1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - After the Iran - US conflict, crude oil prices are likely to fall. Geopolitical conflicts mainly cause short - term emotional premiums on oil prices, and the risk premium usually fades within a few weeks to 2 - 3 months. If the current conflict subsides quickly, Brent crude oil is likely to fall from the current high to the range of $62 - 73 per barrel [3][4]. - When crude oil prices fall, the crude oil chemical sector and futures will show a downward trend, with structural differentiation. Direct oil - chemical varieties will decline in sync with crude oil, while coal - chemical/light - hydrocarbon route varieties have stronger resistance to decline, and downstream processing links will see improved profitability [5][6]. - For stock index futures, it is expected that there will be further adjustments in the early trading session tomorrow, and it is recommended to adopt a strategy of shorting at high and buying at low for the time being. Gold is expected to continue with a slightly bullish and volatile trend. Iron ore is in a high - level wide - range oscillation, and the right - side signal is yet to come. Glass should be treated as wide - range oscillation before the upper pressure is broken. Methanol is in a high - level oscillation. Pulp futures are in an interval oscillation [7][11][12][16][18][20]. 3. Summary According to the Catalog I. After the Iran - US conflict, crude oil prices are likely to fall - Geopolitical conflicts on oil prices are mostly short - term emotional premiums rather than long - term trends. After most Middle - East geopolitical events, the crude oil risk premium will quickly be reversed within a few weeks to 2 - 3 months and return to the pricing based on supply - demand fundamentals [4]. - If the current conflict subsides quickly and the Strait of Hormuz resumes navigation, Brent crude oil is likely to fall from the current high to the range of $62 - 73 per barrel, and the geopolitical premium will fade. Only when there is a substantial long - term blockade or continuous interruption of supply in core oil - producing areas can oil prices remain high for a long time, but the probability of this scenario is currently low [4]. II. The trends of the crude oil chemical sector and futures when crude oil prices fall - The crude oil chemical futures as a whole will follow the decline of crude oil but show structural differentiation. Direct oil - chemical varieties such as naphtha cracking, pure benzene, ethylene glycol, PTA, PP/PE will see weakened cost support and their prices will fall in sync with crude oil. The larger the previous increase, the more obvious the decline [5]. - Coal - chemical/light - hydrocarbon route varieties such as coal - based olefins and methanol have relatively independent costs, stronger resistance to decline, and a smaller decline compared with pure oil - chemical varieties. Downstream processing links such as plastic and rubber products will see relieved cost pressure, improved marginal profitability, and smoother price transmission [6]. III. Key influencing factors and rhythm - The speed of premium fading: The faster the conflict subsides, the steeper the decline of crude oil and chemical futures, and the main decline is usually completed within 1 - 4 weeks [6]. - Inventory and positions: The concentrated closing of previous profit - taking positions will amplify short - term fluctuations, and the market will gradually return to the supply - demand logic after the decline [6]. - Macroeconomics and supply - demand: If the global crude oil inventory rises, OPEC+ increases production, or strategic reserves are released, it will accelerate the decline of oil prices. If the demand side remains stable, the decline will be more moderate [6]. Technical Analysis - Stock index futures: It is expected that there will be further adjustments in the early trading session tomorrow, and it is recommended to adopt a strategy of shorting at high and buying at low for the time being. The Shanghai Composite Index is still within the 15 - minute oscillation range [7][8]. - Gold: Gold has stabilized in the daily - level oscillation. After a higher opening, it showed an oscillating trend throughout the day. It should be treated with a slightly bullish and volatile mindset in the future [11]. - Iron ore: Australia and Brazil's shipments maintain a normal rhythm. In the medium - to - long - term, it is in the period of mine production capacity release, and the expectation of loose supply still exists. The resumption of production of steel mills after the festival may have a certain driving effect, but the start of terminal demand still takes time. Attention should be paid to the influence of policy and sentiment. Technically, it is in a high - level wide - range oscillation, and the right - side signal is yet to come [12][13]. - Glass: The daily melting volume has declined slightly, and the inventory has been slightly reduced. Attention should be paid to the resumption progress of deep - processing enterprises after the festival. In the short term, it is more affected by the overall sentiment of commodities. Technically, it should be treated as wide - range oscillation before the upper pressure is broken [16][17]. - Methanol: Iran is China's largest source of methanol imports, accounting for over 70%. The obstruction of shipping in the Strait of Hormuz and the expected maintenance of Iranian facilities have led to a sharp increase in the expectation of import supply contraction, which is the core driver of this round of price increase. However, if the price remains high for a long time, terminal demand will be suppressed, forming a negative feedback. It should be treated as high - level oscillation [18]. - Pulp: The trading sentiment in the spot market is average. Domestic pulp enterprises' production is within the normal range, and the pulp output will not change much. The inventory in domestic ports has started to accumulate, and the pressure remains. The previously shut - down facilities of downstream paper mills are gradually resuming production, and the overall pulp consumption continues to rise. The futures market has shown an interval oscillation recently [20].

Report Industry Investment Ratings - Red stars represent a predicted upward trend, green stars represent a predicted downward trend. One star indicates a bullish/bearish bias with a driving force for price increase/decrease but limited operability on the market. Two stars mean holding a long/short position with a clear upward/downward trend and the market is in the process of development. Three stars represent a clearer long/short trend and there are still relatively appropriate investment opportunities. White stars indicate a relatively balanced short - term long/short trend with poor operability on the current market, suggesting to wait and see [10]. - For example, propylene, pure benzene, styrene, PTA, short - fiber, methanol are rated ★☆☆; plastic, PVC, caustic soda, urea, glass are rated ★★★; ethylene glycol, bottle - chip are rated ★★★; soda ash is rated ★☆☆ [1] Core Viewpoints - The overall market is affected by multiple factors such as geopolitical situations, supply - demand relationships, and policy regulations. Different chemical products show different trends and investment opportunities [2][3][5][6][7][8] Summary by Category Olefins - Polyolefins - Propylene futures' main contracts opened high and closed low. There are many planned plant shutdowns, so the supply is expected to decline. Short - term production enterprise shipments have improved, and the demand has also increased [2]. - Plastic and polypropylene main contracts also opened high and closed low. For polyethylene, supply pressure is not large due to more maintenance and less imported goods. Demand from the spring plowing and packaging film industries is stable or increasing.
