Oil Just Crashed 16% in a Single Day — Here's What the Ceasefire Means for South Africa

President Trump's Tuesday deadline forced Iran to the table — and it worked. After weeks of pressure, a two-week ceasefire was announced on Tuesday evening, with Iran agreeing to reopen the Strait of Hormuz. Oil immediately crashed — Brent crude dropped from $110 to $92 in a single session, the biggest one-day fall in years. Bitcoin surged past $72,000. Global markets rallied. And South Africans, who've been absorbing the worst fuel price shock in the country's history, finally got a reason to exhale.


Three things to know:

  1. Brent crude crashed 16% in a single trading session — from $110 to $92 per barrel — after the US and Iran agreed to a two-week ceasefire and the reopening of the Strait of Hormuz. It's the biggest single-day oil price drop since the early days of the pandemic in 2020.
  2. Bitcoin hit a three-week high of $72,700, up nearly 5%, as the ceasefire triggered a global risk-on rally. Almost $600 million in leveraged crypto short positions were liquidated in hours.
  3. South Africa's temporary R3-per-litre fuel levy cut expires on 1 May. Even with oil at $92, the expiry of the levy relief means motorists will still face higher prices at the pump next month — unless the government extends it.

Thirty-eight days. That's how long the Strait of Hormuz was effectively closed.

On February 28, the US and Israel launched coordinated strikes on Iran's nuclear and missile infrastructure. Iran responded by blockading the strait — the narrow shipping channel between Iran and Oman through which roughly 21% of the world's oil passes every single day.

The consequences were immediate and brutal. Brent crude, which was trading at around $70 per barrel before the conflict, spiked to $117 by Monday. The rand weakened past R17 to the dollar. South African petrol prices increased by over R3 per litre on 1 April — and that was after the government cut the fuel levy by R3 to soften the blow. Without that intervention, the increase would have been closer to R6.

Then, on Tuesday evening, Trump's pressure campaign delivered a result. His deadline — 8pm ET, reopen the strait or face strikes on Iranian power plants and bridges — forced Tehran into a deal. Iran agreed to allow safe passage through the Hormuz Strait. The US agreed to suspend bombing for two weeks. Pakistan will host both delegations in Islamabad on Friday to negotiate a more permanent agreement.

Oil collapsed. Markets surged. And for the first time in over a month, there was genuine relief.

What This Means for Your Petrol Bill

Here's the uncomfortable truth: even with oil at $92, South Africans are not out of the woods.

Before the ceasefire, projections for May were catastrophic. The Central Energy Fund's data was tracking a petrol price increase of over R5 per litre and a diesel increase of more than R10 per litre for 1 May. Those projections were based on oil above $110 and a rand above R17.

The ceasefire changes the oil side of that equation significantly. If Brent stays around $90-95 through the rest of April, the petrol increase will be substantially smaller — possibly R1-2 per litre instead of R5.

But there's a catch. The temporary R3-per-litre fuel levy cut that the government introduced on 1 April expires on 5 May. That means even if the basic fuel price drops thanks to cheaper oil, South Africans will lose R3 per litre of levy relief at the same time.

The net effect: May fuel prices will likely be similar to — or slightly higher than — current April levels, even with oil $25 cheaper than its peak. The levy expiry eats the saving.

The DA has called for a permanent 50% fuel levy reduction. The government hasn't committed either way. If the ceasefire holds and oil stays below $100, extending the levy cut becomes a much easier fiscal decision.

What Bitcoin Did

While oil was crashing, Bitcoin was surging.

Bitcoin jumped nearly 5% to $72,700 — its highest level since 18 March — as the ceasefire triggered a broad risk-on rally across global markets. The Nikkei gained 4.5%. The Kospi jumped 5.5%. US stock futures surged.

Nearly $600 million in leveraged crypto short positions were liquidated as prices spiked, the largest short squeeze since January. Traders who had bet on further declines were wiped out in hours.

Here's the number worth remembering: when the war started on February 28, Bitcoin was trading around $85,000. It dropped to $63,000 in the panic selling that followed — a 26% drawdown. It has since recovered to $72,700. Anyone who panic-sold at $63,000 locked in a loss that the market has already recovered more than half of.

The lesson isn't that Bitcoin always goes up. It doesn't. The lesson is that selling into a geopolitical panic almost always looks wrong six weeks later. This has been true after every major crisis — COVID in March 2020, the Russia-Ukraine invasion in February 2022, and now Iran in 2026.

Is It Over?

Not yet. This is a two-week ceasefire, not a peace deal.

Oil is still at $92 — more than 30% higher than before the war started. The rand is still above R17. Iran's conditions for a permanent deal include sanctions relief, an end to Israeli operations, and reconstruction commitments. Trump wants to seize Iran's oil fields. These positions are far apart.

If the Islamabad talks on Friday collapse, the strait could close again and oil could spike back above $100 within days. Markets know this, which is why the relief rally — while significant — hasn't fully reversed the war premium.

But for now, the tankers are moving. Oil is flowing. And the immediate crisis — the one that was pushing South Africa toward the biggest fuel price increase in its history — has eased.

The next thirty days will tell us whether this pause becomes a peace, or just a breath before the next escalation.
