How Do the Latest Black Sea Attacks Affect Global Food Security?

Center for Strategic and International Studies | Caitlin Welsh, Emma Curtis and Joseph Glauber

Russian military strikes on Ukrainian agricultural infrastructure in the Black Sea and Sea of Azov threaten to inflict up to $3 billion in losses on Ukraine's agricultural sector, driving up global grain prices. These disruptions coincide with severe climate-induced production shortfalls, with the top seven global wheat exporters facing an 11 percent output decline for the 2026/2027 marketing year.

This supply squeeze is exacerbated by the U.S.-Israeli war with Iran and the closure of the Strait of Hormuz, which has disrupted Persian Gulf fertilizer exports and inflated agricultural input costs worldwide. Global food security hangs in the balance. Although Ukraine has exported over 100 million metric tons of grain via its independent maritime corridor since late 2023, Russia's rejection of a mutual Black Sea ceasefire and its targeting of civilian vessels threaten to prolong the crisis indefinitely, leaving net-food-importing nations highly vulnerable to sustained price shocks.

Comment

The disruption of agricultural logistics in the Black Sea demonstrates the extreme vulnerability of commercial shipping corridors to targeted kinetic interdiction. While the Ukrainian Corridor successfully bypassed the restrictive joint inspection regime of the Black Sea Grain Initiative, its operational viability remains entirely dependent on unilateral naval denial capabilities. The relocation of Russia's Black Sea Fleet from Sevastopol to Novorossiysk temporarily eased pressure on Ukraine's western shipping lanes, but it did not eliminate the threat of targeted strikes on port infrastructure.

This vulnerability is compounded by the shifting of Russian fertiliser exports to Baltic Sea ports like Ust-Luga, which are now within range of Ukrainian long-range strike capabilities. Consequently, the complete halt of fertiliser shipments from the southern terminals of Taman and Novorossiysk forces a reliance on these northern routes, exposing them to similar interdiction risks. This geographic consolidation of export infrastructure creates a single point of failure for Russian agricultural logistics at Ust-Luga.

Strategic Question for Discussion

If Ukrainian long-range strike capabilities successfully disrupt fertiliser exports at Ust-Luga, does Russia's logistical pivot to Baltic Sea ports break down, or can alternative overland routes absorb the capacity?

The available evidence suggests that overland rail networks to Asia lack the specialised bulk-handling infrastructure required to fully absorb the export volumes currently routed through Ust-Luga. Consequently, a sustained disruption at this Baltic terminal would likely force Russia to accept severe export curtailments rather than successfully rerouting its fertiliser trade. This bottleneck indicates that maritime access remains an irreplaceable component of Russia's bulk commodity logistics.
