1. Report Industry Investment Rating Not provided in the given content. 2. Core View of the Report - The overall energy and chemical products should be treated with an oscillatory mindset as macro - data starts to reflect the weakening economic situation. The chemical sector shows a weaker trend than crude oil, and the market is still dominated by the pessimistic expectation of future demand [2]. 3. Summary by Variety Crude Oil - **View**: There is still an expectation of supply surplus, and attention should be paid to macro and geopolitical disturbances. The price of crude oil will continue to oscillate under the balance of OPEC+ production - increasing pressure and macro - geopolitical benefits [5]. - **Main Logic**: The EIA short - term energy outlook continues to lower the expected production of the US next year, and the API data shows that the US destocked crude oil and restocked refined oil last week, with relatively weak terminal demand. Although the recent macro - environment has eased and Saudi Arabia's production increase in May was limited, the supply surplus expectation still exists in the second half of the year due to the cumulative effect of production increase [5]. LPG - **View**: The domestic combustion and chemical demand remain weak, with limited upward rebound space and may oscillate at the bottom in the short term [9]. - **Main Logic**: Domestic refineries are gradually resuming from maintenance, increasing the supply of liquefied gas and civil gas, and the refinery inventory is rising. High temperatures reduce the civil combustion demand, and the downstream restocking willingness is limited. The PDH device operating rate has declined slightly, and the port inventory is rising, with limited incremental demand for propane [9]. Asphalt - **View**: The absolute price of asphalt is over - estimated, and the asphalt monthly spread is expected to decline with the increase of warehouse receipts [5]. - **Main Logic**: The increase in heavy - oil supply due to OPEC+ production increase and the improvement of domestic raw material supply will put pressure on asphalt prices. The current asphalt is over - estimated, and it needs both strong crude oil and rebar for a bull market, but the current situation does not support it [5][6]. High - Sulfur Fuel Oil - **View**: It will oscillate weakly as the supply increases and demand decreases, and the geopolitical impact on prices is short - term [6][7]. - **Main Logic**: The increase in heavy - oil supply, the rise in import tariffs, and the substitution of natural gas for oil power generation will put pressure on high - sulfur fuel oil prices. The current strong cracking spread and weak discount are due to different factors, and the three driving forces supporting high - sulfur fuel oil are weakening [6][7]. Low - Sulfur Fuel Oil - **View**: It will follow the crude oil price to oscillate, with increasing supply, falling demand, and may maintain a low - valuation operation [8][9]. - **Main Logic**: Currently, the supply and demand of low - sulfur fuel oil are both weak. The reduction of domestic refined - oil export tax rebates and the cancellation of UCO export tax rebates will increase the supply pressure, which is likely to be transmitted to low - sulfur fuel oil [8][9]. Methanol - **View**: It will oscillate in the short term [17]. - **Main Logic**: The methanol price oscillated on June 10. The port inventory is entering a restocking cycle, and the coal price has a short - term rebound, which has a slight impact on methanol. The olefin market is still weak, providing limited support for methanol [17]. Urea - **View**: The domestic supply is strong and demand is weak, and the futures price will oscillate weakly [17]. - **Main Logic**: The high supply continues, and the agricultural demand has not seen concentrated replenishment yet, while the industrial demand is weakening. Exports are expected to be reflected in late June, and the enterprise inventory is rising [17]. Ethylene Glycol - **View**: It has support at the 4200 - 4300 level, and short - selling is not recommended [13]. - **Main Logic**: The industrial pattern of ethylene glycol is still healthy from June to July. The possible stagnation of US ethane exports may limit future production, and the downward space is limited [13]. PX - **View**: It will oscillate weakly as the supply restarts quickly, and attention should be paid to PTA production and polyester start - up [11]. - **Main Logic**: The cost - end guidance of PX is slowing down due to the uncertain future OPEC+ production policy and concerns about global demand. The Asian PX operating load will increase, and the domestic PX is in a destocking cycle, but the supply - demand game is intensifying [11]. PTA - **View**: The supply increases and demand decreases, and the situation is gradually weakening [11]. - **Main Logic**: The weaving load is declining due to limited orders and high inventory. The PTA supply is restarting, and the supply - demand weak expectation restricts the market sentiment, and the destocking is narrowing in June [11]. Short - Fiber - **View**: The processing fee is supported by production cuts, and the absolute value follows the raw material price [13][14]. - **Main Logic**: The PF fundamentals are improving marginally. The supply pressure is relieved due to production cuts, and the spot basis is strengthening. The short - term decline is driven by the macro - environment, and the industrial pattern is still healthy [13][14]. Bottle Chip - **View**: It will oscillate and follow the raw material price [15]. - **Main Logic**: After the price decline, the trading volume of bottle chips has increased, and the basis has strengthened. Exports have diverted some of the excess supply, but it is not enough to change the weak situation. The scope of production cuts and maintenance may expand [15][16]. PP - **View**: It will oscillate in the short term [20]. - **Main Logic**: The cost - end support is marginally increasing, but the supply is still increasing, and the downstream demand is weak. The high - speed growth of supply continues, and the upstream refinery profit may need to be further compressed to balance the supply [20]. Plastic - **View**: It will oscillate as the improvement of maintenance is limited [19]. - **Main Logic**: The cost - end valuation support is marginally increasing, but the plastic's own fundamentals are still under pressure. The supply pressure is high, the downstream demand is weak, and the export window has not widened significantly [19]. Styrene - **View**: It rebounded due to macro - expectations, but the subsequent driving force is insufficient and will oscillate weakly [11][12]. - **Main Logic**: The macro - meeting and device rumors drove the rebound. However, the real - world benefits are limited, the supply may increase due to the restart of long - stopped devices, and the demand and inventory situation of styrene and its downstream products are not optimistic [11][12]. PVC - **View**: It will have a weak rebound in the short term due to improved sentiment, but may face pressure in the long term [22]. - **Main Logic**: The market sentiment has improved due to Sino - US talks. However, in the long term, new production capacity will be put into operation, the domestic demand is in the off - season, and exports are expected to weaken. Although there are many maintenance plans in June, the production will increase after the new capacity is put into operation in mid - July [22]. Caustic Soda - **View**: The spot price has peaked, and it is advisable to short on rallies [22]. - **Main Logic**: The non - aluminum demand is entering the off - season, and the receiving price of Weiqiao has started to decline. Although there are many maintenance plans in June, the supply is expected to increase in the third quarter. The current supply and demand are both weak, and the 09 - contract fundamentals are pessimistic [22]. 4.

Core Viewpoint - The article emphasizes the need for targeted measures to address the frequent occurrence of monopoly cases in the public utility sector, alongside continuous improvement of regulatory frameworks and strict enforcement of regulations [3][8]. Regulatory Framework Improvement - Continuous enhancement of the regulatory framework is essential, as highlighted by the "Regulations on Prohibiting the Abuse of Market Dominance" issued by the State Administration for Market Regulation in March 2023, which mandates public utility operators to operate legally and not abuse their market dominance [4]. - The implementation opinions approved by the Central Committee in November 2023 stress the need for regulation of monopolistic and competitive business scopes in natural monopoly sectors, preventing the extension of monopolistic advantages into competitive areas [4][5]. Strengthening Supervision - The meeting organized by the State Administration for Market Regulation emphasizes the importance of public utility operators enhancing their awareness of responsibilities and adhering to antitrust compliance, while also strengthening antitrust enforcement in the sector [6]. - Recent typical cases published by regulatory bodies serve as warnings to operators and remind local governments of their responsibilities in preventing monopolistic behaviors [6]. Fundamental Solutions to Monopoly Issues - The article identifies two main reasons for the prevalence of monopolies in the public utility sector: the unique nature of the sector, which often involves exclusive agreements with the government, and the tendency of companies to extend their monopolistic advantages into related areas for additional profits [7]. - It is noted that local government factors, both explicit and implicit, often contribute to the occurrence of monopolistic cases, complicating the resolution of these issues [8].
