Crude oil notched its third consecutive session of gains on Tuesday, as hopes for a negotiated end to the six-month-old Middle East war continued to fade.
Tehran’s declaration that it would pivot to a “fully offensive” military posture, combined with Washington’s refusal to extend its fragile ceasefire arrangement with Iran, has left traders bracing for a conflict with no clear off-ramp and a Strait of Hormuz that remains only partially open for business.
By 08:27 GMT, Brent crude futures had added 35 cents, or 0.39%, to trade at $91.22 a barrel, while U.S. West Texas Intermediate crude rose 81 cents, or 0.96%, to $85.31.
Both benchmarks touched their highest levels since late July during the session, extending a rally that has quietly rebuilt the geopolitical risk premium markets and had begun to strip out of oil prices just weeks earlier.
The reversal marks a stark shift in sentiment. As recently as early July, Brent had slumped to roughly $70 a barrel, its lowest level since the war’s opening days on reports of “positive progress” in indirect U.S.-Iran talks mediated by Qatar, with prices down more than a third from their post-war peak above $126 struck at the end of April. That optimism has since evaporated.
A 60-day window set aside for negotiators to hammer out a lasting settlement expired this past weekend without a breakthrough, and President Trump has signaled he has no intention of extending the ceasefire that has loosely governed the conflict since it erupted on February 28.
“Sentiment remained supported by U.S. President Donald Trump’s decision not to extend the US-Iran peace agreement and continued security concerns in the Strait of Hormuz,” ING analysts wrote in a client note Tuesday, capturing what has become the market’s dominant narrative: a war that once seemed to be winding down is instead entering a more volatile, less predictable phase.
The clearest signal of that shift came Monday, when a senior Iranian official told Reuters that Tehran would move to a fully offensive footing, having concluded that diplomatic efforts toward a permanent settlement had stalled beyond repair.
The statement effectively closes the door, at least for now, on the kind of negotiated de-escalation that briefly buoyed markets over the summer.
Analysts warn the implications extend well beyond the current quarter. “The lack of any kind of deal will have an impact on oil price expectations further out in 4Q and even in 2027,” said Suvro Sarkar, head of energy research at DBS Bank, suggesting traders are no longer pricing this as a short-term disruption but as a structural risk that could shape the oil market for years.
Nowhere is that risk more concentrated than in the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world’s oil consumption passes.
Tanker traffic through the strait has remained stuck in the single digits despite a modest uptick over the weekend, according to tracking data, and a projectile struck a vessel transiting out of the strait on Tuesday, the latest in a string of attacks that have kept shipowners on edge.
Not every operator has pulled back entirely. Saudi Aramco has resumed some oil loadings from within the strait and is offering cargoes via ship-to-ship transfers off Fujairah in the United Arab Emirates, a workaround that underscores both the resilience of Gulf exporters and the lengths to which they must now go to keep barrels moving.
Whether Iran escalates further remains an open question; one analyst says Tehran itself may not have fully answered. “It is probably in Iran’s power to fully halt the flow of oil out of the Strait of Hormuz whenever they find it suitable. Or they will soon have built the capability of that.
Iran is for sure not just sitting still waiting for new U.S. sanctions,” said Bjarne Schieldrop, an analyst at SEB.
A parallel diplomatic track has also frayed. Iran has been negotiating separately with Oman on an arrangement to manage traffic through the strait, and Iranian officials say the two sides are close to an agreement.
But that effort drew an unusually blunt threat from Trump, who warned he would bomb the Gulf state, a longtime U.S. security partner, if it interfered with Washington’s own efforts in the strait, according to comments published this week. The threat has rattled a region already unsettled by the prospect of the conflict spilling further beyond Iran’s borders.
The instability is not confined to the Gulf. Yemen’s Iran-backed Houthi movement said Tuesday it had launched ballistic missiles at what it described as a Saudi military vessel and four escort ships in the Red Sea, according to military spokesperson Yahya Saree, speaking on the Telegram messaging app.
The attack adds a second potential chokepoint to traders’ list of concerns, reviving memories of the shipping disruptions that plagued Red Sea routes earlier in the conflict.
For now, oil’s gains remain measured rather than panicked, a reflection, analysts say, of a market still weighing how much of the current rhetoric will translate into an actual disruption of supply versus posturing ahead of further negotiations.
But with the ceasefire lapsed, offensive postures hardening on both sides, and two separate maritime flashpoints now active, traders appear to be concluding that the risk of a prolonged, harder-to-resolve conflict has meaningfully increased and pricing oil accordingly.
WHAT YOU SHOULD KNOW
The Middle East war’s off-ramp has closed. With the U.S.-Iran ceasefire window expired, Iran shifting to a “fully offensive” posture, and tanker traffic through the Strait of Hormuz still choked to a trickle amid fresh attacks, oil’s third straight day of gains reflects one thing: markets no longer expect a quick resolution and are pricing in the risk of a longer, more dangerous conflict stretching well into 2027.
