During the recent oil price decline, shale oil production did not significantly decrease. OPEC exports have increased, but most are absorbed by China, so there is no obvious visible inventory in the market. In Europe, the overall refined oil inventory is in a low - level destocking state, and the crude oil inventory has increased, but refinery demand is about to enter the peak season, and the diesel crack spread remains high [7]. - Market analysis: Since July, crude oil prices have gradually weakened and then consolidated in a range.

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - The LPG market shows a divergence between weak propane and strong butane, with the valuation of domestic PG rising. Although the CP price dropped significantly at the beginning of the month, the continuous increase in upstream crude oil production and the oversupply in the market led to a weak performance of chemical products. However, the PG valuation has been repaired this week. Overall, there are few short - term positive factors for PG, and its price is expected to remain in a low - level oscillation. Attention should be paid to the flow of warehouse receipts on the disk, as well as macro and geopolitical risks [4][5] 3. Summary According to Related Catalogs 3.1 Energy and Chemical Product Price Monitoring - The report monitors the closing prices of various energy and chemical products, including exchange rates, precious metals, crude oil, and chemical products. For example, the current price of LPG is 4,220 yuan/ton, with a daily decline of 1.12%, a weekly increase of 3.69%, a monthly decline of 0.59%, and an annual decline of 9.48% [3] 3.2 LPG Market Analysis - **Supply**: It is bearish.

The arrival volume of LPG last week was 560,000 tons (no change). Some manufacturers in South China and North China increased the commercial volume [4] - **Demand**: It is neutral. In October, the combustion demand for LPG is in the off - season. In the deep - processing of C4, the demand for n - butane is insufficient, and the device profit loss intensifies. In the deep - processing of C3, the demand for alkanes is weak, and the operating rate has decreased [4] - **Inventory**: It is bullish. Last week, the factory inventory of LPG was 184,100 tons (a 3.56% decrease), and the port inventory was 3.1804 million tons (a 3.01% decrease). The domestic LPG market storage capacity utilization rate decreased this week, with a slight increase in inventory in Shandong and Central China, and a relatively smooth inventory reduction in East and South China [4] - **Basis and Position**: It is neutral. The weekly average basis in East China is 200.40 yuan/ton, in South China is 345.00 yuan/ton, and in Shandong is 173.00 yuan/ton.
