India’s diesel exports climbed to a one-year high in September as record refining margins encouraged domestic refiners to maximise production and sell more fuel overseas. The country exported around 620,000 barrels per day (bpd) of diesel during the month, with Europe absorbing nearly half of those volumes as refinery disruptions and supply constraints pushed up regional fuel prices. Data from commodity analytics firm Kpler showed that India’s September exports were the highest in 12 months.
Europe received around 280,000 bpd of Indian diesel in September, an increase of nearly 80% from August. The surge came as disruptions at refineries in Europe and the Middle East tightened available diesel supplies, creating an attractive market for Indian refiners. At the same time, diesel refining margins rose sharply, giving Indian plants a strong incentive to increase output and exports.
India’s Diesel Exports Reach 620,000 Bpd
India exported approximately 620,000 barrels per day of diesel in September, according to Kpler data cited by The Economic Times.
The jump highlights the country’s growing importance in global refined-fuel markets. India has one of the world’s largest refining systems and is increasingly able to redirect fuel toward markets where margins are most attractive.
The September increase was driven by a combination of strong international diesel prices, elevated refining margins and supply disruptions in competing markets.
India’s September diesel export destinations
| Destination | Approx. exports |
|---|---|
| Europe | 280,000 bpd |
| Africa | 200,000 bpd |
| Asia | 50,000 bpd |
| Americas | 40,000 bpd |
| Other/unknown | 50,000 bpd |
| Total | 620,000 bpd |
Europe therefore accounted for roughly 45% of India’s diesel exports during the month.
Europe Becomes the Biggest Destination
Europe’s demand for Indian diesel increased sharply in September.
Indian shipments to the region reached approximately 280,000 bpd, up around 80% from August.
The increase reflects a broader tightening of Europe’s diesel market. Refinery disruptions in Saudi Arabia, reduced availability of Russian refined products and disruptions affecting Middle Eastern fuel flows have all contributed to tighter supplies.
S&P Global reported that Middle Eastern diesel exports to Europe were heading toward their lowest level in six years during September, while European diesel prices surged to record levels.
This created an opportunity for India to act as a swing supplier — increasing shipments when international markets offer sufficiently attractive returns.
Record Diesel Margins Encourage Indian Refiners
One of the biggest drivers behind India’s export surge was the sharp increase in diesel refining margins.
The Singapore diesel crack spread against Dubai crude — a commonly watched indicator of refinery profitability — was running above $60 per barrel in September, according to Kpler.
A higher crack spread means refiners can potentially earn more by converting crude oil into diesel.
That creates a powerful incentive to maximise refinery utilisation and direct more production toward export markets where prices are high.
Why the diesel crack matters
Crude oil cost → Main input for refiners
Diesel selling price → International revenue
Diesel crack spread → Approximate refining margin
Higher crack → Stronger incentive to produce diesel
When diesel prices rise faster than crude costs, refiners have greater economic motivation to increase diesel production.
India Benefits From Its Large Refining Capacity
India has developed into a major refining hub because of its large, complex refineries and access to crude from multiple producing regions.
The country’s refining capacity currently stands at roughly 267 million tonnes per year, according to Oil Minister Hardeep Singh Puri, and is expected to rise toward 290 million tonnes within a year and around 320 million tonnes by 2030-32.
This capacity gives Indian refiners flexibility.
When domestic demand is relatively stable but international margins rise, refiners can increase exports. When overseas margins weaken, some production can instead be directed toward the domestic market.
That flexibility is becoming increasingly valuable as global refined-fuel markets experience repeated supply disruptions.
Indian Refineries Are Suited to Diesel Production
India’s refinery configuration also supports its position in the diesel market.
Kpler analyst Nikhil Dubey said increased crude supplies from the Gulf and Russia were providing Indian refiners with a crude slate supportive of middle-distillate production, particularly diesel.
Indian refineries are generally configured to produce relatively high yields of middle distillates, which include diesel and other products.
This means the country’s refining infrastructure is well positioned to benefit when diesel margins rise relative to other petroleum products.
Reliance Has an Important Export Advantage
Reliance Industries is one of India’s major fuel exporters, particularly through its export-oriented Jamnagar refinery complex.
The company’s export-focused Jamnagar unit is not subject to India’s windfall tax on diesel exports, according to the Economic Times report.
That gives the export-oriented refinery an advantage when global diesel margins are exceptionally high.
Other refiners, including Reliance’s domestic-focused refinery, Rosneft-backed Nayara Energy and state-run refiners such as Mangalore Refinery and Petrochemicals, also participate in the export market or supply fuel to domestic oil marketing companies.
Windfall Tax Still Limits Export Economics
Despite strong global margins, India’s diesel exports remain affected by the government’s windfall tax.
The export duty on diesel was around $37 per barrel in September, according to the report.
That tax absorbs a significant portion of the internationally available refining margin for refiners subject to the levy.
However, the government has recently reduced the diesel export duty.
From October 1, 2026, India’s diesel export duty was cut to ₹16 per litre from ₹20 per litre, while the duty on aviation turbine fuel was reduced to ₹10.50 per litre from ₹15.
The reduction could improve export economics further if global diesel prices and refining margins remain elevated.
India Sends More Diesel to Africa
Europe was not the only important destination.
India exported approximately 200,000 bpd to Africa during September, making it the country’s second-largest destination.
Another 50,000 bpd went to Asia, while around 40,000 bpd went to the Americas. Approximately 50,000 bpd went to destinations that Kpler could not identify.
The geographical diversity of India’s exports is strategically important.
Rather than relying on a single market, Indian refiners can redirect cargoes toward regions where diesel prices and margins are strongest.
India Has Become a Major Global Diesel Supplier
India’s rising role in diesel exports comes as global trade patterns are changing.
India has already overtaken Russia to become the world’s second-largest supplier of seaborne diesel after the United States, accounting for roughly 10% of global shipments, according to Kpler data cited by the Economic Times.
Russia’s reduced refined-fuel exports following restrictions and geopolitical disruptions have created an opening for alternative suppliers.
India is particularly well positioned because it has both large refining capacity and access to crude from the Middle East and other regions.
China’s Export Restrictions Could Tighten the Market Further
Another major factor is China’s decision to suspend diesel exports in October.
China has historically been an important supplier of refined petroleum products to international markets. A reduction in Chinese exports removes additional supply at a time when diesel markets are already tight.
The combination of lower Chinese exports, reduced Russian availability and disruptions in Middle Eastern refinery and shipping flows could therefore keep international diesel markets under pressure.
For India, this could create further opportunities to increase exports if margins remain attractive.
Europe’s Fuel Shortage Creates an Opportunity for India
Europe is particularly important because the region depends heavily on imported diesel.
The disruption of Middle Eastern supplies has reduced one of Europe’s traditional sources of refined fuel. At the same time, Russia’s role as a supplier has been significantly reduced.
European diesel prices reached record levels during September, with S&P Global reporting a Northwest European diesel cargo price of around $1,642 per tonne at one point in the month.
High prices increase the attractiveness of long-distance shipments from India.
However, shipping costs, freight availability and geopolitical risks remain important factors in determining whether such trade flows remain profitable.
India’s Fuel Export Role Is Becoming More Strategic
The current surge is part of a broader change in India’s position in global energy markets.
India has traditionally been one of the world’s largest crude-oil importers, but its refining industry allows the country to transform imported crude into higher-value petroleum products and export them.
This creates an important economic advantage.
India can import crude from one region, refine it domestically and then export diesel, gasoline or aviation fuel to another region where demand and prices are stronger.
That makes India increasingly important to global fuel supply chains.
The Bigger Picture
India’s September diesel exports demonstrate how quickly global energy disruptions can reshape refined-fuel trade flows. With exports reaching around 620,000 bpd, India is taking advantage of high diesel margins and its ability to produce large quantities of middle distillates. Europe has emerged as the biggest destination, absorbing around 280,000 bpd as its own supply market tightens.
The development also strengthens India’s position as a swing supplier in global diesel markets. Reduced Russian availability, lower Middle Eastern exports to Europe and China’s export restrictions are creating space for alternative suppliers, while India’s large refining system gives it the ability to respond quickly when margins improve.
However, the opportunity comes with risks. Windfall taxes, crude prices, freight costs and geopolitical disruptions can rapidly change export economics. If global diesel margins remain elevated and India’s export duties continue to ease, Indian refiners could maintain a stronger export presence in Europe and other deficit markets.
Looking Ahead
India’s diesel exports are likely to remain sensitive to international refining margins and the availability of competing supplies. The recent reduction in the diesel export duty could improve the economics for refiners subject to the levy, while continued disruptions in Europe, Russia and the Middle East could keep Indian cargoes competitive.
Over the longer term, India’s expanding refining capacity could further strengthen its position as a global refined-fuel supplier. If capacity reaches the government’s targeted levels and Indian refiners continue to access competitively priced crude, India could play an increasingly important role in balancing diesel shortages across Europe, Africa and Asia.
