Recently, global grain market prices have continued to decline due to a combination of ample supply and uncertainties. This week, multiple grain futures prices on the Chicago Board of Trade (CBOT) dropped, including soybeans, wheat, and corn. Soybeans continued to decline under the pressure of accelerated US harvests, and soybean meal and oil prices followed suit. Meanwhile, wheat prices hit a seven-week low due to improved weather conditions and expectations of high yields in the Southern Hemisphere. Corn prices further plummeted amid abundant global supply and a sluggish energy market.
Soybean Market Dynamics
As of October 28, Chicago soybean futures fell for the third consecutive trading day, with the most active soybean contract ZS1! at $9.81 per bushel, a decrease of 0.7%. With the rapid progress of the US soybean harvest, market supply pressure has increased. Although strong demand temporarily boosted prices last week, the ample supply clearly puts ongoing pressure on prices.
Market data shows that non-commercial traders, including hedge funds, have increased their net short positions on soybeans. This change in holdings reflects investors' pessimistic outlook on the future trend of soybeans. The rapid US harvesting is altering the market supply pattern, and prices may come under further pressure in the future.
Soybean Meal and Oil Market
Soybean meal and oil prices have also been dragged down by the soybean decline, with the overall market sentiment being cautious. As the supply of soybeans increases, the demand for soybean meal might face suppression, and even though some downstream demand remains strong, it has not effectively supported prices. Additionally, the soybean oil market is also weak, with increased supply expectations leading investors to adopt a wait-and-see attitude toward price trends, making a significant rebound unlikely in the short term.
Wheat Market Trend
Wheat futures fell by 1% on October 28, at $5.63-1/4 per bushel, a seven-week low. Improved recent rainfall in the US Plains has reduced the risk of planting delays, while expectations of abundant harvests in the Southern Hemisphere, particularly in Argentina and Australia, have pressured the market. Argentina's wheat exports for the 2024/25 season are expected to reach 13.3 million tons, the second-highest level in history. Despite adverse weather affecting parts of Australia, its overall production is still expected to be above average, collectively suppressing wheat prices.
Corn Market Analysis
As of October 28, Chicago corn futures ZC1! fell by 0.8%, at $4.12 per bushel, the lowest since October 22. The acceleration of the US harvesting process has strengthened market confidence in corn supply, and although some strong demand supports prices, the overall supply pressure cannot be ignored.
Positioning data shows that large speculators reduced their net short positions on CBOT corn futures in the week ending October 22, indicating a change in market sentiment. However, the weak performance of the energy market has added extra pressure to the corn market, keeping corn prices constrained.
Market Outlook and Risk Events
CBOT positioning changes and international bidding trends indicate cautious market sentiment. Although strong demand offers some support in the context of abundant supply, future price trends remain uncertain, especially with the US election approaching. There is widespread concern in the market about potential policy changes as a result of the election outcome, which could further influence grain futures prices.
Investors should closely monitor global economic dynamics, weather changes, and position reports from major exchanges to adjust strategies promptly.

In the current complex and volatile market environment, maintaining flexible and adaptive trading strategies is particularly important to cope with possible future price fluctuations and market risks.
