Brazilian Soy Prices Jump R$ 3 on Chicago Rally and US Weather
A 4% surge in CBOT soy futures driven by dry US weather forecasts has boosted physical trading prices at Brazilian ports, prompting local farmers to lock in sales.
A sharp rally in international agricultural commodities has immediately transmitted to the Brazilian physical market. On July 6, 2026, Chicago Board of Trade (CBOT) soybean futures surged over 4%, with the benchmark November contract reaching $11.92 per bushel. The rally was fueled by dry, hot weather forecasts threatening yield potential across the US Corn Belt, alongside expectations of renewed Chinese import demand.
This international spike triggered a swift reaction in Brazil's physical grain market, where domestic soy prices jumped by up to R$ 3.00 per 60-kilogram bag. At the key port of Paranaguá, prices rose to R$ 139.00, while Rio Grande physical prices hit R$ 140.00. The sudden premium expansion prompted a wave of forward-selling, as local farmers capitalized on the price spike to lock in margins for the upcoming crop.
The rally comes amid prolonged dry conditions in key Brazilian agricultural regions. Real-time weather data for July 7, 2026, shows 0.0 mm of rainfall over the last seven days in Sorriso (Mato Grosso) and Luís Eduardo Magalhães (Bahia), with both hubs recording 7 consecutive dry days. Rio Verde (Goiás) registered a mere 0.6 mm of rain over the same period, while Cascavel (Paraná) received 17.4 mm. In financial markets, the USD/BRL closed at R$ 5.13, while the latest CFTC Commitment of Traders (COT) data shows soybean speculative positioning at 197,868 long contracts versus 121,241 short contracts.
