The United States have long been the most important contributor to overall UN budgets and thus hold considerable financial power across the UN system. The second Trump administration is likely to cut funding and excessively prioritize earmarked contributions over the provision of core resources, which is set to exacerbate the growing misalignment of funding modalities and expected UN functions. Member states should embed short-term measures focused on mitigating the liquidity crisis in the UN Secretariat and funding shortfalls elsewhere in the UN system in longer-term strategic thinking about the refinement of UN roles and funding structures.
