EditBlack Sea shipping risks on the rise as importers await Russian, Ukrainian grain
The risk of reduced grain exports, rising logistics costs and tighter terminal capacity threaten to push global wheat prices higher
Restrictions on vessel movements in the Sea of Azov, imposed after Ukrainian drone attacks on commercial shipping, have redirected a substantial share of Russian grain cargo toward the deep-water terminals of Novorossiysk and Taman in the Black Sea.
The resulting surge in truck and rail deliveries has exposed bottlenecks in the inland logistics network that underpins Russia’s position as the world’s leading wheat supplier. What began as a maritime security problem has become a test of supply-chain resilience at a moment when the new harvest is entering the market.
Around a quarter of Russia’s seaborne grain exports used to move through the shallow waters of the Sea of Azov. Following attacks on vessels and the subsequent suspension of movements in the region, this summer the Russian authorities have pushed exporters to reroute grain from southern production areas by road and rail to the larger Black Sea ports. Terminals such as NZT and KSK in Novorossiysk and ZTKT in Taman, which together can handle more than 20 million tonnes annually, have responded by restricting truck intakes. Congestion has lengthened queues, slowed loading, and raised handling costs. Overnight navigation bans at Novorossiysk, introduced after further drone threats, have further reduced operational flexibility, leaving the system with less capacity to absorb delays or sudden changes in cargo volume.
The port of Kavkaz, previously used to transship grain from smaller Azov vessels onto larger ships, closed almost immediately after the July restrictions. Meanwhile, attacks have also reached Black Sea infrastructure, including facilities linked to the Caspian Pipeline Consortium near Novorossiysk.

A Russian-flagged vessel was sunk in a separate incident, underscoring the widening geographic scope of risk. Although grain continues to leave Russian ports, the concentration of flows onto fewer routes has made the export system more vulnerable to disruption.
Higher costs and limited alternatives strain export flexibility
Rerouting grain inland is not cost-free. Additional truck and rail journeys increase transport expenses, while Russian rail operators have been considering higher tariffs. The two major Novorossiysk terminals still accept rail deliveries, but only from southern regions, and roughly a third of their volume previously arrived by truck. ZTKT relies exclusively on road transport. The result is rising logistics costs that exporters must either absorb or pass on. Russian consultancy IKAR cut its July wheat export forecast from 2.5 million to 2 million tonnes after Azov shipping halted, illustrating how quickly expectations can adjust when inland movement falters.
Alternative outlets exist but offer little relief at scale. Baltic ports are viewed as the safest longer-term option, yet they involve greater distances and higher freight costs. The Caspian Sea route serves primarily Iranian demand and has seen no meaningful increase since mid-July; risks there have also risen amid broader regional tensions. Inland waterways cannot replace the volumes normally shipped through the Azov and Black Sea. Consequently, Russia’s export system is operating with reduced flexibility just as the new crop arrives. Domestic stocks could build if grain cannot move efficiently to ports, while international buyers face higher offers and longer delivery times.
Pressure on grain exports is no longer limited to the open sea
Russia remains the dominant wheat exporter, and its Black Sea terminals are the primary gateway for shipments to the Middle East and North Africa. Turkey depends heavily on Russian wheat for its milling industry and flour exports; Egypt and Iran rank among the largest importers. No outright halt in exports has occurred, yet higher freight rates, elevated insurance premiums, and extended transit times are already lifting import costs and eroding supply-chain predictability.

The disruption coincides with Russian attacks on Ukrainian ports as that country begins harvesting an estimated 22–23 million tonnes of wheat. Buyers are therefore assessing risks to two of the region’s largest suppliers simultaneously. Market reaction has been sharp. Chicago wheat futures gained roughly 50 cents and Paris wheat rose about €17 in the immediate aftermath, yet physical trade remained relatively subdued. Much of the rally appears driven by investment funds covering short positions rather than a surge in end-user demand. Black Sea bids and offers moved higher, but concluded business stayed limited.
Grain continues to leave Russian ports, but those are not considered unsafe. The risk of reduced grain exports could add yet another layer of crisis on top of existing pressures.
