South Africa’s National Treasury will likely make a “heroic effort” to defend its fiscal targets despite a sharp deterioration in the country’s economic circumstances, demonstrating once again why its institutional conservatism and pragmatism have been among the country’s most valuable economic assets.

An assessment by advisory firm Frans Cronje Private Clients ahead of the Medium-Term Budget Policy Statement (MTBPS) on 21 October suggests that the Treasury may pursue what the firm calls a “heroic effort” to protect its debt and deficit projections, even as the economic assumptions underpinning February’s budget have fallen away.

The scale of the challenge is considerable.

The Treasury’s February budget anticipated economic growth of 1.6% in 2026. Growth is now more likely to reach between just 1.1% and 1.2%, according to the firm’s assessment. Inflation, initially forecast at 3.4%, could reach between 4.5% and 5.0%, while the average Brent crude oil price for the year could approach $95 against the $62 assumed by market analysts in February.

Business and consumer confidence have also both declined significantly since the first quarter of 2026.

These circumstances create significant pressure on the Treasury’s February projections of a budget deficit of 4.0% of GDP and government debt peaking at 77.3% of GDP in 2026 before declining to 77.0% in 2027 and 76.5% in 2028.

Yet the firm’s assessment is that the Treasury remains fiercely determined to hold the line.

This matters because the Treasury’s conservatism and pragmatism have long served as an important countervailing force against South Africa’s wider economic and policy failures. Its institutional commitment to fiscal credibility has helped prevent the country’s economic circumstances from deteriorating more severely than they otherwise might have.

Had reckless fiscal policy been run against South Africa’s hostile investment climate, the consequences would have been severe for all South Africans. Rising government debt and widening deficits would undermine investor confidence, increase the cost of borrowing, weaken the rand, and put upward pressure on inflation and interest rates. As debt servicing costs rose, an ever-greater share of tax revenue would be diverted away from infrastructure, policing, education, and other essential services simply to pay interest on past borrowing. Private investment would be crowded out, economic growth would weaken further, and the government would face the prospect of punishing tax increases, deep spending cuts, or a full-blown fiscal crisis. South Africa’s already fragile economic circumstances would become considerably worse, and reversing the damage could take many years.

The Treasury’s pragmatism is too often taken for granted. Much of what has gone wrong in South Africa's economy is plainly visible, from failing infrastructure to weak growth and high unemployment. What is less visible, and consequently less appreciated, is the extent to which sound fiscal management has helped contain the damage. The Treasury’s record deserves considerably more recognition than it generally receives.

If the Treasury delivers credible numbers next week despite the substantially worse economic environment, it will provide another demonstration of the value of that institutional discipline and should be well received by financial markets.
