DONALD Trump and global crude producers are set to take prices on a bumpy ride this year, according to the world's biggest independent oil trader.

As investors are kept on tenterhooks over US policies and whether the Organization of the Petroleum Exporting Countries (Opec) and other nations will curb output as pledged, global benchmark Brent crude may vacillate between US$52 and US$62 a barrel, according to Kho Hui Meng, the head of the Asian arm of Vitol Group.
