The rise in aviation stocks comes even as aviation turbine fuel (ATF), or jet fuel, prices have surged sharply, tracking the spike in global crude oil prices amid the escalating conflict in West Asia. According to official data, ATF prices in New Delhi were increased to Rs 2,07,341.22 per kilolitre (kl), up from Rs 96,638.14 per kl, marking a jump of over 114 per cent. This is the first time jet fuel prices have crossed the Rs 2 lakh per kl mark. "In the short-term, this (price hike) is not good news because around 40-45 per cent of the operational cost is ATF. And, it has no choice but to raise ticket prices. I think this is going to impact its volumes in the near term. But there is also one important thing that IndiGo controls a major chunk of the market share in the aviation sector," market expert Avinash Gorakshakar told Business Today.
