final framework could differ. This content is educational and does not forecast legislation or asset prices.
