Brent crude opens lower at $110.68 amid Iran-US tensions and Strait of Hormuz closure

Markets stepped back from the edge, but only barely.
Brent crude fell on Iran's peace proposal, yet June futures remained elevated, signaling traders' lingering uncertainty.

In the first days of May 2026, global oil markets found a moment of uneasy pause as Brent crude eased to $110.68 a barrel — a modest retreat from recent highs, prompted by Iran's tabling of a new diplomatic proposal toward the United States. Yet beneath the surface calm, two months of effective closure in the Strait of Hormuz had already reshaped the energy landscape in ways reminiscent of the early days of the Ukraine war, with June futures trading above $120 signaling that the world's traders were far from convinced the crisis had passed. It is a familiar human tension: the fragile hope carried by a diplomatic gesture, suspended against the weight of a chokepoint that history has always known how to exploit.

  • Two months of Strait of Hormuz closure have drained global supply chains to their limits — refineries are drawing reserves, strategic stockpiles are being tapped, and tankers are rerouting around Africa at enormous cost.
  • June futures trading above $120 per barrel reveal a market that does not believe the crisis is over, even as spot prices settle near $108 — a $12 spread that speaks louder than any official statement.
  • Iran's new peace proposal sent crude prices down roughly 2 percent in a single session, a collective exhale from traders who had been bracing for further escalation.
  • Every word from Washington or Tehran now moves markets — the diplomatic channel is open, but it is narrow, and a single miscalculation could close it.
  • The world is managing the energy shock, but only barely, and only at price levels that are beginning to compress economies built on the assumption of affordable oil.

Oil markets opened May in cautious retreat. Brent crude began trading at $110.68 a barrel — down from recent peaks — after Iran tabled a new peace proposal toward the United States, offering traders a reason, however tentative, to step back from the edge.

The relief was real but incomplete. For two months, the Strait of Hormuz had been effectively closed, cutting off the waterway through which roughly one-fifth of the world's oil normally flows. That disruption had pushed prices to levels unseen since Russia's invasion of Ukraine. Spot prices hovered near $108, but June futures were trading above $120 — a premium that reflected deep uncertainty about whether the strait would reopen, and when.

The consequences were already accumulating. Refineries were drawing down reserves. Strategic petroleum stockpiles in consuming nations were being tapped. Shipping routes had been rerouted around Africa, adding weeks and cost to every cargo. The global system was holding, but only under strain.

Iran's diplomatic gesture introduced the possibility that the crisis was not yet locked in place. Markets responded with a 2 percent decline — a collective exhale. Yet the wide gap between spot and futures prices told a different story: traders were still hedging against collapse, still positioned for the next escalation. The oil world was watching every statement from both capitals, ready to move sharply in either direction the moment the next signal arrived.

Oil markets opened the first week of May in a state of cautious retreat. Brent crude, the global benchmark, began trading at $110.68 a barrel—down from where it had climbed in recent weeks. The pullback came as traders parsed fresh signals from Tehran: Iran had tabled a new peace proposal aimed at the United States, a diplomatic gesture that seemed to ease, at least momentarily, the prospect of further escalation.

But the underlying anxiety remained intact. For two months, the Strait of Hormuz—the narrow waterway through which roughly one-fifth of the world's oil passes—had been effectively closed. That closure alone was enough to keep prices elevated in a way they hadn't been since Russia's invasion of Ukraine upended global energy markets. Spot prices had settled around $108, but the real pressure was visible in the futures market: traders were paying more than $120 per barrel for oil to be delivered in June, a premium that reflected genuine uncertainty about whether the strait would reopen and when.

The mathematics of the situation were stark. Two months without normal flow through that chokepoint meant global supply had tightened dramatically. Refineries were drawing down reserves. Strategic petroleum reserves in consuming nations were being tapped. Shipping routes were being rerouted around Africa, adding weeks to transit times and cost to every cargo. The world was managing, but only barely, and only at prices that were beginning to strain economies dependent on affordable energy.

What made the moment delicate was the diplomatic dimension. Iran's new proposal suggested that negotiation might still be possible—that the crisis, while real, was not necessarily locked into an irreversible trajectory. Markets responded to that signal by stepping back from the edge. The 2 percent decline in crude prices on the day of the proposal reflected a collective exhale: perhaps the worst-case scenario could be avoided.

Yet investors remained positioned for volatility. The gap between spot prices and June futures—that $12-per-barrel spread—was not the behavior of a market confident in stability. It was the behavior of traders hedging against the possibility that talks would collapse, that the strait would remain closed, that the next escalation was only a miscalculation away. Every statement from Washington or Tehran would move prices. Every report of a ship delayed or a tanker rerouted would ripple through the market. The oil world was watching and waiting, holding its breath, ready to move sharply in either direction depending on what came next.

Why did prices fall if the situation is so precarious? Shouldn't tension push them higher?

Model

Because markets price in probability, not just risk. Iran's peace proposal shifted the odds—suddenly the market saw a path where this doesn't spiral. That's worth money.

Inventor

But the Strait is still closed. Two months. That's not a small thing.

Model

It's not. The closure is real and ongoing. What changed is the narrative about whether it stays closed. If traders believe diplomacy might work, they'll sell some of their hedges. They're still nervous—look at June futures at $120—but they're not panicking today.

Inventor

So the $12 spread between now and June is pure geopolitical insurance?

Model

Essentially, yes. It's traders saying: we think this might get resolved, but we're not betting our portfolio on it. If talks fail, we want to own oil for later delivery at a locked-in price.

Inventor

What happens if the proposal goes nowhere?

Model

Then you'd expect to see those June prices climb higher, and spot prices follow. The market would be pricing in an extended closure, maybe escalation. That's when you see real pain in energy-dependent economies.
