IGL share price jumps 6% after ₹2/kg CNG hike

What triggered the move in IGL stock

Shares of Indraprastha Gas Ltd (IGL) climbed as much as about 6% in Tuesday’s trade after the company raised compressed natural gas (CNG) prices by ₹2 per kg. The increase was effective from 6 am on May 26, as per updates attributed to the company. The move marked the fourth CNG price revision since May 15, based on the information cited in the reports.

The immediate market reaction was visible across both exchanges. On the BSE, IGL was reported up 5.95% at ₹170. Another market update showed the stock trading 5.15% higher at ₹168.75 around 09:45 AM. On the NSE, IGL rose 3.92% to ₹166.77 in early trade.

The new CNG price in Delhi and what changed

After the latest revision, CNG in Delhi was reported at ₹83.09 per kg, up from ₹81.09 earlier. The company also communicated that the revised rates came into effect from Tuesday morning across Delhi. Multiple reports described the May 26 increase as the fourth hike in about two weeks, with some describing it as four hikes in 11 days.

The Delhi price point was the most consistently cited figure across the updates. The repeated revisions have kept the CNG price move in focus for commuters and fleet operators in the capital, and for investors tracking city gas distribution (CGD) companies.

Delhi-NCR and other city prices: what was reported

The reports also cited revised CNG prices across the National Capital Region and other IGL markets. For Noida, Ghaziabad and Greater Noida, one update reported the price at ₹91.70 per kg, while another mentioned ₹88.70 per kg for Noida, Greater Noida and Ghaziabad. Gurugram’s price was reported at ₹88.12 per kg.

Outside NCR, Ajmer’s revised CNG price was stated at ₹92.44 per kg, and Chennai was reported at ₹95 per kg in one update. Another line item referenced CNG prices ranging from ₹92.44 per kg to ₹94.42 per kg for regions such as Kanpur, Fatehpur and Hamirpur.

How other CGD and energy stocks traded

The CNG price hike also coincided with gains in other related stocks. Around 09:45 AM, Adani Total Gas was reported up 3.6% at ₹683, while Mahanagar Gas (MGL) gained 3.12% to ₹1,108 per share. ONGC was also reported higher by over 1% at ₹493.10.

The broader move indicated a positive read-through for companies exposed to gas distribution and, in ONGC’s case, the energy value chain. The rally followed a straightforward trigger: a visible, near-term change in retail pricing.

Timeline of the recent CNG hikes cited in the reports

Reports characterised the May 26 action as the latest in a cluster of rapid revisions since May 15. The exact cumulative increase was described differently across updates. One report said the Delhi increase over the period was ₹5 per kg, while another stated the total rise since May 15, 2026 was ₹6 per kg.

The price points below were explicitly mentioned in the updates and show how rates varied by location after the May 26 revision.

Why the hike is happening, as per the reports

The cluster of price hikes was linked in the reports to rising global energy costs. One update also referred to higher global energy prices tied to the ongoing Middle East conflict and disruptions around the Strait of Hormuz. These factors were cited as part of the broader context for fuel price pressures.

Separately, one report also mentioned oil marketing companies (OMCs) raising petrol and diesel prices, with a cumulative rise of nearly ₹7.5 per litre, according to that update. While these references were not presented as a direct driver of IGL’s decision, they were cited to explain the broader pricing environment.

What the market may be focusing on

For investors, the immediate focus was on the speed and frequency of revisions and how that might affect near-term sentiment for CGD companies. The market response suggested that clarity on higher retail pricing, even amid cost volatility, can support stock performance on the day of the announcement.

A technical comment attributed to Rajesh Bhosale of Angel One said the stock saw strong buying momentum, gained more than 4%, and reclaimed key short- to medium-term moving averages. This was presented as a market observation around the day’s move.

Conclusion

IGL shares rose sharply on May 26 after the company increased CNG prices by ₹2 per kg, taking the Delhi price to ₹83.09 per kg with effect from 6 am. The revision was described as the fourth hike since May 15, with other CGD stocks also trading higher. Investors are likely to track further price updates and any additional changes in the energy cost environment cited alongside these revisions.
