Track Trade Routes, Chokepoints, and Freight Costs
Track 13 maritime chokepoints, freight indices (BDI, SCFI), trade policy, and critical mineral risks in real time. Free supply chain intelligence dashboard.
Key Takeaways: In the March 15, 2026 snapshot, Strait of Hormuz traffic was down 94.4%. World Monitor monitors 13 waterways, nine freight indices, WTO trade policy, and critical-mineral concentration in one dashboard.
The Strait of Hormuz carries about 20% of global petroleum liquids consumption. In the March 15, 2026 snapshot, World Monitor’s chokepoint tracker showed traffic down 94.4% week-over-week, with tanker transits falling from 60+ daily to single digits and a 99% disruption score.
This was not a hypothetical scenario for a risk assessment deck. The dashboard continues to track live conditions, while the figures below remain an explicitly dated case study.

The Hormuz Crisis in Real Time
The Iran-Israel conflict has turned the Persian Gulf into an active confrontation zone. Iranian naval blockade risks, mines reported in shipping lanes, and 1,300+ security incidents in the past seven days have effectively shut down the world’s most critical energy chokepoint.
World Monitor’s Supply Chain panel shows this in one view:
- 85/100 disruption score with red status
- 94.4% week-over-week traffic decline
- 99% disruption rate across the corridor
- Transit history chart showing the cliff-edge collapse in late February
- AI-generated shipping advisory: reroute via Suez Canal (adds 8-10 days, $150,000-$220,000 per transit), avoid Dubai anchorage, suspend Iran/Iraq crude exports until confrontations cease
The chart tells the story: tanker and cargo traffic that had been steady at 40-70 vessels daily suddenly dropped to near zero. This is not a gradual decline. It is a sudden shutdown of one of the world’s most important trade arteries.
Thirteen Maritime Chokepoints Monitored in Real Time
The Hormuz crisis was the most severe in this snapshot, but it was not the only corridor under pressure. World Monitor tracks 13 critical maritime chokepoints, each scored by disruption level, vessel traffic, and conflict intensity:
The following table highlights eight of the 13 monitored corridors as of mid-March 2026:
| Corridor | Status | Key Risk |
|---|---|---|
| Strait of Hormuz | Critical | Iran-Israel war, naval blockade, mines |
| Kerch Strait | Red | Russia controls Kerch Bridge, Azov grain exports restricted |
| Bab el-Mandeb | Yellow | Houthi attacks on commercial shipping |
| Suez Canal | Yellow | Red Sea conflict spillover, Iran-Israel war adjacency |
| Bosporus Strait | Elevated | Black Sea grain corridor tensions |
| Taiwan Strait | Yellow | PLA military exercises, semiconductor supply risk |
| Cape of Good Hope | Green | Rerouting destination for Hormuz/Suez diversions |
| Dover Strait | Green | Europe’s busiest shipping lane, currently stable |
Each corridor shows live vessel counts, week-over-week traffic changes, disruption percentages, and risk levels. When you click a corridor, you get the full AI-generated situation assessment with specific shipping recommendations.
What Makes This Different From Port Trackers
Traditional maritime tracking tools show you where ships are. World Monitor shows you why they are not where they should be.
The corridor disruption table cross-references AIS vessel data with conflict events, navigational warnings, and military activity. When vessel counts drop in the Strait of Hormuz, the system does not just show a number going down. It tells you there are 1,323 security incidents in the past week, Iranian naval confrontations in the shipping lanes, and mines reported in the Persian Gulf.
The AI advisory goes further: it recommends specific alternative routes, estimates the cost increase per transit, identifies which cargo types should use air freight instead, and warns against specific anchorage points.
Real-Time Freight Cost Tracking
When chokepoints close, freight costs spike. World Monitor tracks nine freight indices that quantify the cost impact of disruptions:
Container Rates:
- SCFI (Shanghai Containerized Freight Index): composite container shipping costs from Shanghai, the world’s busiest port. Currently at 1,710, up 14.9% as rerouting demand increases
- CCFI (China Containerized Freight Index): broader Chinese container export costs. At 1,072, up 1.7%
Bulk Shipping:
- BDI (Baltic Dry Index): the benchmark for dry bulk shipping costs (iron ore, coal, grain). At 1,972, up 2.4%
- BCI (Baltic Capesize Index): largest vessels, long-haul routes. At 2,721, up 5.7%, reflecting longer Cape of Good Hope diversions
- BPI (Baltic Panamax Index): mid-size vessels, grain and coal. At 1,835
- BSI (Baltic Supramax Index): regional trade vessels. At 1,290
- BHSI (Baltic Handysize Index): smaller vessels, coastal trade. At 807
Economic Indicators:
- Deep Sea Freight Producer Price Index (BLS): long-term freight cost trends with 24-month history
- Freight Transportation Services Index (BTS): overall freight sector activity
When you see the Hormuz disruption score at 99% and the Capesize Index up 5.7% in the same dashboard, the connection is immediate: ships that would have taken the short route through Hormuz are now going around Africa, and the cost of booking those larger vessels is climbing. For more on how these costs ripple into commodity markets, see our commodity monitoring guide.
Trade Policy Intelligence
Supply chain disruptions do not happen in isolation. They intersect with trade policy: tariffs, restrictions, and barriers that shape where goods can flow even when shipping lanes are open.
World Monitor’s Trade Policy panel tracks:
- Trade Restrictions: WTO-reported measures by country, showing which economies are tightening import/export controls
- Tariff Trends: applied tariff rates between major trading partners over time
- Trade Flows: bilateral trade volumes between economies (e.g., US-China, US-EU), tracking shifts in trade patterns
- Trade Barriers: SPS (Sanitary and Phytosanitary) and TBT (Technical Barriers to Trade) measures that create non-tariff obstacles
- US Customs Revenue: Treasury collection data that reflects real trade volumes hitting US ports
When the Strait of Hormuz closes, the trade policy data shows the second-order effects: which countries depend on Gulf oil imports, which alternative suppliers face their own trade restrictions, and whether tariff structures make rerouting economically viable.
Critical Minerals: Concentration Risk
Some supply chains cannot be rerouted because the supply itself is concentrated in a handful of countries. The Critical Minerals tab tracks this concentration risk using the HHI (Herfindahl-Hirschman Index), where anything above 2,500 indicates high concentration:
| Mineral | Top Producer | Share | HHI Score | Risk |
|---|---|---|---|---|
| Gallium | China | 96% | 9,280 | Critical |
| Cobalt | DRC | 80% | 6,633 | Critical |
| Germanium | China | 77% | 6,085 | Critical |
| Rare Earths | China | 71% | 5,327 | Critical |
| Lithium | Australia | 50% | 3,529 | High |
Gallium at 9,280 means the global supply is almost entirely dependent on a single country. When China announced gallium and germanium export controls in 2023, the semiconductor industry had no short-term alternative. World Monitor makes this concentration visible, so supply chain teams can assess exposure before restrictions are announced.
How It All Connects
Consider the current Hormuz crisis through all four dimensions:
- Chokepoints: Hormuz at 99% disruption, vessels rerouting to Suez and Cape of Good Hope
- Freight Costs: Capesize Index up 5.7% (longer routes need bigger ships), SCFI up 14.9% (container demand shifting)
- Trade Policy: Gulf oil exports affected by the conflict, alternative suppliers face their own trade barriers
- Critical Minerals: Qatar LNG exports transit Hormuz. Disruption affects downstream petrochemical inputs for battery manufacturing
No single data source shows this full picture. World Monitor puts chokepoint status, freight indices, trade policy, and mineral supply risk in one panel, updated in real time. Combined with AI-powered forecasting, you can see not just what is happening, but where the situation is heading. And if you want these signals in your own systems rather than a dashboard, the API exposes the same data: here is how to build a supply-chain early-warning system with route scoring and disruption webhooks.
The Data Sources
Transparency matters. Here is where the data comes from:
- Vessel transit data: AIS (Automatic Identification System) feeds, cross-referenced with historical baselines
- Conflict events: ACLED (Armed Conflict Location & Event Data Project), 7-day rolling windows
- Shipping advisories: AI-generated from combined conflict, navigational, and AIS disruption signals

Frequently Asked Questions
What is the Baltic Dry Index (BDI)?
The BDI measures the cost of shipping dry bulk commodities (iron ore, coal, grain) on major ocean routes. It is widely used as a leading indicator of global trade activity because it reflects real demand for shipping capacity, not speculation.
How does the Strait of Hormuz affect oil prices?
About 20% of global petroleum liquids consumption and a major share of LNG trade pass through Hormuz. When traffic drops or the strait is threatened, energy markets price in supply-disruption risk. The 94.4% decline cited in this article is a dated March 15, 2026 snapshot, not a current reading.
What are the world’s most critical shipping chokepoints?
World Monitor monitors 13 waterways: Hormuz, Malacca, Suez/SUMED, Bab el-Mandeb, Panama, Taiwan, Cape of Good Hope, Gibraltar, Bosporus, Korea, Dover, Kerch, and Lombok. Seven currently have EIA-backed oil or gas flow baselines; all 13 can carry traffic, warning, threat, and disruption context. See the maritime chokepoint methodology for the canonical registry and coverage limits.
