US-Iran Ultimatum Escalates Hormuz Tensions, Oil Surges

The deadline expires Monday evening in New York, placing markets on high alert for further developments. Iran responded with a stark warning, signaling any US attack triggers a broad retaliation campaign targeting American- and Israeli-linked energy assets across the Gulf.

Officials also indicated the Strait of Hormuz could shut indefinitely, raising the risk of severe and prolonged disruption to global oil flows. Analysts confirm this standoff represents a significant escalation, with both sides willing to raise stakes rather than de-escalate.

The confrontation injected fresh geopolitical risk into energy markets, with traders bracing for further volatility. Oil prices surged into the weekend, settling at their highest level since mid-2022 on Friday.

Market participants increasingly price in sustained supply disruptions, given Hormuz's strategic importance. Since the conflict began, disruptions linked to the partial closure of the Strait have already removed an estimated 440 million barrels of supply from global markets.

Iran has targeted ports and refinery infrastructure across several Gulf states. Analysts warn damage to desalination facilities, which Iran has so far avoided, triggers a humanitarian crisis, with some Gulf cities at risk of becoming uninhabitable within weeks due to water shortages and cascading power failures.

The International Energy Agency (IEA) estimates it takes up to six months to fully restore flows, even if conditions stabilize. Reports suggest the US considers more aggressive measures, including a blockade or seizure of Iran’s key export hub at Kharg Island, further underscoring escalation risk.
