Meanwhile, West Texas Intermediate crude oil was down by 22 cents, or 0.38 per cent, to Dollars 57.14, while Brent fell 23 cents, or 0.36 per cent, to trade at USD 63.17 a barrel.

However, some uncertainty remains over the reliability of this commitment as well as over how suddenly the group will increase output once the voluntary restraint ends. The oil minister said OPEC could end the cuts early if the market rebalances and noted that Russian Federation is especially keen to pump more. The UAE holds OPEC presidency in 2018.
