Thailand’s score was on par with three other countries: Ecuador, Panama and Serbia. In the past decade, the best CPI score Thailand has achieved was 38, in both 2014 and 2015. The three worst performers in the 2025 survey were Venezuela with a score of 10 points, Somalia and South Sudan (9 each). Berlin-based Transparency International said the global average score in 2025 dropped one point to 42, and 122 countries scored below 50, signalling widespread public sector corruption. Countries that curb civic space often lose control of corruption, Transparency International said.
