Black Sea attacks disrupt grain shipments, driving wheat prices to three-year high

Tit-for-tat military strikes by Russia and Ukraine on Black Sea ports and commercial vessels have severely disrupted global grain shipments, driving Chicago wheat futures up by over 17% since early July 2026. The escalating blockade has halted Ukraine's maritime exports, threatening to halve its agricultural revenues and cause up to $12 billion in losses. Major importers like Egypt and Indonesia face severe food security risks, forcing global buyers to seek costlier alternative supplies from Australia and North America.

Black Sea grain infrastructure attacks

• ▪At least five grain ships, including the Victoria V, Fehu, Elina B, Necibe, and Anna S, were struck by drones near the Russian Black Sea ports of Novorossiysk and Tuapse on August 17 and 18, 2026.
• ▪In July 2026, Ukraine recorded 35 attacks on vessels in port, 22 at sea, and 67 on port facilities, compared to 14 total incidents in 2025.
• ▪Tit-for-tat attacks by Russia and Ukraine on Black Sea ports and vessels in August 2026 have shuttered grain terminals and forced shippers to delay or cancel loadings.

Global wheat price surge

• ▪Benchmark Chicago wheat futures have climbed more than 17% since the start of July 2026, driven by disruptions to Black Sea grain exports.
• ▪The Bloomberg Agriculture Spot Index has broken out, signaling rising inflationary pressures across raw agricultural commodities in August 2026.
• ▪Disruptions to Black Sea and Sea of Azov ports could reduce global grain supplies in 2026 by 86 million tonnes, representing approximately 17% of global exports.

Ukraine economic resilience factors

• ▪Total grain shipments from Ukraine since the start of August 2026 have dropped to approximately 500,000 tons, representing about 20% of the country's potential export capacity.
• ▪The Russian Foreign Ministry formally rejected a Turkish-mediated proposal in August 2026 to establish a mutual ceasefire on civilian shipping in the Black Sea.
• ▪Ukraine risks losing half of its agricultural exports, amounting to at least 30 million tons and between $10 billion and $12 billion in revenue, due to the Odesa port blockade.

Food security risks for importers

• ▪Indonesia, the world's second-largest wheat buyer, has contracted for 600,000 tons of grain from former Soviet exporters for delivery between July and September 2026.
• ▪Egypt, the world's largest wheat importer, sourced more than 82% of its wheat imports from Russia and Ukraine during the first half of 2026.
• ▪Jordan cancelled two wheat tenders and two barley tenders in August 2026 due to high prices, shipping risks, and a lack of competitive offers.

Shift to alternative grain suppliers

• ▪Asian grain processors have booked 2.0 million to 2.5 million tons of Black Sea wheat for arrival between July and September 2026, representing 30% to 50% of regional import demand.
• ▪Australian Premium White wheat is quoted at $315 to $320 per ton to Asia, compared to Black Sea cargoes priced between $260 and $280 per ton.
• ▪Importers are seeking alternative grain supplies from Australia, North America, and Argentina, which trade at higher prices than Black Sea cargoes.
