• Russia could restore roughly 80% of its Black Sea–Sea of Azov grain-port capacity swiftly if a credible maritime ceasefire or safe-navigation agreement is reached, according to industry sources.
  • However, three key terminals—including Novorossiysk and Taman—are badly damaged and will require months of repairs, creating a serious bottleneck.
  • The disruption has already slashed Russian grain exports by 31% year-on-year in July–August, with September volumes estimated at roughly half of last year’s level, while global wheat prices have climbed 15%.

Efforts to revive Russia’s Black Sea grain exports have hit a snag: while most of the region’s port infrastructure could be brought back online quickly if a maritime ceasefire takes hold, three major terminals are so badly damaged that repairs will take months, according to industry sources and an analysis of port data.

The assessment, based on data from industry sources, shows that Russia could immediately restart about 80% of its grain trading capacity in the Black Sea and Sea of Azov if diplomatic efforts to reopen the corridor succeed. But the remaining 20%—concentrated at key terminals around Novorossiysk and Taman—will remain offline for months, severely limiting the country’s ability to ship grain during the critical post-harvest export season.

A Fragile Ceasefire

The disruption stems from a summer escalation in reciprocal attacks on commercial shipping and export infrastructure. Ukraine’s July attack on the Taman grain terminal and its August 12 strike on Novorossiysk halted operations at Novorossiysk’s three main grain terminals.

Novorossiysk is especially consequential: it normally accounts for about 40% of Russian grain exports, while Black Sea and Sea of Azov ports handled nearly 90% of Russia’s seaborne grain exports in the previous export season.

The damage is uneven. NKHP/Novorossiysk Bread Products Plant indicated that repairs could require up to four months; the Demetra-owned terminal suffered less significant damage, while the Delo Group’s KSK terminal had suspended operations largely amid security concerns rather than confirmed equivalent structural damage.

Turkey is pursuing diplomatic proposals with both Russia and Ukraine for safer Black Sea shipping, according to people familiar with the matter. Yet a prior Ukrainian proposal for the sides to stop attacking civilian Black Sea targets was rejected by Russia, and the parties remain divided over what a ceasefire should cover.

“What institutional investors like us are really focused on is regulatory stability,” said Andrea Valeri, Blackstone (BX)’s country chairman for Italy, speaking at a separate event. “Italy in this regard has been on a very steady growth trajectory.” His comments underscore the broader appetite for predictability that is now missing in the Black Sea.

Export Volumes Plunge

The immediate market impact has been severe. Russia exported 4.4 million tonnes of grain in July–August, about 31% below a year earlier, according to industry data. September exports were estimated at 2.45 million tonnes, roughly half the prior-year level.

Grain inventories are accumulating inland, reducing cash flow and storage capacity for producers during the post-harvest export season. Farmers in Krasnodar, a core agricultural region, are facing delayed sales and falling farm-gate returns; local authorities declared a state of emergency over drone-related export disruption, enabling compensation for affected parties.

Global wheat markets are also feeling the pinch. Russia and Ukraine together account for about 27% of global wheat exports. FAO data cited by CSIS put world wheat prices 15% higher in August 2026 than a year earlier, with supply interruptions transmitted rapidly into flour, bread, feed, and food-import bills.

Russia is redirecting grain via Baltic, Caspian, Arctic, and Far Eastern routes, including converted terminals at Ust-Luga and prospective shipments from Murmansk. At Ust-Luga, the Ultramar fertilizer terminal began handling grain in August; rail applications for September shipments reached about 260,000 tonnes, with cargo headed for Egypt and Saudi Arabia. Murmansk is preparing to begin grain exports in October, and Russian Railways approved an initial 40,000-tonne shipment from Stavropol.

But these routes cannot fully substitute for southern ports: existing Baltic grain capacity is estimated at 2–7 million tonnes, versus more than 60 million tonnes at southern ports. Rail hauls and longer voyages make rerouting more costly; containerized loading at some Baltic facilities is particularly expensive.

Diplomatic Stakes

The political issue is whether Russia and Ukraine can separate civilian shipping and agricultural infrastructure from the broader war. Turkey has positioned itself as a mediator and is working with both sides on proposals for Black Sea shipping, while the EU, France, Romania, and Ukraine have publicly called for a moratorium on attacks in the Black Sea and a broader ceasefire.

This follows the collapse of the UN- and Turkey-brokered Black Sea Grain Initiative in July 2023. The arrangement had enabled Ukrainian agricultural exports under inspection rules, but Russia argued that the agreement did not adequately facilitate its own food and fertilizer exports. Following its end, Ukraine developed its own maritime corridor, through which it exported roughly 100 million tonnes of grain by January 2026; the current escalation has now impaired both countries’ trade simultaneously.

The diplomatic stakes extend beyond the two belligerents. Food-importing countries, particularly across Africa, the Middle East, and parts of Asia, are exposed to higher import costs and less reliable supply. European states face spillover through higher food prices, pressure on rail and port alternatives, and threats to navigation near Romania and the western Black Sea.

Outlook

Near term, a workable diplomatic agreement could permit a rapid operational restart at many undamaged or lightly damaged facilities—consistent with the 80% estimate—but actual throughput would depend on demining or safe-navigation arrangements, vessel availability, insurance, crew willingness, and assurance that attacks will not resume. The heavily damaged terminals would continue to constrain capacity during repairs.

If diplomacy fails, Russia is likely to expand its Baltic and Arctic workaround. That will cushion the shock, but it is unlikely to restore normal southern export volumes soon. A converted terminal network relies on rail capacity, subsidy support, compatible loading equipment, and longer supply chains; it also shifts security exposure toward the Baltic and Arctic routes.

Longer term, the crisis may accelerate a durable redesign of regional grain logistics: greater investment in non-Black Sea Russian export routes, more Ukrainian reliance on rail, Danube, and European port connections, higher maritime insurance and freight premiums around the Black Sea, and more volatile wheat and fertilizer prices.

The broader market backdrop is unusually fragile. The disruptions coincide with drought and other weather-related production challenges among major wheat exporters; USDA projections cited by CSIS point to an 11% decline in output among the top seven wheat exporters in the 2026/27 marketing year. That means a Black Sea reopening would have outsized value for global food security, while further attacks could produce a disproportionate price response.

A spokesperson for the Russian grain union did not respond to a request for comment. The Ukrainian agriculture ministry declined to comment on the status of ceasefire negotiations.

Correction: An earlier version of this article misstated the percentage of Russian grain exports normally handled by Novorossiysk. It is about 40%, not 50%.
