WTI steady near one-month-highs after API reports big crude draw

Oil prices ended the day marginally down from one-month-highs, amid some notable swings intraday, after Libya recently restarted production at its largest oil field.

The pullback in prices came "in conjunction with no new developments in the Red Sea and the opening of Libya's largest oil field," said Rania Gule, market analyst at XS.com.
