US–Iran Conflict 2026: Why the Strait of Hormuz Matters for India’s Energy Security
The renewed military exchange between the United States and Iran on 2 September 2026 has once again pushed the Strait of Hormuz to the centre of global attention.
The United States said its latest strikes targeted Iranian Revolutionary Guard military infrastructure, including air-defence systems, radars, maritime assets and mine-laying capabilities. Iran responded with missile and drone attacks on American assets across parts of West Asia. The immediate military developments are important, but for India the larger concern lies elsewhere: energy security.
The Strait of Hormuz is one of the world's most important energy chokepoints. A prolonged disruption here can affect crude-oil and LNG supplies, freight rates, insurance costs and international energy prices within a very short period.
That makes today's development unusually important for UPSC students. In fact, UPSC Mains 2026 directly asked about the challenges to India's energy security and the measures needed to combine energy security with economic growth and sustainability. The present crisis gives students a live case study for answering exactly that question.
What happened on 2 September?
After a period of relative lull, direct US-Iran hostilities intensified again.
According to Reuters, the United States carried out strikes against Iranian military targets linked to the Islamic Revolutionary Guard Corps (IRGC), while Iran retaliated against US military assets in countries including Jordan, Bahrain and Iraq.
The escalation immediately increased anxiety in energy and financial markets.
Brent crude was trading at around $94–95 per barrel on 2 September, after rising sharply following the renewed fighting.
But the real issue is not simply today's oil price.
The bigger question is:
What happens if insecurity around the Strait of Hormuz continues for weeks or months?
For an energy-importing economy like India, that is where the risk becomes serious.
First understand the Strait of Hormuz
The Strait of Hormuz is a narrow maritime passage connecting the:
Persian Gulf → Gulf of Oman → Arabian Sea
It lies between:
Iran to the north
and
Oman's Musandam Peninsula to the south.
The US Energy Information Administration describes it as one of the world's most important oil transit chokepoints.
For UPSC, the geography is extremely important.
Do not confuse these straits
Strait of Hormuz
Persian Gulf ↔ Gulf of Oman
Bab el-Mandeb
Red Sea ↔ Gulf of Aden
Strait of Malacca
Indian Ocean ↔ South China Sea
Bosporus
Black Sea ↔ Sea of Marmara
These maritime chokepoints often appear in map-based and statement-based questions.
Why is Hormuz so important for global energy?
The answer is simple: an enormous quantity of energy passes through a very narrow waterway.
According to the US Energy Information Administration, during the first half of 2025 around 20.9 million barrels per day of oil moved through the Strait of Hormuz.
That was equivalent to roughly:
20% of global petroleum-liquids consumption
and around:
one-quarter of globally traded maritime oil.
The LNG story is equally important.
Around 11.4 billion cubic feet per day of LNG moved through Hormuz in the first half of 2025, accounting for more than 20% of global LNG trade.
Most of this energy moves towards Asia.
Around 89% of the crude oil and condensate passing through Hormuz in the first half of 2025 went to Asian markets.
China, India, Japan and South Korea together accounted for a large majority of those flows.
This is why a crisis in a narrow waterway thousands of kilometres away can quickly become an economic issue for India.
Has the Strait of Hormuz been completely closed?
No.
This distinction is important.
The current problem is severe disruption and heightened risk, not necessarily a complete stoppage of every vessel.
Shipping data reported on 2 September showed only four commodity vessels transiting the Strait, compared with a ten-day average of around 13.
At the same time, flows have not fallen to zero. US Energy Secretary Chris Wright said around 17 million barrels of oil passed through Hormuz on Monday, indicating that significant oil movements were still possible despite the conflict.
So students should avoid exaggerated statements such as:
“The Strait of Hormuz has completely stopped functioning.”
A more accurate description is:
Traffic has become severely disrupted, unpredictable and much more expensive and risky.
Why can even partial disruption raise prices?
Oil markets respond not only to actual shortages but also to the risk of future shortages.
Suppose tankers can still pass through Hormuz, but:
- insurers raise war-risk premiums,
- shipping companies delay voyages,
- vessels require additional security,
- ports face uncertainty,
- tanker availability declines,
- or companies fear attacks.
The delivered cost of energy can still rise sharply.
Therefore:
Geopolitical risk → higher insurance + freight + supply uncertainty → higher energy prices
even before physical supplies completely stop.
LNG shows how serious the problem can become
The impact is particularly visible in LNG trade.
Reuters reported that Qatari and UAE LNG cargoes have used unusual ship-to-ship transfers outside the Strait of Hormuz to keep some supplies moving.
One such transferred cargo was subsequently delivered to India.
Ship-to-ship transfer means LNG is moved from one vessel to another at sea rather than following the normal shipping pattern.
This is technically complex and is not the normal way most LNG cargoes are transported.
The fact that companies are using such arrangements shows how seriously the conflict is disrupting normal energy logistics.
Asian spot LNG prices were reported at around $23.20 per mmBtu, more than double their pre-conflict levels.
Why is Qatar especially important?
Qatar is one of the world's largest exporters of LNG.
Most of Qatar's LNG export terminals lie inside the Persian Gulf.
For cargoes to reach India, Japan, South Korea or other major Asian markets by sea, they normally have to cross the Strait of Hormuz.
This means that even if India diversifies its crude oil imports, gas and LPG can remain vulnerable to disruptions around Hormuz.
That distinction is very important.
How exposed is India?
India remains heavily dependent on imported energy.
Petroleum Planning and Analysis Cell data for 2024–25 placed India's crude-oil import dependence at roughly 88%.
This means changes in international crude prices have a direct bearing on the Indian economy.
However, India has also been actively reducing its direct dependence on Hormuz-based crude routes.
During the earlier phase of the West Asian crisis in March 2026, the Petroleum Ministry said around 70% of India's crude imports were being routed outside the Strait of Hormuz, compared with roughly 55% earlier.
That diversification provides an important buffer.
But it does not make India immune.
LPG remains a bigger vulnerability
The same government briefing showed why India's energy-security problem cannot be understood through crude oil alone.
India imports roughly 60% of its LPG consumption, and about 90% of those LPG imports were then coming through the Strait of Hormuz.
LPG is directly connected with household energy security.
A disruption therefore affects not only refineries and industries but potentially cooking-fuel supply and government subsidy calculations.
This makes the Hormuz crisis both:
a strategic issue
and
a household-economy issue.
How higher crude prices affect India
The economic transmission can be understood step by step.
1. Import bill rises
India buys most of its crude oil from abroad.
If the price of each barrel rises, India has to spend more foreign exchange to buy roughly the same quantity.
So:
Higher crude price → higher petroleum import bill
2. Trade deficit can widen
Crude oil is one of India's largest imports.
If its value rises sharply while exports do not increase by the same amount, India's merchandise trade deficit can widen.
3. Current Account comes under pressure
A wider merchandise trade deficit can place pressure on India's Current Account Deficit, though the final outcome also depends on services exports, remittances and other flows.
This is why global oil prices matter to India's external-sector stability.
4. Rupee can come under pressure
Indian oil companies need dollars to purchase crude.
When the dollar demand associated with oil imports rises, it can place downward pressure on the rupee, especially if foreign capital flows are also weak.
A weaker rupee then makes dollar-priced oil even more expensive.
This can create a feedback loop:
Oil price rises → dollar demand rises → rupee weakens → imported oil becomes still more expensive
5. Imported inflation can increase
Oil enters the economy through much more than petrol and diesel.
Higher energy costs affect:
- road transport,
- aviation,
- shipping,
- agriculture,
- manufacturing,
- plastics,
- chemicals,
- logistics,
- and electricity generation in some sectors.
Businesses may eventually pass part of these higher costs to consumers.
This produces what economists call imported inflation.
6. Fertiliser costs can also be affected
Natural gas is an important feedstock for fertiliser production, especially urea.
If LNG and natural-gas prices rise sharply, fertiliser production becomes more expensive.
The government may then face a difficult choice between:
- allowing higher prices,
- increasing subsidies,
- or absorbing some costs through other mechanisms.
Therefore, West Asian energy disruption can indirectly affect agriculture and food prices as well.
7. Government finances may face pressure
Higher global fuel prices do not automatically mean that Indian retail prices must rise by exactly the same percentage.
The government can use measures such as:
- excise-duty changes,
- subsidies,
- supply-management measures,
- or other fiscal interventions.
But such actions have a cost.
If taxes are reduced, revenue may decline.
If subsidies rise, expenditure can increase.
Therefore, a prolonged oil shock can create a fiscal policy dilemma.
8. Growth can slow
High energy prices increase costs across the economy.
Transport becomes more expensive.
Industries face higher input costs.
Consumers may have less money left for other purchases.
Inflation can constrain monetary-policy choices.
The result can be:
higher inflation + weaker consumption + lower investment confidence
which is a difficult combination for any economy.
India is more prepared than it was earlier
It would also be wrong to present India as helpless.
India has spent years diversifying its petroleum suppliers.
The Petroleum Ministry said earlier in 2026 that Indian companies had access to crude and petroleum supplies that do not need to transit the Strait of Hormuz.
India can source crude from regions such as:
- Russia,
- the Americas,
- Africa,
- and suppliers whose export terminals lie outside the Persian Gulf.
This diversification means a Hormuz disruption does not automatically stop India's crude supply.
But alternative supplies may still become more expensive if global oil prices rise.
That is the key distinction:
Physical availability may remain manageable while affordability becomes difficult.
Are there alternative routes around Hormuz?
There are some alternatives, but their capacity is limited.
Saudi Arabia operates the East-West Pipeline, which can move crude from eastern oil-producing regions towards the Red Sea.
The UAE also has pipeline infrastructure connecting Abu Dhabi's producing areas with Fujairah, outside the Strait of Hormuz.
According to the EIA, these alternative Saudi and UAE routes could provide around 4.7 million barrels per day of bypass capacity.
Compare that with more than 20 million barrels per day that normally pass through Hormuz.
Clearly, pipelines cannot replace the Strait completely.
Strait of Hormuz vs Bab el-Mandeb
This is an excellent Prelims area.
Strait of Hormuz
Connects:
Persian Gulf → Gulf of Oman
Strategically important for:
- Gulf crude oil,
- Qatar LNG,
- Persian Gulf shipping.
Bab el-Mandeb
Connects:
Red Sea → Gulf of Aden
Strategically important for traffic moving towards:
- Suez Canal,
- Mediterranean Sea,
- Europe.
A vessel travelling from the Persian Gulf to India generally needs Hormuz.
A vessel travelling from the Indian Ocean towards the Suez Canal generally needs Bab el-Mandeb.
Why is the Musandam Peninsula important?
The southern side of the Strait of Hormuz is formed partly by the Musandam Peninsula.
Musandam belongs to Oman, even though it is geographically separated from the main territory of Oman by UAE territory.
This makes Musandam an exclave.
Prelims trap
The Strait of Hormuz is often casually described as being between Iran and the UAE.
Geographically, the narrow strategic passage is principally between:
Iran and Oman's Musandam Peninsula.
What is IRGC?
Another term appearing repeatedly in the current conflict is:
Islamic Revolutionary Guard Corps — IRGC
It is a powerful Iranian military and security organisation separate from Iran's regular armed forces.
It has important roles in:
- internal security,
- missile forces,
- regional military operations,
- and maritime security around the Persian Gulf.
The latest US strikes were described as targeting IRGC-linked military infrastructure.
For UPSC, remember the full form and its association with Iran.
Why does India's interest go beyond oil?
West Asian stability matters to India for several reasons.
Energy
The region remains important for:
- crude oil,
- LNG,
- LPG,
- petrochemicals.
Indian diaspora
Millions of Indians live and work across Gulf countries.
Regional conflict can therefore become a consular and evacuation challenge.
Remittances
Indian workers in Gulf countries are an important source of remittance inflows.
Trade
The Gulf is one of India's major trade regions.
Maritime routes
India's trade with Europe and parts of West Asia depends heavily on secure sea lanes.
Investment
Gulf sovereign wealth funds and companies have become increasingly important investors in India.
So India's interest is not simply:
“Keep oil flowing.”
It is much broader:
energy + diaspora + trade + shipping + investment + regional stability.
Why does India usually call for dialogue and diplomacy?
India has repeatedly argued that prolonged conflict in West Asia is not in its interest.
Earlier in the conflict, Prime Minister Narendra Modi told Parliament that major supplies of crude, gas and fertilisers reach India through the Strait of Hormuz and stressed that India supported dialogue and diplomacy to reduce tensions.
This position reflects practical national interests.
India has important relationships with:
- the United States,
- Iran,
- Israel,
- Saudi Arabia,
- UAE,
- Qatar,
- and other Gulf countries.
Taking an excessively rigid bloc position could reduce India's diplomatic room for manoeuvre.
India therefore generally tries to preserve strategic autonomy while supporting de-escalation and freedom of navigation.
What should India do to strengthen energy security?
The present crisis shows that energy security cannot depend on one solution.
India needs several layers of protection.
1. Diversify suppliers
India should avoid excessive dependence on a small number of countries or regions.
A wider supplier base reduces the effect of a regional disruption.
2. Diversify transport routes
Where possible, India should increase access to supplies that do not depend on vulnerable chokepoints.
The government's earlier move to route around 70% of crude imports outside Hormuz shows the value of this strategy.
3. Expand Strategic Petroleum Reserves
Strategic oil reserves provide emergency protection when normal imports are interrupted.
India should continue expanding reserve capacity and improve coordination between:
- strategic reserves,
- commercial inventories,
- refiners,
- and importers.
Strategic reserves cannot solve a very long crisis, but they can buy valuable time.
4. Diversify LNG sourcing
Gas supply needs its own strategy.
India should increase access to LNG from suppliers and terminals outside highly exposed routes while expanding domestic gas production where economically and environmentally viable.
5. Increase domestic exploration
Greater domestic oil and gas production can reduce import dependence at the margin.
India is unlikely to eliminate imports completely, but even a modest reduction improves resilience.
6. Accelerate renewable energy
Solar and wind energy do not require imported crude oil to generate electricity.
Expanding renewables therefore contributes not only to climate goals but also to strategic energy security.
But renewables need:
- storage,
- stronger grids,
- transmission capacity,
- flexible power systems.
7. Expand electric mobility and public transport
India's largest exposure to oil comes from transport.
Electric vehicles, railways, metros and public transport can gradually reduce oil demand.
This is one reason the energy transition has geopolitical value in addition to environmental value.
8. Green hydrogen and alternative fuels
Green hydrogen can eventually reduce imported fossil-fuel dependence in sectors such as:
- fertilisers,
- refining,
- steel,
- shipping.
Biofuels can also replace part of India's petroleum demand.
These technologies are not an immediate substitute during today's crisis, but they matter for long-term resilience.
9. Strengthen maritime security
Secure energy trade requires secure sea lanes.
India needs continued investment in:
- maritime-domain awareness,
- naval capability,
- merchant shipping,
- port resilience,
- coordination with partners,
- and protection of commercial vessels.
Energy security and maritime security are therefore closely linked.
Energy security is more than having enough oil
A useful way to remember energy security is through four ideas:
Availability
Is enough energy physically available?
Accessibility
Can India actually obtain and transport it?
Affordability
Can households and businesses pay for it?
Sustainability
Can the energy system remain viable environmentally and economically over the long term?
Today's Hormuz crisis primarily threatens:
accessibility + affordability
But India's long-term strategy has to address all four.
UPSC PYQ Connection — exceptionally strong
This current development has a direct connection with the UPSC Mains 2026 GS Paper III.
UPSC asked:
“Explain the key challenges for India's energy security. What measures do you suggest for ensuring energy security along with economic growth and sustainability?”
15 Marks | 250 Words
This means the present Hormuz crisis is not merely theoretically relevant to UPSC.
UPSC has just tested the exact theme.
Students preparing for future examinations should therefore remember this crisis as a contemporary example of:
- import dependence,
- geopolitical supply shocks,
- maritime chokepoints,
- energy diversification,
- strategic petroleum reserves,
- renewable energy,
- and strategic autonomy.
Prelims Focus

Mains-Ready Conclusion
The Strait of Hormuz illustrates one of the central realities of India's energy system: energy security begins far beyond India's borders.
A military clash in West Asia can raise the price of crude in India, affect the rupee, increase transport and fertiliser costs and complicate inflation management even when Indian refineries continue receiving enough physical oil.
India's diversification strategy has reduced some of this vulnerability, particularly for crude oil. But exposure through global prices, LNG, LPG and maritime trade remains significant.
The long-term solution is therefore not to search for one perfectly secure foreign supplier.
It is to build a more resilient energy system based on diversified imports, strategic reserves, secure sea lanes, domestic production, renewable energy, cleaner transport and sustained diplomacy.
The lesson from Hormuz is clear: for India, energy security is inseparable from economic security, maritime security and foreign policy.
