World · Inflation, Average Consumer Prices, IMF Projection

## What this measures

Consumer prices, annual average, percent change from the year before. World (an IMF aggregate).

## Why it matters

Inflation decides how far central banks tighten or ease and how much of nominal growth is real. The IMF publishes one comparable measure, with forecasts, for nearly every economy.

## How to read it

An annual average, so it moves more slowly than the twelve-month rate national agencies publish each month. Aggregates weight countries by GDP at purchasing-power parity.

Each point is a calendar year, dated December 31. The first three points are the years before the WEO's own year, as published in that WEO (estimates and outturns, flagged forecast = false), so the line joins the history. From the WEO's own year on, every point is an IMF forecast (flagged forecast = true). Every point carries the WEO edition it comes from (vintage). The whole path is replaced when a new WEO is published, in April and October. Palanor does not compute statistics or records on this series and does not project it further.

## What it does not say

Forecasts assume current policies. A few countries in very high inflation can swing the aggregates; the IMF excludes some from regional averages, as each WEO notes.
