Jamnagar Holds the World’s Refining Crown as Global Oil Supply Faces Fresh Threats

The Middle East war has disrupted oil shipments through the Persian Gulf, forcing fuel importers to look beyond their established suppliers.

India’s Jamnagar complex, the world’s largest single-site refining facility, is among the major exporters supplying diesel and gasoline to international markets.

European demand for diesel has supported Indian fuel shipments, although restrictions on products refined from Russian crude have complicated sales to European buyers.

Reliance Industries, which operates Jamnagar, purchases oil from Russia and other producers while supplying markets subject to different import rules.

US Secretary of State Marco Rubio visited Jamnagar on October 21 after proposing that Reliance increase its processing of Venezuelan crude and consider investing in Venezuela’s oil industry. No agreement on additional purchases or investment was announced.

The US proposal introduces another option for securing crude as Reliance manages its Russian purchases and exposure to disrupted Middle Eastern supplies.

The outcome could affect Jamnagar’s feedstock costs and access to export markets beyond the current conflict.

Jamnagar’s 1.4 Million-Barrel Capacity Supports Global Fuel Exports

Reliance Industries operates two refineries at Jamnagar in Gujarat, with a combined crude-processing capacity of 1.4 million barrels per day.

One primarily serves export markets, while the other supplies domestic and overseas customers.

The complex has a Nelson complexity index of 21.1 and can process heavy, high-sulphur crude into diesel, gasoline and aviation fuel. Reliance says its facilities have handled more than 240 crude grades.

Reliance’s export-oriented refinery processed an average of 757,000 barrels of crude daily between April and August 2026, exceeding its nominal capacity of 700,000 barrels, according to Indian oil ministry data.

In September, Reliance exported approximately 929,000 barrels per day of clean petroleum products, accounting for more than 70% of India’s exports in that category, according to shipping figures cited by Business Standard.

Diesel and gasoil accounted for 489,000 barrels of daily shipments, followed by gasoline at 195,000 barrels and aviation fuel at 101,000 barrels.

The export volumes establish the scale of Reliance’s international fuel business. The markets receiving those shipments, and the restrictions affecting their delivery, will influence how much of Jamnagar’s processing capacity can be used profitably.

Jamnagar’s Fuel Exports Face New Restrictions in Global Markets

Reliance Industries ships refined petroleum products from Jamnagar to markets in Europe, Asia and the Americas.

European diesel demand has become particularly important to Indian exporters, with S&P Global Commodity Insights reporting that India’s middle-distillate shipments reached a one-year high in September 2026 as European inventories tightened.

The Centre for Research on Energy and Clean Air (CREA) identified seven petroleum-product cargoes unloaded at European Union ports in September from refineries processing Russian crude.

Six came from Jamnagar. Italy received three of the seven shipments, Romania two, and Spain and Cyprus one each.

A separate 104,000-tonne gasoil cargo from Jamnagar was still travelling toward Rotterdam at the end of September. CREA also recorded €122 million in petroleum-product exports from the complex to the United States during the month.

Across India, Türkiye and Brunei, refineries processing Russian crude exported approximately €1 billion in petroleum products to countries imposing sanctions on Moscow in September, an increase of 43% from August. European Union imports from the facilities covered by CREA reached €667 million.

European Union restrictions on petroleum products made from Russian crude took effect on January 21, 2026.

CREA has urged the bloc to tighten enforcement at individual refineries, arguing that existing exemptions could permit products linked to Russian oil to enter the European market.

Its proposal to restrict shipments from facilities that processed Russian crude during the preceding six months has not been adopted as EU policy.

Security risks along the Red Sea route can also affect deliveries to Europe. Tankers diverted around southern Africa face longer voyages and potentially higher freight and insurance costs, reducing the margins available on some shipments.

The restrictions place greater importance on how Reliance sources crude for its export-oriented operations.

Purchases that offer attractive refining margins may carry additional commercial risks if the resulting petroleum products face limits in major overseas markets.

Russian and Venezuelan Oil Shape Jamnagar’s Crude Supply Strategy

Russia accounted for 32% of Jamnagar’s crude imports between July and September 2026, according to the Centre for Research on Energy and Clean Air (CREA).

Deliveries fell 27% in September amid stronger competition from Chinese buyers and Western pressure on India’s oil purchases.

India’s completed imports from Venezuela averaged 190,000 barrels per day during 2026, according to S&P Global Commodity Insights. Approximately 80% arrived at Sikka port, which serves the Jamnagar area.

Reliance Industries can process Venezuelan heavy crude grades such as Merey-16 at Jamnagar, where its refining equipment is designed to handle high-sulphur oil.

On October 20, US Secretary of State Marco Rubio said Washington wanted Reliance to process more Venezuelan crude and consider investing in the country’s oil production.

Rubio visited Jamnagar the following day and met Reliance Chairman Mukesh Ambani and Executive Director Anant Ambani.

Reliance said the discussions covered international energy developments and possible commercial partnerships. Neither side announced an agreement on additional purchases or investment.

S&P Global reported that 13.6 million barrels of Venezuelan crude, including cargoes still in transit, were expected to reach Indian ports in October, compared with 10.2 million barrels discharged in May.

Venezuela’s ability to sustain larger shipments remains uncertain after years of underinvestment in its oil industry.

Additional production would have to reach Indian refiners at prices competitive with other available grades.

Russian oil discounts could still make purchases attractive to Reliance, although restrictions on petroleum products refined from Russian crude may limit sales to some overseas buyers.

The company must weigh those restrictions against the cost of obtaining alternative supplies.

Washington’s proposal could expand Reliance’s access to Venezuelan oil, but no additional supply commitment has been announced.

The terms of future purchases will determine whether Venezuela takes a larger share of Jamnagar’s crude imports.

Dangote’s Expansion Could Challenge Jamnagar’s Refining Lead by 2029

President Donald Trump’s October 16 waiver of new sanctions and tariffs targeting Russian energy purchases has eased the threat of additional US penalties for Indian refiners.

Existing restrictions remain, and Washington’s next move could depend on negotiations with Moscow over Ukraine.

A settlement that brings broader sanctions relief could make Russian crude more accessible to Reliance Industries.

The Middle East war could complicate Jamnagar’s crude purchases before any diplomatic agreement takes effect.

Further disruption to Gulf exports would increase competition for available supplies, while continued demand for alternative fuel shipments could support Reliance’s overseas sales.

A reopening of disrupted routes would ease pressure on crude markets and could narrow refining margins.

Nigeria’s Dangote refinery plans to expand its capacity to 1.4 million barrels per day by 2029, matching Jamnagar’s current installed capacity.

If completed, the expansion would end Jamnagar’s exclusive position as the world’s largest single-site refining complex.

Reliance faces the prospect of another refinery matching its scale while US sanctions and the Middle East conflict affect the cost of running its existing facilities.

Dangote’s 2029 expansion target could mark the end of Jamnagar’s uncontested capacity lead, even if Reliance remains one of the world’s largest exporters of refined fuel.
