US, Iranian Forces Exchange Fire Near Iran Raising Oil Supply Concerns

Escalation of Military Tensions and Impact on Oil Markets

Exchange of Fire in the Strait of Hormuz

DUBAI, Sept 5 (Reuters) - U.S. and Iranian forces fired at vessels in waters around Iran on Saturday, including three Iranian oil carriers struck by the Americans and three tankers that Iran said it targeted while on unauthorized routes in the Strait of Hormuz.

U.S. Central Command said it struck the three Iranian vessels, including one off the coast of Kharg Island, near Iran's oil export hub, after Iran's Islamic Revolutionary Guard Corps launched ballistic missiles at two U.S. Navy ships.  

US Military Response

“Let the message to the IRGC be clear: If you shoot at two of our ships, we will impose an even higher economic cost — taking out three of yours," said Admiral Brad Cooper, head of U.S. Central Command, which oversees the U.S. military in the Middle East.

Iranian Counteractions

The IRGC responded by threatening intensified strikes against U.S. military vessels in the region, and said later it targeted the three tankers as well as three U.S.-linked vessels in other areas. 

"Do not be deceived by the 'terrorist' U.S. military and refrain from any suspicious movement aimed at passing through unauthorized waterways," the IRGC Navy said in a statement carried on Iranian state TV. "Otherwise, you will be targeted."

Reports from Iranian Media

Tasnim, the semi-official Iranian news agency, had reported that four U.S. missiles hit a tanker in the area of Kharg's anchorage. Tasnim quoted local sources as saying there were no casualties and the tanker's crew was being evacuated.

No American personnel were harmed, Central Command said. 

Broader Context: Ongoing Conflict and Oil Supply Risks

The exchange of attacks followed an escalation in the past week that threatens to deepen a conflict that has continued since the U.S. and Israel launched strikes on Iran in February, disrupting global energy supplies and drawing opposition from a majority of Americans before congressional elections in November. 

Trump's Threats Over Kharg Island

TRUMP'S THREATS OVER KHARG ISLAND 

While U.S. President Donald Trump's administration seeks to pivot toward an economic clampdown on Iran by widening sanctions, the president himself has kept open the possibility of military action.

Social Media and Political Rhetoric

On August 31, Trump issued a one-line social media post accompanied by an AI-generated video depicting Kharg Island being "blown to smithereens." Iranian authorities have vowed a strong response if Kharg is attacked.

Strategic Importance of Kharg Island

Iran is the third-largest producer in the Organization of the Petroleum Exporting Countries and exported 90% of its crude via Kharg Island before the war. Flows have been disrupted since a U.S. blockade of Iranian oil exports began in mid-April.

Trump has spoken of an attack on Kharg before. He said on June 11 that he wanted to take over the island, but then said a U.S. ​military operation there was off the table, days before Tehran and Washington signed an interim agreement aimed at ending the war on June 17.

Oil Market Reactions and Economic Impact

A U.S. attack on Kharg would further pressure Iran's oil industry and its wider economy, which is already reeling from the U.S. naval blockade.

The U.S. imposed its blockade on Iranian ports after Iran effectively shut the Strait of Hormuz, an important waterway that carried one-fifth of the world's oil supply before the war.

Brent crude futures closed at their highest level since July 24 on Friday, at $96.28 a barrel, as tensions in the Middle East drive global supply concerns.
