The US Bureau of Labor Statistics is set to release the September Consumer Price Index (CPI) data despite the ongoing federal government shutdown. Although the exact release date is uncertain, it will not be on October 15th as initially scheduled. The bureau, which paused operations due to the funding lapse, missed its non-farm payroll report last week. However, it has started recalling employees to finalize the CPI report. This release is crucial for the annual Social Security cost-of-living adjustment, which relies on third-quarter inflation data. The delay in CPI data could impact the timing of this adjustment.
