IndiGo stock slides as West Asia conflict hits Q4FY26

What changed for IndiGo after the West Asia flare-up

InterGlobe Aviation, which operates IndiGo, entered FY26 with relatively supportive analyst sentiment before the Iran-related conflict escalated. That backdrop shifted as airspace closures across the Gulf Cooperation Council (GCC) began to disrupt flying schedules and raise operating complexity. IndiGo is exposed to the region through international routes, and disruptions such as the Dubai shutdown add to operational uncertainty. At the same time, crude prices have spiked, bringing fuel-cost pressure back to the centre of airline earnings. Brokerages also flagged that a weaker rupee could compound risks because a meaningful share of aviation costs are dollar-linked.

Stock reaction and brokerage resets

InterGlobe Aviation shares fell sharply intraday after fresh brokerage commentary on near-term risks. The stock tumbled as much as 3 percent to ₹4,381 on the BSE, following UBS lowering its target price to ₹5,480 while retaining a Buy rating. UBS said the ongoing geopolitical conflict could weigh on available seat kilometres (ASK) in the near term, while higher crude creates incremental earnings risk. The brokerage also highlighted that weakness in the rupee against the US dollar could become a medium-term headwind for the sector.

By the end of the session, the stock closed 2.28 percent lower at ₹4,410 per share. The decline followed a prior session where the stock had settled nearly 3 percent higher, underlining how quickly sentiment has turned sensitive to headlines. The stock was also reported down 9.5 percent for the week in the same period.

Flight cancellations linked to airspace restrictions

IndiGo disclosed that it cancelled over 500 flights to the Middle East and selected international destinations from February 28 to March 3 due to evolving airspace restrictions over Iran and other Gulf countries. In its regulatory filing, the airline said it would continue to closely monitor the revenue environment arising from the situation. Such disruptions typically force rerouting and schedule changes, which can increase fuel burn and crew costs. They can also weaken forward bookings if passengers defer travel during periods of heightened uncertainty.

PL Capital quantified the disruption using daily suspended flight counts for early March. Its analysis noted 166 flights suspended on March 1, 162 on March 2, and 156 on March 3, with 57 flights impacted on March 4 so far, calling the figure evolving.

Fuel and currency risks: why margins can move quickly

Brokerage notes focused on the combined effect of airspace disruption and a crude spike. One sensitivity analysis cited in the coverage said every $1 rise in Brent can lead to a 12 to 13 percent drop in IndiGo’s earnings per share (EPS), assuming a constant rupee. That sensitivity matters because airline profitability can swing sharply when fuel prices move while fares adjust with a lag. IndiGo also has limited fuel hedging, which increases exposure to spot fuel price volatility.

Currency is the second variable investors are watching closely. UBS said rupee depreciation against the US dollar could create medium-term headwinds. For Indian airlines, several costs are typically dollar-linked, including leases and other obligations, so a weaker rupee can pressure reported profits even when demand is stable.

What Q3FY26 numbers said, and what they did not

InterGlobe Aviation reported a sharp 78 percent year-on-year decline in consolidated net profit for the December quarter. Net profit was ₹550 crore in Q3FY26 versus ₹2,449 crore in the same quarter last year. The company attributed the steep fall largely to exceptional items, including costs tied to implementation of new labour laws, operational disruptions, and adverse currency movements.

The exceptional charges disclosed were ₹969 crore related to new labour codes, ₹577 crore due to operational disruptions, and ₹1,035 crore arising from currency movements linked to dollar-based future obligations. The company said that excluding exceptional items, profit for the quarter was significantly higher. It reported an underlying net profit of ₹3,131 crore after adjusting for those items. It also stated that profit after tax (PAT), excluding all exceptional and forex impacts, stood at ₹3,846 crore in Q3FY25 terms.

Broker views on Q4FY26: how big could the hit be

Brokerages attempted to translate the cancellations into Q4 impact ranges. HSBC analysts said that if cancellations persist for seven days, they estimate about ₹32 crore could be erased from IndiGo’s profit before tax (PBT), equal to about 6 percent of PBT in the fourth quarter.

PL Capital laid out a more extended worst-case scenario. It said the disruption could result in a 10 percent hit to the airline’s PBT in a worst-case scenario if the suspension persists through March 2026. Since the disruption started in March, PL Capital estimated time-adjusted capacity at risk of 1,836 million ASKM (assuming a one-month impact). Keeping load factor and yield assumptions unchanged, it estimated passenger revenue at risk of ₹841.9 crore. It also estimated an unabsorbed fixed cost hit of ₹273.6 crore for the quarter, and flagged an upside risk to costs if crude prices spiral beyond its fuel cost per ASKM (CASK) assumption of ₹1.55.

Key figures and estimates at a glance

Market impact: why the sector reaction is not limited to IndiGo

The reports noted that escalating tensions are a clear negative for travel and tourism stocks. For airlines, the immediate cost pressure comes from rerouting, cancellations, and crew scheduling changes, typically raising fuel and employee expenses. The second-order effect is demand risk, as customers can cancel bookings and slow new reservations when travel uncertainty rises. UBS said these factors could begin impacting earnings from Q4FY26, which is why it moved to a more conservative near-term valuation approach.

Why brokerages still keep a long-term thesis in place

Despite near-term pressure, UBS said IndiGo’s long-term investment case remains intact and noted that industry downturns have historically favoured efficient players. The brokerage said it would continue to monitor macro and geopolitical risks, and that prolonged stress could potentially lead to a review of estimates. Separately, J.P. Morgan flagged earnings headwinds from higher fuel costs and a moderation in international air traffic linked to the Middle East crisis.

Conclusion

InterGlobe Aviation’s near-term narrative has shifted from post-results positioning to managing operational and cost volatility driven by Gulf airspace disruptions, crude price moves, and potential rupee weakness. The company has already disclosed large flight cancellations linked to the restrictions and said it is monitoring the revenue environment. Investors are now likely to watch how long disruptions persist into Q4FY26, crude price trajectory, and any further brokerage revisions tied to capacity, fares, and cost assumptions.
