Highest inflation rates: five economies ranked

By Invest Global ResearchPublished Updated 3 min readPublished after automated checks and an independent automated review, without a human edit
The short answerIn the World Bank annual series for 2025, Iran recorded the highest consumer price inflation at 42.2%, ahead of Turkey at 34.9%. The median across 168 economies for that year was 3.1%, and every one of the top five sits above it.

Key takeaways

The ranking

The table lists the five economies with the highest consumer price inflation in the 2025 World Bank series carried in the Invest Global dataset. The World Bank defines the measure this way: "Inflation as measured by the consumer price index reflects the annual percentage change in the cost to the average consumer of acquiring a basket of goods and services that may be fixed or changed at specified intervals, such as yearly." The series series metadata is published in the World Bank, metadata glossary: Inflation, consumer prices (annual %).

The chart data panel lists each value with its source and as-of date. The ranking covers the 168 economies that have a 2025 reading in the dataset. Economies without a reading for that period are absent, and their absence says nothing about their inflation.

How the top five compare with the median

The median of the 168 economies is 3.1%. Each economy in the table is above that figure:

The second and third entries, Turkey and Burundi, are close together at 34.9% and 34.1%. The fourth and fifth, Haiti and Malawi, are close together at 28.6% and 28.4%.

What the series shows and what it leaves out

The definition above describes an annual percentage change, so each value is one number for the period 2025. It does not show how prices moved month by month within that period, and it does not show readings after the period ended.

The ranking also leaves out every economy without a 2025 reading in the dataset. The count of 168 is a derived claim: the number of country rows with a value for the period, as recorded in the fact pack.

The values come from the World Bank series for World Bank, World Development Indicators, and the sources list at the end gives the retrieval date and link for the series.

How the ranking was built

The method is simple and reproducible. The ranking uses the World Bank consumer price series in the Invest Global dataset. The ranking uses 2025 readings only, so every entry covers the same period. The median is computed over the same set of 168 economies.

This post describes the data. It makes no statement about the causes of inflation in any listed economy. It also does not suggest that any market is a good or bad place to invest.
