Greek PM says tolls for ships to cross Hormuz would be unacceptable, a risk to freedom of navigation

About 20% of global oil and LNG transits the Strait of Hormuz; Greek PM Kyriakos Mitsotakis said it would be unacceptable for ships to pay tolls Iran has proposed, calling such fees a dangerous precedent for freedom of navigation. Tehran, which controls the chokepoint, has suggested fees amid ceasefire talks, while U.S. President Trump floated a possible joint toll scheme and the White House said priority is reopening the strait without limitations. Greece — which controls one of the world’s largest merchant fleets by capacity — warned any international agreement must not include per-transit fees.

Analysis

The mere suggestion of transaction fees at a major chokepoint changes shipping economics even if never implemented. Owners of specialized tonnage that ply Persian Gulf routes (tankers, LNG carriers, LPG) can capture outsized cashflows because re-routing or added port calls convert fixed daily operating costs into a larger per-voyage margin; a 10–20% increase in voyage time typically translates to a >10% lift in time-charter-equivalent revenue for owners and a similar rise in spot freight indices within weeks.

Insurance and war-risk premia are the immediate transmission mechanism to markets: P&I clubs and hull insurers will reprice exposures within days, lifting voyage breakevens and widening the gap between contracted and spot economics — an environment that benefits less-levered owners and harms integrated shippers with thin margins. Over 1–6 months this creates a bifurcation: equity for owners and insurers rerate higher, while energy-importing manufacturers and freight-forwarders face pass-through cost pressure, pressuring margins and inventories.

Policy and military responses are the dominant path to reversal. A credible, enforceable international transit arrangement or visible naval escort (weeks–months) would compress war-risk premiums and reverse freight spikes quickly; conversely, partial enforcement (escorts for flagged vessels only) or a sanctioned ‘toll’ system that routes revenue through intermediaries would entrench higher structural transits costs and create a multi-year negative externality for freedom of navigation norms, with knock-on inflation implications for energy and shipping-sensitive sectors.

Key Decisions for Investors

• Buy equity exposure to tanker owners: initiate long positions in Euronav (EURN) and Frontline (FRO), sized 1–2% NAV each, with a 1–3 month horizon. Rationale: levered upside to short-term spikes in dirty/clean tanker rates; set tactical stop-loss at -20% and take-profit tier at +40–50% as freight indices reprice.
• Acquire leveraged LNG-shipping exposure via options: buy 3–6 month at-the-money call options on Golar LNG (GLNG) sized to 0.5–1% NAV. Rationale: LNG shipping tightness is the highest-convexity outcome if Gulf passage becomes contested; downside limited to premium, upside multiple >3x if charter rates reprice.
• Relative-value pair to isolate freight shock: long Frontline (FRO) and short United Airlines (UAL) equal-dollar, 1–3 month horizon. Rationale: energy/transport disruption should boost tanker cashflows while pressuring airline margins; expected asymmetry 2:1 upside vs downside if disruption is short-lived.
• Hedge macro exposure with commodity calls: buy a 3-month Brent call spread (e.g., long $85 / short $95) sized to offset 25–50% of energy-exposed portfolio delta. Rationale: a sustained chokepoint premium would lift oil and product prices; spread limits cost while capturing politically driven upside.
