Oil rose

West Texas Intermediate crude rebounded from the lowest close in almost three weeks as the U.S. said it will toughen sanctions on Russia, the biggest energy exporter, over the Ukraine crisis. Brent was steady as Libya lifted force majeure at one of its ports.

Futures advanced as much as 0.9 percent in New York. The U.S. will impose new sanctions today on people and companies close to Russian leader Vladimir Putin, President Barack Obama said. Among those that may be targeted are Igor Sechin, chief executive officer of OAO Rosneft, the country’s biggest oil producer, people familiar with developments said. Libya’s National Oil Corp. will lift a suspension of exports at the port of Zueitina, previously under rebel control, from today.

“The price is being supported by uncertainty as to the breadth and impact of sanctions taken against Russia,” Christopher Bellew, a senior broker at Jefferies Bache Ltd. in London, said by e-mail. “Another important consideration is how Russia might retaliate against sanctions.”
