Corn Weekly Report

By: StoneX Intelligence Brazil, StoneX Intelligence Brazil

Strong crop in the US should continue dictating a downtrend in corn prices in Chicago

Market Intelligence Analyst
Domestic prices remain strong, generating doubts in the export market
  • Bearish factors
  • Large production in Brazil;
  • Favorable weather in the USA;
  • Indications of weaker domestic demand in the US.
  • Bullish factors
  • Heated consumption globally;
  • USDA estimates lower stocks for the 2025/26 crop at the global level;
  • Stronger exports in the US.

Weekly overview | Corn futures observed another week of decline. Last week, the December/25 contract traded in Chicago saw a drop of 1.3% to close at US¢405.50/bu, after testing resistance below the US¢400/bu level. At this point, the U.S. market sees little grounds for upside. The high levels of corn exports by the United States have little effect on the bearish dynamics that have been dominating trading in Chicago for several months now. The truth is that any reaction on the demand side will do little against the high production level expected for the U.S. crop. 

This week, the commodities market has reacted to statements by president Donald Trump that China could quadruple its purchases of soybean from the US. The fact is not based on any bilateral agreement and, in fact, seems implausible at the moment. In any case, the fact that Trump has taken the American agricultural sector into account in trade negotiations with China is already an important gesture, contributing to the bullish tone of the statement.

Exports | With three weeks left until the end of the corn crop year, U.S. corn exports are already almost in line with the current estimate by the USDA. In this way, the expectations are that the department will revise, in its monthly report to be published tomorrow, the country's shipment estimates upward. The export market was the highlight of this crop year, which saw the largest volume shipped by the USA in history. 

In addition to the robust North American crop, both last year and this year, factors such as more expensive corn from other sources, like Brazil and Ukraine, have made North American corn practically the unanimous choice among importers, such as Japan, South Korea, Spain, and especially Mexico, which has imported record volumes in recent months. 

From now on, the doubts weigh on whether Brazil can become competitive again after the progress of the safrinha corn harvest. The safrinha we see this year is robust and should sustain shipment levels above what was seen last year. Still, domestic prices have remained relatively high, a factor not helped by the Brazilian real, which has shown an appreciation dynamic versus the dollar since the beginning of the year, creating some uncertainty regarding the attractiveness of Brazilian corn in major destinations. 

US Crop | 73% of corn fields in the United States are rated in good/excellent condition. At this stage, the robust crop already leaves the realm of prospects and becomes an increasingly concrete reality. Most of the crops have already pollinated and are now entering the dough stage of the cornfields. 

In the coming weeks, the market will follow a series of field surveys that will collect productivity data in the main producing regions, which will provide clearer perspectives on productivity. Last week, we saw the results of the first crop estimate from the American division of StoneX, which indicated a yield of 11.81 tonnes/ha, which would constitute a record crop of 414.62 mmt for the United States. 

Some estimates indicate that the USDA may already revise American productivity in its estimate tomorrow. In any case, it is practically unanimous that the current estimate (the one from the July report) is below what will actually be realized after the harvest.

Brazil | Futures traded on B3 also declined last week. The expiration of November/25 ended the week trading at R$67.65/bag (-2.2%). Even though the movement may be related to seasonal pressure, it is worth noting that the depreciation of the real versus the dollar last week was practically of equal intensity (-2%). In this way, the contracts on B3 continue with substantial support, and the depreciation last week does not necessarily indicate a gain in competitiveness for Brazilian corn in international markets.

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.

Perspective: Morning Commentary for August 5

August 5 – U.S. equities markets are on fire this week, with both the Dow Jones and S&P 500 setting new all-time highs yesterday with futures indicating further gains again today; the marketplace remains optimistic over a deal with Iran despite no evidence of such as of yet. Crude oil is working on a lower high and low today but remains slightly on the high side on the session, while the dollar is retreating back towards Monday’s nearly two-month low. The ten-year note is steady-to-lower this morning (though solidly lower so far this month) at 4.605%, while the VIX index continues to rebound into mid-week at almost a 17-point reading this morning.

Perspective: Mid-Day Commentary for August 4

August 4 – The Dow Jones is absolutely piling on gains today, adding a similar number that led to yesterday’s record, with the benchmark index now nearing the 54k-point mark through mid-morning. The S&P also hit a new record, while the NASDAQ is exceeding both those gains on a percentage basis. The marketplace is optimistic on a U.S.-Iran trade deal, though the proposed resolution is still being “circulated between the parties”.
