Separately, if the government shuts down, the Bureau of Labor Statistics would completely cease operations, according to a Labor Department contingency plan, meaning they might not produce the monthly employment report, scheduled for Oct. 6, or the consumer price index, scheduled for Oct. 12.
If there is a government shutdown that lasts until the next Federal Reserve meeting, "then it's possible we wouldn't be getting some of the data that we would ordinarily get, and we would just have to deal with that," Federal Reserve Chairman Jerome Powell said at a Sept. 20 news conference, according to a transcript.
The next Federal Open Market Committee meeting is set for Oct. 31-Nov. 1.
The Labor Department's Employee Benefits Security Administration would furlough 743 of its 908 employees in the event of a shutdown, according to the Labor Department's contingency plan. EBSA oversees private retirement plans as well as other employee benefits.
While the Social Security Administration would furlough more than 13% of its employees in a shutdown, Social Security payments would not be affected. The SSA will only "cease activities not directly related to the accurate and timely payment of benefits or not critical to our direct-service operations," according to its contingency plan.
The longest government shutdown to date was also the most recent, spanning five weeks from December 2018 to January 2019 under the Trump administration.
