镍：基本面逻辑窄幅震荡，警惕消息面风险，不锈钢：宏观预期与现实博弈，钢价震荡运行

1. Report Industry Investment Rating No information provided in the given content. 2. Core Viewpoints of the Report - Nickel price: Under the fundamental logic, the nickel price is expected to fluctuate within a narrow range, and the long - term logic is under pressure. However, there are frequent developments in Indonesia, so it is necessary to be vigilant against the risk of news - driven stimulation. The global refined nickel's visible inventory is gradually increasing, which drags down the upside of the nickel price. The long - term low - cost supply increase may change the cost curve. In the short - term and for the second half of the year, the nickel price valuation is at the boundary of the nickel - iron conversion path. The relaxation of high inventory in the nickel - iron segment slightly boosts the upside of the nickel price, but the amplitude is limited. The decrease in the fire - method cash cost is about 2%, and it is still difficult for the price to drop sharply. The hype of nickel - ore contradictions may decline, restricting the price elasticity. Also, beware of potential policies in Indonesia, such as cracking down on illegal mining, changing the RKAB approval cycle, and the APNI's suggestion to re - evaluate the nickel - ore HPM formula [1]. - Stainless - steel price: The pressure in the real - world market needs to be continuously alleviated, and the steel price will fluctuate. The bullish logic focuses on the moderate decline of high inventory levels, with social inventory decreasing slightly for five consecutive weeks and factory inventory pressure easing in July. There are also some structural production cuts on the supply side. The bearish view is based on actual supply - demand, as the pressure relief needs to be sustainable, and the supply elasticity may limit the upside. The profit from warehouse delivery has narrowed to 2%. The stainless - steel production plan for August shows marginal increases, but the year - on - year growth is limited [2]. 3. Summary According to Relevant Catalogs 3.1 Fundamental Analysis Nickel - The global refined nickel's visible inventory is gradually increasing, dragging down the nickel price. The long - term low - cost supply increase may change the cost curve. In the short - term and for the second half of the year, the nickel price valuation is at the boundary of the nickel - iron conversion path. The relaxation of high inventory in the nickel - iron segment slightly boosts the upside of the nickel price, but the amplitude is limited. The decrease in the fire - method cash cost is about 2%, and it is still difficult for the price to drop sharply. The hype of nickel - ore contradictions may decline, restricting the price elasticity. Be vigilant against potential policies in Indonesia [1]. Stainless Steel - The bullish logic focuses on the moderate decline of high inventory levels, with social inventory decreasing slightly for five consecutive weeks and factory inventory pressure easing in July. There are also some structural production cuts on the supply side. The bearish view is based on actual supply - demand, as the pressure relief needs to be sustainable, and the supply elasticity may limit the upside. The profit from warehouse delivery has narrowed to 2%. The stainless - steel production plan for August shows marginal increases, but the year - on - year growth is limited [2]. 3.2 Inventory Changes - China's refined nickel social inventory increased by 1,963 tons to 41,286 tons, with warehouse - receipt inventory increasing by 1,520 tons to 22,141 tons, spot inventory increasing by 443 tons to 13,755 tons, and bonded - area inventory remaining unchanged at 5,390 tons. LME nickel inventory decreased by 570 tons to 211,662 tons [3][4]. - The nickel - iron inventory in mid - August was 33,111 tons, a 1% decrease from the previous half - month and a 45% increase year - on - year. The inventory pressure is high but has slightly eased [5]. - On August 14, 2025, the total stainless - steel social inventory was 1,078,900 tons, a 2.48% decrease from the previous week. Cold - rolled stainless - steel inventory was 610,718 tons, a 1.93% decrease, and hot - rolled stainless - steel inventory was 468,182 tons, a 3.19% decrease [5]. - The nickel - ore inventory at 14 ports in China increased by 618,200 wet tons to 10,951,600 wet tons, with 10,680,000 wet tons from the Philippines. By grade, low - nickel high - iron ore was 6,089,500 wet tons, and medium - and high - grade nickel ore was 4,862,100 wet tons [5]. 3.3 Market News - In March, the governor of Ontario, Canada, proposed to stop exporting nickel to the US in response to US tariff threats [6]. - In April, the first - phase project of Indonesia's CNI nickel - iron RKEF, EPC - contracted by China ENFI, successfully produced nickel - iron and entered the trial - production stage, with an annual metal - nickel output of about 12,500 tons per line [6]. - Environmental violations were found in the Morowali Industrial Park in Indonesia, and the relevant department may fine the verified illegal companies and conduct an audit of the entire park [6]. - Indonesia plans to shorten the mining - quota period from three years to one year to improve industry governance and better control coal and ore supplies [6]. - The APNI revealed that the government - approved 2025 RKAB production target is 364 million tons, higher than the 2024 target of 319 million tons [7]. - Two nickel - iron smelting industrial parks in Indonesia have suspended all EF production lines due to long - term losses, which is expected to affect the monthly nickel - iron output by about 1,900 metal tons [7]. - Indonesia's ESDM requires mining and coal - mining companies to resubmit the 2026 RKAB starting from October 2025 [7]. - A steel mill in Shandong started maintenance due to capacity restrictions, reducing the supply of hot - rolled coils and suspending long - term supply - agreement deliveries in August [8]. - The Indonesian president stated that they will crack down on illegal mining and have received reports on 1,063 illegal mines [9]. 3.4 Weekly Key Data Tracking The report provides data on the closing prices, trading volumes, price differentials, and other indicators of nickel and stainless - steel futures, as well as the prices of related products in the industrial chain, such as nickel imports, nickel - iron, stainless - steel products, high - carbon ferrochrome, and battery - grade nickel sulfate [10].
