Inflation was 3.5% in January.Traders have already lowered bets in derivatives markets for a SARB rate cut later this year and have begun to price in a potential hike.Still, Matheny said the conflict is unlikely to significantly derail South Africa’s improved fiscal outlook, unless the economy deteriorates sharply.Finance Minister Enoch Godongwana’s budget last month showed government debt as a percentage of gross domestic product peaking in the fiscal year through March and then gradually falling, with GDP growing 1.6% in 2026 and rising to 2% in 2028.Revenue projections by the National Treasury are “extremely conservative,” Matheny said. Collections may exceed budget forecasts by as much as 20 billion rand ($1.2 billion) in the current fiscal year, he said.Higher commodity prices also present upside risks to revenue because they’re largely not incorporated into the government’s assumptions for 2026, Matheny said..© 2026 Bloomberg L.P.
