Why in the News ?

The second phase of the Iran–U.S. conflict has shifted from direct military confrontation to a strategic contest over the Strait of Hormuz, one of the world’s most critical maritime chokepoints.Disagreements over the governance, transit rules, and proposed toll mechanism for the strait have reignited hostilities, with significant implications for global energy security, international shipping, and West Asian geopolitics.

 

Background: Why the Strait of Hormuz Became the Core Issue

•     The Strait of Hormuz has emerged as the principal theatre of the second phase of the Iran–U.S. conflict.
•     After the June 2026 ceasefire, both countries signed a Memorandum of Understanding (MoU) intended to temporarily ease tensions.
•     The MoU provided that:

○       Iran would permit free passage of ships for 60 days.

○       Iran and Oman would jointly discuss the future administration of the Strait.

•     However, disagreements soon surfaced regarding:

○       Long-term governance.

○       Transit regulations.

○       Financial arrangements for shipping.

•     The collapse of negotiations transformed the dispute into a strategic maritime confrontation rather than a conventional military war.
• The conflict highlights how maritime chokepoints have become central to modern geopolitical competition.

 

Key points : Strait of Hormuz ●  Located between Iran and Oman. ●      Connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. ●      One of the world’s busiest maritime chokepoints. ●      Critical route for global crude oil and LNG trade. ●      Strategic importance for Asia, Europe and global energy markets. ●      Strait of Hormuz is among the world’s most strategically important maritime chokepoints. ●      Oman shares control of the southern side of the Strait, while Iran borders the northern side. ●      The dispute revolves around governance, transit rights, and maritime administration. ●      UNCLOS forms the principal legal framework governing international navigation through straits. ●  Maritime security in Hormuz has direct implications for global energy prices, international trade, and India’s energy security. Important International Organisations ●  International Maritime Organization (IMO) – UN agency responsible for maritime safety and shipping regulations. ●      Gulf Cooperation Council (GCC) – Regional political and economic grouping of Gulf Arab states. ●  International Maritime Information Center (JMIC) – Maritime security information-sharing mechanism. International Law Involved: United Nations Convention on the Law of the Sea (UNCLOS), 1982 ●  Guarantees Freedom of Navigation. ●      Provides for Transit Passage through international straits. ●      Coastal states cannot arbitrarily obstruct international navigation. ●  Transit passage differs from innocent passage by ensuring uninterrupted movement through international straits. Important Maritime Concepts ●  Freedom of Navigation ●      Transit Passage ●      Exclusive Economic Zone (EEZ) ●      Territorial Sea ●      Maritime Chokepoint ●  Sea Lines of Communication (SLOCs) Importance for India ●  A significant share of India’s crude oil imports passes through Hormuz. ●      Major LNG supplies originate from Gulf countries. ●      Large Indian diaspora resides in the Gulf. ●      Indian merchant seafarers regularly operate in the region. ●  Stable Hormuz navigation is essential for India’s energy and economic security.

 

Sequence of Events Leading to the Resumption of Hostilities

•     June 14, 2026: Iran and the United States agreed to a ceasefire.
•     A formal MoU was finalized providing temporary free navigation.
•     Iran subsequently established the Persian Gulf Strait Authority (PGSA) to regulate maritime transit.
•     The PGSA announced:

○       Mandatory passage permits.

○       Approved marine insurance.

○       Potential future transit fees.

•     The move effectively formalized Iran’s administrative role over the Strait.
•     International Maritime Organization (IMO), with Oman’s cooperation, introduced an alternative southern navigation corridor.
•     Iran viewed this move as undermining its authority.
•     Doha negotiations between Iran, Oman and the United States failed after Washington rejected proposals regarding future management of the Strait.
•     Following the diplomatic failure:

○       Iran resumed attacks on merchant vessels.

○       The United States reinstated sanctions and intensified maritime enforcement.

• The ceasefire gradually collapsed, leading to renewed confrontation.

Strategic Importance of the Strait of Hormuz

•     The Strait of Hormuz is among the world’s most critical maritime chokepoints.
•     It connects:

○       The Persian Gulf

○       The Gulf of Oman

○       The Arabian Sea

•     It serves as the principal export route for:

○       Crude oil.

○       Liquefied Natural Gas (LNG).

○       Petroleum products.

•     Major energy exporters dependent on the Strait include:

○       Saudi Arabia.

○       Iraq.

○       Kuwait.

○       Qatar.

○       United Arab Emirates.

○       Iran.

•     Any disruption results in:

○       Higher oil prices.

○       Increased freight costs.

○       Global supply chain disruptions.

○       Energy market uncertainty.

•     For India, uninterrupted navigation through Hormuz is vital because:

○       A significant share of crude oil imports originates from the Gulf.

○       LNG imports depend on safe maritime passage.

○   Indian seafarers are employed extensively on international merchant vessels.

Major Areas of Disagreement Between Iran and the United States

•     Iran sought recognition of its role in administering the Strait.
•     Proposed:

○       A voluntary transit toll inspired by the Malacca–Singapore model.

○       Joint management with Oman.

•     The United States opposed:

○       Any transit fee.

○       Iranian administrative authority.

○       Changes to the existing international navigation regime.

•     Gulf Cooperation Council (GCC) countries also opposed Iranian control.
•     The United States argued that accepting tolls in Hormuz could create similar demands in:

○       Bab-el-Mandeb.

○       Suez.

○       Other strategic waterways.

•     Iran regarded alternative shipping corridors as politically unacceptable and strategically threatening.
•     The disagreement reflects competing interpretations of:

○       Maritime sovereignty.

○       Freedom of navigation.

○   International maritime law.

Escalation of Maritime Security Risks

•     Iran resumed attacks on commercial vessels after negotiations failed.
•     Several merchant ships came under attack.
•     The DFS Galaxy was attacked, resulting in the death of an Indian seafarer.
•     Iran also targeted major LNG carriers.
•     The United States intensified:

○       Maritime patrols.

○       Enforcement of sanctions.

○       Blockade measures against Iranian oil exports.

•     The Islamic Revolutionary Guard Corps (IRGC) continued threatening international shipping.
•     Maritime insurers increased risk premiums.
•     Shipping companies delayed voyages through the Strait.
•     Greek-operated LNG tankers postponed transit because of elevated risks.
