South Africa’s Deficit Narrows to 3.9% as Tax Revenue Rises by 17.1 Billion Rand
Key Facts
South Africa’s finance ministry expects the budget deficit to narrow to 3.9% of GDP in fiscal year 2026/27, compared with an estimate of 4.0% in the February budget. Finance Minister Enoch Godongwana said the Treasury raised its estimate of gross tax revenue for the year by 17.1 billion rand from its previous estimate. The ministry attributed the increase to higher collections from corporate income tax, dividends tax and value-added tax. The deficit revision comes as the Treasury announced that debt to GDP had stabilized at 78.4% in 2025/26, for the first time in nearly two decades. This strengthens signs of fiscal consolidation, while the government’s ability to keep the trajectory on track remains contingent on sustained revenue and stronger economic growth.
But improved collections do not all reflect a lasting expansion of the tax base: the Treasury said a large part of the increase was due to higher commodity prices, and those gains are expected to fade over the medium term. This reliance on external factors limits confidence in the upward revision to revenue. Meanwhile, the ministry cut its forecast for real economic growth in 2026 to 1.2% from 1.6% in its February estimate, and expects growth of 1.6% in 2027. The February budget had forecast growth of 1.6% in 2026, rising to 2% by 2028. Weaker growth makes it harder to reduce the deficit through revenue alone, and makes spending discipline and productivity improvements essential to the debt trajectory.
Moody’s expects general government debt to have peaked at 86.8% of GDP in 2025, before gradually declining to 84.9% by 2028. This measure differs from the debt ratio announced by the Treasury, as the agency’s estimate includes most guarantees to state-owned companies. Nor does the projected decline in the ratio remove the burden of servicing it: interest payments amounted to 18.8% of general government revenue in 2025. Moody’s said this ratio was weaker than that of South Africa’s similarly rated peers. In an earlier assessment, the agency forecast the primary surplus would rise to 1.8% of GDP in 2027, above the 1.5% it estimated was needed to stabilize debt; the Treasury, meanwhile, aims to raise its primary surplus from 1.7% in the current year to nearly 3% by 2030.
Moody’s kept South Africa’s sovereign rating at Ba2 in May, while changing its outlook to positive from stable. Before the budget statement, the agency said an upgrade would require sustained fiscal discipline and stronger growth, and that the medium-term budget and the next budget would test the improvement’s ability to reduce debt on a sustained basis. A Moody’s vice president of ratings said strengthening the fiscal framework during an election cycle could preserve some of the fiscal gains. The agency linked medium-term growth potential to continued reforms in electricity, logistics and water, saying these could raise potential growth to above 2% and help attract private investment. The credit assessment therefore remains contingent on the government’s ability to turn improved revenue into sustained fiscal discipline and higher growth.
The latest inflation reading reflects continued price pressures: annual inflation was 4.5% in September, up from 4.4% in August, while the consumer price index rose 0.4% month on month. The data, published on October 21, the day the budget statement was presented, do not support the claim that inflation came in below documented market expectations. In markets, the South African government’s R209 bond yield fell by 14 basis points that day, from 8.865% to 8.725%. Over the medium-term fiscal horizon, the Treasury expects the deficit to decline to 2.5% of GDP by 2030, and gross tax revenue to rise from 2.14 trillion rand in 2026/27 to 2.53 trillion in 2029/30. The ministry also expects to submit a fiscal anchor bill to parliament in 2027, while a Bank of America note forecast Moody’s and S&P updates in late November and a Fitch update in December.
