Oil markets are bracing for a possible supply shock after U.S. strikes on Iran over the weekend reignited fears that flows through the Strait of Hormuz could be disrupted.

While analysts expect an immediate “knee-jerk” reaction to oil prices when trading resumes in New York on Sunday evening, the bigger question is whether tensions could escalate into a sustained interruption of Gulf exports. “At this point, it seems we are looking at a full-scale military conflict between the U.S. and Iran, which would be unprecedented and the trajectory impossible to assess,” said Vandana Hari, CEO of energy research firm Vanda Insights.

“If it carries on for days with Iran and its proxies retaliating to the fullest extent, we are looking at the worst-case scenarios for oil, including a major disruption of oil flows through the Middle East,” Hari told CNBC. This is unless the U.S. is able to pre-emptively disarm the Iranian navy and military, as well as ensure tanker traffic through the Strait of Hormuz continues to flow normally.

With tensions escalating, attention has shifted back to the Strait of Hormuz, where any disruption would have immediate and outsized consequences for global oil and LNG flows.
