The Suez Canal

What Is the Suez Canal?

The Suez Canal is a 193-kilometer (120-mile) artificial waterway in Egypt that connects the Mediterranean Sea at Port Said to the Red Sea at Suez, providing the only direct maritime route between Europe and Asia without circumnavigating Africa.

The canal runs north-to-south across the Isthmus of Suez, crossing several natural lakes including the Great Bitter Lake and Lake Timsah, and accommodates two-way vessel traffic through a parallel channel built during the 2015 New Suez Canal expansion. With a depth of approximately 24 meters and a width that allows the world’s largest container ships and tankers to transit fully laden, it is the deepest and most heavily used artificial waterway in the world.

Operated by the Suez Canal Authority, an Egyptian state body, the canal carries roughly 12% of global maritime trade, 30% of global container traffic, and a significant share of seaborne energy flows between the Gulf, Asia, and European markets. Together with the Bab el-Mandeb Strait to the south, the Suez Canal forms the central spine of the Mediterranean-Red Sea-Indian Ocean shipping corridor.

Because the canal is the only practical alternative to a 10-to-14-day reroute around the Cape of Good Hope, any disruption to transit, whether mechanical, geopolitical, or security-driven, can produce immediate effects on global freight rates, container schedules, and energy supply chains.

Key Takeaways

• The Suez Canal is a 193-kilometer Egyptian waterway connecting the Mediterranean and Red Seas, providing the shortest maritime route between Europe and Asia.
• Roughly 12% of global trade, 30% of global container traffic, and 8 to 10% of seaborne oil pass through the canal under normal conditions, making it one of the world’s most important chokepoints.
• The canal is operated by the Suez Canal Authority, an Egyptian state body, with transit fees generating multi-billion-dollar annual revenue for Egypt.
• Disruptions in the Suez Canal, whether from grounding incidents, geopolitical conflict, or threats in the Red Sea, force vessels to reroute around the Cape of Good Hope, adding 10 to 14 days and significant fuel and insurance costs to each voyage.
• The Houthi attacks on Red Sea shipping that began in late 2023 cut Suez Canal traffic by more than 60% from pre-crisis levels, with traffic remaining 60% below 2023 levels through early 2026 despite the October 2025 Gaza ceasefire and the November 2025 Houthi cessation of attacks.

The Suez Canal Key Facts

Where the Suez Canal Is Located

The Suez Canal runs north-to-south through Egypt, crossing the Isthmus of Suez, the narrow strip of land that separates the African and Asian continents. The northern entrance is at Port Said on the Mediterranean coast, and the southern entrance is at Port Tewfik near the city of Suez on the Red Sea.

Along its route, the canal passes through several natural lakes that serve as wider holding areas for traffic, including Lake Manzala in the north, Lake Timsah at Ismailia, and the Great Bitter Lake in the central section. The Great Bitter Lake historically functioned as a passing point for traffic moving in opposite directions before the 2015 expansion added a parallel channel that now allows simultaneous two-way transit through much of the canal’s length.

Vessels transiting between Europe and Asia via the Mediterranean rely on the Suez Canal as the only direct connection between the two basins. The next-best alternative is to sail around the southern tip of Africa via the Cape of Good Hope, a route that adds approximately 3,500 to 4,000 nautical miles and 10 to 14 days to a typical Asia-Europe voyage.

This geographic uniqueness gives the canal disproportionate weight in the global maritime system. There is no parallel canal, no land-bridge alternative for most cargo categories, and no comparable artificial waterway elsewhere in the world. Disruptions to transit, therefore, translate immediately into voyage diversion, schedule disruption, and elevated freight costs across the global trading economy.

A Brief History of the Suez Canal

Attempts to connect the Mediterranean and the Red Sea date back to pharaonic Egypt, when canals were dug to link the Nile to the Red Sea under Pharaoh Necho II and later restored under Persian and Roman rule. None of those early canals survived as a permanent waterway.

The modern Suez Canal was built between 1859 and 1869 under French diplomat Ferdinand de Lesseps and the Suez Canal Company. It opened on November 17, 1869, and immediately transformed global trade routes by eliminating the need to round Africa for voyages between Europe and Asia. Control of the canal passed through multiple hands over the next century, with British and French interests dominating until Egyptian President Gamal Abdel Nasser nationalized the canal in 1956.

The canal was substantially upgraded in August 2015 with the opening of the New Suez Canal, an 8.5-billion-dollar expansion project that added a 35-kilometer parallel channel and deepened and widened 37 kilometers of the existing canal. The expansion allowed two-way transit through the central section and significantly increased daily transit capacity.

Approximately 26,000 vessels transited the canal in 2023, the pre-crisis peak, averaging around 70 ships per day. The canal typically carried between 19,000 and 26,000 vessels per year (50 to 70 ships per day) across container shipping, bulk carriers, tankers, and roll-on/roll-off traffic. The Houthi disruption that began in late 2023 has pushed transits well below this range, with traffic remaining 60% below pre-crisis levels through early 2026.

Why the Suez Canal Is One of the World’s Most Important Maritime Chokepoints

The Suez Canal plays a foundational role in global trade because it provides the only direct maritime connection between Europe and Asia. Together with the Bab el-Mandeb Strait at the southern end of the Red Sea, the canal forms a corridor that carries approximately 12% of global maritime trade, including roughly 30% of all global container traffic and 8 to 10% of seaborne oil trade.

The canal is particularly central to specific trade flows. Container shipping between Asian manufacturing hubs and European consumer markets, refined petroleum products moving between Middle Eastern refineries and European buyers, and liquefied natural gas (LNG) flows between Gulf producers and Mediterranean importers all depend on the Suez route.

What makes the Suez Canal especially sensitive is the absence of comparable alternatives. When transit becomes unsafe, restricted, or physically blocked, vessels have only one practical choice, which is the long Cape of Good Hope reroute described above. The result is significantly higher fuel costs, insurance premiums, and freight rates.

The Suez Canal Authority generates multi-billion-dollar annual transit revenue for Egypt, which historically has totaled around 9 to 10 billion dollars per year. Sharp reductions in traffic, such as those experienced from late 2023 onward during the Houthi crisis, translate directly into significant losses for Egyptian state revenue and add fiscal pressure to wider regional dynamics.

Major Global Maritime Chokepoints

Among these routes, the Suez Canal occupies a distinct position because it is an engineered chokepoint rather than a natural strait. It exists only because it was built, and its operations depend on continuous Egyptian state management, dredging, and security. Its physical structure also means that a single grounding, mechanical failure, or attack can block the canal entirely, as the EVER GIVEN incident in March 2021 demonstrated.

Conflicts, Disruptions, and Geopolitical Tensions

Because the Suez Canal is so central to global trade, it has been at the heart of several major geopolitical and operational disruptions over the past century, each of which reshaped global shipping flows in measurable ways.

The Suez Crisis of 1956

In July 1956, Egyptian President Gamal Abdel Nasser nationalized the Suez Canal Company, transferring ownership from British and French shareholders to the Egyptian state. The move triggered a tripartite invasion by Israel, the United Kingdom, and France in October and November 1956, with the stated aim of restoring international control over the canal. Under heavy diplomatic pressure from the United States and the Soviet Union, the invading forces withdrew, and Egyptian sovereignty over the canal was confirmed. The crisis is widely regarded as the moment that signaled the end of British and French imperial reach in the Middle East and consolidated Egypt’s status as the canal’s permanent operator.

The 1967 to 1975 Closure

The canal was closed in June 1967 during the Six-Day War between Egypt and Israel and remained closed for the next eight years. Fifteen merchant ships from various countries were trapped in the canal for the duration, becoming known as the Yellow Fleet because of the desert sand that accumulated on their decks. The closure forced global shipping to reroute around the Cape of Good Hope for nearly a decade, contributing to the development of much larger crude oil tankers, sometimes called supertankers, designed to make the longer route economically viable. The canal reopened in June 1975 after extensive de-mining and dredging operations.

The Ever Given Grounding, March 2021

On March 23, 2021, the 400-meter container ship EVER GIVEN ran aground diagonally across the canal in a southerly section near Suez, blocking the waterway in both directions. The vessel was successfully refloated on March 29 after a six-day salvage operation involving tugs, dredgers, and high tides. The blockage held up more than 400 vessels at peak and disrupted global supply chains for weeks afterward, with industry estimates putting the daily trade impact at approximately 9.6 billion dollars. The incident demonstrated how a single grounding event in the canal could cascade into global supply chain disruption within hours.

The Houthi Red Sea Campaign, 2023 to 2025

From November 2023 onward, the Iran-backed Houthi movement in Yemen conducted what has been described as the most sustained attack on commercial shipping in modern history, targeting vessels in the southern Red Sea, the Gulf of Aden, and the wider region using anti-ship ballistic missiles, anti-ship cruise missiles, one-way attack drones, and uncrewed surface vessels. According to reports, the Houthis attacked or hijacked ships 99 times between November 2023 and September 29, 2025. 

The campaign forced the majority of container shipping lines and a significant share of bulk and tanker operators to reroute around the Cape of Good Hope. Suez Canal transits fell dramatically from January 2024 onward, with quarterly deadweight tonnage capacity through the canal running 51 to 64% below 2023 levels through 2024 and 2025.

The October 2025 Gaza Ceasefire and Suez Recovery

The Gaza ceasefire took effect on October 10, 2025, and the Houthis declared an end to attacks on commercial shipping on November 11, 2025. The Sharm El-Sheikh peace summit in October 2025 was specifically cited by the Suez Canal Authority as paving the way for restoring traffic in the region.

Recovery has been gradual rather than immediate. In the first week of 2026, Suez Canal transits remained approximately 60% below the corresponding week in 2023, according to BIMCO, as carriers continued to assess security thresholds, insurance markets adjusted slowly, and operational schedules reflected the long lead times required to re-rotate fleets back through the Red Sea. The first Maersk vessel to transit the canal since early 2024, the Maersk Sebarok, made its passage on December 19, 2025, and CMA CGM announced the return of its INDAMEX services to Suez routings beginning January 2026. Maersk and Hapag-Lloyd, operating jointly through the Gemini Cooperation alliance, transitioned their ME11 service, connecting India and the Middle East with the Mediterranean, to Suez routing in early February 2026, the alliance’s first Suez transit since its formation in February 2025.

War-risk insurance premiums dropped to roughly 0.2% of hull value by early December 2025, the lowest level since November 2023, down from roughly 0.5% during the active Houthi campaign, though they remained above pre-crisis baselines.

Persistent Risk Factors

Even with the Houthi cessation, vessels transiting the Suez Canal corridor continue to operate in an elevated-risk environment. GPS jamming and spoofing remain reported issues across the wider Red Sea and eastern Mediterranean. Houthi officials have warned that attacks could resume if Gaza hostilities restart. The wider Middle East security picture, including the ongoing Strait of Hormuz situation from February 2026, has kept maritime risk premiums and routing decisions in flux.

How Disruptions in the Suez Canal Affect Global Trade

Because the Suez Canal is the only direct maritime connection between Europe and Asia, disruptions to transit produce immediate and measurable effects on global trade.

When the canal becomes unsafe or physically blocked, vessels reroute around the Cape of Good Hope, adding approximately 3,500 to 4,000 nautical miles and 10 to 14 days to a typical Asia-Europe voyage. This extension drives higher fuel consumption, higher voyage costs, higher insurance premiums, and higher freight rates that ultimately pass through to consumer prices.

The disruption is most visible in container shipping, where just-in-time delivery and tightly managed inventories make schedule reliability central to commercial value. The 2024-2025 Houthi disruption pushed Asia-Europe container freight rates to multi-year highs and forced major carriers to redesign their service networks for the Cape route. Energy markets are also exposed, with European refiners and LNG buyers facing higher landed costs when Gulf-origin cargoes are forced around Africa.

Beyond the direct cost impact, prolonged Suez disruption has structural effects on the global fleet. Longer voyages absorb shipping capacity, tightening the effective supply of vessels available for spot fixtures and pushing charter rates higher across multiple segments.

Monitoring Strategic Chokepoints

Chokepoints like the Suez Canal highlight the importance of continuous monitoring of vessel behavior, traffic patterns, and security signals in high-risk maritime regions.

Governments, navies, shipping companies, and maritime risk teams rely on technologies including satellite imagery, AIS vessel tracking, behavioral analytics, anomaly detection, and multi-source maritime intelligence to understand activity in these corridors.

Platforms such as Windward Maritime AI™ combine behavioral analysis, satellite data, ownership intelligence, and vessel history to monitor traffic in strategic waterways and identify unusual or high-risk vessel behavior, including AIS manipulation, dark activity, and ship-to-ship transfers conducted in unusual locations.

By analyzing vessel movements across multiple data sources, maritime stakeholders can maintain situational awareness through periods of disruption like the Houthi crisis and respond to evolving risk in real time.
