Argentina's Wheat Output to Fall 23% as Black Sea War Disruptions Tighten Global Supply

The global wheat market is entering a fresh phase of uncertainty as two major supply-side developments threaten to tighten international availability. Argentina, one of the world's largest wheat exporters, is expected to produce significantly less wheat in the 2026-27 marketing year, while the ongoing Russia-Ukraine conflict continues to disrupt grain exports from the strategically important Black Sea region.

The combined impact of a smaller South American crop and severe logistical disruptions in the Black Sea is forcing importing countries to seek alternative suppliers, increasing competition for available wheat and supporting higher international prices. The US Department of Agriculture (USDA) has already projected that US wheat production this year could be the lowest since 1970.

According to the US Department of Agriculture's Foreign Agricultural Service (FAS), Argentina's wheat production for the 2026-27 season is now projected at 21.6 million tonnes, around 23% lower than last year's record harvest. Although the estimate has been revised upward by 600,000 tonnes from the agency's April forecast due to higher planted area and favourable late-season weather, output will still be 6.3 million tonnes below the previous season because last year's exceptional yields are unlikely to be repeated.

The harvested wheat area has been revised to 6.6 million hectares, reflecting an additional 200,000 hectares brought under cultivation as lower input costs encouraged farmers to expand planting. More than 90% of the crop had been planted by mid-July.

Despite lower production, Argentina's wheat exports are expected to remain substantial at 15.5 million tonnes, although they will be well below the record export volumes associated with last year's bumper crop. Domestic wheat consumption is projected to rise to 7.65 million tonnes, partly because abundant stocks of lower-quality wheat are expected to be diverted to livestock feed.

At the same time, the Russia-Ukraine war has emerged as an even greater concern for global grain trade. Escalating attacks on grain terminals, port infrastructure and cargo vessels have sharply reduced export capacity from both countries, which together account for a significant share of global wheat exports.

Ukraine's grain export capacity through the Black Sea has reportedly fallen by about one-third following repeated missile and drone attacks on port infrastructure. Meanwhile, Russian grain exports have also been affected as attacks on shipping routes and facilities in the Sea of Azov have disrupted logistics.

The worsening security situation has discouraged commercial shipping in the region, with insurers charging higher premiums and freight costs rising significantly. Several merchant vessels have been damaged in recent months, making grain shipments increasingly risky and expensive.

The disruption has effectively trapped large quantities of wheat within Russia, where alternative transport routes lack sufficient capacity to replace Black Sea export channels. Even though Russia is forecast to harvest 88.5 million tonnes of wheat and export around 47 million tonnes during the 2026-27 marketing year, moving that grain efficiently to international buyers has become increasingly difficult.

With Black Sea supplies constrained, importing nations are turning to exporters such as the European Union, Canada, the United States and Kazakhstan. However, global supply flexibility is also limited as Australia is expected to harvest a smaller crop, the European Union is coming off an exceptionally strong previous season, and the United States is projected to record its smallest hard red winter wheat harvest in decades.

The tightening supply outlook has already been reflected in international markets, with wheat futures climbing to their highest levels since 2024 during July. Market participants expect continued volatility as geopolitical risks, weather uncertainties and shifting trade flows reshape global wheat availability over the coming months.
