Report Industry Investment Ratings No information provided in the given content. Core Views Oils and Fats - Palm oil: MPOB report shows inventory growth to 2.2 million tons, and the unexpected decline in the first 10 - day export data brings negative pressure. There is a risk of the futures price falling below 4,400 ringgit and continuing to weaken. Domestically, it will first consider the support at 9,000 yuan. If Malaysian palm oil weakens, Dalian palm oil may follow a downward - fluctuating trend [1]. - Soybean oil: Analysts expect the USDA report to lower the US soybean yield forecast, but the high - level of US soybean's excellent rate still maintains the expectation of a good harvest. The upcoming concentrated supply pressure will weigh on the market. Domestically, although the demand season is coming, the current oversupply of soybeans will keep the basis quotation in a narrow - range adjustment [1]. Meal Products - The high excellent rate of US soybeans suppresses the market's bullish sentiment. The strong supply and weak demand pattern of US soybeans continues. The relatively high Brazilian basis provides support for domestic costs. Recently, the domestic concern about future supply has eased, and the spot is loose. The increase in oil mills' soybean meal inventory and the lack of terminal purchasing enthusiasm suppress the basis. However, the cost support is strong, and the decline space of domestic meal products is limited [3]. Pig Industry - The slaughter of the breeding end is stabilizing, and the reluctance to sell at low prices has increased. The entry of secondary fattening in some areas provides support for the spot. The spot pressure has been gradually realized, and the price has fallen to a low - level range with limited further decline space. The demand is slowly recovering, but whether it can smoothly absorb the supply is uncertain. There may be a wave of concentrated slaughter before the double festivals. The market rebounded today due to the policy boost, but there is still potential for decline later, and the overall supply - demand pressure is large [6]. Corn Industry - In the Northeast, the purchase and sale are still dull, and the new season's corn has not been listed in large quantities, so the price remains firm. In North China, the supply is relatively sufficient, and the price continues to run weakly. As corn is transitioning to the new season, the tight inventory of old - season corn and the upcoming large - scale listing of new - season corn, along with the expected increase in production and the decrease in planting costs, put pressure on the price. On the demand side, the purchasing enthusiasm of deep - processing and feed enterprises is weak. In the short - term, the supply and demand of corn are both weak, and the futures price is under pressure, maintaining a weak pattern in the medium - term [8]. Sugar Industry - The sugar production in the central - southern region of Brazil in the first half of August increased year - on - year, and the sugar - making ratio reached a new high, resulting in a large supply pressure on raw sugar and a price drop below 16 cents per pound. The overall supply pressure of raw sugar remains large, and it is expected to maintain a weak pattern. However, as the sugar price approaches the tax - included ethanol price, the room for the future increase of the sugar - alcohol ratio in Brazil is limited. The new sugar will be on the market in less than a month, and the pre - sale price is lower than the current market price. The futures price is weak, and the market sentiment is weak. The sugar price is expected to fluctuate at the bottom [12]. Cotton Industry - Some cotton ginning factories have started purchasing this week, but the pricing methods of cotton for wadding and spinning are different, and the new cotton purchase driver is still unclear. In the short - term, the upward and downward space of domestic cotton prices may be limited, and the downstream has little confidence in the traditional peak season. In the short - term, domestic cotton prices may fluctuate within a range, and will be under pressure after the new cotton is listed [13]. Egg Industry - The increase in traders' purchases in recent days may drive up the egg price. However, the high inventory and the impact of cold - stored eggs on the market will suppress the increase of the egg price. After the second and third batches of replenishment in the second half of the week, the demand may fade, and the risk of the egg price decline increases. The egg price may rebound in early September, but the overall increase is limited, maintaining a bearish view [16].

Summary of Key Points from Conference Call Industry Overview - The conference call discusses the **government bond futures market** and its trading strategies, highlighting its role in risk management and investment opportunities [1][2][3]. Core Insights and Arguments - **Characteristics of Government Bond Futures**: - Features include short-selling mechanisms, margin trading, standardized contracts, and daily mark-to-market settlement, which help mitigate interest rate risks, lower transaction costs, enhance liquidity, and reduce credit risks [1][2]. - **Functions of Government Bond Futures**: - Key functions include hedging against interest rate fluctuations, price discovery, linkage between primary and secondary markets, and optimizing asset allocation [1][2][3]. - **Types of Government Bond Futures in China**: - China has introduced futures for 2-year, 5-year, 10-year, and 30-year government bonds, covering critical maturities. Each contract corresponds to different remaining maturity ranges, with longer maturities having wider price fluctuation limits and higher minimum margin requirements [1][4]. - **Basis and Net Basis**: - Basis is the difference between the cash bond price and the futures price adjusted for the conversion factor, serving as an important indicator for analyzing arbitrage opportunities. Net basis considers holding income, which is crucial for selecting the cheapest deliverable bond (CTD) [1][7][10]. - **Market Participants**: - Main participants in the government bond futures market include brokerage firms, asset management products (like public funds and private equity), individual investors, and some banks and insurance companies. The market has seen steady growth in trading volume and open interest since 2023 [5][6]. Additional Important Content - **Hedging Strategies**: - Hedging strategies include short and long hedges to manage interest rate risks. The process involves selecting contracts, calculating hedge ratios, dynamically adjusting positions, and managing rollovers [2][12][13]. - **Risks in Hedging**: - Risks faced during hedging include basis risk, financing spread volatility, and term mismatch risk. These risks arise from the imperfect correlation between the swap contract indicators and actual yields [17][27]. - **Interest Rate Swaps**: - Interest rate swaps are over-the-counter financial contracts that help manage interest rate risk by exchanging fixed and floating interest payments. They can also be used for speculation and cost reduction [21][22]. - **Arbitrage Opportunities**: - Arbitrage strategies in the futures market include directional trading and relative value strategies, such as term arbitrage and cross-asset strategies [19][28][29]. - **Risks in OTC Contracts**: - OTC contracts carry additional risks compared to exchange-traded contracts, including credit, operational, and valuation risks. Market risk arises if actual market conditions deviate from expectations [30]. This summary encapsulates the essential aspects of the government bond futures market and its associated trading strategies, highlighting both opportunities and risks for market participants.

Corn starch inventory has decreased this week, with the current inventory at 122.6 million tons, a decrease of 3.9 million tons from last week, a monthly decrease of 3.5%, and a year - on - year increase of 37.2% [8] - Price - influencing factors: Starch prices mainly depend on corn prices and downstream inventory. By - product prices are strong, and the spot price difference between corn and starch is low. With weak demand in the medium - to - long term, enterprises will be in a long - term loss state [8] Group 6: Trading Strategy - Unilateral: The US corn has support at 400 cents per bushel.
