Oil surges as US-Iran clashes threaten fragile ceasefire and Strait of Hormuz access

A peace that is actively breaking apart
President Trump declared the ceasefire still in effect even as U.S. and Iranian forces exchanged fire over the Strait of Hormuz.

So the ceasefire is supposedly still in effect, but they're shooting at each other. How does that work?

Mimi

It's a ceasefire in name. Both sides are accusing the other of violations, and the U.S. says it was responding to Iranian fire. Trump says it's still technically in effect, but the reality on the water is different from the statement in Washington.

Luke

Right, but we should be careful here. We have Iran's account of what was hit, and we have the U.S. account. Those don't necessarily match. What we know for certain is that shots were fired and oil prices moved.

Mark

And the Strait of Hormuz—that's the real pressure point here, right? One-fifth of global oil supply?

Mimi

Exactly. It's been mostly shut since late February. Any hope of reopening it was what had prices falling earlier this week. Now that hope is fading.

Luke

Though we should note the peace proposal on the table doesn't actually address the nuclear issue or some other major sticking points. It's a narrow deal about the strait and the fighting, not a comprehensive settlement.

Mark

So even if they agree, there's still a lot unresolved.

Mimi

Yes. And now there's also this investigation into $7 billion in trades before Trump's announcements.

Luke

That's the CFTC looking at short positions placed before Trump said he'd delay strikes or announce the ceasefire. People betting prices would fall, and then prices did fall. Whether that's insider trading or just smart positioning based on public signals—that's what they're trying to figure out.

Mark

So someone may have known what Trump was about to say.

Luke

Or they read the tea leaves very well. The investigation will tell us which.

  • A month-long ceasefire that had briefly calmed global energy markets shattered Friday as US and Iranian forces exchanged fire in and around the Strait of Hormuz, each side accusing the other of striking first.
  • Brent crude surged past $101 a barrel and WTI climbed to nearly $96, erasing three days of price declines that had been built on now-vanished optimism about a peace deal.
  • The strait — a narrow chokepoint carrying one-fifth of global oil and gas — has been largely closed since late February, and every new skirmish tightens the world's energy supply further.
  • President Trump declared the ceasefire technically intact even as missiles flew, leaving markets suspended in a disorienting limbo between war and negotiation.
  • The CFTC has opened an investigation into $7 billion in oil trades — predominantly short positions — placed just before Trump's key public announcements, raising serious questions about whether advance knowledge of presidential statements was used to profit from the resulting price swings.

Along one of the world's most consequential waterways, the fragile hope of peace has once again given way to the logic of conflict. Fresh fighting between the United States and Iran on Friday sent oil prices sharply higher, as markets absorbed the possibility that the Strait of Hormuz — through which a fifth of the world's energy supply must pass — may remain closed far longer than anyone had dared to fear. In the background, a federal investigation into $7 billion in suspicious trades raises the older and darker question of who, in moments of public crisis, is quietly profiting from the chaos.

Oil markets surged on Friday as renewed fighting between the United States and Iran threatened to collapse a ceasefire that had, for a brief moment, offered the world a path back to stable energy flows. Brent crude climbed to $101.47 a barrel and West Texas Intermediate rose to $95.93, each gaining roughly 1.2 percent — reversing three days of declines that had followed cautious optimism about a peace agreement.

At the center of the crisis is the Strait of Hormuz, the narrow passage between Iran and Oman through which approximately one-fifth of the world's oil and gas supply travels. The waterway has been largely closed since fighting erupted on February 28, drawing in Israeli, American, and Iranian military forces. Friday's escalation unfolded through competing accusations: Iran alleged that the US had struck an Iranian oil tanker and civilian areas; the US military said its strikes were retaliatory, responding to Iranian fire on American naval vessels the day before.

President Trump told reporters Thursday evening that the ceasefire remained technically in effect — a statement that strained credulity as the exchange of fire continued. A peace proposal remained on the table, though it left unresolved the American demand to reopen the strait and the question of Iran's nuclear program. Despite Friday's jump, both benchmarks were still on track for weekly declines of roughly 6 percent, a measure of how quickly the earlier optimism had dissolved.

A separate and troubling dimension has emerged alongside the market volatility. The US Commodity Futures Trading Commission is investigating approximately $7 billion in oil trades placed ahead of President Trump's key public statements — announcements in which he either paused military action or declared the ceasefire. The trades were largely short positions, bets that prices would fall, executed on major exchanges before Trump's words sent oil lower. The investigation asks a question that markets and the public alike are now sitting with: whether someone with foreknowledge of those statements used them to engineer a profit from a moment of global crisis.

Oil markets jolted higher on Friday as fresh fighting between the United States and Iran threatened to unravel a month-long ceasefire that had begun to ease one of the world's most consequential supply bottlenecks. Brent crude climbed to $101.47 a barrel, up $1.41, while West Texas Intermediate rose to $95.93, each gaining roughly 1.2 percent in early trading. The moves reversed three consecutive days of price declines that had followed optimistic reports earlier in the week suggesting the two countries were nearing agreement on a deal to end hostilities and restore full passage through the Strait of Hormuz.

The strait, a narrow waterway between Iran and Oman, carries roughly one-fifth of the world's oil and gas supply. It has been largely closed since fighting erupted on February 28, when Israeli strikes joined American and Iranian military operations in a widening conflict. The economic weight of that closure cannot be overstated—any disruption to energy flows through those waters reverberates instantly across global markets and into the fuel tanks and heating bills of ordinary people thousands of miles away.

Friday's escalation began with competing accusations. Iran's military claimed the United States had attacked an Iranian oil tanker, another vessel, and civilian areas both in the strait and on the Iranian mainland. The U.S. military countered that its strikes were responses to Iranian fire directed at American naval ships transiting the waterway on Thursday. The exchange of fire occurred as Washington waited for Tehran's formal response to the latest peace proposal on the table—a proposal notably silent on several contentious issues, including the American demand to reopen the strait and the broader question of Iran's nuclear program.

President Trump told reporters on Thursday evening that the ceasefire remained technically in effect, even as bullets and missiles were being exchanged. That statement captured the strange limbo the situation occupies: a formal agreement that is simultaneously being violated, a peace that is actively breaking apart. Analysts watching the market noted that the supply picture remains fundamentally constrained. Without the strait fully open, the world's oil market operates under artificial scarcity, and any hint of renewed conflict tightens that noose further.

The week's broader price action tells its own story. Despite Friday's jump, both Brent and WTI are tracking toward declines of roughly 6 percent for the week—a reflection of the earlier optimism about a deal that has now evaporated. Markets had briefly believed the worst might be behind them. That belief lasted only days.

Beyond the immediate price movements, a separate investigation has begun to cast shadows over the trading activity surrounding these geopolitical events. The U.S. Commodity Futures Trading Commission is examining oil trades totaling $7 billion that occurred ahead of President Trump's key announcements about the conflict—statements in which he either delayed military action or announced the ceasefire itself. The bulk of these trades were short positions, bets that prices would fall, placed on major exchanges including the Intercontinental Exchange and the Chicago Mercantile Exchange. Those positions profited handsomely when Trump's words sent oil prices downward. The investigation raises an uncomfortable question: whether someone with advance knowledge of the president's statements was positioning themselves to benefit from the market moves that would follow.

On the supply front, the picture remains tight. A peace deal remains elusive.
