Tracking HIV resource availability and financing schemes to fill the gap for low- and middle-income countries and estimating countries’ resource needs for the AIDS response are cornerstones of UNAIDS’ work. The monitoring of global financing flows and in-country expenditures is conducted as part of the Global AIDS Monitoring system and monitors efforts to mobilize US$ 26 billion by 2020.

The resources available from all sources for HIV in-country activities totalled US$ 19.1 billion in 2016. This is US$ 7.2 billion lower than the resource needs estimated to be necessary by 2020 to be on track towards the end of AIDS as a global public health threat by 2030.

The trends of resource availability show that international resources have remained flat over the past few years after peaking in 2013. Domestic resources were the main upward driver, but increases appear to have slowed down in 2015–2016. Domestic sources of funds (public and private) reached 57% of the total resources available in low- and middle-income countries in 2016. This global average hides the dependence of some highly donor-dependent countries. The transition of countries is a critical area in which a concerted effort of funders, global policy-makers and country national authorities and civil society must act together.

The overall funding gap is indicative of the financing challenge ahead, but there is a need to significantly reallocate existing resources to services for populations with the highest need and with the highest impact.
