A Familiar Cycle With New Drivers
Resource nationalism is not new. From the OPEC nationalisations of the 1970s to the Latin American wave of the 2000s, host governments have periodically reasserted sovereign control over strategic resources whenever commodity prices, political conditions, and fiscal needs align. What makes the 2026 cycle different is the underlying mix of drivers: the global race to secure critical minerals for the energy transition, persistent post-pandemic budget pressure, and a wave of populist governments elected on platforms of economic sovereignty.
The result is a measurable uptick in measures that affect foreign investors in the extractives and energy sectors — and a corresponding pipeline of treaty-based disputes.
The Critical Minerals Frontier
Lithium, copper, cobalt, rare earths, and nickel sit at the centre of the current cycle. The same minerals that power the energy transition are concentrated in jurisdictions where the historical pattern of resource governance is weakest. Three patterns are visible in 2026:
- Outright nationalisation — A small number of governments have announced direct state ownership of critical mineral deposits, sometimes following constitutional reforms.
- Indigenisation requirements — A larger group of jurisdictions has imposed mandatory local equity participation, local processing requirements, or export controls on raw ores.
- Royalty and tax adjustments — The most common measure: retroactive increases in royalty rates, windfall taxes, or sliding-scale fiscal regimes tied to commodity prices.
Each of these measures sits on a different point of the expropriation spectrum, and each engages different treaty protections. Outright nationalisations engage classic expropriation clauses. Indigenisation requirements often trigger national treatment and FET protections. Royalty changes typically test the boundaries of legitimate regulation versus arbitrary state conduct.
Energy: The Transition Cuts Both Ways
The energy sector is producing disputes from both directions of the transition. On one hand, renewables investors continue to file claims arising from tariff cuts, retroactive subsidy reductions, and regulatory reversals in jurisdictions that initially courted renewable capital. On the other, oil and gas investors face an emerging wave of measures connected to climate policy — accelerated permit revocations, restrictions on new exploration licences, and tax regimes targeting fossil fuel producers.
These transitional measures sit in a particularly contested zone of investment treaty law. States invoke the right to regulate for climate purposes; investors point to legitimate expectations grounded in specific licences and assurances. The tribunal record is still developing, but several 2025–2026 awards suggest a willingness to scrutinise the proportionality and consistency of climate-driven measures rather than defer to them automatically.
Geographic Hotspots in 2026
The countries to watch in 2026 break down roughly as follows:
- Andean Latin America — Continued political volatility in Chile, Peru, Bolivia, and Colombia is driving mining-sector measures, particularly in lithium and copper.
- Mexico — Constitutional reforms affecting the electricity and mining sectors continue to generate filings under both NAFTA legacy provisions and USMCA.
- West and Southern Africa — Mining code revisions in DRC, Zambia, Mali, and Burkina Faso have produced an active dispute pipeline.
- Indonesia and the Philippines — Export bans on raw ores and shifting downstream-processing requirements are generating tensions with foreign-invested miners.
- Central Asia — Renegotiation of legacy oil and gas production-sharing agreements is producing both arbitration filings and pre-dispute leverage plays.
Why the Old Risk Models Fall Short
Traditional country-risk frameworks struggle with resource nationalism because the relevant signals are dispersed, multilingual, and sectoral. A new mining code published in the official gazette of a francophone West African state is genuinely material to an investor — and to that investor's potential counsel — but it will almost never surface in the English-language news flow that most firms rely on.
Effective monitoring requires three things that human-only practices cannot deliver at scale:
- Coverage of primary sources — Government gazettes, regulatory filings, and parliamentary records, not just press coverage.
- Multilingual ingestion — French, Spanish, Portuguese, Russian, Indonesian, and Mandarin sources alongside English.
- Continuous classification — Tagging each measure by sector, country, severity, and likely treaty engagement so that practitioners see relevance scores rather than raw news.

The Strategic Implication
For investors, the 2026 cycle means that the static "country risk" view of treaty protection is obsolete. Risk must be tracked as a live, continuously updated picture, with attention to specific measures rather than aggregate scores.
For arbitration counsel, the same logic applies to dispute origination. The next major mining or energy claim will not arrive as an inbound call. It will be visible — for those watching the right sources — in a regulatory announcement, a presidential decree, or a tax bill, weeks or months before any investor formally decides to litigate. The firms that systematically watch those sources are the firms that will define the practice.
Frequently asked questions
What is resource nationalism?
Resource nationalism is the policy posture in which a host government reasserts sovereign control over strategic natural resources — through nationalisation, indigenisation, retroactive royalty or tax increases, or export controls. It tends to surge during cycles of high commodity prices, fiscal pressure, and political populism.
Which minerals and sectors are most affected in 2026?
The 2026 cycle is concentrated in critical minerals — lithium, copper, cobalt, rare earths, nickel — alongside oil, gas, and renewables. Mining concessions, fiscal regimes, and export rules are the most common subjects of new state measures.
Which countries are the main hotspots?
Andean Latin America (Chile, Peru, Bolivia, Colombia) for lithium and copper; Mexico for electricity and mining reforms; West and Southern Africa (DRC, Zambia, Mali, Burkina Faso) for mining codes; Indonesia and the Philippines for export bans; and Central Asia for legacy oil and gas renegotiations.
What treaty protections apply to resource nationalism?
Outright nationalisations engage classic expropriation clauses. Indigenisation requirements often engage national treatment and FET. Royalty and tax changes test the boundary between legitimate regulation and arbitrary state conduct.
Why are traditional country-risk models insufficient?
Country-risk scores update slowly and aggregate signals. Resource-nationalism measures appear as specific decrees and gazette notices, often in local languages. Effective monitoring requires multilingual ingestion of primary sources and continuous classification by sector and treaty engagement.
