- Regional weather/sea-state disruption (winter storm season Jun–Aug)
- Insurance claims filed for delay-related cargo losses
● BASE CASE De-escalation: Normalization & Hormuz Return(14%)
Timeline: 8–12 weeks to partial reversion
Hormuz traffic recovers to 50–70% of baseline; 30–40% of diverted Cape traffic gradually reverts to Suez/Hormuz. Voyage times normalize; freight rates compress toward +8–12% above pre-crisis baseline within 8–10 weeks.
Key Indicators
- Hormuz traffic recovery (AIS confirmation, >25% of baseline)
Timeline: 4-8 weeks to establish new flow patterns; sustained 12+ weeks if Hormuz remains constrained
Cape routing becomes permanent for 25-35% of previously Hormuz-dependent crude and 15-20% of container traffic. Bunker barge availability tightens; congestion at Cape approaches creates 3-5 day delays. Spot rates on Cape-routed corridors stabilize at premium +$1000-1500/TEU.
Key Indicators
- Monthly Cape transit count (baseline: track increase from historical 8-12% of global traffic to 25-35%)
- Crude tanker queue at Cape approaches (monitoring: Durban, Walvis Bay port congestion)
- Bunker barge availability index (price and slot availability at Cape bunkering hubs)
- Asia-Europe spot rates via Cape (tracking premium vs. Suez baseline; target: +$1000-1500/TEU = sustained diversion)
- Piracy incident frequency at Cape (monitoring: any uptick in Gulf of Guinea/Cape incidents)
● BASE CASE Cape Congestion Crisis(22%)
Timeline: Escalates if Hormuz closure >8 weeks; peak congestion weeks 10-14 of prolonged Hormuz closure
If Hormuz closure extends beyond 8 weeks, Cape becomes bottleneck with 40+ vessel queues forming; bunker supply exhaustion at Durban/Cape Town; towage capacity fully committed. Port demurrage costs spike +$200K-400K/vessel; transit times extend to 10-14 days at Cape approaches.
Timeline: De-escalation signal within 2-3 weeks of Hormuz reopening; full normalization 4-6 weeks
If Hormuz reopens or alternative northern routes (Arctic, Northern Europe gateway) gain viability, Cape diversions normalize to 12-15% baseline. Spot rates on Cape routes fall to +$400-600/TEU premium. Bunker availability improves; transit delays at Cape clear within 1-2 weeks.
- Bunker availability at Cape normalizes; prices fall within +$30-50/mt of global baseline
- Container line guidance stability on Cape-routed lanes (no further premium escalation)
● BASE CASE Base Case: Cape Becomes Default Route(62%)
Timeline: Immediate–Q2 2026 (structural shift)
Cape of Good Hope absorbs 40–50% of diverted Hormuz crude and 25–30% of diverted Asia-Europe container traffic, becoming the de facto trunk route. Waiting times stabilize at 3–5 days at Cape Verde approach; port congestion manageable but chronic at Cape ports (Durban, Port Elizabeth).
- Durban/Port Elizabeth congestion: 2–3 week turnarounds for smaller vessels
- Bunker consumption at Cape: +35–40% YoY
- ULCV/Neo-Panamax deployment to Cape routes increases 50%+
● BASE CASE Escalation: Cape Bottleneck & Congestion Crisis(24%)
Timeline: Days 0–14 (routing shift); Days 14–60 (port congestion); Days 60–120 (adjustment or infrastructure investment)
Simultaneous Hormuz and Suez closures force 60–70% of trade to Cape; South African port infrastructure reaches capacity limits with 4–8 week vessel delays. Durban port strike or adverse weather (cyclone season) compounds bottleneck; spot rates for Cape transits spike 60–80%.
Key Indicators
- Cape transits spike to 300+ vessels/month
- Waiting times: 5–8 weeks at Cape Verde approach; 3–4 weeks at Durban anchorage
- Durban turnaround times: 4–6 weeks (vs. normal 3–4 days)
- Spot freight rates for Cape routes: +60–80% above base
- Vessel size constraints emerge: <6,000 TEU ships avoid Cape due to delays
- South African port authority implements traffic restrictions
● BASE CASE De-escalation: Hormuz & Suez Reopen, Cape Returns to Contingency(14%)
Timeline: Days 0–7 (de-escalation signal); Days 7–21 (traders pivot); Days 21–60 (market rebalance)
Hormuz and Suez normalize (partial reopening or deal-driven de-escalation); traders rapidly shift away from Cape back to historical chokepoints. Cape transits drop to 100–120 vessels/month; port congestion clears within 2–3 weeks; freight rates on Cape routes normalize to baseline +3–5%.
Key Indicators
- Cape transits drop to 100–130 vessels/month
- Waiting times normalize to <1 day at Cape Verde
- Durban turnarounds return to 3–4 day baseline
- Spot freight rates on Cape routes drop 25–35%
- ULCV/Neo-Panamax deployment to Cape routes normalizes to 30–40/month
- Bunker spreads between Singapore and Cape normalize
