India predominantly imports and processes a blend of sour (high sulfur) and sweet (low sulfur) crude oil to optimize refining margins. The Indian basket, used to track imports, consists of approximately sour (Oman/Dubai) and sweet (Brent) crude.

Key Aspects of India’s Oil Blend

Composition: The Indian basket typically holds a ratio near 75:25, though this varies slightly depending on international market prices and supply availability.

Source Orientation:

  • Sour Grade (High Sulfur): Primarily sourced from the Middle East (Saudi Arabia, Iraq, Kuwait) due to its lower cost per barrel.
  • Sweet Grade (Low Sulfur): Used as a blending agent to reduce overall sulfur levels, often sourced from Western regions or utilized from local production like Mumbai High.
  • Refining Economics: Indian refineries, such as those operated by Reliance Industries and IOCL, are highly sophisticated, enabling them to process lower-cost, high-sulfur (sour) crude into valuable, eco-friendly fuels (Euro-VI compliant).

Why the Mix Matters:

  • Cost Savings: Sour crude generally costs $4–$10 less per barrel than sweet crude.
  • Strategic Flexibility: Blending ensures efficient operations while optimizing the gross refining margin, balancing heavy, low-cost feedstock with lighter, cleaner crude.
  • Recent Trends: The shift toward importing discounted Russian oil has increased the proportion of medium-sour grades in the Indian blend, fitting the country’s diesel-heavy demand profile.

Impact on Crude Oil Pricing and Refining

  • The “Sour Discount”: Sour crude typically costs $4–$10 less per barrel than sweet Brent crude. By maintaining a high ratio of sour crude (currently around 61.02% for March 2026), India significantly lowers its average cost of raw materials.
  • Indian Basket Composition: The Indian Basket price is a weighted average derived from Sour grade (Oman Dubai average) and Sweet grade (Brent Dated). Changes in the global price of either grade, or a shift in the import ratio, immediately shift this benchmark.

Current Price Trends (2025-2026)

  • Recent Peak: The Indian Basket price reached $115.75/bbl as of 26 March 2026, a sharp increase from the $69.01/bbl average seen in February 2026.
  • Economic Exposure: Every $1 increase in the per-barrel price of this sour-sweet mix adds roughly $1.5–$2 billion to India’s national import bill, which can impact inflation and the value of the Rupee.
  • Price Forecasts: While some analysts like J.P. Morgan forecast Brent to average $60/bbl in 2026 due to oversupply, others like Standard Chartered expect prices to remain higher, averaging $85.50/bbl for the year.

Strategic Shift in Import Share

  • Dominant Supplier: Russia became India’s top oil supplier, with its share peaking near 40% in 2023-2024, up from just 1.7% pre-2022.
  • January 2026: Russian imports hit a 44-month low (roughly 19.3% share) as India diversified toward U.S. and Gulf oil amid trade negotiations with the Trump administration.
  • March 2026: Imports surged back toward all-time highs (approx. 60 million barrels) as Indian refiners pivoted away from the volatile Middle East following conflict in the Strait of Hormuz.

Economic Impact on Import Costs by Russian oil

  • Total Savings: India saved approximately $5.1 billion in FY2023 and $7.9 billion in the first 11 months of FY2024 by switching to Russian oil.
  • The “Urals Discount”: Historically, Urals offered steep discounts of $20–$30 per barrel compared to Brent in 2022-2023. However, this discount narrowed to roughly $3.50–$5 per barrel by late 2025.
  • Recent Price Reversal (March 2026): Following disruptions in the Strait of Hormuz and a temporary U.S. sanctions waiver, Urals prices spiked, briefly trading at a $1.70–$6 premium over Brent for Indian delivery.
  • Refining Margins: Discounted Urals provide a high yield of middle distillates (diesel and jet fuel), which are essential for India’s demand profile and help domestic refiners maintain strong Gross Refining Margins (GRM).
  • Freight & Logistics: Costs for transporting Russian oil to India have risen significantly, recently reaching $15 million per Aframax vessel, up from $10–$12 million, further squeezing the net benefit of the trade.
