Brent crude rose nearly 2% after hitting a four-year high on Wednesday as the market focused on upcoming U.S. sanctions on Iran while shrugging off the year’s largest weekly build in U.S. crude stockpiles and reports of higher Saudi Arabian and Russian production.
Brent crude breached US$ 81 a barrel on Monday — its highest level in nearly four years — on the back of a tightening oil market and OPEC leaders signaling they won't be immediately boosting output. Global benchmark Brent crude rose as high as US$ 81.39 a barrel, its strongest level since Nov. 21, 2014.
