U.S. crude will likely be the biggest beneficiary from the shutdown, with Europe buying U.S. shale oil to replace lost Libyan supply, Smith said.
Israel launched a major wave of airstrikes in Lebanon on Sunday, describing the operation as a preemptive strike to prevent Hezbollah from firing a barrage of missiles. Hezbollah said it had launched hundreds of missiles at Israel in retaliation for the killing of one of the militia's senior commanders in July.
The Middle East has been on edge for weeks after the assassinations of the Hezbollah commander in Beirut and a Hamas leader in Tehran, Iran.
Iran has also vowed to retaliate against Israel, but so far the threatened attack has not materialized.
