镍：宏观情绪提振预期，现实限制弹性空间，不锈钢：现实与宏观博弈，钢价震荡运行

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The fundamentals of Shanghai nickel are characterized by the resonance of macro and news factors, while the real - world fundamentals limit its price elasticity. The fundamentals of stainless steel show that macro expectations boost the market, but the actual supply - demand situation still exerts a drag. The price of nickel and stainless steel is expected to show an oscillatory pattern [1][2]. Summary by Related Catalogs Nickel Fundamentals - Macro and news factors improve market sentiment, with policies potentially adjusting the structure and optimizing supply. The Indonesian APNI Association suggests re - evaluating the HPM formula for nickel ore, which may increase smelting costs. However, the support from the ore end has weakened, and the smelting end limits the upward elasticity of nickel prices. The negative feedback in July has affected the supply side, and the acceptance of high smelting prices in the ternary sector is low [1]. Stainless Steel Fundamentals - U.S. tariffs suppress the terminal demand for stainless steel, but domestic policy expectations boost the market. The real - world supply - demand situation has turned into a double - weak state, with weekly inventory slightly decreasing. The production schedule in July shows a decline in China and an increase in Indonesia. The high - cost cash cost of Indonesian stainless steel has decreased, and the high inventory of nickel - iron pressures its valuation [2]. Inventory Changes - China's refined nickel social inventory increased by 1,674 tons to 38,979 tons, LME nickel inventory increased by 1,398 tons to 207,576 tons. The mid - July nickel - iron inventory was 37,534 tons, with a year - on - year increase of 50% and a month - on - month decrease of 11%. On July 17, 2025, the total social inventory of stainless steel decreased by 1.69% week - on - week. China's port nickel ore inventory increased by 518,700 wet tons to 9.4836 million wet tons [3][4][6]. Market News - There are various events such as the potential halt of nickel exports from Ontario to the U.S., the successful trial production of a nickel - iron project in Indonesia, the resumption of production of a nickel smelter, the shutdown and maintenance of a cold - rolling mill, the removal of the raw ore export ban in the Philippines, environmental violations in an Indonesian industrial park, the plan to shorten the mining quota period in Indonesia, and the suspension of production of some nickel - iron EF lines due to losses [7][8][9]. Weekly Key Data Tracking - The report provides data on the closing prices, trading volumes, and related price differences of Shanghai nickel and stainless steel futures, as well as prices and spreads in the industrial chain such as electrolytic nickel, nickel - iron, and stainless steel products [11].
