[SMM Analysis] Futures Broke Below Key Support and Moved Lower; Peak-Season Preheating Fell Through, and Stainless Steel Inventory Continued a Mild Buildup

SMM reported on August 27 that stainless steel social inventory continued to build up this week, with the inventory midpoint moving further higher and pressure from piled-up market supply steadily increasing. Total inventory in the two core markets of Wuxi and Foshan rose further, increasing from 925,100 mt on August 20, 2026 to 927,300 mt in the latest period, up 0.24% WoW. The pace of inventory buildup persisted, and industry-wide inventory pressure continued to intensify.

This week, expectations for a peak-season recovery in the stainless steel market completely fell through, with persistently weak end-use demand being the core driver of the inventory buildup. Entering late August, the market’s traditional September-October peak season stock-up-in-advance demand failed to materialize, and the recovery in rigid end-use demand was absent. Meanwhile, SS futures moved further lower during the week and effectively broke below the key support level of 14,000 yuan/mt. Market pessimism continued to ferment, wait-and-see sentiment among downstream players and traders intensified, spot purchase transactions remained sluggish, and the efficiency of supply digestion stayed at a low level. Supply-side pressure also rose in tandem. Steel mills’ production schedules rebounded somewhat this month, overall supply releases remained ample, and, coupled with relatively heavy pressure to draw down steel mills’ own inventories, willingness to sell was strong. Supply in circulation continued to be released, driving a steady accumulation in social inventory. Overall, the key reasons stainless steel inventory continued to build up this week were the breakdown and weakening of futures undermining market confidence, the absence of pre-peak-season demand, and persistently sluggish end-use transactions. Steel mills’ high production schedules, together with proactive selling, further amplified inventory pressure. At present, weak stainless steel fundamentals continued to dominate the market, and there were no clear signs of a near-term demand repair. Under the mismatch of steadily released supply and persistently weak demand, the subsequent trend of social inventory buildup may continue, and inventory pressure still has further upside room.
