Global wheat purchasers are confronting tighter supplies as a recent spate of attacks on Black Sea grain infrastructure has interrupted shipments during a critical export window. Market prices are responding, with benchmark Chicago futures up by more than 17% since the start of July, and physical wheat values advancing in rival exporting regions including Argentina, Australia and the United States.
Industry participants say a sequence of retaliatory strikes by Russian and Ukrainian forces on ports and vessels has effectively forced the shutdown of some grain terminals and led shippers to postpone or cancel loading operations for dozens of cargoes during the season when exports typically peak.
"The cargoes were due to start arriving from mid-August, but many ships could not go in to load," said a Singapore-based trader who sells Black Sea wheat to millers in Asia. "Buyers are thinking about replacing some of these cargoes with other origins, such as Australia, North America and Argentina." The trader spoke on condition of anonymity because they were not authorised to speak to media.
Reliance on Black Sea supplies
Most large importers rely on Black Sea wheat for a significant portion of their second-half supply, when newly harvested grain typically reaches the market from July onwards. Two Singapore-based traders estimated that processors in Asia had booked roughly 2.0 million to 2.5 million tons of Black Sea wheat for arrival between July and September, equivalent to about 30% to 50% of import demand in that period. Both traders requested anonymity.
With fears mounting that several of those shipments may not arrive on schedule, market participants are looking for replacements. "By the end of August, the market will have to find solutions," said Maxence Devillers, a grain analyst at Argus Media.
Some regional harvest outcomes have softened the immediate impact. Stronger-than-expected crops in parts of the Middle East and North Africa have provided temporary relief, with the Egyptian government buying record amounts of local wheat and improved rainfall improving prospects in Morocco and Tunisia.
Top buyers under pressure
Egypt, the world's largest wheat importer, sourced more than 82% of its wheat imports from Russia and Ukraine in the first half of 2026. Traders say the private sector in Egypt, which handles more than half of the country's wheat imports and typically maintains smaller inventories, is facing the most acute pressure.
Indonesia, the second-largest buyer, has contracted about 600,000 tons to be shipped from former Soviet exporters in the July-September period, according to traders. An official from the Indonesian Flour Millers Association said current stocks can meet immediate food-grade wheat requirements, but cautioned that supplies are not abundant. "We have to look at other origins such as Bulgaria, Australia, Romania, and Argentina for cargoes that do not get shipped from Russia and Ukraine," the official said.
Other significant importers dependent on Russian and Ukrainian supplies include Algeria, Bangladesh, Jordan, Thailand, Tunisia and Vietnam. Jordan cancelled two wheat tenders and two barley tenders this month after receiving few offers, with traders citing elevated prices and shipping risks. Tunisia has warned suppliers against invoking force majeure.
Loading delays and rising costs for alternatives
Operational disruptions have included direct attacks on vessels. Last week a ship slated to load grain for Egypt was struck while approaching Russia's Novorossiysk port, three people familiar with the matter said. Two of those sources identified the vessel as the Xin Hai Tong 66, noting it was unladen and that no injuries were reported.
Few shipowners are currently willing to call at Russian or Ukrainian ports, contributing to additional delays. "The situation is getting worse by the day," said Hesham Soliman, a trader based in the Egyptian port of Alexandria, adding that a shortage could materialise if the situation is not resolved.
Shifting shipments to alternate origins will raise costs. Australian Premium White wheat is trading at around $315 to $320 a ton including cost and freight to Asia, compared with about $305 a ton for the cheapest U.S. wheat. Most Black Sea cargoes are valued at roughly $260 to $280 per ton, meaning replacement supplies are materially pricier for buyers.
Scale of attacks and fears for food security
Recent weeks have seen the breakdown of an arrangement that previously shielded grain ships and port terminals in Russia and Ukraine from attacks, enabling both countries to sustain large agricultural exports. Official counts cited by Ukrainian authorities showed that in July there were 35 attacks on vessels in port, 22 attacks at sea, and 67 attacks on port facilities. By comparison, the figure for all of 2025 was 14.
The threat to food supplies has attracted high-level attention. Ukrainian President Volodymyr Zelenskiy said he raised the food supply risks stemming from Black Sea attacks in discussions with Egyptian President Abdel Fattah al-Sisi.
Market outlook
With a significant share of second-half shipments vulnerable to disruption, traders and buyers are weighing how much to replace from other origins and at what cost. Shortfalls in Black Sea supplies have been a principal driver behind recent price gains, and physical markets in Argentina, Australia and the United States have reflected that upward pressure.
For now, regional harvests and government procurement in some countries have provided a buffer. But market participants say the combination of port closures, vessel attacks and shipowners' reluctance to call at the affected ports means that uncertainty over shipment arrivals is likely to persist through the near term.
That uncertainty carries implications for food processors, millers, shipping firms, and governments that rely heavily on imported wheat to meet domestic demand.
