Brent hits one-month high over concerns about prolonged Hormuz disruption

Oil prices rose nearly 3% on Wednesday, ‌with the Brent contract hitting a one-month high, on media reports the U.S. will extend its blockade of Iranian ports, likely prolonging supply disruptions from the key Middle East producing region.

U.S. President Donald Trump has instructed aides to prepare for an extended ​blockade of Iran, the Wall Street Journal reported late on Tuesday, citing U.S. officials.

Trump will opt ​to continue to squeeze Iran's economy and oil exports by preventing shipping to and from ⁠its ports, the report said. Despite a ceasefire in the U.S.-Israeli war with Iran, the conflict is deadlocked as both ​sides seek a formal end to the fighting.

Brent crude futures for June rose $3.08, or 2.8%, to $114.34 a barrel ​at 0824GMT, climbing for an eighth day to the highest since March 31. The June contract expires on Thursday and the more active July contract was at $107.08, up 2.6%.

U.S. West Texas Intermediate (WTI) futures for June CLc1 rose $2.75, or 2.8%, to $102.68 a barrel, the ​highest since April 13. The contract has risen for seven out of the last eight days.

"The recent rise ​in oil prices has been driven by the Strait blockade. If Trump is prepared to extend the blockade, supply disruptions would ‌worsen ⁠further and continue to push oil prices higher," said Yang An, an analyst at Haitong Futures.

Investors were also assessing the ramifications of the United Arab Emirates' surprise decision to quit OPEC.
Analysts did not expect any major near-term impact on the market by the move.

"The United Arab Emirates’ exit from OPEC+ formalises the organisation's weaker cohesion, but the ​near‑term impact is limited," said ​an ANZ Research note. "The ⁠move reflects long‑standing quota tensions, but prices are still being driven more by geopolitics, inventories and logistics than by institutional changes."

There must be a resolution in the ​Persian Gulf that allows for uninhibited energy flows through the Strait of Hormuz once ​again before the ⁠UAE's output increase can come into effect, ING analysts wrote in a note on Wednesday.

In the medium to longer term the UAE's decision means more supply for the market, which suggests that the Brent forward curve should move ⁠into deeper ​backwardation, ING analysts said.

Market participants awaited data from the U.S. Energy ​Information Administration on stockpiles. The American Petroleum Institute reported on Tuesday domestic crude oil inventories fell for a second week.
