Price Spread Between Futures Contracts Weighs on Market Sentiment; North China Spot Discounts Continue to Widen [SMM North China Spot Copper]

According to the National Bureau of Statistics, national sulfuric acid (100% basis) output in June 2026 reached approximately 7.923 million tons (vs. 8.365 million in May, 8.948 million in April, and 9.637 million in March, showing a month‑on‑month decline). The year‑on‑year change for the month was about ‑10%. For the first half of the year (January–June), cumulative production totaled roughly 52.223 million tons, a year‑on‑year decrease of about ‑0.1% (down from +1.9% in the January–May period, mainly due to the sharp 10% drop in June). Production remains heavily concentrated in smelting and phosphate‑fertilizer provinces such as Yunnan, Inner Mongolia, Guangxi, Anhui, Henan, and Shandong—with Yunnan ranking first at about 1.24 million tons per month. Smelter acid (by‑product from copper/zinc processing) forms the supply backbone, while acid for phosphate fertilizer drives the bulk of demand.

[Cochilco Again Lowers 2026 Chilean Copper Production Forecast; H2 Recovery Still Has Room to Materialize] Cochilco has recently lowered its 2026 Chilean copper production forecast to 5.27 million mt, down 2.6% YoY, mainly due to lower grades at large mines, maintenance, slower project ramp-ups and operational constraints in H1. Over the same period, China imported 4.2808 million mt of copper concentrates from Chile, down 7.9% YoY, with Chile’s share of China’s copper concentrate imports falling to 29.3%; the contribution of Chilean supply to the Chinese market weakened temporarily. However, most miners maintained their full-year production guidance, mainly banking on H2 recovery from the switch to higher-grade ore zones, the completion of maintenance, and project ramp-ups. Going forward, whether Chilean production rebounds on schedule will continue to affect the global copper concentrate supply-demand balance and the TC trend.
