1. Report Industry Investment Rating - The investment view on LPG is bearish [4] 2. Core Viewpoints of the Report - Crude oil production increases, suppressing the cost side, leading to LPG prices running at a low level. OPEC+ plans to increase production in September, and the international oil and gas supply is expected to be loose, suppressing the raw material cost price. Although the recent resumption of PDH has increased and the deep - processing of C4 has maintained stable operation, the terminal demand remains weak, and the overall fundamentals are loose. The basis is at a high level, and the valuation of the main contract is suppressed by the warrants, with the reverse spread reaching the bottom [4] 3. Summary According to Relevant Catalogs 3.1 Market Review - The main contract of LPG futures declined, with a fluctuation range of 3,820 - 4,000 yuan/ton. The sharp drop in August CP led to a significant decline in import costs, which was negative for the futures and spot markets. International crude oil prices fell, causing a decline in the energy - chemical sector. The main LPG contract reached a low for the year. As the decline in spot prices was less than that of futures, the basis strengthened. The weekly average basis was 518.6 yuan/ton in East China, 515.2 yuan/ton in South China, and 651.2 yuan/ton in Shandong. The lowest deliverable location was South China [6] 3.2 Factors Affecting LPG 3.2.1 Supply - Last week, the total commercial volume of LPG decreased slightly. The commercial volume of domestic LPG decreased, with the volume of domestic - use gas at 210,000 tons (3.62%), industrial gas at 202,200 tons (- 0.39%), and ether - after C4 at 74,000 tons (- 0.56%). The arrival volume of LPG last week was 650,000 tons. A company in the Northwest resumed operation, a company in Shandong carried out maintenance, and a refinery in Central China increased internal supply [4] 3.2.2 Demand - The combustion demand remained weak, and downstream procurement demand was low. In the olefin deep - processing sector, the poor performance of the oil product market increased the inventory pressure of domestic deep - processing enterprises, weakening the demand for ether - after C4. In the alkane deep - processing sector, the concentrated restart of PDH increased the operating rate, but the off - season demand for intermediate - link propylene and terminal PP was average, and the fundamentals were loose, with other downstream profits in varying degrees of loss [4] 3.2.3 Inventory - Last week, the in - plant inventory of LPG was 175,800 tons (- 2.77%), and the port inventory was 321,620 tons (61%). This week, the inventory in various domestic regions remained generally stable with minor adjustments. The inventory in South China and Northeast China increased slightly due to import impacts and low demand, while the inventory in East China and Central China decreased through resource shipping and low - price sales. Although the number of arriving ships at the port decreased slightly this period, the unloading volume increased compared with last week, and the import resources were sufficient [4] 3.2.4 Basis and Positions - The weekly average basis was 555.4 yuan/ton in East China, 547.6 yuan/ton in South China, and 40 yuan/ton in Shandong. The total number of LPG warrants was 10,179 lots, and the lowest deliverable location was East China [4] 3.2.5 Chemical Downstream - The operating rates of PDH, MTBE, and alkylation were 73.84%, 53%, and 50% respectively. The profits of PDH - to - propylene, MTBE isomerization, and alkylation in Shandong were - 201 yuan/ton, - 200 yuan/ton, and - 390 yuan/ton respectively [4] 3.2.6 Valuation - The PG - SC ratio was 2.59%, and the PG continuous - first to continuous - second monthly spread was - 478 yuan/ton. The basis level was high, and the main futures contract was expected to reach the bottom [4] 3.2.7 Other Factors - OPEC+ plans to increase production by 547,000 barrels per day in September, the fundamentals of crude oil remain loose, the demand in the refined oil market is weak, and international oil and gas prices are fluctuating downward. Trump signed an executive order on August 6, imposing a 25% tariff on Indian goods exported to the US, raising the overall tariff level to 50%. The 90 - day tariff relaxation period is approaching, and China - US tariff renegotiations are imminent [4] 3.3 Investment and Trading Strategies - The investment view is bearish. The trading strategy suggests temporarily waiting and watching for unilateral trading, paying attention to the positive spread of far - month contracts for arbitrage, and shorting PDH profits by going long on PG and shorting PL. Attention should be paid to China - US tariff policies, US sanctions on Iran, and changes in downstream demand [4] 3.4 Device Maintenance Plans - The report provides the maintenance plans of major refineries, LPG production devices, and PDH devices in China in 2025, including information such as refinery names, locations, maintenance devices, processing capacities, start and end times, etc. [12][13][14] 3.5 Market Data Charts - The report includes a large number of market data charts, covering the closing price monitoring of energy - chemical products, LPG futures prices, inter - month and cross - month spreads, domestic and international LPG - related price trends, inventory, production, consumption, and other data [3][10][18]
