HOUSTON (Reuters) - The Brent and US West Texas Intermediate crude oil benchmarks rose more than $1 a barrel on Friday as markets watched for a possible direct military conflict between Israel and Iran that could further tighten supplies.
Brent crude was up $1.00, or 1.1%, to $91.65 a barrel by 11:44 a.m. CDT (1644 GMT). US West Texas Intermediate crude was at $87.41 a barrel, up 81 cents, or 0.95%.
Both benchmarks settled on Thursday at their highest levels since October.
Brent and WTI are set to notch more than 4% gains this week after Iran, the third-largest OPEC producer, vowed revenge against Israel for an attack that killed high-ranking Iranian military personnel.
"If Iran directly attacks Israel, that's never happened before," said Phil Flynn, an analyst at Price Futures Group. "It's just another geopolitical risk domino about to fall."
Israel has not claimed responsibility for the attack on Iran's embassy compound in Syria on Monday.
Ongoing Ukrainian drone attacks on refineries in Russia may have disrupted more than 15% of Russian capacity, a NATO official said on Thursday, hitting the country's fuel output.
The Organization of the Petroleum Exporting Countries (OPEC) and allies led by Russia, known as OPEC+, this week kept its oil supply policy unchanged and pressed some countries to increase compliance with output cuts.
"Further clampdowns on adherence to quotas should see output fall further in Q2," ANZ analysts Daniel Hynes and Soni Kumari wrote in a note.
This is the future home of the Rixos Baghdad, a luxury hotel financed by Qatar in the city's heavily fortified Green Zone.
"The prospect of a tighter market should see a drawdown in inventories during the second quarter."
Meanwhile, US job growth soared in March, easily beating expectations, according to official data released on Friday which also showed a steady increase in wages.
The gain of 303,000 jobs last month points to likely robust oil demand but potentially delays anticipated interest rate cuts by the US Federal Reserve later this year.
Global oil demand is expected to grow by 1.4 million barrels per day (bpd) in the first quarter, JPMorgan analysts wrote in a note.
"Our high-frequency demand indicators estimate that total oil consumption in March averaged 101.2 million bpd, 100,000 bpd above our published estimates," they said.
