The Ukraine trade door opens, but Black Sea insurance narrows it

Why it matters

The agreement makes a 10 billion dollar trade target possible on paper, but the sea route is open only at a price set by insurers. The war risk area widened on 16 September and adds roughly 25,000 dollars a day to a large vessel's Odesa voyage. Ukraine exported only 1.488 million tonnes of grain in September, and alternative routes cost 40–50 dollars more per tonne. Tariffs will not become volume until insurance and port constraints ease. Türkiye's own territorial waters sit outside the area, opening a transhipment opportunity for Turkish ports.

Implications

From 1 October Türkiye removed duties on 10,337 tariff lines for goods from Ukraine; preferential access for Turkish goods begins on 1 January 2027.
On 16 September the war risk area spread to almost the entire Black Sea. A six-day Odesa voyage by a large vessel now carries about 150,000 dollars in extra premium, or 2–3 dollars per tonne of cargo.
Ukraine exported 1.488 million tonnes of grain in September and cut its season forecast from 43 million tonnes to 38–40 million tonnes. The 10 billion dollar target runs into this constraint in 2027.

A door on paper

The Türkiye–Ukraine Free Trade Agreement took effect on 1 October 2026, four years and eight months after it was signed in Kyiv on 3 February 2022. According to AA, the parties are aiming for 10 billion dollars of bilateral trade in the near term. Trade Minister Ömer Bolat's figures, cited by Ekonomi Gazetesi, put trade at 6.6 billion dollars in 2025. Reaching the target would require volume to grow by roughly 52%.

Implementation comes in two stages, and the first three months run in one direction only. According to Interfax-Ukraine, preferential tariffs on Ukrainian exports to Türkiye started on 1 October, while Turkish goods gain preferential entry to Ukraine on 1 January 2027. According to PRM, Türkiye is removing duties on 10,337 tariff lines, around 95% of the goods Ukraine exports. A further 1,348 lines are subject to quotas or reduced duties.

Can the sea that carries the goods be insured?

One institution stands on the other side of the door: the insurance market. According to Beinsure, the London market's Joint War Committee, the body that defines areas where a war risk premium is charged, extended its listed area to most of the Black Sea on 16 September. The 12-mile territorial waters of Türkiye, Bulgaria, Romania and Georgia were left outside. The new terms came into force around 1 October.

The same source says a large vessel pays roughly 25,000 dollars a day in war risk premium on an Odesa voyage. A six-day voyage therefore costs about 150,000 dollars, or 2–3 dollars per tonne of cargo. For a Handysize vessel, a small dry bulk carrier worth about 12 million dollars, the extra premium ranges from 12,000 to 24,000 dollars. Quotes are often valid for only 24 hours, and insurance clubs began sending cancellation notices from 18 September.

The route does not close until the premium becomes unbearable, and at 25,000 dollars a day Odesa is approaching that threshold. The 24-hour quote window turns unpredictability, more than the size of the premium, into a cost. A shipowner cannot sign a contract without knowing the price of the next voyage.

No volume on the port side

Insurance is only one of two constraints. According to UkrAgroConsult, Ukraine exported 1.488 million tonnes of grain and pulses in September, a fall of about 37% on September 2025. On 11 August Ukraine had cut its 2026/27 export forecast from about 43 million tonnes to 38–40 million tonnes. The reason was near-daily attacks on the Greater Odesa ports since late July.

According to an Ag Bull report dated 2 September, the Ukrainian Agrarian Council advised exporters to assume the ports would stay shut until December–January. The same report says the country needs export capacity of 5 million tonnes a month, while alternative routes can carry 2.5 million tonnes. Alternative routes cost 40–50 dollars more per tonne than deep-water ports. On 31 August, 80 ships were waiting to enter the Danube.

What changes for Türkiye

A US Department of Agriculture forecast cited by Türkiye Today says drought could lift Türkiye's 2026 wheat imports by 121% to 7.3 million tonnes. The source does not give the date of this forecast, so the figure may be stale. The same source says Türkiye was the second-largest buyer of Russian wheat after Egypt in October 2025. Russia's Black Sea ports have also been inside the listed area since 16 September.

Agroreview data from December 2025, which is stale, put the war risk premium at 0.65–0.80% of hull value at Russian Black Sea ports and 0.45–0.55% at Ukrainian ports. At Turkish, Romanian and Bulgarian ports it was only 0.10–0.25%. If this gap of three to eight times is preserved because Turkish territorial waters remain outside the area, Turkish ports could emerge as a transhipment point for Black Sea cargo. Current port-level premium data could not be verified as of 3 October.

The real test comes on 1 January 2027. From that date Turkish exporters will gain a tariff advantage in Ukraine, but the ship carrying their goods to Odesa will pay roughly 25,000 dollars a day in premium. The agreement's 10 billion dollar promise will be settled not at the customs desk but on the war risk list in London.

Probabilities

Scenarios

Scenario	Probability	Trigger	Market impact
H1Trade held back by insurance	55%	The war risk area is not narrowed, attacks on Odesa's ports continue and quotes remain valid for only 24 hours.	Trade edges slightly above the 6.6 billion dollars of 2025; the tariff advantage turns into volume only to a limited extent.
H2Turkish ports become a transhipment hub	30%	Turkish territorial waters stay outside the area and part of Ukraine's cargo starts to be transhipped through Turkish ports.	Handling volumes at Turkish ports rise, and the agreement also brings Türkiye logistics revenue.
H3The port front escalates	15%	Attacks spread to open waters near the Turkish coast and insurance clubs narrow cover on voyages to Turkish ports as well.	Trade falls below its 2025 level and the agreement remains on paper.

Second-order effects

And then what?

Starting point

On 1 October the Türkiye–Ukraine free trade agreement took effect, removing duties on 10,337 tariff lines. In the same days almost the whole Black Sea was classed as a war risk area, adding roughly 25,000 dollars a day in extra premium to an Odesa voyage.

1
War risk insurancewithin days
The 24-hour quote window and a 150,000 dollar voyage premium lead shipowners to cut sailings to Ukrainian ports. Ukraine's monthly grain exports stay stuck near September's 1.488 million tonnes.
Watch: Ukraine's October grain export data and any change to the JWC listed area
2
Freight and routingwithin weeks
Cargo shifts to Danube and overland routes that cost 40–50 dollars more per tonne. That cost eats most of the tariff gain Türkiye has granted, so imports from Ukraine rise only modestly despite the agreement.
Watch: TÜİK data on imports from Ukraine for October and November
3
Bilateral trade and portswithin months
When preferential access for Turkish goods begins on 1 January 2027, Turkish exporters pay the same premium to reach Odesa. Trade of 6.6 billion dollars in 2025 cannot approach the 10 billion dollar target in 2027, and Türkiye turns towards a transhipment port role.
Watch: Türkiye–Ukraine foreign trade data for the first quarter of 2027

What breaks the chain

The first link breaks if Türkiye's draft safe navigation arrangement for the Black Sea wins agreement or the Joint War Committee narrows its list. If a state-backed war risk insurance pool removes the uncertainty of 24-hour quotes, the tariff advantage on 10,337 lines could turn into volume.

Triggers

Thresholds to watch

Indicator	Threshold	Today	What it means
Turkish Straits waiting time	Weekly transits down > 10%	—	Would show that the war risk premium has started to curb Black Sea traffic and that the transhipment advantage of Turkish ports is not turning into volume.
USD/TRY	> 50	49.03	A move above 50 would let currency losses erode the tariff gain on inputs imported from Ukraine.
