Hormuz lanes still constrained

Ships are moving through the Strait of Hormuz again, but many are no longer using the normal shipping lanes that made the route predictable. Operators are hugging narrower, controlled corridors instead, which means the waterway is open on paper but still constrained in practice. (gcaptain.com) That matters because the Strait of Hormuz is the narrow sea gate between Iran and Oman that carries roughly a fifth of the world’s oil and a huge share of liquefied natural gas from the Persian Gulf to the open ocean. When traffic through one chokepoint becomes selective, every refinery, tanker owner, and fuel buyer downstream feels it. (insurancejournal.com) The immediate problem is not a formal closure but a new system of control. Lloyd’s List reported on April 9 that Iran was asserting authority with transit rules, threats of force, and what it described as an evolving but still unofficial toll system linked to the Islamic Revolutionary Guard Corps. (lloydslist.com) That has turned a routine tanker voyage into something closer to negotiating passage through a checkpoint. Some ships are reportedly using secret codes and yuan-denominated payments to get through, which shows how commercial traffic is being filtered by politics rather than normal maritime procedure. (insurancejournal.com) The price of that uncertainty is showing up first in insurance. Owners have been filing unusually large war-risk insurance requests before passages, and marine insurers have been repricing Gulf cover even after the ceasefire because the ceasefire did not restore normal routing freedom. (insurancejournal.com) (lloydslist.com) Oil flows are recovering more slowly than the headlines around a truce would suggest. Analysts told World Oil on April 9 that exports through Hormuz would come back only gradually, which keeps tanker rates, bunker fuel costs, and delivery schedules under pressure for longer. (worldoil.com) The backlog is large enough that even a clean restart would not fix it overnight. Lloyd’s List said more than 600 vessels were still stuck in the Middle East Gulf on April 9, and estimated that clearing them would take more than 10 days even if traffic instantly returned to pre-conflict levels. (lloydslist.com) India is now one of the loudest governments pushing back on this new reality because its energy trade runs straight through the strait. Indian officials have kept calling for “free and safe” navigation while saying there has been no discussion with Iran about paying any transit toll. (indianexpress.com) (hindustantimes.com) The toll reports are still hanging over the market anyway. Indian and regional reporting says some ships have faced demands of up to $2 million to cross, while Iran’s embassy has publicly called those claims unfounded, leaving shipowners to make decisions in a fog of denials, exceptions, and case-by-case deals. (hindustantimes.com) (indianexpress.com) That is why “open” is not the same as “normal.” A tanker route works like a highway only when every ship knows the lane, the rules, the price, and the insurer will still cover the trip, and Hormuz still does not meet that test on April 10, 2026.
