According to the source, the U.S. Securities and Exchange Commission states in its Operations Plan Under a Lapse in Appropriations that during a government shutdown it will suspend most normal operations, including the review and approval of registrations, applications, and exchange rule filings (SEC.gov). The SEC plan further notes that while systems like EDGAR can continue to accept submissions, staff reviews and actions on pending matters are largely paused, implying decisions on crypto-related exchange-traded products will not be issued until funding is restored (SEC.gov). Historically, shutdowns delay federal agency actions on pending approvals, reinforcing the expectation of slippage in altcoin ETF timelines during a lapse in appropriations (Congressional Research Service, crsreports.congress.gov).
