2025年玻璃纯碱11月策略报告：玻璃：库存转移、供给变动带来估值弹性纯碱：成本中枢上移新利空在产能投放-20251103

1. Report Industry Investment Rating The provided content does not mention the industry investment rating. 2. Core Viewpoints of the Report - Glass is expected to continue in a pattern of weak demand and strong expectations in November 2025, with the 01 contract likely to oscillate at the bottom. Attention should be paid to low - buying opportunities after the premium is reversed. In the long - term, the cost support of the glass industry will gradually strengthen [3][63]. - For soda ash, in the short - term, there is a risk of capacity clearance. The price is expected to continue to oscillate at the bottom. The SA01 contract should focus on the previous low support. In the long - term, the valuation of soda ash is not optimistic due to the expected new capacity release [4][102]. 3. Summary by Relevant Catalogs 3.1 Glass 2025 November Strategy Report 3.1.1 Glass 2025 October Review - In October, glass supply was stable, demand was weak, and the speculative demand in the middle - stream turned into speculative supply. The upstream inventory increased rapidly, and the prices in the main producing areas dropped. By the end of the month, the spot price stabilized at a low level [11]. - The FG01 - 05 spread continued the reverse - spread trend, corresponding to the weak reality and the market's expectation of environmental protection and capacity - restriction policies [11]. - In terms of supply, the daily melting capacity was stable in October, with 1 line ignited and no cold - repair. The production cost increased slightly, and the profit situation deteriorated [14]. - On the demand side, the deep - processing orders decreased, and the mid - and downstream inventory decreased. The real - estate data was poor, white - goods production decreased year - on - year, and automobile production maintained a high growth rate [20][22]. 3.1.2 Glass 2025 November Outlook - Demand: Affected by the real - estate cycle, glass demand is expected to remain weak. In November, the rigid demand may be weak and stable seasonally. Attention should be paid to whether the middle - stream replenishes inventory [50]. - Supply: In November, the ignition and cold - repair of production lines are expected to be relatively balanced. The supply may be affected by cold - repair and policy implementation, but the medium - term positive impact is limited [55]. - Cost: In October, the increase in fuel prices raised the production cost of the glass industry. The cost support for prices will gradually strengthen [60]. 3.1.3 Glass Balance Sheet and Strategy Outlook - In November, the glass supply - demand pattern is expected to remain weak year - on - year, and the upstream inventory is expected to be worse than that in the fourth quarter of last year. - The valuation is driven by supply - side factors and potential mid - and downstream inventory replenishment. The 01 contract is expected to oscillate at the bottom, and attention should be paid to low - buying opportunities. The 01 - 05 spread has limited room to widen [63]. 3.2 Soda Ash 2025 November Strategy Report 3.2.1 Soda Ash 2025 October Review - In October, the high - supply and high - inventory pattern of soda ash remained unchanged. The spot price decreased slightly after the National Day, and the production cost increased due to the rise in coal prices. The SA01 contract oscillated in the range of 1200 - 1275 yuan/ton [70]. - In terms of supply, the production of soda ash remained high, but the alkali plant's initiative to reduce the load increased. The cost increased, and the industry's loss expanded [79]. - On the demand side, the demand for heavy soda ash from the glass industry was stable, and the demand for light soda ash was supported. The net export of soda ash in September remained at a relatively high level [82][86]. - In terms of inventory, the upstream inventory increased seasonally at the beginning of the month and then changed little under the drive of downstream low - price replenishment [89]. 3.2.2 Soda Ash 2025 November Outlook - Supply: The capacity clearance of the soda ash industry is expected to continue in November, but the mid - term price is still under pressure due to the expected release of 2.8 million tons of new capacity from Yuangxing Phase II [95]. - Demand: The rigid demand for light soda ash is supported, and the demand for heavy soda ash from the glass industry is expected to be stable [98][99]. 3.2.3 Soda Ash Balance Sheet and Strategy Outlook - In November, the soda ash supply - demand surplus pattern has not changed. The price is affected by the progress of Yuangxing Phase II's production. In the long - term, the valuation of soda ash is not optimistic. - The current price of soda ash is expected to continue to oscillate at the bottom. The SA01 contract should focus on the previous low support. The 01 - 05 spread lacks fundamental drivers and is more affected by macro factors [102].
