Research published in ‘The Lancet’ indicates that significant reductions in international development aid and official development assistance (ODA) could lead to millions of additional deaths by 2030. Initial reports highlight that policies such as the closure of the United States Agency for International Development (USAID) and budget cuts from nations including the United Kingdom, Germany, France, and Japan could result in 14 million additional deaths. Subsequent modeling suggests that if current defunding trends continue, approximately 7.6 million additional deaths could occur, including 1.4 million children under the age of five. To address this funding gap, researchers evaluated various fiscal redistribution policies. A 3% tax on billionaire wealth is estimated to have the highest potential impact, potentially preventing up to 29.5 million deaths. Other proposed measures include a tax on financial transactions, which could prevent 24.5 million deaths, and a global minimum tax for multinational corporations, which could prevent 20.1 million deaths. ## Timeline ### 2026-09-15: Billionaire wealth tax could prevent 29.5 million deaths by 2030 A study in ‘The Lancet’ indicates a 3% tax on billionaire wealth could prevent 29.5 million deaths by 2030 by offsetting declining international humanitarian aid. 2 sources. https://clstr.news/cluster/billionaire-wealth-tax-could-prevent-295-million-deaths-by-2030 ### 2026-09-11: USAID funding cuts could lead to millions of deaths by 2030 A study in The Lancet warns that cuts to USAID and international aid could cause millions of deaths by 2030, suggesting wealth redistribution from billionaires could mitigate the impact. 2 sources. https://clstr.news/cluster/usaid-funding-cuts-could-lead-to-millions-of-deaths-by-2030 --- Cite as: Impact of international aid funding cuts on global mortality.
