In global geopolitics, sometimes the biggest economic shock begins at the narrowest point on the map. The Strait of Hormuz, a thin stretch of water between Iran and Oman, is barely 33 km wide at its narrowest. Yet nearly one-fifth of the world’s crude oil passes through it every day. When tensions rise here, the ripple travels straight to petrol pumps, inflation charts and central bank policies across the world.
The escalation between the United States and Iran has once again turned this corridor into the centre of global energy anxiety. Oil prices have already surged past $100 per barrel, with market forecasts warning that prices could move toward $120–$150 if disruptions persist.
For India, the stakes are even higher. As the world’s third-largest oil consumer and one of the most import-dependent economies, developments in the Gulf directly shape inflation, currency stability and government finances.
Why the Strait of Hormuz matters so much
The Strait of Hormuz connects the Persian Gulf with the Arabian Sea and is the main route for oil shipments from countries such as Saudi Arabia, Iraq, Kuwait, Qatar and the UAE.
About 20% of the world’s daily oil supply flows through this passage.
For India specifically:
- Around 88-90% of crude oil demand is met through imports.
- Roughly 35-52% of India’s crude imports pass through the Strait of Hormuz.
- India imports about 5 million barrels of crude oil per day, a large share coming from the Gulf.
This means any disruption in this route instantly affects both supply certainty and global oil prices.
Markets have already reacted sharply. Brent crude has moved close to $120 per barrel, as shipping disruptions, production halts, and security concerns have stopped tanker movement through the region.
How higher crude prices hit India’s economy
Crude oil is not just another commodity for India. It sits at the base of multiple economic chains.
When oil prices rise, several things happen almost simultaneously.
1. Inflation starts creeping up
Crude oil feeds into petrol, diesel, LPG, aviation fuel and petrochemicals. These influence:
- transport and logistics costs
- food prices
- manufacturing inputs
- airline tickets
- electricity generation in some sectors
Higher fuel prices eventually push up retail inflation.
2. India’s import bill rises sharply
A $10 increase in crude oil prices can significantly increase India's annual import bill by billions of dollars. Since India imports most of its energy needs, higher oil prices widen the current account deficit.
3. Pressure builds on the rupee
More expensive oil means India needs more US dollars to pay for imports.
This often leads to:
- higher demand for dollars
- pressure on the rupee
- possible depreciation of INR
Historically, periods of oil spikes have coincided with rupee weakness, already trading near an all-time low.
4. Fiscal pressure on the government
The government now faces a policy balancing act.
When crude prices remain elevated, it often has to consider:
- cutting fuel taxes
- supporting oil marketing companies
- absorbing part of the price shock
Each of these has implications for fiscal balances.
Impact on key Indian industries
The oil shock is already beginning to ripple through multiple sectors.
Aviation
Jet fuel is one of the largest operating costs for airlines. Rising crude prices are pushing up aviation fuel costs and could eventually affect airline profitability and ticket prices.Jet fuel is one of the largest operating costs for airlines.

Logistics and transport
Diesel powers trucks, buses and freight transport. Higher diesel prices are increasing logistics costs across supply chains.Logistics and transportDiesel powers trucks, buses and freight transport. Higher diesel prices are increasing logistics costs across supply chains.
Chemicals and petrochemicals
Many petrochemical products rely on crude derivatives as raw material, and input costs are already rising for manufacturers.
Fertilizers and agriculture
Natural gas and petroleum products play a role in fertilizer production and irrigation. Any prolonged disruption affects fertilizer economics and farm input costs.Fertilizers and agricultureNatural gas and petroleum products play a role in fertilizer production and irrigation.

Textiles and synthetics

Some textile raw material prices have already risen as shipping disruptions begin to affect supply chains.Textiles and syntheticsPolyester and other synthetic fibres are derived from petrochemicals.

LNG risk: the lesser discussed problem
While crude oil dominates headlines, LNG has also emerged as a growing concern.
India imports large volumes of LNG from Qatar, and these shipments also pass through the Strait of Hormuz. If cargo movement stops or slows:
- gas supply to industries may be curtailed
- city gas distribution could face constraints
- power plants dependent on gas may face shortages
Some companies have already begun reducing gas supply to industrial consumers as shipments get disrupted.
How the RBI may respond
The Reserve Bank of India does not directly control oil prices, but it reacts to the economic effects of oil shocks.
Three possible responses emerge.
1. Managing rupee volatility: The RBI may intervene in forex markets to stabilize the rupee if depreciation becomes sharp.
2. Recalibrating interest rate expectations: If oil-driven inflation rises significantly, rate cuts may be delayed or the central bank may adopt a cautious stance.
3. Liquidity management: Fuel inflation can tighten financial conditions. The RBI may adjust liquidity through open market operations if required.
India’s buffer: strategic petroleum reserves
To manage supply disruptions, India has created Strategic Petroleum Reserves (SPR) located in:
- Visakhapatnam
- Mangaluru
- Padur
Combined with commercial inventories, India currently has around 74 days of oil cover, though this is still below the 90-day benchmark recommended globally.
However, some estimates suggest that immediately available reserves may only cover around 25 days of consumption in extreme disruption scenarios, depending on inventory drawdown and refinery operations.
This gives India time, but not indefinite protection.
Government’s playbook in such crises
India is already deploying several strategies to manage the shock.
Diversifying crude sources
Over the past few years, India has expanded imports from:
- Russia
- the United States
- Brazil
- West African countries
This diversification helps reduce reliance on a single region.
Strategic diplomacy: Energy diplomacy becomes critical during such crises. Temporary waivers for Russian oil purchases (the US has already allowed it) or new supply agreements can help stabilize imports.
Using reserves strategically: Strategic petroleum reserves can be released temporarily to smooth supply shocks.
Demand management: In extreme cases, gas supply to industries may be rationed to prioritize essential sectors.
The bigger question: how long can India manage?
If the disruption in the Strait of Hormuz remains limited and temporary, India can absorb the shock through reserves, diversified sourcing and market adjustments.
However, if tensions escalate and oil prices remain above $120 for an extended period:
- inflation would rise
- the rupee could weaken
- fiscal pressure would increase
- economic growth could slow
This is why energy security is becoming a central pillar of India’s economic strategy.
The unfolding story
The situation in West Asia has already begun affecting global energy markets.
Tanker movement through the Strait of Hormuz has slowed sharply as shipping companies pause routes amid security risks. Attacks on energy infrastructure and disruptions in Gulf exports have tightened supply, pushing Brent crude above $100 per barrel in recent trading sessions.
With nearly a fifth of global oil supply passing through this corridor, even partial disruption has been enough to rattle markets. Commodity prices have reacted quickly, and investors are now closely watching developments between Washington, Tehran and Gulf producers.
Conclusion
For India, the developments in the Middle East are no longer a distant geopolitical issue. Rising crude prices, shipping disruptions and tightening supply have already started reflecting in energy markets.
India has some buffers in the form of strategic reserves and diversified oil imports. But if disruptions in the Strait of Hormuz continue, the pressure could gradually spill into inflation, currency stability and policy decisions.
The episode is a reminder that in the global energy system, geography still plays a powerful role. And sometimes, the stability of large economies depends on whether a narrow sea route keeps functioning.
