How much of Italy’s trade passes through the Strait of Gibraltar?

Estimated value of its trade with each partner that crosses the chokepoint; the percentage is the share of all its trade through the chokepoint, not of the pair’s trade.

1. Italy–Germany$117.3 billion · 24.3%
2. Italy–United States$48.6 billion · 10.1%
3. Italy–China$36.5 billion · 7.5%
4. Italy–Netherlands$33 billion · 6.8%

Methodology

We estimate the value crossing each chokepoint from BACI trade that travels by sea according to our mode heuristic, split between each country’s ports by where its GDP is generated and which coast is closest, and routed over our own sea network. It is an estimate, not a count of ships. It covers 99.9% of seaborne trade. The approach follows Verschuur, Lumma and Hall (Nature Communications, 2025). Data up to 2024.
