ABOUT STRAIT OF HORMUZ
Feature |
Details |

Between Iran (north) and Oman & UAE (south) |
Width |
~50 km at entrance; ~33 km at narrowest point |
Function |
Connects Persian Gulf to Gulf of Oman and Arabian Sea |
Legal Status |
Lies within territorial waters of Iran and Oman |
Importance |
World’s busiest oil transit chokepoint |
Volume of Trade |
~20 million barrels/day (~20% of global oil supply) |
Annual Value |
~$600 billion in oil and gas trade (U.S. EIA estimate) |
Main Exporters |
Iran, Iraq, Saudi Arabia, UAE, Kuwait, Qatar |
Main Importers |
India, China, Japan, South Korea |
WHAT COULD HAPPEN IF THE STRAIT IS CLOSED?
1. Oil Prices Could Surge
- Oil prices may jump from $77 to $120–$150 per barrel.
- This would raise fuel costs globally and affect domestic inflation in many countries.
2. Stock Markets and Trade Would Suffer
- Global stock markets may react negatively due to uncertainty.
- Central banks could revise inflation and interest rate outlooks.
3. Global Supply Chains Will Be Affected
- Increased shipping times (10–14 days longer via Cape of Good Hope).
- Higher freight and insurance costs, especially for oil shipments.
4. Higher Costs for Manufacturing Countries
- Countries like India, China, Japan, and South Korea will face higher energy and manufacturing costs.
- These costs will be passed on to consumers, increasing global inflation.
IMPACT ON INDIA
India’s Oil Dependency
- India imports ~88% of its crude oil needs.
- India consumes ~5.5 million barrels per day (bpd).
- 1.5 to 2 million bpd comes through the Strait of Hormuz.
- ~4 million bpd comes via other global routes.

WHAT DID INDIA’S OIL MINISTER SAY?
Minister Hardeep Singh Puri (June 23, 2025):
- “We have diversified our oil sources in the past few years.
- A large volume of our supplies no longer come through the Strait of Hormuz.
- Our Oil Marketing Companies have supplies for several weeks and continue to receive energy through several routes.”
The Minister also:
- Held a high-level security review with officials from the Navy, Coast Guard, ONGC, and Defence Ministry.
- Reaffirmed the government’s commitment to ensure uninterrupted fuel supply.
HOW COULD IRAN BLOCK THE STRAIT?
Method |
Description |
Naval Mines |
Laid using submarines or small attack boats |
IRGC Fast Boats |
Swarm attacks using speedboats with anti-ship missiles |
Submarine Warfare |
Attacks on commercial or military vessels using submarines |
Semi-submersibles |
Hard-to-detect vessels targeting oil tankers |
Historical Reference: In the 1980s,
during the Iran–Iraq war, similar tactics led to the
"Tanker War" where both nations attacked commercial oil shipments.
U.S. Response:
- Fifth Fleet is stationed in Bahrain.
- Past success: Operation Earnest Will (1987–88) safely escorted Kuwaiti oil tankers.
WILL IRAN ACTUALLY CROSS THE STRAIT?
Factor |
Explanation |
Loss of Own Oil Revenue |
Iran earns ~$67 billion from oil exports (FY 2024–25) |
China is a Key Buyer |
China buys ~90% of Iranian oil – would be negatively impacted |
Diplomatic Isolation |
Gulf countries (Saudi Arabia, UAE) may turn hostile |
U.S. and Allied Response |
Risk of direct military conflict |
Gulf Normalization Setback |
Iran’s recent regional diplomacy could collapse |
ARE THERE ANY EXPORT ROUTES?
Country |
Pipeline Name |
Capacity (approx.) |
Saudi Arabia |
East–West Pipeline (Petroline) |
5 million barrels/day |
UAE |
Habshan–Fujairah Pipeline |
1.5 million barrels/day |
Iran |
Goreh–Jask Pipeline |
~350,000 barrels/day |
Limitation: These
can handle ~3.5 million bpd, while the Strait handles
~20 million bpd.
