Why the Rand Roared: ZAR/KRW’s 5.9% Rally and the Hidden Levers of Emerging Markets

In a world where emerging-market currencies often move in the shadow of global titans, the South African rand has staged a performance worthy of the spotlight—climbing 5.9% against the Korean won in just three months. What’s behind this unexpected leap? It’s a story of gold glimmers, rate restraint, and the politics of unpredictability. Let’s pull back the curtain on the ZAR/KRW act.

Gold Fever and the New Rand Alchemy

The rand’s ascent is not an accident—it’s a high-wire act performed above a safety net woven from South Africa’s mineral riches. Gold—responsible for a shimmering 25% of the nation’s export earnings and raking in over R356 billion (7.3% of GDP)—has soared to record highs, brushing against $2,400/oz as central banks scramble to add bullion to their vaults. Platinum prices, too, jumped 36% in Q2 2025 on the back of Chinese demand and supply snags. For every uptick in these metals, South Africa’s trade balance gets a shot of adrenaline, and the rand, in turn, flexes its muscles on the global stage.

Policy Theatre: When Central Banks Make the Audience Hold Its Breath

South Africa’s Reserve Bank (SARB) has proved itself a master of suspense. Through most of 2025, the repo rate stood at a punchy 7.5%, keeping bond yields attractive for global investors hunting for returns as the US Fed chopped its own rates to 4.00–4.25%. The SARB’s cautious July trim to 7.25% was more of a nudge than a dive, signaling to markets that inflation—last seen at a tame 3.3% in August—remains under control. This ‘yield magnet’ effect has lured capital into rand-denominated assets, providing a sturdy tailwind for the currency.

Contrast this with Korea’s more sedate monetary stance, where policy rates have hovered in a narrow band and inflation has posed less of a challenge. The result? The rand’s relative allure has only grown stronger for carry traders and institutional investors alike.

Trade Surpluses and the Invisible Handshake

Behind every strong currency stands a trade account with a spring in its step. May and June delivered surpluses of R21.67 billion and R22 billion respectively, narrowing the current-account deficit to just 0.5% of GDP at one point. With exports riding high and oil imports kept in check by lower global prices, there’s been an almost mechanical demand for rand: foreign buyers must swap their won (and other currencies) for ZAR to pay for South African goods.

This isn’t just a numbers game. It’s a confidence game. Each surplus is a handshake between South Africa and the world—one that says, “We’re open for business, and our books are in order.” The rand responds accordingly, and nowhere is that more evident than in the last three months’ chart.

Geopolitical Knives and the Art of Dodging

Of course, no rally comes without its share of tension. The rand has had to dodge a barrage of political uncertainty—debates over nationalising the central bank, threats of US tariffs (30% on select South African goods), and the never-ending spectre of coalition politics. Yet, the rand’s resilience has been remarkable. Even after the US imposed tariffs on 2 April 2025, the ZAR managed to absorb the shock, partly because key exports like gold and PGMs escaped the tariff net. Meanwhile, Korea’s won has felt the chill of global trade volatility and weaker regional demand, adding to the ZAR/KRW spread.

Not All That Glitters: The Risks Lurking in the Orchestra Pit

For all the recent bravado, the rand is no stranger to sharp reversals. Political rifts, load-shedding, and social unrest remain ever-present risks. But over the last three months, the market’s focus has been on South Africa’s ability to deliver hard currency and tight fiscal signals—even as the script for 2026 is still being written.

The Final Bow: What the Charts Refuse to Say Aloud

With ZAR/KRW up 5.9% in a single quarter, the rally isn’t just a number—it’s the sum of gold’s luster, SARB’s choreography, surplus-driven confidence, and a dash of global risk-on mood. For the moment, the rand has outperformed its EM peers, not because it is flawless, but because it is—right now—just a little less flawed, and a lot more interesting.

In the world of currencies, that’s enough to steal the show—at least until the next act.
