Ever wondered why the South African rand (ZAR) sometimes takes a nosedive against the US dollar (USD) overnight, or why it occasionally rallies out of nowhere even when local news is calm? If you've tracked ZAR/USD during global events—like sanctions on Russia, the Greek debt crisis, or, most recently, the COVID-19 pandemic—you've seen just how dramatically international developments can shift currency values. In this article, I’ll unpack how international sanctions and global crises hit the ZAR/USD exchange rate, peppered with my own trading experiences, hard data, and a few regulatory tidbits you won’t find in the standard textbooks.
First, let's get one thing straight: the rand isn’t just a mirror of South Africa’s economy. It’s also a proxy for emerging market risk. When big global events hit, international investors often react by moving money quickly—sometimes in and out of South Africa, but often just out of anything “riskier” than the US dollar.
I learned this the hard way in March 2020. The early days of COVID-19 were chaos. I remember watching the ZAR/USD chart on TradingView—one moment the rand was at 14.9, and within weeks it had spiked to nearly 19 against the dollar. It wasn’t just about South African lockdowns; it was that everyone, everywhere, was dumping emerging market currencies for US dollars, the global safe haven.
But why does this happen? Let’s break it down:
Let me give you a concrete timeline. In mid-February 2020, as COVID-19 cases spiked globally, South Africa’s rand hovered around 15 to the dollar. But by April, after lockdowns and a global scramble for dollars, the rand crashed to almost 19.5 ZAR per USD (Federal Reserve Economic Data).
I was working on a cross-border treasury project at the time, and our company’s hedging costs exploded. Forward rates moved against us, and importers were suddenly looking at 25% higher costs in local terms. This wasn’t just theoretical—every South African business with dollar liabilities felt the pain.
The South African Reserve Bank (SARB) intervened, but their firepower is limited compared to the Federal Reserve. The story was similar for other emerging markets, but the ZAR is more liquid than most, so it often moves further, faster.
It’s not just about the market’s mood. International finance is governed by a maze of rules. During sanctions or crises, organizations like the World Trade Organization (WTO) or OECD may weigh in on trade restrictions, which can disrupt payment flows and currency conversions. In 2014, for instance, the US Treasury’s Office of Foreign Assets Control (OFAC) imposed sanctions on Russian banks—instantly, the ruble crashed, and the euro and even the rand saw ripple effects.
South Africa’s own Exchange Control Regulations (administered by SARB) become especially important under stress. If global conditions worsen, SARB can tighten controls, making it harder for locals to take money out or for foreigners to repatriate profits. This can sometimes stabilize the rand in the very short term, but it also risks scaring off foreign investment in the long run.
Here’s my practical approach—messy, but real:
I’ve also made mistakes—more than once, I assumed a local political event would move the rand, only to be blindsided by an unrelated global crisis that sent it in the opposite direction. After the 2022 Russian invasion of Ukraine, for example, the ZAR initially strengthened with rising commodity prices, but as global risk aversion set in, it reversed sharply.

I once interviewed a currency strategist at a top South African bank (who asked not to be named). He put it bluntly: “The ZAR is the first to be sold and last to be bought when global fear spikes. It’s not always about South Africa. Sometimes, we’re just collateral damage in a world that wants dollars.”
A classic case was in 2018, when US sanctions hit Turkish assets hard. Even though South Africa had no direct stake, the rand weakened alongside the Turkish lira and Argentine peso—just because investors lumped them all as “emerging market risk.” That’s why, as a trader or treasury manager, you need both a global and local lens.
Dealing with ZAR/USD swings is, honestly, like surfing in a storm. You can’t control the waves, but you can read the weather and pick your moments. I’ve hedged invoices, scrambled to renegotiate contracts, and even had to explain to clients why their payments got stuck due to sudden capital controls. I’ve also learned to keep a close eye on both the IMF’s global outlook and SARB’s regulatory notices.
If you’re in finance, especially in cross-border roles, I recommend always having a worst-case scenario ready—because international sanctions or a new global crisis can turn a predictable market into the Wild West, fast.
To sum up, the ZAR/USD exchange rate is extraordinarily sensitive to international sanctions and global crises. It’s not just about economics or politics in South Africa—what happens in Washington, Moscow, or Beijing can matter just as much. The COVID-19 pandemic was a textbook example, but even before that, sanctions and global risk-off events repeatedly jolted the rand.
My advice? Stay plugged into both local and global news, watch for regulatory changes (especially from SARB and OFAC), and be ready to act quickly when the unexpected hits. And don’t beat yourself up if you get caught out—sometimes, even the pros are blindsided.

Next time you see ZAR/USD swing wildly, remember—it’s probably not just about what’s happening in Johannesburg. Sometimes, it’s the world’s trouble that’s coming home to roost.
