The Strait of Hormuz remains choked by a massive U.S. naval blockade, but over 20 commercial vessels managed to transit the critical chokepoint in the past 24 hours, according to U.S. officials. The movement marks a trickle of activity through a waterway that normally handles 130-plus ships daily.
President Trump announced the blockade Sunday after weekend peace talks in Islamabad between U.S. and Iranian officials collapsed. The operation involves more than 10,000 U.S. forces, over a dozen warships, and dozens of aircraft positioned to control all maritime traffic entering or leaving Iranian ports.
Naval Blockade Creates Shipping Chaos
Six merchant ships have already turned back following U.S. orders since the blockade began at 1400 GMT Monday. The operation targets Iranian-linked and U.S.-sanctioned vessels but allows humanitarian shipments to pass.
Among the vessels that successfully transited were two cruise ships, Mein Schiff 4 and Mein Schiff 5, along with tankers carrying oil, naphtha, and methanol. The Rich Starry tanker moved approximately 250,000 barrels of methanol through the strait. Five other commercial vessels sailed through since Monday.
Fabrizio Coticchia, professor of political science at Italy’s University of Genoa, explained the U.S. strategy: “The United States does not need to block every type of ship or enter the Strait of Hormuz; it can carry out an intermittent blockade. Ships will not be attacked, but rather diverted.” U.S. warships are positioned outside the strait in the Gulf of Oman, intercepting and diverting vessels rather than engaging them directly.
Traffic Collapse From War Escalation
The current crisis began 28 February 2026 when joint U.S.-Israeli strikes hit targets across Iran. Tehran responded by attacking and threatening vessels in the Gulf, bringing shipping traffic to a near standstill. An average of 100 ships per day passed through the strait in February before the escalation. That number plunged to just 6 to 7 ships daily between 1 March and 12 April.
A two-week ceasefire declared 8 April briefly reopened the strait, with traffic rebounding slightly to 8 ships per day. The numbers remain catastrophically low compared to normal operations. Between 50 and 60 percent of vessels transiting the strait are typically tankers carrying oil and liquefied gas.
The Strait of Hormuz serves as gateway for roughly 25% of the world’s maritime oil trade. An average of 20 million barrels per day of crude oil and oil products shipped through the waterway in 2025. Current throughput sits below 2% of normal daily deadweight tonnage.
Economic Impact Escalates
The blockade’s economic consequences ripple across global markets. Daily costs exceed $4 billion as supply chains fracture and energy prices spike. Brent crude oil prices have surged with 21% of the world’s oil supply and 25% of global LNG trade at risk.
War risk insurance premiums have exploded to over 16 times normal rates. Underwriters typically review coverage every 48 hours given the volatile security situation. Weekly insurance costs now run into hundreds of thousands of dollars for vessels attempting the passage.
Tanker spot rates have tripled for Gulf-to-Asia routes as carriers reroute via the Cape of Good Hope. The alternative path adds up to 14 extra transit days and substantially higher fuel costs. South Korea and Japan face particularly critical impacts as major energy importers dependent on Middle Eastern supplies.
Freight Forwarders Navigate New Reality
The crisis forces cargo solutions providers to completely rethink routing strategies and cost structures. Comparing rates and transit options across multiple carriers and routes has become essential as traditional lanes remain blocked. Forwarders must quickly quote alternative routings and absorb dramatic increases in insurance and fuel surcharges.
BRS ship brokers issued a stark assessment: “A return to ‘normality’ in the Middle East arguably now appears more distant than it did one week ago, especially given that the U.S. navy has started a blockade. It is anticipated that there will be little or no commercial traffic in the strait for the foreseeable future.”
International Condemnation Mounts
China’s foreign ministry condemned the U.S. blockade as “dangerous and irresponsible.” Iran’s military went further, labelling the operation “piracy” and blaming Washington’s “maximalism, shifting goalposts and blockade” for the collapse of peace negotiations.
The diplomatic impasse shows no signs of resolution. Iranian officials refuse to accept terms they view as unreasonable whilst the U.S. maintains the blockade will continue until Tehran meets its conditions. Meanwhile, global shipping bears the cost.
Industry Perspective: Long-Term Likely
The intermittent nature of the blockade creates maximum uncertainty for shippers, oil companies, and insurers. Vessels face unclear guidance on whether passage attempts will succeed or result in costly diversions. Port congestion builds in alternative loading locations as tankers queue for substitute routes.
For freight forwarders and logistics providers, the situation demands agility. Traditional rate agreements collapse when primary lanes close. Customers need rapid requotes as routing options shift daily. The ability to quickly compare multi-carrier options and present alternatives separates competitive forwarders from those left scrambling.
Market intelligence suggests this crisis will persist for months rather than weeks. Forwarders who adapt their quoting systems and partner networks now will maintain service levels whilst competitors struggle. Building relationships with carriers on alternative routes and securing space allocations before spot rates climb further provides crucial advantage.
Frequently Asked Questions
How many ships normally transit the Strait of Hormuz daily?
Approximately 60 to 130 ships pass through the Strait of Hormuz on a typical day. Before the current crisis began in February 2026, around 100 ships per day transited the waterway. Between 50 and 60 percent of these vessels are tankers carrying oil and liquefied natural gas. Current traffic has collapsed to near zero with only occasional vessels making the passage.
Why is the Strait of Hormuz so important for global trade?
The Strait of Hormuz handles roughly 25% of the world’s maritime oil trade, with an average of 20 million barrels per day of crude oil and petroleum products passing through in 2025. It also carries 25% of global LNG trade. The 21-mile-wide waterway at its narrowest point represents the only sea route from the Persian Gulf to open ocean, making it irreplaceable for energy exports from Saudi Arabia, Iran, Iraq, Kuwait, Bahrain, Qatar, and the UAE.
How much do war risk insurance premiums cost now?
War risk insurance premiums have surged to over 16 times normal rates for vessels attempting to transit the Strait of Hormuz. Weekly insurance costs now reach hundreds of thousands of dollars. Underwriters review coverage every 48 hours given the rapidly changing security situation. The extreme premiums reflect the real risk of vessel seizure, diversion, or damage in the conflict zone.
What alternative routes are ships using?
Ships are rerouting via the Cape of Good Hope at the southern tip of Africa, bypassing the Strait of Hormuz and Suez Canal entirely. This alternative adds up to 14 extra transit days and significantly increases fuel consumption and crew costs. The longer route has caused tanker spot rates to triple for Gulf-to-Asia routes. Port congestion is building at alternative loading points as vessels queue for revised routings.
When will the Strait of Hormuz reopen to normal traffic?
Industry experts anticipate little to no commercial traffic in the strait for the foreseeable future. The blockade depends on resolution of diplomatic talks between the U.S. and Iran, which collapsed over the weekend. A brief ceasefire in April allowed limited passage but traffic remained below 10% of normal volumes. No timeline exists for lifting the blockade as both sides maintain hardline positions.
