Exposure of world’s reliance on Middle East supplies accelerates global shift towards new energy superpowers

n the open seas, an armada of empty tankers has quietly turned west. A record number of super-sized vessels are now heading to the US, where oil drillers and refineries are preparing to profit from Donald Trump’s war in the Middle East.

Almost 30 of these vessels, each able to hold 2m barrels of oil, are contracted to load US crude, destined for a global market facing the biggest supply crisis in history.

It is just over five years since the shale revolution made the US a net energy exporter and the world’s biggest producer of oil and gas. Now the White House is poised to strengthen its claim to an even greater share of the global oil market as the Middle East’s decades-long dominance is dismantled by war.
