CENTCOM denies US struck Kharg Island as war talk intensifies

US Central Command issued a formal denial five days ago that American forces had struck Kharg Island, Iran's most important oil export terminal, pushing back against weeks of speculation that the facility was in Washington's crosshairs. The denial came as President Trump declared an interim accord to end the Iran war was "over" and warned of new US strikes, while military analysts openly debated whether the Pentagon could — or should — seize Iranian islands in the Persian Gulf. The specific question on the table is whether Kharg Island passes out of Iranian control by March 31, 2026, with the "August 31" outcome the nominal front-runner among a wide field of possible dates. Traders put that outcome at 9%, a figure that has swung sharply over the past week by +4.4 pts even as CENTCOM's denial and the absence of any amphibious operation underscore how far the reality is from the speculation. The resolution standard is exacting: temporary raids, bombardment, naval presence offshore, or sabotage do not qualify — only another state or internationally backed authority establishing primary governmental and military control would trigger a "Yes."

Background

Kharg Island, sitting in the northern Persian Gulf roughly 30 miles off the Iranian coast, handles the overwhelming majority of Iran's crude oil exports, making it a singular strategic asset and a natural target in any confrontation aimed at crippling Tehran's economy. The current escalation traces to Trump's announcement ten days ago that an interim accord to end the war with Iran had collapsed, paired with his warning of fresh American strikes. Against that backdrop, Fox News aired military experts detailing how US Marines could theoretically seize the island in hours — while cautioning that holding it against Iranian missile and drone retaliation would be far riskier. The Middle East Forum separately argued the US should seize Qeshm Island rather than Kharg, and Al Jazeera examined the broader question of whether Washington could take control of Iran's southern islands at all. The market's resolution hinges on sustained control by a foreign authority, not a raid.

The precedent

• During the Iran-Iraq War, Iraq repeatedly bombed Kharg Island's oil facilities, at one point reducing Iran's oil exports from over 6 million barrels per day to roughly 1 million, but never attempted to seize or occupy the island.
• The last time a foreign power established sustained control over Iranian territory was during World War II, when British and Soviet forces jointly occupied Iran from 1941 to 1946.
• The US has not conducted an amphibious assault to seize and hold foreign territory since the Korean War landing at Inchon in 1950.

What to watch

The next inflection point is whether the Trump administration follows through on its warning of new strikes, and whether any operation targets Kharg Island specifically or instead hits other Iranian facilities. CENTCOM's denial that a strike already occurred leaves the island firmly under Iranian control for now. Watch for any amphibious exercises, naval deployments near Kharg, or shifts in Iranian defensive posture around the island — and for whether the interim accord can be revived or is genuinely dead.
