Investment Rating - The report assigns a "Buy-A" rating for the chemical industry, indicating a positive outlook for investment opportunities in this sector [1]. Core Insights - The chemical industry is currently at the bottom of a four-year down cycle, with multiple indicators suggesting it has nearly bottomed out. The year 2026 is anticipated to be a turning point for the cycle [2]. - The China Chemical Product Price Index (CCPI) was reported at 3930 points on December 31, 2025, a 39% decrease from the peak in 2021, indicating the industry is in a historically low range [2]. - The basic chemical sector achieved a net profit of 112.7 billion yuan in the first three quarters of 2025, reflecting a year-on-year increase of 7.5%, suggesting initial stabilization [2]. - Capital expenditure in the industry has decreased by 18.3% year-on-year, marking seven consecutive quarters of negative growth since Q4 2023, indicating the end of the supply expansion phase [2]. Summary by Sections Chemical Cycle Turning Point - The report confirms the turning point of the chemical capacity cycle, with indicators showing that the industry is at the bottom of a down cycle and is expected to recover in 2026 [12]. - The capital expenditure to revenue ratio and the ratio of construction projects to fixed assets are both declining, further indicating the end of the supply expansion phase [12][10]. Changing Landscape of the Chemical Industry - The chemical landscape is shifting from West to East, with European chemical companies facing high energy costs and regulatory pressures leading to capacity reductions. For instance, Europe has shut down 11 million tons of ethylene capacity, nearly 10% of its total capacity [3]. - In contrast, Chinese companies are rapidly gaining market share due to their scale and cost advantages, with 60% of monitored chemical products showing high export volumes [3][20]. Upstream Resource Value Reassessment - The report highlights three categories of assets to focus on: cyclical assets (e.g., phosphorus, sulfur, chromium), value assets (e.g., potassium, titanium), and dividend assets (e.g., crude oil) [3][7]. - Phosphorus and sulfur are expected to see sustained demand due to their strategic importance in new energy and battery technologies [3]. New Cycle Observations - The report discusses the proactive and reactive measures in the industry to combat "involution," suggesting that sectors with high concentration and low profitability are more likely to see effective self-regulation [5][7]. - The focus on new productive forces is emphasized, with significant investment opportunities in green energy, advanced manufacturing, and consumption upgrades [6][7]. Key Companies to Watch - The report identifies several leading companies in the chemical sector that are positioned favorably due to their cost advantages and market positioning, including Wanhua Chemical, Hualu Hengsheng, and others [7][50].

MDI Market Overview and Outlook Industry Overview - The global MDI market is currently experiencing a supply-demand imbalance, primarily due to new capacities from China and South Korea, coupled with the impact of US-China tariffs, which limit price increase momentum. The domestic market has entered a low season, and short-term prices are expected to remain stable [1][2] - Global MDI demand growth is lower than expected but still positive. Recent domestic prices for polymer MDI are around 14,500-14,600 RMB/ton, while pure MDI has decreased to approximately 19,500 RMB/ton [1][2] Key Points and Arguments - **Price Dynamics**: The MDI industry has seen significant changes in 2025, with slow recovery in domestic and overseas demand. The expected global demand growth was initially set at 3-4%, with domestic expectations at 5-6%, but actual growth has fallen short [2][5] - **Regional Price Comparison**: Recent price adjustments in Asia were lower than anticipated, with a recent increase of $100 instead of the expected $200. Current prices in Europe and domestically are close, while the US market remains stable due to anti-dumping policies and stable demand [2][3] - **Production Rates**: Domestic MDI operating rates have dropped to around 70%, with planned maintenance by companies like Wanhua Ningbo and BASF Chongqing having limited supply impact. European operating rates are also around 70%, while US production has returned to normal levels [4][6] - **Demand Drivers**: Domestic demand for MDI is positively influenced by growth in refrigerator and freezer production, automotive production, and cold storage capacity. The demand for formaldehyde-free board materials is increasing, and wind turbine blade demand is also growing [5][7] Additional Important Insights - **Inventory Levels**: MDI inventory is distributed among factories, traders, and end customers. Factory inventories are normal, while traders are keen to stock up, and downstream customers are maintaining low inventory levels due to seasonal price fluctuations [11] - **Future Demand Outlook**: The outlook for 2026 is optimistic, with reduced tariff impacts and recovery in the refrigerator and freezer supply chain. The automotive sector is expected to maintain high growth, although slightly lower than in 2025. Exports may rebound, particularly from Europe, Africa, and India, compensating for weakness in the US market [9][10] - **Cost Structures**: Domestic production costs vary, with Wanhua using a coal chemical route at a lower cost compared to others using natural gas. European production costs are higher due to stable natural gas prices, while US production costs remain the lowest globally [13][15] Conclusion - The MDI market is navigating through a complex landscape of supply-demand dynamics, pricing pressures, and regional variations. The outlook for 2026 appears positive, with several growth drivers in place, although challenges remain in the form of geopolitical tensions and market fluctuations.

万华化学：公司为全球MDI行业的龙头，国内及亚太地区最大的MDI制造企业，拥有380万吨MDI产 能；公司此前宣布将从12月1日起，上调在东南亚及南亚地区的聚合MDI与纯MDI产品价格，调涨幅度 为200美元/吨。 据生意社12月3日消息，匈牙利宝思德公司宣布1日起对所有MDI产品涨价，涨幅均为300欧元/吨（约 2400人民币）。 消息面上，据慧正资讯，亨斯迈位于荷兰罗曾堡的28万吨/年MDI装置于11月21日前后意外停车检修， 预计停产将持续至少一个月，其另一套16万吨/年装置也同步降至低负荷运行。此外，近期MDI行业进 入密集检修期，在供应收缩预期推动下，国际巨头巴斯夫、万华化学相继提价。 东方证券表示，从下半年的MDI行情来看，纯MDI由于供需更集中于国内，且保质期短难以库存，在下 游氨纶等需求并不旺盛的情况下，价格已经回到去年年末的高点。虽然当下并不是MDI需求的旺季，但 供给端的意外收缩，有望催动MDI价格反弹。而且MDI供给格局与需求情况更好于TDI，不排除本次事 件成为行业中长期拐点的可能。 公司方面，据上市公司互动平台表示， 氯碱化工：公司参股30%上海亨斯迈聚氨酯和15%上海联恒:上海亨斯 ...
