5.9纯碱日评:纯碱市场整体企稳,个别区域小幅回落
Sou Hu Cai Jing· 2025-05-10 03:50
Group 1 - The overall domestic soda ash market remains stable, with slight declines in some regions. Prices for light soda ash in East China are between 1340-1530 CNY/ton, while heavy soda ash prices range from 1420-1500 CNY/ton [2] - Supply side shows an increasing number of manufacturers undergoing maintenance and production cuts, leading to a decrease in industry operating rates, with expectations of further supply contraction in the future [2][5] - Demand is weak as downstream companies are not performing well, leading to low purchasing enthusiasm. Most companies prioritize digesting existing inventory, resulting in market transactions primarily consisting of small orders and low-price deals [2][5] Group 2 - On May 9, the main contract for soda ash (SA2509) opened at 1318 CNY/ton and closed at 1305 CNY/ton, with an intraday decline of 0.38%. The highest price during the day was 1329 CNY/ton, and the lowest was 1300 CNY/ton, with total open interest at 1,221,435 contracts, an increase of 17,878 contracts [3] - The decline in soda ash futures prices is primarily driven by overall market sentiment and significant drops in downstream products. The fundamental situation for soda ash has not shown notable improvement, and while some supply-side maintenance has begun, it is insufficient to reverse the oversupply situation [3][5] Group 3 - The supply contraction trend is becoming more evident, and although demand is generally weak, some essential purchases are starting to emerge as inventory is gradually digested, providing some support to the market [5] - It is expected that short-term market prices will remain stable, with the possibility of slight increases in regions with relatively tight supply-demand structures. Future attention should be paid to the execution of new maintenance plans and changes in actual downstream purchasing rhythms [5]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For the soda ash market, the industry conference promotes production - cut and price - support plans. Although short - term factory inventory is expected to decrease and the mid - stream may stop reducing inventory, continuous price increases are difficult. The long - term bearish trend remains, but caution is needed before the positive feedback atmosphere ends. Traders are advised to pay attention to new order transaction prices and the implementation of maintenance and price - support plans, and short - term short - covering and then short - selling at high prices are recommended after the upward sentiment calms down [8][9]. - For the glass market, from a valuation perspective, it has entered an ideal layout range, but it is necessary to wait for the market sentiment to improve. A long - position strategy for far - month contracts is recommended, and subsequent attention should be paid to production line changes, the digestion progress of low - price spot and futures sources, and the price - volume sentiment changes of spot in major production areas [173]. 3. Summary by Directory 3.1 Soda Ash Market Review - **Supply**: The total weekly production is 75.51 million tons, with heavy - soda production at 41.55 million tons and light - soda production at 33.96 million tons. The import volume is 0.07 million tons, and the export volume is 4.2 million tons. There are production - cut and maintenance plans in the industry, and potential incremental production awaits the full - capacity operation of Jiangsu Debang and the subsequent commissioning of Lianyungang Alkali Plant [8]. - **Demand**: The heavy - soda consumption is 34.27 million tons, and the light - soda apparent demand is 30.87 million tons. The apparent demand for soda ash is 77.54 million tons. The market's expectation for terminal demand is weak, but the short - term apparent demand may be boosted by the positive feedback between futures and spot [8]. - **Inventory**: The alkali factory inventory is 169.1 million tons, and the social inventory is 33.85 million tons. With the positive feedback and subsequent production - cut expectations, short - term factory inventory is expected to decrease, while mid - stream inventory may stop falling and start to rise [8]. - **Valuation**: The ammonia - soda process cost is 1327 yuan, and the profit is 83 yuan. The combined - soda process cost is 1170 yuan, and the profit is 140 yuan.
