The U.S. Bureau of Labor Statistics will release the month-over-month Consumer Price Index (CPI) change for September 2026.
The Bureau of Labor Statistics (BLS) is the federal agency responsible for calculating and publishing monthly inflation data.
The May 2026 CPI report showed a 3.5% annual increase, establishing the baseline trend for inflation heading into the third quarter.
Determining whether September CPI exceeds -0.1% confirms if the U.S. experienced positive monthly inflation or a price decline for that month.
Note: The resolution threshold of -0.1% is a very low barrier for "positive" monthly inflation, meaning the market resolves to "Yes" unless September sees a distinct month-over-month price drop.
The Consumer Price Index for All Urban Consumers (CPI-U) increased 3.5 percent over the last 12 months to an index level of 333.952, according to the May 2026 report.

bls.govHistorical patterns indicate that monthly CPI declines below -0.1% are rare events typically associated with specific supply shocks or severe demand collapses, neither of which are currently documented as active trends.

While annual inflation is positive, the search results do not provide the specific month-over-month volatility data for June or July 2026 required to confirm the trajectory toward September.
bls.govThe absence of recent monthly data in the provided results creates uncertainty regarding whether temporary deflationary pressures could emerge in the third quarter before the September release.
