The US Treasury Department has revoked a waiver that had allowed the sale of Iranian oil, according to Bloomberg Markets, after new attacks on tankers in the Strait of Hormuz. The move sharpens sanctions pressure at a time when security risks in the strait are already under close watch across crude and product shipping markets.
For tanker flows, the decision matters because Hormuz remains a critical chokepoint for Gulf exports. Any tighter enforcement on Iranian barrels, combined with renewed attacks on commercial shipping, can raise voyage risk, complicate routing and insurance, and add volatility to regional freight and loadings.
