India’s Diesel Exports Reach a One-Year High as Global Supply Tightens

India’s diesel exports climbed to 2.90 million tonnes in October 2026, their highest level in a year, as a squeeze in global supply met high refinery output and strong export economics. Shipments reached 700,000 barrels per day (b/d), up from 620,000 b/d in September, Kpler data showed. The increase puts Indian refiners in a position to supply several major markets, though firm domestic consumption could limit how much more fuel is available for export.

The October total was the highest since September 2025. It reflects a combination of unusually high refinery utilisation, production choices that favour diesel, and attractive margins. Those conditions have allowed India to capture more of the market while supplies from other regions have been constrained.

High refinery runs add export supply

Indian refineries have been operating above 100 per cent utilisation, helped by limited maintenance beyond a few turnarounds and unplanned outages. High utilisation lets refiners process more crude through existing facilities. When maintenance interruptions are limited, they can sustain that throughput and direct a larger volume of refined products toward buyers abroad.

Sumit Ritolia, Kpler’s lead research analyst for refining and modeling, said high utilisation and limited maintenance had enabled refiners to maximise throughput and send more barrels into export markets. India’s large, complex refineries can also adjust their output mix. Ritolia said export-oriented facilities were running in “Max-diesel operations,” tilting yields toward the fuel.

That production flexibility matters when buyers are competing for diesel. Refineries can change the balance of products they make, within the limits of their equipment and operating plans. A higher diesel yield can increase export availability without requiring new refining capacity, though it also means less flexibility to maximise other products at the same time.

India’s scale and export infrastructure help connect that output with customers in Asia, Africa, Europe and the United States, Ritolia said. Access to competitively priced crude, including Russian barrels, further supports refining economics. Together, these conditions have made export sales more appealing at a time when diesel prices relative to crude have offered strong margins.

A global supply squeeze supports sales

The export rise is unfolding against a significant reduction in available diesel and gasoil. The International Energy Agency said disruptions to Middle East exports, alongside lower supply from Russia and some Asian countries, reduced global availability by 1.5 million barrels per day in the second quarter of 2026 and 1.7 million barrels per day in the third quarter compared with the same periods a year earlier. The agency described the resulting market pressure as extreme.

A separate October commentary from the Federal Bank of Dallas estimated that global refinery capacity had declined by as much as 10 per cent, or roughly 8 million barrels per day. It attributed the reduction to a mix of shipping disruption, refinery damage and export restrictions in China and Russia. Capacity constraints can tighten product availability even when crude is accessible: fewer operating refining units mean less fuel can be processed and delivered to end users.

These supply losses have increased the importance of refiners able to maintain high output and reach export markets. India’s October shipments show how quickly a country with available refinery capacity can respond when global buyers face tighter supply. But the figures also depend on continued access to crude, reliable refinery operations and margins that justify directing product overseas.

Local demand could set a ceiling

Ritolia expects Indian refinery runs to stay around 5.6–5.7 million barrels per day, with no major maintenance planned. If those runs hold and margins remain healthy, refiners should be able to sustain strong diesel exports. That outlook still leaves room for domestic conditions to absorb some of the additional output.

Seasonal demand is expected to remain firm, supported by the festive period, freight activity and agriculture. Stable retail prices are another factor in the domestic consumption outlook, Ritolia said. Fuel sold at home is not available for export, so stronger local demand can offset some of the benefit from higher production.

That creates a practical limit on the export surge. Refiners may continue to send substantial volumes abroad, but the balance between overseas margins and domestic sales will shape how much output reaches international buyers. Ritolia expects exports to stay strong without rising much beyond current levels, and views October as the high point for the year. The next signals to watch are refinery utilisation, maintenance and whether local demand absorbs a larger share of production.
