India's oil sector faces significant pressure as crude prices have surged 93% since 28 Feb, reaching $136.56 per barrel. This spike is squeezing margins for major refiners, including Indian Oil Corporation and Reliance Industries. With retail fuel prices unchanged, state-run firms are absorbing the impact, raising concerns over growth and inflation. 📉
