The Congressional Budget Office estimated the effects of the five-week partial shutdown of the government that began in December 2018 and ran through January 25, 2019. Their findings showed that the partial shutdown delayed approximately $18 billion in federal discretionary spending for compensation and purchases of goods and services and suspended some federal services.

As a result of economic activity, CBO estimated that real gross domestic product (GDP) in the fourth quarter of 2018 was reduced by $3 billion in relation to what it would have been otherwise. In the first quarter 2019, the level of real GDP was estimated to be $8 billion lower than it would have been—an effect reflecting both the five-week partial shutdown and the resumption in economic activity once funding resumed.
