NEW YORK: Oil prices rose about 3pc on Wednesday and hit their highest in about a month, buoyed by US government data that showed a much larger-than-expected drawdown in US crude inventories as exports hit a record high, and surprise drops in refined product stockpiles.
Brent crude futures rose $1.61, or 2.5pc, to $66.66 a barrel by 11:06 a.m. EDT (1506 GMT). US West Texas Intermediate (WTI) crude futures rose $1.84, or 3.2pc, to $59.67 a barrel.
Crude inventories fell 12.8 million barrels last week, the Energy Information Administration said, far surpassing analyst expectations for a decrease of 2.5 million barrels. That was the most since September 2016, according to the statistical arm of the Department of Energy.
Net US crude imports fell last week by 1.2 million barrels per day. Overall crude exports rose to 3.8 million bpd, beating its previous record of 3.6 million bpd in February.
"A lot of this drawdown is due to strong demand," said Phil Flynn, an analyst at Price Futures Group in Chicago. "We're finally seeing the impact of OPEC production cuts and starting to see Venezuelan cuts."
Gasoline stocks fell by 996,000 barrels, while distillate stockpiles fell by 2.4 million barrels, the EIA data showed.
The product drawdown comes at the same time as news that the largest and oldest refinery on the US East Coast will be permanently shut after a massive fire last week caused substantial damage.
Philadelphia Energy Solutions plans to shut down the 335,000 bpd refinery complex next month, Philadelphia mayor confirmed after two sources told Reuters about the plans.
US gasoline futures were up 4pc after climbing to their highest since May 23 in overnight trade.
"Refinery margins are improving globally because if that refinery can't operate then you'll have to compensate with higher runs elsewhere," Olivier Jakob of Petromatrix consultancy in Switzerland said.
The crude inventory fall and refinery outage added to uncertainty over oil supplies created by the war of words between Washington and Tehran. This has prompted fears that oil shipments through the Strait of Hormuz - the world's busiest oil supply route - could be disrupted.
Asked if a war was brewing, US President Donald Trump told Fox Business Network on Wednesday: "I hope we don't but we're in a very strong position if something should happen." Tehran has condemned a fresh round of US sanctions as "mentally retarded."
Bilateral tensions spiked anew after Iran shot down a US drone last week in the Gulf. Relations have been tense since Washington blamed attacks on oil tankers just outside the Gulf on Iran, while Tehran has denied any role.
In the search for longer term direction, markets will watch the G20 meeting this weekend followed by a meeting of the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC producers, a group known as OPEC+, taking place on July 1-2.
The group is due to discuss extending output cuts for the second half of this year.
Russia's average oil output was 11.15 million barrels per day (bpd) in the period June 1-25, up from an average of 11.04 million bpd during June 1-10, two sources familiar with official data said on Wednesday.
