Barro Alto: The MMG nickel deal faces a formal challenge from the European Commission, which sent the Chinese-controlled miner a Statement of Objections on 16 September 2026 over its planned purchase of Anglo American’s nickel business. The assets sit in Brazil and include two operating ferronickel facilities, among them the Barro Alto site in Goiás, and two greenfield development projects.

Competition officials say the MMG nickel deal could let the buyer divert supplies of low-carbon ferronickel away from Europe. Their preliminary view is that the market for that product is highly concentrated and that the target business holds substantial market power. Less supply for European buyers would push up costs for stainless steel producers, which use ferronickel as a core input.

The ownership chain explains the concern. MMG is controlled by China Minmetals, and China Minmetals is controlled by SASAC, the Chinese state body that also controls several stainless steel producers. The Commission fears that supply could be steered toward those sister companies, leaving independent European mills with fewer sources and higher prices.

The timeline shows how long the file has run. MMG notified the transaction on 16 September 2025, and the Commission opened its in-depth investigation on 4 November 2025. A final decision is due by 30 November 2026, which leaves under eight weeks from today for the company to answer the objections and for officials to weigh the response.

A Statement of Objections is a procedural step, not a verdict. It sets out the Commission’s concerns and gives MMG the chance to reply, and the institution stresses that it does not prejudge the final outcome. Competition Commissioner Teresa Ribera’s team can clear the deal, clear it with conditions, or block it.

Three questions will shape the decision on the MMG nickel deal. The first is whether low-carbon ferronickel has enough alternative suppliers to keep European prices stable. The second is whether state ownership changes the buyer’s incentives once it controls scarce supply. The third is whether any commitments from MMG could realistically guarantee deliveries to European customers after the sale closes.

For European stainless steel producers, the MMG nickel deal is a test of whether Brussels will treat access to a single raw material as a competition issue. The Commission’s own phrasing, that the buyer could divert low-carbon supplies, shows that it sees the risk as a loss of choice for customers rather than a simple change in ownership.

The case matters beyond one transaction. Europe has pushed to secure critical raw materials and to reduce dependence on supply chains it cannot influence, and stainless steel is a downstream industry that still relies on imported inputs. The way the Commission handles the MMG nickel deal will show how far competition enforcement now reaches into supply security, particularly when state-linked buyers are involved.
