Volodymyr Zelensky says Russia is not yet prepared to agree to a stand-alone Black Sea ceasefire protecting ships carrying agricultural products. According to the Ukrainian president, Moscow is trying to link the safety of food exports to an end to Kyiv’s strikes on Russian energy infrastructure.
Ukraine is proposing a narrower arrangement. Zelensky said he had spoken with several foreign leaders about using vessels from their countries to move food from Ukrainian ports. Kyiv, he added, would also refrain from attacking those ships if they entered Russian ports to collect agricultural exports.
Moscow, according to Zelensky, is seeking a broader bargain. Russia would halt attacks on Ukraine’s grain corridor if Ukraine stopped targeting Russian oil refineries, pipelines and other energy assets. Kyiv argues that these two categories of targets are fundamentally different in both purpose and military value.
If the negotiations are expanded to cover energy, Ukraine says reciprocity would be essential. Zelensky has argued that Kyiv could discuss suspending strikes on Russian oil and fuel infrastructure only if Moscow simultaneously stopped attacking Ukraine’s electricity generation, transmission network and heating system.
Daycom’s analysis indicates that the proposed Black Sea ceasefire has become an argument over the boundaries of economic warfare. Ukraine wants civilian food shipping treated as a protected category. Russia is trying to use that protection as leverage to shield an energy sector of far greater financial importance to Moscow.
The dispute therefore extends well beyond grain. Ukraine has intensified strikes on Russian refineries, fuel logistics, ports and other economic targets in recent weeks, seeking to increase the cost of the war and constrain the infrastructure that supplies both the Russian military and the wider wartime economy.
Russia, meanwhile, has increasingly connected attacks on Ukrainian ports with strikes against its own commercial infrastructure. Moscow has argued that it sees little value in partial arrangements that would reduce pressure on Ukrainian exports while leaving Kyiv free to continue hitting Russian energy and transport facilities.
That position was already visible in mid-August, when reports emerged that Ukraine had proposed a mutual halt to attacks on civilian targets in the Black Sea. Russian officials dismissed the idea of a limited arrangement and signalled that they would prefer negotiations to cover a much wider set of economic targets.
For Kyiv, the problem is the logic of the exchange itself. Ukrainian officials argue that civilian vessels carrying grain or other food products should not become bargaining chips for the protection of facilities that generate export revenue, supply fuel and support Russia’s broader capacity to sustain the war.
Moscow sees the issue differently. Russia regards attacks on refineries, Novorossiysk and transport infrastructure as a campaign against its economy. It therefore treats restraint in the Black Sea as a concession that should be matched by Ukrainian limits on strikes against strategically important Russian assets.
The urgency of the talks is explained partly by the damage to Ukrainian exports. A series of Russian attacks on port infrastructure in late July and early August sharply reduced the volume of agricultural shipments. For an economy still dependent on maritime trade, even a few weeks of disruption carry serious consequences.
The timing is particularly difficult during the harvest. Grain has to move from farms to elevators and then to export terminals. If port capacity is constrained, storage fills up, domestic prices fall and farmers receive less working capital for fuel, salaries and preparations for the next planting season.
Alternative routes can absorb only part of the pressure. Danube ports have more limited capacity, while low water levels can further restrict navigation. Rail and road routes through the European Union are more expensive and less efficient for bulk, relatively low-margin cargoes such as wheat and maize.
That is why Ukraine’s own maritime corridor has become so important. After Russia withdrew from the UN- and Turkey-brokered grain deal in 2023, Kyiv gradually restored large-scale commercial shipping through the Greater Odesa ports without formal Russian participation.
Over the following years, hundreds of millions of tonnes of cargo moved through the route, including vast quantities of grain. By 2026, maritime ports once again handled the overwhelming share of Ukraine’s agricultural exports, making any disruption immediately significant for farmers, state revenues and foreign buyers.
The international dimension turns the Black Sea into a problem far beyond the two belligerents. Ukraine and Russia remain major suppliers of wheat, maize and oilseeds. For several countries in the Middle East and North Africa, disruptions in their exports can quickly translate into higher import costs and greater food insecurity.
Markets react rapidly when shipping is interrupted. Buyers begin looking to Australia, Argentina, North America and other suppliers, but replacement grain often comes with higher commodity and freight costs. Those expenses eventually reach consumers in countries that have no direct role in the war.
Russian exports are vulnerable as well. Ukrainian strikes on Novorossiysk and other facilities have disrupted port operations, oil terminals and infrastructure used for commercial shipments. For Moscow, Black Sea security is therefore as much an economic concern as a military one.
Ukraine has shown a growing willingness to strike Russian economic targets more deeply and more frequently. The list includes refineries, fuel depots, transport hubs and port infrastructure that Kyiv says contribute to Russia’s ability to finance and sustain its military campaign.
Against that backdrop, Zelensky’s proposal involving third-country vessels has a distinct diplomatic logic. If ships belonging to or backed by neutral states collect food from Ukrainian or Russian ports under mutual guarantees, violating the arrangement would impose a much higher political cost on whichever side attacked them.
But such a system would require more than verbal assurances. The parties would have to decide which ships qualify for protection, who verifies cargoes, which routes are considered safe and what happens when a commercial port also supports infrastructure with potential military or dual-use functions.
Without a verification mechanism, every incident could trigger a new dispute over whether a target was truly civilian. Similar disagreements have weakened previous attempts to regulate Black Sea trade, even when international mediators were directly involved.
Turkey remains the most obvious intermediary. It controls access between the Black Sea and the Mediterranean, maintains working relationships with both Kyiv and Moscow and previously helped broker the 2022 grain initiative alongside the United Nations.
That earlier agreement restored Ukrainian agricultural exports through several ports, but Russia withdrew in July 2023, arguing that commitments relating to its own exports had not been fulfilled. Ukraine then built an alternative shipping route that functioned without Moscow’s formal consent.
The route’s survival depended on a combination of Ukrainian military pressure in the western Black Sea, commercial insurance, shipowners willing to accept risk and navigation close to Romania and Bulgaria. Its success demonstrated that trade could continue, but only while private operators believed the danger remained manageable.
That makes confidence among shipping companies decisive. Owners assess insurance premiums, risks to crews, potential damage to vessels and the likelihood of delays. One major strike can alter those calculations faster than diplomatic statements and cause carriers to suspend calls to Ukrainian ports.
In 2026, pressure has risen from both directions. Russia has intensified attacks on Ukrainian port and shipping infrastructure, while Ukraine has widened strikes on Russian economic assets. The Black Sea increasingly resembles an extension of the battlefield rather than a neutral commercial space.
The central question is now which parts of that economic contest the two sides are willing to place off limits. Kyiv wants a protected category for food trade. Moscow wants reciprocal restrictions extended to Russian energy infrastructure, a sector with far greater strategic and financial value.
For Ukraine, that condition is especially sensitive after a winter in which Russian attacks on power stations, substations and heating infrastructure repeatedly left millions without electricity and heat. Kyiv does not want to give up strikes on refineries while Moscow retains freedom to attack Ukraine’s energy system.
From a military perspective, the categories are also different. Refineries and fuel logistics can contribute directly to Russia’s war economy and military supply. A merchant vessel carrying commercial food exports performs a primarily civilian economic function, even if the broader infrastructure around ports can sometimes have dual uses.
The distinction becomes less clear in practice. Ports handle multiple types of cargo, transport networks may serve both civilian and state needs, and the same infrastructure can support commercial and military logistics. These ambiguities are precisely where the hardest legal and political arguments begin.
Zelensky’s latest remarks suggest that Kyiv is not rejecting broader limitations in principle, but insists they must be symmetrical. If Ukraine stops attacking Russian oil and fuel infrastructure, then Russia, in Kyiv’s view, must also end strikes on Ukrainian power generation, grids and other energy facilities.
Moscow had not publicly accepted that formula by the time of Zelensky’s statement. The Kremlin said only that measures were being taken to reduce the impact of Ukrainian strikes on Russian grain exports, leaving the possibility of a maritime arrangement open but offering little evidence of an imminent compromise.
For major grain importers, the incentive to reach some form of agreement is obvious. The longer Black Sea exports are disrupted, the higher the costs of freight, insurance and commodities become. The economic consequences of the war are then transferred to countries dependent on imported food.
That gives Kyiv a diplomatic argument of its own. Ukraine is trying to frame protected grain shipping not as a bilateral concession to Russia, but as an international interest. The more third countries are directly involved in the movement of food, the more politically costly an attack on those vessels becomes.
Russia retains its own leverage: the ability to threaten maritime infrastructure on which a large part of Ukraine’s trade depends. Moscow is attempting to exchange restraint in that area for limits on Ukraine’s campaign against oil and gas assets, which remain central to Russian revenues.
That is why grain and oil have ended up at the same negotiating table. The dispute is no longer simply about whether the next vessel can leave Odesa or Novorossiysk. It is about the rules of economic warfare — which flows are treated as protected, and which remain legitimate instruments of pressure.
A limited Black Sea ceasefire could still become one of the few practical agreements possible before the broader war ends. It could reduce risks to crews, lower insurance costs and restore some predictability without forcing either side to resolve territorial or political questions first.
But the present dispute shows why even a narrow deal is difficult. To protect ships carrying wheat and maize, Kyiv and Moscow would have to agree not only on navigation, but on where civilian trade ends and the economic infrastructure of war begins.
