India emerges as key diesel supplier to Europe as Russian, US flows falter
India supplied roughly 60% of the diesel transiting the Bab-el-Mandeb strait bound for Europe in August, out of an estimated 200,000 barrels per day moving through the strait toward European markets
Russian seaborne diesel and gasoil exports fell sharply, averaging around 150,000 barrels per day in the first 25 days of August — about 610,000 bpd lower than a year earlier and roughly 81% below the five-year seasonal average
US seaborne diesel exports to Europe also weakened, slipping from a first-half-of-year peak of about 540,000 bpd to around 350,000 bpd in the second half, even as total US shipments stood near 520,000 bpd in August
Indian refineries, whose installed capacity substantially exceeds domestic demand, filled the resulting gap in Europe's eastern diesel supply
India's Refining Capacity and Petroleum Product Export Position
India is the world's fourth-largest oil refiner, with an installed refining capacity of about 258.1 million tonnes per annum (MTPA) spread across 23 refineries (public sector, private, and joint-venture), a capacity base that structurally exceeds domestic fuel consumption and allows sustained large-scale exports of refined products such as diesel and petrol, even though India imports over 85% of the crude oil it refines.
Key Details
- India exported approximately 61.5 million tonnes of petroleum products in FY 2025-26 (April 2025-March 2026)
- Major refining hubs include Jamnagar (Reliance, the world's largest single-location refining complex) and Vadinar (Nayara Energy, in which Rosneft holds a stake) in Gujarat, along with public-sector refineries under IOCL, BPCL, and HPCL
- India's refining-based export model — importing crude, refining domestically, exporting the finished product — is distinct from being a crude oil producer, since India's own crude output meets only a small fraction (roughly 15%) of its refining throughput
India's spare refining capacity is precisely what allows it to redirect finished diesel to Europe as Russian and US supply falters, converting an existing refining surplus into a swing-supplier role during a global diesel shortfall.
The EU's Russian Oil "Refining Loophole" Ban and the Price Cap Mechanism
Western sanctions on Russia generally prohibit direct imports of Russian crude oil into the EU, but historically did not restrict imports of refined fuel products made from Russian crude at a third-country refinery — a gap widely termed the "refining loophole" that let countries like India and Turkey import discounted Russian crude, refine it, and export the diesel/petrol to sanctioning countries. The EU closed this loophole with a measure effective from 21 January 2026, requiring importers of refined fuel to prove it was not produced from Russian crude oil, and separately lowered the G7-coordinated price cap on Russian crude from US$60 to US$47.60 per barrel.
Key Details
- The EU has separately sanctioned the Vadinar refinery in Gujarat (in which Rosneft, Russia's state oil company, holds a 49% stake) as part of its Russia sanctions packages
- The G7/EU/Australia price cap coalition allows Russian crude to be shipped using Western insurance and tankers only if sold at or below the capped price; because not all G7 members apply matching rules uniformly, gaps in enforcement persist
- India has consistently maintained it will source crude oil based on national economic interest and has not accepted the legal validity of unilateral, non-UNSC sanctions regimes
Because the EU's refining-loophole ban targets diesel made specifically from Russian crude, India's continued large-scale diesel exports to Europe indicate refiners are increasingly documenting non-Russian crude origin for EU-bound cargoes, or exporting via routes/blends compliant with the new rule, even as they continue to process discounted Russian crude for other (non-EU) markets.
Bab-el-Mandeb — A Distinct Chokepoint from the Strait of Hormuz
The Bab-el-Mandeb strait connects the Red Sea to the Gulf of Aden and the Arabian Sea, separating the Arabian Peninsula (Yemen) from the Horn of Africa (Djibouti and Eritrea); it is the mandatory sea gateway for shipping using the Suez Canal route between Asia and Europe, distinct from the Strait of Hormuz, which governs Persian Gulf oil exports on the other side of the Arabian Peninsula.
Key Details
- Narrowest point: about 18-20 miles (roughly 29-32 km) between Yemen and Djibouti, with shipping lanes just 2 miles wide in each direction
- Handles an estimated 10-12% of global seaborne trade annually and roughly a tenth of global seaborne oil trade, making it the third-busiest oil chokepoint after the Strait of Hormuz and the Strait of Malacca
- Security incidents involving Houthi attacks on shipping near Bab-el-Mandeb and the Red Sea since late 2023 have periodically forced vessels to reroute around the Cape of Good Hope, altering diesel and crude flow patterns to Europe
Diesel cargoes "transiting the Bab-el-Mandeb" specifically refers to the Suez Canal-linked route from the Gulf/Indian Ocean to Europe; disruption risk on this route (from regional conflict) is a separate variable from the Russian and US supply declines but affects the same eastern-Europe diesel flow being discussed.
- India's share of diesel transiting Bab-el-Mandeb toward Europe in August: approximately 60%, out of about 200,000 bpd total volume on that route
- Russian seaborne diesel/gasoil exports (first 25 days of August): approximately 150,000 bpd, about 81% below the five-year seasonal average
- US diesel exports to Europe: fell from a first-half 2026 peak of 540,000 bpd to about 350,000 bpd in the second half, with total August shipments near 520,000 bpd
- India's installed refining capacity: approximately 258.1 million tonnes per annum, world's fourth-largest, across 23 refineries
- India's petroleum product exports in FY 2025-26: approximately 61.5 million tonnes
- EU's refined-fuel "Russian crude origin" disclosure rule took effect 21 January 2026; G7 price cap on Russian crude lowered to US$47.60 per barrel
