Why in the news
West Asia is witnessing another sharp rise in tensions after reports suggested that Iran has asked Yemen’s Houthi rebels to remain ready to disrupt shipping in the Red Sea if the United States targets Iran’s power infrastructure. According to a Reuters report citing multiple sources, the Houthis have reportedly deployed missiles and drones near the Bab el-Mandeb Strait and are awaiting orders.The development assumes greater significance because Iran has already shut the Strait of Hormuz following the recent escalation in its conflict with Israel and the United States. With a substantial share of Gulf oil now being rerouted through Saudi Arabia’s Red Sea pipeline to the port of Yanbu, any disruption in the Red Sea could affect one of the world’s last major energy corridors.Security analysts have warned that if the conflict spreads to the Red Sea, it could trigger another global energy and shipping crisis, similar to the disruptions witnessed during the Gaza conflict when several shipping companies avoided the route.
The concept in simple terms
The Red Sea is one of the world’s most important waterways. It lies between northeast Africa and the Arabian Peninsula and connects Europe with Asia through the Suez Canal.For centuries, it has been one of the busiest trade routes in the world. Every day, thousands of ships carrying crude oil, liquefied natural gas (LNG), food grains, manufactured goods and consumer products pass through the Red Sea.The southern entrance to the Red Sea is the Bab el-Mandeb Strait, a narrow passage between Yemen on one side and Djibouti and Eritrea on the other. Ships entering or leaving the Red Sea must pass through this strait.The northern end of the Red Sea connects to the Mediterranean Sea through the Suez Canal in Egypt. Together, the Bab el-Mandeb Strait and the Suez Canal form one of the shortest sea routes linking Asia and Europe.If this route is blocked, ships have to travel around the Cape of Good Hope at the southern tip of Africa. This alternative route is much longer, increases fuel costs, delays cargo deliveries and raises shipping charges worldwide.
How it works
The Red Sea as a global trade corridor. The Red Sea is an essential link in global maritime trade. Its strategic importance comes from three major factors:1. Energy transportationA significant portion of the world’s oil and natural gas passes through this route. After Iran closed the Strait of Hormuz, Saudi Arabia diverted a large share of its crude exports through pipelines leading to the Red Sea port of Yanbu. Reports suggest that the Red Sea now carries nearly 7% of global energy supplies.If shipping through the Red Sea is disrupted, oil exports from Saudi Arabia and other Gulf countries could be severely affected.2. International shippingThe Red Sea is one of the busiest commercial shipping lanes. Container ships transporting electronics, automobiles, machinery, food products and consumer goods between Europe and Asia rely heavily on this route.During previous Houthi attacks on commercial vessels in 2023-24, many shipping companies diverted vessels around Africa. The longer journey increased transportation costs and caused delays in global supply chains.3. Strategic military importanceThe Red Sea is equally important from a security perspective. Several countries, including the United States, France, China and Japan, maintain military facilities near the region to protect maritime trade.Control over the Bab el-Mandeb Strait provides significant strategic leverage because even small attacks on commercial vessels can disrupt global shipping.Analysts point out that the narrow nature of the strait makes it vulnerable. Even limited attacks using drones, missiles, or small boats can force shipping companies to suspend operations temporarily.
Why is the latest warning significant?
The Strait of Hormuz has traditionally handled around one-fifth of global oil supplies. Following its closure, Saudi Arabia shifted a large portion of its exports to the Red Sea route.If the Bab el-Mandeb Strait is also disrupted, both of the Middle East’s major oil export corridors would face simultaneous pressure.Such a situation could:
- Increase global crude oil prices
- Raise transportation and insurance costs
- Delay international trade
- Trigger inflation across many countries
- Affect energy security worldwide
Important institutions, laws or treaties
Suez Canal Authority (SCA)Manages and regulates traffic through the Suez Canal, one of the world’s busiest shipping routes.United Nations Convention on the Law of the Sea (UNCLOS)Provides the legal framework governing international navigation, maritime boundaries and freedom of navigation through international waters and strategic straits.Combined Maritime Forces (CMF)A multinational naval partnership that conducts maritime security operations in the Red Sea, Gulf of Aden and nearby waters.Operation Prosperity GuardianA US-led multinational initiative launched to safeguard commercial shipping in the Red Sea against attacks.
India angle
The Red Sea is strategically important for India because a large share of India’s trade with Europe, North Africa and parts of North America passes through the Suez Canal.Any disruption in the Red Sea can have multiple consequences for India:
- Higher crude oil prices may increase India’s import bill.
- Freight and insurance costs for exporters and importers could rise.
- Delivery of goods to Europe may be delayed.
- Inflationary pressures could increase if shipping costs remain elevated.
- Indian naval deployments may increase to protect merchant vessels operating in the region.
India has previously deployed naval ships in the Gulf of Aden and the Red Sea to safeguard commercial shipping against piracy and regional security threats.
