[SMM Analysis] Futures Wild Swings and Sluggish Off-Season Trading Accelerate Stainless Steel Inventory Buildup SMM July 9 – This week, the pace of stainless steel social inventory buildup quickened, with the increase in core market inventory widening and inventory pressure becoming increasingly evident. Total inventory in the two core markets, Wuxi and Foshan, continued to rise, from 935,400 mt on July 2, 2026 to 943,700 mt on July 9, up 0.89% WoW, further reinforcing the off-season accumulation trend. This week, the stainless steel market remained in the traditional consumption off-season, with persistently weak end-user rigid demand and a marked acceleration in inventory buildup. During the week, SS futures were dominated by liquidity-driven disturbances, retreating after rapid rises amid wild swings. These futures fluctuations repeatedly unsettled spot market sentiment, with only sporadic concentrated transactions occurring and extremely poor sustainability; the market quickly reverted to the mediocre off-season trading activity. Meanwhile, major stainless steel mills ended their earlier efforts to hold prices firm and proactively lowered market guidance prices, further weakening overall bullish sentiment. Downstream end-users grew more cautious, with purchase willingness remaining subdued, sharply reducing the destocking efficiency of spot cargo. On the supply side, although the industry’s monthly production schedule pulled back somewhat, marginally easing the pressure of cargo release, this was insufficient to offset the bearish impact of significantly weaker off-season demand. The supply-demand mismatch intensified, ultimately driving the accelerated accumulation of stainless steel social inventories this week.

SMM July 9 – This week, the pace of stainless steel social inventory buildup accelerated, with the increase in core market inventories widening and inventory buildup pressure gradually surfacing. Total inventories in the two core markets of Wuxi and Foshan continued to rise, from 935,400 mt on July 2 to 943,700 mt on July 9, up 0.89% WoW, further intensifying the off-season inventory accumulation trend.

This week, the stainless steel market remained in a traditional consumption off-season pattern, with sluggish end-user rigid demand persisting and the pace of inventory buildup clearly accelerating. During the week, SS futures were mainly driven by capital-side disturbances, retreating after a rapid rise and swinging wildly, with the wild swings repeatedly unsettling spot market sentiment. Only occasional concentrated transactions occurred, with very poor sustainability, and then quickly returned to the off-season's mediocre trading conditions. Meanwhile, major stainless steel mills ended their earlier stance of holding prices firm and proactively lowered market guidance prices, further weakening overall bullish confidence. Downstream end-users grew more cautious, and their willingness to purchase remained weak, sharply reducing the destocking efficiency of spot cargo. On the supply side, although the industry's monthly production schedule declined overall, marginally easing the pressure from supply releases, it could not offset the negative impact of sharply weakening off-season demand. The supply-demand mismatch intensified, ultimately driving accelerated accumulation of stainless steel social inventories this week.

In summary, wild swings in futures disturbing market sentiment, steel mills' retreat from holding prices firm dragging down spot confidence, and persistently sluggish end-user transactions during the off-season were the core drivers behind the accelerated inventory buildup of stainless steel this week. The decline in production schedules on the supply side only slightly eased supply pressure and could not reverse the off-season inventory buildup trend. At present, stainless steel fundamentals are clearly weak, with no real recovery momentum on the demand side and weak trading sentiment. In the short term, the weak supply-demand pattern during the off-season will persist, and inventories will most likely continue to accumulate. Going forward, close attention should be paid to the pace of SS futures fluctuations, changes in downstream off-season rigid demand, steel mills' price adjustment strategies, and actual supply arrivals to assess whether the pace of inventory buildup can marginally converge.

[SMM Analysis] Raw Material Prices Generally Pull Back, Fail to Alleviate Narrowing Stainless Steel Mill Profits Stainless steel prices and production costs both declined this week, squeezing steel mill profit margins. Using 304 cold-rolled products as the calculation benchmark, the profit margin based on current raw material costs stood at 1.71%, while the margin based on inventory cost accounting was 0.48%. On the nickel-based raw material cost side, high-grade NPI prices exhibited a falling and pulling back trend this week. SS futures continued to pull back during the week, drastically increasing cost pressure on China's stainless steel mills. Coupled with pessimistic market expectations for the near term, the low purchase tender price for high-grade NPI announced by a major stainless steel mill drove a broad decline in psychological price levels for market-wide purchases. However, upstream suppliers maintained a relatively strong willingness to hold prices firm, creating significant divergence between upstream and downstream players, leaving transactions mired in a sluggish pattern. As of this Friday, the imported price including tax for Indonesian high-grade NPI with 10%-12% nickel grades fell by 6 yuan per nickel unit, settling at 1,137 yuan/mtu. In the stainless steel scrap market, stainless steel scrap prices drifted lower this week. Dragged down by the decline in SS futures and mills' low high-grade NPI tender prices, overall market sentiment was pessimistic. Mills adopted a cautious purchasing stance, trading activity remained insufficient, and the price center continued to shift downward. Although stainless steel scrap still held an economic advantage over NPI, this could not offset the impact of sluggish end-use demand and pessimistic expectations. Under the resonance of multiple negative factors, the cost support role failed, and prices are likely to continue consolidating on a weak note in the short term. As of this Friday, mainstream 304 off-cuts prices in Shanghai fell by 250 yuan/mt, with the latest quotation at approximately 10,150 yuan/mt. From the chromium-based raw material cost side, high-carbon ferrochrome prices remained stable this week...

[SMM Stainless Steel Scrap Market Weekly Review] SS Weakness and Sluggish Demand: Stainless Steel Scrap’s Cost Advantage Struggles Against Bearish Expectations This week, prices of 304 stainless steel scrap off-cuts in east China pulled back, with a quotation range of 10,100-10,200 yuan/mt; prices for the same grade of stainless steel scrap in the Foshan area also fell back, ranging from 10,000-10,300 yuan/mt. From the raw material cost side analysis, the cost of producing stainless steel entirely from stainless steel scrap is currently about 14,218.64 yuan/mt, while the cost of using high-grade NPI reaches 14,972.65 yuan/mt, still maintaining a large cost spread. This week, stainless steel scrap prices drifted lower. SS futures pulled back throughout the week, with bearish sentiment spreading on the futures side, directly dragging down spot prices of stainless steel products slightly. The weak futures set the overall market tone. On the spot side, mainstream stainless steel mills adopted a cautious approach due to higher production costs and uncertain market outlook, as their published high-grade NPI tender prices were low, further weighing on sentiment in the nickel-based raw material and scrap markets. As a result, some stainless steel mills suspended purchases of stainless steel scrap during the week, market buying interest weakened noticeably, overall trading was subdued, and the price center of stainless steel scrap continued to shift lower. Overall, the cost advantage struggled to offset the suppression from bearish market expectations. This week, stainless steel scrap still held a significant economic advantage over high-grade NPI, and the cost substitution logic has not reversed, providing some bottom support for scrap prices. However, overall market sentiment remains weak, steel mill cost pressure…

[SMM Stainless Steel Daily Review] Capital Disturbances and Off-Season Bearishness Weigh on Stainless Steel Futures and Spot, Inventory Accumulates According to SMM on July 10, SS futures fell further, pulling back. Although nonferrous metals had strengthened recently, SS was under capital pressure, extending its downtrend and declining further. As of the midday close, the most-traded SS contract settled at 14,320 yuan/mt. On the spot market front, weighed by the consecutive decline of SS futures, stainless steel mills' willingness to hold prices firm weakened noticeably, and they also lowered NPI purchase prices. Market confidence in the outlook was markedly insufficient, and overall transactions were in the doldrums. Traders cut prices to sell, with low-priced cargoes frequently appearing. The most-traded SS futures contract: At 10:15 a.m., SS2608 traded at 14,345 yuan/mt, down 30 yuan/mt from the previous trading day. Spot premiums for 304/2B in Wuxi were in the 525-925 yuan/mt range. In the spot market, the average price of cold-rolled 201/2B coil in Wuxi held steady; for cold-rolled, unedged 304/2B coil, the average price in Wuxi fell 125 yuan/mt, and the average in Foshan fell 150 yuan/mt; the cold-rolled 316L/2B coil price in Wuxi remained flat; the hot-rolled 316L/NO.1 coil in Wuxi was quoted unchanged; and cold-rolled 430/2B coil prices in both Wuxi and Foshan were unchanged. This week, macro and funding disturbances intensified, and stainless steel futures moved in an independent weak trend, with the futures chart significantly diverging from the pace of SHFE nickel and other nonferrous metals. During the week, fund sentiment switched repeatedly, driving SS futures into wild swings. The key support level of 14,500 yuan/mt was broken earlier, and the overall trend center continued to shift lower, ...
