Gregory Daco, chief economist at accounting giant EY, said this shutdown will leave a lasting mark on the U.S. economy. The longest federal government shutdown in U.S. history appears to be nearing an end, but not without leaving a mark on an already struggling economy.About 1.25 million federal workers haven’t been paid since October 1. Thousands of flights have been canceled, a trend that is expected to continue this week even as Congress moves toward reopening the government. Government contract awards have slowed and some food aid recipients have seen their benefits interrupted.Most of the lost economic activity will be recovered when the government reopens, as federal workers will receive back pay. But some canceled flights won’t be retaken, missed restaurant meals won’t be made up, and some postponed purchases will end up not happening at all.“Short-lived shutdowns are usually invisible in the data, but this one will leave a lasting mark,” Gregory Daco, chief economist at accounting giant EY said, “both because of its record length and the growing disruptions to welfare programs and travel.”The Congressional Budget Office (CBO) estimated that a six-week shutdown will reduce growth in this year’s fourth quarter by about 1.5 percentage points. That would cut growth by half from the third quarter. The reopening should boost first-quarter growth next year by 2.2 percentage points, the CBO projected, but about $11 billion in economic activity will be permanently lost.The previous longest government shutdown, in 2018-2019, lasted 35 days but only partially shut the government because many agencies had been fully funded. It only nicked the economy by about 0.02% of GDP, the CBO said then.The current shutdown is adding to the economy’s existing challenges, which include sluggish hiring, stubbornly elevated inflation, and President Donald Trump’s tariffs, which have caused uncertainty for many businesses. Still, few economists foresee a recession.About 650,000 federal workers didn’t work during the shutdown, which will likely boost the unemployment rate by about 0.4 percentage points in October, or to 4.7% from 4.3% in August, when the last report was released. Those workers would all then be counted as employed once the government reopens.Here are the ways the government closure is weighing on the economy:
