Key highlights:
World’s most important oil chokepoint linking the Persian Gulf to the Arabian Sea
Handles ~20% of global oil and LNG trade
Disruptions have triggered oil price spikes and global economic impact
India heavily dependent for crude oil, LNG, and LPG imports
Tensions and blockades due to Iran and Israel war threaten energy security, especially for Asia
Why in News?
The ongoing conflict in West Asia between US, Iran and Israel has prompted Iran to block the Strait of Hormuz.
This has led to disruption in maritime movement through the Strait of Hormuz raising concerns over global supply of oil and gas.
It has majorly impacted Liquefied Natural Gas (LNG) supplies to India.
What is the Strait of Hormuz?
The Strait of Hormuz is located between Iran in the north and Oman and the United Arab Emirates (UAE) in the south.
Its strategic location connecting the Persian Gulf with the Gulf of Oman and Arabian Sea has enabled it to become arguably the world’s most important maritime chokepoint.
While it is a relatively narrow passage for global shipping traffic, it plays a huge role in global energy trade.
More than 20% of the global share of oil and gas supplies are transported through the Hormuz Strait according to recent estimates.
Major oil producing countries in the Persian Gulf like Saudi Arabia, Iran, Iraq, Kuwait and Qatar rely on this passage to export their energy resources worldwide.
The introduction of missile batteries on nearby islands, tanker attacks, or mining could all disrupt shipping. In short, closure of the strait could swiftly spike oil and gas prices worldwide and strain global trade.

Location & Geography of Strait of Hormuz
The Strait of Hormuz’s location sits between Iran (north) and the Musandam Peninsula (south), an Omani/UAE exclave on the Arabian Peninsula.
It is about 104 miles long, narrowing to just ~21–24 nautical miles (39 km) at its tightest point.
Shipping lanes run through it: two one-way lanes (each ~2 miles wide) are separated by a small buffer zone.
On a world map one clearly sees how this narrow strait is the only sea outlet from the Persian Gulf to the open ocean.
The Iranian shore is mountainous and dotted with islands (e.g. Qeshm, Hormuz), while the Arabian (Oman/UAE) shore has cliffs and coves.
At the narrowest point the tanker lanes lie in Omani territorial waters, before entering Iranian waters.
This geography means Iran controls the north side and Oman the south, giving Iran leverage over the strait’s security.
Strategic Importance of Strait of Hormuz
Location & Geography: The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It lies between Iran to the north and Oman and the United Arab Emirates to the south. At its narrowest point, it spans approximately 21 nautical miles (39 km).
Global Energy Corridor: This strait serves as a critical conduit for global energy trade. In 2024–2025, an estimated 20 million barrels of crude oil and liquefied natural gas (LNG)-about 20% of the world’s daily consumption-transited through the Strait of Hormuz. Key oil producers, including Iran, Iraq, Kuwait, Saudi Arabia, Qatar, and the UAE, rely heavily on this route to reach international markets .
Economic Impact of Disruption: A closure of the Strait would have profound economic repercussions, particularly for Asian economies. Approximately 84% of crude oil and 83% of LNG passing through the strait are destined for Asia. For instance, nearly half of India’s crude oil, 60% of South Korea’s, and 75% of Japan’s imports come via this route. Disruptions could lead to fuel shortages, inflation, and hinder manufacturing sectors in these regions.
Historical Precedents: The Strait of Hormuz has been a focal point during periods of geopolitical tension. In mid-2019, attacks on tankers near the strait caused oil prices to spike by approximately 4% overnight. More recently, on June 13, 2025, Brent crude prices surged from $69 to $74 per barrel due to fears of a blockade. Analysts warn that a complete shutdown could drive prices to $120–130 per barrel, triggering global inflation .
Strategic Alternatives & Limitations: While alternative routes like Saudi Arabia’s East-West Pipeline and the UAE’s Fujairah pipeline exist, they collectively accommodate less than 15% of the total volume that transits through the Strait. Thus, a closure would significantly disrupt global energy supply chains .
Strategic Importance on the World Map: The Strait of Hormuz's location is pivotal in global trade and energy security. Its position as the only sea passage from the Persian Gulf to the open ocean underscores its strategic significance. Understanding its geography is essential for comprehending its impact on international relations and global markets.

Geopolitical Tensions
Recent escalations in the Israel-Iran conflict, including U.S. airstrikes on Iranian nuclear sites, have led to decline in commercial shipping traffic through the Strait of Hormuz by 95%
Over 1,000 cargo vessels, the majority of them oil and gas tankers, have been denied access to the strait of Hormuz as a result of the Israeli and US war against Iran.
Iran has attacked ships and has started laying mines in the strait, which has effectively closed the Strait of Hormuz passage for marine traffic.
Timeline of Key Events and Strategic Impacts on the Strait of Hormuz
Period | Event & Impact on Hormuz Strait |
1980–1988 | Iran–Iraq Tanker War • Over 100 tankers hit via missiles/mines in the Hormuz region • In 1984, ~30% of global oil shipments passed through the Hormuz Strait. • No full blockade; US & European escorts protected Gulf transit. |
April 18, 1988 | Operation Praying Mantis (US Navy) • Retaliatory strike against Iranian mining of USS Samuel B. Roberts. • Destroyed oil platforms & naval vessels, reinforcing Hormuz’s strategic security. |
Post-1988 | • Strait remained open—despite threats—because depth (60–100 m) and width (~21 nmi) make indefinite blockade impractical. |
Impact of Disruption on World
The halt of oil and gas shipments via the strait is a crisis scenario for the global energy system, and one of the biggest disruptions to the energy supply chain the world has ever seen.
There is no spare capacity elsewhere in the world that could replace the loss of oil from the Middle East.
As the supply of oil and gas is at risk, the disruption has triggered a spike in prices.
From a historical perspective, such geopolitical crises in the region have caused unprecedented increases in oil prices. For instance, the Russia-Ukraine war caused oil prices to go up to $125 per barrel.
Iranian authorities proposed that oil prices could rise to over $200 per barrel in the event of an escalation, and the United States' executive government referred to the price hike as a short-term effect of security measures in the region.
Impact on India’s energy security
The Hormuz Strait is critical for India’s energy security. India imports nearly 90% of its crude oil, and a large portion comes from Gulf states whose tankers sail through Hormuz.
In early 2025 about 2.0–2.1 million barrels per day of India’s oil (out of ~5.5 mbpd total) transited this corridor.
Overall, an estimated 53% of India’s crude in 2025 came from Gulf suppliers (like Iraq and Saudi Arabia).
Thus the disruption at Hormuz Strait directly threatens over one-third of India’s oil imports.
Qatar accounts for half of India’s imports of LNG. These imports provide half of India’s liquefied natural gas requirements.
A shortage of natural gas would affect various sectors of the Indian economy like fertiliser production, power generation, gas distribution and Industrial energy use.
The country depends on imports to meet 60% of its liquefied petroleum gas (LPG) requirements, and LPG is mainly supplied by the Gulf region before it reaches India, upstream of the strait of Hormuz.
The lack of LPG would have significant consequences on the availability of cooking gas.
Way forward: Response and mitigation
In recent years New Delhi has greatly increased oil imports from Russia (which bypasses Hormuz Strait via alternate routes) as well as the US and Brazil.
As India’s petroleum minister noted, a large share of India’s supplies “do not come through the Strait of Hormuz now”.
Moreover, India’s expanded strategic petroleum reserves (hundreds of days’ supply) provide a buffer against short-term shocks.
Nevertheless, Asia’s tight oil market means Indian refiners and consumers still feel a disruption.
India is currently exploring alternative sources of crude oil and LNG such as the United States, Russia and Australia to tackle the supply shortage.
More refineries are being encouraged to produce propane and butane. These are key components of liquefied natural gas (LNG).
India is also in discussions with the US asking them to provide maritime insurance support to the ships in the affected region.
Indian Prime Minister Narendra Modi has also reached out to Iranian President Masoud Pezeshkian voicing the concerns. He emphasized that India’s top priorities are the safety and security of Indian nationals, along with uninterrupted transit of goods and energy.
The Government of India has used its emergency powers under the Essential Commodities Act of 1955 to regulate natural gas supplies to ensure the supply of essential commodities to essential consumer segments.
