The strait has been effectively closed since the war began
Two months into an unresolved conflict between the United States and Iran, President Trump's public rejection of Tehran's ceasefire proposal has reminded global markets how fragile the current pause in hostilities truly is. The Strait of Hormuz — a narrow passage through which one-fifth of the world's energy flows — remains closed, and oil prices have climbed back above $100 a barrel as a consequence. In the long arc of great-power rivalry over energy and nuclear ambition, this moment reflects how quickly the distance between negotiation and escalation can collapse.
- Trump declared Iran's ceasefire proposal — delivered through Pakistani intermediaries — 'totally unacceptable,' shattering hopes of a near-term diplomatic breakthrough.
- Brent crude surged 4.1% to $105.50 a barrel within hours, as markets absorbed the reality that the Strait of Hormuz blockade has no clear end date.
- The core demands of both sides remain irreconcilable: Washington insists on free passage through Hormuz and a halt to nuclear enrichment, while Tehran seeks a full cessation of hostilities and security guarantees.
- A ceasefire technically holds, but its indefinite extension provides no structural stability — sporadic firefights continue and the strait stays closed, forcing costly rerouting of global energy shipments.
- Saudi Aramco, whose pipeline network bypasses Hormuz entirely, posted a 25% profit surge, illustrating how the crisis is simultaneously devastating for some and extraordinarily lucrative for others.
Oil markets jolted sharply higher on Monday after President Trump publicly dismissed Iran's latest peace proposal as completely unworkable. The offer, conveyed through Pakistan as a diplomatic intermediary, had called for an immediate halt to hostilities and security assurances against further American or Israeli strikes on Iranian soil. Trump's rejection — delivered via social media — was swift and unambiguous, sending Brent crude up 4.1% to $105.50 a barrel and American crude up 4.4% to $99.80.
The deeper anxiety driving those numbers is the Strait of Hormuz, which has been effectively closed since the conflict began in late February. Iran has threatened to strike any vessel attempting passage, a response to American and Israeli attacks on Iranian targets. The strait normally carries roughly one-fifth of all global oil and gas shipments, and its closure has forced energy companies into expensive, complicated rerouting operations that show no sign of ending soon.
The negotiating gap between the two sides remains wide. Washington has anchored its position on two demands: restored freedom of navigation through Hormuz and a halt to Iranian nuclear enrichment. Israeli Prime Minister Netanyahu has gone further, insisting that Iran's enriched uranium stockpiles must be eliminated before any war can end. Tehran, by contrast, sought a full ceasefire and guarantees of its own security — terms Washington found unacceptable.
A ceasefire has nominally held since early April, extended indefinitely by Trump on April 21 to give Iran time to present a unified proposal. That proposal has now been rejected, leaving the fundamental question unanswered: whether this is tactical maneuvering ahead of further talks, or a genuine collapse of the negotiating process. For Saudi Aramco, whose Hormuz-bypassing pipeline network has become what its CEO called a 'critical supply artery,' the volatility has meant a 25% jump in first-quarter profits. For the rest of the world, the closed strait and climbing prices are a daily reminder that the impasse has yet to find its resolution.
Oil prices spiked sharply on Monday morning across Asian markets after President Trump dismissed Iran's latest proposal to end the war as completely unacceptable. The Iranian response, delivered through Pakistan acting as intermediary, had called for an immediate halt to hostilities and assurances that neither the United States nor Israel would launch further attacks on Iranian territory. Trump's reaction was swift and public: a social media post declaring the terms unworkable.
The market response was immediate. Brent crude, the international benchmark, climbed 4.1 percent to $105.50 a barrel. American crude rose 4.4 percent to $99.80. These moves reflected a fundamental anxiety coursing through energy markets—that the conflict between the US and Iran, now running for more than two months, shows no clear path toward resolution.
At the heart of the standoff lies the Strait of Hormuz, one of the world's most critical chokepoints for energy. Roughly one-fifth of all global oil and gas shipments normally flow through these waters. Since late February, when the war began, the strait has been effectively closed. Iran has threatened to attack any vessels attempting passage, a retaliation for American and Israeli strikes on Iranian targets. The blockade has created a cascading disruption across global energy supplies, forcing companies to reroute shipments at considerable cost and complexity.
The American negotiating position, according to reporting, centered on two core demands: restoration of free passage through the Hormuz and a halt to Iranian nuclear enrichment activities. Israeli Prime Minister Benjamin Netanyahu reinforced this stance, declaring that the war cannot end until Iran's enriched uranium stockpiles are eliminated. These conditions appear to have been non-starters for Tehran, which sought instead a complete cessation of hostilities and security guarantees.
A ceasefire had been in place since early April, largely holding despite sporadic firefights. Trump extended that truce indefinitely on April 21, explicitly giving Iran time to formulate what he called a "unified proposal." The Iranian response, delivered this week through Pakistani channels, appears to have fallen short of what Washington was willing to accept. The rejection signals that fundamental gaps remain between the two sides on what a lasting settlement would require.
For major energy companies, the volatility has been extraordinarily profitable. Saudi Aramco reported earnings up more than 25 percent in the first quarter compared to the same period last year. The company's cross-country pipeline network, which bypasses the Strait of Hormuz entirely, has become what its chief executive Amin Nasser called a "critical supply artery," insulating Aramco from the disruptions hammering competitors dependent on traditional shipping routes. Other major energy firms have similarly benefited from the price surge, even as the blockade constrains their ability to move product to market.
With Trump's rejection of Iran's terms now public, the question facing markets is whether the negotiating process has genuinely stalled or whether this represents tactical positioning ahead of further rounds of talks. The ceasefire remains in place, but its indefinite extension offers no guarantee of permanence. Energy prices have already climbed back above $100 a barrel since the April truce took effect, and they could move higher still if the conflict reignites or if negotiations collapse entirely. The Strait of Hormuz remains closed, a physical manifestation of a diplomatic impasse that shows no immediate signs of breaking.

I don't like it - TOTALLY UNACCEPTABLE— President Trump, responding to Iran's proposal via social media
The war with Iran will not be over until its enriched uranium stockpiles are taken out— Israeli Prime Minister Benjamin Netanyahu
La Conversación del Hearth Otra perspectiva de la historia
Why did Trump reject the proposal so publicly? Couldn't that have been handled quietly?
The public rejection signals resolve to his domestic audience and to Israel. It also puts pressure back on Iran—showing he won't accept terms he views as weak. But yes, it also eliminates any room for face-saving negotiation.
What does Iran actually want that's different from what the US is offering?
Iran wants the war to stop and guarantees it won't happen again. The US wants the strait reopened and Iran's nuclear program rolled back. Those aren't easily reconciled—one side sees security, the other sees surrender.
How long can the Strait stay closed before it breaks the global economy?
It's already broken something. Energy companies are making record profits, but that's because prices are sky-high. Consumers everywhere are paying more. If it stays closed for months, you start seeing real economic damage beyond just expensive oil.
Is Aramco's success here a sign that the blockade might become permanent?
It's a perverse incentive. Aramco profits from scarcity. If the strait reopened tomorrow, prices would fall and their windfall would evaporate. That doesn't mean they caused the blockade, but it does mean some actors benefit from it staying closed.
What happens if Trump and Iran can't find common ground?
The ceasefire was extended indefinitely, but indefinite isn't forever. If talks collapse, you could see fighting resume. That would likely close the strait even tighter and send oil past $120 or higher.
