1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - In March, the trading mainline of the caustic soda market switched, and the price shifted from "low - level repair" to "central - level upward movement", which was the result of the superposition of sentiment, flow, and marginal fundamental repair [2][3] - In April, the caustic soda price is more likely to operate in a "high - level volatile and strong" manner rather than a "unilateral continuous short - squeeze". The price center is expected to rise compared with February, but further upward movement requires continuous inventory decline and actual export orders [17][18] 3. Summary by Directory 3.1 Market Review - In March, the trading mainline of the caustic soda market changed. In February, the core contradiction was high - start, high - inventory, and unconfirmed post - holiday demand recovery, with prices showing low - level stability and basis repair. In March, geopolitical disturbances, improved foreign inquiries, marginal decline in domestic factory inventories, and stable alumina demand drove the price to move upward [2][3] - From late February to March 26, the national 32% liquid caustic soda price rose from 634 yuan/ton to 728 yuan/ton, a 15% increase. The caustic soda price increase was in the context of the overall valuation increase of the energy and petrochemical chain [3] - The caustic soda main contract rose from 2125 yuan/ton at the end of February to 2442 yuan/ton on March 9 and 2547 yuan/ton on March 16, then fluctuated, with a maximum of 2675 yuan/ton, and closed at around 2500 yuan/ton on March 26. The weekly average price of Shandong 32% caustic soda was 716 yuan/ton, a 14% increase from the previous month [4] - The core of the trading logic in March was the superposition of "export expectation + energy cost expectation + high - level sentiment". The continuation of the market depends on export order fulfillment, inventory decline, and stable alumina procurement [4] - In early March, the main driver was external shocks. After the escalation of the Middle East geopolitical conflict, the supply expectations of global natural gas and olefin chains tightened, and the export expectation of high - concentration caustic soda increased [5] - After mid - March, the market transitioned from "pure expectation - driven" to "real - data verification". Whether the price could stabilize depended on factors such as whether factory inventories peaked and declined, whether alumina procurement remained stable, and whether the spot market could follow the upward movement of the futures [6] 3.2 Fundamentals 3.2.1 Supply - The high - start pattern continued in March, and the supply pressure was marginally relieved. The industry average start - up rate remained at a high level, with about 86.1% in February, around 86.4% in the first week of March, and 84.6% this week. The national chlor - alkali load is expected to recover to around 85% next week [8] - The liquid caustic soda factory inventory increased from 50.96 million tons at the end of February to 55.57 million tons in the first week of March and 52.54 million tons this week, a 4.93% increase month - on - month. The de - stocking needs to be verified [8] - In April, the focus of the market on supply is whether high - start can coexist with de - stocking [9] 3.2.2 Demand - Alumina is the core of total demand, and non - aluminum demand determines marginal elasticity. In March, the alumina start - up rate remained at around 81.8%, and non - aluminum downstream industries improved slightly compared with February, but the overall increase was limited [10] - The key to whether the caustic soda price has continuous support lies in the stability of the alumina demand base and whether non - aluminum demand repair can drive de - stocking [10] 3.2.3 Inventory and Flow - The core of the inventory logic in March was that the inventory direction changed from "continuous accumulation" to "loosening at a high level". The inventory decreased after rising in March, indicating an improvement in the spot acceptance ability [11] - The linkage of inventory, export inquiries, and basis is the key to track. For April, the inventory path is the first indicator to judge the market nature [11] 3.2.4 Cost and Profit - The core cost components are electricity (55% - 65% of the total cost, with a power consumption of 2900 - 3100 degrees per ton of caustic soda), raw salt (10% - 15%), and processing and others (about 20%) [12] - In March, the industrial electricity price in main production areas such as Shandong decreased, and the self - supplied power in the northwest had significant advantages. The raw salt price was stable with a slight increase. The full cost in Shandong was about 1800 - 2050 yuan/ton, and the marginal cost was 2300 - 2600 yuan/ton, forming a price bottom [13] - There were regional differences in profits. The profit of self - supplied power + integration in the northwest was 2140 yuan/ton, the comprehensive profit of chlor - alkali in Shandong was 550 yuan/ton, and the profit of single caustic soda enterprises was only 100 - 500 yuan/ton. The increase in liquid chlorine price improved the profit, but the weakening of PVC dragged down the comprehensive profit [13] 3.3 Foreign Trade and International Pricing - In March, the marginal impact of external factors on caustic soda increased. The FOB export inquiry price of caustic soda in East China rose to 340 - 450 US dollars/ton on March 12, higher than the previous transaction range of Northeast Asian liquid caustic soda [16] - The export logic is in the stage of "enhanced expectation, to be tracked for fulfillment". In April, in addition to external events, it is necessary to track whether the foreign quotation remains strong and whether the domestic spot pressure is reduced due to export diversion [16] 3.4 March Outlook and Futures Strategy - In April, caustic soda is more likely to operate in a "high - level volatile and strong" manner. The supporting factors include the increase in the official monitoring price of 32% liquid caustic soda, the marginal decline of factory inventory after mid - March, stable alumina demand, and strong export inquiries [17] - The suppressing factors include the high - start pattern of the industry, high absolute inventory level, and the high proportion of sentiment and geopolitical factors in the March price increase [18] - Key variables to track include the prices of 32%/50% liquid caustic soda, the path of sample factory inventory, the operating load of alumina, and the changes in FOB export inquiries in East China. Industrial customers are more suitable for rolling hedging [18]

Report Summary 1) Reported Industry Investment Rating - The trend strength of caustic soda is 0, indicating a neutral view [3]. 2) Core View of the Report - Macro anti - involution sentiment and capital position transfer drive a short - term rebound in caustic soda, but fundamentally, it remains in a pattern of high production and high inventory. The demand side has limited support, and the supply side has large pressure, with the product facing price - cut and inventory - reduction pressure before the Spring Festival. The valuation of caustic soda is always suppressed by the alumina production - cut expectation, and without production cuts by manufacturers, a significant rebound is difficult [2]. 3) Summary by Relevant Catalogs Fundamental Tracking - The 01 - contract futures price is 2181. The cheapest deliverable 32% caustic soda spot price in Shandong is 710, and the Shandong spot 32% caustic soda converted to the futures price is 2219, with a basis of 38 [1]. Spot News - On December 22, the local price of liquid caustic soda in Shandong was stable, and individual enterprises slightly adjusted prices according to their own shipment conditions [1]. Market Condition Analysis - The demand side: Low alumina profits lead to negative feedback in the caustic soda industry chain. Non - aluminum downstream industries face seasonal declines in rigid demand, and exports are under pressure, so overall demand has limited support. - The supply side: Winter is the off - season for chlor - alkali enterprise maintenance. With high operating rates, there is a large supply pressure of caustic soda, and enterprises face high - inventory pressure. Caustic soda inventories increased this week, and there is still pressure to cut prices to reduce inventory before the Spring Festival [2].
