Strait of Hormuz Blockade Traps Ships, Disrupts Global Oil Flow

Conflict and Closure
The conflict that began on 28 February 2026 between a U.S.–Israeli alliance and Iran sealed the 21-mile Strait of Hormuz, which carries 20 % of oil and gas. After the 8 April ceasefire, it stayed closed. The IMO estimates 1,600 vessels are stranded; Kpler reports 750 have transited since shutdown.
Human Impact
Sailors on vessels report stress and supply shortages. Captain Hassan Khan notes calm outside but anxiety inside. Chief engineer Rashedul Hasan says water for 180 tonnes costs $11,000, up from $1,500–$2,000. Food scarce, temperatures exceed 30 °C, missile threats persist; IMO records 39 vessel attacks and 11 deaths since war began.
Traffic Collapse
Traffic of 100 cargo ships per day has dropped to a handful. CNN reported seven vessels passed on a recent Friday, with four more the next weekend. The cut removed 20 % of oil supply for 94 days, prompting spikes. Freight rates surged; Greek tanker Heidmar posted a 200 % revenue rise in Q1 2026.
Official Responses
Central Command spokesperson Capt. Tim Hawkins confirmed communication with ships but denied escort missions. IMO secretary-general Arsenio Dominguez urged upholding freedom of navigation and rejecting tolls. Iran briefly said the strait would be “completely open” after ceasefire, then reversed after sanctions. Bangladesh Shipping Corporation’s plan to pay Iran’s fees was halted by U.S. threats. OPEC+ sources expect a July output increase of about 188,000 bpd despite disruption.
Criticism & Safeguards
Shipping executives reluctant to resume service. Kpler’s Matt Smith called traffic “exceptionally depleted,” and Los Angeles port director Gene Seroka stressed guarantees. Critics warn weaponising the strait could set a precedent and oppose transit fees.
Conflicting Reports
Kpler says 750 vessels have transited the strait, while CNN notes seven ships passed on a recent day, indicating limited data on total traffic. IMO’s estimate of 1,600 trapped ships may also be imprecise.
Quotes
- “It is really strange that everything looks normal outside, but people inside are not calm.” — Captain Hassan Khan, sailor
- “We purchased about 180 tonnes of water for the ship two days ago… Now, it costs us $11,000.” — Rashedul Hasan, chief engineer, Banglar Joyjatra
- “These ships use bright lights… the Iranians are doing this to stop anyone from passing through.” — Sajid Masood, cook
- “I call on the industry to stand with IMO in defending the principle of freedom of navigation, including the rejection of tolls and discriminatory transit measures.” — Arsenio Dominguez, IMO secretary-general
Outlook
OPEC+ will meet in Vienna to decide the July output target; analysts warned Hormuz-related supply disruptions could last through year-end. Shipping firms say a guarantee of safe passage—likely via diplomatic agreements rather than fees—is needed before regular traffic resumes.
