[SMM Tin Morning Brief: The Most-Traded SHFE Tin Contract Fluctuated Downward After Opening in the Night Session, and Spot Transactions Were Relatively Sluggish]

Silver prices remained in the doldrums today. After the spot-futures price spread narrowed, premiums in the spot market continued to decline. In the Shanghai market, mainstream quotations from suppliers of standard silver ingots in the morning session were adjusted down to a premium of 200 yuan/kg against TD, but downstream consumption remained sluggish. As rigid demand for raw materials decreased, some suppliers lowered premiums to sell off cargoes and close deals. Although some smelters were reluctant to sell, quoting silver ingots at a premium of 150 yuan/kg against the 2606 contract or a premium of 200 yuan/kg against TD, actual transactions were scarce. In the Shenzhen market, non-standard registered brand silver ingots were sold off at parity or slight discounts against TD. Downstream buyers made substantial counteroffers and remained cautious on the sidelines. Spot cargoes circulating in the market were ample, and overall market transactions turned weaker.

[Shanghai Spot Copper] Intraday trading in the spot market improved somewhat from yesterday. Suppliers still showed willingness to hold prices firm, but some suppliers’ sell-offs temporarily weighed on the market, causing spot premiums to decline somewhat in the second trading session. Coupled with the narrowing Contango price spread between nearby futures contracts, suppliers’ willingness to ship to delivery warehouses weakened somewhat, and spot premiums remained under pressure. Demand side, as copper prices fell, downstream enterprises may have had some restocking demand, but the current copper prices had limited actual appeal. Supply side, social inventory remained at a high level, but spot cargo available for actual circulation was relatively tight. Some warrants were already seen flowing out during the day, which may ease some pressure on spot supply. Meanwhile, the import window remained open, and expectations for subsequent inflows of cargo from outside China increased. Overall, amid the tug-of-war between sellers and buyers, Shanghai spot copper is expected to maintain the current discount structure overall tomorrow.

[SMM Silicon-Based PV Morning Briefing] Polysilicon: The quoted price for N-type recharging polysilicon was 42-49 yuan/kg. Polysilicon prices continued to decline recently, mainly affected by wafer price cuts and market sentiment. At present, low-priced polysilicon has already fallen below the cost line of some manufacturers, and the willingness to hold quotes firm has strengthened somewhat. The upstream market was also still watching wafer price moves. Wafer: In the market, 18X wafer prices were 1.00-1.05 yuan/piece, 210RN wafer prices were 1.1-1.15 yuan/piece, and 210N wafer prices were 1.3-1.35 yuan/piece. Wafer prices remained stable. Current selling prices have already fallen below cash cost, so the likelihood of another sharp price cut was relatively small.

[SMM Shanghai Spot Copper] Intraday trading in the spot market was subdued, while suppliers still showed willingness to hold prices firm. Downstream wait-and-see sentiment remained relatively strong, and spot premiums edged down slightly from yesterday. As the contango price spread between nearby contracts narrowed, suppliers' willingness to ship to delivery warehouses weakened somewhat, putting pressure on spot premiums. On the demand side, downstream buyers maintained just-in-time procurement, and transactions remained sluggish even after suppliers slightly lowered their quotations, as current copper prices had limited appeal to end-users. On the supply side, domestic copper and imported cargoes previously locked in at fixed prices continued to arrive, while social inventory remained at a high level. The outflow of warrants over the next two days may further weigh on spot premiums. Meanwhile, signs that the import window may still open persisted, and expectations for subsequent inflows of ex-China cargoes strengthened, further increasing supply-side pressure. Overall, amid a pattern of weak supply and demand, Shanghai spot copper premiums are expected to remain under pressure tomorrow, with a possibility of a slight widening.

SMM, March 17: During the day, the most-traded SHFE lead 2604 contract opened at about 16,450 yuan/mt. Boosted by broadly rising sentiment across the base metals complex in early trading, lead prices fluctuated upward and touched a high of 16,685 yuan/mt, then fluctuated lower. Near the close, SHFE lead prices fluctuated rangebound in a narrow range of 16,555-16,605 yuan/mt, and finally closed at 16,600 yuan/mt. A small bullish candlestick was recorded, up 285 yuan/mt, or 1.75%. Inventory at primary lead smelters continued to be digested, and suppliers showed a relatively strong willingness to hold prices firm. Losses at secondary lead enterprises worsened, prompting strong reluctance to sell and pronounced wait-and-see sentiment, while effective market supply shrank. After restocking at lower prices, downstream battery plants slowed procurement, with overall demand remaining weak and capping the rise in lead prices. Lead prices face limited upside room in the short term, and subsequent price moves should be watched for the impact of geopolitics, changes in operating rates at secondary lead enterprises in mid-to-late March, and downstream procurement conditions.
