UN on brink of total collapse, Guterres warns as US funding crisis deepens

The United Nations is facing an “imminent financial collapse” that could see it run out of cash by July, Secretary-General António Guterres has warned, as the organization grapples with a catastrophic funding shortfall driven largely by the United States withholding billions in dues .

In an urgent letter to ambassadors, Guterres stated that the integrity of the entire multilateral system is at risk. He presented member states with a stark ultimatum: pay their mandatory dues in full and on time, or fundamentally overhaul the financial rules to prevent a total system failure .

“I cannot overstate the urgency of the situation we now face,” Guterres wrote. “We cannot execute budgets with uncollected funds, nor return funds we never received” .

‘Kafkaesque’ Financial Trap

The crisis has been triggered by a record $1.57 billion in unpaid dues from 2025, a figure more than double the previous year’s arrears . While the Secretary-General did not explicitly name Washington in his letter, the diplomatic target was clear.

The United States, historically the UN’s largest financial backer, has refused to contribute to the regular and peacekeeping budgets for the current fiscal year. According to UN officials, the US currently owes approximately $2.2 billion to the core budget, plus an additional $2.4 billion for peacekeeping operations .

Guterres highlighted a “Kafkaesque cycle” in the UN’s financial rules that requires the organization to return hundreds of millions of dollars in unspent funds to member states—even if the UN never actually collected that money in the first place . Just this month, the UN was compelled to return $227 million to member states that it does not have in hand .

“In other words, we are trapped,” Guterres said, “expected to give back cash that does not exist” .

Operational Meltdown

The liquidity crisis is no longer just a budgeting issue at headquarters; it is having lethal consequences on the ground. With cash reserves expected to be exhausted by July, UN peacekeeping missions are already buckling under the strain .

The approved peacekeeping budget for 2025-26 faces a $2 billion shortfall. The UN has been forced to withdraw troops, freeze hiring, and cut patrols at a time when global conflicts are at their highest level since World War II .

In Africa, mandated cuts are resulting in the withdrawal of up to 14,000 troops and police from missions in the Democratic Republic of the Congo, South Sudan, and the Central African Republic. Pakistan, one of the largest troop-contributing nations, has warned that delayed reimbursements are affecting its ability to deploy forces .

“When a major contributor signals operational strain, it reflects systemic stress and not just diplomatic rhetoric,” wrote Ambassador Asim Iftikhar Ahmad, Pakistan’s Permanent Representative to the UN .

The crisis extends to humanitarian aid. The UN has been forced to halve its 2026 funding appeal amid deep cuts by Western donors. Tom Fletcher, the UN’s humanitarian chief, warned that the lack of funds will have a direct impact on survival: “Did your governments show up for this plan or not? The answer to that question will define who lives and who dies” .

A ‘Rival’ to the UN?

The funding collapse coincides with aggressive actions by the administration of US President Donald Trump, who has long criticized the world body for failing to live up to its potential. Washington has withdrawn from 31 UN agencies, including the World Health Organization and UNESCO, and has drastically slashed voluntary funding .

Although the US recently paid a partial sum of $160 million, it represents a fraction of the more than $4 billion owed .

Adding to the anxiety is Trump’s “Board of Peace,” a new body chaired by the US President. While a UN Security Council resolution limited the board’s scope to Gaza, Trump has suggested it could expand to handle global conflicts. Critics argue the board is designed as a rival to the UN, resembling a “colonial structure” that undermines the established multilateral order .

Guterres has warned that if the current trajectory continues, the world is not just looking at a budget crisis, but the collapse of the system of collective security built after 1945. With only 36 of 193 member states having paid their 2026 dues in full as of last week, the clock is ticking toward July .

“Either all member states honour their obligations,” Guterres concluded, “or we face the very real prospect of the financial collapse of our Organization” .
