IndiGo Q4 Loss: ₹2,537 Cr Hit from Rupee Slide

IndiGo's Q4 Loss Lays Bare the Rupee Problem [InterGlobe Aviation](/stock/INDIGO) (NSE: INDIGO) reported a net loss of ₹2,537 crore for Q4 FY25, a result that wasn't entirely surprising but was still worse than most analyst estimates. The rupee's depreciation against the dollar — it averaged around 86-87 to the dollar through much of the quarter — directly inflated three of IndiGo's largest cost lines: aviation turbine fuel, aircraft lease rentals, and maintenance expenses. All three are predominantly dollar-denominated contracts. When the rupee weakens, these costs rise in rupee terms without any corresponding increase in ticket revenues, which are priced in Indian rupees. This is the structural trap that Indian carriers have always lived with. IndiGo earns in rupees, but a significant portion of its cost base behaves like a foreign currency liability. The airline doesn't have meaningful natural hedges here — it can't easily raise fares fast enough to offset a 5-7% currency move, particularly in a price-sensitive domestic market. The Q4 numbers make this vulnerability concrete and quantifiable. Investors who held INDIGO through this period without pricing in rupee risk were, in effect, taking an unintended currency position. It's worth noting that this isn't unique to IndiGo. The same mechanics apply across Indian aviation. The difference is scale: IndiGo operates roughly 300+ aircraft and commands over 60% domestic market share, so the absolute rupee impact on its books is far larger than what any peer would face.

SpiceJet has been navigating financial distress well before this rupee move — the carrier has faced aircraft groundings, delayed salary payments, and creditor disputes over the past two years. A weaker rupee doesn't create SpiceJet's problems, but it compounds them. Any...
