India's Diesel Lifeline: A New Era of Eastern Supply for Europe

India's Diesel Lifeline: A New Era of Eastern Supply for Europe

The global energy landscape is undergoing a significant shift, with India emerging as a crucial source of diesel for Europe. According to recent data, Indian refineries supplied approximately 60% of the 2,00,000 barrels per day of diesel that transited the Bab-el-Mandeb in August. This marked a significant increase in India's role in supplying diesel to Europe, as Russian exports remain severely constrained and US shipments begin to weaken.

The Rise of Indian Diesel Exports

India's installed refining capacity exceeds domestic demand, making the country an increasingly important source of eastern diesel supply for Europe. In 2025-26, India exported 61.5 million tonnes of petroleum products, making it one of the largest exporters of refined products globally. These fuels are now finding a market in Europe and Russia, with India's role being most important on the diesel side.

The Decline of Russian Diesel Exports

Russian diesel exports, once a major source of European supply, have remained largely absent. Russia's seaborne diesel and gasoil exports averaged only about 1,50,000 barrels per day in the first 25 days of August, down about 6,10,000 barrels per day from a year earlier and 81% below the five-year seasonal average. The decline in Russian diesel exports is attributed to the ongoing conflict in Ukraine, which has disrupted Russian refining and export infrastructure.

The Impact of US Shipments

US shipments to Europe peaked at almost 5,40,000 barrels per day in the first half of August before falling to about 3,50,000 barrels per day in the second half, a decline of roughly 35%. This decline in US diesel shipments has left Europe increasingly dependent on Indian refiners to maintain eastern supply routes.

The Concentration of European Diesel Supply Chains

The Strait of Hormuz is offering limited relief to the clean-products market, with only 37 crossings by MR2-sized or larger tankers carrying clean products recorded during the first 27 days of August. Ship-to-ship transfers offshore Oman have continued, but most of the activity involves crude rather than refined products. The result is an increasingly concentrated European diesel supply chain, with India playing a growing role.

The Challenge Ahead

The reliability of India's diesel supply to Europe will be put to the test, given its own domestic fuel demand and the potential impact of disruptions to its refining and export infrastructure. Crude and condensate shipments into India fell for a second consecutive month to about 3.8 million barrels per day in August, compared to 4.8 million barrels per day a year earlier. The concern is whether India can maintain this flow, especially during the peak winter diesel-demand period when inventories are already low and refineries on both sides of the Atlantic face autumn maintenance.

Key Takeaways
