Why Oil Supply Disruptions in Asia Could Persist Even After the Strait of Hormuz Reopens

Oil supply chains operate on long cycles: tankers already scheduled or diverted must reposition, ports must sequence arrivals, and refineries must adjust procurement plans. As a result, even a fully reopened corridor would still leave Asian importers waiting for delayed shipments.

Insurance Costs Are Still Blocking Tankers

Another major constraint is maritime insurance.

During the conflict, war‑risk insurance costs for ships operating near the Strait of Hormuz surged from under 1% of cargo value to roughly 3%–10%, dramatically increasing the cost of voyages.

For many shipowners and charterers, these premiums make the route financially unattractive or risky even after hostilities decline. Some insurers also cancelled or repriced coverage during the crisis, which discouraged vessels from entering the Gulf in the first place.

Until insurance markets stabilize, tanker availability through the strait is likely to remain limited.

Shipping Companies Are Still Avoiding the Route

Many major shipping and logistics firms halted or reduced operations during the crisis. Some carriers suspended Gulf services entirely or diverted cargo to alternative ports, while others imposed new risk surcharges on shipments.

Even after ceasefires or political agreements, companies often wait for sustained stability before resuming normal operations. This cautious approach means the physical reopening of the waterway does not automatically bring back the fleet capacity needed for normal oil trade.

Security and Mine‑Clearing Concerns

Security is another factor slowing recovery. Analysts and officials have warned that clearing mines or other hazards from the waterway could take significant time, potentially months depending on the scale of the threat.

Although the exact timeline remains uncertain and some officials have disputed specific estimates, the broader reality remains: shipping companies and insurers typically require verified safe corridors before restoring full traffic.

Asian Importers Are Already Reshaping Supply Chains

Because the disruption lasted months, Asian economies have already started adjusting their crude sourcing.

India provides one of the clearest examples. As Gulf supplies tightened, refiners increased purchases from alternative producers including Russia, West Africa, and Venezuela. Venezuela alone supplied about 417,000 barrels per day to India in May, making it the country’s third‑largest crude supplier for that period.

However, such substitutions are only partial solutions. Venezuelan crude tends to be heavier and can only be processed efficiently by certain complex refineries, limiting how much it can replace Middle Eastern grades across the broader system.

What This Means for Asian Economies

For the region’s largest oil importers, the main impact is timing and cost rather than a permanent loss of supply.

Even if diplomatic negotiations reopen the Strait of Hormuz, Asian economies could still experience:

• Delayed crude deliveries due to shipping congestion
• Higher freight and insurance costs
• Temporary refinery adjustments or inventory drawdowns
• Continued diversification toward non‑Gulf suppliers

In other words, a political agreement may reopen the chokepoint—but restoring the global oil logistics network that depends on it could take months.
