Report Information - Report Title: Nickel Daily Report [1] - Date: August 1, 2025 [2] - Research Team: Non - ferrous Metals Research Team [3] - Researchers: Yu Feifei, Zhang Ping, Peng Jinglin [3] Core Viewpoint - On the 31st, black - series commodities tumbled, and Shanghai nickel showed weakness, closing below the 120,000 mark again. The main contract 2509 closed down 1.79% at 119,830, with the total open interest of the index increasing by 11,234 to 190,329 lots. The nickel surplus pattern remains unchanged, and prices declined again after the cooling of macro - sentiment. The overall surplus pattern of nickel is still significant, and the nickel price is temporarily regarded as weak [8]. Section Summaries 1. Market Review and Operational Suggestions - **Market Performance**: On the 31st, black - series commodities fell generally, and Shanghai nickel was weak. The main 2509 contract closed down 1.79% at 119,830, and the total open interest of the index increased by 11,234 to 190,329 lots [8]. - **Supply - side Situation**: There are expectations of loose supply from the mining ends in the Philippines and Indonesia, and the probability of subsequent decline in ore prices is high. Under the pressure of losses, some production lines in Indonesia have switched to producing high - grade nickel matte, driving a slight recovery in the low - level nickel - iron price. On the 31st, the average price of 8 - 12% high - nickel iron was reported at 912.5 yuan per nickel point, but the acceptance of high - price nickel ore remains low [8]. - **Demand - side Situation**: The stainless - steel market is still weak, in the traditional off - season of consumption with high inventory. As the nickel - iron price rises, some downstream enterprises prefer to purchase scrap stainless steel for production, and the acceptance of high - nickel pig iron prices is also poor. The price of battery - grade nickel sulfate remained flat at 27,370 yuan per ton on the 31st, and it stopped falling and rebounded in the short term supported by the rigid replenishment demand of precursors and the low inventory of nickel salt plants [8]. 2. Industry News - **Indonesian Investment**: Indonesia's national investment management agency Danantara is exploring investment opportunities in the nickel downstream industry. It is considering acquiring the PT Gunbuster Nickel Industry (GNI) smelter. Danantara expects to prepare an investment plan of over $20 billion and provide about $60 million in medium - term financing through a syndicated loan [9][10]. - **Battery Energy Storage**: Bulgaria officially launched the largest - scale operating battery energy storage system in the EU, with a capacity of 124 megawatts/496.2 megawatt - hours.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The nickel price is expected to fluctuate within a range due to the resonance of macro and news factors, with the policy expectations of macro - structural adjustment and supply optimization fermenting, but the logic between fundamental verification and macro expectations may fluctuate before clear policies on nickel are implemented. The nickel ore support is weakening, and the low - cost supply increment of refined nickel and high inventory in the ferronickel segment have an impact on the price [1]. - The marginal direction of stainless steel prices is dominated by macro sentiment, and the elasticity of the real - world fundamental logic is poor. The macro policy expectations on the domestic supply - side boost commodities, but a clear policy is needed for a trend - upward movement. The supply - demand of stainless steel shows a double - weak pattern, and the price is expected to follow the macro sentiment and fluctuate within a range [2]. 3. Summaries by Related Catalogs 3.1 Nickel Fundamentals - **Macro and News Factors**: Macro policy expectations are fermenting, but no clear policies on nickel have been implemented. Short - term policy news from Indonesia is frequent but within market expectations.

Refined nickel inventory is stable in the short term, but the expected increase in low - cost supply is a drag. Ferronickel inventory is high, but marginal restocking slightly boosts the price [1]. 3.2 Stainless Steel Fundamentals - **Macro and Real - world Logic**: Macro sentiment dominates the marginal direction of steel prices. The real - world fundamental logic has poor elasticity. The macro policy expectations on the supply - side boost commodities, but specific policies are needed for a trend - upward movement [2]. - **Supply - demand Situation**: The supply - demand of stainless steel shows a double - weak pattern. The resonance production cuts in China and Indonesia from June to July have alleviated the over - supply situation.
