As US sanctions on Iran tighten and gas prices reach record levels, it is becoming more likely that a release of oil from the US Strategic Petroleum Reserve is in the works.

Administration officials said Friday that reserves from the SPR were taken into account when they determined that oil markets could handle the loss of Iranian oil. Even before the tighter sanctions were announced, there was talk the administration had been colluding with European countries on a coordinated withdrawal. The rumors have already pushed global oil prices down slightly, although they remain over $120 a barrel.
