Report Industry Investment Rating - Not provided in the content Core Viewpoints of the Report - The zinc price will maintain a wide - range oscillation throughout 2026. The price will be relatively strong in the first half of the year due to the structural shortage of domestic raw materials, and the center of gravity may move slightly downward in the second half as the incremental supply is fully transmitted to zinc ingots [1]. - The global zinc mine is entering an expansion cycle (with an expected increase of 290,000 tons), but the domestic market will still be in a tight - balance state in the first half of the year. Driven by the repair of TC, the smelting output will show a trend of "first decreasing and then increasing", with an expected year - on - year growth of over 4.5% for the whole year, and the supply pressure will gradually shift from the mine end to the ingot end [1]. - Although affected by the real estate industry, at the beginning of the "15th Five - Year Plan", infrastructure (UHV, wind power) and high - end manufacturing (new energy vehicle exports) will significantly increase the zinc consumption density, effectively offsetting the decline in real estate. The actual consumption is expected to maintain positive growth and achieve a soft landing [1]. - The core fluctuation range of the SHFE Shanghai zinc main contract in 2026 is predicted to be between 21,500 - 24,800 yuan/ton, and the LME zinc will fluctuate between 2,750 - 3,350 US dollars/ton. In the first half of the year, the domestic market will be stronger than the overseas market, and the price is likely to rise. In the second half, with the arrival of imported ores, the increase in TC will drive smelters to release production. Coupled with the potential drag from the real estate completion end, supply - demand pressure will gradually emerge, and the price center of gravity may decline under pressure [1]. Summary by Relevant Catalog Chapter 2: Market Review - In the first three quarters of 2025, zinc prices fluctuated widely due to repeated macro - expectations and mismatches in industrial supply - demand rhythms. In Q1, the shortage of mines supported the price increase. In Q2, trade frictions and the strong US dollar led to a significant price correction. In Q3, the supply - demand mismatch between domestic and overseas markets led to a resistance - style upward trend with the overseas market stronger than the domestic one [3]. - In Q4, the structural contradiction in the global zinc market reached an extreme. The market shifted from unilateral gambling to cross - market arbitrage. The large gap between domestic and overseas inventories opened the export profit window for Chinese zinc ingots. The export - driven marginal inventory reduction became the core variable affecting price fluctuations, and the market established a pattern of re - balance through exports [5]. Chapter 3: Supply Side 3.1 Zinc Concentrate - In 2025, global zinc mine supply recovered. The annual output is expected to reach 12.51 million tons, a year - on - year increase of 4.6%. In 2026, the output is expected to continue to grow by 2.27% to 12.61 million tons [12]. - Overseas mine production is growing steadily, driven by the resumption of old capacities and the ramping - up of new mines. Key mining enterprises such as Glencore, Ivanhoe Mines, and Teck Resources have good production performance. In 2026, the global new zinc mine increment is about 290,000 tons, and the market will be in a tight - balance state [14][15]. - The overall cost center of global zinc mines has shifted upward. The 90 - percentile line (about $2,400 - $2,550/ton) is considered a long - term "price bottom". If the zinc price falls below this line, about 10% of high - cost mines will face cash - flow losses and trigger passive production cuts [17]. - In 2025, domestic zinc concentrate supply was sufficient in general, but production was affected by environmental and safety inspections at the end of the year. In 2026, new and resumed projects are expected to contribute about 60,000 tons of output (excluding Huoshaoyun). The Huoshaoyun lead - zinc mine needs attention regarding the commissioning of supporting smelters [22]. 3.2 Smelting End - From 2024 to the first half of 2025, the global zinc smelting industry was in a difficult situation due to the extreme shortage of mine supply. In the second half of 2025, with the supplement of imported ores and the increase in TC, domestic smelters' production willingness was positive. The cumulative zinc ingot output from January to October was 5.686 million tons, a year - on - year increase of 10.1%, and the annual output is expected to be 5.9 million tons, a year - on - year increase of 11.5% [35]. - In 2026, the long - term benchmark TC is expected to rise significantly. Domestic smelting capacity can be released with high elasticity, but the supply pressure is expected to be less than that in 2025 [35]. - For overseas smelters, high and volatile energy costs in Europe are a major risk. Other regions such as South Korea, Japan, and Canada are expected to maintain high and stable operating rates. Globally, the refined zinc output is expected to grow by 3% to 14.12 million tons in 2026, indicating a gradual entry into the inventory accumulation cycle [38]. 3.3 Import and Export and Internal - External Price Ratio - In 2025, the zinc import window was mostly in a deep - loss state, especially in the second half of the year. From January to October, China's cumulative refined zinc imports were 2.77 million tons, a year - on - year decrease of 26.6%. The reason is the difference in the fundamentals of domestic and overseas markets, with overseas smelters having difficulty in restoring production due to high costs [39]. - In the future, the repair of the price ratio may be a prerequisite for the reversal of TC. With the increase in overseas mine supply and the resumption of smelter production, the shortage of LME zinc will be alleviated, the premium will decline, the price structure will turn to Contango, and the SHFE - LME price ratio will rise, narrowing the import loss [40][41]. Chapter 4: Demand Side - In 2026, China's refined zinc consumption is expected to show a slight increase of 0.5% - 1.5%, and the demand side is expected to be more resilient than the market's concerns about the drag from the real estate industry, achieving a soft landing [43]. 4.1 Real Estate - In 2025, real estate indicators such as new construction, construction, and completion areas all declined. In 2026, the real estate market will continue to drag down the zinc market. The new construction area is expected to maintain a negative growth of - 10% to - 15%, and the decline in the completion area is expected to narrow significantly to about - 10%. The direct drag on zinc consumption is expected to be about - 2.3% to - 2.7% [47][48]. 4.2 Infrastructure - In 2026, infrastructure investment will benefit from the "15th Five - Year Plan" and is expected to maintain a year - on - year growth of 6.8%. UHV grid construction will be a major highlight, and the demand for high - quality hot - dip galvanized pipes will increase significantly, making the infrastructure sector a key factor in stabilizing the demand base [50]. 4.3 Automobile - In 2025, the Chinese automobile market grew strongly, especially in terms of exports and new energy vehicle penetration. In 2026, although the new energy vehicle purchase tax will be reduced from full exemption to half exemption, the decline in battery costs and price competition among car companies will offset the impact of the policy. The output of new energy vehicles is expected to grow by 22.0%. The high - growth of automobile exports will reshape the zinc consumption structure, as export - oriented vehicles have a higher demand for zinc [52][53][54]. 4.4 Home Appliances - In 2026, the home appliance sector is expected to show a stable growth in zinc consumption, with an expected growth rate of 2.5% - 3.0%. This is mainly due to policy - driven replacement demand, the lagging dividend of real - estate completion, and the increasing demand for anti - corrosion materials in emerging markets [59][60]. 4.5 Photovoltaic and Emerging Fields - In 2026, although the growth rate of new photovoltaic installations is expected to decline to 18.0%, the absolute increment is still high. The penetration rate of Zn - Al - Mg alloy - coated brackets will further increase, and the expansion of application scenarios will ensure that the photovoltaic sector continues to contribute to zinc consumption [69]. 4.6 Downstream High - Frequency Demand Indicators - Various downstream high - frequency demand indicators such as galvanized sheet coil inventory, production, and zinc downstream consumption index show certain seasonal trends, which reflect the real - time demand situation in the zinc market [75][77]. 4.7 Inventory - In the first half of 2025, the inventory was at a historical low, and in the second half, the social inventory began to accumulate, but the accumulation rate was lower than expected. This is mainly due to stronger - than - expected demand, the integration of zinc alloy smelting capacity, and the opening of the export window. In 2026, factors affecting inventory include the recovery of the internal - external price ratio and the increase in overseas smelter production due to the rise in TC [79]. Chapter 5: Supply - Demand Balance Sheet 5.1 Global Zinc Concentrate Balance - In 2026, the global zinc concentrate supply is expected to be 12.6094 million tons, a year - on - year increase of 2.27%, and the demand is expected to be 12.6342 million tons, a year - on - year increase of 2.59%. The market will be in a tight - balance state [81]. 5.2 Global Refined Zinc Balance - In 2026, the global refined zinc output is expected to be 14.1215 million tons, a year - on - year increase of 3.01%, and the consumption is expected to be 13.9837 million tons, a year - on - year increase of 1.49%. The market will turn from a shortage to a surplus [82]. 5.3 China's Refined Zinc Balance - In 2026, China's refined zinc output is expected to be 7.172 million tons, a year - on - year increase of 4.55%. The net import is expected to decrease by 100%. The apparent consumption is expected to be 7.172 million tons, a year - on - year increase of 0.84%, and the actual consumption is expected to be 7.07 million tons, a year - on - year increase of 1.00%. The supply - demand surplus is expected to decrease by 8.92% [83].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In 2026, the price trends of softwood pulp and offset printing paper are expected to be described as "low recovery" and "weak stabilization" respectively. The price center of softwood pulp is expected to move slightly upward, while the price of offset printing paper is expected to remain weak and stable, mainly supported by costs [5]. - Overall, the futures prices of pulp and offset printing paper will fluctuate. In the medium - term, low - buying opportunities can be considered for pulp futures, and high - selling opportunities can be considered for the near - month contracts of offset printing paper [8]. 3. Summary According to the Table of Contents 3.1 Viewpoint Summary 3.1.1 Trend Forecast - In 2026, the supply expansion trend of softwood pulp will slow down, and the demand is expected to stabilize and rebound. However, the market sentiment is limited, and there are still upper limits, with inventory pressure needing continuous attention. The price of double - offset paper is expected to be mainly supported by costs and remain weak and stable [5]. 3.1.2 Strategy Outlook - Pulp and offset printing paper futures prices will fluctuate. Mid - term, consider low - buying for pulp futures and high - selling for near - month offset printing paper contracts [8]. 3.1.3 Risk Points - Risks include changes in macro - policies, significant changes in international trade situations, large - scale shutdowns or resumptions of pulp and paper mills, and restrictions on some supply and transportation channels [9]. 3.2 Market Review 3.2.1 Spot Price Review of Softwood Pulp and Double - Offset Paper - Softwood pulp spot prices declined this year, with a short - term increase in January - February due to domestic supply gaps. After reaching a high of about 6617 yuan/ton in early February, prices dropped by 17.84% by the end of November. Recent slight rebounds are due to traders' reluctance to sell and spot enterprise regulation. The spread between softwood and hardwood pulp prices has fallen to a reasonable range. Double - offset paper prices also declined after a slight increase in Q1, dropping by 13.02% from 5087.5 yuan/ton in mid - March to 4425.0 yuan/ton at the end of November, due to weak demand and over - supply [10][12][16]. 3.2.2 Futures Price Trend Review of Pulp and Offset Printing Paper - Pulp futures reached a high of 6204 yuan/ton in February, then declined, with a temporary halt in the decline in Q3 due to North American pulp mill maintenance expectations. After reaching a low of 4750 yuan/ton in mid - October, prices reversed and rose due to downstream paper mills' price increases, positive macro - sentiment, and news of a US pulp mill shutdown. Offset printing paper futures were listed in September, fluctuated in the first month, rose to 4360 yuan/ton due to paper mills' price support, and then dropped to 3980 yuan/ton, a decline of 8.72% [19]. 3.2.3 Continued Weak Overall Demand - Weak demand is a major factor for the weak pulp and double - offset paper prices. China's softwood pulp monthly apparent consumption in the first 10 months was 707.3 tons, up 2.84% year - on - year, with only 6, 7, 9 months above the average. European consumption of bleached softwood pulp was the lowest in a decade. Paper industry's start - up rates were low, with softwood pulp downstream demand improving slightly but still weak. Double - offset paper demand was even weaker, with the apparent consumption in the first 10 months at 666.7 tons, down 9.87% year - on - year [25]. 3.2.4 Supply Growth Slowed but Pressure Persisted - Pulp supply growth slowed this year, but the overall stock was still high. China's softwood pulp imports had low growth but a high base and increased since August. Paper pulp production increased significantly after mid - September, with a 17.43% year - on - year increase in early December. Global pulp shipments were relatively high, and those to China were lower than in 2023 but higher than last year. Double - offset paper's start - up rate was at a low, but production increased in the second half of the year, and the supply pressure remained due to new capacity [30][32]. 3.2.5 High Inventory and Low Profit - High inventory suppressed pulp and paper prices. China's pulp port inventory was above 200 tons for a long time this year, dropping to 199.3 tons by December 19. Double - offset paper inventory also increased, with both production enterprise and social inventories above the average. Most small and medium - sized enterprises in the softwood pulp and double - offset paper markets were in a loss - making state, with negative gross margins for Chinese softwood pulp since April last year [34][37]. 3.3 Core Focus Points 3.3.1 Macro Changes - Pulp is significantly affected by macro - factors. Interest rate cuts may reduce import costs. Policy changes and tariff adjustments can also impact the industry. For example, if Brazil's export tariff exemption to the US is removed, it may increase China's pulp supply pressure [41]. 3.3.2 Inventory Reduction - High inventory is a key factor suppressing pulp and paper prices. Pulp inventory has declined recently, and the reduction in available registered warehouse receipts due to the adjustment of delivery standards has provided some support to futures prices [42]. 3.3.3 Shutdown/Resumption of Pulp and Paper Mills - Shutdowns or resumptions of pulp and paper mills can affect supply and market sentiment. For example, Domtar's permanent shutdown of the Crofton pulp mill had a positive impact on futures prices [44]. 3.4 Valuation Feedback and Supply - Demand Outlook 3.4.1 Valuation: Relatively Reasonable - Pulp futures valuation is relatively reasonable, with the basis fluctuating and the number of warehouse receipts at a historical low. Offset printing paper futures valuation is currently weak, but the rising basis provides some support at the bottom. The volatility of both pulp and offset printing paper futures is expected to remain low in 2026 [45][47][50]. 3.4.2 Demand: Weak Stabilization - Pulp demand is expected to stabilize and rebound in 2026, with the "14th Five - Year Plan" promoting economic growth and the narrowing price spread between softwood and hardwood pulp potentially increasing softwood pulp demand. Double - offset paper demand is expected to be weak, with factors such as the decline in textbook demand and the popularity of paperless office, but policies like the "National Reading Promotion Regulations" may bring some positive effects [52][57]. 3.4.3 Supply: Pressure Converging - In 2026, the supply pressure of softwood pulp is expected to converge, with limited new capacity growth. Double - offset paper supply pressure remains due to continuous new capacity investment in recent years. Overall, the supply - demand situation of softwood pulp in 2026 is expected to be slightly better than this year, while double - offset paper supply and demand are expected to remain weak and stable [59][61][63].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - In 2026, the polyester production growth rate is expected to gradually slow down, but the demand growth rate is still estimated to reach around 4.5%, maintaining resilience. The terminal weaving orders have declined comprehensively, and the demand negative feedback will gradually spread upstream. The polyester load is expected to decline from late December, with the monthly average polyester load in January - March estimated at 89%, 84%, and 89.5% respectively. In the off - season, the demand side is difficult to drive prices upward [1]. - For MEG in 2026, the main trend will return to a pattern of oscillating and bottom - grinding. With the successive launch of new production capacities, high - level operation and high valuation are difficult to maintain. After the inventory accumulation expectation, the valuation has been rapidly compressed. Although the static supply - demand balance has improved, the cost side may bring additional negative factors. The over - supply expectation will continue to suppress the valuation to clear marginal production capacities, and the "reversal" may depend on macro - narrative drivers [1][19]. - PTA's production cut since the fourth quarter of 2025 has exceeded market expectations, alleviating the PX - TA structural contradiction. In 2026, there are plans to launch two PX production facilities with a total capacity of 5 million tons, expected to be put into operation after the third quarter, while PTA is not expected to have new capacity launches. In the first half of 2026, PTA's supply is expected to be tight against downstream demand, but the final inventory reduction depends on PTA's production cut intensity. PX's supply - demand pattern is favorable, and it is expected to be prone to rising and difficult to fall. However, before the upward driver appears, there may be a phased correction [2][26]. 3. Summary According to Relevant Catalogs 3.1 Chapter 2: Market Review 3.1.1 MEG Market Review - In Q1 2025, MEG prices dropped significantly due to cost collapse and weakening supply - demand patterns. In January, prices oscillated at a high level; in February, they rebounded slightly and then fell; in March, they were in low - level consolidation [3]. - In Q2 2025, macro and geopolitical factors dominated. The price once hit a low of 3956 yuan/ton and then rebounded. The geopolitical events in June led to price fluctuations [4]. - In Q3 2025, the "anti - involution" sentiment affected prices. The price reached a high of 4580 yuan/ton and then oscillated [4]. - In Q4 2025, MEG's valuation was continuously compressed with inventory accumulation and weak cost, and the price showed an oscillating downward trend [4][5]. 3.1.2 PTA Market Review - In Q1 2025, PTA prices mainly fluctuated with the cost, oscillating between 4700 - 5350 yuan/ton [8]. - In Q2 2025, macro and geopolitical factors dominated. The price once dropped to 4016 yuan/ton and then rebounded [9]. - In Q3 2025, PTA prices oscillated widely between 4500 - 5000 yuan/ton under the influence of cost and macro factors [10]. - In Q4 2025, PTA prices lacked a core driver after a rebound, oscillating narrowly between 4550 - 4800 yuan/ton [11]. 3.2 Chapter 3: Core Focus Points 3.2.1 MEG - In 2026, MEG will be in an oscillating and bottom - grinding pattern. The short - term weak pattern will continue, with port inventory expected to reach over 1.1 million tons in Q1 2026. The demand negative feedback will spread upstream, and the cost side remains weak [19][20]. - The "anti - involution" as a macro - mainline trading focus may repeatedly dominate the commodity market. The risk points for upward rebound mainly include unexpected reduction in large - scale production facilities, macro - policy benefits, and significant cost increase [23]. 3.2.2 PTA - PTA's production cut since Q4 2025 has alleviated the PX - TA structural contradiction. In 2026, PX has new capacity launch plans, while PTA has none. In H1 2026, PTA supply is tight against downstream demand, and PX is expected to be in a favorable supply - demand pattern, prone to rising and difficult to fall [2][26]. - In the near - term, the negative feedback from the terminal will spread upstream, and PX's valuation may correct. In the long - term, PX is expected to maintain an upward - prone pattern, and PTA's processing fee may be further repaired, but the supply - benefit dynamic balance will be the long - term main logic [28][29]. 3.3 Chapter 4: MEG Industry Analysis 3.3.1 MEG Industry Pattern Analysis - China's MEG production capacity has increased rapidly in recent years, changing from supply shortage to over - supply. In 2025, new capacity launches led to inventory accumulation expectations and a decline in valuation [33]. - Currently, the total MEG production capacity in the Chinese mainland is 30.275 million tons, with ethylene - based capacity accounting for 63% and coal - based capacity accounting for 37%. The production efficiency of coal - based MEG has improved, but it is expected to face pressure in 2026 [33][34]. 3.3.2 MEG Supply Analysis - In 2025, China's MEG production increased mainly due to the increase in operating rates. However, after the launch of new capacity in September, the valuation was under pressure, and the production profit of coal - based MEG was compressed in Q4 [36]. - In terms of product switching, some enterprises switched production between EO and EG based on production efficiency. In 2026, under the background of loose supply - demand, the MEG load is expected to decrease year - on - year [37]. - In 2025, the MEG import volume increased year - on - year, and the import source concentration increased. If India's anti - dumping policy is implemented, the global MEG logistics pattern may be reconstructed [48][49]. 3.3.3 MEG Balance Sheet Analysis - In Q1 2026, MEG is expected to have a slight over - supply, with an estimated cumulative over - supply of about 350,000 tons. In Q2, if the maintenance plans are implemented as scheduled and the polyester demand is in the peak season, there may be a supply - demand gap of about 300,000 tons. The annual demand growth rate is estimated at around 4.5% [57]. 3.4 Chapter 5: PTA Valuation Feedback and Supply - Demand Outlook 3.4.1 PX - PTA Industry Pattern Analysis - China's PX production capacity expansion has paused since 2024, while PTA has maintained a high - speed growth trend. The PX supply - demand pattern is relatively tight, while PTA has an over - supply problem, and the clearing of backward production capacities and the increase in exports are the main focuses for improving the supply - demand structure [59]. 3.4.2 PTA Supply Analysis and Valuation Feedback - In 2025, PTA's processing fee showed significant fluctuations. In Q4, due to production cuts, the processing fee was repaired, but in the long - term, it is expected to remain under pressure. In 2026, the supply - benefit dynamic balance is expected to be maintained, and the processing fee's upward space is limited [63][64]. 3.4.3 PTA Export Demand Analysis - In 2025, PTA exports decreased year - on - year, mainly due to the new production capacity in Turkey. The export reduction was partially transferred to other countries [67]. 3.4.4 PTA Balance Sheet Analysis - In 2026, the polyester load is expected to decline seasonally. In Q1, PTA is expected to have a slight over - supply of 100,000 - 150,000 tons, and in Q2, there will be a large supply - demand gap. The actual inventory reduction depends on the restart plans of PTA production facilities [74][75]. 3.5 Chapter 6: Polyester Demand Analysis 3.5.1 Start - up Performance - In 2025, polyester production increased by 7.4% year - on - year, and the production capacity growth rate slowed down. Currently, the terminal orders have declined, and the polyester demand load is expected to decline from late December. In Q1 2026, the polyester load is estimated at 89%, 84%, and 89.5% in January - March respectively [77]. 3.5.2 Macro - demand - In 2025, China's social consumer goods retail sales increased by 4% year - on - year, while textile and clothing consumption maintained a low - speed growth. The export demand was affected by international situations, with the growth rate decreasing in the second half of the year [98][103].

南华期货玻璃纯碱产业周报 ——低位震荡，等待为主 寿佳露（投资咨询资格证号：Z0020569） 交易咨询业务资格：证监许可【2011】1290号 2025年12月21日 第一章 核心矛盾及策略建议 1.1 核心矛盾 当前影响玻璃纯碱走势的核心矛盾有以下几点： * 远端交易预期 1、观察玻璃冷修预期（春节前）进一步兑现的程度。前期盘面下跌后，部分产线冷修预期被强化，影响市场 预期和远月供需逻辑。另一方面，玻璃冷修将影响纯碱刚需。 2、成本逻辑。玻璃产线煤改气或者石油焦改气均会抬升产业链成本；纯碱除了煤，原盐价格也需要关注。 1、12月-春节前仍有部分玻璃产线冷修等待兑现，或影响远月定价和市场预期。此外，政策对供应的扰动尚 不能排除，关注明年供应预期的变化。 2、近月01仍将跟随现实（交割逻辑），仓单博弈为主。纯碱则以成本定价为主，虽然供应端偶有降负，但新 产能待投，产量也仍在中高位置，没有趋势性减产的情况下纯碱估值难以有向上弹性，且随着玻璃冷修预期 再起，纯碱刚需有下滑的预期。 3、现实层面，无论供应预期如何变化，目前玻璃中游的高库存需要被消化；至于纯碱，新产能已经上路，尚 无法脱离供需过剩的一致预期。 ∗ 近 ...
