Inflation Rate MoM

The Inflation Rate MoM is the one-month % change in the Harmonised Index of Consumer Prices for the European Union. Eurostat, the statistical office of the European Union, compiles it as the European Index of Consumer Prices, the whole-EU aggregate. The basic index is compiled and published on a monthly basis. It tracks household cash spending on the economic territory, meaning money actually paid for goods and services meeting direct needs.

It covers all households regardless of nationality or residence status. The common framework takes precedence over national definitions for comparability. It excludes noncash owner housing imputations, narcotics, noncash transactions, interest, capital outlays and financial assets. The monthly rate compares with the previous month directly with no seasonal adjustment.

It differs from country CPIs and from the euro-area-only MUICP. Arabic financial media use two wordings for Eurostat inflation news, one for European inflation and one for the inflation rate. The EU-wide aggregate still covers the whole Union, not the euro area alone.

Prices relate to a calendar month, with collection spread over representative days within the month. Volatile items are priced several times within the month. Old and new samples are both priced in the link month for chaining.

The euro-area flash, an early estimate, appears at the end of the reference month. The full EU, euro-area and country set follows around the middle of the month after the reference month. It covers the Union, the euro area and the member states. Each release brings annual and monthly tables, aggregates and weights, contribution shares and notes.

Indices are final on release except early provisional national inputs. Flash-to-full moves are not revisions. Mistakes are corrected fast with the cause reported. Contribution shares sum allowing for rounding, with no trading signal from the publisher.

Monthly moves reflect a few broad spending groups tracked under ECOICOP, the European purpose classification. Energy and food usually lead the move. One headline can hide wide national gaps.

Country rates can fall in some states while the aggregate still rises. Tables flag estimates, provisional inputs and revised marks for revision hygiene. A falling month can sit inside a strong year, so the monthly read differs from the annual read.

• Food, alcohol and tobacco: captures grocery and food-price dynamics, split into processed and unprocessed food.

• Energy: captures fuel, electricity and gas, usually the largest headline mover.

• Non-energy industrial goods: captures manufactured goods excluding energy.

• Services: captures services prices, typically the biggest spending share and most persistent contributor.

• Memo exclusions: track all-items excluding energy, energy and food groups, or tobacco for core-like, less-volatile reads.

1. Elementary indices: combine observed prices within the smallest product group. Method varies by data source, including store checkout scanner data.

1. Laspeyres-type aggregation: average lower indices with spending weights price-updated to the link month. Weights are spending shares of 100 or per mille shares of 1000.

1. Annual chain-linking: link each link month short series onto the long series. Samples, weights and methods can update at each link. Eurostat averages still-unlinked national indices with country and category weights, with composition changes entering through the chain formula.

1. Monthly rate: given-month index over prior month minus 1 times 100 gives the monthly rate.

1. Annual rate and contributions: same-month prior-year comparison gives the annual rate. Monthly share equals component change times its price-updated weight. Annual shares use additive Ribe maths, a summing method, allowing rounding.

1. Re-referencing and policy: the long series is rebased to 100 about every 10 years without changing rates apart from rounding. European aggregates carry two decimals while news releases show one decimal. The publisher states a 2% medium-term policy aim and gives no trading signal.
