SMM, March 17: The SHFE aluminum 04 contract opened higher and extended gains today, with strong bullish sentiment in the market. Sellers held prices firm, buyers showed greater price acceptance, and purchasing enthusiasm also increased.

Traders maintained strong bullish sentiment and high enthusiasm for purchase, with overall trading volume relatively large. As suppliers basically finished shipments, circulating spot availability became tight, and market quotations continued to rise, but the transaction scale was relatively small. In the end, the actual transaction price range in the central China market was around 10 yuan below the central China price to 40 yuan above the central China price. Today, the central China market shipment sentiment index was 2.6, down 0.02 MoM; the purchasing sentiment index was 2.38, up 0.02 MoM.

[Geopolitical Tensions Combined With Deferred Interest Rate Cut Expectations Leave SHFE Aluminum Under Short-Term Pressure but Fluctuating at Highs] Against the backdrop of continued tightening LME liquidity, LME aluminum still has upward momentum, with strong support from prices outside China, and is expected to maintain a backwardation structure in the short term. China remains in a phase of high inventory coupled with weak fundamentals, and its upward momentum is significantly weaker than that outside China. Amid divergent domestic and external drivers, the SHFE/LME price ratio is expected to continue weakening, and aluminum prices are still expected to fluctuate at highs in the short term.

In the Shanghai market, during early trading, mainstream quotations from suppliers of national-standard silver ingots were at premiums of 400 yuan/kg against TD, but downstream consumption remained sluggish.

Some downstream clients mentioned that for bulk purchases exceeding 1 mt, transaction premiums could be negotiated with suppliers down to 250-300 yuan/kg. In South China, smelters quoted silver ingots at a premium of 250 yuan/kg against the 2606 contract or a premium of 400 yuan/kg against TD, but actual transactions were scarce. Suppliers still mainly adjusted prices to drive shipments, while downstream players remained cautious and on the sidelines, and spot market trading stayed sluggish.

[SMM Tin Midday Review: The Center of the Most-Traded Contract Rebounded Slightly, and Market Transactions Weakened After Downstream Enterprises Restocked]

[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.
