Four Tankers Reverse Course in Hormuz as Iran Attacks Resume; Shipping Paralysis Deepens
The paralysis is now self-reinforcing. If shipping insurance premiums spike to 5-10% of cargo value (from current ~2%), smaller independent tankers will simply wait.
This concentrates traffic into fewer, larger, more expensive vessels — reducing daily throughput by an estimated 20-30% even if attacks stop. The lag between attack and market adjustment is typically 72-96 hours; if Iran strikes again before Thursday, energy markets will price in sustained disruption rather than a temporary spike. Refineries in South Korea and Japan that depend on Hormuz crude will begin rationing by end of week unless alternative supplies (Saudi, Iraqi, Russian via third parties) materialize.
The tanker reversals signal that commercial risk tolerance has collapsed below the threshold required for routine transit.
This isn't market friction — it's operational paralysis. Every day the strait remains contested, approximately $1.7 billion in daily global oil and LNG flows either reroute through longer, costlier passages (Strait of Malacca adds 10-14 days to Asia-bound shipments) or queue at anchor, creating a hard constraint on energy supply to Europe and Asia.
If the attacks continue at the current pace — three vessels struck in 48 hours — insurers will price transit premiums prohibitively high by end of week, forcing shippers to choose between rerouting or stopping. Watch whether the first major LNG contract gets force-majeure'd by July 15, which would trigger cascading price spikes in European and Asian spot markets.
Are the four tankers that reversed representing the full scope of attempted transits, or are additional vessels queuing outside the strait and not yet visible in tracking data? The article doesn't specify how many total transits were attempted.
