Spot Market - The report presents the domestic soda ash price summary table on July 23, 2025, showing price changes compared to July 22, 2025 [6] 4. Influencing Factors 4.1 Policy - related - Policy expectations such as the steady - growth plan for the building materials industry and the "city - specific policies" in the real estate sector, combined with low inventory, have driven market sentiment up [7] 4.2 Fundamental Analysis - Supply side: The weekly output was 568,800 tons, a month - on - month increase of 0.61%. However, summer maintenance led to supply contraction, and the release progress of new capacity from Yuanxing was slower than expected. - Demand side: The daily melting volume of float glass was 168,000 tons, a month - on - month increase of 0.76%, and the rigid demand for heavy soda ash procurement increased [8] 4.3 Technical Analysis - The price of the Soda Ash 2509 (SA509) contract deviated from the 5 - day moving average today, and there may be a need for technical repair. However, the trend indicator still maintained a bullish signal, indicating that the short - term trend is still upward, but the repair demand may cause the price to pull back to some extent [9] 5. Market Outlook - The current soda ash futures price may be supported by policies and maintenance factors and remain in a relatively strong state. In the long run, Yuanxing's second - phase 2.8 million - ton capacity is expected to be put into production in August, which will increase market supply, and the soda ash futures price may face valuation pressure. In addition, if the inventory inflection point appears, that is, the inventory starts to rise, it may also lead to a price pullback. Traders need to beware of the short - selling risk brought about by the accelerated release of Yuanxing's capacity or the increase in inventory [12]
