Mozambique Mandates a Free-Carry State Stake and Bans Raw Exports — With Retroactivity Left Unresolved

What happened

On 3 June 2026, Mozambique's President Daniel Chapo signed Lei No. 7 of 2026 into law, replacing the country's 2014 mining regime with one of the most structurally ambitious resource-sovereignty frameworks enacted in Southern Africa in recent decades. The law had passed Parliament in May 2026. Its two headline provisions operate in tandem: a mandatory minimum 15% free-carried, non-dilutable equity stake for a newly created state entity — the Empresa Nacional de Minas (ENM) — in every mining project at every stage of the value chain; and a blanket prohibition on the export of raw or semi-processed minerals unless an operator obtains ministerial authorisation supported by an approved domestic processing plan.

The equity mechanism is structurally aggressive. ENM receives its 15% position without contributing any proportionate share of capital expenditure during the development phase — the entire financial burden of project development sits with the private investor, who receives at most 85% of equity returns. This represents a threefold increase over the prior discretionary 5% free-carried model that had applied to large-scale projects under public-private partnership law. For projects classified as 'strategic minerals' — a list whose final composition has not yet been published — the state's share may rise above 15%. Oversight of the sector passes from the former Instituto Nacional de Minas to a new regulator, the Autoridade Reguladora de Minas (AREMI).

The export prohibition is the law's most contested provision in practice. Mozambique currently lacks the industrial infrastructure — processing equipment, high-voltage power, specialist expertise, and logistics connectivity — to absorb its mineral output domestically at scale. The implementing regulations that would define the ministerial exemption mechanism, set out export quotas by mineral category, and specify processing-plan content standards had not been published as of this writing. The Mozambique Mining Journal reported in its July–August 2026 issue that the law's most consequential unresolved question is whether it applies retroactively to existing mines operating under stabilisation clauses — a question the text of the law does not clearly answer.

That ambiguity has already converted into a live docket. The Mozambique Mining Journal also reported that Galp Energia SGPS, Galp Energia Portugal Holdings B.V., and Galp East Africa B.V. filed a request for ICSID arbitration against the Republic of Mozambique, registered on 26 June 2026 as Case No. ARB/26/31, arising from a tax dispute over the treatment of Galp's sale of its 10% stake in Area 4 of the Rovuma Basin to Abu Dhabi's ADNOC — a dispute that illustrates the broader pattern of Mozambique's fiscal framework generating investor-state friction independent of the mining law itself.

Why it matters for dispute formation

The retroactivity gap is the single largest near-term source of legal risk. The new law does not explicitly state whether it applies to operations governed by pre-existing long-term agreements — development agreements, concession contracts, or Mining Concessions issued under Lei No. 20/2014 — that contain tax or regulatory stabilisation clauses. King & Spalding's analysis of the law notes that it also codifies a broad contractual renegotiation clause, under which the state may seek to reopen mining contracts where there has been a 'substantial change of circumstances' affecting the economic, financial, environmental, technological, or legal basis of the contract, including shifts in reference market prices and — crucially — 'extraordinary gains.' The breadth of those triggers creates an asymmetric risk profile in which the state retains a standing option to reopen contractual terms at the precise moment a project becomes most valuable.

For the graphite sector in particular, the layers compound. Syrah Resources' Balama operation holds long-term agreements that may provide contractual protection, but the US Development Finance Corporation's proposed equity conversion in Syrah adds a sovereign-to-sovereign dimension: any future renegotiation between Maputo and Syrah would implicitly involve the US government as an equity stakeholder, altering the political calculus on both sides. At Ancuabe, the pending Shandong Yulong Gold acquisition of a 70% stake still requires state approval under a framework now designed to maximise Mozambican sovereign value capture — making completion uncertainty a structurally embedded deal risk rather than a tail scenario.

The Chamber of Mines of Mozambique has publicly warned that the mandatory free-carry provision could deter foreign investment and undermine the country's attractiveness as a mining destination. The complaint reflects a standard counterparty-risk escalation sequence: industry warning, regulatory silence on implementing detail, investor uncertainty, and — if stabilisation-clause claims are rejected in domestic proceedings — international arbitration. The Galp ICSID filing, while rooted in a separate tax dispute over the Rovuma gas basin, confirms that Maputo's willingness to face investor-state proceedings is already being tested across the extractives sector and that at least some foreign investors regard domestic resolution as insufficient.

Three treaty pathways are available to investors whose existing contracts are reached by the new law. Mozambique is party to bilateral investment treaties with Portugal, the United Kingdom, Switzerland, and the Netherlands, among others, all of which carry fair and equitable treatment and indirect expropriation protections. A retroactive application of the free-carry requirement to an investor who negotiated a stabilisation clause under the 2014 regime — and who relied on that clause when committing capital — would be a strong candidate for an FET claim, particularly if the implementing regulations define the exemption process in a manner that is opaque or discretionary. AREMI's gatekeeping role over both licence approvals and export authorisations concentrates leverage in a single regulatory body whose independence and procedural rules have not yet been tested in practice.

Who's exposed

What to watch

• Publication of implementing regulations defining AREMI's export-authorisation process, the 'strategic minerals' list, and the ministerial exemption criteria — the primary near-term trigger for dispute crystallisation.
• Syrah Resources' formal disclosure of its position on ENM equity entitlement at Balama, and whether the US DFC's involvement alters Maputo's approach to renegotiation.
• Progress of the Shandong Yulong Gold / Triton Minerals Ancuabe transaction through the new ministerial approval gateway — a public indicator of how the government will exercise its discretion under the new regime.
• Any further ICSID or ICC filings by existing Mozambican mining concession holders invoking stabilisation clause protections against retroactive application of Lei No. 7 of 2026.
