The bill on stablecoins in the United States, notably the GENIUS Act, is causing tensions in the Senate. Supported by Republicans, it aims to establish a regulatory framework for stablecoins, requiring a 1:1 backing with dollars or liquid assets, and oversight by the Federal Reserve for large issuers. However, nine pro-crypto Democrats, some of whom initially supported the bill, have withdrawn, citing national security and anti-money laundering concerns. This turnaround jeopardizes the imminent vote, scheduled before May 26, and threatens the adoption of this historic legislation.
