Oil prices edged lower on Friday, heading for a weekly loss of nearly 3% after the IEA forecast a growing glut and US President Donald Trump and Russian President Vladimir Putin agreed to meet again to discuss Ukraine.
Brent crude futures were down 15 cents, or 0.25%, at $60.91 a barrel at 1140 GMT, while US West Texas Intermediate futures were 8 cents lower, down 0.14%, at $57.38.
Trump and Putin agreed on Thursday to another summit on the war in Ukraine, to be held in the next two weeks in Hungary.
The surprise development came as Ukrainian President Volodymyr Zelenskiy was headed to the White House on Friday to push for more military support, including US-made long-range Tomahawk missiles, while Washington pressured India and China to stop buying Russian oil.
"Now that the two leaders are expected to meet, it could be a sign that the US's stance on Russia may ease. If so, that should push prices lower," said Tamas Varga, analyst at PVM.
Ukrainian drone strikes on Russian refineries and the threat of secondary sanctions on buyers of Russian oil such as India and China set a floor under the market, but this could now change, Varga said.
This week's decline was also partly due to rising trade tensions between the US and China, which added to concerns about an economic slowdown and lower energy demand.
"It just demolishes confidence," said Jorge Montepeque, managing director at Onyx Capital Group. He expects the US economy will quickly be impacted.
Also weighing on prices was the International Energy Agency's outlook for a growing supply glut in 2026. The Energy Information Administration said on Thursday that US crude inventories increased by 3.5 million barrels to 423.8 million barrels last week, compared with analysts' expectations in a Reuters poll for a 288,000-barrel rise.
The bigger-than-expected build in crude inventory was largely due to lower refining utilization as refineries go into autumn turnarounds.
The data also showed a rise in US production to 13.636 million barrels per day, the highest on record.
In the previous session, Brent settled 1.37% lower and US WTI closed down 1.39%, their lowest since May 5.
