Corruption in Thailand
Institutional corruption in the country
Corruption in Thailand is a national issue. Thai law provides criminal penalties for conviction of official corruption. Thailand's 2014 military junta, the National Council for Peace and Order (NCPO), stated that fighting corruption would be one of its main focus points, a common practice for military dictatorships following Thailand's frequent military coups. Despite the promises, officials engaged in corrupt practices with impunity, and the NCPO engaged in corrupt practices itself.
Transparency International's 2025 Corruption Perceptions Index, which scored 182 countries on a scale from 0 ("highly corrupt") to 100 ("very clean"), gave Thailand a score of 33. When ranked by score, Thailand ranked 116th among the 182 countries in the Index, where the country ranked first is perceived to have the most honest public sector. For comparison with regional scores, the best score among those countries of the Asia Pacific region that appeared in the Index was 84, the average score was 45 and the worst score was 15. For comparison with worldwide scores, the best score was 89 (ranked 1), the average score was 42, and the worst score was 9 (ranked 181, in a two-way tie).
"Even though Thailand has the legal framework and a range of institutions to effectively counter corruption, all levels of Thai society continue to suffer from endemic corruption."
In the 2022 edition of its Best Countries rankings, U.S. News & World Report evaluated global perceptions of 85 developed countries based on 73 country attributes. On the country attribute "Not Corrupt", countries were scored on a scale from 1 to 100 and then ranked by score.

Why this record matters
The phrase “institutional corruption in the country” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q18349000. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014, 2025 and 2022.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
