Crude futures edged lower on Tuesday as traders weighed mercurial US-Iran peace talks against escalating threats to major global maritime oil chokepoints.
Brent futures contract eased over 1% to $93.91 per barrel. Murban futures closed at $94.43 on June 1 and were not trading by the time of publication of this oil price update.
The slight pullback reflects a cautious wait-and-see approach from investors after US President Donald Trump said on social media "it will all work out well in the end."
However, the underlying market sentiment remains deeply grim. Iran reportedly said on Monday that it was suspending indirect negotiations with Washington in protest of continued military actions in Lebanon.
Compounding the diplomatic gridlock, Iranian state media reported that Tehran is now aiming for a complete blockade of the critical Strait of Hormuz.
The threat to global oil flows is expanding beyond Hormuz. Iran's proxy militant groups are reportedly considering closing the Bab el-Mandeb Strait at the southern end of the Red Sea.
This development is particularly alarming for energy markets, as the Bab el-Mandeb has served as the vital alternative route for Saudi Arabian exports to bypass the already-closed Strait of Hormuz.
TPH analysts said the uranium provision is likely to face strong resistance from Tehran, potentially complicating negotiations already strained by what Iran has described as shifting US positions.
