Prices plunged shortly after the announcement of the departure of Mr. Bolton, around 12 pm, before stabilizing at the end of the session
Tuesday, September 10, 2019 ((rezonodwes.com)) – Oil prices , which were on the rise, erased their gains on Tuesday after Donald Trump announced the dismissal of National Security Advisor John Bolton.
Brent North Sea crude for November delivery was $ 62.38 in London, down 0.3% (or 21 cents) from Monday's close.  In New York, WTI's US barrel for October delivery ended at $ 57.40, 0.8% (or 45 cents) less than the day before.
“ I informed John Bolton last night that we no longer needed his services at the White House “, tweeted Mr. Trump, barely an hour after the announcement by the executive of a press briefing attended by Mr. Bolton with Secretary of State Mike Pompeo
In a terse and enigmatic tweet, Mr. Bolton indicated that he had offered to resign Monday night and that the President had replied: “ Let's talk about it tomorrow “
This spectacular dismissal takes place in a particularly tense climate between the United States and Iran, a case on which Donald Trump has sent contradictory signals in recent weeks, between extreme firmness and willingness to negotiate.
“ John Bolton was holding a hard line against Iran and was pressuring for more sanctions against Tehran “said Matt Smith of ClipperData.
