Tankers Entering Hormuz During Iran War Are Making Their Way Out

At least 19 non-Iranian oil and LPG tankers have entered and exited the Strait of Hormuz since March 1, but about 100 others that entered before the conflict remain trapped in the Gulf over attack fears. The article highlights a small but growing group of shipowners willing to transit the chokepoint during the Iran war, underscoring elevated supply-route risk for energy shipping. The situation is geopolitically sensitive and could affect tanker availability, freight costs, and regional energy flows.

Analysis

The market is effectively pricing a bifurcation in tanker risk: a small cohort of operators is earning a wartime scarcity premium, while the rest of the fleet is being pulled into a self-reinforcing “wait-and-see” regime. That is bullish for the handful of asset owners willing to keep vessels exposed, but it also creates a hidden capacity constraint: if more tonnage stays sidelined, voyage durations and effective fleet supply tighten even if headline export volumes hold up. In practice, that is more supportive for spot freight than for crude outright in the first instance, because the bottleneck is transport optionality before it becomes a barrel shortage.

The second-order loser is anyone reliant on Gulf-to-Asia physical arbitrage, especially refiners and commodity traders whose margins depend on predictable liftings and delivery windows. Insurance, war-risk premium, and crew compensation costs should continue to ratchet higher even absent a major incident, which means the real stress may show up in freight rates and backwardation rather than a clean spike in prompt crude. If the market is underestimating anything, it is the lag: the full impact can take several weeks to appear as delayed loadings, reshuffled routing, and inventory drawdowns feed through to Asia.

The key catalyst is not whether a ship can make it through once, but whether the market decides the route is operationally normal again. A single successful passage is not enough to reset behavior; you need a sustained, incident-free window or an explicit de-escalation channel. Conversely, one kinetic event against a non-Iranian tanker would likely freeze the remaining active tonnage and make the current “small group of risk-takers” behavior look like a local peak, not a durable regime.

Consensus may be too focused on immediate oil-price upside and not enough on freight convexity. If the Strait remains open but scary, the best expression is long shipping/tanker exposure against more levered downstream consumers rather than a blunt long crude hedge. The risk/reward favors positions that benefit from elevated volatility and dislocation without needing an actual supply shock, which is the more probable outcome over the next 2-6 weeks.

Key Decisions for Investors

• Long tanker rates via TNK or FRO over the next 2-6 weeks; risk/reward is attractive if war-risk premiums and spot voyages stay elevated even without a supply outage.
• Pair trade: long X-pressured shipping exposure (TNK/FRO) vs short airline/industrial fuel-sensitive names or XLE downstream refiners; thesis is transport friction outruns outright crude appreciation.
• Buy short-dated Brent call spreads or USO calls into any de-escalation dip; the convexity is highest if one incident re-prices routing risk back to the prompt curve.
• Avoid chasing integrated oil longs purely on headline geopolitics; if the channel stays open, the winner is freight, not producers, and crude upside may be capped by inventory release and demand rationing.
• Watch for a 1-2 week accumulation of delayed loadings or spike in Baltic/shipbroking rates; that is the cleaner confirmation signal than spot crude for adding to tanker and volatility trades.
