Report Summary 1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints - As of the close on March 27, domestic futures contracts showed mixed performance. Some commodities like pure benzene and lithium carbonate had significant increases, while others such as container shipping on the European route and caustic soda declined. Futures contracts of stock indexes and treasury bonds also had different trends. The market was affected by factors such as supply - demand, geopolitical situation in the Middle East, and seasonal factors [6][7]. - The prices of most commodities were expected to be volatile due to the tense situation in the Middle East, especially the situation in the Strait of Hormuz, which had a great impact on the supply of energy - related commodities. Some commodities were expected to have a strong - side oscillation, but risks needed to be controlled [12][14][15]. 3.

The copper concentrate inventory was relatively low. The production of electrolytic copper increased. The demand from the copper product sector started to pick up, but the terminal data was not optimistic. The inventory decreased, and the price was expected to fluctuate due to the situation in the Middle East [9]. - **Lithium Carbonate**: The price of lithium carbonate rose by over 6% on March 27. The production in March decreased month - on - month. The import volume in February increased year - on - year. The downstream lithium battery production was in high - growth, but the retail of new - energy vehicles decreased year - on - year. The market was affected by the situation in Zimbabwe and the overall upward trend of non - ferrous metals, but there were potential supply risks [11]. - **Crude Oil**: The U.S. crude oil inventory increased more than expected. The Strait of Hormuz was almost closed, which led to production cuts in Middle - Eastern oil - producing countries. Although some measures were taken to relieve the supply pressure, the situation was still tense. The possibility of a U.S. - Iran negotiation was low, and the oil price was at a high - risk of fluctuation [12][14]. - **Asphalt**: The asphalt production rate decreased, and the planned production in April was significantly lower. The downstream demand started to recover after the Spring Festival. The inventory rate decreased slightly. The supply was affected by the situation in the Middle East, and the price was expected to oscillate strongly [15]. - **PP (Polypropylene)**: The downstream PP开工率 increased slightly, but the demand recovery was slow. The enterprise开工率 was at a low level. The cost was affected by the Middle - East situation. The supply was expected to decrease, and the price was expected to oscillate strongly [16][17]. - **Plastic**: The plastic开工率 decreased, and the downstream开工率 increased but did not return to the pre - holiday level. The cost was affected by the Middle - East situation. The supply was expected to decrease, and the price was expected to oscillate strongly [18][20]. - **PVC**: The PVC开工率 increased, and the downstream开工率 also increased but was still lower than the same period last year. The export price increased, but the inventory was still high. The industry had an anti - involution expectation, and the supply was expected to decrease if the Strait of Hormuz did not resume navigation [21]. - **Coking Coal**: The coking coal price decreased on March 27. The mine production resumed smoothly, and the inventory was transferred from mines to downstream. The price decline was a correction after the previous over - rise, and the downward space was expected to be limited [22][23]. - **Urea**: The urea price rose on March 27. The domestic supply was guaranteed by high production and state - reserve goods. The downstream demand was mainly from compound fertilizer factories and other industries. The inventory decreased, and the price was expected to oscillate at a narrow high level [24].
