Mahanagar Gas Ltd (MGL) witnessed a sharp decline of up to 5% in its share value on April 9, following its announcement of an increase in Compressed Natural Gas (CNG) and Piped Natural Gas (PNG) prices in the Mumbai Metropolitan Region (MMR).

According to the company’s latest price revision, CNG will now cost ₹79.50 per kg, up by ₹1.50, while PNG used for domestic cooking will cost ₹49 per kg, reflecting a ₹1 increase. This marks MGL’s first CNG price hike since December 2024, when the price was raised by ₹1, and before that, ₹2 in November 2024.

Stock Market Reaction
The immediate reaction from investors was negative. MGL’s stock dropped as much as 5% on the Bombay Stock Exchange (BSE) shortly after the announcement. The decline reflects investor concerns about reduced demand and margin pressures on the city gas distributor due to higher input prices and reduced affordability for consumers.

IGL Also Joins the Price Hike Trend
Indraprastha Gas Ltd (IGL) also followed suit, announcing a CNG price hike of ₹1 to ₹3 per kg across its markets. In Delhi, the rate has been raised by ₹1 per kg, taking the new price to ₹76.09 per kg. For consumers in Noida and Ghaziabad, the revised price now stands at ₹84.70 per kg after a ₹3 increase.

This is the first CNG price hike in the Delhi market since June 2024. With Delhi contributing about 70% to IGL’s total CNG sales, the hike is a significant move impacting both end users and the company’s market performance.

What Triggered the Price Hikes?

The driving force behind the recent price revision by both MGL and IGL is the increase in the Administered Price Mechanism (APM) natural gas price, effective April 1. The central government raised the APM gas price by 4%, which is about $0.25 per mmBtu, pushing the new price to $6.75 per mmBtu from the previous $6.50 per mmBtu.

This gas is mainly produced by Oil and Natural Gas Corporation (ONGC) and Oil India Ltd, and is supplied at subsidised rates to city gas distribution companies to ensure affordability of CNG and PNG to the general public.

However, the recent increase in APM gas rates has escalated the input costs for distributors like MGL and IGL, forcing them to pass on the burden to consumers to maintain financial sustainability.

Impact on Consumers and City Gas Companies
The hike in prices comes as a blow to middle-class households and public transport operators, who rely heavily on CNG for commuting and PNG for cooking. This may lead to reduced CNG consumption and potential shift back to petrol or diesel-based vehicles for some consumers.

At the same time, city gas companies are struggling with balancing profitability and consumer affordability. While they face cost pressure from higher raw material prices, frequent hikes could lead to demand erosion and public dissatisfaction.

Comparative Pricing Across Cities
The revised CNG and PNG prices after the latest hikes are as follows:

This price disparity highlights how regional factors and sourcing costs influence pricing by different city gas distributors.

Previous Price Revisions
The current hike is part of a trend seen over the past several months. Here's a quick look at recent price hikes by MGL:

• November 2024 – CNG increased by ₹2/kg

• December 2024 – CNG increased by ₹1/kg

• April 2025 – CNG increased by ₹1.50/kg, PNG increased by ₹1/unit

Government’s Role and APM Pricing Policy
The Administered Price Mechanism (APM) was originally designed to ensure equitable access to energy resources. However, the recent hike has raised concerns about its effectiveness in protecting consumer interests amid global energy price fluctuations.

Though APM gas is cheaper than imported LNG, the rising cost of domestic gas extraction and currency depreciation are contributing to the upward pressure on APM gas prices.

Investor and Market Sentiment
Market analysts believe the recent drop in MGL stock is a reflection of concerns that rising prices may dampen demand, especially in urban centres where alternatives like petrol or electric vehicles are becoming more viable.

There is also uncertainty over how future natural gas price revisions by the government will impact the cost structure and margins of these companies.

What Lies Ahead for Consumers and Companies?
With no clear indication from the government on future gas price controls, city gas distributors will continue to operate in a volatile pricing environment. If international crude prices and LNG imports remain high, further price hikes in domestic CNG and PNG cannot be ruled out.

Consumers may have to adjust their budgets accordingly, while companies like MGL and IGL may need to explore efficiency measures and technological innovations to keep costs under control.

Conclusion
The recent CNG and PNG price hike by Mahanagar Gas Ltd and Indraprastha Gas Ltd marks a significant event in India's energy sector. While it reflects growing input cost pressures, it also brings forth the challenges of balancing consumer affordability with company sustainability. The government’s decision to increase APM gas prices plays a central role in this development, and its ripple effect on transportation costs, household budgets, and company stocks is being closely watched by both market participants and the public.
