How is ODA from the US changing over time?

The US was the largest donor country in absolute terms in 2024. As a result of expected ODA cuts under the Trump administration, the US' ranking in both relative and absolute terms is expected to fall in subsequent years.

The US once again withdrew from the Paris Agreement and WHO upon Trump's inauguration in January 2025, and has since reduced or terminated funding for several other multilateral organizations.

On July 1, 2025, the American government officially closed USAID with the Department of State now overseeing all foreign assistance distribution. Since the closure of USAID, many programs have been halted or scaled down immensely, some grants for HIV and tuberculosis medications, and food assistance for countries in civil wars and natural disasters have continued.

Despite the drastic nature of US ODA cuts, the FY26 International Affairs budget is US$20.4 billion, or 66%, above the Trump Administration's budget request.

The US aligns with the DAC statistical directives and ODA definition. However, the US' definition of 'foreign assistance' is broader and includes non - ODA eligible items such as military assistance, although there are significant gaps in Department of Defense reporting. The difference between ODA and foreign assistance reporting is highlighted in this table.
