The International Energy Agency’s March 2026 report contains a section that received far less attention than the headline supply numbers but may ultimately affect more people than any other part of the document. Buried beneath the barrel counts and production tables is a warning about what happens when LPG and naphtha stop flowing from the Gulf — not to oil traders and energy ministers, but to the households cooking dinner, the factories making plastic bottles, and the petrochemical plants that supply the raw materials for almost everything manufactured in the modern world.

The IEA’s language is precise and deliberately understated, as it always is. Read carefully, it describes a cascade that is already beginning and has no quick fix.

India Is Explicitly Named — and the Warning Has Already Come True

The IEA singles out India and East Africa as the regions most immediately exposed to the LPG supply disruption, flagging cooking and heating gas as directly at risk from the Hormuz shutdown. This is not a forecast. It is a description of something already happening.

India imports significant volumes of LPG from Gulf producers — Saudi Aramco’s Saudi CP price is the benchmark against which most Indian LPG contracts are priced, and the physical volumes flow through the same Strait of Hormuz that has now reduced to a trickle of its normal throughput. Gulf producers exported 1.5 million barrels per day of LPG in 2025. That flow has effectively stopped.

The consequences are visible on every street in urban India right now. LPG cylinder prices in Delhi have crossed ₹913 for domestic cylinders. Commercial cylinders used by restaurants, hotels and street food vendors have seen sharper increases and in many areas face outright availability constraints. Induction cooktops are selling out on Amazon, Flipkart, Blinkit and Zepto across Delhi, Mumbai, Bengaluru, Kolkata and Chennai within hours of restocking — a real-time signal of forced mass switching from gas to electric cooking that no government data has yet captured but every retailer is experiencing.

The IEA named India. India confirmed it.

The Petrochemical Warning Most People Missed

The more structurally significant warning in the IEA report is about naphtha — the liquid petroleum product that is the primary feedstock for petrochemical plants producing the polymers that become plastics, synthetic fibres, fertilisers, detergents, paints, pharmaceuticals and thousands of other products that touch daily life in ways most consumers never trace back to an oil refinery.

The IEA states directly that plunging LPG and naphtha supplies are already forcing petrochemical plants to curb their production of polymers, aggravating the loss of Gulf petrochemical flows. The Gulf region is one of the world’s largest exporters of petrochemical products — ethylene, propylene, polyethylene, polypropylene and their derivatives flow from Saudi Arabia, UAE, Qatar and Kuwait to manufacturing hubs across Asia, Europe and the Americas.

When that flow stops, the first effect is a price spike in petrochemical feedstocks and finished polymers. The second effect — which takes weeks rather than days to materialise — is supply tightness in the products made from those polymers. Plastic packaging. PVC pipes. Synthetic textiles. Agricultural films used in farming. Automotive components. Medical equipment. The list of industries that use polymer inputs is essentially a list of modern manufacturing.

Petrochemical plants in India, China, South Korea, Japan and Southeast Asia that rely on Gulf naphtha imports are already beginning to feel feedstock constraints. Some are cutting run rates. Others are seeking alternative feedstock sources at significantly higher prices. The cost increase will eventually appear in the products those plants make — but with a lag of weeks to months that means most consumers will not connect the price of a plastic bottle or a synthetic fabric to a closed strait in the Persian Gulf.

Fertilisers: The Food Supply Link

The IEA’s warning about LPG and naphtha feeds directly into a concern that extends beyond energy markets into food security. Ammonia — the basis of nitrogen fertilisers that support roughly half of global food production — is manufactured using natural gas as its primary feedstock. Gulf natural gas, like Gulf LPG and naphtha, is caught behind the same closed chokepoint.

India’s fertiliser industry, which is heavily import-dependent for both finished fertilisers and the feedstocks to make them, is directly exposed. CLSA flagged in a separate note this week that fertiliser producers face output impact from the LPG and gas supply disruption. With the Rabi harvest approaching and Kharif sowing season not far behind, any sustained constraint on fertiliser availability or a sharp price spike in fertiliser inputs creates a food production risk that sits several steps downstream from the oil market but is ultimately driven by the same closed strait.

The Glass, Ceramics and Restaurant Economy

The IEA report’s cascade logic applies to sectors that most oil market commentary ignores entirely. CLSA’s India-focused energy note, released separately on the same day as the IEA report, identified specific industries facing output impact from the gas and LPG shortage: fertilisers, petrochemicals, restaurants, glass and ceramics.

Glass manufacturing requires sustained high-temperature furnaces that run on natural gas. Ceramics production — tiles, sanitaryware, industrial ceramics — uses the same. These are not marginal industries. India is one of the world’s largest producers and exporters of ceramic tiles, and the sector is heavily concentrated in Gujarat where gas supply disruptions are already being felt. A sustained gas shortage does not just raise input costs for these industries. It threatens their ability to run production lines at all, since glass and ceramic furnaces cannot simply be turned off and restarted without significant technical and financial cost.

Restaurants are the most visible and immediate casualty. India has approximately 7.5 million food service establishments, the overwhelming majority of which run on commercial LPG. A sustained shortage at the commercial cylinder level does not just raise costs — it forces closures, reduced operating hours and menu restrictions that flow directly into food delivery order volumes, as Motilal Oswal flagged in its note on Swiggy and Eternal on Thursday.

Why This Cascade Is Different From a Normal Price Shock

In a normal oil price spike — the kind driven by OPEC production decisions or demand surges — the mechanism is price. Inputs get more expensive, margins compress, prices rise, demand adjusts. That is uncomfortable but manageable.

The current cascade is different because for many of these downstream users, the problem is not just price. It is physical availability. You cannot run a restaurant on expensive LPG if there is no LPG to buy at any price. You cannot run a petrochemical plant on expensive naphtha if naphtha is not being shipped because no tanker will transit the Strait. A price shock allows adjustment over time. A physical supply shock forces immediate operational decisions — shut the line, switch the fuel, find an alternative, or close.

The IEA’s March report, released on March 12, is the first authoritative global assessment to formally document that the cascade has begun. LPG shortage in India and East Africa is not a local distribution problem. It is a direct consequence of the world’s most important oil chokepoint being effectively closed, and it connects the cooking gas in an Indian household directly to a war that started on February 28 — thirteen days ago.

The speed of that transmission from geopolitical event to kitchen shelf is the clearest illustration yet of how deeply the global energy system is threaded through daily life, and how quickly it unravels when the thread is pulled.
