Report Information - Report Name: Nanhua Futures Corn & Starch Industry Daily Report - Date: October 15, 2025 - Analyst: Dai Hongxu (Investment Consulting License No.: Z0021819) - Research Assistant: Kang Quangui (Qualification Certificate No.: F03148699) - Investment Consulting Business Qualification: CSRC License [2011] No. 1290 Industry Investment Rating - Not provided in the report Core Viewpoints - The Dalian Commodity Exchange corn futures have declined rapidly in recent days, with the near - term November contract breaking below the 2,100 yuan mark. Based on the fourth - quarter forecast range, the price has taken an important step in bottom - finding. The price structure shows near - term weakness and long - term strength, corresponding to the decreasing pressure of spot supply. The 2601 contract is about to become the main contract, and the futures price regained 2,100 yuan yesterday. It may form a short - term consolidation and repair, and the opening of storage warehouses to purchase supports the rebound of the futures price. The registered warehouse receipts have slightly increased to 36,709 lots. [2] - In the spot market, the market continues to digest the pressure of new grain listing, and the spot price is weak. The purchase prices of deep - processing enterprises in Shandong and North China have more declines than increases. There are positive changes in the Heilongjiang production area, where some direct - affiliated warehouses of the China Grain Reserves Corporation have started to purchase corn, which stabilizes the price. With the start of purchases by the China Grain Reserves Corporation, the decline of the corn spot price may change rhythmically, and the recent large decline needs to be repaired. The positive factors in the market are accumulating, but during the period of new grain supply, the support is insufficient, and the market will mainly digest the pressure in the short term. By the end of this month, the new grain harvesting will enter the final stage, and important price nodes may appear. [2] - The CBOT corn futures price is running weakly, waiting for further guidance from the US Department of Agriculture's October supply - demand report. Due to the government shutdown, the report release time has been postponed.

Report Summary 1. Report Industry Investment Rating No information provided in the document. 2. Core Viewpoints of the Report - For corn, maintain a bearish outlook. The USDA's supply - demand report shows an increase in the estimated planting and harvest areas of US corn in the 2025/26 season, a decrease in the estimated yield per acre, and an overall increase in production, which is higher than analysts' average expectations. In the domestic market, although low trade - grain inventories support prices, factors such as imported corn auctions, wheat for feed, approaching new - corn harvest seasons in North and Northeast China, and weak downstream demand lead to a decline in purchase prices. However, the slightly higher opening prices of new - season corn in some areas support market sentiment. [8][9][10] - For corn starch, also maintain a bearish outlook. The raw - material corn is in a new - old alternation period. Some enterprises have new maintenance due to insufficient raw - material supply, and the industry's operating rate is low. Although demand has slightly improved and inventory pressure has declined, the overall inventory is still high, and the substitution advantages of cassava starch and wheat starch squeeze the market demand for corn starch. [13][14] 3. Summary According to the Catalog 3.1 Weekly Highlights Summary - **Corn**: The closing price of the main 2511 contract was 2168 yuan/ton, a decrease of 29 yuan/ton from the previous week. The USDA's report shows an increase in US corn production. Domestically, new - corn harvest is approaching, and downstream demand is weak, but the slightly higher opening prices of new - season corn support sentiment. [10] - **Corn Starch**: The closing price of the main 2511 contract was 2463 yuan/ton, a decrease of 11 yuan/ton from the previous week. The raw - material supply is in an alternation period, the operating rate is low, demand has slightly improved, and inventory has decreased, but it is still high, and substitution products squeeze the market. [14] - **Strategy Suggestion**: Maintain a bearish outlook for both corn and corn starch. [9][13] 3.2 Futures and Spot Market Conditions - **Futures Price and Position Changes**: The 11 - month contract of corn futures closed lower with a total position of 811,835 lots, a decrease of 39,928 lots from the previous week.

China has imposed a 15% tariff on US corn, with a total of 26% tariff within the quota, and a 22% tariff on US sorghum. The import profit of foreign corn is relatively high, with the December Brazilian import price at 2116 yuan. The northern port closing price is stable at around 2310 yuan, and the spot price in the northeast corn - producing area is relatively strong. The supply in North China has increased, leading to a decline in the spot price, and the price difference between northeast and North China corn has narrowed. The wheat price in North China is weak, and the price difference between wheat and corn is small, so wheat continues to be a substitute. The domestic breeding demand is still weak, and the inventory of downstream feed enterprises is high. The corn spot price is relatively stable in the short term. Due to recent imports and domestic corn auctions, and the upcoming large - scale listing of new - season corn, the corn spot price is expected to decline. It is estimated that by the end of September, the North China corn price may reach 2200 yuan/ton, and the price in Heilongjiang may be below 2100 yuan/ton [5][7] Starch - The number of vehicles arriving at Shandong deep - processing plants has increased, and the Shandong corn spot price is stable. The starch price in Shandong is around 2750 yuan, and the northeast starch spot price is also weak. This week, the corn starch inventory has decreased to 122.6 million tons, a decrease of 3.9 million tons from last week, a monthly decrease of 6.98% and a year - on - year increase of 40.3%. The current starch price mainly depends on the corn price and downstream inventory - building. The average income from by - products in the past few years has been over 600 yuan, and today the by - product contribution in Shandong is 630 yuan (670 yuan in Heilongjiang). The by - product price is still strong, much higher than last year, and the spot price difference between corn and starch is low. The North China corn price is stable in the short term, while the northeast corn price is relatively weak. In the medium and long term, due to weak starch demand, enterprises will be in a long - term loss state. Today, the 01 starch contract has followed the corn price in a weak shock. The North China corn price still has room to fall by early October, and the corn starch spot price will also decline later. The loss of North China deep - processing plants will expand, and it is expected that the 01 starch contract on the short - term disk will continue to be in a weak shock [8] Group 4: Trading Strategies - For the US corn, there is support at 400 cents per bushel. It is recommended to mainly wait and see for the 01 corn contract. For arbitrage, it is recommended to wait and see [10][11] Group 5: Corn Option Strategies - Spot - holding enterprises can close out their short positions in corn call options, or they can try to gradually sell at high prices in the short term and conduct rolling operations [14] Group 6: Related Attachments - The report includes six figures, namely the spot price of corn in various regions, the basis of the corn 01 contract, the 1 - 5 spread of corn, the 1 - 5 spread of corn starch, the basis of the corn starch 01 contract, and the spread of the corn starch 01 contract [16][17][21]
