Red Sea crisis explained: How a closure could disrupt global trade, spike shipping costs and fuel inflation

The Red Sea is not just a regional shipping lane; it is one of the most heavily trafficked arteries of global trade. Linking the Mediterranean Sea to the Indian Ocean via the Suez Canal and Bab-el-Mandeb Strait, it handles around 12–15 per cent of global trade volumes, 25–30 per cent of container shipping, 12 per cent of seaborne oil, and nearly 8 per cent of LNG and global grain trade.

In practical terms, this translates into tens of thousands of vessels annually, with the Suez Canal alone seeing over 21,000 ship transits a year, averaging close to 60 ships daily. A closure would therefore disrupt not just one route but also a substantial share of the world’s trade flows.

The geography of disruption

If the Red Sea were shut, ships moving between Asia and Europe would be forced to reroute around the Cape of Good Hope. This diversion adds roughly 3,500 to 4,000 nautical miles to a typical Asia-Europe journey and increases transit time by 10 to 15 days.

The economic impact of this delay is magnified by the scale of traffic involved; around 40 per cent of Asia-Europe trade and more than 95 per cent of vessels on this route typically pass through the Red Sea. The rerouting would effectively redraw global shipping maps, creating longer, costlier, and less efficient trade corridors.

A measurable supply shock

The most immediate consequence of closure would be a contraction in effective shipping capacity. According to estimates by J.P. Morgan, rerouting ships around Africa increases transit times by roughly 30 per cent, which translates into an approximate 9 per cent reduction in global container shipping capacity. This is equivalent to removing a significant portion of the global fleet’s efficiency without physically reducing the number of ships.

This “capacity squeeze” has already shown real-world effects. Several European auto manufacturers have reported production disruptions due to delays in receiving components from Asia. Industries dependent on just-in-time logistics, such as automotive, electronics, and machinery, are particularly vulnerable to such timing shocks.

Shipping costs respond sharply to disruptions in capacity and route efficiency. During recent Red Sea tensions, container freight rates surged dramatically. According to J.P. Morgan, spot rates on Asia-Europe routes increased nearly fivefold, while rates from China to the US rose by more than 100–140 per cent in certain corridors.

At their peak, freight costs for a standard container from China to Northern Europe approached $6,000, before easing to around $4,500, according to the Kiel Institute for the World Economy. Even at these moderated levels, prices remain significantly above historical averages, indicating structural pressure on shipping costs.

Trade flows

The impact of disruptions is visible in shipping volumes. Daily container ship traffic through the Red Sea has fallen from over 100 vessels to around 40 ships at certain points, according to the Kiel Institute for the World Economy. This represents a decline of more than 50 per cent in traffic, reflecting the scale of rerouting.

At the same time, global shipping networks are adapting. The number of container ships deployed globally has slightly increased, with around 5,450 vessels at sea daily, as companies add capacity to offset longer routes. European ports initially saw a sharp drop in arrivals, around 25 per cent fewer ships in December and January, before recovering partially to a 15 per cent decline in February, suggesting gradual system adjustment.

The economic impact of a Red Sea closure would extend beyond shipping into broader macroeconomic variables. Higher freight costs, longer delivery times, and supply bottlenecks feed directly into inflation.

Sectors reliant on imported goods would face rising input costs, which are typically passed on to consumers. Energy markets are particularly exposed. With 12 per cent of global seaborne oil and 8 per cent of LNG trade passing through the route, any sustained disruption could tighten supply and increase price volatility. Similarly, delays in grain shipments could affect food prices, especially in import-dependent regions.

Regional and global spillovers

The effects of a Red Sea closure would not be evenly distributed. Europe, the Middle East, and parts of Africa would bear the brunt due to their reliance on this corridor. Countries like Egypt, which depend heavily on Suez Canal revenues, would face fiscal pressures, while trade-dependent economies could see reduced growth.

At the same time, some regions could see indirect gains.

Countries along alternative routes, including those near the Cape of Good Hope, may benefit from increased demand for refueling and logistics services. However, these gains would likely be outweighed by the broader inefficiencies introduced into global trade.
