GAIL share price plunges 6.5%. Why is the Maharatna PSU stock falling despite hike in tariffs?

GAIL share price: Shares of Maharatna public sector undertaking (PSU) GAIL (India) Limited tanked 6.5% in early trade on Friday, November 28, after the Petroleum and Natural Gas Regulatory Board (PNGRB) approved a tariff hike that came in below both market expectations and the company’s own proposal, denting investor sentiment.

After several months of delay, PNGRB has announced a 12% hike in tariffs for GAIL’s integrated natural gas pipeline (INGPL), with effect from January 2026.
