Oil prices rise nearly 2% on fresh attacks by US and Iran

Oil prices gained nearly 2% on Tuesday on fresh attacks exchanged by the U.S. ‌and Iran as well as threats of a naval blockade of Saudi Arabia by Yemen's Houthis, Reuters reported.

Brent crude futures rose $1.62, or 1.8%, to $90.84 a barrel by 1152 GMT.

The front-month U.S. West Texas Intermediate crude contract , which expires on Tuesday, was up $1.37, or 1.7%, at $84.60. The more active contract for September delivery rose $1.48, or 1.8%, to $83.96.

"Lower exports through the Strait of Hormuz and concerns of potential supply disruption from oil ⁠coming through the Red Sea are moderately supporting oil prices," said UBS analyst Giovanni Staunovo.

U.S. forces bombed targets in southern Iran overnight after President Donald Trump said that Tehran would pay dearly for the deaths of American soldiers. Iran, meanwhile, targeted U.S. sites in Bahrain, Kuwait and Jordan.

A tanker in the Strait of Hormuz reported being struck by an unknown projectile, forcing its crew to abandon ship and board a lifeboat, the United Kingdom Maritime Trade Operations agency said on Tuesday as vessel crossings dropped further.

The optimist may see the latest American attacks as a last attempt to strengthen the negotiating position before a compromise is reached and the Strait of Hormuz ‌is reopened," ⁠an SEB Research note said.

However, the risk is a more prolonged stalemate, with continued uncertain energy flows, higher oil prices and recurring attacks."

Limiting price gains, a senior Iranian official told Reuters that Tehran had received a proposal from mediators for a 10-day ceasefire in efforts to salvage the deal signed on June 17, intended to pave the way for a ⁠lasting agreement to end the war that began on February 28 with U.S.-Israeli attacks on Iran.
