Budget optimism lifts rand as bond yields soften

The South African rand’s early-week rise to ZAR 17.2550 per US dollar (a 0.3% firming) is a direct reflection of improving market sentiment ahead of two critical events: the imminent release of the mid-year budget review by National Treasury and growing speculation that the country may finally secure a sovereign credit-rating upgrade from S&P Global Ratings.

The still fragile fiscal position of Africa’s most industrialized economy is characterized by a budget deficit targeted at ~4.8% of GDP in the current fiscal year (FY2024/25). Economists are projecting a narrower 4.4% deficit for FY2025, which, given nominal GDP of approximately US$410 billion and government debt above 70% of GDP, carries material implications for bond yields, currency stability, and the overall cost of external funding.

The mechanism driving the firmer rand revolves entirely around risk sentiment: markets are pricing in lower funding risk and potential portfolio inflows in anticipation of a favorable ratings review.

The upcoming budget review is crucial as it shapes expectations on economic growth forecasts (projected at a low ~1.0–1.5% real for 2025), inflation targeting (Treasury is under pressure to lower the target range from 3–6% to around 3%), and credible debt-service trajectories.

With inflation hovering at ~5.6% in September year-on-year and the benchmark 2035 government bond yield at 8.815% at the start of the week, a credible articulation of fiscal consolidation could tighten sovereign spreads, significantly reduce long-term funding costs, and further support the ZAR.

Sector implications of this improved sentiment include cheaper dollar funding for local corporates and potential cost relief for major commodity exporters, whose imported input costs will be lower with a stronger currency. In equity markets, the JSE Top 40 index is testing a breakout toward ~103,950 ZAR, underpinned by improved fiscal expectations.

However, meaningful forward risks persist. If the budget review fails to deliver convincing structural reforms, growth could slip below the projected rate, unemployment—already high at ~32.9% in Q2—will remain stubbornly high, and energy constraints (load-shedding) could continue to weigh on productivity. A credit ratings downgrade, conversely, would reverse sentiment sharply: the rand could weaken beyond ZAR 18/USD, bond yields widen by 40–60 basis points, and foreign capital exit could accelerate.

Looking into the first half of 2026, market participants should focus intently on the sovereign bond spread versus the US 10-year Treasury yield (currently ~450 bps, calculated as 8.8% minus 4.3%).

A narrowing of this spread below ~400 bps would signal sustained investor confidence; a widening above ~500 bps would represent a significant deterioration in risk perception.

Currency watchers should monitor quarterly current-account balances and ETF flows: sustained inflows of >~US$500 million per quarter into local fixed income or domestic equity would provide structural support for the ZAR.
