Strait of Hormuz Crisis: Naval Blockade, Insurance Surges, and Regional Energy Impacts

Status: RESTRICTED

Shipping Assessment: Commercial transit through the Strait of Hormuz is severely curtailed. The US military has initiated a naval blockade of Iranian ports, while the IRGC has retaliated by seizing commercial vessels, including the US cargo ship Touska. Tanker traffic has collapsed, with dozens of vessels stranded or anchoring outside the strait to avoid targeting risks. A fragile ceasefire extension has allowed a minimal trickle of vessels to transit, but military posturing remains highly aggressive.

Naval Activity: The US Navy is enforcing a blockade, intercepting Iranian cargo vessels. In response, the IRGC Navy has conducted vessel seizures and fired warning shots at commercial shipping. The IRGC has also reportedly laid sea mines in the strait, prompting major shipping firms to suspend operations entirely. Military escorts and political risk insurance interventions are being considered to stabilize the corridor.

Insurance Premiums: Marine insurance markets have weaponized risk pricing, effectively closing the strait commercially. Additional War Risk Premiums surged from a pre-crisis baseline of 0.15 percent to as high as 3 percent of hull value, adding millions of dollars per voyage (). While premiums briefly eased to approximately 1 percent, they have rebounded due to renewed hostilities. Many protection and indemnity clubs have issued 72-hour notices terminating existing war risk extensions.

Price Movement: Brent crude experienced extreme volatility, surging past $100 per barrel and peaking near $126 before retreating to approximately $101.40 per barrel on April 22, 2026 (). The market remains in steep backwardation, reflecting acute near-term supply shortages. Physical crude oil pricing benchmarks have shown extreme sensitivity to Strait-related headlines, with weekly price ranges exceeding $13 per barrel during peak uncertainty periods.

Opec Response: Regional producers are facing severe export constraints due to the inability of tankers to load cargoes safely. With domestic storage tanks filling rapidly, Middle Eastern producers have been forced to implement precautionary production shut-ins. The International Energy Agency estimates that crude production is currently being curtailed by at least 8 million barrels per day. This massive reduction in output is exacerbating the global supply deficit.

Supply Disruption Assessment: The effective closure of the Strait of Hormuz represents the largest disruption to world energy supply since the 1970s. Approximately 20 million barrels per day of crude and product exports are disrupted. Alternative pipeline bypasses, such as those in Saudi Arabia and the United Arab Emirates, offer only 2.6 million barrels per day of spare capacity. This leaves a massive structural deficit in global markets that cannot be resolved without a resumption of maritime transit.

Btc Pipeline: The Baku-Tbilisi-Ceyhan (BTC) pipeline faces severe, verified kinetic threats. Israeli and Azerbaijani intelligence dismantled an IRGC Unit 4000 terror cell that had smuggled explosive drones and 7.73kg of C-4 explosives into Azerbaijan with the explicit intent of attacking the BTC pipeline (). The plot was thwarted, and the pipeline remains operational, but the threat profile for alternative energy corridors is now critical. Security forces have heightened alert levels around the Sangachal Terminal and associated infrastructure.

Other Pipelines: With the Strait of Hormuz restricted, reliance on overland pipelines has increased significantly. However, the IRGC's demonstrated intent to target the BTC pipeline indicates that Iran views regional bypass infrastructure as legitimate targets. This strategy aims to maximize the economic impact of the Hormuz closure by degrading alternative export routes. Operators of the South Caucasus Pipeline and other regional networks must anticipate similar asymmetric threats.

Pakistan: Pakistan is experiencing severe macroeconomic strain from the energy shock, resulting in 6 to 7 hours of daily power load-shedding. To stabilize the Rupee and manage import costs, the State Bank of Pakistan secured a $3 billion deposit from Saudi Arabia. The government also cut domestic diesel prices by Rs 32.12 per liter to provide relief to the logistics sector. Diplomatically, Chief of Army Staff Asim Munir is actively mediating between the US and Iran in Tehran.

Azerbaijan: Azerbaijan is managing direct security spillover from the conflict. Beyond the thwarted IRGC plot against the BTC pipeline, the country is processing thousands of evacuees fleeing Iran via the Astara border crossing. The volatility in oil prices caused Azeri Light crude to fluctuate wildly, dropping to $104.49 before rebounding, complicating near-term fiscal planning. The government is maintaining a heightened security posture along the southern border.

Georgia: As a net energy importer, Georgia faces significant price transmission risks. Fitch Ratings projects Georgia's current account deficit will widen to 5.3 percent of GDP in 2026 due to higher energy and logistics costs (). However, direct physical supply risks are mitigated because Georgia sources the majority of its natural gas from Azerbaijan via infrastructure that is not currently under direct threat. The central bank retains some room to contain broader inflationary effects if the shock persists.

• Immediately secure alternative routing for critical shipments, bypassing the Strait of Hormuz via overland pipelines or the Red Sea where feasible, despite the added transit time.
• Review all marine insurance policies for war risk cancellation clauses; prepare for 72-hour notice terminations and secure emergency underwriting capacity.
• Hedge fuel exposure for Q3 and Q4 2026, as the current backwardation in Brent crude indicates severe near-term supply stress that could persist if the ceasefire collapses.
• Enhance physical security protocols at energy infrastructure assets in the Caucasus, specifically along the BTC pipeline corridor, in response to demonstrated IRGC targeting capabilities.

• IRGC targeting of alternative energy infrastructure:
• Marine insurance market withdrawal:
• Macroeconomic destabilization in net-importer nations:
