Petroleum prices fell for a second day on Wednesday on the potential of Iranian supply returning and as investors sold on speculation that inflation fears might lead the U.S. Federal Reserve to raise interest rates, which could limit economic growth.
U.S. West Texas Intermediate (WTI) crude futures fell $1.07, to 1.6%, to $64.42 per barrel, following a 1.2% fall on Tuesday.
Brent crude futures dipped $1.10, or 1.6%, to $67.61 per barrel, after dropping 1.1% on Tuesday.
Officials said speculation that the Federal Reserve might raise rates because of inflation fears weighed on the outlook for growth and in turn on commodities demand.
The Fed has indicated that interest rates will stay at their current low levels through 2023 though futures markets show investors believe rates may start to be raised by September 2022.
Oil prices were also under pressure amid reported progress on talks between the United States and Iran to revive a deal limiting its nuclear program, which could lead to a lifting of sanctions and a resurgence of Iranian oil exports.
Investors will be watching out for the latest U.S. crude and products stocks data from the U.S. Energy Information Administration due on Wednesday.
Data from the American Petroleum Institute on Tuesday showed crude inventories rose by 620,000 barrels in the week ended May 14, while gasoline inventories fell by 2.8 million barrels and distillate stocks fell by 2.6 million barrels.
