From the document: "The federal government experienced a funding gap beginning on October 1, 2025--the start of FY2026--and ending when the Continuing Appropriations, Agriculture, Legislative Branch, Military Construction and Veterans Affairs, and Extensions Act, 2026 (P.L. 119-37), was signed into law on November 12, 2025. Hereinafter, this report refers to the shutdown as the '2025 shutdown.' This funding gap resulted in a 'government shutdown' and the furlough of federal employees who were not excepted. P.L. 119-37 provided for all federal employees to be retroactively paid as if they had been at work for the shutdown period. This report discusses the effects of the 2025 shutdown on economic output. Gross domestic product (GDP) measures the value of goods and services produced in the economy. The shutdown could have potentially affected all components of GDP--government spending directly and private consumption, capital investment, and net exports indirectly. The effect of the shutdown on the economy depends on its scope and duration. The scope depends on two factors--the proportion of appropriated programs and agencies whose funding has lapsed and the extent that the President 'excepts' programs or agencies from the shutdown. Both factors will vary between historical shutdowns, making economic comparisons difficult. In the 2025 shutdown, funding lapsed for all appropriated programs and agencies--CRS [Congressional Research Service] could not locate any authoritative information on the total number of programs and agencies that were excepted--and the shutdown lasted for six weeks. The report also reviews third-party estimates of the effects of the shutdown on the economy. CRS does not plan to provide an independent estimate of the economic impact of the shutdown."
