On July 18, 2025, President Donald Trump signed the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, creating the primary federal guidelines for cost stablecoins. The regulation requires all stablecoin issuers to again tokens 100% with US {dollars} or short-term Treasury payments. It excludes corporate bonds and bank deposits.
This key provision converts stablecoins into engines for presidency debt purchases. Each time a stablecoin is issued, the corporate should concurrently buy Treasury securities of equal worth. As a end result, there’s an computerized, ongoing demand for federal debt exterior traditional bond auctions.

The European Central Bank reported in November 2025 that the worldwide stablecoin market surpassed $280 billion, led by Tether at $184 billion and USD Coin at $75 billion in market capitalization.
Treasury Secretary Scott Bessent underscored the Act’s strategic significance in his official assertion after its passage.

Between July and November, mandated Treasury purchases totaled $109 billion in simply 120 days. On common, stablecoin issuers purchased about $908 million in authorities debt every day—a quantity rivaling traditional institutions and central banks.
During remarks at the Treasury Market Conference on November 12, 2025, Secretary Bessent mentioned public sale sizes would stay regular because of stablecoin-driven demand. This demonstrates digital greenback adoption as a parallel funding supply for federal operations.
A Brookings Institution analysis in October 2025 supported these projections. The research suggests stablecoins may generate $2 trillion in additional demand for US authorities debt. This growth would essentially reshape world markets by changing crypto adoption into Treasury purchases.
Regulatory Shift: Fed to Treasury
The GENIUS Act transferred central oversight of stablecoin issuers to the OCC, a part of the Treasury Department. In July, OCC, the Office of the Comptroller of the Currency, announced it will supervise each financial institution and nonbank stablecoin issuers.
This shift removes stablecoin regulation from the Federal Reserve and consolidates it inside the Treasury’s government department company. The Treasury now holds vital affect over financial situations via digital asset coverage. This affect extends past rate of interest selections or market operations.
JPMorgan’s transfer to just accept Bitcoin as collateral after years of reluctance displays institutional recognition of this regulatory realignment. The nation’s largest financial institution sometimes solely shifts course in response to vital modifications in coverage and market construction.
Observers notice that each Treasury officers and personal actors, comparable to David Sacks, performed a job in shaping this course of. One analyst remarked that Bessent and Sacks demonstrated strategic imaginative and prescient via their regulatory strategy. They shifted management from the Fed to the Treasury whereas utilizing stablecoins to assist finance US debt.
