The U.S. federal government shutdown began at 12:01 a.m. EDT on October 1, 2025, due to Congress failing to pass appropriation legislation for the 2026 fiscal year. The shutdown resulted from partisan disagreements over federal spending levels, health insurance subsidies, and foreign aid rescissions. As of now, it is unclear how long the shutdown will last. Historically, government shutdowns vary in length; the last major shutdown in 2018-2019 lasted 35 days. This shutdown was triggered by an impasse between President Donald Trump's Republican-led government and the Democratic opposition, with no agreement reached on a temporary funding extension that included healthcare subsidies demanded by Democrats. Negotiations remain stalled, and the shutdown will continue until Congress passes a funding bill to reopen the government. The House passed a continuing resolution extending funding till November 21, 2025, but it faces a filibuster in the Senate with no bipartisan consensus yet. Therefore, the government shutdown duration is currently indefinite and depends entirely on when Congress and the President can agree on the funding legislation to end the impasse.
