Government Shutdown Cut Into Economic Growth, CBO Says

A sign at the entrance of the Smithsonian National Museum of Natural History in Washington, D.C., says the museum will reopen Tuesday. The shutdown reduced federal spending by $18 billion, although most of that will be recouped, now that the government has reopened, according to a new report.

The partial shutdown of the government reduced federal spending by about $3 billion and cut into overall U.S. economic growth, according to a report released Monday by the nonpartisan Congressional Budget Office.

The report says that because of the shutdown, which lasted from Dec. 22 through last Friday, about $18 billion in discretionary government spending was delayed. Most of the money will be spent later, now that the shutdown has ended.
