Crude oil prices advanced on Monday after U.S. President Donald Trump threatened renewed military action against Iran, casting doubt on the durability of a fragile interim peace agreement reached just last week.
The remarks from the White House have reignited concerns among market participants that the diplomatic progress made in recent days may be short-lived, potentially exposing key energy transit routes to renewed conflict.
Brent crude futures climbed in the session as traders repriced the probability of a supply disruption in the Strait of Hormuz.
The move reflects persistent anxiety over regional stability, with investors wary that any escalation could choke off a significant portion of global seaborne oil flows.
WTI crude also posted gains, tracking the broader risk premium attached to Middle Eastern tensions.
The latest threat from Trump comes amid a volatile backdrop for U.S.-Iran relations.
