IndiGo (NSE: INDIGO) closed Tuesday at ₹3,943, sitting in a precarious zone on the daily chart. The ₹4,046 support, tested and held multiple times since early 2024, broke down in recent sessions. Below current price, ₹3,790 is the only meaningful technical defence left. The chart was already sending a warning. What arrived overnight made it a full alarm.
The ATF Shock: Effective April 1, ATF in Delhi stands at ₹2,07,341 per kilolitre, up 114.5% in a single monthly revision, the steepest jump in India's ATF pricing history and the first time it has crossed the ₹2 lakh mark. For context, the previous peak was ₹1.1 lakh during the Russia-Ukraine crisis in 2022. Today's number is nearly double that.
The trigger is the West Asia conflict, which escalated from February 28 and severely disrupted crude supply through the Strait of Hormuz. International ATF moved from $99 per barrel to over $195 in five weeks.
Why IndiGo Bears the Brunt: Fuel is IndiGo's single largest cost, at 35 to 45% of total operating expenses. At the previous ATF level, margins were already thin. At ₹2.07 lakh, the economics of flying change fundamentally. Fare hikes are coming, the Aviation Minister has confirmed that, but they take weeks to flow through forward bookings. The cost hits today. That lag is the direct threat to Q4 and Q1 FY27 earnings.
Technical Structure
The stock peaked near ₹6,000 in mid-2025 and has shed 34% since. Lower highs, lower lows, and heavier volume on down-moves than recoveries. That is distribution, not accumulation.
Two levels matter now. ₹3,790 is immediate, a gap down at open could test it within the first thirty minutes. Below that, ₹3,430 is the last significant floor on the chart.
What to Watch
The gap down is likely. The real question is whether institutions defend ₹3,790 or step aside. A close below it changes the medium-term picture entirely.
₹3,790 on a closing basis. That is the line between a bad day and a broken stock.
