Core View of the Report - The energy and chemical sector is in a complex situation. Chemical products generally follow the strong trend of crude oil. The geopolitical risk between Iran and Israel has intensified, leading to increased volatility in crude oil prices, which in turn affects the prices of downstream chemical products [1][2]. - The overall outlook for the energy and chemical sector is a strong - oscillating trend, and a long - short allocation strategy is recommended [3]. 3. Summary by Relevant Catalogs 3.1 Market Views 3.1.1 Crude Oil - On June 19, SC2508 closed at 570.9 yuan/barrel, up 3.29%, and Brent2508 closed at 78.74 dollars/barrel, up 3.5%. - Geopolitical concerns in the Middle East dominate short - term oil price fluctuations. Although there have been attacks on energy infrastructure, there has been no substantial impact on crude oil production. Oil prices are expected to oscillate with high volatility [6]. 3.1.2 Asphalt - The main asphalt futures closed at 3695 yuan/ton. Spot prices in East China, Northeast China, and Shandong were 3770 yuan/ton, 3990 yuan/ton, and 3800 yuan/ton respectively. - Due to the escalation of the Iran - Israel geopolitical situation, asphalt prices have a geopolitical premium.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - For crude oil, due to the unclear outcome of the US - Iran negotiation, although OPEC has shown clear production - increase data, considering the bottom - support effect of shale oil and the uncertainty of the US - Iran negotiation, the current risk - return ratio is not suitable for short - chasing, and short - term observation is recommended [1]. - For methanol, with sufficient domestic supply and a weak macro - environment, there may be a further decline. It is recommended to focus on short - selling opportunities on rallies. For cross -品种 trading, pay attention to the opportunity of going long on the 09 - contract PP - 3MA spread on dips [3]. - For urea, with high supply and lukewarm demand, the price is expected to have no obvious trend. Given the low basis at the same period, there is no safety margin for long - trading, so short - term observation is recommended [5]. - For rubber, after an oversold rebound, the price is oscillating. Short - long or neutral strategies with short - term operations are recommended. Also, pay attention to the band - trading opportunity of going long on RU2601 and shorting on RU2509 [11]. - For PVC, under the expectation of strong supply and weak demand, the market is expected to be weakly oscillating in the short term, but beware of rebounds if the weak export expectation fails to materialize [13]. - For polyethylene, the price is expected to remain oscillating in June as the short - term contradiction shifts from cost - driven decline to high - maintenance - boosted inventory reduction, and there is no new capacity - commissioning plan [16]. - For polypropylene, due to planned capacity expansion in June and a seasonal decline in demand, the price is expected to be bearish in June [17]. - For PX, the de - stocking is expected to slow down in June as the maintenance season ends, but it will re - enter the de - stocking cycle in the third quarter. The price is expected to oscillate at the current valuation level [19]. - For PTA, with supply still in the maintenance season and moderate inventory pressure in the polyester and chemical fiber sector, PTA will continue to de - stock, and the processing fee is supported. The price is expected to oscillate at the current valuation level [20]. - For ethylene glycol, the industrial fundamentals are still in the de - stocking stage, but the de - stocking of port inventory is expected to slow down. There is a risk of valuation correction as the maintenance season ends [21].
