A glut has been building since OPEC+, led by Saudi Arabia and Russia, failed to renew output cuts last month. OPEC+ agreed new curbs this month, but government lockdowns to contain the pandemic have cut fuel demand more steeply.
Brent crude LCOc1, which fell 24% in the previous session, touched $15.98 a barrel, its lowest since June 1999. It was trading down $1.83, or 9.5%, at $17.50 by 0840 GMT.
U.S. West Texas Intermediate CLc1 was down 15 cents, or 1.3%, at $11.42.
“Be prepared for more surprises in this broken oil market,” said Rystad Energy’s head of oil markets, Bjornar Tonhaugen, adding that prices could sink to unprecedented levels because there will simply not be enough storage capacity unless there are further outputs cuts.
The falls follow two of the wildest days in the history of oil trading, with supply looking likely to outstrip demand for months to come.
The nearby U.S. contract fell into negative territory for the first time ever on Monday and Brent’s low on Wednesday takes the price back to a time when OPEC was also tackling a supply glut and business and consumers were concerned about the Millenium Bug affecting computers after the turn of the century.
In the latest sign of excess supply, the American Petroleum Institute on Tuesday reported that U.S. crude inventories rose by 13.2 million barrels, against analyst expectations for an increase of 13.1 million barrels.
The U.S. government’s official supply report is due later on Wednesday.
In an effort to shore up the market, OPEC+ this month agreed to reduce output by 9.7 million bpd. Other nations, including the United States, have also said they will pump less.
