World Inflation Rate (CPI)

Primary source

All values come directly from World Bank (FP.CPI.TOTL.ZG). We do not modify, smooth, or interpolate published values.

Global consumer price inflation rate, percent change year-over-year. Aggregated across all World Bank member countries. Useful context for comparing domestic inflation to the global environment.

Update schedule

Annual — we refresh daily; most recent value typically lags 1-2 years on upstream.

We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
