"The United States has long held the position of the world’s single largest donor to humanitarian aid, a fact clearly illustrated by data from the UN’s Financial Tracking Service (FTS). In 2024, the US contributed a staggering $13.80 billion to humanitarian efforts globally, representing 43.04% of the total funding tracked by the FTS. This figure is not only immense in absolute terms but also dwarfs the contributions of other major donors. In fact, as detailed in FTS data, US contributions in 2024 were greater than the combined contributions of the next ten largest donors [...] This overwhelming dominance of US funding has created a global humanitarian ecosystem that is heavily reliant on a single source. While the US’s generosity has undoubtedly saved countless lives and alleviated immense suffering, it has also created a precarious situation. The humanitarian sector’s dependence on a single actor makes it extremely vulnerable to shifts in US political priorities and domestic policy – as we are seeing now. The executive order to freeze virtually all US foreign aid, therefore, is not merely a budget adjustment; it is a seismic event that threatens to destabilize the entire humanitarian system. The sudden stop-work order on USAID contracts and grants effectively severs a vital lifeline, leaving organizations scrambling and exposing the fragility of a system built on this substantial, yet now uncertain, foundation."
