ONE ROUTE CLOSES. THE WORLD ADAPTS. TWO ROUTES CLOSE. THE WORLD BREAKS.

There are two ways to move goods between Asia and Europe by sea. The northern route goes through the Suez Canal, passing the Red Sea and the Bab el-Mandeb strait. The southern approach to the Persian Gulf passes through the Strait of Hormuz. Between them, these two chokepoints handle the majority of East-West maritime trade.

As of March 9, 2026, both are effectively closed.

This has never happened before. Not during the Suez Crisis. Not during the Iran-Iraq War. Not during the 2024 Houthi campaign. There is no precedent in modern maritime history for the simultaneous closure of both major East-West shipping routes.


CHOKEPOINT ONE: STRAIT OF HORMUZ

The IRGC declared the Strait of Hormuz closed on March 2. By March 5, the declaration was narrowed in language to target “US, Israeli, and Western allied” vessels - but in practice, the distinction is irrelevant. Most P&I clubs (the mutual insurers that cover commercial shipping) cancelled war risk extensions with 72-hour notice. Without insurance, ships cannot sail.

The numbers as of March 9:

Metric Normal Current
Daily transits 60+ ~3
Ships anchored outside strait ~10-15 150+
Tanker traffic Baseline Down ~90%
War risk insurance 0.05% of hull value Over 1.0% of hull value
Single-voyage premium ($100M tanker) ~$200,000 ~$1,000,000

Major carriers - Maersk, CMA CGM, Hapag-Lloyd - have suspended all Hormuz transits. QatarEnergy declared force majeure on LNG shipments. The strait that carries 20% of the world’s seaborne oil, 20% of global LNG exports, 30% of the world’s helium, and 12% of global aluminum production is functionally offline.

CHOKEPOINT TWO: RED SEA / BAB EL-MANDEB

On February 28, Houthi leader Abdul Malik al-Houthi announced the resumption of attacks on commercial shipping in solidarity with Iran. By March 5, Maersk confirmed rerouting all vessels via the Cape of Good Hope. CMA CGM and Hapag-Lloyd followed within hours.

This is not new - the Houthis disrupted Red Sea shipping throughout 2024, forcing major rerouting. What is new is the timing. The 2024 Houthi campaign gave shippers an alternative: transit via Hormuz instead of Suez. The Hormuz closure gave shippers a different alternative: transit via Suez instead of Hormuz.

Now neither alternative exists.

The Red Sea carries approximately 12-15% of global trade. Seventeen submarine cables run through it. The Suez Canal alone handles $1 trillion in annual trade.

THE HISTORICAL CONTEXT

To understand how unprecedented this is:

Event Year Routes Affected Duration
Suez Crisis 1956 Suez Canal only 6 months
Six-Day War / Suez Closure 1967-1975 Suez Canal only 8 years
Tanker War (Iran-Iraq) 1984-1988 Hormuz partially 4 years (but traffic continued)
Houthi Campaign 2024 Red Sea / Bab el-Mandeb Ongoing (but Hormuz open)
Current Crisis 2026 Both simultaneously Ongoing

The Suez closure of 1967-1975 was one route. Ships rerouted via Hormuz and Cape of Good Hope. The 2024 Houthi campaign was one route. Ships rerouted via Cape of Good Hope while Hormuz remained open. The Iran-Iraq Tanker War partially disrupted Hormuz, but ships continued transiting with escort.

Today, both routes are closed. The only remaining option is the Cape of Good Hope.


THE CAPE OF GOOD HOPE: LAST ROUTE STANDING

Every container ship, tanker, and bulk carrier that would normally transit Hormuz or Suez is now competing for capacity on a single route that adds approximately two weeks to voyage time.

The cost impact:

Cost Factor Before Crisis Current Multiplier
Asia-Europe container rate ~$2,700-$3,600/TEU Rising toward $10,000+/TEU ~3x and climbing
War risk surcharge Minimal $1,500-$4,000/container New cost
Voyage time (Asia-Europe) ~30 days (Suez) ~44 days (Cape) +47%
Fuel consumption per voyage Baseline +30-40% (longer route) 1.3-1.4x
Total shipping cost Baseline ~4.2x baseline See model

The 4.2x shipping cost multiplier is derived from the Supply Chain Cascade model using the “Double Chokepoint” preset. This accounts for the compounding effect of longer voyages (reducing effective fleet capacity), war risk premiums, fuel surcharges, and port congestion at Cape route terminals.

Maersk reported $153 million in losses from Cape diversions in Q4 2025 alone - and that was before Hormuz closed. The current situation is qualitatively different: the Cape route is no longer a temporary diversion. It is the only route.

CHINA’S NAVAL DEPLOYMENT - AND WHY IT DOESN’T MATTER YET

On March 8, China deployed naval assets to the Hormuz area. The immediate reading was hopeful: perhaps China would escort commercial vessels through.

CSIS analysis was blunt: “No one, not even Beijing, is getting through.”

The IRGC has deployed anti-ship missile batteries, naval mines, and fast attack craft throughout the strait. The US Navy is present but not escorting commercial traffic - it is focused on force protection and strike operations against Iran. China’s deployment appears to be a positioning move, not a convoy operation.

Even if China attempted to escort vessels, the insurance problem remains. P&I clubs have cancelled coverage. No major carrier will transit an active war zone without insurance, regardless of which navy offers escort. The financial architecture of commercial shipping is as much a barrier as the military one.

THE DOWNSTREAM CASCADE

Shipping cost is not an isolated variable. It is a multiplier that flows through every supply chain simultaneously.

The transmission mechanism:

Shipping cost -> Import prices -> Producer prices -> Consumer prices -> Inflation -> Interest rates -> Political stability

Every product that crosses an ocean becomes more expensive. Not just the goods that normally transit Hormuz or Suez - all goods, because the Cape route is now congested with diverted traffic, pushing up rates on routes that were previously unaffected.

The previous assessment documented 10 specific supply chains breaking through Hormuz. The double chokepoint does not simply add the Red Sea disruption on top. It eliminates the rerouting option that was absorbing part of the Hormuz shock. The effect is multiplicative, not additive.

Use the Supply Chain Cascade model with the “Double Chokepoint” preset to explore the downstream effects across all sectors.


PREDICTION

ID Prediction Deadline Confidence
pred_2026_069 Container shipping rates Asia-Europe will exceed $10,000/TEU 2026-05-31 50%

Falsified if: Both routes reopen before May 31, OR rates remain below $10,000/TEU despite both routes staying closed (indicating demand destruction or alternative routing absorbs the shock).

Confidence rationale: 50% reflects genuine uncertainty. The rate trajectory is upward and accelerating, but demand destruction (buyers simply not ordering goods they cannot afford to ship) may cap rates before they reach the threshold. The 2024 Houthi crisis pushed rates above $8,000/TEU with only one route disrupted. Two routes closed should push higher, but the relationship is not linear.


FALSIFIABILITY

This assessment would be weakened if:

  1. One or both routes reopen within 2 weeks - buffer stocks and existing voyages in transit would cover the gap
  2. War risk insurers resume coverage for Hormuz transits under naval escort - restoring commercial traffic despite military risk
  3. Cape route capacity proves sufficient - no significant congestion, rates stabilize below 3x baseline
  4. Demand destruction is rapid enough to prevent rate spikes - importers cancel orders rather than pay premium rates
  5. China successfully escorts commercial vessels through Hormuz, establishing a parallel transit corridor

RED TEAM

The strongest argument against this assessment: the market is already pricing it in. Carriers have been Cape-routing since the 2024 Houthi campaign. Fleet repositioning has already occurred. The “shock” of two routes closing is less than it appears because one route (Red Sea) was already largely abandoned by major carriers. The additional closure of Hormuz adds cost but the shipping industry has demonstrated remarkable adaptability.

This is partially valid for container shipping, where Cape routing became standard practice in 2024-2025. It is much less valid for tanker traffic (which continued through Hormuz until March 2), for LNG carriers (which transited Hormuz for Qatar exports), and for bulk carriers (aluminum, fertilizer). These segments had not pre-adapted to alternative routing because they had no reason to. The tanker and LNG shock is genuine, even if container shipping is partially pre-adapted.

The deeper problem with the “markets adapt” argument is capacity. The Cape route adds two weeks per voyage. This means every ship on the route makes fewer round trips per year. Effective global fleet capacity drops even if no ships are damaged. You cannot adapt your way out of a physics constraint.


por. Zbigniew Pattern recognition, not prophecy. 2026-03-09


There are two ways to ship goods between Asia and Europe. For the first time in modern history, both are closed. The last time a single route closed for an extended period - the Suez Canal from 1967 to 1975 - it reshaped global trade patterns for a generation. We are now in uncharted territory.

Verify everything. Trust patterns, not prophecies.
