Rand Rallies on Iran Deal Hopes as Fitch Upgrades SA and an AI Selloff Rattles Global Markets
The rand finished the week firmly on the front foot — strengthening from around 16.57 to 16.29 against the dollar — as hopes of a US-Iran deal sparked a risk-on rally that overshadowed a brutal global tech selloff, a long-awaited Fitch ratings upgrade, and a string of weak domestic data. Here's our weekly wrap of what moved the market.
Global markets: the AI rally unwinds
The week opened with a sharp risk-off shock as the AI trade suffered a significant momentum unwind. Broadcom's disappointing AI revenue guidance missed lofty expectations on custom-chip demand and raised fresh doubts over near-term growth in the semiconductor supply chain. The fallout was severe: the Nasdaq fell 4.2% in its worst session in months, with Nvidia down around 6% and Broadcom nearly 8%, as tech megacaps shed over $1 trillion in market value in a pronounced rotation out of growth names and into defensives. Asian markets extended the rout, with South Korea's KOSPI plunging 5% and Japan's Nikkei dropping 3.8%. By Friday, however, sentiment had flipped decisively. President Trump signalled that a deal to end the Iran conflict could be signed as soon as the weekend, sparking a powerful rally in US equities, a broad improvement in risk appetite, and a welcome slide in oil prices back towards pre-war levels.
Fitch upgrade: a milestone two decades in the making
In a landmark move, Fitch Ratings upgraded South Africa's long-term foreign- and local-currency sovereign ratings by one notch to BB from BB-, retaining a stable outlook. It marks the country's first Fitch upgrade in almost 21 years and reflects a material improvement in sovereign credit fundamentals after a prolonged downgrade cycle. South Africa is now aligned at broadly comparable speculative-grade levels across the major agencies. For fixed-income investors, the decision reinforces the perception that fiscal-slippage risks have moderated. That said, the sovereign remains two notches below investment grade and is still exposed to weak trend growth, policy-execution risks and external shocks — which is partly why the rand initially looked through the news, weakening early in the week in line with broader emerging-market risk aversion.
Domestic data: soft GDP and a manufacturing slump
The local data pulse was underwhelming beneath the surface. Q1 GDP looked superficially encouraging, with seasonally adjusted growth of 0.5% q/q (above Q4's 0.4%) and annual growth improving to 1.9% from 0.8%. But the composition was less reassuring: the lift came largely from a sharp fall in imports — partly linked to weaker oil inflows after Straits of Hormuz disruption — and a rebound in agriculture, rather than from healthier capital formation. The picture darkened on Friday, when manufacturing production contracted 2.9% y/y in April, badly undershooting expectations of a 1.5% expansion and reversing March's 1.5% growth. Weakness was broad-based: vehicle manufacturing swung to an 11% contraction, basic iron and steel fell 6%, and food growth slowed to 1.5%. Elevated operating costs, infrastructure constraints and subdued domestic demand continue to weigh on the industrial sector.
Bonds: liquidity pressure and a cautious SARB
South African bonds spent much of the week under pressure, driven largely by tighter global liquidity conditions. Unusually, the equity selloff did not trigger the customary rotation into safe-haven bonds — global bond markets sold off alongside stocks, as central banks diversified away from US assets and fund managers made room for a wave of massive IPOs that threaten to drain investible liquidity. The midweek vanilla SAGB auction reflected this caution, with total bids easing to R9.345 billion from the prior week's exceptional R16.945 billion, though a bid-to-cover ratio of 3.7x showed appetite for SA debt remains reasonably intact. On policy, the SARB's Financial Stability Review framed the Middle East shock less as a transient oil-price disturbance and more as a balance-sheet stress test — tighter financial conditions, weaker growth, higher inflation, capital outflows and fiscal fragility reinforcing one another — an assessment that argues for a clear tightening bias. By Friday, sharply lower US Treasury yields and the prospect of an Iran deal set the stage for a domestic bond recovery.
USD-ZAR: the week in numbers
The pair began the week around 16.5650, with the rand looking through the Fitch upgrade and weakening alongside high-beta emerging-market peers amid the global tech rout; the rand also lost ground on the crosses, with EUR-ZAR near 19.10 and GBP-ZAR around 22.09. It then settled into a weaker three-day range between support at 16.3800 and resistance at 16.7800, even forming a bull flag that threatened a topside break. That structure was decisively broken on Friday when the prospect of an Iran deal, softer oil and a weaker dollar drove the pair down to around 16.2900 — its best level of the week. Support now sits at the key 16.2000 area, with resistance towards 16.5000. A sustained break below 16.2000 would invite further rand gains, though oil prices, the path of Middle East diplomacy and import demand remain the decisive catalysts. Volatility, as ever, remains the order of the day.
