Two Chokepoints, One Crisis
The global shipping industry has dealt with chokepoint disruptions before. The Suez Canal blockage in 2021 cost an estimated $9.6 billion per day. Houthi attacks in the Red Sea since 2023 forced major rerouting. But what we face in 2026 is categorically different.
For the first time, two of the world's most critical maritime chokepoints are under simultaneous threat — and their combined disruption creates risks that are far greater than the sum of their parts.
The Strait of Hormuz: The Oil Jugular
The Strait of Hormuz is a narrow passage between Iran and Oman, just 21 miles wide at its narrowest point. It connects the Persian Gulf — home to Saudi Arabia, UAE, Qatar, Kuwait, and Iraq's export terminals — to the open ocean.
Key facts:
- Handles approximately 21 million barrels of oil per day
- Carries 95% of Persian Gulf petroleum exports
- Transits roughly $3.4 trillion in annual trade
- Affects commodities: crude oil, LNG, petrochemicals (polyethylene, polypropylene, methanol), aluminum, sulfur, fertilizers
Iran has repeatedly threatened to close the strait, and recent military exercises have demonstrated the capability to do so with mines, fast-attack boats, and anti-ship missiles.
Bab el-Mandeb: The Red Sea Gateway
The Bab el-Mandeb Strait sits between Yemen and Djibouti/Eritrea, connecting the Red Sea to the Gulf of Aden. Any ship using the Suez Canal to transit between Asia and Europe must pass through Bab el-Mandeb.
Key facts:
- Approximately 17,000 vessels transit annually
- Carries roughly 12-15% of all global trade
- Houthi forces have launched 100+ attacks on commercial shipping since late 2023
- Major carriers have suspended Red Sea transit indefinitely
The Houthi threat has proven persistent and adaptive. Despite US and UK military operations, attacks continue, and there is no indication the threat will diminish in 2026.
What Is "Compound Risk"?
Here is what most procurement teams get wrong: they assess Hormuz risk and Bab el-Mandeb risk independently. They run scenarios for one or the other being disrupted. But they rarely model what happens when both are compromised simultaneously.
This is compound risk, and it fundamentally changes the logistics calculus.
When only Bab el-Mandeb is disrupted, vessels can reroute around the Cape of Good Hope — it adds time and cost, but the cargo still moves. Gulf-origin commodities can still exit through Hormuz and head south around Africa.
When only Hormuz is disrupted, non-Gulf suppliers can still route through the Red Sea and Suez Canal to reach Europe and the US East Coast efficiently.
But when both are disrupted? There is essentially no efficient route for Gulf-origin commodities to reach Western markets. The Cape of Good Hope becomes the only option, and it must absorb the rerouted traffic from both chokepoints simultaneously.
The Cascading Effects
The compound disruption creates a cascade of escalating consequences:
Insurance Premiums: +200-400%
War risk insurance premiums for vessels transiting either chokepoint have already spiked dramatically. When both are flagged as high-risk, many insurers simply refuse coverage. The vessels that do transit face premiums that add $500,000-$2 million per voyage to shipping costs.
Shipping Costs: 3x Increase
Container shipping rates on affected routes have tripled compared to pre-crisis levels. The Cape of Good Hope reroute adds 3,000-4,000 nautical miles to a typical Gulf-to-Europe voyage, consuming more fuel and tying up vessel capacity.
Lead Times: 2x Longer
A standard Gulf-to-Rotterdam voyage takes approximately 18-20 days via Suez. The Cape reroute extends this to 30-35 days. For just-in-time procurement operations, this doubling of lead time can be catastrophic.
Port Congestion
As more vessels take the longer Cape route, they arrive at destination ports in irregular clusters rather than steady flows. This creates port congestion, further adding 2-5 days of delay on top of the rerouting penalty.
Price Transmission
All of these cost increases are passed through the supply chain. The end result is the commodity price spikes we are seeing: polyethylene up 15-20%, aluminum up 8-12%, sulfur up 20-25%, and fertilizers up 10-15%.
Real Data From the Current Crisis
The numbers are not projections — they are observations from the ongoing disruption:
- Polyethylene spot prices are up 18% since dual-threat escalation in January 2026
- Container rates on Asia-Europe routes have increased from ~$2,000/TEU to ~$6,500/TEU
- Average transit times for Gulf-origin cargo have increased from 22 days to 38 days
- Marine insurance war risk premiums now represent 1.5-3% of cargo value, up from 0.1%
Why Single-Chokepoint Risk Assessment Is Dangerous
Most enterprise risk frameworks model disruptions as isolated events. A Hormuz closure is one scenario. A Red Sea disruption is another. The probability of each is assessed independently, and the combined probability is assumed to be multiplicatively small.
This assumption is fundamentally flawed because the two disruptions are correlated. Regional instability that threatens Hormuz is often linked to the same geopolitical dynamics that empower Houthi operations at Bab el-Mandeb. These are not independent risks — they are connected, and they are currently co-occurring.
Procurement teams that only model single-chokepoint scenarios are underestimating their true exposure by 40-60%, according to our analysis of client portfolios.
What You Should Do
The first step is understanding your actual dual-chokepoint exposure — not just which suppliers are in the Gulf, but which logistics routes transit either or both chokepoints.
SourceShift is the only tool that scores dual-chokepoint exposure across your entire commodity portfolio. Our assessment analyzes your supplier base against both Hormuz and Bab el-Mandeb risk simultaneously, using real shipping route data and 70M+ customs records.
