The Department of Homeland Security's partial shutdown, triggered by congressional impasse over immigration enforcement funding for ICE, CBP, and Border Patrol reforms, has lasted a record 76 days since February 2026, eclipsing the 2018-19 precedent. House Republicans advanced the bill via budget reconciliation to skirt filibuster obstacles, culminating in today's unanimous House passage of a Senate-backed appropriations measure funding most DHS agencies like TSA while deferring some border security allocations. The legislation now awaits President Trump's signature, expected imminently, potentially resolving the lapse absent veto or delays. Traders weigh this breakthrough against lingering partisan tensions and any executive actions, with no immediate congressional sessions until May.
