Oil prices rose about 1% to three-year highs on Jan. 11, pushing the global Brent benchmark past $70 a barrel (bbl), on further signs of tightening supply in the U.S. and expectations that OPEC's output cuts would underpin the market.
Brent crude surged to $70.05/bbl, its highest since November 2014. As of 11:54 a.m. CST (17:54 GMT), the contract was trading 56 cents, or 0.8%, higher at $69.76. Brent has gained 5% since the beginning of the year, picking up from its late-year surge.
U.S. West Texas Intermediate crude futures rose 86 cents, or 1.4%, to $64.43, the highest since December 2014.
"[U.S.] crude oil inventories are at their lowest level since August 2015," said PVM Oil Associates analyst Tamas Varga. "OPEC is edging ever closer to its desired target of reducing OECD industrial stocks to the five-year average."
On Jan. 10, the U.S. Energy Information Administration said crude inventories fell almost 5 million bbl to 419.5 million bbl last week. Production slowed by nearly 300,000 bbl/d, which analysts attributed to colder-than-usual weather across the U.S. last week.
Adding to bullish sentiment on Jan. 11, market intelligence firm Genscape estimated a draw of more than 3.5 million bbl at the Cushing, Okla., delivery point for U.S. crude futures for the week ended Jan. 9, according to traders who saw the data.
"The steady, if not rapid, decline in U.S. crude oil inventories from persistently high refinery demand and elevated exports has firmly registered with the market," said John Kilduff, partner at Again Capital LLC in New York.
Production cuts led by OPEC and Russia, which are set to continue throughout 2018, have underpinned prices.
The United Arab Emirates Energy Minister and OPEC President Suhail al-Mazrouei said he expects the market to balance in 2018 and that the producer group is committed to its supply-reduction pact until the end of this year.
The greenback-denominated commodity has also benefited from weakness in the dollar, which neared a one-week low on Jan. 11, as it makes oil cheaper to buy for holders of other currencies.
Trading volumes were higher than average, with a flurry of deals at about 9 a.m. CST as prices jumped. More than 566,000 U.S. crude contracts had changed hands on Jan. 11 as of 11:10 p.m., not far from the daily average of 619,000 contracts over the past 200 days of trading.
Brent may not be able to sustain a $70 level unless additional news from the Middle East bolstered bullish sentiment, analysts said.
ICE Commitment of Traders figures showed speculators raised their net long holdings of Brent crude futures and options in the week to Jan. 2 to a new record. Heavy bets like this are at risk of being unwound after quick gains.
"You have a very overbought market. Oil is acting like an Internet stock and when it does that you know it’s getting overcooked," said Walter Zimmerman, chief technical analyst for United-ICAP.
