IndiGo, SpiceJet drop as ATF tops ₹2 lakh/kL

Why airline stocks came under pressure

Indian airline stocks traded sharply lower as a spike in crude oil prices lifted expectations of higher Aviation Turbine Fuel (ATF) costs. InterGlobe Aviation, which operates IndiGo, featured among key laggards on benchmark indices in a session marked by risk-off sentiment. SpiceJet also slipped as investors reacted to the sector’s high sensitivity to fuel prices and operational disruption. The immediate trigger was a sharp move in Brent crude amid escalating tensions involving Iran, Israel, and the United States, along with concerns around Gulf airspace restrictions. With fuel forming a large part of airline costs, even short-term price spikes tend to translate quickly into margin anxiety. The broader market mood was also cautious, with crude-sensitive stocks facing selling pressure across sectors.

What happened to IndiGo and SpiceJet in trade

Multiple reports cited steep intraday declines for IndiGo and SpiceJet during the sell-off, with different lows reported across sessions as the oil shock built up. IndiGo was reported down 2.79% to ₹4,434, with an intraday low of ₹4,431.90 on the NSE in one update. Another market snapshot placed IndiGo down 6.37% at ₹4,265.6 on the BSE at 9:17 AM, which was also cited as its intraday low. A separate report said IndiGo fell as much as 8.4% to an intraday low of ₹3,894.80. SpiceJet was reported down 2.58% to ₹14.35 in one update, while another report referenced a fall to ₹9.53, and a separate session noted a 10% lower circuit level of ₹10.85. These moves reflected how quickly airline stocks reprice when fuel costs and flight disruptions rise simultaneously.

ATF hits record levels, raising quarterly loss concerns

The core driver cited for the sell-off was the jump in ATF prices. ATF prices in Delhi were reported to have touched a record ₹2,07,341 per kilolitre, and another update said jet fuel prices breached ₹2 lakh per kilolitre. One report described the broader aviation sector as dealing with a 115% surge in ATF costs since April, raising concerns of deep quarterly losses. Another cited ATF having surged over 130% month-on-month, highlighting the speed of the cost shock. Research commentary in the same set of reports noted ATF typically accounts for about 40% of an Indian airline’s operating expenses, with other updates placing the range at 30% to 45%. With airlines operating on thin margins, the jump in fuel costs is difficult to absorb without adjusting fares or imposing surcharges.

Crude oil surge and West Asia tensions

Crude prices were repeatedly highlighted as the source of the fuel cost shock. One update referenced Brent crude hovering near $110, while another said Brent crude climbed above $107 per barrel. A separate market note cited Brent crude futures up 7.32% at $102.17 per barrel. As the conflict narrative intensified, another report said Brent surged $14.39, or 26.31%, to $117.08 a barrel, alongside mentions that global crude crossed $115 per barrel during the sell-off. The same set of reports linked the oil move to disruptions and supply concerns tied to the US-Israel-Iran war and additional volatility around the Strait of Hormuz.

Airspace restrictions, cancellations, and longer routes

Operational disruption added to investor concerns beyond fuel pricing. Reports said the conflict reshaped flight operations across the Middle East, with large portions of Gulf airspace turning restricted. As of one update, over 350 international flights had been cancelled by Indian airlines, with disruptions continuing into the next day. It also noted technical stops being added on some routes, including Rome for North America-bound flights. Airlines including IndiGo, Air India, and SpiceJet were referenced as adjusting operations to manage the situation. Longer routings and additional stops increase fuel burn, and that becomes more damaging when ATF is already at elevated levels.

How sensitive are airline earnings to Brent crude

The reports included estimates to quantify IndiGo’s exposure to crude movements. One update said that for every $1 rise in Brent crude, IndiGo could see up to a 13% decline in Earnings Per Share (EPS). Another note, attributed to JM Financial Institutional Securities in the same compilation of updates, stated that every $1 per barrel increase in Brent crude could result in an estimated 13% decline in EPS, assuming fares are not increased. Both estimates were presented as a way to explain why airline stocks react quickly to oil moves. The common point across these references is that profitability can swing sharply when crude rises and airlines cannot immediately pass through higher fuel costs.

Surcharges, partial pass-through, and policy backdrop

Airlines and policymakers were also referenced in relation to how much of the shock can be passed through. IndiGo was reported to have raised fuel charges effective April 2 across domestic and international routes. For domestic operations, one report said the government allowed only a 25% staggered pass-through of the increase, described as about ₹15 per litre, limiting the immediate impact on ticket prices. Domestic fuel charges were cited as ranging from ₹275 for routes up to 500 km to ₹950 for routes above 2,000 km. Another update said international fuel surcharges were increased significantly, particularly on long-haul routes such as South Asia to Europe, where charges were cited in a range of ₹900 to ₹10,000. Separately, the government decision to lift temporary caps on domestic airfares from March 23, 2026 was cited as an additional variable for pricing and demand.

Spillover across the aviation ecosystem and broader market

The selling pressure was not limited to airlines. GMR Airports was cited as falling 3.4% in one update, while another market check reported GMR Airports down 3.89%, Dreamfolks Services down 3.74%, and TAAL Tech down 1.33%. The broader market tone also turned weak in several updates, with one report noting the Sensex falling over 2,400 points during the oil shock. Another said the sell-off wiped out nearly ₹13 lakh crore of investor wealth within hours during a sharp early decline. Crude-sensitive sectors such as auto, paint, and tyre stocks were also referenced as coming under pressure when oil crossed $115 per barrel.

Key figures mentioned in the reports

Analysis: why the move matters for investors

The sell-off underlined the market’s focus on cost visibility in a business where fuel is structurally the largest variable expense. When ATF rises sharply and route disruptions force longer flying times, airlines face a double hit: higher per-hour fuel burn and higher per-unit fuel pricing. The reports also highlighted that fare pass-through may be constrained in the near term, including references to staggered increases and the earlier period of airfare caps. Research commentary cited an earnings overhang for IndiGo from airspace disruption, driven by network dislocation, revenue loss, and elevated cost pressure, with cancellations and booking softness flagged as potential headwinds for Q4FY26 performance. With crude moving above $100 and even crossing $115 in parts of the coverage, the market reaction reflected the view that survival and yield protection can take priority over growth when fuel spikes.

Conclusion

IndiGo and SpiceJet shares fell as ATF hit record levels above ₹2 lakh per kilolitre, while Brent crude surged on West Asia tensions and airspace disruption. Alongside cancellations and longer routings, the fuel shock sharpened investor focus on margins and near-term earnings risk. The next markers cited in the reports include monthly ATF price revisions, the extent of fare and surcharge pass-through, and how quickly flight networks normalise as airspace restrictions evolve.
