Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Nickel prices are expected to oscillate within a narrow range. The support logic at the ore end is weakening, and the smelting logic restricts the price elasticity. The global refined nickel inventory is gradually increasing, which puts downward pressure on nickel prices. In the short term, it is difficult for nickel prices to drop significantly, but there is also an upper limit. The inventory at the ferronickel link has slightly decreased, which slightly boosts the upside space of nickel prices, but the increase is limited. The fundamentals lack obvious contradictions, and the price movement is mainly influenced by the macro - sentiment of the sector. There are also some uncertainties in the news, such as Indonesia's possible adjustment of the RKAB approval cycle and the APNI's proposal to re - evaluate the nickel ore HPM formula [1]. - In the stainless - steel market, the tug - of - war between bulls and bears is intensifying, and steel prices are expected to fluctuate. The bulls focus on the decline in high - level inventories and potential supply - side production cuts, while the bears are concerned about the actual supply - demand situation, such as the profit from warehousing and the still - high inventory levels. Overall, steel prices are likely to move in a volatile manner [2]. Summary According to Related Catalogs Nickel and Stainless - Steel Fundamentals - **Nickel fundamentals**: The support from the ore end has weakened, and the smelting logic restricts price fluctuations. The global refined nickel inventory is gradually rising, which suppresses nickel prices. In the short term, it's hard for nickel prices to fall sharply, but there is an upper ceiling.

The news about Indonesia's possible adjustment of the RKAB approval cycle and the APNI's proposal to re - evaluate the nickel ore HPM formula adds uncertainties [1]. - **Stainless - steel fundamentals**: The bulls are concerned about the decline in high - level inventories and potential supply - side production cuts, such as the maintenance of a Shandong steel mill and the phased production cuts in Guangxi. The bears focus on the actual supply - demand situation, including the profit from warehousing and the still - high inventory levels. Overall, steel prices are expected to fluctuate [2]. Inventory Changes - China's refined nickel social inventory decreased by 536 tons to 38,578 tons, with warehouse receipt inventory down 573 tons to 21,374 tons, spot inventory up 437 tons to 12,014 tons, and bonded area inventory down 400 tons to 5,190 tons.
