China's antitrust regulator is demanding copper supply guarantees from Anglo American as a prerequisite for approving its $54 billion merger with Canada's Teck Resources. This regulatory pressure comes as Chinese smelters struggle with a severe shortage of raw feedstock.

SAMR's demand for copper concentrate guarantees

The State Administration for Market Regulation (SAMR) has requested that Anglo American commit to a steady flow of copper concentrate to protect domestic industrial supply. According to the report, these demands include specific volumes sold through traders, reflecting the concerns of Chinese smelters who have provided feedback to the regulator. Because China is a primary consumer of output from both Anglo American and Teck Resources,the regulator holds effective veto power over the transaction.

While the merger would result in a combined entity controlling roughly five percent of the global copper supply—well below the typical 10 to 15 percent competition threshold—the Chinese government is prioritizing resource security over traditional market-share metrics. As reported , the current remedies sought by SAMR do not include the sale of assets, but rather behavioral commitments regarding supply stability.

The 60 percent global cathode refining bottleneck

The urgency of the SAMR request is driven by a crisis in China's smelting sector, which refines up to 60 percent of the world's copper cathodes. Analysts suggest that refined copper output in China is expected to grow at its slowest pace since 2000 this year because smelters are fighting over dwindling raw materials. This scarcity is compounded by falling prices for byproduct sulphuric acid, which has further eroded profitability across the Chinese refining industry.

The Anglo American and Teck Resources merger, announced in 2025, represents a massive consolidation of unrefined volumes. much of Anglo American's current output from Chile and Peru is sold as concentrate to international buyers. If these volumes are diverted or restricted, the impact on the global supply chain could be significant, particularly for the custom smelters in China, Japan, and Europe that rely on these raw inputs.

From MMG nickel to the clean energy transition

This move by China is part of a broader global trend where antitrust reviews are used to secure critical minerals essential for the clean energy transition. executives at Rio Tinto, Glencore, and Anglo American have noted that national interest considerations now play a more prominent role in mining transactions. This "resource nationalism" is not limited to China; for example , the European Commission recently issued an antitrust warning to the Hong Kong-listed MMG over concerns that ferronickel supplies might be diverted away from European markets.

The complexity of these deals is highlighted by Anglo American's previous sale of nickel assets to MMG. In that instance, MMG had to propose long-term supply commitments to Europe to satisfy regulators. the current standoff between Anglo American and SAMR echoes this pattern, where corporate mergers become vehicles for state-level resource diplomacy.

The risk of shifting to index-linked spot pricing

One of the primary unknowns is how these supply guarantees will affect global pricing mechanisms. Industry analysts warn that if Anglo American and Teck Resources are forced to operate under state-mandated destination clauses, the industry may accelerate a shift away from traditional annual benchmark pricing toward index-linked spot pricing. Such a shift would fundamentally change how copper is valued and traded globally.

Furthermore, there is a lingering question regarding the survival of Western processing facilities. If the combined Anglo American and Teck Resources entity is forced to prioritize Chinese supply, it could hasten the closure of Western smelters already struggling with rising costs. With the companies expecting the deal to close by March 2027, the window for SAMR to negotiate these terms is narrowing, leaving the market to wonder exactly what volume commitments Anglo American is willing to concede to secure the deal.
