Treasury Secretary Scott Bessent said the 30-day authorization could allow around 140 million barrels of Iranian oil to reach global buyers. The US Treasury Department described the measure as a “narrowly tailored, short-term authorization” that applies only to oil already loaded onto tankers, not new shipments. The waiver remain will remain in effect until April 19. US officials said other sanctions remain in place, including restrictions intended to limit Iran’s access to any revenue generated by the sales. The step comes as Washington seeks to contain the impact of surging oil prices linked to turmoil in the region.
