Report Overview - Report Title: Fuel Oil and Low-Sulfur Fuel Oil Weekly Report [1] - Author: Liang Kefang from Guotai Junan Futures Research Institute [1] - Date: September 14, 2025 [1] 1. Report Industry Investment Rating - Not provided in the content 2. Core Views - This week, the prices of fuel oil and low-sulfur fuel oil fluctuated widely with increased volatility, and the price center generally moved downward. For high-sulfur fuel oil, Middle East exports remained high, and the window transaction premium was weak, indicating weak spot market transactions. The domestic inventory was replenished in the early stage, and the near-month contracts were continuously suppressed. The domestic and international prices are expected to have limited improvement in the short term. However, there is a possibility that the US and Europe may increase sanctions on Russia, which will bring significant uncertainty to the high-sulfur supply and support prices. For low-sulfur fuel oil, in addition to the continuous supply recovery in Japan, Brazil's exports to the Asia-Pacific region also increased since the end of August. Coupled with some European arbitrage supplies in transit, the Asia-Pacific spot prices are expected to remain weak. The amount of the new quota is still one of the core factors affecting LU valuation. If the quota increases significantly year-on-year, given the high inventory in Zhoushan, the pattern of loose or even surplus supply will have an obvious negative impact on the LU market. Since the issuance time and specific scale of the new quota are still highly variable, continuous observation is needed [4]. - Valuation: FU is estimated to be in the range of 2650 - 2900, and LU in the range of 3300 - 3500 [4]. - Strategies: 1) Unilateral: FU is expected to oscillate strongly in the short term, while LU is relatively weak. 2) Inter-period: FU and LU will maintain their current structures. 3) Inter-variety: The cracking spread of FU will oscillate at a high level; the LU - FU spread may rebound [4]. 3.

1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints of the Report - The lead market is rated as neutral, with a price range of 16,900 - 17,500 yuan/ton [3] - Supply logic has marginally improved, which will support prices. The production of primary lead is under pressure, and secondary lead enterprises are in a continuous loss state. Some regions are stockpiling lead concentrates for winter, intensifying the raw material shortage. The consumption of lead-acid batteries has recovered, and the finished product inventory of some battery factories has decreased [6] - From a supply - demand perspective, domestic lead inventories have slightly increased. The long - position to inventory ratio of the SHFE lead contract for October is relatively high, and the spot discount has narrowed. Overall, the supply shortage of lead concentrates and the marginal improvement in consumption, along with the enhanced expectation of Fed rate cuts and domestic favorable policies, will support the price in the short - term. In unilateral trading, existing long positions should be held, and new long positions should wait for a good entry point. There are still opportunities for positive spreads in SHFE lead term contracts [6] 3. Summaries by Relevant Catalogs 3.1 Transaction Aspects: Price, Spread, Inventory, Capital, Transaction Volume, Open Interest - **Price**: The closing price of the SHFE lead main contract last week was 17,040 yuan/ton, with a weekly increase of 0.83%.

The open interest was 52,188 lots, an increase of 2762 lots from the previous week. The trading volume of LmeS - Lead 3 was 6480 lots, an increase of 870 lots from the previous week, and the open interest was 142,000 lots, an increase of 6194 lots from the previous week [7] 3.2 Lead Supply: Lead Concentrates, Scrap Batteries, Primary Lead, Secondary Lead - **Lead Concentrates**: The spot import TC of 60% lead concentrate remained at - 90 dollars/ton this week. The domestic lead concentrate processing fee decreased by 50 to 350 yuan/ton. Some regions are stockpiling lead concentrates for winter, intensifying the raw material shortage [6][7] - **Primary Lead and Secondary Lead**: The production of primary lead is under pressure, with smelters in Henan under continuous maintenance and a smelter in Qinghai about to start maintenance. Secondary lead enterprises have been in a loss state, but the profit situation has started to improve, and some enterprises in Anhui and Hubei have resumed production [6] - **Scrap Batteries and Secondary Lead**: The price of scrap batteries has been under continuous pressure, and the smelting profit situation has started to improve. The raw material inventory of secondary lead smelting enterprises shows a certain trend [38] 3.3 Lead Demand: Lead - Acid Batteries, End - Users - **Lead - Acid Batteries**: The consumption peak season of lead - acid batteries fell short of expectations, and the operating rate of lead - acid battery enterprises only increased seasonally.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - This week, the alloy prices fluctuated. The increase in the cost side pushed the price center slightly higher, but Hegang's entry for inquiries may set the tone for the latest steel mill tenders, causing a slight market slowdown. Attention should be paid to Hegang's final quoted price [5]. - The resumption of production in steel mills after the military parade led to a recovery in hot metal production, supporting the demand for raw materials. The upward shift in the cost center provided short - term support for alloy prices [5]. Summary by Directory 1.

Core Views of the Report - The consumption side of zinc has slightly improved, and the operating rate has rebounded, with a neutral strength analysis [2]. - The inventory accumulation rhythm continues, and the galvanizing operating rate has slightly increased [3]. - Domestic zinc supply has increased as expected. With the increase in zinc concentrate supply, smelters and port zinc concentrate inventories are relatively abundant. However, there will be some maintenance in September, leading to a month - on - month contraction in supply. The consumption side has slightly improved, but terminal demand is relatively weak. In the short term, zinc prices may fluctuate within a narrow range, and in the medium to long term, a short - selling strategy on rallies is recommended. For internal and external strategies, SHFE zinc may be relatively weaker during the period of increased domestic supply and decreased demand, and short - term (within a quarter) positive spread positions can be held [5]. 3.
