OPEC and allied producers, including Russia, agreed to cut oil output by a deeper-than-expected amount after two days of meetings. The decision responded to a glut that had pushed crude prices down roughly a third since early October.
A coordinated supply cut tightens crude balances and tends to lift energy prices, which feeds into biofuel margins and feed input costs.
