Black Sea blockade slashes Ukraine GDP by 1.9 points as metal exports collapse 81%

Russia's ongoing blockade of Black Sea ports is eroding Ukraine's trade income, with the central bank calculating a direct financial loss for the second half of the year. The National Bank of Ukraine (NBU) released these figures in its October inflation report, detailing how the disruption of maritime routes is reshaping the country's export economy.

The NBU estimates that Ukraine will lose $4.6 billion in agricultural export revenues between July and December 2026. This loss stems from the severe drop in grain and oilseed shipments, which fell to a low of 1.8 million tonnes in August. While alternative overland routes helped increase volumes to 2.7 million tonnes in September, the capacity remains constrained compared to pre-blockade levels.

Metallurgical exports face a steeper decline. Ferrous metal exports dropped 55% year-on-year in the third quarter. The central bank expects this decline to widen to 81% year-on-year in the fourth quarter as major plants halt operations. This shutdown will cost an additional $600 million in direct export revenue from ore and approximately $1 billion from finished metals.

The combined impact on the trade balance is projected to reach $6.6 billion in the second half of 2026. This figure includes $400 million in increased imports of metal products needed to cover domestic shortages caused by the plant closures. The NBU notes that the blockade is already affecting the macroeconomic outlook, reducing real GDP growth in 2026 by 1.9 percentage points.

Outlook for 2027 remains challenging under the NBU's baseline scenario. The bank assumes seaports will remain blocked through the first half of next year. Agricultural exports are expected to resume in the second half of 2027, but prolonged storage will result in quality losses. The grain and oilseed harvest for 2027 is forecast to be 2.7 million tonnes lower than normal, costing an estimated $4 billion in revenue.

Metallurgical production is not expected to resume at any point in 2027. This continuous halt will lead to a $2.6 billion loss in exports and force an additional $1.5 billion in imports of metal products. Consequently, the NBU forecasts a total loss of $7.2 billion in export revenues for the full year of 2027.

Farmers currently hold enough funding to operate until approximately the New Year. However, the sector faces a sharper liquidity crisis in the spring if Black Sea shipping does not restart. The NBU reports that the blockade also adds 0.7 percentage points to annual inflation in 2026.
