  • Strong global consumption;
  • USDA projects lower stock levels globally for the 2025/26 season;
  • Strengthened US exports;
  • Improved US-China relations.
  • Bearish factors

  • Higher stock levels in the US.

CBOT

The week saw gains for corn traded in Chicago. The December/25 contract closed Friday at US¢422.50/bu (+0.2%).

Market optimism is driven by the easing of trade tensions between the US and China. Significant anticipation surrounded Sunday’s (26) meeting between US Treasury Secretary Scott Bessent, US Trade Representative Jamieson Greer, and Chinese Vice Premier He Lifeng. Throughout the week, signs pointed to a productive meeting, which was confirmed yesterday when Bessent revealed discussions about the framework of a trade agreement between the two nations. The agreement could potentially include a commitment not to limit exports of rare earth metals.

The Secretary also stated that China has pledged to purchase “substantial” volumes of US soybeans. This announcement was highly anticipated by the US grain market, and soybeans have already risen by approximately 2% in early Monday trading as a result.

All indications suggest a temporary resolution of trade conflicts, providing some relief to the market. Attention now turns to the upcoming meeting between Donald Trump and Xi Jinping on Thursday, as well as the progression of trade agreement negotiations following the meeting.

During his Asia trip, Trump is currently in Japan, where new trade agreements are being discussed. Newly appointed Japanese Prime Minister Sanae Takaichi has hinted that the country may expand its soybean imports from the US. However, Japan’s import potential extends beyond soybeans, including increased purchases of corn and rice.

On the fundamentals side, the US harvest continues. However, due to the US government shutdown, market updates on harvest progress remain limited. Additionally, ethanol production has increased in the US in recent weeks, boosting optimism regarding corn consumption this season and strengthening futures prices in Chicago.

On the fundamentals side, the US harvest continues. However, without major updates due to the government shutdown, the market sees few changes in harvest outlooks.

Regarding demand, despite the lack of export data, the market anticipates robust corn shipment flows, although concerns about drought conditions along the Mississippi River remain in focus.

Moreover, ethanol production has been increasing in the US in recent weeks, further supporting optimism about corn consumption this season and reinforcing futures prices in Chicago.

Brazil

Corn prices on B3 saw a sharp decline last week, with the November/25 contract closing at BRL 67.20/lb (-1.9%). Recent weeks have shown relatively stable market fundamentals, with price movements largely driven by technical market factors and currency fluctuations, as will be explored further ahead.

Regarding summer crops, there’s little new to report. Planting is generally progressing well for both soybeans and summer corn, increasing optimism around Brazil’s production for 2026. October exports have also been advancing at a healthy pace, with shipments totaling 3.6 million tonnes in the first half of the month. This points to October potentially surpassing the 4.7 million tonnes of corn exported in October 2024.

Exchange rate

Last week, the foreign exchange market responded to inflation data from the US and Brazil, both of which came in below market expectations. In the US, weaker CPI data paves the way for further interest rate cuts, likely to occur during the next two FOMC meetings before year-end. In Brazil, although controlled inflation also supports the case for rate cuts, monetary authorities have emphasized that inflation remains above target, suggesting a more conservative approach by COPOM until prices stabilize further.

As a result, the widening interest rate differential is expected to continue strengthening the Brazilian real in the coming months.

Additionally, President Lula met with Donald Trump in Malaysia on Sunday (26). The meeting appears to have been positive, with Brazilian and US officials likely to continue negotiating a trade agreement, which would further support the real.

  • Special | Argentina

  • Argentina is projected to plant 7.8 million hectares of corn in the 2025/26 season, a 700,000-hectare increase compared to 2024/25. Assuming similar productivity levels to last year’s crop, this expansion could deliver a production of approximately 54 million tonnes next year. So far, planting has reached 33.8% of the total area, a notably faster pace compared to last year, when only 28.9% of the crop had been planted during the same reference week.

    While accelerated planting strengthens the outlook for a robust crop in Argentina, producers remain cautious about the potential impact of La Niña this year, which typically brings drier weather to Argentine fields and may affect productivity.

    In the short term, however, a weather system forming in the southern region of the continent is expected to bring more unstable conditions to fields in Buenos Aires province, followed by cooler temperatures, which could impact crop development.

    If Argentina achieves a strong crop, it could become a key supplier to meet Brazil’s corn demand in the first half of next year, especially if domestic consumption continues to grow.

Perspective: Morning Commentary for August 7

August 7 – The U.S. economy unexpectedly lost 23k jobs in July, dramatically below market expectations of an 80k increase and marking the worst Non-Farm Payrolls print since February. Furthermore, May and June were both revised sharply downward, with combined revisions showing 103k fewer jobs than previously reported. Outside of the healthcare sector, which added 22k jobs in July, the losses were very broad-based. Government payrolls saw the largest decline, shedding 53k jobs in July, the largest seen since October 2025, while June was revised down to show a loss of 10k jobs as well. The private sector at least saw growth, adding 30k jobs in July, now matching the month prior after it was revised down from the 49k initially reported, and substantially missing forecasts of 78k jobs being added. This is a sharp reversal in course from the largely better than expected U.S. labor data seen earlier this week.

Perspective: Mid-Day Commentary for August 6

August 6 – Stocks remain quietly mixed at midday as both the S&P 500 and Dow Jones remain just below their fresh all-time highs put in yesterday. This is allowing the VIX to cool to a four-week low below the 15.4 mark, reflecting the collective sigh of relief in the market amid largely better than expected U.S. economic data today. The dollar remains quietly in the green in its relatively tight range this week, trading at 99.9 at the time of writing. Treasuries remain elevated but have cooled from their recent peaks, with 30-year yields trading at 5.189%, 10-year yields trading at 4.647%, and 2-year yields trading at 4.229% at midday. Crude oil also remains quietly in the green, with nearby WTI up 2.3% on the day trading near $76.80 and nearby Brent up 2.4% on the day trading near $81.40. The ags remain mixed, with the wheat complex now squarely in the red while corn and soybeans cling to small gains, and the livestock complex largely pushes lower.

Perspective: Morning Commentary for August 6

August 6 – This morning’s stronger-than-expected U.S. labor data offered markets some relief, reinforcing confidence in the economy while giving the Fed greater flexibility to raise rates should inflationary pressures reaccelerate in next week’s July data. Stock futures are pointing to a mixed open to start the day, with the tech-heavy Nasdaq showing the most weakness. The VIX has fallen notably from yesterday’s spike above 18.4 as it starts the day hovering just below the 16-mark. The dollar is quietly higher as it trades just above 99.8, holding in the tight range seen thus far this week as traders continue to digest data to shape expectations for the Fed’s next move, which we’ll dive into in more depth below. Long-term treasury yields have relaxed slightly from their recent spike, with 30-year yields starting the day trading just above 5.19%, while 10-year yields trade above 4.64%, and 2-year yields sit below 4.22%. Crude oil is modestly higher to start the session after sharp declines earlier in the week, with nearby WTI up 1.8% to trade at $76.40 and nearby Brent up 2.4% to trade at $81.40. Meanwhile, the ags are quietly mixed to start the day.
