From the Black Sea to the Baltic: Russia’s Grain Trade Finds New Routes

Russian companies are repurposing Baltic and Arctic terminals to export grain traditionally shipped through the Black Sea. As attacks disrupt southern ports and shipping routes, the resulting shift is placing new demands on rail networks, bulk terminals and northern maritime infrastructure—and changing the commercial geography of one of the world's most important agricultural export systems.

Russia's grain export industry is beginning to reorganise around a problem that investment in its traditional southern ports cannot immediately resolve: the growing vulnerability of the Black Sea to military attacks. As the conflict increasingly affects commercial shipping, terminals and supporting infrastructure, Russian exporters are moving grain towards Baltic and Arctic ports, converting existing facilities and redirecting rail freight across the country.

The scale of this change is significant. According to a Reuters investigation published on 21 September, almost 90% of Russia's seaborne grain exports travelled through the Black Sea during the previous export season. That concentration provided considerable commercial advantages, connecting Russia's principal agricultural regions with large export terminals and established shipping services serving the Mediterranean, Middle East, North Africa and Asian markets.

It has also created a substantial vulnerability.

Ukrainian drone attacks on Russian vessels and port infrastructure, alongside Russian strikes against Ukrainian agricultural terminals and shipping, have sharply disrupted exports from both countries. The Center for Strategic and International Studies examined the consequences in a September assessment, highlighting how attacks against maritime infrastructure have expanded the conflict's effects on agricultural trade and international food security.

For Russia, the immediate response has been to exploit infrastructure originally designed for other commodities. Fertiliser and coal terminals in the Baltic and Arctic are being adapted to accommodate grain, while railway operators and exporters adjust their logistics to reach these alternative outlets.

The development illustrates a wider consequence of the conflict. Maritime disruption in one region is reshaping the economics of transport infrastructure hundreds, and sometimes thousands, of kilometres away. The challenge is no longer confined to keeping individual ports operational. It is becoming a question of whether an entirely different network of railways, storage facilities and maritime terminals can absorb the cargo previously handled by the Black Sea.

The Black Sea's export advantage is becoming a vulnerability

Russia's southern grain export network developed around geography, production and established commercial relationships. The Black Sea ports of Novorossiysk, Tuapse and Taman, together with facilities in the Sea of Azov, provide access to important agricultural production regions and relatively direct maritime connections to major importing countries.

That infrastructure cannot easily be replicated elsewhere. Grain exports depend on specialised storage, handling equipment, railway access, loading capacity and the availability of suitable bulk carriers. The proximity of southern ports to Russia's principal grain-producing regions has historically helped exporters minimise inland transport costs and maintain competitive prices in international markets.

But military attacks are undermining those advantages. The escalation of attacks against commercial vessels and ports in September has introduced additional uncertainty into freight availability, insurance, terminal operations and shipping schedules. Attacks have also affected vessels beyond the immediate conflict area, including damaged merchant ships that subsequently drifted or grounded along the Turkish coast.

The economic implications extend well beyond Russia. Ukraine has also experienced severe disruption to agricultural exports following attacks against its Black Sea infrastructure. Both countries remain major suppliers to international wheat markets, making sustained interruptions particularly consequential for import-dependent economies.

Russia's response reflects the difficulty of replacing established export capacity during an active conflict. Rather than waiting for new grain terminals to be constructed, companies are adapting existing infrastructure and redirecting cargo towards ports with available handling capacity.

This approach can preserve some export activity, but it changes the economics of every stage of the supply chain.

Ust-Luga and St Petersburg: Russia's Baltic alternatives

The Baltic is emerging as an important alternative for Russian grain exporters. Its established port infrastructure, railway connections and access to international maritime routes make it a relatively practical destination for cargo diverted away from the Black Sea.

Ust-Luga is particularly significant. Reuters reports that the privately operated Ultramar terminal, traditionally specialising in mineral fertilisers, has been adapted to accommodate grain shipments. The terminal has a declared annual handling capacity of 37 million tonnes, although that figure represents its overall facility capacity and should not be interpreted as available grain-handling capacity.

The distinction is important. Converting existing infrastructure provides an opportunity to introduce new cargoes without constructing an entirely new terminal, but fertilisers and grain have different handling, storage and contamination-control requirements. The availability of berth capacity does not necessarily mean that equivalent grain export capacity can be introduced immediately.

Nevertheless, the conversion demonstrates how Russia's established fertiliser export infrastructure can provide flexibility during periods of disruption. Reuters also reports that the Modul terminal in St Petersburg has begun accommodating grain shipments, while major traders, including Demetra, are adjusting their export operations towards northern and western gateways.

The commercial implications extend into Russia's railway network. Cargo traditionally moving towards southern export terminals must now travel west or northwest, competing for access to infrastructure serving fertilisers, coal, metals, containers and other commodities. This raises questions about wagon availability, railway tariffs, terminal scheduling and the additional costs of moving grain over greater distances.

The Baltic also introduces different maritime considerations. Cargoes destined for traditional buyers in the eastern Mediterranean or North Africa may face longer voyages than equivalent shipments from Novorossiysk. Exporters must therefore weigh the reduced exposure to Black Sea disruption against additional transport costs and the ability to secure competitively priced shipping.

These costs will influence which cargoes can be diverted economically and which customers can be served through alternative ports.

Murmansk and the northern option

Further north, Murmansk is gaining attention as Russia looks to reduce its dependence on southern maritime routes. Located on the Kola Peninsula, the port has an important geographical advantage: its ice-free access to the Barents Sea allows maritime operations throughout the year.

According to the Reuters investigation into the shift towards Baltic and Arctic ports, facilities in Murmansk are also beginning to handle grain as exporters seek alternative routes that are further removed from the main Black Sea conflict zone.

Murmansk's attraction is partly strategic. Vessels leaving the port can access the Norwegian Sea and North Atlantic without passing through the Black Sea or the Baltic's Danish straits. That provides a different route to international markets and reduces reliance on any single maritime gateway.

However, northern access does not eliminate logistical constraints.

Murmansk lies much further from Russia's principal agricultural production regions than its southern ports. Diverting substantial quantities of grain to the Arctic requires extended railway movements, sufficient rolling stock and storage facilities capable of maintaining reliable loading schedules. Additional inland transport costs must then be considered alongside maritime freight rates and the distance to destination markets.

While Murmansk's year-round maritime access is an advantage, its ability to become a substantial grain export centre will depend on the economics of the entire corridor rather than the characteristics of the port alone.

The development also warrants attention to other northern Russian facilities, including Arkhangelsk, although reported grain-handling conversions at Murmansk should not be taken as evidence of equivalent operational capacity elsewhere in the Arctic.

For exporters, northern ports may initially provide additional flexibility rather than a direct replacement for the Black Sea. Their longer-term importance will depend on sustained demand, investment in specialised handling facilities and the ability of railway operators to deliver cargo competitively.

The railway network is becoming the next bottleneck

Russia's efforts to diversify grain exports demonstrate why port capacity cannot be assessed independently of inland transport.

Grain redirected to Ust-Luga, St Petersburg or Murmansk must be delivered through railway networks serving other major industrial and commodity flows. Fertilisers, coal, metals and containers already place substantial demands on these routes, particularly where railway access is concentrated around major industrial centres and port complexes.

The shift creates an additional layer of competition for infrastructure. Prioritising grain movements may help exporters maintain shipments, but it can also affect the availability of railway capacity for other commodities. The commercial consequences will depend on the volumes redirected, the duration of Black Sea disruption and the ability of railway operators to introduce additional services.

Russia has reportedly introduced measures to support alternative export routes, including railway prioritisation and government assistance. Such interventions can help maintain export flows during exceptional disruption, but they do not eliminate the underlying costs of longer journeys or additional cargo handling.

The impact on fertiliser and coal logistics is also worth monitoring. Although Reuters' industry sources suggested that available spare capacity could limit the immediate effect of terminal conversions on fertiliser shipments, sustained grain movements would introduce another commodity competing for access to established bulk infrastructure.

For port operators and logistics providers, the key question is whether these changes represent a temporary response to conflict or the beginning of a more permanent redistribution of Russian export traffic.

The commercial consequences extend beyond Russia

The effects of changing Russian grain routes will be felt in shipping markets and importing countries, particularly across the Mediterranean, Middle East and North Africa.

Exporters diverting cargo from the Black Sea to the Baltic or Arctic must account for additional railway costs, different voyage distances, terminal charges and potentially different vessel availability. Depending on destination, the alternative route could also require additional sailing time and expose cargoes to different weather and operational conditions.

For importers, the immediate concern is reliability. Longer or less predictable supply chains complicate procurement, inventory management and delivery scheduling, particularly for countries dependent on large volumes of imported wheat.

The disruption is occurring amid wider uncertainty in agricultural markets. As CSIS observed in its assessment of the latest Black Sea attacks, the targeting of agricultural export infrastructure has consequences for global food security that extend beyond the immediate military confrontation.

The northern redistribution of Russian grain also carries implications for dry bulk shipping. A lasting change in export geography could alter vessel deployment, voyage distances and demand across different bulk carrier segments. But the outcome will depend on whether alternative ports can generate sustained volumes rather than accommodate occasional cargoes during periods of acute disruption.

If the Baltic and Arctic become established components of Russia's grain export system, the resulting changes could affect the balance between southern and northern port investment long after the immediate disruption subsides.

What businesses should monitor

The development of Russia's alternative grain export network should be assessed through actual cargo movements rather than announced terminal capacity alone. Ust-Luga and St Petersburg will provide early indications of whether converted bulk facilities can maintain regular grain shipments alongside their existing commodity operations. Grain volumes, vessel calls, storage availability and the consistency of railway deliveries will help establish whether the Baltic is becoming a dependable export alternative.

Murmansk presents a different set of indicators. The volume of grain arriving by rail, terminal adaptation, vessel loading frequency and the cost of serving traditional importing markets will determine whether its northern location offers a sustainable commercial advantage. Its strategic distance from the Black Sea must be weighed against longer inland routes and additional logistical complexity.

Developments in the southern ports remain equally important. Any improvement or deterioration in operating conditions at Russia's Black Sea export terminals will influence the economics of northern diversion. At the same time, continued attacks against Ukrainian agricultural infrastructure could prolong disruption across the wider Black Sea grain market.

Exporters, traders and freight operators should also monitor the effects on Russia's other bulk commodities. Competition for railway capacity and terminal access could create secondary pressures on fertiliser, coal and industrial cargoes even where the converted facilities themselves retain spare capacity.

The most revealing indicator will be whether diverted grain movements become consistent enough to support regular shipping services and long-term commercial contracts.

A changing geography of export risk

Russia's move towards Baltic and Arctic grain exports illustrates how an extended conflict can progressively reorganise national transport networks. Infrastructure originally developed for fertilisers, coal and other bulk commodities is being adapted to accommodate agricultural cargo as the country's traditional southern export system faces increasing disruption.

But geographical diversification does not automatically produce resilience. Moving grain through alternative ports requires dependable inland connections, suitable storage and handling facilities, competitive maritime services and sufficient capacity to absorb seasonal export volumes.

The Black Sea retains considerable structural advantages, particularly its proximity to Russia's principal grain-producing regions and established markets. Replacing those advantages through northern routes will involve additional investment, longer transport distances and more complex logistics.

For businesses involved in agricultural trade, shipping and infrastructure investment, the question is therefore not whether Russia can move some grain through the Baltic and Arctic. It is how much cargo those alternative networks can accommodate, at what cost and for how long.

The conflict is changing more than the security environment of the Black Sea. It is beginning to reshape the railway networks, ports and commercial relationships through which Russian agricultural exports reach international markets.
