• Zimbabwe's health budget shifts source every year: government, donors and households all take turns carrying the largest share, and none of them hold it for long.
• Three donors, the Global Fund, USAID/PEPFAR and the CDC, have supplied most external health financing since 2021, and that funding has now shrunk by more than half.
• Households are absorbing the gap through out-of-pocket payments, a trend that raises the risk of catastrophic health spending for ordinary families.

Harare- Zimbabwe's health sector runs on money that arrives from a different direction every year. Government pays a large share one year and a small share the next. Donors step in when domestic funding falls short, then pull back when their own priorities shift. Households cover whatever remains through fees paid directly at the point of care. This pattern shows up clearly in the National Health Accounts data covering 2021 to 2024, and it tells a story that goes beyond simple underfunding. The problem is not only that Zimbabwe spends too little on health. The deeper problem is that no funding source can be counted on to behave the same way twice.

Government's own contribution to the health budget swung from 39.2 percent in 2021 down to 13.8 percent in 2023, then back up to 33.6 percent in 2024. That is not a gradual decline or a steady climb. It is a sharp drop followed by a sharp recovery, the kind of swing that makes multi-year planning difficult for hospital administrators and impossible for private suppliers trying to forecast government demand. Donor financing moved in the opposite direction over the same years, rising from 35.6 percent in 2021 to a peak of 43.5 percent in 2023, then falling to 25.3 percent in 2024. When government pulled back, donors filled part of the gap. When donors later reduced their share, government had already begun paying more again. The two sources appear to move in response to each other rather than as part of any coordinated financing plan.

Households absorbed much of the pressure created by this back and forth. Out-of-pocket payments and corporate medical scheme contributions rose from 19.8 percent of the health budget in 2021 to 30.4 percent in 2023, before easing slightly to 23.4 percent in 2024. That increase matters because out-of-pocket spending is the least protective way to finance health care for any population. Families paying directly for consultations, medicines and hospital stays face the highest risk of catastrophic expenditure, defined as spending more than ten percent of household income on health in a single period. Zimbabwe's own data already shows catastrophic expenditure affecting close to twelve percent of all households, and nearly nineteen percent of households in urban areas specifically.

The external side of the ledger deserves its own scrutiny, because a handful of donors carry an outsized share of the total. Between 2021 and 2023, the Global Fund, USAID/PEPFAR and the CDC together accounted for the bulk of roughly 500 million dollars in annual partner contributions to Zimbabwe's health sector. That combined figure held reasonably steady across those three years, giving the appearance of a dependable financing base. The appearance did not last. By 2025, total partner contributions had fallen to 219 million dollars, a decline of more than 55 percent from the 2021 level. USAID funding, which contributed 143 million dollars in 2021, effectively disappeared from the ledger by 2025. The Global Fund and the CDC both reduced their contributions as well, though neither exit was as abrupt as USAID's.

This concentration among so few donors creates a single point of failure risk that any analyst covering African health financing would recognize immediately. Programs built around HIV treatment, tuberculosis diagnostics and malaria control have depended heavily on these specific funding streams for over a decade. When one donor exits at the scale USAID has, the programs it once supported do not simply shrink gradually. They face an immediate funding cliff that domestic revenue has not been positioned to fill. Zimbabwe's own health financing strategy acknowledges this exposure directly, calling for the country to manage a transition away from donor dependence toward more sustainable domestic sources. The strategy names the right problem. Whether the country can mobilize the domestic revenue needed to solve it within the next few years remains an open question, given that government's own health spending has already proven volatile even without accounting for donor withdrawal.

The health system responded to previous donor contractions by leaning more heavily on ring-fenced domestic mechanisms such as the AIDS Levy, a tax collected from workers and companies that has become one of the more reliable sources in the entire financing picture. That reliability stands out precisely because it is so rare elsewhere in the ledger. Most domestic revenue tools introduced in recent years, including taxes on airtime, data and sugar-sweetened beverages, still lack the transparency needed to confirm whether the money collected actually reaches health facilities or simply substitutes for funding that government would have provided regardless. Without that transparency, it becomes difficult for anyone outside government, including the donors being asked to reduce their role, to judge whether domestic financing is truly expanding or merely being repackaged under a new label.

What emerges from this data is a financing system held together by improvisation rather than design. Each source compensates for the others in an ad hoc way, and the compensation itself is unpredictable from one year to the next. For a country trying to build toward universal health coverage, that instability may matter more than the overall funding shortfall. A health system can adapt to being underfunded if the shortfall is at least predictable. Zimbabwe's health sector faces a harder task: adapting to funding that is both insufficient and unpredictable at the same time, arriving from whichever source happens to have capacity in a given year, and leaving households to absorb whatever gap remains.
