America’s Stablecoin Law Is Already Reshaping Who Buys Government Debt

It is the moment the federal apparatus fully engages with the GENIUS Act – legislation passed in July 2025 that established the first comprehensive federal oversight regime for digital assets in American history.

Alongside rules for so-called Permitted Payment Stablecoin Issuers, the agenda includes anti-money laundering and counter-terrorism financing standards, and a final rule prohibiting regulators from using “reputational risk” as grounds to deny banking services to crypto firms – a practice that had effectively locked much of the sector out of the traditional financial system for years. Additionally, the U.S. Department of Justice recently issued a notice, seeking public comments regarding the Genius Act.

How Stablecoin Issuers Became Treasury Buyers

According to the Genius Act, any stablecoin designed for payment purposes must be backed 1:1 with high-quality liquid assets – cash, short-term U.S. Treasuries, or equivalents. Issuers are required to redeem coins at par value on demand. Paying interest or yield to holders is explicitly prohibited.

In isolation, this sounds conservative. The downstream consequences are considerably larger. According to a report from the New York Times, more than 80% of the stablecoin market’s $250 billion-plus in reserves is already parked in U.S. Treasuries and repurchase agreements. Companies like Circle – issuer of USDC – have become among the largest private buyers of short-term government debt in the country. As the market grows – transaction volumes surpassed $4 trillion following the Act’s passage – that concentration deepens. Analysts are beginning to flag what they call “contraction risk”: a simultaneous mass redemption of stablecoins would force issuers to liquidate enormous volumes of Treasuries in a compressed timeframe, with unpredictable consequences for interest rates and broader credit markets. The threshold at which this concentration shifts from stabilizing to destabilizing has not yet been calculated by anyone with authority to act on the answer.

Federalism in the Digital Age

While coverage has focused largely on the federal dimensions of the legislation, a separate debate is quietly escalating in legal circles over the boundaries between federal and state authority. The GENIUS Act permits states to establish their own licensing regimes, provided they are “substantially similar” to federal requirements. The complication lies in the details. Section 16(d) allows state-chartered banks without federal deposit insurance – but with a stablecoin subsidiary – to conduct money transmission on a nationwide basis, a right that has historically required a federal license. State regulators have described this as an unprecedented override of state sovereignty.

Legal commentators are already questioning whether the Act’s preemption provisions conflict with constitutional limits on the federal government’s ability to commandeer state regulatory infrastructure – a question whose answer will come from courts, not from the agencies issuing rules this spring.

The Yield the Law Could Not Prohibit

The ban on interest payments is designed to prevent large-scale deposit flight from traditional banks toward stablecoin issuers. The reasoning is direct: if regulated coins offer yield, banks lose funding. The problem is that the law regulates issuers, not the exchanges that trade their products. Several crypto platforms are already offering indirect rewards or staking-adjacent mechanisms on regulated coins, effectively delivering returns to holders without the issuer technically paying them.

Whether this constitutes a legal loophole or legitimate market activity is a question regulators have not yet answered – and likely will not until the liquidity shift it may produce is already underway. The Bank Policy Institute has separately noted that the Act “retrofits special protections” onto assets whose fundamental legal nature remains poorly understood, particularly regarding whether a stablecoin payment legally extinguishes a debt in the same way a bank transfer does.

The Operational Risks Nobody Has Solved

Beyond the legal text, several technical questions carry direct consequences for systemic stability. The Act requires regulators to collaborate with the National Institute of Standards and Technology on cross-chain interoperability – how a regulated stablecoin moves safely between a private bank ledger and a public network like Ethereum, and who bears liability when that transfer fails, remains unresolved.

There is also the reserve composition problem. Former Federal Reserve Vice Chair Michael Barr raised concerns about repurchase agreements as reserve assets: in a bankruptcy, repo lenders have the right to seize collateral ahead of other creditors. If a stablecoin issuer holds repos as reserves and becomes insolvent, retail coin holders may find that the 1:1 backing guarantee is legally sound on paper and practically worthless in a crisis.

Consumer advocacy groups, including Consumer Reports, have argued the legislation leaves insufficient guardrails against large technology companies engaging in bank-like activity without full banking supervision. New York Attorney General Letitia James has criticized the absence of provisions requiring issuers to return stolen funds to fraud victims – a gap that sits awkwardly alongside the Act’s stated goal of consumer protection.

The End of Regulation by Lawsuit

The Act passed with an unusually broad bipartisan majority – 308 to 122 in the House and 68 to 30 in the Senate. Those numbers reflect a consensus that transcends ordinary political divisions: the era of managing digital asset markets through SEC enforcement actions and prosecutorial pressure has run its course. Core prohibitions take effect on January 18, 2027. All service providers have until July 18, 2028, to phase out non-compliant stablecoins. Federal regulators – the FDIC, OCC, and Federal Reserve – face a July 2026 deadline to finalize implementing rules.

The FDIC meeting on April 7 is not a procedural formality. It is the point at which the U.S. government formally acknowledges that digital dollars are a permanent feature of the financial system – and that the rules governing them need to reflect the scale they have already reached.
