AMSA Faces Tribunal Over Monopsony Abuse of Black-Owned Mine

Manngwe Mining, a 100% Black-owned mining company, has approached the Competition Tribunal accusing ArcelorMittal South Africa (AMSA) of abusing its monopsony power. Manngwe alleges AMSA, as the sole buyer of iron ore from the Assen Mine near Brits, deliberately withheld purchase orders to force the Black shareholders to surrender their equity. AMSA denies the claims, stating the equity options were tied to financial loans and operational support provided to the struggling mine.

How Did ArcelorMittal Use Its Market Power Against Manngwe Mining?

A monopsony occurs when a single powerful buyer dominates a market, effectively trapping suppliers. In the North West province, AMSA held this position as the exclusive buyer of iron ore produced at Manngwe's Assen Mine. Mutheiwana Rambuwani, CEO of Manngwe Mining, stated that AMSA weaponized this position. According to Rambuwani, the steel giant withheld and rationed purchase orders, making their resumption conditional on Manngwe surrendering its hard-won equity.

This is not merely a commercial disagreement. It is a stark illustration of how structural economic imbalances continue to disadvantage Black industrialists. When a corporate behemoth controls the only pipeline to market, the supplier has no real freedom. Rambuwani emphasized that AMSA's conduct undermined over a decade of investment, development, and community-centered growth.

To make the resumption of orders conditional on our parting with equity, placed unsustainable pressure on the business. We believe that conduct is unfair, and not in line with the spirit of the Competition Act and the protections it affords suppliers.

Is Financial Support a Trojan Horse for Equity Extraction?

AMSA has defended its actions, claiming the relationship deteriorated due to inconsistent supply, quality concerns, pricing issues, and governance instability at the Assen Mine. The steel producer insists it engaged with Manngwe to find a commercially sustainable path forward. AMSA claims it provided financial assistance, accelerated payments, and technical support since 2016.

However, a critical examination reveals a familiar historical pattern. The financial assistance AMSA references included a loan on favorable terms. When Manngwe struggled, AMSA proposed that certain options be granted to AMSA in the Supply Agreement to address the outstanding loan and secure long-term supply. To the observer grounded in the realities of South African economic transformation, this looks less like a lifeline and more like a debt trap. When a dominant corporate entity provides loans to a Black-owned enterprise and then demands ownership when operational challenges arise, it mirrors the predatory practices of economic subjugation that have characterized centuries of exploitation in this country.

AMSA stated it did not coerce any representative of Manngwe Mining into signing documentation, and that its procurement decisions consider transformation and B-BBEE. Yet, the outcome tells a different story. A 100% Black-owned business stands to lose its equity, while the corporate giant consolidates its grip on the supply chain.

What Are the Stakes for the Community?

The consequences of this corporate bullying extend far beyond boardroom negotiations. The Assen Iron Ore Mine is a vital economic artery for the surrounding communities of Rasai and Kwaarikraal villages. Rambuwani highlighted that the reputational impact of the dispute has created deep uncertainty among workers, families, and suppliers who depend on the operation.

Our foremost concern is the people who depend on this enterprise, our employees, our suppliers, our shareholders and our community. They built the Assen operation into the going concern it is today. Those are the livelihoods now at stake, and safeguarding them is our responsibility.

Black livelihoods are routinely treated as collateral damage in the pursuit of corporate consolidation. Manngwe Mining maintains that a negotiated resolution is achievable, one that keeps the mine in the hands of its current shareholders while continuing to supply AMSA on fair commercial terms. The question remains whether AMSA will respect Black ownership or continue to leverage its market dominance to extract wealth generated by Black labor and Black capital.

What is a monopsony?

A monopsony is a market condition where a single buyer dominates, giving that buyer excessive power to dictate terms and prices to suppliers. It is the mirror image of a monopoly, where a single seller dominates the market.

Why is Manngwe Mining approaching the Competition Tribunal?

Manngwe Mining is seeking interim relief from the Competition Tribunal because it alleges AMSA abused its dominant monopsony position. The Black-owned company argues that AMSA illegally withheld purchase orders to force Manngwe to surrender its equity, violating the Competition Act 89 of 1998.

How has ArcelorMittal responded to the monopsony allegations?

ArcelorMittal South Africa denies the allegations of abuse. The company claims it provided financial, commercial, and technical support to Manngwe Mining since 2016. AMSA asserts that equity options were agreed upon to address outstanding loans and secure long-term supply, not to destroy the Black-owned business.
