Singapore: Least Corrupt in Asia Pacific, 3rd Globally

Singapore ranked as the world’s third least corrupt country in 2025, maintaining its position for the second year in a row, according to Transparency International’s Corruption Perceptions Index (TI-CPI). The nation also topped the Asia Pacific region in the index, holding a score of 84 points.

Singapore’s Consistent Anti-Corruption Ranking

Singapore has consistently been recognized for its strong anti-corruption efforts, remaining the only Asian country to be placed in the top 10 of the TI-CPI since its inception in 1995. The country previously held rankings of fifth in 2022 and 2023, fourth in 2019 and 2021, and third in 2024, 2018, and 2020.

The TI-CPI ranks 182 countries and territories based on perceived levels of public sector corruption, using a scale of 0 to 100, where 0 indicates high corruption and 100 represents a very clean system. The 2025 index is based on 13 expert assessments and business surveys.

According to the Corrupt Practices Investigation Bureau (CPIB), Singapore’s corruption situation remains “firmly under control,” evidenced by a low number of public sector corruption cases. Public perception surveys conducted by the CPIB demonstrate strong public support and confidence in the country’s corruption control efforts.

CPIB attributes Singapore’s success to “robust legislations, effective enforcement, and a vigilant society united by a shared commitment to integrity.” The bureau emphasized that a zero-tolerance approach to corruption and a collective dedication to ethical conduct are central to Singapore’s reputation as a clean nation.

In addition to the TI-CPI, Singapore was ranked first out of 16 economies in the Political and Economic Risk Consultancy’s 2025 report on corruption in Asia, the US and Australia. The country also placed second globally out of 143 countries, and first in Asia, for absence of corruption in the World Justice Project Rule of Law Index 2025.
