Which are the least corrupt countries worldwide?
The CPI ranked 180 countries based on their perceived levels of public sector corruption. Singapore retained its highest position on the CPI scale report since 2020, with a score of 84 out of 100. Zero represents high corruption and 100 indicates a very clean public sector according to the report.
Globally, Singapore holds the spot as the world’s third least corrupt nation, just behind Denmark and Finland. In fact, Denmark retained its position as the least corrupt country globally for the eight year in a row.
Singapore’s ranking as the third least corrupt country worldwide and the no.1 least corrupt country in Asia-Pacific can be attributed to many factors. For instance, the country’s robust anti-corruption framework, strong enforcement mechanisms, cultural integrity, and strict police force is the reason for its success in combating corruption. Meanwhile, The Corrupt Practices Investigation Bureau (CPIB) highlighted that the nation’s zero-tolerance approach to corruption and willingness to prosecute offenders (regardless of positions of power) is pivotal.
