1. Report Industry Investment Rating - The investment rating is "Oscillating and Bullish" [1] 2. Core View of the Report - The short - term steel price is mainly oscillating and bullish. The fundamentals are currently supported by supply contraction and inventory reduction, giving it the impetus to rebound, but weak demand restricts the upside. In the medium term, it is necessary to focus on the demand recovery. If demand continues to pick up, steel prices are expected to start a trend - based rebound; if demand remains weak, steel prices will maintain an oscillating pattern [6] 3. Summary by Relevant Catalogs Market行情回顾 - Futures price: The open interest of the main rebar contract decreased by 99,718 lots on Monday. The trading volume increased compared to the previous trading day, reaching 616,727 lots.

Production has been continuously declining, and the year - on - year decline is significant. Steel mills are actively reducing production [3] - Demand side: In the week of March 26, 2026, the current apparent demand was 2.2537 million tons, a week - on - week increase of 172,800 tons and a year - on - year decrease of 199,600 tons. The weekly demand has recovered month - on - month, but it is still weak year - on - year, and the demand repair is insufficient [3] - Inventory side: Social inventory was 6.4275 million tons, a week - on - week decrease of 104,600 tons. Social inventory has been continuously decreasing, but it is still higher than in previous years. The enthusiasm of end - users for purchasing is average. Steel mill inventory was 2.1916 million tons, a week - on - week decrease of 170,400 tons. The steel mill inventory decreased on a weekly basis, and it is slightly higher year - on - year. The inventory pressure of steel mills has been marginally relieved. The total inventory was 8.6191 million tons, a week - on - week decrease of 275,000 tons. The total inventory decreased on a weekly basis, but there is still about a 5% inventory build - up year - on - year, and the inventory pressure remains [3] - Cost and profit: The steel price valuation is at a low level. Geopolitical factors have pushed up oil prices and shipping costs, providing support for commodity prices [4] - Macroeconomic aspect: The Fourth Session of the 14th National People's Congress held on March 5, 2026, sent positive signals. The government work report proposed measures such as "issuing ultra - long - term special treasury bonds worth 1.3 trillion yuan", "arranging local government special bonds worth 4.4 trillion yuan", and "implementing a moderately loose monetary policy" to stabilize growth. The market's expectation of infrastructure and real estate support has increased, and the sentiment has received phased support [4] Driving Factor Analysis - Bullish factors: Steel mills are actively reducing production, the supply side has significantly contracted, inventory has been continuously decreasing, the inventory - to - sales ratio has improved, and steel prices have bottom support [5] - Bearish factors: The end - user demand is weak year - on - year, the recovery is less than expected, the total inventory is still increasing year - on - year, and traders lack confidence, which restricts the upside of steel prices [5] Short - term View Summary - The main rebar contract is accelerating the shift of positions, and it is estimated that the position shift will be completed in the near future. The outlook remains optimistically bullish. The lower support for the 05 contract is near the 30 - day and 60 - day moving averages. In the short term, the fundamentals are supported by supply contraction and inventory reduction, giving it the impetus to rebound, but weak demand restricts the upside [6]

1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoint of the Report - The iron ore market is expected to show an oscillating trend. The short - term trend depends on the spot liquidity issues of some varieties and the development of the US - Iran conflict, with increased volatility recently. The overall fundamentals are weak, but due to geopolitical disturbances, it is difficult to trade based on fundamental logic. With a positive basis and a continued BACK structure, the downside space is limited, and it will continue the high - level oscillating rhythm [2][5] 3. Summary by Relevant Catalogs Market行情态势回顾 - Futures price: The main contract of iron ore futures oscillated during the day, closing at 813 yuan/ton, up 1 yuan/ton or 0.12% from the previous trading day's closing price. The trading volume was 143,000 lots, the open interest was 371,000 lots, and the settled funds were 6.643 billion yuan. It is currently oscillating between the short - term support near 800 and the short - term resistance near 830 [1] - Spot price: The mainstream spot varieties at Qingdao Port, PB powder, rose 4 to 790, and Super Special powder rose 4 to 672. The main swap was at 107.2 (- 0.05) US dollars/ton. The swap was oscillating at a high level, and the spot prices rose slightly [1] - Basis and spread: The converted futures price of PB powder at Qingdao Port was 824.7 yuan/ton, with a basis of 11.7 yuan/ton, and the basis slightly shrank. The 5 - 9 spread of iron ore was 22 yuan, and the 9 - 1 spread was 19.5 yuan [1] Fundamental Analysis - The US - Iran conflict disrupts the shipping and arrival rhythm of overseas mines, and the Australian hurricane still affects shipping. High oil prices push up the shipping cost of iron ore, and the liquidity of some spot varieties is restricted, making it difficult to trade the overall supply - demand relaxation pressure of iron ore. The short - term trend depends on the spot liquidity issues of some varieties and the development of the US - Iran conflict, and the recent volatility may increase [2] Macro - level Analysis - Domestic: Policy support continues, profit improvement is evident, and physical work volume shows a structural improvement. From January to February, the profits of industrial enterprises increased by 15.2% year - on - year, the profits of the manufacturing industry increased by 18.9% year - on - year, and the profits of high - tech manufacturing increased by 58.7% year - on - year. Real estate transactions have marginally recovered, but land transactions and the listing prices in first - tier cities are still weak. The issuance progress of special bonds is relatively fast, but the elasticity of infrastructure physical work volume may be lower than the nominal scale. Overall, the domestic macro situation is in a state of "continued policy support, marginal profit improvement, and slow demand recovery" [4] - Overseas: The US economy has not stalled, but the combination of "weak demand + high oil price risk" still limits the short - term turning space of the Federal Reserve. The overseas macro environment presents a pattern of "no stall in growth, persistent inflation disturbances, and limited policy space" [4] Viewpoint Summary - On the iron ore fundamentals, the supply side remains loose, the molten iron output on the demand side still has room for further recovery. Attention should be paid to the support strength of peak - season demand. Port inventories have declined to some extent and shifted downstream. The overall fundamentals are still weak. Due to geopolitical disturbances, it is difficult to trade based on fundamental logic. With a positive basis and a continued BACK structure, the downside space is limited, and it will continue the high - level oscillating rhythm [5]

Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - This weekend, the national pig price showed a weak and volatile trend. The north continued to be weak due to supply pressure, while the south showed a mixed trend of stability and decline supported by regional price differences. As the Minor New Year approaches, terminal stocking has limited support for prices, and the market pattern of strong supply and weak demand remains unchanged. In the short term, the resistance sentiment of the breeding side and the price - pressing mentality of slaughtering enterprises will continue to compete. The pig price in the north may adjust slightly, and the decline in the south may narrow due to active external sales, but overall, there is a lack of rebound momentum. It is expected that the pig price will remain weak before the Spring Festival [2] 3.

Part II: Market Analysis - **Corn**: The drought in Argentina has led to a bottom - rebound of U.S. corn, but it is still oscillating at the bottom due to global supply pressure. The import profit of foreign corn is rising. The northern port's flat - hatch price has declined, while the spot price in the Northeast corn - producing area is stable. The supply of corn in North China has decreased, and the spot price is strong. The price difference between Northeast and North China corn has narrowed. Wheat and corn are still being auctioned.

Farmers' reluctance to sell has weakened, and the port inventory is low. The purchase price at northern ports is weak today. The price of the March contract has continued to decline, and the basis of the spot price has strengthened [4][6]. - **Corn Starch**: The number of trucks arriving at Shandong deep - processing plants has increased, and the spot price of corn in Shandong is stable. The spot price of corn starch in Shandong is around 2770 yuan, and that in the Northeast is stable. The inventory of corn starch has decreased this week, with the manufacturer's inventory at 102.8 million tons, a decrease of 4.1 million tons from last week, a monthly decline of 6.7%, and a year - on - year decline of 8.0%.

1. Report's Industry Investment Rating - Not provided in the report 2. Core Viewpoints of the Report - The US corn report significantly increased the production forecast, leading to a sharp decline in US corn prices. However, the global corn supply pressure has weakened, limiting the downside space for US corn prices. The import profit of foreign corn is rising, and the import price from Brazil in February is 2126 yuan.

The import profit of foreign corn is rising, and the domestic northern port closing prices are rising. The northeast corn spot is strong, while the supply in North China is increasing, and the corn price is stable. The price difference between northeast and North China corn is narrowing. Wheat and corn are being auctioned, and wheat prices are stable. The domestic breeding demand is stable, and the downstream feed enterprise inventory is increasing. The market is concerned about the seasonal selling pressure of northeast corn before the Spring Festival and the downstream inventory - building situation [4][6] 3.2.2 Starch - The number of trucks arriving at Shandong deep - processing plants is increasing, and the Shandong corn spot is stable. The northeast starch spot is stable. The corn starch inventory has increased this week, with the manufacturer's inventory at 112.5 million tons, an increase of 0.2 million tons from last week, a monthly increase of 2.1%, and a year - on - year increase of 25.1%. The starch price depends on the corn price and downstream inventory - building. The by - product prices are strong, and the spot price difference between corn and starch is low. Due to the strong corn price, the starch spot is also strong, but enterprise profitability is declining. The 03 starch contract followed the market up and then down, and it is expected that the short - term rebound space for the 03 starch contract is limited [7] 3.3 Trading Strategies - Unilateral: 03 US corn has support at 430 cents per bushel. Start short - selling 03 corn and continue to short - sell 03 starch - Arbitrage: Stay on the sidelines [9][10] 3.4 Corn Options - Option strategy: Adopt a short - term cumulative put option strategy and conduct rolling operations [11] 3.5 Relevant Attachments - The report includes six charts showing the northern port corn closing price, corn 05 contract basis, corn 5 - 9 spread, corn starch 5 - 9 spread, corn starch 05 contract basis, and corn starch 05 contract spread [14][15][16][18][19]
