Transparency International's 2025 Corruption Perceptions Index reveals a complex global landscape where established democracies face unprecedented challenges while emerging economies show remarkable progress, painting a stark picture of governance trends across 182 countries worldwide.
The comprehensive annual rankings, released February 10, 2026, demonstrate that corruption remains a persistent threat to democratic institutions globally, with more than two-thirds of countries scoring below 50 points on the 100-point scale where 100 represents "very clean" and 0 means "highly corrupt."
Bottom Rankings Highlight Systemic Failures
Afghanistan's position at 169th out of 182 countries with only 16 points underscores the severe governance challenges under Taliban control. The country's decline marks another step backward from recent years, reflecting what experts describe as worsening institutional capacity and transparency.
South Sudan and Somalia occupied the bottom positions as the most corrupt nations globally, according to the index. South Sudan's persistent ranking at the bottom reflects ongoing challenges in state-building and governance following years of civil conflict.
Venezuela maintained its position as the third most corrupt country worldwide with just 10 points, demonstrating that despite recent political changes, systemic corruption issues remain deeply entrenched in the country's institutions.
"The results show that more than two-thirds of countries worldwide have scores below 50, indicating that corruption systemically undermines institutions globally."

Western Balkans Face Serious Stagnation
The Western Balkans region experienced what Transparency International's Lidija Prokic characterized as "serious stagnation" in tackling corruption. Bosnia and Herzegovina scored 34 points, ranking 109th globally, placing it among countries where corruption systematically undermines institutions.
Serbia performed even worse in the regional comparison, though specific rankings were not disclosed in available reports. The stagnation reflects a broader challenge across the Western Balkans where anti-corruption drives have faltered despite European Union integration aspirations.
This regional trend contrasts sharply with EU requirements for judicial reform and anti-corruption measures as prerequisites for membership negotiations, creating significant obstacles for countries seeking European integration.
Mixed European Performance
European Union member states showed varied results, with some countries experiencing concerning declines. Belgium faced warnings about gradually increasing corruption, with Transparency International noting that the country's position among least corrupt nations is not improving.
"The fundamental principles of good governance, the public interest, equality and justice are being trampled underfoot."

Slovenia dropped two points to 58 out of 100, falling five places to 41st globally compared to its 36th position in 2024. Despite remaining above regional averages, the decline signals concerning trends in what was previously considered a stable institutional environment.
Romania continued to rank among the lowest three EU member states with 45 points, alongside Bulgaria and Hungary (both at 40 points). The country remains below the average of fragile democracies, which stands at 47 points, highlighting persistent challenges in institutional reform.
Notable Success Stories
Estonia demonstrated stability by maintaining its 12th place globally, tying with Australia, Hong Kong, and Ireland. The country's consistent high ranking reflects sustained commitment to transparency and good governance practices.
Greece showed modest improvement in addressing corruption phenomena compared to the previous year, representing progress in a challenging global environment where many countries experienced declines.
Moldova achieved a respectable 80th position globally with 42 points, demonstrating that smaller countries can make meaningful progress through dedicated reform efforts and international cooperation.
Middle East and Developing Nations
Kuwait maintained stability at 65th place with 46 points, unchanged from 2024 despite the index expanding to include 182 countries from 180. This consistency reflects institutional stability amid regional challenges.
The performance demonstrates that countries can maintain their relative positions even in an expanding global assessment, suggesting sustained governance standards despite broader regional pressures.
Latin American Challenges
Brazil experienced one of its worst performances since tracking began in 2012, scoring just 35 points and remaining at 107th position. The decline was attributed to scandals affecting all three branches of government, including the INSS pension fraud and Banco Master banking scandal.
The country's struggles with corruption span executive, legislative, and judicial branches, representing systemic challenges that require comprehensive institutional reform rather than isolated interventions.
Methodology and Global Trends
The Corruption Perceptions Index measures perceptions of corruption in the public sector by aggregating data from 13 independent sources, including surveys of businesspeople and country experts. The methodology ensures comprehensive assessment across diverse governance contexts.
Countries with strong democracies averaged 71 points, with none scoring below 50. In contrast, fragile democracies recorded an average of just 47 points, highlighting the correlation between democratic institutions and corruption control.
Eastern Europe and Central Asia remain among the world's most challenging regions for corruption control, with persistent institutional weaknesses undermining governance effectiveness across multiple countries.
Implications for Foreign Investment
The rankings carry significant economic implications, as declining corruption scores correlate with reduced foreign investment. International investors increasingly view corruption indices as key indicators for assessing country risk and making long-term capital allocation decisions.
Countries providing secure, transparent environments continue to attract larger international commitments, while those with governance challenges face capital flight and reduced economic opportunities.
Future Outlook
The 2025 results arrive at a critical juncture for global governance, with simultaneous democratic backsliding in established democracies and progress in select developing nations. This demonstrates that outcomes are not predetermined and can be influenced through sustained political commitment to transparency.
Enhanced international cooperation for anti-corruption efforts is emerging as essential, particularly for addressing transnational criminal networks and ensuring robust vetting procedures for high-level appointments.
Success in corruption control requires sustained political commitment across electoral cycles, institutional capacity building, civil society protection, and coordinated international support for transparency initiatives. The 2025 index serves as both a warning about democratic fragility and evidence that progress remains possible through dedicated reform efforts.
