Corn futures edge higher as export demand and supply concerns offset steady close
September and December contracts climb 2 to 3 cents following a USDA export sale to Mexico, while traders await the August Crop Production report.
Corn futures advanced by 2 to 3 cents in early Monday trading, building on a steady to fractionally higher close from Friday. The uptick in prices comes as market participants digest new export data and position themselves ahead of critical supply reports later this week.
The CmdtyView national average Cash Corn price remained unchanged at $4.09 1/2. Meanwhile, specific contract prices showed modest gains, with September 2026 corn closing at $4.39 and December 2026 corn at $4.62, both currently trading up 2 3/4 cents. March 2027 corn closed at $4.77 3/4, up a quarter of a cent, and is also trading 2 3/4 cents higher.
A key driver of the early momentum was a private export sale reported by the USDA on Friday. The sale involves 286,097 metric tonnes of corn destined for Mexico, comprising 29,808 tonnes for the 2026/27 season and 256,289 tonnes for the 2027/28 season. This demand signal provided support for futures prices in the absence of broader directional volatility.
Market sentiment is also being influenced by global supply conditions, particularly in South America. According to AgRural, Brazil’s second crop harvest reached 79% in the centre south region. This pace lags significantly behind the 88% recorded at the same time last year, raising questions about the speed of availability in key export markets.
Institutional positioning has shifted slightly, with CFTC data showing managed money added 13,547 contracts to their net long position in corn futures and options for the week ending 8 August. This brought the total net long exposure to 181,946 contracts as of Tuesday. Investors are now looking ahead to the upcoming August Crop Production report from the National Agricultural Statistics Service (NASS), scheduled for release next Wednesday.
A Reuters survey of analysts anticipates the NASS report will show a yield of 182.4 bushels per acre, with a projected range between 180.5 and 184.8 bushels per acre. Total production is estimated at 15.934 billion bushels, as harvested acres are expected to be trimmed by 76,000 acres.
