Oil markets are trapped in a Trump-driven guessing game, with Iran fears lifting prices one moment and calming signals pulling them back the next. Will Donald Trump attack Iran again or not? That has been the multi-billion-dollar question of this week, with the initial price rally seeming to suggest an emphatic ‘yes’, only for Trump to pour cold water on the war hysteria by claiming there’s no executions in Iran. With news on Venezuela lacking real market impact lately, ICE Brent’s seesawing around the $65 per barrel could very well continue into next week, as market participants guess the US President’s next move.
