Goldman Sees South Africa Tax Revenue Surge Triggering Rating Upgrades

Goldman Sachs sees South Africa positioned for further credit upgrades

South Africa’s corporate tax collections for June reached R385-billion on a semi-annualised basis, a figure that Goldman Sachs Group Inc. says positions the country for additional credit-rating upgrades within the next twelve months.

The National Treasury released the data this week. That R385-billion represents growth of approximately 5.5%, substantially exceeding both the R345-billion collected in the prior 2025-26 fiscal year and the R364-billion the February budget had projected for 2026-27. Mining-industry export profits drove much of the outperformance.

Andrew Matheny, an economist at Goldman Sachs, drew a direct line from the revenue figures to sovereign credit standing. “From a sovereign credit rating perspective, the continued strength in these fiscal data reinforce our expectation that both Moody’s and S&P will upgrade their credit ratings over the next year,” Matheny wrote in a research note.

Both agencies have already moved. Moody’s Ratings, which holds South Africa at Ba2, kept that rating unchanged in May but shifted its outlook from stable to positive, citing an improved fiscal position, the authorities’ demonstrated commitment to stabilising state finances, and progress on economic reforms. S&P Global Ratings moved more decisively in November, delivering the country’s first upgrade in two decades, for the same underlying reasons: fiscal improvement, government commitment to consolidation, and reform implementation.

A further S&P upgrade would lift South Africa’s rating to BB+ from its current BB level. Matheny flagged a specific market implication: “current pricing does not reflect expectations for a credit rating upgrade,” suggesting that fixed-income instruments may be mispriced relative to the likely trajectory of the country’s credit standing.

The broader fiscal picture supports that view. South Africa, the continent’s largest economy, recorded a primary budget surplus of 1.1% of gross domestic product in the year through March, ahead of the National Treasury’s February forecast of 0.9%. That outperformance reflects consolidation efforts that have built confidence among rating agencies and market participants alike.

What makes the revenue story particularly compelling for investors is its composition. The outperformance is not the product of spending cuts or one-time items. It reflects genuine economic strength in key revenue-generating sectors, with mining leading the way. That distinction matters to rating analysts assessing the durability of fiscal improvement.

For holders of South African fixed-income assets, the mechanics of an upgrade are straightforward: lower borrowing costs, a broader investor base willing to hold the country’s debt, and potentially tighter yields. The question now is whether market pricing will adjust before the agencies act, or after.
