WASHINGTON — The Inter-American Development Bank (IDB) improved its score in the 2026 Aid Transparency Index, reaffirming its position as a leader in transparency among major international development organizations and maintaining second place globally.
The IDB's score in the Aid Transparency Index increased to 97.1 in 2026 from 96.3 in 2024, reflecting its continued commitment to transparent and accountable reporting. The Index, published by Publish What You Fund every two years, is widely recognized as the global benchmark for transparency in development finance.
“Transparency and development impact go hand in hand. By making information more accessible and systematically reporting our results, we strengthen accountability, build trust among stakeholders, inform better decisions, and support more effective development outcomes for the countries and communities we serve,” said IDB Group President Ilan Goldfajn.
The IDB’s strong performance this year reflects the successful implementation of the Bank’s new Access to Information Policy. In effect since 2025, the policy has strengthened the Bank’s proactive disclosure approach. As of December 2025, the IDB had disclosed 19,190 documents, a 19% increase compared with 2024.
In addition, the policy reduced the exceptions to disclosure from 10 to 6, introduced a harm test analysis, which uses objective criteria to determine when information should be protected, and strengthened its governance framework supporting the implementation of the policy.
The Aid Transparency Index assesses the transparency of major development finance institutions based on their disclosure of information under the International Aid Transparency Initiative (IATI) Standard.
The IDB has been an IATI signatory since 2011 and reports standardized data every month on more than 2,000 sovereign-guaranteed operations approved since 2004. The data allows governments, partners, and citizens to compare and coordinate development financing across the region.
