But whether prices can maintain levels at $70 or above is dependent on the willingness of Russia to keep backing a Saudi Arabia-led effort to cut production in the face of growing US shale supply. Other participants in the co-ordinated effort also need to sustain strong compliance with the deal, the incentive of which declines as governments reap the rewards of higher prices.
