Weeks after President Donald Trump withdrew the US from dozens of United Nations organizations, the UN’s chief warns that the UN is at risk of an “imminent financial collapse.”
“The crisis is deepening, threatening program delivery and risking financial collapse. And the situation will deteriorate further in the near future,” UN Secretary-General António Guterres wrote in a letter to ambassadors dated January 28, according to a Friday report from Reuters.
While he did not reference the United States explicitly, Guterres called out the fact that “decisions not to honor assessed contributions that finance a significant share of the approved regular budget have now been formally announced,” which almost certainly referenced Trump’s pullout from at least 66 international treaties earlier this month, including 31 within the UN system.
With the stroke of a pen, Trump reneged on the US commitment to the UN Framework Convention on Climate Change, which it has been part of for more than 30 years. He also took the US out of the UN International Law Commission, the UN Democracy Fund, UN Oceans, UN Women, and dozens of other global bodies, deeming them “contrary to the interests of the United States.”
As the world’s largest economy, the US was the largest source of funding for the UN, providing 22% of its regular and peacekeeping budgets as of 2025—about $820 million per year.
The largest single financial cut as a result of the US pullout was the termination of dozens of grants worth approximately $377 million for the UN Population Fund, which focuses on family planning and preventing maternal mortality and sexual violence in developing nations. The organization is estimated to have prevented 39,000 maternal deaths and 18 million unwanted pregnancies in 2024, according to an annual report.
Warning that cash could run out by July, Guterres said, “Either all member states honor their obligations to pay in full and on time–or member states must fundamentally overhaul our financial rules to prevent an imminent financial collapse.”
