WTI crude opened slightly higher as the US and Iran remain at odds over how to reopen the Strait of Hormuz. President Trump said he was "not satisfied" with the talks. The White House denied an Iranian report that a draft agreement would have Iran and Oman oversee shipping through the strait. Despite the difficulties, oil prices remain on track to slip for a second straight week amid optimism that the two sides could at least reach a temporary deal. The protracted negotiations hinge on Iran's desire to retain control over the Strait of Hormuz and the fate of its nuclear program.
