Oil rose on Wednesday as President Donald Trump reimposed a naval blockade on all Iranian ports and Iran launched retaliatory strikes on U.S. infrastructure in the ​region.

For the second straight session, Brent closed at its highest since June 12 ‌and West Texas Intermediate at its highest since June 15 and rose further on early Wednesday trade.

Brent rose $1.46, or 1.72%, to $86.19 a barrel by 0029 GMT while WTI was up $1.11, or 1.4%, to $80.40 a ​barrel.

Oil prices closed up 2% to a one-month high on Tuesday as attacks ​deepened a supply disruption in the Strait of Hormuz, where some one-fifth ⁠of the world’s oil and liquefied natural gas transited prior to the beginning of the ​war.

Early on Wednesday, the U.S. also began a fresh round of strikes "to continue degrading Iranian capabilities ​used to attack commercial shipping in the Strait of Hormuz," the U.S. military said.

Tehran says it has again closed the strait after hostilities between Iran and the U.S. reignited last week, fraying an already ​fragile truce reached in June after several months of fighting.

"I'll save the energy targets for ​last, but ultimately we'll hit energy targets," Trump told Fox News in an interview aired Tuesday night ‌on "Special ⁠Report with Bret Baier".

Iran's army said early on Wednesday that it had launched drone attacks against U.S. positions at Jordan's Azraq base. There was no immediate comment from the Pentagon.

Iran's Islamic Revolutionary Guard Corps said they targeted weapons and storage facilities in Bahrain and Kuwait. ​Reuters could not immediately ​verify the reports.

The flare-up ⁠over the last few days has heightened doubts that a memorandum of understanding signed last month would lead to a permanent halt ​to the war, which has engulfed Iran's neighbors.

“The chances of oil ​moving back ⁠toward $100 in the reasonably near term are still meaningful if hostilities intensify which damages energy infrastructure around the Gulf,” Tim Waterer, chief market analyst at KCM Trade said, noting Brent prices ⁠could remain ​at $75-$80 a barrel if diplomatic efforts helped reopen the ​strait.

“For now, the risk premium is still embedded, but it’s not a one-way bet given that there remain incentives ​for both sides to find a diplomatic solution.”
