2026 Aid Transparency Index: World’s three biggest aid donors fall back on transparency, while multilaterals lead the way
The 2026 Aid Transparency Index shows that the three largest aid providers – Germany, the US and the UK – have become less transparent in the last two years. However, most of the world’s leading aid and development agencies are still publishing good-quality information, after the steepest fall in aid on record. Multilateral organisations lead the way, and Spain makes the biggest improvement in the Index’s history.
