Brent crude rebounded from a 16-month low on speculation cease-fire talks between Russia and Ukraine will ease sanctions against the biggest energy exporter.

Russian President Vladimir Putin outlined a peace plan for Ukraine after agreeing with his Ukrainian counterpart Petro Poroshenko on steps toward a cease-fire in the conflict that has raged for more than five months. West Texas Intermediate rose on expectations supply dropped last week. Oil tumbled yesterday on concern a weakening European economy will curb demand.

"The markets are very much being swayed by the events in Europe and Ukraine," said John Kilduff, a partner at Again Capital LLC, a New York-based hedge fund that focuses on energy. The cease-fire talks "will hopefully stop the downward spiral we are seeing in the euro-zone economy and the worry about more sanctions being applied."
