Report Information - Report Title: Black Series Weekly Report [2] - Report Date: October 31, 2025 [2] - Analyst: Shi Lei [2] - Research Assistant: Shi Zhuoran [2] Industry Investment Rating - Not provided Core Views - Mid - to - Long - Term: For steel and iron ore, the "Golden September and Silver October" period is over, macro - level positive impacts are weakening, and the market is returning to fundamental influences. With increasing environmental restrictions and approaching winter storage, there is an expectation of a mild rebound in steel and iron ore futures, but trading should be based on an oscillatory mindset. For glass and soda ash, glass inventory has stopped increasing and started to decline, with stable supply and weak downstream demand, maintaining a weak pattern. Soda ash has a slight reduction in inventory, weak downstream demand, and a supply - surplus situation, with the main contract continuing a weak oscillatory trend [62][66] - Short - Term: For black series products, influenced by the "14th Five - Year Plan" on new infrastructure and stable real estate policies and the easing of Sino - US trade relations, the overall market showed an oscillatory upward trend this week, but cooled on Friday. Steel, hot - rolled coils, and iron ore are expected to oscillate, with risks of repeated fluctuations. Glass and soda ash followed the sector up and then down, with prices under pressure, and short - term trading should be based on fundamental logic [63][67] Summary by Directory Black Series Weekly Market Review | Variety | Futures Closing Price (10/24/2025) | Futures Closing Price (10/31/2025) | Change | Percentage Change | Spot Price | Basis (Unconverted) | | --- | --- | --- | --- | --- | --- | --- | | Rebar (RB2601) | 3046.0 | 3106.0 | 60.0 | 2.0% | 3230.0 | 124.0 | | Hot - rolled Coil (HC2601) | 3250.0 | 3308.0 | 58.0 | 1.8% | 3330.0 | 22.0 | | Iron Ore (I2601) | 771.0 | 800.0 | 29.0 | 3.8% | 814.0 | 14.0 | | Coke (J2601) | 1757.5 | 1777.0 | 19.5 | 1.1% | 1670.0 | - 107.0 | | Coking Coal (JM2601) | 1248.5 | 1286.0 | 37.5 | 3.0% | 1450.0 | 164.0 | | Glass (FG601) | 1092.0 | 1083.0 | - 9.0 | - 0.8% | 1210.0 | 127.0 | | Soda Ash (SA601) | 1229.0 | 1225.0 | - 4.0 | - 0.3% | 1270.6 | 45.6 | [3] Rebar - Blast Furnace Profit: On October 30, the rebar blast furnace profit was - 58 yuan/ton [7] - Supply Side: As of October 31, the blast furnace operating rate was 81.75%, a decrease of 2.96 percentage points; the daily average pig iron output was 2.3636 million tons, a decrease of 35,400 tons; the rebar output was 2.1259 million tons, an increase of 55,200 tons [12] - Demand Side: In the week of October 31, the apparent consumption of rebar was 2.3218 million tons, a week - on - week increase of 61,700 tons; as of October 30, the trading volume of construction steel by mainstream traders was 90,196 tons [16] - Inventory: In the week of October 31, the social inventory of rebar was 4.3081 million tons, a week - on - week decrease of 66,800 tons; the in - plant inventory was 1.7171 million tons, a week - on - week decrease of 129,200 tons [21] Iron Ore - Supply Side: In the week of October 24, the global iron ore shipment volume was 3.3884 million tons, a week - on - week increase of 54,900 tons; the arrival volume at 47 ports in China was 2.0843 million tons, a week - on - week decrease of 592,000 tons [26] - Inventory: In the week of October 31, the inventory of imported iron ore at 47 ports in China was 15.27293 million tons, a week - on - week increase of 163,440 tons; the inventory of imported iron ore at 247 steel enterprises was 8.84986 million tons, a week - on - week decrease of 229,330 tons [31] - Demand Side: In the week of October 31, the average daily discharge volume of imported iron ore at 47 ports in China was 331,220 tons, a week - on - week increase of 91,500 tons; as of October 30, the trading volume at major Chinese ports was 74,000 tons [36] Float Glass - Supply Side: In the week of October 31, the number of operating float glass production lines was 226; the weekly output was 1,128,925 tons, unchanged from the previous week; as of October 30, the capacity utilization rate was 80.63%, unchanged; the operating rate was 76.35%, unchanged [41] - Inventory: In the week of October 31, the in - plant inventory of float glass was 65.79 million weight boxes, a decrease of 823,000 weight boxes compared to October 24; the available days of in - plant inventory were 28 days, a week - on - week decrease of 0.3 days [46] Soda Ash - Supply Side: In the week of October 31, the capacity utilization rate of soda ash was 86.89%, an increase of 1.95 percentage points from the previous week; the output was 757,600 tons, an increase of 17,000 tons from the previous week [50] - Inventory: As of October 31, the in - plant inventory of soda ash was 1.702 million tons, a week - on - week decrease of 10 tons [55] - Production and Sales Rate: As of October 31, the production and sales rate of soda ash was 100.01%, a week - on - week increase of 0.23 percentage points [59]
