This bill, titled the "Digital Asset Market Structure and Investor Protection Act," aims to establish a comprehensive regulatory framework for digital assets in the United States. It distinguishes between "digital asset securities," regulated by the SEC, and "digital assets" (including Bitcoin and Ether), regulated as commodities by the CFTC. The bill introduces a "desecuritization" process for mature digital asset securities and mandates joint SEC/CFTC rulemaking for asset classification. It proposes Treasury Department approval for fiat-backed stablecoins, authorizes the Federal Reserve to issue digital Federal Reserve notes, and clarifies that digital assets are not federally insured deposits. Furthermore, it expands Bank Secrecy Act definitions and directs FinCEN to issue rules against anonymizing services and anonymity-enhanced virtual currencies.
