NEW YORK/TEHRAN/BAGHDAD — The Iran war has cost US consumers an estimated additional $ 100 billion in energy costs, a figure that is rising by roughly 1 million every two minutes, according to a real-time estimate from Brown University as of Monday.

The Iran War Energy Cost Tracker from Brown's Watson School says higher gasoline and diesel prices have cost the average US household more than $760 since the war began on Feb 28.

The US national average price for diesel rose to a record $5.90 per gallon on Monday, surpassing the record $5.85 set on Friday, according to the American Automobile Association.

Texas has borne the biggest share of the cost increase, with consumers paying around $11 billion in extra gas and diesel costs since the war began. It is followed by California and Florida, at about $8 billion and $5 billion, respectively.

US consumers are expecting a longer period of higher fuel prices than they anticipated when the war began, the tracker shows. The rising costs have translated into higher transportation expenses for many everyday goods. Some businesses have already passed those costs on to consumers in the form of additional fees.

Iran says talks with Oman on Hormuz Strait reach final stage

The Iranian Foreign Ministry said on Monday that Iran-Oman negotiations on the designation of a temporary route for safe passage through the Strait of Hormuz have reached their final stage.

The understanding between the two countries regarding the route's designation would likely be registered with the International Maritime Organization in the coming days, ministry spokesman Esmaeil Baghaei said at a weekly press conference in Tehran.

The insecurity in the waterway is a consequence of the US-Israeli "military aggression" against Iran, he said, noting, "Vessels will not be able to travel this route with confidence and a sense of security by the time this situation continues."

Responding to a question about a Sunday visit by a Qatari delegation to Iran, Baghaei said it took place as part of Qatar's efforts to de-escalate tensions in the region.

He said contacts between Iran and certain other regional countries that have long been trying to help reduce tensions "is an ongoing process."

In a joint statement late last month, Iran and Oman announced they had exchanged views on a proposed phased framework that includes establishing a temporary joint shipping corridor in the Strait of Hormuz and an agreement to implement a joint project to demine the waterway.

Technical talks between the two countries will continue to address the designation of a permanent shipping corridor, the future administration of the strait, and a mechanism for information exchange, traffic management, and security arrangements in the waterway, the statement added.

S. Korea warned against Hormuz military involvement

Also on Monday, Baghaei warned South Korea against maintaining a military presence or participating in operations in the Strait of Hormuz.

Baghaei issued the warning in a post on X after Seoul said Friday that it was reviewing options, including military measures, to support "freedom of navigation" in the Strait of Hormuz.

He said that the relationship between Iran and South Korea has a history spanning more than 64 years, and that bilateral ties have consistently developed on the basis of mutual respect, while Iran attaches great importance to its friendly relations with South Korea.

He noted that the Iranian people were currently defending themselves against US "aggressive actions."
