How much of Bulgaria’s trade passes through the Cape of Good Hope?

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. Bulgaria–China$4.4 billion · 49%
2. Bulgaria–Iraq$821 million · 9.1%
3. Bulgaria–Indonesia$570 million · 6.3%
4. Bulgaria–South Korea$356 million · 3.9%
5. Bulgaria–India$332 million · 3.7%
6. Bulgaria–Thailand$286 million · 3.2%
7. Bulgaria–Vietnam$276 million · 3%
8. Bulgaria–Singapore$258 million · 2.9%
9. Bulgaria–Japan$241 million · 2.7%
10. Bulgaria–Bangladesh$184 million · 2%

The products with the highest estimated value in 2024, with their share of the total through the chokepoint.

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.
