If the Red Sea is blocked, Asia will face pressure from a "double choke point" in energy and trade

Overview

This report discusses the scenario in which Red Sea shipping is disrupted or blocked amid escalating tensions in the Middle East. Nomura notes that the Red Sea, Bab el-Mandeb Strait, Suez Canal, and SUMED pipeline remain critical channels for global energy flows and Asia-Europe trade; if the Strait of Hormuz is already blocked, further disruption in the Red Sea would create a 'double choke point,' exposing Asia to higher energy import costs, trade delays, and supply chain pressure.

Core views

The core view is: first, the Red Sea is not a peripheral route, as the Bab el-Mandeb Strait, Suez Canal, and SUMED pipeline still handle significant oil product and container volumes; second, Red Sea disruption would mainly affect crude oil and petroleum products, while LNG would be less affected; third, Asia, especially India, is highly sensitive to crude oil transported via the Red Sea and Suez system; fourth, electronics, auto parts, textiles, and some agricultural products in Asia-Europe trade could face higher freight rates and longer delivery times due to rerouting via the Cape of Good Hope; fifth, this scenario would increase the risk of stagflation in Asia.

Analysis framework

The report uses a shipping choke-point scenario analysis, comparing the Bab el-Mandeb Strait, the Suez Canal, the SUMED pipeline, the Strait of Hormuz, and the Cape of Good Hope, and combines EIA and shipping data to assess oil flows, cargo structure, destination distribution, alternative route costs, and the transmission channels to Asian imports and exports.

Methodology notes

• Geopolitics and shipping scenariosMaritime choke-point risk analysis

  Double choke point

  If Red Sea shipping is disrupted while the Strait of Hormuz is already blocked, the main channels for energy and cargo between the Middle East, Europe, and Asia would be constrained at the same time, amplifying supply tightness.

• Supply chain transmissionTransport cost and delivery-time shock

  Cape of Good Hope alternative route cost

  Rerouting via the Cape of Good Hope can ease blockade risk, but it adds around 12 to 15 days of sailing time, more fuel consumption, and higher freight rates, and may affect perishables and just-in-time delivery industries.

• Regional exposureAsia energy import exposure analysis

  India's dependence on the Suez and SUMED routes

  The report points out that most crude oil and condensate transported through the Red Sea system are destined for Asia, and India faces a more pronounced cost shock because a relatively large share of Russian oil is imported via the Suez route.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Asia crude oil and petroleum products imports

  Direct negative exposure

  Strengths

  Some supply pressure can be eased through alternative routes or pipelines.

  Weaknesses

  A simultaneous blockage of the Red Sea and Strait of Hormuz would significantly push up import costs and reduce supply flexibility.

  Comparison

  Compared with LNG, crude oil and petroleum products are more directly affected by Red Sea disruption.

  Risks

  Higher oil prices, freight rates, and insurance costs; larger energy import bills.

• India

  High-exposure region

  Strengths

  Some of the shock can be buffered through sourcing shifts and inventory buffers.

  Weaknesses

  It relies heavily on Russian oil transported via the Suez Canal.

  Comparison

  Among major Asian economies, India faces a more pronounced import cost burden.

  Risks

  Rising energy costs may intensify inflation and current account pressure.

• Asia exports to Europe

  Negative exposure along the trade chain

  Strengths

  Some cargo can be rerouted via the Cape of Good Hope or buffered by inventory arrangements.

  Weaknesses

  Longer transit times and higher freight rates weaken price competitiveness and delivery competitiveness.

  Comparison

  Compared with intra-regional trade, long-haul Asia-Europe trade is more exposed to disruptions on the Suez route.

  Risks

  Order delays, margin pressure, and greater supply chain delivery uncertainty.

• Automotive supply chain

  Indirect negative exposure

  Strengths

  The industry can buffer short-term disruption through inventory and alternative sourcing arrangements.

  Weaknesses

  The European auto industry depends on imports of Asian parts, and shipping delays may affect production rhythm.

  Comparison

  Auto parts are more sensitive to delivery times than ordinary low-urgency cargo.

  Risks

  Longer lead times, production cuts, and higher inventory costs.

• LNG transport

  Relatively low exposure

  Strengths

  The report shows Red Sea LNG flows have already declined due to security and insurance cost factors.

  Weaknesses

  If regional risks escalate further, insurance and route constraints could still have marginal effects.

  Comparison

  Compared with crude oil and petroleum products, LNG is less affected by Red Sea disruption.

  Risks

  Localized route risks and higher insurance costs.

• Container freight rates

  Upside risk

  Strengths

  Current freight rates are still at relatively low levels, leaving some room for near-term buffering.

  Weaknesses

  A blocked Red Sea would force rerouting via the Cape of Good Hope, raising fuel, time, and capacity-occupation costs.

  Comparison

  Similar to the Red Sea disruption seen since 2023, rerouting would push more traffic toward the Cape of Good Hope.

  Risks

  Freight rate rebound, delivery delays, and higher supply chain costs.

Key data

• Share of global seaborne traffic carried by Red Sea-related passagesabout 9%Refers to the share of global seaborne traffic accounted for by the Bab el-Mandeb Strait and the Suez Canal.
• Share of global container traffic carried by Red Sea-related passagesabout 20%This shows that the Red Sea is not only an energy corridor but also an important route for Asia-Europe cargo trade.
• Share of global oil supply carried by Red Sea-related passagesabout 8.7%Includes the Bab el-Mandeb Strait, the Suez Canal, and the SUMED pipeline.
• Total oil product flow through the Suez Canal and SUMED pipeline in 1H25about 4.9mbpdThe report cites EIA data, which is below the peak seen in 2023.
• Share of crude oil and condensate transported through the Red Sea system to Asiaabout 68%Asia is the main destination.
• Share of related crude oil and condensate flowing to India in 1H25close to 60%This reflects India's high exposure to this route.
• Additional sailing time via the Cape of Good Hopeabout 12 to 15 daysThis increases fuel costs, freight rates, and delivery uncertainty.

Impact & implications

For Asia, the impact of Red Sea disruption would be felt on both the import and export sides. On the import side, higher crude oil and petroleum product costs would increase pressure on energy importers, with India facing the most pronounced burden. On the export side, Asian exports to Europe in manufactured goods, auto parts, electronics, textiles, and some agricultural products could lose competitiveness as freight rates rise and shipping times lengthen. Europe's automotive industry dependence on Asian parts imports could also cause delivery delays and even production cuts. Overall, this scenario would increase the risk of stagflation in Asia.

Risks

• Further escalation in the Middle East and renewed Houthi disruption to Red Sea shipping.
• Simultaneous blockage of the Strait of Hormuz and Red Sea routes, creating a double shock to energy supply.
• Rerouting via the Cape of Good Hope leading to higher freight, fuel, and insurance costs.
• A sharp rise in import costs for Asian energy importers such as India.
• Longer delivery cycles in Asia-Europe trade and disruption to the automotive and electronics supply chains.
• Higher energy and transport costs increasing stagflation risk in Asia.

What to watch

• Commercial vessel traffic through the Red Sea, Bab el-Mandeb Strait, and Suez Canal.
• Whether Houthi-related attacks or threats escalate.
• Transit through the Strait of Hormuz and changes in Middle Eastern energy exports.
• The WCI container freight index and freight rates on the Shanghai-Europe route.
• Whether traffic on the Cape of Good Hope route continues to rise.
• India's crude oil import sources, costs, and the share routed via the Suez path.
• European auto industry parts inventories, delivery delays, and production adjustments.
