The US Department of the Treasury has initiated a second public comment period on the implementation of the GENIUS Act, a law aimed at regulating stablecoin payments in the United States. This follows the initial comment period that began in August, with the current window open until October 17. The Treasury is seeking feedback on the advance notice of proposed rulemaking, despite it not being a requirement for the GENIUS Act's implementation. The Act, signed into law by President Donald Trump in July, is part of a broader legislative effort to regulate cryptocurrency, with implementation expected by late 2026. In related developments, the US Senate is preparing to vote on a digital asset market structure framework, potentially titled the Responsible Financial Innovation Act. This bill aims to define the roles of US financial agencies in crypto regulation. The Senate Banking Committee, led by Senator Cynthia Lummis, plans to vote on the bill by the end of September, with the possibility of it becoming law by 2026. Lawmakers have engaged with crypto industry executives in recent discussions to refine the market structure and Bitcoin reserve bills.
