Shipping stocks jumped 4% Monday as Iran-linked disruptions at the Strait of Hormuz forced major carriers to suspend vessel crossings. Maersk, Hapag-Lloyd, and CMA CGM diverted services away from the region citing rising safety concerns. The moves lifted energy markets, with oil futures up over 7% and prices gaining more than 4% in early trading.

Morgan Stanley cautioned against reading the moves as a fundamental re-rating, maintaining its "underweight" rating on Maersk. The brokerage argued the Hormuz disruption is "meaningful but not 'Suez scale'" for container flows. Before the Red Sea crisis, the Suez Canal handled approximately 22% of global container traffic, while Gulf ports like Dubai's Jebel Ali represent only 8% of total global container liftings.

For container shipping, Morgan Stanley's base case remains that oversupply persists and pressures rates lower regardless of how the crisis develops. If Suez transits normalize by mid-2026, effective container supply growth hits 6.2% against demand growth of just 3.3%. Even if Suez stays closed, fleet capacity growth of 3.8% still outpaces demand. "Either way, the risk is to the downside on freight rates, notwithstanding short-term dislocations," Morgan Stanley said.
