Persediaan katoda tembaga di gudang berikat Tiongkok SMM naik menjadi 35.200 mt

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, SMM recorded Shanghai social inventory at 79,300 mt, up 1,000 mt WoW from this Monday; Jiangsu social inventory at 18,100 mt, flat WoW from this Monday. Overall inventory in east China edged up, and spot supply has yet to show any clear tightening. With delivery approaching, the intermonth Back price spread between futures contracts further widened to 600–750 yuan/mt. Higher contract rollover costs prompted some suppliers to accelerate spot sales, and quotes against the 2608 contract quickly moved lower accordingly; meanwhile, some deliverable-brand cargo meeting delivery standards flowed into the warrant channel, further differentiating spot cargo flows. After intraday discounts widened to around 300 yuan/mt, some market participants began to purchase, but trades clearly skewed toward cargo with lower prices, higher brand recognition, or better fit with their own production needs. Downstream buyers had ample choices and became more stringent in screening by brand and price, while actual end-use demand has yet to show any obvious improvement. As delivery neared, some suppliers had attempted to shift to quoting against the 2609 contract, with offers around a premium of 400 yuan/mt; the market may gradually enter a phase where the 2608 and 2609 contracts serve as dual benchmarks in parallel. It should be noted that the apparent uplift in premiums after contract rollover mainly came from the Back spread switch and does not indicate a substantive strengthening of spot supply and demand. Overall, if quoting continues against the 2608 contract, spot cargo may remain at relatively deep discounts; as the pricing benchmark gradually shifts to the 2609 contract, quotes are set to recover markedly, but transaction divergence among brands is expected to persist.

Menurut Biro Statistik Nasional, produksi asam sulfat nasional (basis 100%) pada Juni 2026 mencapai sekitar 7,923 juta ton (dibandingkan 8,365 juta ton pada Mei, 8,948 juta ton pada April, dan 9,637 juta ton pada Maret, menunjukkan penurunan dibanding bulan sebelumnya). Perubahan tahun-ke-tahun untuk bulan tersebut sekitar -10%. Untuk semester pertama tahun ini (Januari–Juni), produksi kumulatif mencapai sekitar 52,223 juta ton, dengan perubahan tahun-ke-tahun sekitar -0,1% (turun dari +1,9% pada periode Januari–Mei, terutama akibat penurunan tajam 10% pada Juni). Produksi masih sangat terkonsentrasi di provinsi-provinsi peleburan dan pupuk fosfat seperti Yunnan, Mongolia Dalam, Guangxi, Anhui, Henan, dan Shandong—dengan Yunnan menempati urutan pertama sekitar 1,24 juta ton per bulan. Asam smelter (produk samping dari pengolahan tembaga/seng) menjadi tulang punggung pasokan, sementara asam untuk pupuk fosfat mendorong sebagian besar permintaan.
