2026 MEDIUM-TERM BUDGET POLICY STATEMENT

What analysts and the bond market will be watching

Pre-MTBPS briefing  |  Prepared 16 October 2026  |  MTBPS to be tabled 21 October 2026

Context

Finance Minister Enoch Godongwana will table the 2026 Medium-Term Budget Policy Statement (MTBPS) in Parliament on 21 October 2026. The MTBPS does not normally contain tax changes; instead, it revises the economic outlook and fiscal framework and sets the direction for the February 2027 Budget.

It arrives at an unusual moment. On the positive side, debt stabilised in 2025/26, South Africa has received rating upgrades from S&P (November 2025) and Fitch (June 2026), and high precious-metal prices have lifted tax collections. On the negative side, the Middle East conflict has driven fuel prices to record levels, GDP contracted in the second quarter, the Reserve Bank has raised the repo rate to 7.25%, and the 10-year government bond yield has risen to around 9% from below 8% earlier in the year. Local government elections follow on 4 November, and Moody’s and S&P review the sovereign on 27 November. Going into the statement, the benchmark 2035 bond was trading near 8.69% and the rand around R16.45 to the dollar (Reuters, 16 October).

This briefing draws on a broad range of views: bank and asset-manager economists (Bank of America, Goldman Sachs, Investec, Momentum, Stanlib, PSG, ETM Analytics), the South African Institute of Taxation, international institutions (IMF, World Bank, IIF, S&P, Fitch), the SARB and National Treasury, and financial media reporting.

 

Part A: Five most important items analysts will watch

Table 1 summarises the five items most frequently highlighted in economists’ previews of the 2026 MTBPS.

Table 1. Key MTBPS items

# Item What analysts will be looking for Analyst views and reference numbers
1 Revenue revision and how the windfall is used The size of the upward revision to 2026/27 tax revenue, how much Treasury treats as permanent rather than commodity-driven, and whether the extra money reduces borrowing or is absorbed by spending. Feb 2026 main-budget revenue: R2,082bn.Bank of America: revenue could beat the Budget by ~R70bn; corporate tax up 22.8% y/y on gold and PGM miners.Investec: revenue at 39% of budget after 5 months, ahead of last year but below a pro-rata R868bn.PSG: overrun of R50bn or more.
2 Expenditure pressures and new allocations Whether the R2,383bn expenditure ceiling holds, and the size of in-year top-ups: fuel-levy relief, the SRD grant court case, municipal-election costs, the wage bill and SOE/municipal support. Bank of America: spending growing 4.6% vs 2.5% assumed; could exceed baseline by ~R53bn, leaving a net gain of only ~R20bn.Investec: spending R1,001bn after 5 months vs pro-rata R993bn.Fuel-levy relief (Apr–Jun): R17.2bn forgone (Treasury).SRD grant ruling: up to R93.5bn a year extra (Treasury); appeal before the SCA.
3 Budget deficit and primary surplus The revised 2026/27 deficit and whether the primary surplus path is kept on track, given the gap between strong revenue and faster spending. Feb target: ~3.7–4.0% of GDP (analysts cite different measures).Bank of America: 3.5% (≈R283bn), possibly nearer 3% if spending is contained.Investec: 4.0%, risk of ~4.1%; deficit after 5 months R189bn vs pro-rata R125bn.SAIT: expects a wider deficit.Treasury primary surplus path: 1.6% (2026/27) to 2.3% (2028/29).
4 Fiscal anchor proposal Design of the promised principles-led fiscal anchor: the compliance metric, any triggers or escape clauses, the legislative timetable and an independent oversight body. Treasury: proposal to be tabled in this MTBPS; each new administration to table a sustainability plan.IMF: recommends 70%-of-GDP interim debt target (early 2030s), 60% long term.Business Day commentary: warns principles without triggers lack bite.Investec: markets want flexible but significant limits on spending and borrowing.
5 Revised growth and inflation outlook How far Treasury cuts its growth forecast after the oil shock and Q2 contraction, and the inflation and interest-rate assumptions that drive nominal GDP, revenue and interest costs. Feb Budget: 1.6% growth for 2026.SARB 1.2%; S&P 1.3%; IIF 1.3%; World Bank 1.0%; SAIT: below 1%.Q2 2026 GDP: -0.2% q/q (Stats SA).Repo 7.25% (23 Sep); Stanlib expects CPI to exceed 5% after fuel hikes (target 3%).

Significance of the five MTBPS items

1. Revenue revision and how the windfall is used

Revenue is the swing factor in this MTBPS, and analysts broadly agree that it is running ahead of plan because of the gold and platinum price rally. Bank of America estimates the overrun could reach about R70 billion, driven chiefly by corporate tax from precious-metal producers, while personal income tax and VAT are roughly on budget. PSG puts the figure at R50 billion or more. Investec is more measured: revenue is ahead of last year’s pace but still below a simple pro-rata share of the annual target, and monthly collections are uneven.

The significance lies less in the size of the windfall than in its use. Commodity-driven revenue is cyclical, so analysts expect Treasury to carry only part of it into future years. If the extra money cuts borrowing, it strengthens the debt path and supports bonds. If it funds permanent spending, markets will see a repeat of 2025, when Investec notes most of the overrun was absorbed by new allocations.

2. Expenditure pressures and new allocations

Bank of America’s analysis captures the central tension: spending is growing about 4.6% against the 2.5% assumed in February and could exceed the baseline by roughly R53 billion, leaving a net fiscal gain of only around R20 billion despite the revenue windfall. Investec’s data show spending already slightly above the pro-rata share of budget after five months. Specific pressures include fuel-levy relief worth R17.2 billion in forgone revenue, the 4 November local government elections, the public-service wage bill and support for SOEs and municipalities.

The largest medium-term risk is the Social Relief of Distress (SRD) grant. A High Court ruling would widen eligibility, which Treasury estimates could cost an extra R93.5 billion a year; government has taken the matter to the Supreme Court of Appeal, and Bank of America calls it the main medium-term fiscal uncertainty. Analysts will look for how Treasury provisions for this risk and whether the expenditure ceiling is held, because the GNU has little appetite for tax increases and unfunded spending must be borrowed.

3. Budget deficit and primary surplus

Analysts quote the February target for 2026/27 at between 3.7% and 4.0% of GDP, depending on the measure used. Forecasts diverge: Bank of America expects about 3.5% and sees room for an outcome closer to 3% if spending is contained, though it regards that as optimistic. Investec forecasts 4.0% with a risk of drift towards 4.1%, pointing out that the deficit after five months is well above a pro-rata share. SAIT expects a wider deficit as higher interest rates and a weaker rand bite.

The primary surplus (revenue minus non-interest spending) is the clearest gauge of fiscal effort, because it excludes interest costs that Treasury does not directly control. Treasury plans for it to widen steadily to 2.3% of GDP by 2028/29. Rating agencies, notably Fitch in its June upgrade, have highlighted the move to consistent primary surpluses, so any narrowing of this path would be read as slippage.

4. Fiscal anchor proposal

In the 2026 Budget, Treasury committed to tabling a principles-led fiscal anchor in this MTBPS rather than a hard numerical rule. Each new administration would have to table a medium-term plan showing that public finances remain sustainable, and Treasury officials have suggested an oversight council to hold government to account. The IMF has pushed for clearer numbers, recommending an interim debt target of 70% of GDP by the early 2030s and 60% over the longer term, while Business Day commentary warns that principles without published triggers amount to accountability by announcement.

This is the most important structural announcement in the MTBPS. Markets want to know which metric will measure compliance, whether there are triggers and correction mechanisms, and when the framework will become law. Investec notes markets are looking for flexible but meaningful limits on spending and borrowing. A credible anchor would lower the risk premium on government bonds and support further upgrades; a vague one would disappoint.

5. Revised growth and inflation outlook

The macro backdrop has deteriorated since February. The Middle East conflict pushed fuel prices to record highs, GDP contracted by 0.2% quarter-on-quarter in Q2, and forecasters have cut 2026 growth well below Treasury’s 1.6%: the SARB to 1.2%, S&P and the IIF to 1.3%, and the World Bank to 1.0%, while SAIT expects growth below 1%. Inflation is rising again: the SARB has lifted the repo rate twice this year to 7.25%, and Stanlib’s Kevin Lings expects CPI to exceed 5% once recent fuel increases feed through, far above the new 3% target.

These assumptions flow straight into the fiscal numbers. Lower nominal GDP raises the debt ratio for any given level of borrowing and weighs on future revenue, while higher rates lift interest costs. Analysts will test whether Treasury’s revised macro forecasts are realistic, since over-optimism would undermine the credibility of the whole framework. SAIT’s Keith Engel has described this MTBPS as a test of resilience.

Part B: Five most important debt indicators for the bond market

Table 2 sets out the debt indicators in the MTBPS that are most likely to move South African government bond (SAGB) yields, the yield curve and the rand.

Table 2. Debt indicators that will impact the SA bond market

# Debt indicator Why the bond market watches it Latest official / analyst position
1 Gross debt-to-GDP ratio and its trajectory Confirms whether debt really peaked in 2025/26 and is now falling. Any upward revision would undermine the stabilisation story behind recent upgrades. Treasury: peak 78.9% (2025/26); 77.3% (2026/27); 76.5% (2028/29).Bank of America: expects ~77% this year.Investec: a ratio above 77.3% would push yields higher.SAIT: higher rates and weaker rand challenge the 77.3% target.
2 Debt-service costs (interest bill) Measures how much revenue is consumed by interest. Highly sensitive to bond yields, inflation (via inflation-linked bonds) and the rand (via foreign debt). Treasury: R432.4bn for 2026/27 (reply to Parliament).Roughly a fifth of revenue, vs under 9% before 2008.Bank of America: interest costs up only 0.5% y/y in first 5 months, the flattest in over a decade.
3 Gross borrowing requirement and bond issuance Sets bond supply: weekly auction sizes, nominal vs inflation-linked mix, switches and foreign-currency issuance. Lower supply supports prices and can flatten the curve. 2025/26: R563.4bn incl. R80bn Eskom debt relief (~R1.5bn a day).Business Day: Budget Review saw ~R380bn in 2026/27, helped by R56bn of GFECRA transfers.Bank of America: ~60% of 2026/27 financing secured after 5 months; external programme effectively complete.
4 Sovereign credit ratings and outlooks The MTBPS is the last fiscal update before the Moody’s and S&P reviews. Upgrades lower the risk premium and widen the investor base. S&P BB/BB+ positive; Moody’s Ba2 positive; Fitch BB stable (upgraded Jun 2026).Momentum: Moody’s and S&P reviews on 27 Nov 2026.Bank of America: Moody’s most likely to upgrade (Ba1); S&P a closer call.Goldman Sachs: investment grade by 2028; local yields could fall to ~7.6%.
5 Contingent liabilities (SOEs, guarantees, municipalities) Bailouts or called guarantees for state companies, and municipal distress, can move onto the sovereign balance sheet and raise borrowing needs without warning. Treasury Budget Review: SOE pressures could raise funding costs.Eskom debt relief (R80bn in 2025/26) still in the borrowing numbers.Bank of America: unstable metro coalitions after 4 Nov elections could strain the GNU.

Significance of the five debt indicators

1. Gross debt-to-GDP ratio and its trajectory

The 2026 Budget declared that debt stabilised in 2025/26 at 78.9% of GDP, the first stabilisation in 17 years, with a projected decline to 77.3% in 2026/27 and 76.5% by 2028/29. Bank of America expects the ratio to fall to about 77% this year, consistent with the plan, whereas SAIT warns that higher interest rates and a weaker rand could challenge the 77.3% target.

Investec stresses that any rise above 77.3% would push South African bond yields higher and that significant deviations from the medium-term path would be badly received. The peak itself was revised up between the 2025 MTBPS and the 2026 Budget, so the market is sensitive to another upward revision, particularly if slower nominal growth mechanically raises the ratio.

2. Debt-service costs

Treasury estimates interest costs for 2026/27 at R432.4 billion, meaning roughly one rand in five of revenue goes to servicing debt. Encouragingly, Bank of America notes that debt-service costs rose only 0.5% year-on-year in the first five months, the flattest outcome in over a decade, helped by lower yields earlier in the year and a stronger rand.

This indicator is the channel through which the bond market feeds back into the budget. Higher yields, higher inflation (which raises the cost of inflation-linked bonds) or a weaker rand (which raises the rand value of foreign debt) all increase the bill. With the repo rate up 50 basis points this year and yields higher than in the first quarter, analysts will check whether Treasury still projects interest costs growing more slowly than total spending.

3. Gross borrowing requirement and bond issuance

The gross borrowing requirement combines the deficit with maturing debt and other financing needs. For 2025/26 it was R563.4 billion including R80 billion for Eskom debt relief, about R1.5 billion a day. Business Day reported that the Budget Review expects it to fall to about R380 billion in 2026/27, helped by GFECRA transfers. Bank of America estimates that about 60% of the 2026/27 requirement had been funded after five months and that the external (foreign-currency) programme is effectively complete.

For bond investors this is a direct supply signal. If revenue gains reduce the requirement, Treasury can trim weekly auctions or lean more on Treasury bills, supporting bond prices and flattening the curve. If it rises, expect larger auctions, more long-dated issuance and upward pressure on yields. The nominal versus inflation-linked mix and switch auctions to smooth redemptions will also be watched.

4. Sovereign credit ratings and outlooks

All three major agencies rate South Africa two notches below investment grade: S&P upgraded in November 2025 and has a positive outlook, Moody’s has a positive outlook, and Fitch upgraded to BB in June 2026, its first upgrade in almost 21 years. Momentum points out that Moody’s and S&P review South Africa on 27 November, five weeks after the MTBPS. Bank of America sees Moody’s as most likely to act, with a possible upgrade to Ba1, and regards an S&P move as a closer call.

Goldman Sachs argues that markets are not yet fully pricing a return to investment grade, which it projects by 2028, and sees local-currency yields falling to around 7.6% on that path. Market pricing ahead of the statement reflects this optimism: Reuters reported investors expecting an improving budget balance and a better ratings outlook, with the benchmark 2035 bond near 8.69% on 16 October, while ETM Analytics expects the statement to keep traders cautious. A disciplined MTBPS would strengthen the upgrade case; slippage would delay it.

5. Contingent liabilities (SOEs, guarantees and municipalities)

Contingent liabilities are debts the state may have to absorb even though they sit outside the main budget: guarantees to state companies such as Eskom and Transnet, liabilities of entities such as the Road Accident Fund, and the deepening distress of municipalities. Treasury’s own Budget Review warns that pressures in state-owned companies could raise government funding costs.

For the bond market these are the main source of surprise risk, because a new bail-out or called guarantee adds directly to the borrowing requirement. Bank of America also flags that the 4 November local government elections could entrench fragmented, unstable metro coalitions that strain the GNU. Investors will look for disclosure of any new support for SOEs or municipalities and how it would be funded.

Bottom line

The 2026 MTBPS is a credibility test. The market’s central question is whether Treasury converts a partly cyclical revenue windfall into lower borrowing and a firmer debt path, backed by an enforceable fiscal anchor, despite weaker growth, higher interest rates and election-year spending pressure. A disciplined outcome would support lower bond yields and further rating upgrades from Moody’s and S&P in late November; visible slippage in the deficit, debt ratio or borrowing requirement would push yields higher and delay the return to investment grade.
