António Guterres’s decade at the helm of the United Nations closes with the organisation confronting unprecedented strains. His tenure produced notable initiatives—the 2022 Black Sea grain deal and a push for more women in senior UN roles—but those achievements sit alongside mounting humanitarian crises, budgetary pressure and stalled diplomacy that critics say left the world body diminished.
The international context that framed Mr Guterres’s term was unusually fraught: analysts count some 65 active armed conflicts globally, the highest since 1946, and wars involving major powers have tested the core legal framework that underpins multilateral action. The authority of the UN Security Council has been repeatedly challenged, while accelerating climate change and the disruptive potential of artificial intelligence have added new, cross-border risks. For legal reference, the UN’s founding text remains central: the UN Charter.
On policy and operations, the office sprouted both diplomatic wins and visible shortcomings. Guterres brokered the Black Sea Grain Initiative, elevated women across UN leadership ranks and pressed climate diplomacy. Yet the organisation also faced deep fiscal strain after major arrears from a key member left the UN with roughly US$4 billion unpaid, forcing austerity measures and staff cuts. The reform effort launched as UN80 aimed to streamline operations but resulted in job losses and raised concerns about diminished capacity to respond to humanitarian shortfalls.
Guterres’s earlier record as Portugal’s prime minister and as head of the UN refugee agency informed expectations that he could modernise the institution; the UN refugee statistics show global displacement rising from around 65.6 million to roughly 118 million during his years in leadership. As he prepares to leave, the organisation he led faces questions about its ability to protect civilians, prevent large-scale violence and marshal predictable funding. The transition to a new secretary-general will test whether the UN can translate its stated ambitions into stronger, more effective action in a more fragmented world.
