Oil Prices Plunge as U.S., Iran Pause Strikes Around the Strait of Hormuz

Oil markets posted their sharpest one-day drop in over a week Monday after the United States and Iran both stepped back from a two-week exchange of strikes around the Strait of Hormuz, a pause now being tested by drone attacks on three of Iran's neighbors within 48 hours of taking effect. Brent crude, the international benchmark, settled down roughly 8.6% to about $88.49 a barrel, while U.S. West Texas Intermediate fell about 7.7% to $82.43, according to CNBC's market close figures. Both benchmarks are now well off the $102-a-barrel peak Brent touched last week, the highest level since May, when the conflict's spillover into Red Sea shipping lanes pushed prices up more than 9% in a single week. President Trump told reporters aboard Air Force One the U.S. was having "good talks" with Tehran, while Iran's government has publicly maintained it is not seeking new negotiations and still controls terms of passage through the strait. Behind the public statements, Iran and Oman spent the weekend in technical talks over a compromise on vessel transit, and airline stocks, including Seattle-area Alaska Air Group, rallied on the same relief that pulled crude prices down.

A Trading Day That Moved Twice

Oil's decline was not a single, smooth move. Early Monday trading, captured in a Euronews report published during the session, had Brent for September delivery down 4.66% to $92.27 and WTI off 5.02% to $84.83. By the close of trading, both benchmarks had fallen roughly twice as far. Brent touched an intraday low of $87.60, a 9% drop from Friday's close, before settling around $88.49; the broader session saw prices dip as low as $87.60 and recover slightly to close near $90.80 before final settlement figures put Brent at $88.49. The gap between the mid-session and closing figures is not a discrepancy between outlets so much as a snapshot of a market that kept sliding through the day, as traders priced in confirmation that both Washington and Tehran intended to hold their pause rather than treat it as a brief lull between rounds of strikes. That pattern, a fast initial move followed by a deeper slide as the session wears on, has become familiar over five months of trading tied to this war. Oil desks have learned to treat the first hour of a post-announcement session as an incomplete read, since the early print typically reflects only the traders positioned to react within minutes of a headline, while the fuller repricing that follows takes most of a trading day to work through as more desks confirm the news and adjust. For a reader trying to reconcile two headlines published hours apart, that is the practical lesson: a mid-session percentage and a closing settlement price are both accurate, they are just answers to slightly different questions, and only the settlement figure is what actually determines contract values and the next day's opening price.

Why Prices Fell This Fast

The proximate trigger was Iran's signal, relayed through intermediaries, that it would suspend its own attacks for as long as the U.S. pause in hostilities held. That eased the specific fear that had driven Brent above $100 the previous week: a prolonged closure or slowdown of traffic through the Strait of Hormuz, the narrow waterway off Iran's southern coast through which roughly a fifth of the world's oil typically moves. NBC News reported the pause reflects a decision by Trump's military advisers, who told the president the bombing campaign was running out of viable targets rather than reflecting any breakthrough at the negotiating table. That distinction matters for how durable traders expect the price relief to be: a pause driven by a depleted target list can end the moment new targets are identified, while a pause driven by an actual diplomatic accord tends to hold longer. Markets priced in relief Monday, but the underlying dispute over who controls the strait remains unresolved. Crude futures traders are effectively betting on the same question shipping companies are: not what Washington and Tehran say publicly on a given day, but whether tanker traffic through the strait actually resumes at something close to pre-war volumes in the coming days, and stays there long enough to be treated as the new normal rather than a lull. Vessel tracking data was not immediately available Monday to confirm whether shipping traffic through the strait had actually picked up, which means Monday's price move reflects expectations about what will happen this week more than confirmation of what has already happened, a distinction that matters if the pause breaks down before those expectations are tested against real cargo movements.

Adm. Cooper's Assessment That Changed the Calculus

The bombing pause traces to a specific recommendation from Adm. Brad Cooper, the U.S. Central Command chief, who told Pentagon leadership and the White House that the two-week campaign against targets around the strait and Iran's southern coast had reached the limits of what continued strikes could achieve without a decision to escalate substantially. Most of the designated targets in the region had already been hit, according to Cooper's assessment, leaving few objectives that justified the continued risk. Trump acted on that recommendation Friday, suspending the campaign in what he described Monday as an opening to see whether "something could happen" diplomatically, while warning that strikes would resume if talks failed to produce results within an unspecified window. Cooper's assessment carried particular weight because it came from the officer with the clearest operational view of what remained on the target list, rather than from a political adviser weighing the campaign's cost in headlines or approval ratings. When the commander responsible for identifying targets tells the White House there are few left worth hitting, that is a harder recommendation for a president to override than one framed purely in diplomatic terms, and traders read Friday's suspension accordingly as a genuine operational pause rather than a symbolic gesture timed to news cycles. Cooper's advice was not delivered in isolation. Other senior officers reportedly reinforced the same conclusion to Pentagon leadership and the Joint Chiefs, which is part of why the recommendation moved as quickly as it did from an internal military assessment to a presidential decision announced within days rather than the weeks such reversals have sometimes taken earlier in the conflict. The White House has not disclosed how many targets CENTCOM had identified at the campaign's outset or how many remained by Friday, so the public is left to take Cooper's assessment on its face rather than verify it against a published target list, the same transparency gap that has shaped much of the coverage of this war's second phase.

The Compromise Taking Shape in Muscat

Behind the public statements, Iran and Oman have held several rounds of technical talks over the weekend aimed at a compromise on how vessels transit the strait, according to a regional official involved in the mediation who was not authorized to speak publicly. The proposal under discussion would let Iran manage vessel transit through the strait with fewer restrictions than the U.S. and Gulf shipping interests initially sought, addressing a dispute that dates to the interim ceasefire Iran and the U.S. signed in June. Under that earlier deal, Iran began requiring ships to route closer to its coastline and signaled it might charge transit fees, terms Washington and shipping companies rejected as functionally giving Tehran control over a waterway that carries roughly a fifth of global oil supply. Iran's Foreign Ministry spokesperson, Esmail Baghaei, said the talks with Oman "made progress" and were continuing, even as Tehran's public position remains that it is not seeking broader talks with Washington. Oman's role here is not new. The sultanate has served as the primary back-channel between Washington and Tehran through most of the past decade, in part because it maintains working relationships with both governments that few other regional states can claim, and in part because a significant share of the shipping that transits the Strait of Hormuz also passes within sight of Oman's own coastline, giving Muscat a direct economic stake in a settlement that keeps the waterway open. Neither Washington nor Tehran has said publicly how close the two sides are to signing anything, and the anonymous sourcing behind the reported terms, an unnamed regional official rather than an on-record statement from either government, is itself a signal that the talks remain sensitive enough that neither side wants to be seen confirming details before an agreement is final. That caution cuts both ways: it protects the talks from becoming a political target in either capital, but it also means the public has no way to independently verify how far along the negotiations actually are.

Drones Test the Pause Within Two Days

The diplomatic window opened Friday was already under strain by Monday. Saudi Arabia, Jordan and Iraq each reported drone attacks, with Saudi Arabia saying it shot down drones aimed at petroleum targets in its eastern province and in the capital, Riyadh. Saudi officials said the drones were launched from Iraq by an Iran-backed militia and reserved the right to respond. None of the three governments has directly accused Tehran of ordering the strikes, but the timing, arriving within 48 hours of the U.S. bombing halt, has been widely read across the region as Iran-aligned forces testing how far the pause extends before Washington re-engages. A second attack on shipping or petroleum infrastructure in the coming days would likely reverse Monday's price relief quickly, given how directly Brent and WTI have tracked the on-again, off-again status of the strikes since February. What makes Monday's incident harder to read than earlier ones is the choice of target. Petroleum infrastructure in Saudi Arabia, rather than shipping in the strait itself, sits closer to the kind of strike that could pull Riyadh directly into the conflict as a combatant rather than a bystander, a step none of the parties involved in the Oman talks have publicly signaled they want to see happen while the diplomatic track is still active. Jordan and Iraq's reported drone incidents were smaller in scale and drew less detailed public accounting than Saudi Arabia's, which named specific targets in its eastern province and capital, a gap in disclosure that makes it difficult to assess Monday's full picture from public statements alone. What is consistent across all three reports is the timing: each arrived within the same 48-hour window after Washington's bombing halt, which is the detail regional analysts have focused on rather than the individual attacks themselves.

The Washington Connection: Alaska Air's Rough Year

The clearest Pacific Northwest tie to Monday's oil move sits in downtown SeaTac, where Alaska Air Group is headquartered. The airline was among the carriers posting premarket gains of roughly 2.9% to 4% Monday as crude fell, part of a broader rally that also lifted Delta, United, American, Southwest and JetBlue on hopes that cheaper fuel would ease months of margin pressure. Alaska Air's exposure to this specific war is not incidental. The company withdrew its full-year 2026 financial guidance on April 20, citing the unpredictable swings in oil prices the Iran conflict had already caused at that point, four months before Monday's pause. Jet fuel, which traded near $2.50 a gallon before the war began in February, peaked at $4.88 a gallon in early April, according to market data reported alongside Monday's rally. Monday's stock gain reflects relief, not resolution. Morningstar analyst Nicolas Owens has noted that airlines that already sold tickets under higher fuel-cost assumptions do not recover margin the moment crude drops, since a single day's price move works through the business only gradually. For a Seattle-area employer that grounded its own financial forecast over this war, a one-day pause in strikes is a reason for cautious optimism, not a reason to reissue guidance. Alaska Air's guidance withdrawal in April was notable because it broke from the airline's usual practice of maintaining forward earnings estimates through most disruptions, a step the company attributed specifically to unpredictable swings in oil prices tied to the war rather than to any weakening in the underlying business. That distinction, volatility rather than deterioration, is part of why Monday's rally in Alaska Air shares reads as a bet on stability returning to fuel markets rather than a bet that the airline's core demand has improved.

What a Five-Month War Has Cost the Global Economy So Far

The conflict that began Feb. 28 has now run nearly five months, moving through at least two prior ceasefires that collapsed within weeks and a pattern of bombing campaigns paused and resumed on the recommendation of military commanders rather than diplomatic breakthroughs. Each escalation has moved oil prices by high single-digit or low double-digit percentages within days, a volatility that has become its own economic story independent of the military campaign's outcome. Brent's round trip from roughly $70 before the war, to above $100 during last week's escalation, back to $88 Monday illustrates how sensitive global energy markets remain to a single narrow shipping channel and a conflict that has repeatedly defied predictions of either a quick resolution or a permanent breakdown. Every prior pause in this war, in April and again in June, produced a version of Monday's relief rally before the fighting resumed and prices climbed back toward their highs, a pattern close enough to a habit by now that traders openly discount how long any single pause is likely to last. Whether Monday's price relief holds depends less on Monday's numbers than on whether the Oman-mediated talks produce a durable framework before the next target list runs out and the bombing resumes, and on whether the drone attacks reported Monday in Saudi Arabia, Jordan and Iraq turn out to be an isolated test of the pause or the opening move of the next round. For a conflict that began with a decapitation strike against Iran's supreme leader and has since cycled through at least three named phases of escalation and de-escalation, the pattern by now is familiar enough that few analysts are treating Monday's relief rally as evidence the war is actually ending. It is evidence, instead, that global energy markets have adapted to pricing this specific war's rhythm almost in real time, rewarding every pause with a rally and every resumption with a spike, regardless of how many times that cycle has already repeated.
