Investment Rating - The report maintains a "Positive" investment rating for the polycarbonate (PC) industry [10] Core Insights - The demand for PC has been steadily growing, while the current supply expansion cycle is nearing its end. Chinese companies have broken the overseas monopoly, significantly increasing self-sufficiency. The industry has reduced its reliance on imports, and future capacity additions are expected to be limited. By 2025, the capacity utilization rate is projected to reach 85%. Global demand is expected to grow steadily, with no new PC capacity anticipated in China by 2026. Under the backdrop of "anti-involution," the supply-demand relationship is expected to continue improving, leading to a potential upturn in product prosperity. Key companies to watch include Wanhua Chemical and Luxi Chemical for their elastic opportunities [3][9][10]. Demand Side Summary - PC and its alloys are widely used in electronics, automotive, and sheet film sectors. Electronics account for 40% of PC downstream applications, while sheet/film and automotive sectors represent 19% and 15%, respectively. Global PC consumption is projected to grow from 4.4 million tons in 2019 to 6.04 million tons by 2024, with a compound annual growth rate (CAGR) of 7%. In China, the apparent consumption of PC is expected to rise from 2.481 million tons in 2021 to 3.61 million tons by 2025, with a CAGR of 10.6% [6][36][38]. Supply Side Summary - As of 2025, global PC capacity is approximately 8.026 million tons per year, with domestic capacity at 4.32 million tons. Chinese companies have made significant technological breakthroughs, leading to a decrease in the industry's concentration ratio (CR5) from 76% in 2018 to 59% in 2025. The domestic capacity growth rate has slowed, with a utilization rate expected to reach 85% by 2025. The import dependency of China's PC industry has decreased from 88% in 2015 to 24% in 2025, with limited new capacity planned for 2026 [7][41][51]. Prosperity Outlook - The majority of companies have completed their integration layouts, and the price difference is expected to widen. Bisphenol A (BPA) is a significant cost component for PC, with the average cost projected at 9,251 RMB per ton in 2025. The price of BPA has decreased significantly from its peak in 2021, and currently, 72% of PC capacity is equipped with BPA facilities. The price of PC has also dropped from nearly 29,000 RMB per ton to around 14,000 RMB per ton. However, since November 2025, the price difference has shown a widening trend, indicating a potential turning point for industry prosperity [8][62][63]. Investment Recommendations - The report suggests focusing on PC-related listed companies, particularly Wanhua Chemical and Luxi Chemical, as the supply-demand dynamics improve and the industry outlook becomes more favorable [9][10].

Logical Analysis - Economic indicators, such as the EuroCoin index, domestic car inventory warning index, and various price and production indices, are used to analyze the market trends of L and PP. For example, a rise in the EuroCoin index is slightly positive for commodities, while a rise in the domestic car inventory warning index is slightly negative for commodities [2]. - The profitability of MTO - made PP, the inventory levels of L and PP, and the production capacity utilization rates are important factors in analyzing the market. For example, an increase in the profitability of MTO - made PP can lead to an increase in production and supply, while changes in inventory levels can affect market prices [4][5]. Trading Strategies - **Single - side trading**: - For the L主力2605 contract, the strategies include holding long positions, setting stop - loss levels, and in some cases, taking a wait - and - see approach. For example, on 26 - 03 - 25, it is recommended to reduce long positions [1]. - For the PP主力2605 contract, similar strategies are adopted, such as holding long positions, setting stop - loss levels, and in some cases, taking a wait - and - see approach [1]. - **Arbitrage trading**: - The SPC L2605&PP2605 contract is used for arbitrage trading. Strategies include holding short positions, setting stop - loss levels, and in some cases, taking a wait - and - see approach [2][5]. - **Options trading**: - In most cases, the reports recommend a wait - and - see approach for options trading [2][5].

1. Report Industry Investment Rating - No relevant content provided 2. Core View of the Report - The domestic plastic futures market is in a complex situation with strong cost support, weak demand, and differentiated inventory. In the short - term, due to the uncertainty of the Middle - East geopolitical situation, the oil price is likely to rise and support the plastic price. With the ongoing domestic device maintenance, the supply is tightening, and the plastic futures price will maintain a strong - side shock. In the long - term, if the geopolitical conflict eases, the cost premium will fade, and the slow recovery of downstream demand and high social inventory will limit the price increase [12]. 3. Summary by Related Catalogs Supply Side - In Q1 2026, the domestic plastic supply showed features of slower capacity expansion, more device maintenance, and a structural decline in the operating rate. The capacity expansion speed slowed down significantly, and there were only a small amount of new production capacity in early January. The industry entered the stage of digesting existing capacity, and the new supply pressure was significantly relieved [3]. - In March, the spring maintenance of domestic petrochemical enterprises led to a contraction in supply. By mid - March, the operating rate of the polyethylene (PE) industry dropped to 82.39%, 4.5 percentage points lower than in February. The weekly output decreased by 37500 tons, and the output affected by device maintenance reached 91000 tons. The profit of coal - based PE was over 1900 yuan/ton, while the oil - based PE was in continuous loss, with a loss of over 2000 yuan/ton, which forced high - cost oil - based capacity to reduce production and conduct maintenance, further intensifying the supply contraction [4]. Demand Side - After the Spring Festival, the downstream plastic product enterprises gradually resumed work, but the resumption rhythm was slower than in previous years. By mid - to late March, the operating rate of the PE downstream agricultural film industry rose to 35.44%, and that of packaging film and pipe industries rose to about 50%. The PP downstream industries had different operating rates, and the overall downstream mainly had rigid demand for procurement. There were two main factors restricting demand: weak terminal consumption and slow export orders, and the high plastic price squeezing downstream profits. However, with the implementation of domestic policies, the demand for some plastic products is expected to improve [6][8][9]. Impact of Geopolitical Situation - The continuous escalation of the Middle - East conflict has become a core external variable affecting oil prices and plastic futures. The shipping volume of the Strait of Hormuz dropped by 92% in March, causing concerns about oil supply disruptions. The oil price rose sharply, and the cost of oil - based plastic increased, driving up the plastic price. But the impact of geopolitics on oil prices is short - term and uncertain [11].
