Crude oil traded around $82.5 a barrel on Monday, maintaining last week’s advance as investors weighed the risk of further supply disruption from escalating Middle East tensions. Israel carried out new strikes on Lebanon over the weekend that killed 11 people, including a senior Hezbollah commander, while President Donald Trump prepared new economic sanctions intended to force Iran to surrender. The interim ceasefire agreement between the U.S. and Iran was due to formally expire later in the day, and negotiations to end the conflict and reopen the Strait of Hormuz remained stalled. At the same time, Middle Eastern producers were covertly moving millions of barrels of crude through the waterway, a flow that helped cap additional price gains despite the geopolitical premium.
