Wednesday’s ATF pricing story began with panic, moved through correction, and ended with a government intervention. Now that all three chapters have played out, it is worth stepping back and explaining the complete picture in plain numbers because what actually happened is more interesting than any single headline captured.
Here is the full explainer, from what the market demanded to what airlines will actually pay to what the government quietly absorbed on your behalf.
What the Market Actually Demanded
ATF prices in India are deregulated and revised monthly based on a formula linked to international crude oil benchmarks. Under normal circumstances this formula produces modest adjustments of a few percent in either direction.
April 2026 is not normal circumstances.
The Strait of Hormuz has been closed since the Iran war began on February 28, 2026. Brent crude is trading above $115 per barrel. Global jet fuel refining margins have spiked as supply chains have been disrupted across the entire West Asian energy corridor. When Indian OMCs ran their standard April pricing formula against these inputs, the output was unambiguous. Domestic ATF should have increased by more than 100 percent.
In Delhi, that formula-driven price would have been approximately Rs 2,07,341 per kilolitre, up from Rs 96,638 per kilolitre in March. That is the number that appeared briefly on the IOC website Wednesday morning and that triggered the initial wave of alarm. It was not a mistake in the sense of being an incorrect calculation. It was the actual formula output. It was the market price.
What Was Passed Through and What Was Not
The Ministry of Petroleum, in consultation with the Ministry of Civil Aviation, made a policy decision that the full formula price would not be passed through to domestic airlines. Instead a partial and staggered increase was approved.
The approved domestic increase is 25 percent, equivalent to Rs 15 per litre or Rs 15,000 per kilolitre.
Here is what that looks like in a simple breakdown for Delhi:
March domestic ATF price: Rs 96,638 per kilolitre. Formula-driven April market price: approximately Rs 2,07,341 per kilolitre. Total formula-driven increase: approximately Rs 1,10,703 per kilolitre, or roughly 115 percent. Amount passed through to domestic airlines: Rs 15,000 per kilolitre, or 25 percent. Amount absorbed by OMCs: approximately Rs 95,703 per kilolitre, the difference between what the market demanded and what airlines are being charged. Approved April domestic ATF price: approximately Rs 1,04,000 per kilolitre.
In percentage terms the government passed through roughly 13 percent of the total formula-driven increase to domestic airlines and absorbed approximately 87 percent of it within OMC balance sheets.
The International Route Exception
The government’s intervention applies only to domestic routes. Indian carriers operating international flights will pay the full market price increase for April, consistent with what airlines pay for jet fuel at airports across the rest of the world.
This creates a stark two-tier pricing structure. The same Indian carrier filling up at Delhi airport pays approximately Rs 1,04,000 per kilolitre for fuel going into an aircraft on a domestic route and approximately Rs 2,07,000 per kilolitre equivalent for fuel going into an aircraft on an international route.
The logic is that domestic air travel is a public service requiring insulation from extraordinary price shocks while international aviation operates in a competitive global market where all carriers face the same elevated costs and an artificial subsidy for Indian carriers would distort competition unfairly.
What the OMCs Are Absorbing
The difference between the market price and the domestic airline price is being absorbed by India’s PSU oil marketing companies, principally Indian Oil Corporation, Bharat Petroleum, and Hindustan Petroleum. These are the same companies that have been absorbing OMC losses on petrol and diesel throughout the Iran crisis, estimated at approximately Rs 48.8 per litre on retail fuel at various points in the conflict.
On aviation fuel the arithmetic is stark. For every kilolitre of domestic ATF sold in April, OMCs are receiving approximately Rs 95,703 less than international market benchmarks justify. Given the volume of domestic aviation fuel consumed across India’s 95 plus domestic destinations and 2,200 plus daily flights, the aggregate OMC subsidy on domestic ATF in April alone will run to thousands of crores of rupees.
This is a policy choice. The government has decided that the social and economic cost of allowing domestic air travel to absorb the full Iran war fuel price shock is higher than the fiscal cost of having OMCs absorb the majority of the increase. Nayara Energy, which is privately owned and not subject to government pricing direction, has already raised retail fuel prices independently. The PSU OMCs are being held to the government’s preferred pass-through level.
What It Means for Your Ticket
The 25 percent domestic ATF increase will still feed through to ticket prices to some degree. Airlines had already imposed fuel surcharges of Rs 150 to Rs 200 per ticket last month. Those surcharges are likely to be modestly revised upward following the April pricing confirmation. Base fares on competitive routes will also reflect the higher cost environment.
But the scale of fare increase that a 115 percent ATF hike would have produced versus what a 25 percent hike produces is the difference between a manageable adjustment and an industry crisis. A rough approximation: if fuel accounts for 40 percent of an airline’s costs and fuel costs rise 25 percent rather than 115 percent, the total cost base increases by approximately 10 percent rather than approximately 46 percent. The fare increase required to maintain margins is proportionally smaller.
On a Delhi to Mumbai ticket that might have cost Rs 4,500 in March, a 10 percent cost base increase might translate into Rs 500 to Rs 800 of additional fare depending on route competition and demand. A 46 percent cost base increase could have pushed that same ticket well above Rs 6,000 to Rs 7,000 on the same route.
The government’s intervention compressed the passenger impact from the second scenario toward the first.
The Simple Summary
Global markets said jet fuel should cost Rs 2,07,341 per kilolitre for April. The government said domestic airlines will pay Rs 1,04,000 per kilolitre. The Rs 95,703 difference per kilolitre is being absorbed by government-owned oil companies. International flights pay the full market price. Passengers on domestic routes will see higher fares but not the catastrophic doubling that full market pass-through would have produced. And OMC balance sheets will take a hit that will show up in quarterly results in the weeks ahead.
The Iran war’s energy cost shock is real. The government has chosen to absorb most of it rather than pass it to Indian travellers. The bill has not been cancelled. It has been redirected.
