Persistent attacks on tankers—12 incidents logged in early October—have elevated Brent crude to near $101 per barrel and pushed VLCC freight rates from the Middle East Gulf to record levels exceeding $24 per barrel equivalent, underscoring the economic stakes of securing the chokepoint that normally handles about 20% of global seaborne oil. European assets remain positioned in the Arabian Sea under frameworks like EU NAVFOR Aspides, with France, the UK, Germany, and others signaling readiness for mine countermeasures or escort roles contingent on a permissive environment. Heightened GPS jamming, mine threats, and reinsurance costs continue to shape trader assessments of additional naval commitments by December 31.
