The federal shutdown’s impact on the US economy is likely to be minimal, despite President Trump’s threat to eliminate thousands of jobs. While some financial markets may experience fluctuations, funding restoration should restore order soon. However, if workers are permanently laid off, it could worsen an already precarious economy.
In a typical shutdown, financial markets adjust quickly once funding is restored, and workers receive back pay. The Congressional Budget Office estimates that even the longest shutdown on record had only a 0.02% decrease in US GDP.
