He described bank lobbying as an effort to slow blockchain adoption. Armstrong argued the push is not rooted in safety concerns.

Such measures would go beyond the Act’s explicit yield ban.Under the GENIUS Act, issuers cannot pay interest directly. However, platforms may offer rewards separately. Bank lobbying reportedly targets those mechanisms.Community bank advocates warn of deposit outflows. Industry responses reference research showing limited impact on local lending. The disagreement reflects competitive pressure rather than systemic risk.The GENIUS Act was signed into law on July 18, 2025. It created the first federal stablecoin framework that defines payment by stablecoins and sets strict oversight standards.Issuers must maintain one-to-one reserves with liquid assets and publish monthly disclosures.
