1. Report Industry Investment Rating - No relevant content provided 2. Core View of the Report - The Fed's future interest rate cut expectations support precious metal prices. Economic and employment data are mixed, which disturbs the probability of the Fed cutting interest rates in December. Global central banks' continuous gold purchases and geopolitical risks may support precious metal prices in the medium to long term. The supply - demand expectations of platinum and palladium are different, and their prices may be adjusted due to various factors such as interest rate expectations and supply - demand changes [1] 3. Summary by Related Catalogs 3.1 Precious Metal Market Data - **Shanghai Gold**: On December 3, 2025, the closing price was 956.70 yuan/g, the trading volume was 273,359.00, and the inventory was 90,873.00 (ten - gram). Compared with the previous week, the closing price increased by 9.54 yuan/g, and the trading volume decreased by 26,737.00 [1] - **Shanghai Silver**: The closing price of the futures active contract was 13,423.00 yuan/ten - gram, the trading volume was 2,664,403.00, and the inventory was 626,633.00 (ten - gram). Compared with the previous week, the closing price increased by 159.00 yuan/ten - gram, and the trading volume increased by 2,464,589.00 [1] - **COMEX Gold**: The closing price of the futures active contract was 4,133.80 dollars/ounce, the trading volume was 169,613.00, and the inventory was 36,573,657.72 (troy ounces). Compared with the previous week, the closing price increased by 101.00 dollars/ounce, and the trading volume decreased by 42,456.00 [1] - **COMEX Silver**: The closing price of the futures active contract was 58.93 dollars/ounce, the trading volume was 107,261.00, and the inventory was 455,933,737.28 (troy ounces). Compared with the previous week, the closing price decreased by 0.22 dollars/ounce, and the trading volume decreased by 4,787.00 [1] 3.2 Important Information - Bessent downplayed the Fed Chairman's control over interest rates and proposed setting a residency limit for regional Fed presidents, saying that tariffs could be re - structured. The US ADP employment in November unexpectedly declined, with a decrease of 32,000 jobs, the largest decline since March 2023. However, the US ISM services PMI expansion speed was the fastest in nine months, the price index was at a seven - month low, and the employment index was at a six - month high [1] 3.3 Gold and Silver - **Multi - empty Logic**: US economic and employment data in November were mixed, disturbing the probability of the Fed cutting interest rates in December. But the probability of a December rate cut was still over 80%. Fiscal stimulus policies in multiple countries led to expectations of debt expansion and fiscal deficits, and central banks' continuous gold purchases and geopolitical risks may support precious metal prices in the medium to long term [1] - **Trading Strategy**: Buy on price dips. For London gold, pay attention to the support level around 3,800 - 4,000 dollars/ounce and the resistance level around 4,300 - 4,600 dollars/ounce. For Shanghai gold, the support level is around 890 - 920 yuan/g and the resistance level is around 970 - 1,000 yuan/g. Similar support and resistance levels are provided for silver [1] 3.4 Platinum - **Multi - empty Logic**: Supply is affected by high mining costs, unstable power supply, etc., and demand is expected to increase due to stricter emission standards. The supply - demand of platinum is expected to be tight from 2025 - 2026. However, the expectation of the Bank of Japan raising interest rates and high platinum prices may suppress downstream demand, leading to price adjustments [1] - **Trading Strategy**: Hold previous long positions cautiously or take profits on rallies. Consider the "long platinum, short silver" arbitrage opportunity. For London platinum, pay attention to the support level around 1,300 - 1,500 dollars/ounce and the resistance level around 1,800 - 2,000 dollars/ounce. For domestic platinum, the support level is around 335 - 385 yuan/g and the resistance level is around 465 - 516 yuan/g [1] 3.5 Palladium - **Multi - empty Logic**: Supply is affected by mining difficulties but may increase due to vehicle scrapping. Demand from the automotive industry is expected to decline, and the supply - demand of palladium is expected to shift from tight to loose from 2025 - 2026. Interest rate expectations and supply - demand changes may lead to price adjustments [1] - **Trading Strategy**: Hold previous long positions cautiously or take profits on rallies. For London palladium, pay attention to the support level around 1,190 - 1,390 dollars/ounce and the resistance level around 1,600 - 1,800 dollars/ounce. For domestic palladium, the support level is around 305 - 357 yuan/g and the resistance level is around 415 - 465 yuan/g [1]

1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints - The current silicon market maintains a pattern of weak supply and demand, and there is still pressure above the silicon price. Attention should be paid to the subsequent registration of new warehouse receipts and the actual start - up of silicon enterprises [1] - The willingness of downstream enterprises to replenish inventory is limited, and there is great pressure for the spot price to continue to rise, which suppresses the upward space of the futures price. Attention should be paid to the subsequent launch of the polysilicon platform and the evolution of macro - sentiment [1] 3. Summary by Relevant Catalogs Industrial Silicon Price Changes - The average price of non - oxygenated 553 (East China) remained flat at 9,350 yuan/ton, and the average price of 421 (East China) industrial silicon rose 0.51% to 9,800 yuan/ton. The closing price of the futures main contract fell 0.61% to 8,920 yuan/ton [1] Supply and Demand - In terms of supply, the suspension of production of silicon enterprises in the southwest production period has basically been implemented, and the start - up is at a low level within the year. The start - up in the north is relatively stable. It is expected that the output of industrial silicon in December will fluctuate slightly around 400,000 tons. In terms of demand, polysilicon enterprises maintain a production - reduction trend, silicone enterprises have reached a joint production - reduction mechanism, and the demand for industrial silicon may weaken. Silicon - aluminum alloy enterprises purchase as needed, and the downstream's willingness to stock up at a low level is limited [1] Investment Strategy - The overall situation is a pattern of weak supply and demand, with pressure above the silicon price. The trading strategy is range operation [1] Polysilicon Price Changes - The prices of N - type dense material, N - type re - feeding material, N - type mixed material, and N - type granular silicon remained flat. The closing price of the futures main contract rose 1.98% to 57,430 yuan/ton [1] Supply and Demand - On the supply side, silicon material enterprises maintain a production - reduction trend, but some silicon material factories may have new production capacity put into operation. After offsetting, it is expected that the output in October will still increase slightly, and the output in November will decrease to about 120,000 tons. On the demand side, the prices in the industrial chain are under pressure to decline. Although the polysilicon price is still firm, the market transactions are relatively light, with few new transactions, and the downstream has strong resistance to high - price resources [1] Investment Strategy - The overall situation is that the downstream's willingness to replenish inventory is limited, and there is great pressure for the spot price to continue to rise, which suppresses the upward space of the futures price. The trading strategy is to wait and see for now [1] Other Information - In October 2025, the import of complete vehicles was 43,000 units, a month - on - month increase of 5.6% and a year - on - year decrease of 0.3%. The import amount was $2 billion, a month - on - month decrease of 2.1% and a year - on - year decrease of 16.3%. From January to October 2025, the import of complete vehicles was 404,000 units, a year - on - year decrease of 30%, and the import amount was $20.25 billion, a year - on - year decrease of 38.3% [1] - Germany's Jülich Research Center announced that its developed silver - free heterojunction (HJT) solar cell achieved a world - record efficiency of 23.08% using a full - copper (Cu) metallization process. Compared with the benchmark device using full - silver (Ag) metallization, the efficiency only decreased by 0.4% [1]

Industry Investment Rating - No information provided Core View - The upward space of the methanol 01 contract is quite limited. The main reasons are that the overall profit of downstream MTO is poor, and if the methanol price rises further, it may lead to downstream parking and negative demand feedback; downstream replenishment willingness is weak due to profit levels and high inventory, and inland profit is poor, which restricts the performance of inland methanol prices [1] Summary by Related Catalogs Price Changes - Methanol futures prices: MA01 decreased by 4 yuan/ton (-0.19%) to 2132 yuan/ton; MA05 remained unchanged at 2232 yuan/ton; MA09 decreased by 9 yuan/ton (-0.40%) to 2228 yuan/ton [1] - Methanol spot prices: Increases in various regions, such as 12.5 yuan/ton (0.59%) in Taicang, 10 yuan/ton (0.45%) in Shandong, 15 yuan/ton (0.72%) in Guangdong, etc. [1] - Coal spot prices: Decreases in various regions, such as 2.5 yuan/ton (-0.42%) for Bu Shui Duo Si Q5500, 10 yuan/ton (-1.50%) for Datong Q5500, etc. [1] - Industrial natural gas prices: Remained unchanged in Hohhot and Chongqing [1] Profit Situation - Methanol production profit: Coal - based methanol profit increased by 72.6 yuan/ton (42.91%) to 241.8 yuan/ton; natural gas - based methanol profit remained unchanged at - 1270 yuan/ton [1] - Downstream profit: Decreases in most downstream products, such as 13.8 yuan/ton (-6.87%) for Northwest MTO, 22 yuan/ton (-2.78%) for East China MTO, etc. [1] Important Information - Domestic: The main methanol contract MA2601 showed a strong sideways trend, opening at 2134 yuan/ton, closing at 2132 yuan/ton, up 11 yuan/ton, with trading volume of 1.1983 million lots and open interest of 0.9786 million lots, showing increased volume and decreased open interest [1] - Foreign: Six methanol plants with a total capacity of 9.9 million tons in a Middle - Eastern country are still under maintenance, and the remaining plants are operating at low loads.

Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints - For lead, the price oscillated and declined. Considering the tight raw material supply and reduced supply, the downside space for lead prices is limited. It is recommended to wait and see for now [1]. - For zinc, the mine supply is continuously tightening, and the TC is likely to fall. It may have an impact on the supply side, providing some support for zinc prices. It is advisable to conduct range - bound operations, and also wait and see for now [1]. 3. Summary by Related Content Lead - **Price and Market Data**: On December 3, 2025, the average price of SMM1 lead ingots was 17,050 yuan/ton, up 0.44%; the closing price of the main futures contract of Shanghai lead was 17,210 yuan/ton, up 0.79%. The trading volume of the active futures contract was 52,077 lots, up 34.28%; the open interest was 47,601 lots, up 0.88%. The LME inventory remained unchanged at 256,950 tons, and the Shanghai lead warehouse receipt inventory decreased by 9.43% to 18,131 tons [1]. - **Fundamentals**: There is no expected increase in lead concentrate imports, and the processing fee is likely to rise. However, it has not yet had a substantial impact on smelter operations. Last week, more smelters were under maintenance, and the production of primary lead decreased. In the secondary lead sector, a smelter in Yunnan reduced production due to maintenance. The lead price fell below 17,000 yuan, and smelters were reluctant to sell at low prices. The inventory of primary lead increased, while that of secondary lead decreased. The consumption of electric bicycle batteries is gradually weakening, while the automotive battery market is approaching the traditional replacement peak season [1]. Zinc - **Price and Market Data**: On December 3, 2025, the average price of SMM1 zinc ingots was 22,670 yuan/ton, up 0.80%; the closing price of the main futures contract of Shanghai zinc was 22,745 yuan/ton, up 0.69%.

The demand is still weak, and the construction in the north has stopped due to cold weather, and some downstream operations have been affected by environmental protection [1]. Industry News - Saudi Arabia has launched a tender for three mineral exploration licenses, covering an area of 13,000 square kilometers. The country is accelerating the exploitation of deposits estimated at 9.4 trillion riyals (2.50 trillion US dollars), including areas with potential for gold, silver, copper, zinc, and lead mining [1]. - A zinc mine in South China resumed production after maintenance in November, with an expected increase of about 2,000 metal tons of zinc concentrate. A zinc mine in North China will undergo a 10 - day maintenance in December, with an expected reduction of about 500 metal tons of zinc concentrate. A zinc mine in Central China has gradually resumed production after maintenance, with an expected increase of about 1,000 metal tons of zinc concentrate [1].
