Wheat surges as USDA projects lowest U.S. crop since 1970

Wheat futures on the Chicago Board of Trade CME Group Inc. ↗ 1.92% rallied sharply on Wednesday after the U.S. Department of Agriculture's August WASDE report projected U.S. wheat production at just 1.53 billion bushels for 2026 — down 23% from a year earlier and the lowest level since 1970.tradingkey

The report, released at noon Eastern on August 12, showed the national average yield falling to roughly 47.8 bushels per acre, compared with 53.3 bushels in 2025, a decline that reflects persistent drought conditions across key growing regions. The sharp supply cut came in well below trade expectations, triggering buying that pushed CBOT wheat futures up approximately 4%.admis+2

Black Sea Disruptions Amplify Supply Fears

The rally built on momentum that had already been lifting wheat prices ahead of the report. Disruptions to Black Sea shipping — sparked by intensified Russian and Ukrainian strikes on export infrastructure and commercial vessels — have been tightening global exportable supply for weeks.thestar+1

Turkey temporarily halted Black Sea transits for its vessels over the weekend amid heightened security risks, and Ukraine warned that its agricultural exports in the 2026-27 marketing year could fall by more than half compared with previous estimates due to Russian attacks. According to Reuters, a surge in attacks on ships, ports, and export terminals has been disrupting global supplies of grain and oil.reuters+1

Joe Davis, director of commodities at brokerage Futures International, told Bloomberg that while the disruptions don't necessarily translate into immediate additional U.S. export business, "they do tighten the global exportable supply outlook and balance sheets, forcing importers to diversify origins and keeping support under higher-quality wheat values".thestar

Export Demand Remains the Key Variable

The combination of a historically tight U.S. supply balance and elevated geopolitical risk in the Black Sea has made the wheat market increasingly sensitive to further weather disruptions or shipping delays. NDSU Extension Crops Economist Frayne Olson noted that if buyers who have ordered wheat from Ukraine or Russia face delayed shipments, "that causes a huge amount of problems for you as a buyer," and said continued disruptions could create additional export opportunities for U.S. wheat.rrfn+1

Still, analysts caution that a more sustained price rally would likely require a measurable improvement in overseas demand for U.S. wheat. The USDA's July report had already flagged tightening supplies, putting total U.S. wheat production at 1.536 billion bushels before August's further downward revision. With hard red winter wheat contracts seeing particularly sharp gains — given their direct competition with higher-protein Black Sea milling wheat — the market appears to be pricing in a world where U.S. exporters may need to fill gaps left by disrupted Black Sea flows.usda+2
