Chicago Soybean Rally and Chinese Demand Lift Brazilian Prices
CBOT soybean futures surge on US weather fears and Chinese buying, driving Brazilian physical prices to R$ 141.00 per bag and boosting trading liquidity.

A sharp rally in Chicago Board of Trade (CBOT) soybean futures, fueled by escalating US Corn Belt drought fears and a resurgence in Chinese demand, has successfully revitalized physical pricing and trading liquidity across Brazil’s primary agricultural hubs. CBOT November soybean futures recently surged over 3% to around $11.81 per bushel, testing multi-week highs. This international momentum has quickly spilled over into South American cash markets, breaking a period of sluggish domestic trading.
In Brazil, physical soybean prices at the benchmark Paranaguá Port climbed to R$ 141.00 per 60-kilogram bag, up from R$ 137.50, effectively accelerating farmer selling after weeks of defensive holding by producers. The price recovery has injected much-needed liquidity into local markets, even as regional weather remains dry. Recent data highlights prolonged dry spells across key agricultural regions: Cascavel (PR) recorded just 1.2mm of rain over the last 7 days with 6 dry days; Luís Eduardo Magalhães (BA) saw 1.0mm and 7 dry days; Sorriso (MT) registered 2.1mm and 6 dry days; and Rio Verde (GO) remained entirely dry with 0.0mm of rain and 7 dry days.
The global demand picture has received a substantial boost from China. State-owned trading giant Cofco recently booked at least six US soybean vessels for September-October shipment, signaling a strong seasonal return to the market. This renewed appetite from the world’s top importer has shored up confidence for global trade flows, benefiting both US futures and Brazilian export premiums.
Market positioning reflects this shifting sentiment. According to the latest Commitment of Traders (COT) report, soybean speculative positioning stands at 215,618 long contracts versus 102,811 short contracts. Meanwhile, COT corn positions show 478,153 longs against 377,173 shorts, and coffee positions sit at 59,414 longs against 33,791 shorts. For financial markets tracking agricultural exchange-traded funds like SOYB, the Brazilian stock index (IBOV), and the USD/BRL exchange rate, the convergence of US weather premiums and robust Chinese buying continues to redefine the short-term outlook for agribusiness margins.
