Oil prices rose on Friday and settled with their biggest weekly gains in over a year on the mounting threat of a region-wide war in the Middle East, although gains were limited as U.S. President Joe Biden discouraged Israel from targeting Iranian oil facilities.

Iran and Libya are both members of OPEC. Iran, which is operating under U.S. sanctions, produced about 4.0 million barrels per day of fuel in 2023, while Libya produced about 1.3 million bpd last year, according to data from the U.S. Energy Information Administration.
