Iran, US clash over Gulf shots as 21% of oil trade at risk

Iran said its navy fired warning shots at two US destroyers in the Gulf of Oman on Friday, a claim the Pentagon denied, as an explosion at an Omani oil terminal halted loading.

"Iranian forces did not attack US warships or open fire," US Central Command said in a statement, directly contradicting Tehran's account that its navy forced the vessels to retreat to the Indian Ocean.

The standoff unfolded near the Strait of Hormuz, a chokepoint that handles about 21% of global crude shipments, according to the US Energy Information Administration. Oman's Mina al Fahal terminal suspended oil loading after an explosion near its single-buoy mooring berths, which two people familiar with the matter attributed to a drone attack. The terminal could not be reached for comment outside office hours.

Any disruption to shipping through the Strait of Hormuz carries outsized consequences for global oil markets. The last time Iran and the US engaged in a similar escalation in the Persian Gulf — the May 2019 tanker attacks off Fujairah — Brent crude jumped about 5% in three days before the premium faded as no sustained supply disruption materialized. This time, the conflicting claims add uncertainty that could keep the risk bid in place until independent verification resolves the dispute.

Strait of Hormuz Risk Premium Returns

Brent crude futures rose as traders assessed the probability of a broader confrontation that could affect tanker traffic through the 21-mile-wide waterway. The strait carries about 17 million barrels of oil per day, or roughly one-fifth of global consumption, according to the EIA. Iran has previously threatened to close the strait in response to heightened tensions with the US, though it has never followed through.

The risk premium in oil options widened Friday, with implied volatility on Brent at-the-money contracts rising as traders hedged against the possibility of a supply outage. War risk insurance premiums for tankers transiting the region also increased, according to shipping sources, adding to the cost of moving crude through the waterway. Defense sector stocks gained, with Lockheed Martin and RTX Corp. both rising in pre-market trading as investors rotated into names that benefit from elevated geopolitical risk.

Conflicting Narratives Complicate Market Pricing

The dueling accounts from Washington and Tehran leave traders without a clear factual baseline — a scenario that historically favors the risk-off trade until verified information emerges. Iran's state-aligned media outlets promoted the warning-shot narrative, while US Central Command released no imagery or additional details to support its denial.

"The market is pricing in a tail risk that neither side has an incentive to de-escalate quickly," said Helima Croft, head of commodity strategy at RBC Capital Markets. "Until we get independent confirmation of what happened, the premium will stay in the curve."

Gold rose as investors sought safe-haven assets, while the US dollar strengthened against emerging-market currencies exposed to energy import costs. The broader risk-off tone weighed on equity index futures, with the S&P 500 and Nasdaq both pointing to a lower open. The VIX, Wall Street's fear gauge, edged higher as options traders priced in increased tail risk across US equities.

If the situation de-escalates in the coming days — as it did after the 2019 Fujairah attacks — the risk premium could unwind quickly, potentially reversing much of Friday's move. But if further incidents occur, or if Iran follows through on past threats to disrupt shipping, the premium could persist for weeks. The next 48 hours are critical: satellite imagery of the Mina al Fahal terminal and any additional statements from either government will determine whether this is a one-day event or the start of a sustained period of elevated risk in the world's most important oil chokepoint.
