The stabilisation arrives, the upgrade watch begins
Debt stopped rising at 78.4% of GDP, and interest still costs about R1.2bn a day. The MTBPS's new fiscal anchor has no number in it and no escape clause defined in advance.
R1.2 billion a day. That is what the state will spend on interest this year, as Daily Investor put it on Wednesday. Treasury's Medium Term Budget Policy Statement puts debt-service costs at R441.5 billion for 2026/27, about 21 cents of every rand of revenue. The good news in Finance Minister Enoch Godongwana's 21 October MTBPS is that the debt behind that bill has stopped growing faster than the economy.
What was tabled
For the first time in nearly two decades, gross debt stabilised: 78.4% of GDP in 2025/26, below the 78.9% the February Budget projected. Treasury now has it falling to 76.6% by 2029/30. The consolidated deficit narrows to 3.9% of GDP this year (4.0% in February) and 2.5% by 2029/30. The primary surplus, revenue minus non-interest spending, grows from 1.7% of GDP toward nearly 3% by 2030. Growth for 2026 was cut to 1.2%, from 1.6%.
The margin is mostly one-off. Gross tax revenue is R17.1 billion above the February estimate, from corporate tax, dividends tax and VAT, and Treasury says a large part comes from commodity prices that will fade. Counting royalties and money returned by public entities and the Central Energy Fund, main-budget revenue is R54.1 billion above Budget. Some goes to a contingency reserve raised to R10 billion and R20 billion for infrastructure projects still in evaluation. A further R38.1 billion in savings was found over the medium term, on top of February's R12 billion. Spending still grows 3.6% a year, from R2.72 trillion to R3.02 trillion by 2029/30.
The fuel levy falls by R3 a litre on diesel and R1.50 on petrol from 4 November, municipal election day, to 1 December, then by R1.50 and R1 until 5 January 2027. It costs R10 billion in forgone revenue, funded by returning the R10 billion sent to the Central Energy Fund to the National Revenue Fund and the contingency reserve. The speech also says the R10 billion reserve is there for El Niño. It doesn't say whether that is one R10 billion or two.
An anchor with no number
Draft fiscal-anchor legislation, out for comment and due in Parliament in 2027, writes a fiscal sustainability standard into the Public Finance Management Act instead of a debt cap. Each new Cabinet approves a fiscal plan, reports against it in every Budget and MTBPS, and explains material departures. The Financial and Fiscal Commission assesses the plan, and government and Parliament must answer its advice.
Halo or noose? set three tests for this. A principle that binds: partly, through what Treasury calls "binding duties to disclose, assess and explain." An escape clause defined in advance: no, since departures are explained after the fact. A growth path the numbers can carry: honestly shown, and less comfortable. Lower nominal growth leaves debt at 78.2% of GDP at the end of this financial year, not the 77.3% February projected. Chapter 2 of the textbook argues for a credible rule with clear escape clauses. The draft builds the accountability half and leaves the rule itself to each administration.
What to watch
Moody's and S&P both have South Africa on positive outlook, Fitch on stable (Treasury's ratings record). Their next reviews are the first verdict on the turn. The February 2027 Budget is the second, when the commodity cushion thins and the anchor bill takes shape. SA Policy Space tracks the path under fiscal consolidation and debt stabilisation.
Godongwana tabled the first MTBPS in nearly twenty years that can credibly say the debt ratio has stopped climbing. The February Budget will show whether the government is prepared to make it fall.
