供需同步走弱，钢价震荡运行

1. Report Industry Investment Rating - Not provided in the given content 2. Core Views - The supply and demand of steel are both weakening, and steel prices are fluctuating. Glass and soda ash are experiencing range - bound oscillations due to pre - holiday cautious sentiment. For double silicon, the market is mainly in a wait - and - see mode as the Spring Festival approaches [1][3] - Glass market fundamentals have no obvious improvement. Although the expected production halt in Shahe eases supply pressure, pre - holiday demand is weak, and inventory is accumulating. Soda ash supply is abundant with new production projects advancing, and pre - holiday demand is seasonally low [1] - The fundamentals of silicon manganese have improved slightly with expected increase in iron - water production, but inventory pressure remains high. The fundamentals of silicon iron are controllable, and demand is expected to improve marginally as steel mills resume production, but overall over - capacity restricts price increases [3] 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass contracts showed narrow - range fluctuations yesterday, with decreasing positions as the holiday nears. Spot prices are stable, but trading volume is low. This week, cold - repair of production lines increased, daily melting volume dropped, and inventory rose. Soda ash contracts also had narrow - range fluctuations, with low spot trading volume. This week, soda ash production increased slightly, heavy - ash inventory rose slightly, and light - ash inventory decreased [1] Supply - Demand and Logic - Glass fundamentals have no significant improvement. The expected production halt in Shahe eases supply pressure, but pre - holiday demand is weak, and inventory accumulation continues. Soda ash supply is in a loose pattern. With new production projects advancing, production remains high, and inventory is increasing. Pre - holiday demand drops seasonally, and the new production projects need to be monitored [1] Strategy - Glass: Range - bound fluctuations; Soda ash: Range - bound fluctuations; No strategies for inter - period and inter - variety trading [2] Double Silicon Market Analysis - Silicon manganese futures continued to fluctuate slightly, and the market was quiet with a strong holiday atmosphere. The price of 6517 silicon manganese is 5580 - 5680 yuan/ton in the northern market and 5700 - 5750 yuan/ton in the southern market. Silicon iron futures followed the overall black - metal market downwards, and the spot market was weak. Most of the market is in a wait - and - see mode. The price of 72 - grade silicon iron in the main production areas is 5250 - 5350 yuan/ton, and that of 75 - grade silicon iron is 5850 - 6000 yuan/ton [3] Supply - Demand and Logic - Silicon manganese fundamentals have improved slightly, and iron - water production is expected to increase, leading to marginal improvement in demand. However, inventory pressure is still high. The South African tariff policy may increase manganese ore costs. Silicon iron fundamentals are controllable. Enterprises are reducing production, and demand is expected to improve as steel mills resume production. But overall over - capacity restricts price increases, and inventory reduction and power - price policies need to be monitored [3] Strategy - Silicon manganese: Range - bound fluctuations; Silicon iron: Range - bound fluctuations [4]
