US Taps Final SPR Tranche as Diesel Tops $6 Amid Iran War

The US DOE will offer 40 million barrels from the SPR via exchange, the last tranche of the 172 million barrels pledged to the IEA-coordinated release. SPR stocks fell to 286.6 million barrels by end-August, the lowest in decades, as the Iran war keeps fuel prices elevated. This signals sustained supply tightness and limited US strategic buffer, raising concerns about future emergency response capacity.
