Trump rejects Iran peace proposal, oil surges past $120: What Gulf Coast operators need to know today

Editor's note: BIC Magazine has been covering the Strait of Hormuz crisis and its implications for Gulf Coast refining, petrochemical and contractor operations since the conflict began February 28. This piece covers the most significant developments of the past 48 hours, which have sent oil prices to their highest levels since 2022. We will continue to update our coverage as this story develops.

The situation around the Strait of Hormuz deteriorated sharply this week. Trump rejected Iran's latest peace proposal on Wednesday. Oil surged past $120 per barrel Thursday morning. The U.S. naval blockade of Iranian ports is continuing indefinitely. And as of today, the UAE has officially left OPEC.

If you are running a Gulf Coast refinery, petrochemical facility or industrial contracting operation, here is the direct update on where things stand and what it means for your business.

What happened in the past 48 hours

Iran submitted a new peace proposal through Pakistani mediators this week focused on a single core trade: Iran reopens the Strait of Hormuz and the U.S. lifts its naval blockade of Iranian ports, with nuclear negotiations deferred entirely to a later stage after the war formally ends. The proposal was conveyed to Washington by Pakistan, which has been serving as the primary mediator since the April 8 ceasefire was declared.

Trump rejected it. Speaking to Axios on Wednesday, Trump said he does not love the proposal and that a deal separating the Strait reopening from the nuclear file was not acceptable. The White House confirmed that Trump and his national security team had discussed the Iranian proposal in a Situation Room meeting Monday. Secretary of State Marco Rubio was described as dismissive of any arrangement that allowed the U.S. to lift the blockade without resolving the nuclear question. The core concern from Washington's side is that lifting the blockade and ending the war without binding nuclear commitments would remove the primary source of U.S. pressure in any subsequent talks on Iran's enriched uranium stockpile.

Iran's position is equally clear. Tehran cannot reach domestic political consensus on nuclear concessions while the war is ongoing. Iranian Foreign Minister Abbas Araghchi acknowledged that the leadership is divided on what nuclear concessions should be on the table, and that the proposal to separate the Strait from the nuclear file was designed to break the diplomatic stalemate by solving the most immediate global crisis first.

The U.S. is now discussing military options and an extended blockade as part of internal planning, according to CNN reporting this morning. Trump told reporters Wednesday that the blockade is "genius" and that Iran simply needs to "cry uncle." Iran's Supreme Leader Mojtaba Khamenei marked National Persian Gulf Day today with a statement saying the future of the Persian Gulf will be one "without America."

Iran is expected to submit a revised proposal in the coming days. How much that proposal changes on the nuclear file will determine whether talks resume or break down further.

Where oil prices stand right now

Brent crude crossed $120 per barrel this morning for June contracts before paring some gains, climbing roughly 3% on Thursday as the market priced in the dual impact of the rejected peace proposal and the continued blockade. WTI briefly topped $110 per barrel. The national average U.S. gas price hit $4.30 per gallon today, up 27 cents in a single week, and up 44% since the start of the conflict in February.

The Federal Reserve's Beige Book, released two weeks ago, confirmed what Gulf Coast operators already know from their own income statements: refiners and petrochemical producers along the Gulf Coast are reporting their highest margins since 2022, driven by the Strait closure tightening global supplies of refined products and reducing output of key petrochemicals worldwide.

Goldman Sachs revised its 2026 Q4 Brent forecast upward to $90 per barrel this week, citing lower Persian Gulf output and a slower expected Gulf production recovery even in a resolution scenario. Analysts at Barclays have noted that every additional day of disruption shifts the risk balance toward higher-for-longer energy prices and, eventually, demand destruction.

What the stalled peace talks mean for Gulf Coast operators

The rejection of Iran's proposal does not change the operating environment for Gulf Coast facilities in the near term. The factors driving the current margin environment, elevated distillate cracks, strong Gulf Coast refinery utilization, competitive ethane-based feedstock economics for Gulf Coast petrochemical producers, are all still intact. A failed round of diplomacy keeps the supply disruption in place, which means the margin conditions that have benefited Gulf Coast operations since late February continue.

The more important question for Gulf Coast operators is what the medium-term path looks like. There are two scenarios worth thinking through.

In the first scenario, a revised Iranian proposal addresses at least some U.S. concerns on the nuclear file, talks resume and a partial or full Strait reopening happens over the next 60 to 90 days. In that scenario, the elevated margin environment starts to compress as Middle Eastern supply returns to market. Gulf Coast refiners and petrochemical producers would still benefit from a period of catch-up demand as inventories globally are restocked, but the peak-margin window would be closing.

In the second scenario, talks fail entirely, the blockade continues or expands and the Strait stays effectively closed through summer and into fall. In that scenario, Citi's worst-case analysis of Brent at $130 per barrel by end of June becomes more realistic. That environment continues to favor Gulf Coast refiners and ethane-fed petrochemical producers, but it introduces demand destruction risk as consumers and industrial buyers globally pull back on petroleum-derived products at sustained high prices.

The EU Energy Commissioner's assessment, shared last week, that even a best-case resolution would take more than two years to fully normalize production levels remains the most important long-term data point. The supply chain disruption is not a light switch. It does not end when the Strait reopens. The physical damage to Middle Eastern refining and production infrastructure, the shortage of available tankers and crews willing to transit, the inventory restocking cycle and the contractor availability to execute repairs all play out over months and years, not weeks.

The tariff factor nobody is talking about enough

There is a secondary cost pressure building on top of the energy price environment that deserves more attention in Gulf Coast industrial circles. Section 232 tariffs at 50% on steel and aluminum remain fully in effect, with no emergency relief related to the Hormuz disruption. Section 301 tariffs on Chinese goods also continue unchanged. For Gulf Coast contractors buying structural steel, pipe, valves, instrumentation and process equipment for capital projects and turnaround scopes, the tariff layer on top of elevated energy and materials costs is creating a compounding input cost environment that project budgets set 18 months ago did not anticipate.

The American Chemistry Council (ACC) and American Fuel and Petrochemical Manufacturers (AFPM) have been working with the administration on exemptions for specific polymer and petrochemical products, with some success. Key products including polyethylene, polypropylene, polyethylene terephthalate, phenols and ethylene are currently exempt from the universal tariff. But the steel and aluminum tariffs are creating real budget pressure on the maintenance and capital project side of the business, and that pressure shows up in contractor bid pricing, change orders and scope management conversations at facilities across the Gulf Coast.

The combined effect of elevated energy prices, Hormuz-related supply disruption and persistent tariffs on construction materials is an operating cost environment unlike anything Gulf Coast facilities have managed simultaneously in recent memory. The operators managing it best are the ones who locked in contractor relationships and material pricing earlier in the year, before the full scope of these conditions was visible.

What to watch in the next 72 hours

Iran is expected to submit a revised peace proposal within the next few days. The content of that proposal on the nuclear file will be the most important data point for energy markets and Gulf Coast operations in the near term. If the revised proposal includes even modest concessions on uranium enrichment, the probability of resumed talks increases and the market will begin pricing in some probability of a Strait reopening.

Trump has also said publicly that he prefers a deal over further military action, which introduces real possibility of a negotiated resolution even after the rejection of Wednesday's proposal. The open-ended ceasefire remains in place. The U.S. is not bombing Iran right now. The diplomatic channel through Pakistan is still open. None of that means a deal is imminent, but it means the situation is not as locked as the rejected proposal headlines suggest.

BIC Magazine will continue following this story

This is day 61 of the conflict. The Strait of Hormuz remains closed. Iran's revised proposal is expected shortly. The UAE left OPEC this morning. Oil is above $120 per barrel. Whatever happens next matters for every refinery, petrochemical facility and industrial contractor on the Gulf Coast.

We will update as things develop.
