How much of Finland’s trade passes through the Kiel Canal?

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. Finland–Germany$14.6 billion · 91.2%
2. Finland–Czechia$1.4 billion · 8.8%

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

1. Cars$2 billion · 12.3%
2. Stainless steel sheet$871 million · 5.5%
3. Coated paper$682 million · 4.3%
4. Cargo and cruise ships$593 million · 3.7%
5. Auto parts$579 million · 3.6%
6. Batteries$555 million · 3.5%
7. Refined copper$473 million · 3%
8. Ferrous scrap$461 million · 2.9%
9. Chemical wood pulp$255 million · 1.6%
10. Other industrial machines$213 million · 1.3%

• Germany–Finland: +230 nautical miles, ≈ 0.5 days more at 14 knots, via the Øresund

Estimated sailing detour, without costs, waiting or port capacity.

Helsinki (100%)

Each port with the weight it receives from the country’s trade, based on where its GDP is generated and which coast is closest.

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.

The Kiel figure is the most sensitive to how trade is split between ports: it depends on how much of Germany’s trade is assigned to its Baltic ports, such as Rostock.
