Report Summary - **Report Title**: PVC Weekly Report: Focus on the Sustainability of Export Rush, Trading in a Range - **Report Date**: February 8, 2026 - **Reporting Team**: Energy and Chemicals Team - **Analysts**: Guo Jianfeng, Guo Yanpeng, Li Qian 1. Report Industry Investment Rating No information provided. 2. Report's Core View - Short - term export rush and low valuation support the bottom of the PVC market, but attention should be paid to the post - holiday inventory accumulation. The domestic PVC supply is stable, domestic demand is in the seasonal off - peak, and exports are the key variable. Although the export rush supports the near - term price, there may be a marginal decline in the long - term, and the high - inventory pattern is hard to change. The cost side shows low valuation, and the market is expected to trade in a range [4]. 3. Summary by Relevant Catalogs 3.1 PVC Market Review - This week, PVC first rose and then fell, with the weekly line turning negative. It opened at 5040 at the beginning of the week, led the chemical sector's rise on Wednesday to a four - month high of 5178, then fell to a low of 4941 on Friday, and finally closed at 4981, with an amplitude of 237 points [3][8]. 3.2 Capital and Related Indicators - As of this Friday, the main contract's open interest was 1.1 million lots, at a high level for the same period. The V5 - 9 spread was - 113 yuan/ton as of this Friday, and on January 12, it once strengthened to - 40 yuan/ton due to export tariff news. Considering the short - term export demand front - loading effect, a long - short spread trade between May and September contracts can be considered [11][17]. 3.3 Valuation - As of this Thursday, the integrated profit of Shandong chlor - alkali was - 937 yuan/ton, still at a low level for the same period, and that of Northwest China was 926 yuan/ton, at a relatively low - to - neutral level for the same period. Shandong's industrial and commercial electricity price was 0.63 yuan/kWh (month - on - month decrease of 0.02), falling for three consecutive months; Inner Mongolia Western's industrial and commercial electricity price was 0.45 yuan/ton (month - on - month increase of 0.01), rising for two consecutive months [20][22]. 3.4 Supply - This week, PVC output was 480,000 tons (month - on - month increase of 0.2), with a cumulative year - on - year increase of 2.8%, remaining stable for seven consecutive weeks, and the capacity utilization rate was 79%. Only Formosa Plastics (82) in Taiwan and Tosoh (22) in Guangzhou have new planned maintenance in February [26]. 3.5 Domestic Demand - In 2025, the cumulative year - on - year growth rates of new construction, construction in progress, completion, and sales areas of real estate were - 20.4%, - 10.0%, - 18.1%, and - 8.7% respectively. The sales area has seen an expanding decline for eight consecutive months. The real estate transaction area is at a low level for the same period. In December 2025, the year - on - year growth rates of the price indices of newly built and second - hand residential buildings in 70 large and medium - sized cities were - 3.05% and 6.07% respectively, and the month - on - month growth rates were - 0.37% and - 0.70% respectively [31][34]. 3.6 External Demand - This week, the FOB price of Chinese calcium carbide, CFR price to India, and Southeast Asian price in January increased by $20, $20, and $0 per ton respectively. The Asian market price continued to rise, and the March contract price is expected to increase by $20 - 40 per ton. The Indian market price is rising, but demand is still insufficient. The US PVC market price is expected to rise further. In 2025, PVC exports were 3.82 million tons (year - on - year increase of 1.21 million tons, cumulative year - on - year increase of 46%). In January 2026, the average monthly export order volume was 62,000 tons (compared to 35,000 tons last year), and exports are expected to maintain high growth in the first quarter [37][42]. 3.7 Inventory - As of this Thursday, PVC enterprise inventory was 290,000 tons, decreasing for four consecutive weeks. The small - sample social inventory of PVC was 590,000 tons, the large - sample social inventory was 1.23 million tons, and the upper - middle - stream inventory was 1.52 million tons (week - on - week increase of 18,000 tons, year - on - year increase of 260,000 tons), rising for six consecutive weeks. It is expected that the social inventory will reach 1.38 million tons by the end of February [45][47]. 3.8 Caustic Soda Situation - This week, caustic soda output was 864,000 tons (month - on - month increase of 0.1), with a cumulative year - on - year increase of 5.6%, and the capacity utilization rate was 88%, at a high level for the same period. In 2025, caustic soda exports were 4.1 million tons (cumulative year - on - year increase of 34%). The current caustic soda factory inventory is 470,000 tons, with a month - on - month decrease of 49,000 tons, showing a high - level decline [58][60][63]. 3.9 Strategies - **Single - side trading**: Treat it as range - bound trading. Focus on the V2605 contract in the range of 4850 - 5100 yuan/ton. - **Hedging**: Since the futures market is in a contango structure, industrial customers can sell on rallies. - **Arbitrage**: The export rush supports the near - term price. Consider a long - short spread trade between the May and September contracts [5].

1. Report Industry Investment Rating - Not provided in the document 2. Core Viewpoints of the Report - The methanol market is currently influenced by geopolitical factors and the performance of the non - ferrous metals market. Unilateral trading is difficult as pricing power is not mainly in the industrial sector, and the trading rhythm is fast. The price center of the main methanol contract is rising. With the approach of the Spring Festival, downstream demand in Shandong has decreased, but overall demand remains okay. The 05 contract is facing downstream production, and the long - position expectations have not been falsified. It is recommended to hold an empty position during the holiday [2]. - The short - term trend of methanol is expected to be oscillating upwards, with a price range of 2100 - 2350. The recommended strategies are 3 - 5 reverse spreads and expanding MTO margins [14]. 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - The methanol market follows geopolitical and non - ferrous metal trends. The main change in fundamentals is that an Iranian ZPC device returned at 40% load last Wednesday. The 05 contract increased positions by over 50,000 lots on Wednesday night, and the industrial pricing is more reflected in the 5 - 9 reverse spread. The main methanol contract declined with the resumption of US - Iran negotiations and the fall of non - ferrous precious metals. Unilateral trading is difficult, and attention should be paid to both geopolitical and non - ferrous metal market changes. The price center of the main contract is rising. Although downstream demand in Shandong has decreased during the Spring Festival, overall demand is still acceptable, and the upstream inventory in the inland area is in a healthy state before the festival. The 05 contract is facing downstream production, and long - position expectations have not been falsified [2]. 3.1.2 Trading - Type Strategy Recommendations - **Base - price Strategy**: This week, the price of methanol 05 was 2245. After the price on the futures market rose and then fell, the 05 basis declined [12]. - **Spread Strategy**: This week, with the expectation of MTO shutdown, the 3 - 5 spread went into a reverse spread [13]. - **Trend Judgment and Strategy Suggestion**: The trend of methanol is expected to be oscillating upwards, with a short - term price range of 2100 - 2350. The recommended strategies are 3 - 5 reverse spreads and expanding MTO margins [14]. 3.1.3 Methanol Inland Inventory Situation - The inland methanol inventory situation is presented through multiple data charts, including the inventory of northwest methanol (excluding MTO), northwest MTO inventory, southern and northern line methanol plant inventories, national methanol plant inventory, national net plant inventory (plant inventory - pre - sales), and methanol northwest pending orders [20][24][29]. 3.1.4 Methanol Port Inventory Situation - The port inventory situation is shown through various data charts, including the weekly inventory seasonality of Chinese methanol ports (from Steel Union and SCI), the weekly inventory seasonality of methanol ports in different provinces, methanol downstream inventory in the East China region (excluding Shandong), methanol coastal available inventory, and methanol weekly arrival volume seasonality [36][52]. 3.2 This Week's Important Information and Next Week's Attention Events 3.2.1 This Week's Important Information - **Price Range Forecast**: The predicted price range of methanol is 2200 - 2500, with a current 20 - day rolling volatility of 20.01% and a historical percentile of 51.2% over three years [63]. - **Hedging Strategy Table**: For inventory management, when the finished - product inventory is high and there is a concern about methanol price decline, it is recommended to short methanol futures to lock in profits and buy put options while selling call options. For procurement management, when the procurement inventory is low, it is recommended to buy methanol futures to lock in procurement costs and sell put options to reduce costs [63]. - **Positive Information**: There is news that the Iranian opposition leader Reza Pahlavi called on workers in key oil, gas, and energy sectors to start a national - scale strike and hold large - scale demonstrations [64]. - **Negative Information**: Iran's shipments in January were 390,000 tons [65]. 3.2.2 Next Week's Important Events to Follow - Donald Trump expressed support for protesters and stated that the US is ready to provide assistance. The US government is discussing a possible strike against Iran, including air strikes on military targets, but no decision has been made [67]. 3.3 Disk Interpretation 3.3.1 Price - Volume and Capital Interpretation - In the inland area, the current methanol production is at an absolute high level, while winter is the traditional off - season for downstream demand. Downstream users' raw material inventories are generally high, and there is a phenomenon of vehicle congestion in some downstream sectors. Some olefin plants in the port area have shutdown plans, which will further weaken demand and significantly suppress market sentiment [68]. - This week, the 1 - 5 spread oscillated, mainly due to the increase in Iranian shipments [76]. 3.4 Price and Profit Analysis 3.4.1 Upstream and Downstream Price Tracking in the Industrial Chain - The document presents price trends of various products, including coal prices in Ordos and Qinhuangdao, methanol prices in the Lunan market and Taicang, and methanol warehouse receipts and related indicators [80][81][86]. 3.4.2 Upstream and Downstream Profit Tracking in the Industrial Chain - It shows the production costs and profit seasonality of methanol produced from different raw materials (coal, natural gas, and coke oven gas) in different regions, as well as the profit seasonality of downstream products such as MTO, acetic acid, MTBE, dimethyl ether, and formaldehyde [92][94][127]. 3.4.3 Upstream and Downstream Production and Yield Tracking in the Industrial Chain - It includes the weekly operating rates of major methanol enterprises, methanol production from different raw materials, and the operating rates of downstream products such as MTO and traditional downstream products [98][101][114]. 3.4.4 Import and Export Price and Profit Tracking - It presents the import volume seasonality of methanol from different countries, the external - market structure of methanol, and the import profit seasonality of Iranian methanol [132][134]. 3.4.5 Overseas Operating Rate Tracking - It shows the weekly capacity utilization rate seasonality of foreign methanol production, the overseas weekly production volume, and the operating rates of Iranian and non - Iranian methanol plants [136][137]. 3.5 Supply - Demand and Inventory Deduction - The supply - demand balance sheet shows the supply, demand, and inventory changes of methanol in ports from January 2025 to May 2026, including Iranian and non - Iranian imports, various demand items, and inventory consumption ratios [140].
