How vulnerable is global maritime commerce…maybe more than we think.

On March 23rd when the 20,000 TEU Ever Given ran aground and wedged itself across the Suez Canal, all traffic through the critical waterway came to a standstill. It was aground in the Canal for a mere six days but the cascading impact on the global supply chain is still being felt weeks later.

It’s understandable. The Suez Canal averages over 90 vessel transits a day nominally linking the Mediterranean Sea to the Red Sea. But in reality, the Suez ties Asia to Europe. The 120-mile long waterway saves around 6,100 miles of transit using London, UK – Mumbai, India as two base points. The difference is roughly 26 days to 44 in sea time.

More to the point, when it comes to moving goods to and from Asia to Europe, although it comes at a premium, the Suez Canal is really the only way to go. The alternative is going around the Cape of Good Hope, which is not only longer but would omit the port opportunities of the Mediterranean – in short, the long haul is bad business. At various times in the past, tankers have avoided using the 120 mile waterway to save cash on canal fees, but the rotations of boxships obviates this rationale. Containerships are tied to their loops and the Suez is critical to that end.

But the Suez isn’t the only maritime choke point, in fact there are eight primary maritime choke points and dozens of secondary ones (see map on next page). The primo eight (in AJOT’s estimation) are the Panama Canal, the Strait of Gibraltar, Cape of Good Hope, Bosporus Strait, Suez Canal, Bab-el-Mandeb Strait, Strait of Hormuz and Straits of Malacca.

The two canals, Panama and Suez have both become essential to the flow of containerized freight. In the case of the Panama Canal, the expansion has made it crucial as the Trans-Pacific direct call connector to the U.S Gulf and East Coast ports.

In combination with the Suez, this enables carriers to run interlinking global loops that link Asia to North America from both East and West. Which brings us to the point of vulnerabilities. If the Panama Canal had also been compromised at the same time as the Suez, what would the damage be to the global supply chain?

Of course, the majority of the choke points are “straits” which are less vulnerable to calamities like malfunctioning locks or vessel groundings but the risk factor is still significant in geo-political terms. For example, the Strait of Bab-el-Mandeb (Gate of Tears in Arabic), is located between the Arabian Peninsula and northeast Africa. The narrows are considered to be the world’s fourth busiest waterway and part of the sea route from the Indian Ocean to the Red Sea and the Suez Canal. Both sides of the waterway are volatile with the war in Yemen a global concern, unrest in Djibouti and…
