Brent fell below $65 for the first time in more than five years as OPEC cut the demand forecast for its crude oil to a 12-year low. West Texas Intermediate dropped near $60 as U.S. inventories grew.
Both benchmarks are more than 40 percent below their 2014 peaks in June. OPEC reduced its projection for 2015 by about 300,000 barrels a day to 28.9 million in its monthly report today. U.S. crude inventories rose to the highest seasonal level in weekly data that started in 1982, the Energy Information Administration said.
Brent has collapsed 17 percent since Nov. 26, the day before OPEC agreed to leave its production limit unchanged at 30 million barrels a day, resisting calls from members including Venezuela to cut output to stabilize prices. The decision prompted the biggest one-day decline in more than three years.
