[U.S. Crypto Market Structure Bill Negotiations Stalled, DeFi Regulation and Stablecoin Yields in Focus] U.S. Senate Banking Committee Chairman Tim Scott had announced a hearing on the Crypto Market Structure Bill review for January 15, but negotiation documents reveal that consensus has yet to be reached on four key issues. The main disagreements include: requiring DeFi to undergo the same level of oversight as federally regulated financial institutions, though its definition and related issues remain unresolved; the GENIUS Act stipulates that stablecoin issuers cannot offer interest, but affiliated companies may provide yields, raising concerns within the banking industry; prohibiting senior U.S. government officials from deriving personal benefits from crypto activities; and the CFTC taking a leading role in cryptocurrency regulation, though bipartisan seat allocation needs to be balanced.
