Benchmark Brent oil settled at below $62 a barrel and U.S. crude slumped to under $58 to extend Thursday’s landmark fall below $60.
Surging crude inventories in the United States and top oil exporter Saudi Arabia’s reiteration that it will not cut production had roiled prices over the last two days despite data pointing to strong U.S. economic recovery.
On Friday, the Paris-based International Energy Agency which coordinates the energy policies of industrialised countries, cut its outlook for demand growth in 2015, triggering another collapse.
The IEA slashed its outlook for global oil demand growth for 2015 by 230,000 barrels per day to 900,000 bpd on expectations of lower fuel consumption in Russia and other oil-exporting countries.
It predicted that oil-producing nations outside of the Organization of the Petroleum Exporting Countries will add to global supplies. It also expected prices to fall further.
“That’s just more bad news for the oil markets,” said Andrew Lipow, president of Houston-based Lipow Oil Associates.
Brent settled down $1.83, or nearly 3 percent, at $61.85 per barrel. It fell to $61.35 during the session, the lowest since July 2009.
U.S. crude finished down $2.14, or 3.6 percent, at $57.81. It fell earlier to $57.34, its lowest since May 2009.
On the week, Brent lost more than $7, or about 11 percent. U.S. crude tumbled over $8, or 12 percent.
Both markets have lost about 46 percent of their value since their June highs, when Brent stood at above $115 and U.S. crude at around $107.
The IEA outlook had a greater impact on Friday’s market than data from U.S. oil services firm Baker Hughes showing the number of rigs drilling for oil in the United States were down by 29 this week, the biggest weekly drop in two years.
Voluminous crude from U.S. shale projects has been blamed for much of the global oil glut now, and energy traders have been watching rig data to see if prices that have almost halved since June will prompt a cutback in drilling.
Regulators in North Dakota, one of the largest shale oil producing states in the United States, also said on Friday the state’s crude production held steady in October despite strict new rules that aim to prevent wasteful burning of natural gas produced alongside oil.
