Summary
- HIV resources available for low and middle income countries (L&MICs) fell to USD 17.6 billion in 2025, down from a peak of USD 19.6 billion in 2020.
- The 2025 figure is USD 4.3 billion short of the USD 21.9 billion needed annually to stay on track to end AIDS as a public health threat by 2030.
- International HIV funding recorded its largest single-year decline in nearly two decades in 2025, even as domestic contributions continued to grow.
Statiatical Analysis
UNAIDS 2026 financial estimates show that HIV resources available for L&MICs grew from USD 15.6 billion in 2010 to USD 18.9 billion in 2015, and reached a peak of USD 19.6 billion in 2020. This period of sustained growth coincided with the most rapid expansion of antiretroviral treatment in history, with the number of people on ART rising from 7.6 million in 2010 to 26.3 million by 2020.
After 2020, however, the funding trend reversed. Resources declined to USD 18.8 billion in 2024 and fell further to USD 17.6 billion in 2025. This represents a drop of USD 2.0 billion, or approximately 10%, from the 2020 peak in just five years. When measured against the USD 21.9 billion that UNAIDS estimates is needed annually by 2030, the current shortfall stands at USD 4.3 billion, or roughly 20% of the required investment.
The 2025 decline is particularly concerning because of its composition. Total international resources for HIV fell by 18% in 2025, the largest annual decline in almost two decades. Domestic funding from L&MIC governments did increase by approximately 4% in the same year, and more than 55 countries have since announced plans to raise their HIV budgets. However, domestic growth was not large enough to offset the international reduction, and the net result was a significant contraction in total available resources.
The funding gap is not abstract. Every billion dollars below the required threshold translates directly into fewer people on treatment, slower declines in new infections, and more preventable deaths. At the current trajectory, the 2030 target of ending AIDS as a public health threat is at serious risk.
Policy Insights
The reversal in HIV funding represents one of the most serious threats to global health progress in the current decade. Urgent action is needed at both international and national levels.
- Major bilateral and multilateral donors must reverse the 18% decline in international HIV contributions and commit to the USD 21.9 billion annual target, since no domestic funding trajectory can compensate for a withdrawal of this scale.
- L&MIC governments should accelerate their own domestic HIV budget increases and ring-fence HIV funding from general austerity cuts, building on the momentum of the 55 countries that have already pledged increases.
- Global health financing bodies, including the Global Fund and PEPFAR, should work with recipient countries to improve domestic resource mobilisation frameworks so that the HIV response becomes more resilient to future international funding shocks.
