What effect will President Trump have on Opec, the Middle East and world oil markets?

Given that he has annunciated strikingly few clear policy proposals and that Congress, even a Republican controlled one, is likely to water down his wackier schemes, it is difficult to say.

His election is bullish for US production, notwithstanding that the main factor governing whether to invest is the oil price, not policy. US E&P firms saw their share prices rise, albeit modestly, post-election.
