List of countries by inflation rate

This is the list of countries by inflation rate. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. Inflation rate is defined as the annual percent change in consumer prices compared with the previous year's consumer prices. Inflation is a positive value in the inflation rate and means a general decrease in purchasing power for the domestic currency in the country in question and a general increase in prices of goods and services compared to the currency—if the inflation rate is negative, that indicates deflation, a general decrease in prices of goods and services traded for a country's domestic currency.

According to World Bank, ″the Consumer price index reflects changes 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 Laspeyres formula is generally used. Data are period averages.″^[2]

According to United Nations Conference on Trade and Development, ″the Consumer Price Indices (CPI) is an inflationary indicator that measures the weighted average of prices of a basket of consumer goods and services, purchases by a consumer. The CPI is calculated by taking price changes for each item in the predetermined basket of goods and services during a month. Changes in CPI are used to assess price changes associated with the cost of living.″^[3]
