Discuss the significance of major straits of the world for global trade. Why is West Asia's instability a concern for India?

Straits are narrow natural waterways that join two larger seas. Article 38 of UNCLOS says ships crossing them have a right of transit passage, "which shall not be impeded" [1]. Most of the world's seaborne trade passes through a few such chokepoints. Hormuz in West Asia is currently the most fragile of them.

Significance of major straits for global trade

• Energy artery: About one-fifth of the world's oil and gas passes through the Strait of Hormuz [2]. So does roughly one-third of internationally traded fertilisers [3].
• East–West corridors: Malacca–Singapore links the Indian Ocean to East Asian manufacturing hubs. Bab-el-Mandeb and the Suez Canal link Asia to Europe. Gibraltar and the Bosporus carry Mediterranean and Black Sea energy and grain.
• Cost and time: Straits give the shortest routes. When one is disrupted, ships must take long detours such as the Cape of Good Hope, which raises freight and insurance costs.
• Leverage for coercion: At the UN Security Council, the IMO chief said there is "no legal basis" for tolls in Hormuz, and members rejected using straits as "bargaining chips" [3].
• Governance gap: In 2026, China and Russia vetoed a draft resolution from the Gulf states on shipping safety in Hormuz [4].

Why West Asia's instability concerns India

• Energy security: India imports about 88% of the crude oil it needs [5], much of it from the Gulf through Hormuz.
• Thin buffer: India's Strategic Petroleum Reserves hold 5.33 MMT at Visakhapatnam, Mangaluru and Padur. That is only about 9.5 days of crude requirement [6].
• Macroeconomy: Oil price spikes widen the current account deficit, push up inflation and weaken the rupee.
• Diaspora: The Gulf hosts a large part of the Indian diaspora. Conflict puts remittances at risk and can force costly evacuations.
• Connectivity: Conflict stalls projects such as Chabahar–INSTC and disrupts the Red Sea route that carries India's exports to Europe.

Straits are shared global commons, so a crisis in one region spreads into trade everywhere. India should keep diversifying its oil suppliers and expand its reserves, including the planned 6.5 MMT Phase-2 facilities at Chandikhol and Padur [7]. It should also keep up naval escort missions and support UNCLOS-based freedom of navigation through balanced diplomacy in West Asia. This would protect its energy security in line with SDG 7.
