The Trump administration has secured more than $1 billion in cuts to United Nations budgets over the past six months, marking what U.S. officials describe as an unprecedented push to reform an institution long considered resistant to change. The latest milestone came on June 30, when all 193 U.N. member states approved a peacekeeping budget of approximately $5.1 billion for the coming fiscal year — about $550 million, or 9.7%, less than the previous year. Combined with a 15% reduction to the U.N.'s regular budget approved in December, U.S. officials say the agreements amount to more than $1 billion in cuts to assessed U.N. budgets, a level they characterize as historic.
Assessed budgets are funded through mandatory contributions charged to member states under a formula based largely on the size of their economies. The United States is the largest contributor, paying about 22% of the regular budget and roughly 27% of peacekeeping costs. U.S. Ambassador for U.N. Management and Reform Jeff Bartos told Fox News Digital that the cuts demonstrate the effectiveness of sustained American pressure. "On June 30th, with U.S. leadership, all 193 countries came together again for the second time in six months," Bartos said. "We've achieved over a billion dollars of savings in six months, which is unprecedented. Any one cut would be unprecedented. The totality of the reforms is monumental."
The agreement comes as the United Nations faces mounting financial pressure and prepares for a leadership transition in 2027, with Secretary-General António Guterres set to leave office at the end of his second term. The Trump administration has made reform a central pillar of its U.N. strategy, arguing the organization has become overly bureaucratic and inefficient. In response to questions from Fox News Digital, U.N. spokesman Stéphane Dujarric confirmed that the peacekeeping budget was reduced by roughly $550 million and the regular budget by 15%, describing both as "unprecedented reductions."
Bartos argues the reforms reflect sustained pressure from the Trump administration and months of negotiations led by the U.S. Mission. "The new budget, this reformed budget, the enhanced efficiency changes the culture of how the U.N. looks at peacekeeping," Bartos said. "Every dollar has to achieve impact on the ground." He pointed to the U.N. Mission in South Sudan as an example, saying the United States worked to streamline the mission's mandate before reducing its budget accordingly. The administration has also highlighted changes to how the U.N. handles unused budget credits. Until now, U.N. financial rules required the organization to return unspent funds to member states even if those contributions had never actually been paid, a practice critics said worsened the organization's recurring liquidity crisis.
The General Assembly voted on June 30 to introduce, on a four-year trial basis, a new methodology under which unspent funds will be returned only when backed by cash actually received. Bartos said the change could save the organization more than $1 billion over the next three years. That projected figure is separate from the more than $1 billion in budget reductions already approved over the past six months. He called the change another example of "common-sense" reform. The United Nations likewise welcomed the change, though officials noted it had been a long-standing priority of Guterres. "I have been pushing for this reform for almost a decade," Guterres said after the vote. He described the previous system as a "Kafkaesque cycle" in which the organization was expected "to give back cash that did not exist." Dujarric said the reform would allow the U.N. to manage resources "in a more predictable and responsible way" while helping ensure operational continuity, particularly for peacekeeping missions.
Bartos insists the latest budget agreements are only the beginning. Among the administration's next priorities are reforms to staff compensation, employee benefits and the U.N. pension system, areas he argues consume resources that could otherwise support humanitarian operations and peacekeeping missions. "We're going to continue to see us push whether it's on benefits, whether it's on staff compensation, whether it's on the pension system," Bartos said. "There's massive numbers of additional reforms that our team is working on right now." He also suggested reform will remain a central issue as member states begin selecting the next secretary-general. "We're going to select the next secretary-general," Bartos said. "That reform momentum that has been growing over the last 15, 18 months... you'll see that continuing in 2027 with the new secretary-general."
The developments signal a significant shift in U.N. budget dynamics, with the United States leveraging its position as the largest donor to push for greater efficiency and accountability. Critics of the U.N. have long argued that its budgeting processes lack transparency and that mandatory contributions create little incentive for cost control. The Trump administration's approach has been to tie continued U.S. funding to concrete reforms, a strategy that appears to have gained traction among other member states facing their own fiscal pressures. The peacekeeping budget reduction alone represents a notable change, as peacekeeping operations have historically been a major source of tension between the U.S. and other member states over cost-sharing and mandate clarity.
