Top developments
CBOT Futures Retreat After Multi-Year Highs
On Friday, September 4, Chicago Board of Trade (CBOT) futures closed lower, with wheat posting the largest decline among the major grains. The pullback was attributed to profit-taking after corn and wheat had recently touched three-year highs, combined with a lack of new bullish catalysts ahead of the US Labor Day holiday on Monday, September 7. This correction suggests that while the fundamental supply tightness remains, traders are cautious about chasing prices higher without fresh USDA data or export surprises.

Brazil Sees Surge in Soybean and Corn Sales
Brazilian farmers are accelerating the sale of their 2025/26 soybean and corn crops as international prices remain robust. Reports indicate that nearly 3.4 million tons of soybeans and related products were registered for export in early September alone, reflecting a significant acceleration compared to previous weeks. This surge is supported by high global demand and competitive pricing, which has also boosted Argentine farmers' willingness to sell, with local markets seeing some of the highest prices in three years.

Black Sea Export Disruptions Impact Global Wheat Flows
Russian wheat exports through Black Sea ports have dropped to their lowest level for August in 16 years, according to analysts at SovEcon. The decline is driven by drone attacks on port infrastructure and increased insurance costs, which have significantly raised the risk premium for shipping from the region. Consequently, French wheat has gained competitiveness in North African markets as buyers seek more reliable supply routes, potentially tightening global wheat balances in the near term.

Local view
In Argentina, local media reports that the improvement in international grain prices has translated directly into higher farm-gate values, encouraging producers to liquidate inventory despite historical tendencies to hold back. El Cronista notes that this acceleration in sales is providing a significant influx of foreign currency to the Argentine economy, with projections suggesting agro-export revenues could exceed $13 billion by year-end. Meanwhile, in Brazil, Globo Rural highlights that the start of the 2026/27 soybean planting season in Paraná state is proceeding normally, with early planting efforts underway amidst stable exchange rates.
Context & numbers
The USDA's September WASDE report is scheduled for release on September 11, 2026, which will be a critical driver for future price direction as it updates yield estimates for the US corn and soybean harvests. Recent flash sales announced by the USDA in late August indicated continued strong demand for US corn and soybeans in the new marketing year, which officially began on September 1. Hedgepoint Global Markets projects Brazil's 2026/27 soybean crop at 181.7 million tons, emphasizing that domestic consumption and exports will sustain prices in the second half of the year.
On the radar
- USDA WASDE Report: The September supply and demand report is due on September 11, offering the first major update on US crop conditions post-harvest.
- Black Sea Security: Continued monitoring of drone attacks on Russian ports and any potential EU responses to grain transit issues via Latvia.
- Brazilian Planting Progress: Watch for AgRural and other agencies' weekly reports on the pace of the 2026/27 soybean planting in Brazil, particularly in Paraná and Mato Grosso.
