Mrs Dong thinks that crude oil supply is the key factor for its future price. This supply is from exhausting output of traditional oil fields, alternative shale oil and remaining capacity of OPEC. She delivers that in testing shale oil growth, output growth of China and Mexico falls faster in 2016 and Russia and oil producing countries of North Sea will see the similar situation next year. During the period, shale oil supply growth from decrease to increase will test oil price. For OPEC, it has already gained victory in market share scramble with non-OPEC and future balance depends on interior of the organization’s willingness of regaining oil pricing right or not. As for the crude oil price, she thinks that it may sustain range bound at the bottom and seasonal discipline continues to take effect.
