In brief

• The SEC abruptly canceled a Friday open meeting that would have launched formal rulemaking on Regulation Crypto Assets, a new framework for crypto fundraising, just three days after announcing it.
• Sources say Wall Street trade group SIFMA, which has lobbied against broad regulatory exemptions for crypto and tokenized-securities firms, raised the prospect of legal action over the SEC’s statutory authority, contributing to the agency standing down.
• The policy conversation continues this week with a White House event Wednesday featuring Trump and top crypto executives, the CFTC’s inaugural Innovation Advisory Committee meeting Thursday, and ongoing Clarity Act negotiations ahead of a September 15 cloture vote.
