Core Viewpoint - The chemical industry, particularly the polyurethane sector, is experiencing a price increase led by Wanhua Chemical, but a full recovery is still distant due to ongoing challenges in downstream demand and supply chain issues [1][8]. Price Increase Dynamics - Wanhua Chemical has initiated multiple price hikes for its core products, including MDI and TDI, starting from December 2025, following similar moves by global giants like BASF and Dow [1][2]. - The price adjustments include a $200/ton increase for MDI in Southeast Asia and South Asia, and a €300/ton increase for all MDI products in Europe [2][3]. - The price surge is attributed to unexpected production halts and geopolitical factors affecting raw material costs, alongside seasonal maintenance peaks [3][5]. Supply Chain Challenges - Significant production disruptions have occurred, including a one-month shutdown of Hunstman’s MDI facility in the Netherlands and maintenance at Wanhua's 1 million ton/year MDI plant in Ningbo [4][5]. - The ongoing structural shortage of ethylene in Europe and Asia is a critical concern, exacerbated by the permanent closure of several ethylene cracking facilities by major companies [6][7]. Industry Outlook - The chemical industry in Europe faces long-term challenges due to energy structure issues and stringent carbon emission policies, which may weaken its international competitiveness [7]. - Despite the supply issues in Europe and Japan, a complete recovery of the industry hinges on the rebound of downstream demand [8][9]. - Wanhua Chemical's financial performance shows signs of stabilization, with a slight increase in net profit in Q3 2025, although overall revenue remains down year-on-year [11].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The current spot price of caustic soda is stable with a slight decline. The supply side is operating at a high level, and the demand side shows weakening trends. The overall supply - demand situation is weak. The future focus is on changes in liquid chlorine prices, device dynamics, and the implementation of macro anti - involution details [3]. - The PVC market was weak in the early part of the month, rebounded due to macro - sentiment, and then the macro - sentiment faded, with the overall supply - demand situation remaining weak. It is expected to fluctuate in the near future, and attention should be paid to subsequent device maintenance and macro - side policies [6]. 3. Summary According to the Directory 3.1 Basis Strategy Analysis - **Caustic Soda**: The basis of caustic soda maintains a C - structure. The spot price first fell, then rose, and then fell again. The inventory is at a high level, and the basis is expected to continue to weaken. A reverse cash - and - carry strategy is recommended [12]. - **PVC**: The basis of PVC also shows a C - structure. After the price hit a new low, the supply - demand situation improved marginally, and the basis strengthened slightly. However, it is expected to weaken again in the future, and a reverse cash - and - carry strategy is recommended [12]. 3.2 Caustic Soda Price & Spread - In December, the spot price of caustic soda first fell, then rose, and then fell again. The high - level operation of production led to an oversupply situation and inventory accumulation. The demand from alumina is relatively stable, but the procurement price has been adjusted downward. Non - aluminum downstream demand enters the off - season in January [13]. 3.3 PVC Price & Spread - In December, the PVC price first fell and then rose. The high inventory led to a continuous decline in price, and the low price improved the supply - demand situation marginally. Macro - sentiment boosted the long - term demand expectation, but the overall supply - demand situation remained weak after the macro - sentiment faded [35]. 3.4 Cost and Profit - The comprehensive profit of chlor - alkali has been significantly reduced and is at a low level compared to the same period. The profit of PVC upstream raw materials is extremely compressed. The price of ethylene is expected to remain weak in January [52]. 3.5 Caustic Soda Supply - In December, new caustic soda production capacity was put into operation, and the overall supply remained at a high level. There are few planned maintenance enterprises in January, and the supply is expected to remain high due to the good market conditions of liquid chlorine [70]. 3.6 Liquid Chlorine Price and Its Downstream Products - In December, the price of liquid chlorine increased. The downstream demand supported the price, but in January, the terminal demand of some downstream products entered the off - season, and the price is expected to fluctuate slightly [82]. 3.7 PVC Supply - The overall PVC output remained high in December. All new production capacity has been put into operation, and the supply is still abundant. There is no new domestic production capacity in 2026, and the overseas supply contraction in December 2025 provided a small support to the market sentiment [98]. 3.8 Caustic Soda Downstream Demand - The demand from alumina is expected to weaken in the long - term. The non - aluminum downstream demand enters the off - season in January, and the demand of various industries is expected to decline seasonally [110]. 3.9 Caustic Soda Import and Export - The main import sources of domestic liquid caustic soda in November were Singapore, Norway, and Germany, and the main export destinations were Indonesia, Australia, and Canada. The export orders remain normal [132]. 3.10 PVC Downstream Demand - The downstream demand for PVC is weakening. The demand for pipes and profiles is affected by the sluggish real - estate market, while the film industry performs relatively well. The downstream demand is expected to decline further in January [145]. 3.11 PVC Import and Export - The BIS certification and anti - dumping duties of PVC in India have been cancelled, and the export expectation for 2026 is improving. The current PVC export maintains its resilience through price - for - volume strategy [156]. 3.12 Caustic Soda and PVC Inventory Data - The inventory of caustic soda increased in December due to factors such as production increase and weakening downstream demand. The PVC social inventory continued to increase, and the high - level futures warehouse receipts continued to suppress the PVC futures price [160].

1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report - The short - term central price of synthetic rubber will move up, and it will enter a volatile phase in the medium term [2][4]. - The short - term price of butadiene is expected to be bullish, but it still faces high supply pressure in the medium term [7]. 3. Summary by Related Catalogs 3.1 This Week's Synthetic Rubber View Supply - In January 2026, China's expected output of cis - butadiene rubber is 153,700 tons, an increase of 10,100 tons compared to the expected output in December 2025. One set of equipment with an annual processing capacity of 100,000 tons/year is planned for maintenance in the next month. The only established maintenance plan is for Maoming Petrochemical, and some other equipment maintenance plans may be cancelled. Dushanzi Petrochemical's 30,000 - ton high - cis cis - butadiene rubber plant is planned to be shut down throughout 2026 [4]. - The static valuation range of the cis - butadiene rubber futures is 10,700 - 11,700 yuan/ton. Due to the strong expectations of butadiene in futures trading, the futures price is at a premium to the spot price, and the upper limit of the static valuation is invalid. The valuation logic has switched, with the NR - BR spread supporting the lower valuation instead of the cost side [4]. Demand - In terms of rigid demand, the capacity utilization rate of tire sample enterprises is expected to continue to be weak from December 26, 2025 to January 1, 2026. Some enterprises arranged routine maintenance during the New Year's Day holiday, and production scheduling at the end of the month decreased. Some enterprises continued to control production, resulting in a slight decline in the overall capacity utilization rate [6]. - In terms of substitution demand, the spread between the NR - BR main contracts remains high, so the substitution demand remains high. Overall, the demand side of cis - butadiene rubber maintains a high year - on - year growth rate [6]. Inventory - As of December 31, 2025, the domestic inventory of cis - butadiene rubber was 33,500 tons, a decrease of 1,000 tons compared to the previous period, a month - on - month decrease of 3.07%. The price of cis - butadiene rubber increased due to cost support. The bullish mid - term market outlook in January boosted the enthusiasm of some traders, and with the impact of a small amount of stockpiling before the New Year's Day holiday, some production enterprises significantly destocked, while the inventory of sample trading enterprises increased [6]. Strategy - Unilateral: The short - term trading range will move up. The upper pressure is 11,700 - 11,800 yuan/ton (moving up dynamically following the spot price of cis - butadiene rubber), and the lower support is 10,700 - 10,800 yuan/ton (supported by the NR - BR spread and butadiene cost) [5]. - Cross - variety: The NR - BR spread will gradually narrow [5]. 3.2 This Week's Butadiene View Supply - From December 19 to 25, 2025, the estimated weekly output of Chinese butadiene sample enterprises was 112,500 tons, an increase of 100 tons compared to the previous period, a month - on - month increase of 0.09%. The weekly output in the next week is expected to be about 113,400 tons, mainly due to the resumption of production at Dongming Petrochemical [7]. Demand - In the medium term, the operating rates of cis - butadiene rubber and styrene - butadiene rubber remain high, so the demand for butadiene maintains a high year - on - year level. In the short term, as the maintenance of cis - butadiene rubber plants decreases, the rigid demand for butadiene from synthetic rubber is expected to remain high [9]. - ABS has high inventory pressure, and its demand for butadiene is expected to remain at a constant level with limited incremental demand [9]. - The operating rate of SBS has slightly increased, and it maintains rigid demand for butadiene with little change [9]. Inventory - From December 25 to 31, 2025, the domestic butadiene inventory fluctuated slightly, with the total sample inventory decreasing by 0.13% compared to the previous week. The inventory of sample enterprises decreased by 4.58% compared to the previous week, while the port inventory increased by 3.23% compared to the previous week. Traders expect imports to decrease in January [9]. 3.3 Butadiene Fundamental Analysis - Butadiene is currently in the supply - demand pricing stage and has a low correlation with the raw material end [12]. - To meet the expansion of downstream industries such as ABS, SBS, styrene - butadiene, and cis - butadiene, the butadiene industry is in a state of continuous expansion, and its expansion speed and amplitude are slightly faster than those of downstream industries at certain stages [14][16]. 3.4 Synthetic Rubber Fundamental Analysis Cis - Butadiene Rubber Supply - The output and operating rate data of cis - butadiene rubber show certain fluctuations over the years [47]. - The cost, profit, and gross margin of cis - butadiene rubber production also fluctuate over time [49][50][51]. - The import and export volume of cis - butadiene rubber shows different trends over the years. The weekly apparent demand also fluctuates [53][54][55]. - The inventory of cis - butadiene rubber, including enterprise inventory, futures inventory, and trader inventory, shows different trends over time [59][61]. Cis - Butadiene Rubber Demand - The inventory and operating rate of tires, an important downstream product of cis - butadiene rubber, also show different trends over the years [63][64].
