液化石油气（LPG）投资周报：地缘风险事件再驱动，LPG价格持续反弹-20251027

1. Report Industry Investment Rating - The report does not explicitly mention the industry investment rating. 2. Core View of the Report - Affected by the sharp rebound in crude oil prices and the cooling in coastal areas, the valuation of the LPG futures market has rebounded this week, with a high monthly spread and strong spot prices. However, the increase in raw material prices has also pressured the deep - processing plants. Although the previously shut - down plants have resumed normal operation and the operating rate has increased, the plant profit losses have intensified. Currently, the fundamental structure of LPG has not changed, traditional demand has not yet spread, and chemical demand shows rigid characteristics. Attention should be paid to the negative feedback effect of continuous losses in downstream plant profits and the impact of the PN spread remaining below $50 on the raw material procurement of cracking plants [5]. 3. Summary by Relevant Catalogs 3.1 Energy and Chemical Product Price Monitoring - The report provides the closing price, daily, weekly, monthly, and annual changes of various energy and chemical products such as exchange rates, precious metals, and energy commodities. For example, the current price of LPG is 4,258 yuan/ton, with a daily increase of 0.52%, a weekly increase of 0.90%, a monthly increase of 0.31%, and an annual decrease of 8.07% [3]. 3.2 LPG Market Analysis 3.2.1 Supply - Last week, the total commercial volume of liquefied gas was about [missing value] tons, including [missing value] tons of civil gas, [missing value] tons of industrial gas, and [missing value] tons of ether - post C4. The arrival volume of liquefied gas last week was [missing value] tons. Although some plants in East China, Northeast China, and Shandong resumed operation, a refinery in South China had partial equipment under maintenance and some enterprises used resources internally, resulting in a decrease in supply. This week, production enterprises have no plans to start or shut down, but some enterprises still use resources internally, so the domestic commercial volume is expected to decline [5]. 3.2.2 Demand - In October, the combustion demand for liquefied gas is in the off - season as the heating season has not yet arrived. In the C4 deep - processing sector, the demand for n - butane is insufficient, the plant profit losses have intensified, and the economic efficiency has weakened. In the C3 deep - processing sector, the demand for alkanes has rebounded month - on - month, but the continuous losses in plant profits have dampened the production enthusiasm of enterprises due to the sharp increase in raw material prices and unchanged terminal demand structure [5]. 3.2.3 Inventory - Last week, the in - plant inventory of LPG was [missing value] tons, and the port inventory was [missing value] tons. This week, the storage capacity utilization rate of the domestic liquefied gas market has decreased. In some areas, the inventory has slightly increased due to the impact of imported resources and adverse weather conditions, while other areas have successfully reduced inventory through low prices and low supply. The port inventory has generally shown a downward trend [5]. 3.2.4 Basis and Position - The weekly average basis is [missing value] yuan/ton in East China, [missing value] yuan/ton in South China, and [missing value] yuan/ton in Shandong. The total number of LPG warehouse receipts has increased by [missing value] to [missing value] hands, and the lowest deliverable location is [missing value] [5]. 3.2.5 Chemical Downstream - The operating rates of PDH, MTBE, and alkylation are [missing value]%, [missing value]%, and [missing value]% respectively. The profits of PDH - to - propylene, MTBE isomerization, and alkylation in Shandong are [missing value] yuan/ton, [missing value] yuan/ton, and [missing value] yuan/ton respectively [5]. 3.2.6 Valuation - The PG - SC ratio is [missing value], and the PG monthly spread is [missing value] yuan/ton. Affected by geopolitical factors, the oil prices have rebounded sharply this week, and the PG - SC cracking spread has narrowed [5]. 3.2.7 Other Factors - The Fourth Plenary Session of the 20th Central Committee has clarified the development goals and key tasks for the 15th Five - Year Plan period. The meeting between the US and Russian presidents at the Budapest Summit in Hungary has been postponed, and there is currently no plan for a meeting between the two presidents. The military confrontation between the US and Venezuela has intensified, and there have been continuous market news disturbances. Europe and the US have imposed sanctions on two Russian refineries, and India has re - planned its energy procurement plan [5]. 3.3 LPG Price and Spread Analysis - The report provides the prices, price changes, and spreads of LPG futures contracts at different times. For example, on October 24, 2025, the price of PG01 is 4,050 yuan/ton, with a weekly increase of 2.92% and a monthly decrease of 5.42%. The monthly spread between PG01 and PG02 is 107 yuan/ton, with a weekly increase of 10.31% and a monthly increase of 67.19% [10]. 3.4 Refinery Equipment Maintenance Plan - The report lists the maintenance plans of major and local refineries in China, including the refinery name, location, maintenance equipment, maintenance capacity, start time, and end time [11]. 3.5 LPG Plant and PDH Device Maintenance Data - It provides the maintenance data of LPG plants and PDH devices, including the production enterprise, location, maintenance equipment, normal production volume, loss volume, start time, and end time [12]. 3.6 International LPG - Related Price and Spread Analysis - The report includes the price trends and spreads of CP propane, CP butane, FEI propane, FEI butane, MB propane, MB butane, etc., as well as the price ratios of these products to WTI and Brent crude oil [13][20][24]. 3.7 LPG Market Consumption and Inventory Analysis - It analyzes the consumption and inventory of LPG, including the apparent consumption, production, sales rate, and inventory in different regions such as North China, East China, South China, and Shandong [135][137]. 3.8 LPG Deep - Processing Profit Analysis - The report analyzes the profits of alkane and olefin deep - processing, including PDH - to - propylene, PDH - to - PP, MTBE, and alkylation oil [193][206][212].
