Oil prices dropped on Tuesday for a second straight session as the cons of a slowing global demand outlook outweighed the pros of OPEC’s agreement with associated producers at the end of last week to deepen crude output cuts in early 2020. U.S. President Donald Trump does not want to implement the next round of tariffs, U.S. Agriculture Secretary Sonny Perdue said on Monday – but he wants “movement” from China to avoid them.”The euphoria (on output cuts) was short lived, with an unexpected fall in exports from China highlighting the impact of the trade conflict,” said ANZ Bank in a note on Tuesday.
