Hormuz crisis intensifies: Iran closes vital strait again after brief opening

reopening the Strait of Hormuz, the Iranian Supreme Command decided Saturday to completely block the passage again. The move follows the ongoing U.S. blockade of Iranian ports. For international shipping, it marks an abrupt return to a state of maximum uncertainty and operational challenges.
On Friday, there seemed to be a diplomatic thaw when Tehran announced it would reopen the strait to commercial shipping. Saturday morning, as a gesture of goodwill, the country even allowed a series of tankers carrying fossil fuels and chemicals to pass through toward the Indian Ocean.
Hopes for a structural easing quickly faded, however. Iran argues that the strait will not remain truly open until the U.S. blockade of their own export terminals is completely lifted. With the US sticking to its strategy, Tehran has again hermetically closed the maritime corridor to ships of "the aggressors" and their allies.
The renewed closure of this strategic bottle neck "through which normally about 20% of the world's oil and gas flow passes forces the logistics industry to make immediate adjustments. The consequences are immediate:
• Operational delays: Ships that were already en route to the Gulf region must change course or anchor in safe waiting areas, leading to acute congestion.
• Rising costs: The uncertainty is putting direct upward pressure on oil prices and the associated fuel surcharges (BAF).
• Risk premiums: Insurers are immediately raising premiums for sailing in war zones even further, which increases overall transportation costs.
The current situation underscores just how fragile international trade routes are. While we are seeing a decline in container rates in other parts of the world due to overcapacity, the situation in the Middle East remains the biggest “wild card” for logistics planning. The “new normal” demands a high degree of agility from shippers; a route that is open today may be closed tomorrow.
