Spot copper concentrate TC/RCs down marginally ahead of Chinese holidays: LME Week

Spot trading in the copper concentrate market was inactive in the week to Friday September 29, with Chinese participants in holiday mode ahead of China’s weeklong break for the Mid-Autumn Festival and National Day (September 29-October 6)

Fastmarkets’ copper concentrates treatment charge (TC) index, cif Asia Pacific, was calculated at $87.70 per tonne on Friday, the lowest level since June.


Smelters’ buying level was mainly assessed at the low to mid $90s per tonne, but some participants saw the number below $90 per tonne, with more spot inquiries expected to come in.

Trader sources noted that Chinese smelters were showing increased interest in buying material. The increased demand was coming in part due to smelter expansions, one trader source said.

The trader added that this was leading to some increased buying interest among traders, noting they had seen some buying by traders potentially because they were short of material. One producer source also noted they had seen some traders buying to cover themselves.

The producer source also added that the gap between clean and both complex and blended concentrate was quite wide at the moment, and a number of sources have commented on this growing spread in recent weeks.

In addition, market focus has shifted to the upcoming LME Week in London, to be held during the second week of October. This also contributed to the quiet conditions in the market.

Capital is flowing back into junior mining, but selectively. Investment is increasingly favouring development‑stage assets with clearer paths to production, supported by government funding and strategic partnerships. While demand for critical minerals underpins the cycle, early‑stage explorers continue to struggle for capital as investors prioritise discipline, ESG alignment and near‑term cash flow.
China’s emergence over the past two decades has reshaped global trade. What began as rapid export-led expansion in the early 2000s has evolved into a far more strategic model: one centered on control of intermediate goods, deep integration into global supply chains, and the creation of structural dependencies across industries and regions, according to Mexico’s former ambassador to China, Jorge Guajardo.
The US has stepped up calls for its allies to accept higher costs for sourcing critical minerals outside China, arguing that supply chain security must take precedence over price efficiency – a stance that is reshaping expectations across metals markets but has yet to translate into durable pricing support.
