The United Nations, anticipating that President Trump will slash U.S. contributions to the global body, has told its departments to draw up plans for budget cuts, including through staff relocations from New York and Geneva to less-expensive cities.

The instructions — outlined in a two-page memo dated April 25 that was reviewed by The New York Times — were sent from Secretary General António Guterres’s office to the heads of all agencies that report directly to him. The memo set a May 15 deadline for all proposals so that they could be added to the 2026 budget.

“Your objective is to identify as many functions as possible that could be relocated to existing lower-cost locations,” the memo reads, “or otherwise reduced or abolished if they are duplicative or no longer viable.”

In February, President Trump signed an executive order calling for a review of the overall U.S. funding and ties to the U.N. He withdrew the United States from several U.N. organizations, including those dealing with human rights, women’s reproductive rights, climate change, Palestinian aid and global health. In his first term, he also reduced U.S. contributions to peacekeeping efforts.

Three senior U.N. officials said on Tuesday that the drastic, cost-cutting measures laid out in the memo had caught the agency’s departments by surprise and went beyond what they had expected. The officials, who requested anonymity because they were not authorized to speak publicly, said the directive was largely viewed as a way for the U.N. to brace for potential additional cuts by Mr. Trump and to proactively insulate it from the financial blow.

But the U.N. officials said the budget cuts were ordered only partly in response to Mr. Trump’s moves. The directive comes as the U.N. is adjusting to a host of financial problems, they said, from the withdrawal and reduction in financial contributions by major donors like the United States and Europe to a cash-flow crisis caused by member states’ not paying their annual dues on time and in full.
