As of May 2026, the United States is no longer merely talking about stablecoin regulation; it is constructing a full supervisory architecture around it. The GENIUS Act became law on July 18, 2025, and in early 2026 the OCC, FDIC, and Treasury moved from broad statutory language to detailed rulemaking. Treasury’s April 8, 2026 proposal would treat permitted payment stablecoin issuers as financial institutions under the Bank Secrecy Act and require anti-money-laundering and sanctions-compliance programs, while the banking agencies are drafting parallel rules on reserve assets, redemption, custody, capital, and supervision. Under the OCC’s timeline, the law takes effect on January 18, 2027, or earlier if the key regulators finalize their rules 120 days sooner. (congress.gov)
What will this do to bank deposits? Probably less a sudden disappearance than a rearrangement of the banking system’s funding structure. Federal Reserve researchers argue that the effect depends on who buys stablecoins, which assets they sell to do so, and how issuers hold reserves. If reserves remain largely in bank deposits, aggregate deposits may stay inside the system but become more concentrated and more wholesale in character; if reserves migrate into Treasury bills, repos, or money funds, banks could lose stable funding and, over time, lend less. The law also prohibits issuers from directly paying interest, which weakens stablecoins as a simple substitute for savings accounts. Just as important, the FDIC has stressed that payment stablecoins are not insured deposits, whereas tokenized deposits that meet the legal definition of a deposit remain deposits. That distinction gives banks a strong incentive to compete with their own tokenized products rather than surrender customers to nonbank issuers. (federalreserve.gov)
The global consequence may be even larger. The IMF estimated in December 2025 that 97 percent of stablecoin issuance was dollar-denominated, and it argues that wider use of dollar stablecoins could strengthen demand for US Treasuries and reinforce the dollar’s international role, especially in faster and cheaper cross-border payments. Yet this is not the same as permanently freezing dollar supremacy. The IMF also notes that the dollar remains the world’s preeminent reserve currency even as its official reserve share has drifted down gradually over time. In other words, US regulation may not restore an older form of dollar hegemony; it may create a new one, in which the dollar circulates ever more widely through privately issued, tightly regulated digital tokens.
