Group 5 Flash Research: A blocked node costs the same whether or not anyone meant to block it. When the Ever Given ran aground in the Suez Canal in March 2021, the world discovered just how fragile a single chokepoint can be — no malice required.
Without the Suez Canal, Asia-Europe trade must go around Africa — adding 7,000 km and 7-10 days to every voyage. One narrow waterway carries 12% of global trade and 30% of all container traffic.
~50 ships transit daily · ~12,000 km from Shanghai to Rotterdam · Transit time: ~14 hours · Carries 12% of global trade and 30% of container traffic · The canal saves approximately 7,000 km and 7-10 days compared to the Cape of Good Hope route. Each ship pays an average of $300,000-$700,000 in tolls — still far cheaper than the fuel cost of going around Africa.

The Ever Given case teaches us the critical difference between:
Yet the economic damage was identical. The global supply chain does not distinguish between a blockade and an accident. The vulnerability is the same — only the intent differs.
The PPT's framework: "Credible threat, proportionate response, burden on the wielder, exit ramp." Let's see what happens when we apply it to an accidental chokepoint.
What would a deliberate closure, held for as long as someone chose, be worth as leverage?
The Suez Canal is a textbook single node. No locks, no bypass within the canal itself, and the alternative (Cape of Good Hope) adds 7,000 km and 7-10 days. There are zero near-term substitutes for this geography.
The Cape route exists but costs vastly more in fuel, time, and emissions. A full reroute would take years to normalize. The 1967-1975 closure (8 years) proved the world can adapt, but at enormous cost. In the near term, there is no real substitute.
Egypt would lose ~$6 billion/year in canal revenue — a significant hit for its economy. But global trade disruption would cost far more ($9.6B/day). The asymmetry exists, but the holder bleeds too. The question is whether the holder considers the trade-off worth it.
Egypt has never deliberately closed the canal outside of wartime (1956, 1967). A state that controls the canal and is willing to absorb the revenue loss + international condemnation could theoretically hold the world hostage. The 6-day accident proved the mechanism works perfectly — it just lacked intent.
| Event | Duration | Cause | Deliberate? | Global Impact |
|---|---|---|---|---|
| Suez Crisis | 5 months (1956-1957) | War: Egypt nationalized canal; UK, France, Israel invaded | Yes — weaponized | Oil shortages in Europe; US pressured allies to withdraw |
| Six-Day War Closure | 8 years (1967-1975) | War: Egypt blocked canal after Six-Day War | Yes — strategic | Global shipping rerouted around Africa; trade distances increased ~50% for Asia-Europe routes |
| Ever Given Grounding | 6 days (March 2021) | Accident: wind, sandstorm, possible human error | No — accidental | $57.6B cargo delayed; 422 ships backlogged; $9.6B/day in held goods |
| Hypothetical: Deliberate Closure | As long as the holder chooses | Political/military coercion | Yes — weaponized | $9.6B/day × indefinite = catastrophic. Insurance markets would collapse. Global energy prices would spike. |
A chokepoint is powerful, and using it is how you teach the other side to escape it.
Q1: Try to point the four-part test at this case and see what happens. Who is the wielder? What is the threat? Where does the burden sit?
The four-part test breaks when applied to the Ever Given because there is no wielder and no threat. The test was designed for political chokepoints where a state deliberately turns the valve. Here, the valve was turned by physics — wind, sand, and a ship. The burden was distributed globally: shipping companies (Maersk lost $89M), Egypt ($95M in tolls), global manufacturers (production delays), and consumers (price increases). No single actor was responsible, and no single actor could be held accountable.
Q2: What does the case teach about the difference between a chokepoint that exists and a chokepoint that is used?
A chokepoint that exists is a structural vulnerability — geography, infrastructure, or market concentration that creates a single point of failure. The Suez Canal exists as a chokepoint every day, and the global economy treats it as reliable infrastructure.
A chokepoint that is used is a weapon — someone actively exploits the vulnerability for political or economic leverage. The 1956 and 1967 closures were used chokepoints.
The critical insight: the damage does not distinguish between the two. A 6-day accident caused $57.6 billion in disruption. A 6-day deliberate blockade would cause exactly the same. The existence of the chokepoint is the risk — use is just a matter of intent.
Q3: Scale it up — what would a deliberate closure, held for as long as someone chose, be worth as leverage?
At $9.6 billion per day, a deliberate Suez blockade would be one of the most powerful economic weapons in existence. A one-month closure would delay ~$288 billion in trade. A three-month closure would exceed $860 billion — comparable to the GDP of a mid-sized country.
The leverage comes not just from the direct economic damage, but from supply chain cascades: factory shutdowns in Europe for lack of Asian components, energy price spikes, insurance market collapse, and inflation in consumer goods. The holder could demand almost anything — territory, sanctions relief, policy changes — and the cost of refusal would be measured in billions per day.
However, as the PPT teaches: "Every use of the valve teaches the target to build around it." A prolonged blockade would trigger exactly the 1973 oil embargo pattern — strategic reserves, alternative routes (Arctic, rail), accelerated canal expansion elsewhere, and a permanent reduction in dependence on the Suez route. The weapon is most powerful when used sparingly.
