India’s exposure to imported energy has eased, but that improvement has done little to reduce its dependence on overseas crude oil. The country met 90% of oil demand with imports, while its maximum reserves cover only eight days of national consumption, according to a joint Confederation of Indian Industry and EY report. Those figures describe two different parts of the energy picture: dependence across primary energy sources is declining, while the oil system remains reliant on external supply. The distinction matters because a broad improvement can obscure a narrower vulnerability.
Broader energy dependence is falling
India’s reliance on imported primary energy declined from 47% in financial year 2017 to about 42% in FY25. The report describes this as gradual diversification, but the improvement hasn’t extended to crude oil: rising demand and lower domestic output have kept imports central to the supply mix. A lower aggregate share can indicate that the energy mix is changing, yet it doesn’t mean every major fuel has become less exposed to external supply. The composition of imports matters as much as the headline percentage.
That gap matters for refiners and the wider economy. Refineries need a steady flow of crude to keep operating, and disruptions can force buyers to search for replacement supplies under less predictable conditions. The effects can travel beyond the immediate purchasing decision, since oil is a key input across transport and industrial activity. The report’s figures don’t quantify those potential costs, but they show why a high import share is a matter of economic resilience as well as supply planning.
As one of the world’s largest crude importers, India remains exposed when shipments are disrupted or delivery routes become uncertain. The practical issue isn’t simply whether oil is available somewhere in the global market; buyers also need to secure cargoes, arrange delivery and manage the time before replacement supplies arrive. Similar import-dependent systems typically rely on a mix of supplier options, transport routes and stocks to manage that gap. Each can help, though none removes the underlying dependence on external barrels.
Supply disruption puts storage in focus
Disruptions to Middle Eastern flows during the Iran war and the Strait of Hormuz crisis pushed Indian buyers to seek alternative barrels. Record purchases from Russia and continued buying from West Africa helped replace some lost supply, but those moves don’t address the limited buffer held in reserve. Finding another seller can keep supplies moving, yet it’s not the same as having oil already stored and available for use. The distinction becomes sharper when disruption affects shipping or when multiple buyers compete for alternative cargoes.
Here’s the thing: a short reserve window leaves less room to absorb delays while supply arrangements change. Storage can provide time, but it can’t by itself replace production or guarantee that incoming shipments will arrive on schedule. This is more significant than it looks. The import share shows how much oil must come from abroad; the reserve figure speaks to how long the system can rely on stored supply if flows are interrupted.
State-owned Oil and Natural Gas Corporation plans to build a storage site at Mangaluru with capacity for about 13 million barrels. The project reflects a push to hold more commercial and strategic stocks after recent supply shocks exposed the constraints of India’s existing reserve capacity. Its stated capacity gives a sense of the proposed addition, but the source doesn’t say when it will be completed or how it would change the country’s days of cover. That distinction matters: announced capacity is a plan, while usable protection depends on a facility being built, filled and available when needed.
And this is the part most people overlook: storage is useful only as part of a broader supply system. Stocks can cushion an interruption, while alternative suppliers can help restore normal flows; each addresses a different point of failure. Neither approach makes the underlying import dependence disappear. A larger reserve may improve flexibility, but the available figures don’t establish how much disruption it could withstand.
Import exposure remains the key constraint
For India, the headline improvement in overall energy dependence masks a more difficult oil picture. With nine barrels in ten sourced abroad and current reserves covering just eight days of demand, the country’s ability to manage another interruption depends on both alternative supply and expanded storage. The report’s figures suggest that the key question isn’t only whether import dependence is falling in aggregate, but whether the most exposed fuel has enough room to absorb shocks. On crude, the evidence points to a thin buffer.
If you’re working in this space, the useful signals to watch are whether planned storage becomes available and whether buyers can continue to source oil from a range of suppliers when flows are disrupted. The facts given here don’t establish how quickly either capacity will change. That said, the pressure point is already clear: India has made progress in reducing its broader primary-energy import reliance, yet crude oil remains tied closely to overseas supply.
Eight days. That’s the reserve cover reported today, and it puts the scale of the challenge in plain terms.
