Chinese Refiners Bid Record Premiums for Russian ESPO Amid Iran Oil Disruptions and Middle East Risks

Chinese independent refiners are paying record premiums for Russia's East Siberia-Pacific Ocean (ESPO) crude blend, with November cargoes trading at more than $7 per barrel over Brent and offers reaching $10/bbl, according to traders cited by Bloomberg. This surge replaces previously favored Iranian barrels that have dried up following the U.S. naval blockade on Iran, compounded by supply disruptions from the Iran conflict affecting Persian Gulf shipments via the Strait of Hormuz. ESPO's quick transit time from Russia's Kozmino port—under a week to Chinese ports—has made it especially attractive. Data from Kpler and Vortexa show China retaining 83% market share of ESPO exports in the first seven months of 2026, down from 88% a year earlier, while India's share rose to 16% from 12%. Overall Kozmino loadings increased 6% year-over-year. Indian refiners have turned to ESPO as a backup amid slumping Chinese imports in May-June and delayed Middle East term cargoes, despite preferring Urals and facing longer, costlier voyages. India's overall Russian crude imports eased in August from July peaks due to Ukrainian strikes on Russian infrastructure and renewed Chinese competition. These shifts underscore deepening Russia-Asia energy interdependence amid Western sanctions and regional conflicts, with premiums flipping from historic discounts to records as competition for prompt, high-quality barrels intensifies. Broader implications include heightened energy security concerns for Asia, potential upward pressure on global benchmarks from constrained supply, and accelerated diversification away from Hormuz-dependent routes.
