Report Investment Rating - No investment rating information provided Core Views - For corn, with the U.S. corn harvest advancing, supply pressure will gradually increase, but the expected lower U.S. corn yield and the Sino - U.S. trade agreement expectation support the market. In China, the new corn supply is increasing, leading to a slight decline in purchase prices. Corn futures prices are in a low - level consolidation [2]. - For corn starch, the increasing supply of raw corn weakens cost support, and the substitution of tapioca starch squeezes market demand. However, the lower - than - usual industry operation rate, good order fulfillment, and slightly decreased inventory are positive factors. Starch futures prices move in sync with the corn market and are recommended for short - term observation [2][3]. Section Summaries Futures Market - Corn futures closing price (active contract) is 2116 yuan/ton, down 105 yuan/ton; corn starch futures closing price (active contract) is 2427 yuan/ton, down 11 yuan/ton.

Group 1: Report Overview - The report is the South China Futures Corn & Starch Industry Daily, dated October 29, 2025, written by Dai Hongxu and research assistant Kang Quangui [1] Group 2: Core Views - The national autumn grain harvest in major producing areas is over 85%. The corn market harvest is nearing completion, but selling pressure remains high, pressuring prices. Futures prices are in a post - bottoming - out and retracement phase, while spot prices are in a post - stop - falling and stabilizing and fluctuating process [2] - On Tuesday, the corn futures market showed a narrow - range and slightly upward trend, supported by the rise in the outer market and the strength of soybeans. The main 01 contract rose 0.28% to close at 2123 yuan, with decreased trading volume and a slight increase in open interest. The corn starch futures market was weak, with the main 01 contract closing at 2424 yuan [2] Group 3: Market Influencing Factors Bullish Factors - State reserve purchase points in the Northeast region are supporting prices, limiting downward movement [6] - The shortage of high - quality corn in North China will become more apparent over time, supporting the expectation of stronger long - term prices [6] - After the peak of harvest and selling pressure, it will become more dispersed, and price pressure is expected to gradually ease [6] Bearish Factors - The pig industry is in the process of capacity regulation, which may affect long - term corn feed demand. However, the high inventory in the fourth quarter and the current entry of second - fattening pigs support the feed demand at a relatively good level [3] - Short - term supply pressure remains high, and prices are consolidating at a low level [3] Group 4: Price Forecast - The monthly price forecast for corn is in the range of 2050 - 2200 yuan, with a current volatility of 8.75% and a volatility percentile of 23.6%.

1. Report Industry Investment Rating - No relevant content provided 2. Core Views - The U.S. government shutdown has led to the non - release of the crop progress report by the U.S. Department of Agriculture, causing cautious market trading. As the U.S. corn harvest progresses, supply pressure will gradually increase, putting downward pressure on U.S. corn prices. However, the estimated lower corn yield in the U.S. this year than the previous USDA forecast provides some support for prices [3]. - In the domestic Northeast region, the accelerated harvest of new - season corn, the purchase of new grain by multiple Sinograin direct - affiliated warehouses, and the improvement of corn storage conditions have led to a slowdown in the shipment of some growers. Although deep - processing enterprises have raised quotes, the pressure of concentrated supply of new - season corn still exists, and prices fluctuate slightly. In the North China and Huanghuai regions, the remaining grain in the market is scarce, and the market supply is increasing rapidly, causing the purchase price to fluctuate weakly [3]. - For corn starch, the increasing supply of new - season corn reduces cost support, and the substitution advantage of tapioca starch squeezes market demand. However, the industry's operating rate is lower than the same period in previous years, the supply - side pressure is not large, and enterprise inventories have slightly declined. The corn starch market is generally in a bearish trend [3]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - As the U.S. corn harvest progresses, supply pressure will gradually increase, putting continued downward pressure on U.S. corn prices. In the domestic market, the supply pressure of raw corn increases with the gradual increase in the listing volume of new - season corn, leading to a weakening of the overall price. The cost support for corn starch declines accordingly. The downstream demand for corn starch is also affected by factors such as industry shutdowns during holidays, high inventory, and substitution by other starches, resulting in a bearish outlook for the starch market.

1. Report Industry Investment Rating - No information provided 2. Core Views - For corn, the USDA report predicts that the US corn production in the 2025/26 season will reach a record - high of 16.814 billion bushels, and the ending stocks will also reach the highest level in seven years. With the progress of US corn harvest, the supply pressure will gradually increase. However, the early harvest results are mixed, leading to an expectation of a possible downward adjustment in US corn production. In the domestic market, the new grain harvest area in Liaoning and Heilongjiang in the Northeast region is expanding, and farmers' enthusiasm for selling grain is high. As the supply of new corn increases, the downstream demand is relatively weak, the losses of deep - processing enterprises are intensifying, and the purchase price has been lowered. The new - season corn listing still restricts the futures market [2]. - For corn starch, the market is currently weak, and enterprises are still in a loss state. The industry's operating rate is generally low. Due to a slight improvement in pre - holiday demand, the inventory continues to decline. As of September 24, the total starch inventory of national corn starch enterprises was 1.139 million tons, a weekly decrease of 61,000 tons, a weekly decline of 5.08%, a monthly decline of 13.58%, and a year - on - year increase of 28.85%. However, the industry inventory is still high, and the substitution advantages of tapioca starch and wheat starch are still significant, squeezing the market demand for corn starch. Although there has been a slight rebound at low levels recently, the demand support is insufficient, and the corn starch market maintains a bearish outlook [3]. 3. Summary by Relevant Catalogs 3.1 Futures Market - Corn futures: The closing price of the active contract of corn starch futures was 2,469 yuan/ton, up 22 yuan; the closing price of the active contract of CBOT corn was 425.75 cents/bushel, up 4 cents. The net long non - commercial position of CBOT corn decreased by 36,169 contracts, and the total position increased by 51,949 contracts [2]. - Corn starch futures: The closing price of the active contract was 2,164 yuan/ton, up 6 yuan.
