Russian oil cargoes swing back to India as Iran war hits supply


What Happened

  • Two Russian oil tankers that had been signalling East Asia as their destination switched course toward India, as the ongoing Iran conflict raised fears of supply disruptions through the Strait of Hormuz.
  • Approximately 9.5 million barrels of Russian crude are aboard vessels near Indian waters and could be delivered within weeks, offering Indian refiners quick relief amid Middle East supply uncertainty.
  • Specific vessels include the Suezmax tanker Odune (730,000 barrels) arriving at Paradip on India's east coast, and the Aframax tanker Matari (700,000+ barrels) heading to Vadinar in western India.
  • Indian refiners had recently reduced Russian oil purchases to avoid disrupting trade relations with Washington, pivoting Moscow toward Chinese buyers — but the Hormuz crisis has reversed this trend.
  • About 40% of India's crude oil imports move through the Strait of Hormuz, making supply disruptions there an immediate threat to India's energy security.

India's Crude Oil Import Diversification Strategy

India is the world's third-largest oil importer, consuming over 5 million barrels per day, with domestic production meeting less than 20% of needs. To manage energy security, India deliberately diversifies its import basket across geographies, avoiding over-dependence on any single supplier or transit route.

  • Russia became India's largest single oil supplier in 2022-23 following the Ukraine conflict and Western sanctions, as Indian refiners accessed heavily discounted Urals crude.
  • At its peak, Russian oil accounted for over 35-40% of India's crude imports, displacing traditional Gulf suppliers.
  • India sources crude from the Middle East (Iraq, Saudi Arabia, UAE), Russia, the US, West Africa, and Latin America — a deliberate multi-vector strategy.
  • In early 2026, Indian refiners had begun scaling back Russian imports to manage diplomatic optics with Washington, demonstrating the tension between energy economics and geopolitical alignment.

Connection to this news: The Iran conflict has immediately reversed the de-Russification trend, as India's energy security imperatives override short-term diplomatic considerations — illustrating why strategic autonomy in energy policy remains essential.

Strait of Hormuz: The World's Critical Oil Chokepoint

The Strait of Hormuz, located between Iran and Oman, connects the Persian Gulf to the Gulf of Oman and Arabian Sea. It is the world's most important maritime oil chokepoint and a critical node in global energy supply chains.

  • In 2024, oil flow through the Strait averaged 20 million barrels per day (b/d), representing approximately 20% of global petroleum liquids consumption and over one-quarter of total global seaborne oil trade.
  • About 84% of crude oil and condensate moving through Hormuz goes to Asian markets; China, India, Japan, and South Korea collectively accounted for 69% of Hormuz crude flows in 2024.
  • The strait is only 33 km wide at its narrowest point, with two-way traffic restricted to two 3.2 km lanes in either direction.
  • India's dependence: ~40% of Indian crude imports transit through Hormuz, making any disruption there an acute energy security event.

Connection to this news: The fear of Hormuz closure or disruption is the proximate cause of the Russian cargo diversion to India — Russian Arctic and Baltic crude reaches India through the Cape of Good Hope route, entirely bypassing the Middle East chokepoint.

India's Energy Security Framework

Energy security is identified as a critical component of India's national security in multiple policy documents including the Integrated Energy Policy (2006) and the National Energy Policy. India's approach involves supply diversification, strategic petroleum reserves, and development of alternative energy sources.

  • India maintains Strategic Petroleum Reserves (SPR) at three locations — Visakhapatnam, Mangaluru, and Padur — with a combined capacity of 5.33 million metric tonnes (~39 million barrels).
  • India's SPR covers approximately 9-10 days of net oil imports, far short of the IEA-recommended 90-day minimum.
  • The government has announced plans to expand SPR capacity at Chandikhol (Odisha) and Padur (Karnataka) as Phase II.
  • Russian oil imports enabled savings estimated at $35+ billion between 2022-2024 due to discounts relative to benchmark prices.

Connection to this news: The rapid swing back to Russian oil highlights India's SPR inadequacy — if Hormuz disrupts supply, India's buffer is thin, making supply diversification and rapid import reorientation critical near-term responses.

Key Facts & Data

  • Russian oil cargo diverted: ~9.5 million barrels currently aboard vessels near Indian waters (as of March 2026).
  • Odune (Suezmax): 730,000 barrels, arrived Paradip; Matari (Aframax): 700,000+ barrels, en route to Vadinar.
  • India's Hormuz dependence: ~40% of crude imports transit the Strait.
  • Global Hormuz traffic: ~20 million b/d, 20% of global petroleum consumption, 25%+ of seaborne oil trade.
  • Asian markets receive 84% of Hormuz crude; India, China, Japan, South Korea = 69% combined.
  • India's SPR capacity: 5.33 MMT (~39 million barrels) at 3 locations — approximately 9-10 days of cover.
  • Russia's peak share of Indian imports: 35-40% in 2022-23 following Ukraine conflict.
