With tensions around the Strait of Hormuz resurfacing in geopolitical conversations, Indian aviation stocks and oil marketing companies are facing a familiar problem: their cost structures can get upended by events they can't control.

A 10% rise in crude prices could compress IndiGo's EBITDAR margin by 150-200 basis points, based on fuel cost sensitivity figures the company has disclosed in past annual rep...
