Strait of Hormuz Crisis: Transit Plummets 80% Following Iranian Closure Declaration

Status: RESTRICTED

Shipping Assessment: Commercial transit through the Strait of Hormuz dropped 80 percent following the June 20 closure declaration by the Islamic Revolutionary Guard Corps (IRGC). Analytics firm Kpler reported only five vessels crossed the waterway on June 21, compared to 26 ships the previous day . The transiting vessels included three Very Large Crude Carriers carrying two million barrels of Saudi crude each. Many operators are instructing captains to switch off location transponders to conduct dark transits. This severe reduction in tanker availability directly impacts charter rates for Western energy importers.

Naval Activity: The IRGC Navy halted the issuance of passage permits for commercial vessels on June 21 (Iranian state media, reflects regime position) . This action violates the June 17 memorandum of understanding that guaranteed free passage. US Central Command maintains a naval presence in the region and reported escorting 55 merchant ships carrying 17 million barrels of oil prior to the renewed closure . The conflicting operational control creates extreme navigational hazards for civilian crews.

Insurance Premiums: The renewed threat of interdiction has paralyzed the marine insurance market. Underwriters are hesitant to provide war risk coverage for Persian Gulf transits, driving premiums to prohibitive levels. Ship owners face potential bankruptcy if vessels are seized or destroyed, making them highly risk-averse . Operators must factor these elevated insurance costs into their downstream pricing models, which will inevitably increase the final cost of delivered fuel and petrochemicals.

Price Movement: Global crude benchmarks erased their recent losses following the Hormuz closure announcement. Brent crude futures climbed 1.4 percent to $81.69 per barrel in early trading on June 22 . West Texas Intermediate futures rose to $78.62 per barrel . The price spike reflects immediate market panic over supply constraints. Buyers should anticipate continued volatility as political negotiations in Switzerland dictate daily market sentiment.

Opec Response: Regional producers are actively developing workarounds to bypass the Hormuz chokepoint. Abu Dhabi National Oil Company and Kuwait Petroleum Corporation issued tenders offering crude loading options from terminals outside the Persian Gulf . Separately, Iraq announced plans to gradually restore crude oil production to 4.3 million barrels per day . These measures provide limited relief but cannot fully replace the 20 million barrels per day that normally transit the strait.

Supply Disruption Assessment: The physical oil market remains exceptionally tight. Prior to the June 20 closure, Iran exported 36 million barrels of crude oil in a single week. The sudden halt of these volumes creates an immediate supply gap. Downstream operations, including fertilizer and plastics manufacturing in South Asia and Europe, face imminent feedstock shortages if the blockade persists beyond 14 days.

Btc Pipeline: The Baku-Tbilisi-Ceyhan (BTC) pipeline remains fully operational and serves as a primary alternative to Persian Gulf shipping. The Organization of the Petroleum Exporting Countries reported a 9.4 percent drop in oil exports via the pipeline in April 2026 . Western operators increasingly rely on this route to move Caspian crude to European markets. The infrastructure requires heightened security monitoring as regional tensions drive more volume through the Middle Corridor.

Other Pipelines: An underwater Azneft pipeline in the Caspian Sea suffered mechanical damage on June 19, likely caused by a ship anchor . The incident triggered an oil spill near Dubendi beach in Azerbaijan, forcing the State Oil Company of Azerbaijan Republic (SOCAR) to suspend transport through the line for repairs. In Pakistan, armed militants attacked an Oil and Gas Development Company Limited convoy near the Sindh-Balochistan border twice within 12 hours on June 17 . These incidents expose the vulnerability of secondary energy logistics networks.

Pakistan: Islamabad is acting as a primary mediator in the US-Iran negotiations in Switzerland, seeking to stabilize regional energy flows . Domestically, the country faces severe logistics disruptions. Armed insurgents opened fire on commercial fuel tankers traveling along the N-40 highway in Noshki, Balochistan, destroying vehicle tires and halting transport . This violence directly threatens fuel supplies for regional mining operations and forces logistics managers to seek costly alternative routes.

Azerbaijan: The country is positioning itself as a stable energy supplier to Europe given the Middle East crisis. SOCAR recently signed 10-year contracts to supply two billion cubic meters of gas annually to German companies . Localized operational risks persist, demonstrated by a June 18 fire at the SOCAR oil refinery in Baku . Emergency services extinguished the blaze quickly, preventing major supply disruptions.

Georgia: Georgia is capitalizing on its position as a secure transit hub connecting the Caspian Sea to European markets. Prime Minister Irakli Kobakhidze visited Tajikistan on June 19 to integrate Central Asian cargo into the Middle Corridor . This diplomatic push aims to route more energy and commercial freight through Georgian ports and railways, bypassing Russian and Iranian territories. Western logistics firms should evaluate Georgian transit options to mitigate Hormuz-related delays.

• Reroute critical petrochemical and fertilizer shipments away from the Persian Gulf where possible, utilizing Red Sea or overland corridors to avoid Hormuz interdiction risks.
• Secure long-term charter agreements for vessels operating outside the Middle East to insulate supply chains from sudden spikes in spot market freight rates.
• Audit marine insurance policies for war risk exclusion clauses and secure supplementary coverage for any assets currently transiting the Gulf of Oman.
• Evaluate the Middle Corridor (via Azerbaijan and Georgia) as a primary logistics alternative for Central Asian commodities, given the persistent volatility in traditional southern routes.

• Implementation of the 60-day US-Iran roadmap and technical talks:
• Escalation of insurgent attacks on energy logistics in Balochistan, Pakistan:
• Expansion of Middle Corridor energy transit via Azerbaijan and Georgia:
