Oil Prices Surge Nearly 5% as Hormuz Opening Hopes Collapse Under Iran-US Demands

Strait of Hormuz Stalemate Sends Crude Futures Soaring

Global oil benchmarks rocketed higher on Monday, closing roughly 5% up after Iran attached a list of preconditions to reopening the Strait of Hormuz, dashing market hopes that the critical waterway would soon resume normal traffic. Brent crude settled at $87.72 a barrel, gaining $4.17, while US West Texas Intermediate added $3.95 to close at $82.13.

The rally reversed much of last week’s 7% slide that had been driven by signals Iran and Oman were nearing a deal to free the strait, through which roughly one-fifth of the world’s oil and liquefied natural gas used to pass before the Middle East conflict escalated in late February. On Sunday, Iran stated that talks with Muscat had reached “final stages” but insisted that Washington must first lift sanctions, pay Tehran compensation for its large-scale attacks and meet other conditions before the chokepoint reopens. Iranian Foreign Minister Abbas Araghchi also said no direct US-Iran talks were underway and that Tehran would not engage while Washington was violating a temporary agreement signed in June.

Separately, the White House added its own financial demand, with President Donald Trump saying Iran must pay compensation for “all the people it killed or severely injured.” The hardening of positions on both sides punctured the tentative optimism that had built in oil markets the previous week.

Renewed supply threats multiplied the risk premium. Iran-aligned Houthi forces claimed a Sunday attack on Saudi Aramco’s Jazan refinery, just two days after Riyadh signed a defence pact with Turkey and Pakistan aimed at containing the worsening regional turmoil from the US-Israeli military campaign against Iran. Abu Dhabi National Oil Company (Adnoc) disclosed that 15 of its vessels had been hit while transiting the Strait of Hormuz since the conflict began, underlining the physical danger to Gulf crude exports.

Why the Hormuz Impasse Has Oil Markets on Edge

Iran’s negotiation playbook: no opening without sanctions relief

Iran is using the Strait of Hormuz as its single strongest bargaining chip. By framing the reopening as conditional on the US lifting sanctions, paying reparations and honouring a fragile June interim deal, Tehran is trying to extract the concessions it could not secure on the battlefield. The demand that Washington compensate for “large-scale attacks” mirrors its own narrative of victimhood and is almost certainly unacceptable to the Trump administration, making a swift diplomatic breakthrough unlikely.

The Trump counter-demand freezes the diplomatic track

President Trump’s demand for compensation for American casualties amounts to a mirror-image ultimatum that deepens the impasse. With neither side willing to compromise first, the prospect of a near-term reopening of the strait looks remote. Oil markets are repricing that reality, removing last week’s speculative easing of the risk premium and adding back the full supply-disruption discount.

Maritime security risks are rising, not fading

Adnoc’s disclosure that 15 of its ships have been attacked in the strait since the conflict erupted provides a concrete corporate warning. Unlike abstract threats, the Adnoc data shows that commercial operators are absorbing real losses even outside periods of all-out blockade. When combined with the Houthi strike on Jazan, it signals that the theatre of attacks is expanding from the Gulf of Aden and the Red Sea to the Gulf of Oman and the Strait itself, directly targeting the infrastructure and logistics of major Gulf producers.

Saudi Arabia’s new defence pact shifts regional calculus

The defence agreement with Turkey and Pakistan, signed just days before the refinery attack, suggests Riyadh is bracing for a protracted period of Iranian-aligned disruptions. While the pact bolsters Saudi deterrence, it also raises the risk of further escalation, as any Houthi or Iranian attack could now draw in two major regional militaries under a mutual defence umbrella. For oil markets, that adds a second-order geopolitical layer that can keep supply fears elevated even if the Hormuz deadlock shows signs of easing.

Who gains and who loses from a prolonged closure

Gulf producers such as Saudi Arabia, the UAE and Kuwait face immediate logistics and insurance cost spikes, and potential production shut-ins if shipping routes cannot be secured. Asian importers heavily reliant on Middle East crude — Japan, South Korea, India — will see higher delivered prices and may accelerate diversification toward Atlantic Basin barrels. US shale producers, Russian and West African exporters could capture market share, though the net supply loss from Hormuz bypassed would still tighten global balances.

What Energy Buyers, Shippers and Risk Managers Need to Watch

For energy buyers

• Evaluate the availability and cost of alternative crude grades (US WTI, North Sea, West African) given that Hormuz-dependent flows could remain restricted for weeks or months.
• Factor a sustained $5-8 per barrel risk premium into medium-term procurement budgets for Middle Eastern crude until concrete de-escalation steps are visible.

For shipping and logistics operators

• Assess vessel insurance costs for transits near the Strait of Hormuz and the Gulf of Oman; Adnoc’s 15-ship loss tally suggests premiums will rise further.
• Review charters and force majeure clauses to prepare for potential voyage delays if the strait remains blocked or if naval escorts become compulsory.

For investors and risk managers

• Watch the Iran-Oman diplomatic track closely: the “final stages” claim is the single most tradeable headline. Any joint statement between Muscat and Tehran, even if conditional, could trigger sharp oil sell-offs.
• Monitor Saudi-led defence pact statements and any Houthi reprisals; a direct military clash involving Turkish or Pakistani forces would lift the geopolitical risk premium beyond current levels.
• Keep an eye on US-Iran back-channel signals through Swiss or Omani intermediaries; even a small reciprocal gesture on sanctions could reverse the price spike.
