The longest-ever US government shutdown disrupted official employment and inflation data, further clouding policymakers' perceptions.

True: the US federal government shutdown that began on 1 October 2025 became the longest in US history (longer than the 35-day shutdown of 2018–19), and it delayed, suspended or cancelled official employment and inflation releases (for example BLS jobs reports and CPI), with Fed officials or credible reporting describing the resulting gap in data as making policy harder. Mostly true: all of this holds except a minor detail, for example only one of the two data types was disrupted and the other was merely delayed briefly. Mixed: the shutdown was the longest ever but data disruption was limited, or the data were disrupted but the shutdown was not the longest ever. Mostly false: the shutdown was not the longest ever and official data releases continued with only minor delays. False: no shutdown disrupted employment or inflation data in that period.

   “Federal government agencies were shut down or operating at reduced staffing levels during a lapse in appropriations from October 1, 2025, through November 12, 2025. Most CPI operations, including data collection, were suspended during that time period.”

   “BLS did not issue an October 2025 CPI news release.”

   “The most recent—and longest—government-wide funding gap and shutdown to date started in FY2026 on October 1, 2025, and lasted for a total of 42 full days.”

   “Additionally, the BLS was unable to collect data used to calculate the unemployment rate and labor force participation rate in October, saying that "household survey data from the Current Population Survey were not collected for the October 2025 reference period due to a lapse in appropriations and will not be collected retroactively."”

The Congressional Research Service calls the shutdown that began on October 1, 2025 the longest government-wide funding gap to date, at 42 full days (E3). The BLS says most CPI operations, including data collection, were suspended from October 1 to November 12, 2025, and that no October 2025 CPI release was issued (E1, E2). A Richmond Fed analysis reports that the October household survey data behind the unemployment rate were not collected and will not be collected retroactively (E4). Both the longest-ever shutdown and the disruption to jobs and inflation data are confirmed. However, the quoted evidence does not directly show Fed officials saying the data gap made policy harder, so that part rests only on the Richmond Fed analysis of the missing data.
