The Corruption Perceptions Index (CPI) is an index developed and published by Berlin-based Transparency International (TI), which presents a comparative picture of the extent of corruption worldwide. The comparative position of corruption in included countries is determined based on the perceptions of businesspeople, investors, researchers and analysts in related sectors regarding the prevalence of corruption in a country's politics and administration. According to the CPI, the level of corruption perception is measured on a scale from 0 (zero) to 100 (one hundred). Under this method, a score of 0 (zero) on the scale is considered to indicate the highest prevalence of corruption and a score of 100 indicates the lowest.

The 2025 CPI index was developed based on 13 internationally renowned surveys. During the CPI determination, the highest internationally recognized standards and special precautions are taken in collecting and analyzing survey data. Additionally, TI reviews in detail the sources of all survey data used, as well as the data collection methodology of each survey, to ensure that the data sources are consistent with TI's standards.

This year, data from eight surveys were used as sources for Bangladesh. The surveys are: World Bank's Country Policy and Institutional Assessment, World Economic Forum Executive Opinion Survey, Global Insight Country Risk Ratings, Bertelsmann Foundation Transformation Index, World Justice Project Rule of Law Index, Political Risk Services International Country Risk Guide, Economist Intelligence Unit Country Risk Ratings, and Varieties of Democracy Project Dataset reports.

TIB plays no role in formulating the CPI. Even no data or analysis obtained from TIB's research is sent to TI. The same applies to TI chapters in other countries around the world. Like TI chapters in other countries, TIB only publishes the CPI at the national level.

According to CPI 2025, the global average score out of 100 is 42, while Bangladesh's score is 24—which is 18 points lower than the global average score and 21 points lower than the Asia Pacific region's average score of 45. Bangladesh's score is the second lowest in the last 14 years, similar to 2023. Bangladesh's position in the Corruption Perceptions Index is evidence of the prevalence of corruption in the country.
