What percentage of global trade flows through the Strait of Hormuz?

Approximately 20-30% of global petroleum trade and a significant share of containerized cargo passes through the Strait of Hormuz daily. For energy-dependent regions like Europe and Asia, this figure represents a lifeline; disruption would force immediate rerouting or shortage conditions.

What alternative routes exist if the Strait closes?

The primary alternative is the Cape of Good Hope route around southern Africa, which adds 6,000-7,000 nautical miles and 2-3 weeks of transit time to Asia-Europe voyages. A secondary route via the Suez Canal is not viable as a Hormuz alternative due to geographic constraints. These alternatives are significantly more expensive and capacity-constrained.

Which industries face the highest supply chain risk from a Hormuz closure?

Energy-intensive sectors (automotive, electronics, chemicals, pharma) and industries with Asian supply concentration face the highest risk. Retailers dependent on containerized imports from Asia would also experience severe delays. Energy companies and those with long lead-time sourcing are most vulnerable to price shocks.

How quickly would costs rise if the Strait closed?

Oil prices would spike within hours of closure news, potentially rising 10-30% depending on market conditions and strategic petroleum reserve releases. Transportation costs would increase 15-25% as freight rates adjust for longer routes and reduced capacity. These increases would pressure margins across all sectors within days.

What contingency measures should supply chain teams implement?

Key measures include: (1) mapping supplier exposure to Middle East energy and Asia sourcing, (2) establishing safety stock policies for critical components, (3) diversifying sourcing across geographies, (4) securing long-term transportation agreements pre-crisis, (5) investing in supply chain visibility platforms, and (6) scenario-testing inventory and demand models under 2-3 week Asia-Europe delays.

Strait of Hormuz Closure Threatens Global Supply Chains

The signal

A prolonged closure of the Strait of Hormuz would immediately spike global oil prices and disrupt supply chains worldwide. Daily petroleum trade of 20-30% flows through this 34-mile passage, and alternative African routes add 2-3 weeks to transit times. Transportation costs would rise 15-25%, while Asia-dependent manufacturers relying on just-in-time delivery would face production delays and inventory shortages.

What if the Strait of Hormuz closes for 8 weeks?

Model a scenario where the Strait of Hormuz is closed for 8 weeks due to geopolitical conflict or accident. Simulate the impact on ocean freight routing: reroute all containerized shipments through the Cape of Good Hope, adding 2-3 weeks transit time to Asia-Europe lanes. Assume oil prices spike 20% and transportation costs increase 25%. Assess inventory depletion in Europe and North America, demand fulfillment delays, and margin impact across automotive, electronics, and retail sectors. Apply dynamic safety stock recalculations based on extended lead times.

What if oil prices spike 25% and energy-dependent suppliers reduce output?

Model a dual shock: oil prices jump 25% immediately upon Hormuz closure news, and energy-intensive suppliers (chemicals, pharma, automotive components) in the Middle East and Asia reduce production by 10-15% due to energy cost pressure. Simulate the cascading impact on downstream manufacturers and their ability to meet demand. Track which suppliers face margin compression and potential production halts. Model inventory obsolescence risk if demand softens due to price pass-through. Identify which customers face the highest service level risk.
