A closure reaches Indian aviation through fuel cost.
What happens to Indian aviation if the Strait of Hormuz closes?
The chain is six evidenced links long, and each link is a documented dependency rather than an observed correlation. Select a number to read the source.
Most of India's imported crude physically transits the Strait, and west coast refineries are configured for the West Asian grades that come through it. That is why an interruption is not simply a price event. The crude slate can't be re-pointed on the timescale of a closure.
Jet fuel comes out of the same distillation units as diesel, so a limit on refinery runs reaches it directly. Domestic ATF is then repriced on the first and sixteenth of each month against import parity, with state VAT on top. A crude move reaches airline costs within weeks, and unevenly across the route network.
Jet fuel is the largest single line in a scheduled operator's costs. Carriers weighted towards domestic routes have less room to pass an increase through within a quarter. This describes a cost mechanism. It is not a view on any carrier's securities.
What this doesn't establish
- No source we found says how much of a crude move passes through to jet fuel. The chain shows the dependency, not its size.
- Airlines don't disclose hedging in enough detail to time the effect on any one carrier.
