IndiGo Q4 Loss: Rupee, Crude Crush Margins

IndiGo Q4 Loss Signals Structural Pain for Indian Aviation [InterGlobe Aviation](/stock/INDIGO) (NSE: INDIGO) reported a ₹2,537 crore net loss for Q4, a number that should worry every investor with exposure to Indian aviation. The culprits aren't new — a rupee that's slid to approximately ₹95 per US dollar and jet fuel costs tied to Brent crude sitting at $93–94 per barrel — but the magnitude of the hit confirms that these aren't temporary headwinds. They're structural. IndiGo settles a significant portion of its costs in dollars: aircraft leases, maintenance contracts, and fuel procurement are all dollar-denominated or dollar-linked.

[SpiceJet](/stock/SPICEJET) (NSE: SPICEJET) enters this environment from a far weaker balance sheet position. The carrier has been restructuring debt and navigating lessor disputes since FY24, and any sustained crude spike above $90/bbl makes its already-thin operating buffer essentially non-existent. SpiceJet doesn't have IndiGo's scale advantages or...
