The supply-side contraction-induced cyclical inflection point of oil prices has not been seen yet, and a weak and volatile judgment on crude oil is maintained [2] - High-sulfur fuel oil is still supported by geopolitical factors in the short term, but the medium-term supply pattern tends to be loose. Low-sulfur fuel oil has been strong recently due to supply-side fluctuations, but medium-term supply pressure still exists [2] - The cost support for asphalt has been continuously weakening, the demand is expected to follow the seasonal weakening pattern, and the medium- and long-term fundamentals have a bearish impact on BU [3] - The supply and demand of liquefied petroleum gas have tightened marginally, and it is expected to fluctuate strongly [4] Summary by Related Catalogs Crude Oil - Since the end of October, the oil price has continued to show a weak and volatile performance. Geopolitical risks have boosted the oil price, but the rebound height has always been limited [2] - According to the monthly reports of the three major institutions, considering the suspension of production increases by OPEC+ in the first quarter of next year and the strict implementation of production cut compensation, the global oil market will have a supply surplus of 1.84 million barrels per day and 3.31 million barrels per day this year and next year respectively [2] - The supply-side contraction-induced cyclical inflection point of oil prices has not been seen yet, and a weak and volatile judgment on crude oil is maintained [2] Fuel Oil & Low-Sulfur Fuel Oil - High-sulfur fuel oil is still supported by geopolitical factors in the short term. The subsequent actual exports of Russia still have uncertainties, but the medium-term supply pattern tends to be loose [2] - Low-sulfur fuel oil has been strong recently due to supply-side fluctuations, but the possible increase in low-sulfur shipping volume caused by the planned maintenance of the RFCC unit of the Kaigute refinery at the end of December needs attention, and medium-term supply pressure still exists [2] Asphalt - In November, the discount of diluted asphalt dropped to -$11 per barrel, and the cost support has been continuously weakening [3] - Since November, the weekly shipment volume has decreased month-on-month and is also at a low level in the same period of the past four years [3] - The "14th Five-Year Plan" end-year rush demand expectation has been falsified, and the subsequent demand will follow the seasonal weakening pattern. The medium- and long-term fundamentals have a bearish impact on BU [3] Liquefied Petroleum Gas - The increase in propane discount supports the import landed cost [4] - The improvement in the profitability of butane dehydrogenation units has boosted the enthusiasm of downstream chemical enterprises to start operations, and the demand on the combustion side has improved [4] - The supply and demand of liquefied petroleum gas have tightened marginally, and it is expected to fluctuate strongly [4]

Report Industry Investment Ratings - Crude oil: ★☆☆, indicating a bullish/ bearish bias with a driving force for price movement, but limited operability in the market [1] - Fuel oil: ★☆☆, similar to crude oil, with a bias but limited operability [1] - Low - sulfur fuel oil: ★☆☆, same as above [1] - Asphalt: ★☆☆, with a bias but limited operability [1] - Liquefied petroleum gas: ☆☆☆, suggesting a relatively balanced short - term trend with poor operability and a wait - and - see approach [1] Core Viewpoints - The global oil market will have supply surpluses of 1.84 million barrels per day and 3.31 million barrels per day this year and next year respectively, and the surplus will gradually expand quarter by quarter. There is still a downward risk in the crude oil market this year [1] - The fuel oil market is affected by geopolitical factors, and the upward drive for high - sulfur cracking is limited. The low - sulfur market has improved fundamentals [2] - The 2601 asphalt contract has some support at 3000 yuan/ton, and the fundamental bearish factors still suppress the market in the medium - to - long term [3] - The LPG market is expected to fluctuate strongly due to tightened supply - demand margins [3] Summary by Related Catalogs Crude Oil - Based on the latest adjustments of the supply - demand balance sheets by three major institutions in November, considering OPEC+ suspending production increases and strictly implementing production cut compensation in the first quarter of next year, the global oil market will have supply surpluses of 1.84 million barrels per day and 3.31 million barrels per day this year and next year respectively. The supply surplus will gradually expand quarter by quarter, and the most relaxed quarter (Q1 next year) has not arrived yet. Since the fourth quarter, the inventory accumulation rate of global oil at 2.4% has exceeded that of the previous three quarters, and the supply surplus is increasingly evident in the inventory. There is still a downward risk in the crude oil market this year, and attention should be paid to the realization of geopolitical risks related to Venezuela [1] Fuel Oil & Low - Sulfur Fuel Oil - The drone attack on Russia's Novorossiysk today damaged the oil terminal facilities, driving up the prices of crude - related products, and fuel oil followed suit. In terms of fundamentals, high - sulfur fuel oil is still supported by geopolitical factors in the short term. Sanctions and attacks on Russia continue to disrupt the supply side, and the possible further sanctions on Venezuela by the US also bring uncertainties. However, the actual reduction in supply needs further observation. The demand side is at the end of the power - generation peak season, and the increase in Middle - East supply offsets the impact, and the demand for refinery feedstock is also weak, so the upward drive for high - sulfur cracking is limited. The low - sulfur market has seen a relief in supply pressure due to unstable operation of overseas refineries. The strengthening of the crack spreads of gasoline and diesel provides support from the perspective of production conversion. Coupled with the peak season of bunker fuel demand in the fourth quarter and the easing of Sino - US trade relations, the fundamentals have improved compared with the previous period [2] Asphalt - The 2601 contract has some support at 3000 yuan/ton. The worse - than - expected shipment volume not only disproves the expectation of rush - demand in the final year of the "14th Five - Year Plan" but also sends a negative signal that the demand is lower than the same period last year. The destocking of the latest commercial inventory continues to slow down, and the year - on - year increase in social inventory has widened after reaching an inflection point of being higher than the same period last year at the end of October. In the medium - to - long term, the bearish fundamentals still suppress the BU market [3] Liquefied Petroleum Gas - The international LPG market has been trending strongly recently, and the supply of imported resources is tight. The improved profitability of butane dehydrogenation plants has boosted the enthusiasm of downstream chemical enterprises to start production, and the significant cooling in many places has led to an improvement in combustion - end demand. The storage capacity utilization rates of refineries and ports have decreased. The tightening of supply - demand margins has boosted the LPG market to be regarded as fluctuating strongly [3]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The overall energy - chemical market shows a volatile trend. Crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefins, and PVC are all expected to run in a volatile manner, with different influencing factors for each variety [1][3][5][7]. 3. Summary by Directory 3.1 Research Views - **Crude Oil**: On Tuesday, oil prices rebounded. WTI December contract rose $0.91 to $61.04 per barrel, a 1.51% increase; Brent January contract rose $1.1 to $65.16 per barrel, a 1.72% increase; SC2512 closed at 468.9 yuan per barrel, up 9.7 yuan or 2.11%.

Although the production in November has decreased, the short - term supply still faces pressure. The price of asphalt is treated with a bearish view [3]. - **Polyester**: TA601 and EG2601 closed down. PX&TA futures prices rebounded, and the processing margin on the disk narrowed. The supply side has maintenance plans, and the downstream polyester maintains a high operating rate. It is expected that PX&TA will follow the cost side to fluctuate in the short term. The supply pressure of ethylene glycol remains, and the price is expected to be under pressure [3]. - **Rubber**: On Tuesday, the main rubber contracts on the Shanghai Futures Exchange declined. The rubber production is seasonally increasing, and the supply pressure is increasing. The downstream demand is weak overseas, and the EU's investigations have increased export concerns. It is expected that rubber prices will fluctuate [5]. - **Methanol**: The supply in the domestic market has recovered to a high level, and Iranian devices may stop production from late November to December. It is expected that methanol will maintain a bottom - oscillating trend [5]. - **Polyolefins**: The short - term production will remain high, and the downstream demand will weaken marginally after the e - commerce activities. It is expected that polyolefin prices will enter a volatile and weak stage [7]. - **PVC**: The supply maintains a high - level oscillation, the domestic demand slows down, and exports are affected by India's anti - dumping policy. It is expected that PVC prices will tend to oscillate at the bottom [7]. 3.2 Daily Data Monitoring - The report provides the basis price data of energy - chemical varieties on November 12, 2025, including spot prices, futures prices, basis, basis rates, and their changes and historical quantiles [10]. 3.3 Market News - Last week, US crude inventory was expected to increase, and gasoline and distillate inventories were expected to decline.
