State-owned oil marketing companies (OMCs) on 1 September raised prices of 19-kg commercial LPG cylinders by ₹9.50, while aviation turbine fuel (ATF) costs for domestic airlines climbed 5.46% — or ₹6.28 per litre — marking the second straight monthly increase in jet fuel rates.

ATF Hike: Second Consecutive Monthly Rise

The price of ATF has been revised upward from ₹115 per litre to ₹121.28 per litre, effective 1 September. This follows an earlier hike of ₹5 per litre in August, which itself came after a similar cut in July — signalling a reversal of the brief relief domestic carriers had received mid-summer.

Jet fuel accounts for roughly 35–40% of an airline's total operating expenditure in India, making ATF among the most consequential cost variables for carriers. The latest revision is expected to push up fuel bills for domestic airlines, and could exert upward pressure on airfares — though ticket prices are also shaped by passenger demand, route competition, and available network capacity.

Mumbai CNG and PNG Rates Also Revised Upward

Mahanagar Gas Ltd (MGL) has separately raised CNG prices in Mumbai by ₹2 per kg, bringing the new rate to ₹88 per kg. Domestic PNG prices have also been increased by ₹1 per standard cubic metre (SCM), with both revisions effective from 1 September.

MGL attributed the increases to a sharp rise in input gas costs linked to international price indices. 'In view of the ongoing crisis in the Middle East, which has resulted in a significant increase in input gas prices linked to international indices, MGL has announced a revision in the prices of CNG,' the company said in a statement.

Commercial LPG Hike Follows Government Production Mandate

The commercial LPG price revision comes days after the Petroleum and Natural Gas Ministry issued an order specifying maximum LPG production targets for 21 refineries and upstream companies. Combined daily production potential has been set at 63,810 tonnes. The directive, issued in August, covers both public- and private-sector refineries, and is seen as an effort to align supply with demand ahead of the festive season.

Notably, the commercial LPG hike affects hotels, restaurants, and small businesses that rely on the 19-kg cylinder — distinct from the subsidised 14.2-kg domestic cylinder used by households. The domestic cylinder price has not been revised in this round.

What This Means for Consumers and Businesses

The confluence of higher ATF, CNG, and commercial LPG prices on the same date points to a broader pass-through of elevated global energy costs onto Indian end-users. Middle East tensions have kept international gas benchmarks elevated, limiting the ability of domestic distributors to absorb input cost increases.

For commuters in Mumbai dependent on CNG-powered vehicles, the ₹2 per kg increase adds to a cost-of-living squeeze, while PNG-reliant households will see a modest uptick in monthly cooking gas bills. Airlines, already navigating thin margins, face a renewed squeeze on profitability — a dynamic that analysts say could revive discussions around fuel surcharges on domestic routes.

All eyes will now be on whether OMCs follow up with a revision to domestic LPG cylinder prices, and whether international energy prices stabilise or continue their upward trajectory through the quarter.
