Story details
Rosstat’s 7 October estimate puts the consumer price index for 29 September to 5 October 2026 at 100.96% relative to the previous registration date. In the release’s cumulative measures, the index stood at 100.90% since the start of October and 105.94% since the start of 2026.
The 100.96% reading is a one-week comparison, while the October and year-to-date values use their respective starting points. They are index levels expressed relative to a base of 100, rather than percentage changes written as index levels; the week’s estimated increase corresponds to 0.96%.
The release is a weekly estimate and sits alongside Rosstat’s separate monthly CPI publication for September. It should not be combined with that monthly result as though the periods or reference dates were identical. The statement reports a national index, not a price for a single product or region.
This is a measurement of the period ending 5 October, published two days later. It describes prices observed in the survey period and does not forecast subsequent inflation. Rosstat’s original release provides the precise reference dates for the previous registration, start of month and start of year.
