Monthly consumer price inflation (OECD)
The change in the national consumer price index for all items compared with the same month a year earlier, as compiled by the OECD from national sources. National CPIs follow national methods, so they can differ from the harmonised EU index. Countries that have moved to the 2018 classification of consumption (COICOP 2018) are taken from the OECD's COICOP 2018 table, the others from its earlier table; each country's series comes from one table only.
46 countries have a value for September 2026, the latest period with data for most countries. Some countries have newer figures; see the ranking below for each country's latest year.
