Oil prices rose more than 1 percent on Friday after the US Navy destroyed an Iranian drone in the Strait of Hormuz, a major chokepoint for global crude flows, again raising tensions in the Middle East.
Brent crude futures were up 82 cents, or 1.3 percent, at $62.75 by 0100 GMT. They closed down 2.7 percent on Thursday, falling for a fourth day.
West Texas Intermediate crude futures firmed 61 cents, or 1.1 percent, at 55.91. They fell 2.6 percent in the previous session.
The United States said on Thursday that a US Navy ship had "destroyed" an Iranian drone in the Strait of Hormuz after the aircraft threatened the vessel, but Iran said it had no information about losing a drone.
The move comes after Britain pledged to defend its shipping interests in the region, while US Central Command chief General Kenneth McKenzie said the United States would work "aggressively" to enable free passage after recent attacks on oil tankers in the Gulf.
Still, the longer-term outlook for oil has grown increasingly bearish.
The International Energy Agency (IEA) is reducing its 2019 oil demand forecast due to a slowing global economy amid a US-China trade spat, its executive director said on Thursday.
The IEA is revising its 2019 global oil demand growth forecast to 1.1 million barrels per day (bpd) and may cut it again if the global economy and especially China shows further weakness, Fatih Birol said.
"China is experiencing its slowest economic growth in the last three decades, so are some of the advanced economies ... if the global economy performs even poorer than we assume, then we may even look at our numbers once again in the next months to come," Birol told Reuters in an interview.
Last year, the IEA predicted that 2019 oil demand would grow by 1.5 million bpd but had already cut the growth forecast to 1.2 million bpd in June this year.
Speculators have exited options positions that could have provided exposure to higher prices in the next several years, market participants said on Thursday.
