Inflation Rate by Country 2026

Executive summary

This index ranks 49 of the world's largest economies by inflation (CPI), using World Bank Open Data for cross-country comparability, and goes beyond a single snapshot: it shows the nominal figure, a ten-year history, a regional breakdown and the biggest movers. Argentina leads at 219.9% (2024); Thailand is lowest among those ranked at -0.1%. Sweden ranks 45th of 49 at 0.7% (2025). As reference points, the EU stands at 2.5%, the OECD at 2.8% and the world at 3.0%. Every figure carries its World Bank series and reference year, and the complete dataset is free to download as CSV and JSON under a CC BY 4.0 licence.

Key findings

Overview

Inflation — the annual percentage increase in consumer prices — erodes the purchasing power of money and is the primary target of central banks, most of which aim for around 2%. This index ranks countries by their most recent annual consumer-price inflation.

The spread is enormous: a handful of crisis economies run inflation in the tens or hundreds of percent, while most advanced economies have brought inflation back down from the 2022–2023 shock toward target. The trend table below shows how far each has travelled.

What drives the ranking

Inflation is driven by the balance of demand and supply, the money supply, exchange-rate pass-through to import prices, energy costs and inflation expectations. Runaway inflation is almost always a monetary and fiscal phenomenon — governments financing deficits by printing money.

For most of the countries in this index, the recent story is disinflation: the post-pandemic surge has faded, and central banks are shifting from raising rates to holding or cutting them.

How it has changed over time

The chart tracks inflation (CPI) for Argentina (the current leader) against Sweden over the past decade; the table below shows the top economies year by year.

By region

Median inflation (CPI) by world region among the ranked economies. Regional medians reveal patterns the country ranking alone can hide.

Biggest movers

The largest changes in inflation (CPI) over the available window — where the action has been.

Methodology & verification

Economies are ranked by inflation (CPI) using the World Bank Open Data API, which harmonises national statistics for cross-country comparison. Each value is the most recent year available for that economy, shown alongside the figure; the trend table uses each economy's reported history. Economies with no reported value are omitted rather than estimated. Region aggregates (EU, euro area, OECD, World) are reference points, not ranked. National consumer-price indices use different baskets and methods, so cross-country comparison is approximate; the internationally harmonised measures (e.g. HICP in the EU) can differ from the national CPI shown here. Confidence: High (official multilateral source).

Frequently asked questions

Glossary

Inflation (Cpi)

Inflation, consumer prices (annual %) — as reported by the World Bank. ↗

World Bank Open Data

A free, authoritative database of harmonised economic indicators for every country. ↗

Purchasing-power parity (PPP)

A conversion that equalises the price of a comparable basket of goods across countries, so output and incomes can be compared in real terms rather than at market exchange rates. ↗

Nominal (current US$)

A value converted at prevailing market exchange rates and not adjusted for differences in price levels. ↗

GNI per capita

Gross national income per person — like GDP per capita but including net income earned abroad; useful where cross-border corporate flows are large. ↗

Reference year

The year a figure applies to; it can differ across countries because national statistics are published on different schedules. ↗

Region aggregate

A World Bank grouping (e.g. European Union, OECD, World) whose value is a weighted regional total or average, shown here for reference rather than ranked. ↗
