Oil prices turned negative on Tuesday after news of U.S. National Security Advisor John Bolton’s firing gave rise to speculation that Washington was getting rid of its chief hawk on Iran to make a deal with Tehran.
- President Donald Trump said in a tweet that he had asked for Bolton’s resignation, adding that he “disagreed strongly with many of (Bolton's) suggestions, as did others in the (a)dministration.”
- West Texas Intermediate crude, the U.S. benchmark blend, was down 12 cents, or 0.2%, at $57.73 per barrel by 12:48 PM ET (16:48 GMT), hitting a six-week high of $58.76.
