The opening losses came after a drone strike caused a fire at a nuclear power plant in the United Arab Emirates, while Saudi Arabia reported intercepting three drones, as US President Donald Trump warned that Iran must act “fast” to reach a deal.
Meanwhile, the vital Strait of Hormuz remains closed to all but a trickle of shipping as Tehran tries to formalise its control of the waterway that used to carry 20 percent of the world’s oil trade.
“The closure is draining global oil inventories fast,” warned analysts at Capital Economics.
“Inventories could reach critical levels by end-June, setting the stage for Brent at US$130-US$140 per barrel, if not higher.”
“If the strait is closed through year-end and oil stays around US$150 per barrel into 2027, that would push inflation to near 10 percent in the UK and euro zone, send rates back to their recent peaks and lead to global recession.” (Reuters/Xinhua)
