The Suez Canal and the parallel SUMED (Suez Mediterranean) pipeline together constitute one of the most important oil transit corridors in the world. The Suez Canal — the artificial waterway connecting the Mediterranean Sea to the Red Sea, opened in 1869 — handles approximately 7-9% of global oil and refined products trade in normal conditions. The SUMED pipeline, completed in 1977, provides a parallel land-based route that can carry crude that is too large for the canal or that benefits from bypassing the canal for cost or scheduling reasons. Together they handle several million barrels per day of crude and refined products in normal market conditions.
The combined Suez-SUMED system has been disrupted multiple times in recent years, with each disruption producing immediate impact on freight rates, trade flows, and oil pricing. The 2021 Ever Given blockage, the 2023-onwards Houthi attacks on Red Sea shipping that have rerouted much commercial traffic around the Cape of Good Hope, and various smaller incidents have made Suez transit one of the more closely watched single infrastructure variables in global commodity markets.
The Suez Canal
The Suez Canal is an artificial sea-level waterway in Egypt, running approximately 193 kilometers from Port Said on the Mediterranean Sea to Suez on the Red Sea. The canal was built between 1859 and 1869 under the leadership of Ferdinand de Lesseps and was operated by a French-British consortium until its 1956 nationalization by Egypt's Nasser government — an event that triggered the Suez Crisis war.
The canal has been expanded multiple times to accommodate larger vessels and increased traffic. The 2015 New Suez Canal project added approximately 35 kilometers of parallel channel, allowing two-way traffic in a portion of the canal that had previously required convoy management. Current canal depth allows transit of vessels up to approximately Suezmax class (typically 150,000-160,000 deadweight tons) fully laden. Very Large Crude Carriers (VLCCs, typically 200,000-320,000 DWT) require partial loading to transit the canal, which has constrained VLCC use of the route.
The canal generates substantial transit fees for Egypt — typically $7-9 billion per year in normal conditions — making canal revenue one of the country's most important sources of foreign exchange. The Suez Canal Authority (SCA) operates the canal under Egyptian state authority.
Oil Volumes Through Suez
Crude oil and refined products together represent approximately 7-9% of total Suez Canal traffic in normal conditions, with oil-product transit volumes typically running 5-7 million barrels per day. The principal traffic patterns:
- Northbound (Red Sea to Mediterranean). Crude oil flows from Persian Gulf producers (particularly Saudi Arabia, Iraq, Kuwait) and from Asian refining hubs to European and Atlantic Basin markets. Refined products flows from Indian, Middle Eastern, and Asian refining to European markets.
- Southbound (Mediterranean to Red Sea). Russian crude flows that have substantially expanded post-2022 as Russian exports redirected to Asian markets via Suez routing. European refined product flows to Africa, Asia, and other destinations.
The Suez Canal's relative importance has shifted with global trade patterns. Pre-2022, Suez was the principal route for Persian Gulf oil flowing to Europe and for European oil flowing to Asia. Post-2022, the routing patterns have shifted substantially with Russian crude redirection now dominating the Mediterranean-to-Asia routes that were previously dominated by other flows.
The SUMED Pipeline
The Arab Petroleum Pipelines Company (SUMED) operates the SUMED pipeline, a 320-kilometer crude oil pipeline running from the Ain Sukhna terminal on the Gulf of Suez (Red Sea) to Sidi Kerir terminal on the Mediterranean coast near Alexandria. The pipeline provides an alternative route for crude that cannot or chooses not to transit the canal:
VLCC compatibility. VLCCs that cannot transit the canal fully laden can offload at Ain Sukhna, with crude pumped through SUMED for reloading onto Mediterranean tankers at Sidi Kerir.
Partial bypass economics. Even for vessels that could transit the canal, SUMED is sometimes economical given canal transit fees, scheduling considerations, and other factors.
Mediterranean refining destination. Crude destined for Mediterranean refining can be more efficiently delivered via SUMED than by full canal transit to onward Mediterranean shipping.
SUMED capacity is approximately 2.4 million barrels per day, with actual utilization variable based on commercial demand. The pipeline is owned by a consortium including Saudi Aramco, the Kuwait Petroleum Corporation, the Abu Dhabi National Oil Company, Qatar Petroleum, and the Egyptian General Petroleum Corporation — reflecting the regional Arab cooperation that originally established the project.
SUMED operations are physically protected from Red Sea shipping security threats that affect the broader Suez corridor, providing a partial alternative during disruption episodes. However, SUMED still depends on Red Sea loading at Ain Sukhna, which means crude must still transit the Bab el-Mandeb chokepoint to reach the Ain Sukhna terminal.
The 2021 Ever Given Blockage
One of the most prominent recent Suez disruptions was the March 2021 grounding of the Ever Given, a 20,000-TEU container vessel that ran aground in the southern section of the canal and blocked all traffic for six days. The blockage was a major global trade disruption affecting hundreds of vessels and substantial cargo volumes, though the direct oil market impact was more limited than for the canal's broader trade importance:
- Approximately 60 oil tankers were among the vessels delayed by the blockage
- Oil prices rose modestly during the blockage but did not spike substantially given the relatively short duration
- Refined product flows to Europe were more directly affected than crude flows
- Insurance market and freight market impacts were more sustained than the price effects
The incident highlighted the canal's vulnerability to single-vessel incidents and prompted some review of canal traffic management protocols.
The Houthi Crisis and Cape of Good Hope Rerouting
The most consequential recent disruption to Suez oil transit has been the Houthi attacks on Red Sea shipping that began in late 2023. The Yemen-based Houthi movement, in nominal solidarity with Hamas during the Israel-Hamas war that began in October 2023, began attacking commercial vessels transiting the southern Red Sea and Bab el-Mandeb strait. The attacks targeted both oil-product vessels and broader commercial shipping with claimed ties to Israel, the United States, the United Kingdom, or other countries the Houthis identified as adversaries.
The attacks produced widespread commercial rerouting:
- Container shipping — Major container lines (Maersk, MSC, CMA CGM, Hapag-Lloyd, and others) substantially rerouted Asia-Europe traffic around the Cape of Good Hope, adding 10-14 days to typical voyage times and substantially increasing freight rates
- Oil tanker rerouting — A significant share of oil tanker traffic rerouted around the Cape, with the actual share depending on vessel type, flag, ownership, and cargo origin/destination
- Suez Canal revenue collapse — Canal transit revenues declined by approximately 60% during peak disruption periods as traffic fell substantially
- SUMED partial substitution — SUMED utilization increased as some vessels avoided Red Sea transit to Suez Canal in favor of land-route alternatives
U.S. and U.K. military strikes on Houthi positions, combined with multinational naval escort operations, have moderated the attacks at various points but have not fully restored normal Red Sea transit confidence. The disruption has continued in various intensities since late 2023.

Cape of Good Hope Routing Economics
The Cape of Good Hope alternative — sailing around the southern tip of Africa rather than through Suez — adds substantial voyage time and cost:
- Voyage time addition — Typically 10-14 days for an Asia-Europe voyage, with corresponding implications for fleet utilization
- Fuel cost addition — Substantial incremental bunker fuel consumption from the longer voyage
- Freight rate implications — Tanker freight rates have risen substantially during peak Red Sea disruption periods, with Cape routing being one of the principal drivers
- Cargo cycle implications — Slower voyage cycles mean less effective fleet capacity, tightening tanker markets generally
- Refined product implications — European product imports from Indian and Middle Eastern refining face particularly significant Cape routing cost
The Cape routing premium has typically been $3-8 per barrel in normal disruption periods, occasionally higher during acute episodes. For long-duration disruptions, the premium becomes a structural feature of commercial pricing rather than a temporary phenomenon.
Egyptian Strategic Position
Egypt's role as the operator of both Suez Canal and SUMED gives the country substantial strategic positioning in global oil trade. Suez Canal revenues are critical to Egyptian foreign exchange, and the country has substantial incentive to preserve canal operations even during regional instability episodes. Egyptian relations with both Red Sea and Mediterranean states are shaped substantially by canal-related considerations.
The Egyptian government has periodically pursued infrastructure investments to expand canal capacity, improve SUMED operations, and develop additional pipeline projects (including various proposals for parallel pipelines). The longer-term Egyptian strategic objective is to consolidate position as the principal oil transit hub between the Red Sea and Mediterranean.

The Suez Canal and SUMED Pipeline in One Sentence
The Suez Canal and SUMED pipeline together handle approximately 7-9% of global oil trade in normal conditions — a critical Mediterranean-Red Sea transit corridor whose disruption by the 2021 Ever Given grounding and the post-2023 Houthi attacks has produced major rerouting around the Cape of Good Hope and substantial freight rate impact across global tanker markets.
