India’s strong diesel shipments raise an obvious business question: what did the exports earn? The answer needs more than a count of barrels leaving port.
S&P Global Energy reported on October 13 that Commodities at Sea estimated India’s September gasoil exports at 586,000 barrels a day, 43% above average loadings in the first half of 2026. This is its gasoil measure, not its broader middle-distillate total.
Kpler’s October 21 analysis put West Coast India–Rotterdam diesel for November arrivals roughly $60–70 per tonne below third-party break-even. These are modelled economics, not realised earnings; the public article does not itemise every cost or contract term.
The periods and geographic scopes differ. September’s nationwide outflows cannot be turned into realised losses using a later model for one route.
The calculation for a cargo
A third-party trader buys finished diesel for resale. Arbitrage compares the destination price with purchase and delivery costs; a negative result leaves a modelled shortfall. Kpler found Rotterdam less unfavourable than Singapore for diesel from India’s west coast. Relative destination economics can matter even when a third-party route is below break-even.
Consider a fictional shipment, unrelated to either provider’s figures. Per tonne, a trader pays a refinery $900 and expects $80 in delivery and other transaction costs. A destination sale at $950 leaves a $30 shortfall: $950 minus $900 minus $80.
The refinery’s $900 receipt is revenue before its own costs. The trader’s $30 shortfall says nothing by itself about the refinery’s profit. All these prices are invented, not current market quotations.
The refinery has another starting point
A refinery starts with crude and processing costs, not the trader’s purchase price for finished diesel. Its business also includes income from the other products it makes.
A “crack spread” compares wholesale product prices with crude prices. The US Energy Information Administration explains that this familiar refining indicator omits some product revenues and refining costs beyond crude. It is therefore not the refinery’s final profit.
A refinery’s actual sales and cost records would be needed to establish realised profit. The fact that it produced the fuel does not make its crude, processing or delivery costs disappear.
What the export figures leave open
For India’s export story, stronger cargo volumes establish scale. Claims about who earned more still need sales and cost evidence for the same period. The useful reading of a trade headline starts by identifying the product, the dates and the business whose earnings are being discussed.
