Overview
Thailand's control of corruption stood at -0.48 in 2025, a rise of +0.01 from 2023. Based on recent trends, this figure is projected to reach -0.48 by 2025. Thailand ranked 128th globally.
Thailand’s score on the World Bank’s Control of Corruption index has slipped from a modest –0.36 in 1996 to –0.48 in 2025, placing the country at 128th position worldwide. The indicator reached its highest point in 1998 at –0.14, suggesting relatively better perceived integrity at the turn of the millennium, but then fell into a persistent decline that culminated in an all‑time low of –0.56 in 2015. Over the 26‑year coverage period, Thailand’s trajectory has mirrored that of several peers, notably Trinidad and Tobago (–0.48) and Guyana (–0.48), which occupy similar rankings in the latest release. The long‑run deterioration implies that reforms aimed at strengthening institutional checks, enhancing transparency in public procurement, and improving whistle‑blower protection could be pivotal in reversing the downward swing and moving Thailand toward a more favorable corruption perception in future assessments.
