A New Era of Regulatory Activism
Over the past several years, governments across Latin America, Africa, and Central Asia have accelerated efforts to reassert control over natural resources, critical infrastructure, and strategic industries. What was once limited to isolated cases of expropriation has evolved into a broader pattern of regulatory activism that directly impacts foreign investors.
This shift isn't random. It's driven by a convergence of factors: rising commodity prices that make resource nationalism more attractive, domestic political pressure to capture more value from foreign investment, and a growing willingness among states to test the boundaries of bilateral investment treaties.
Where the Risk Is Concentrated
While regulatory risk exists everywhere, certain sectors and regions are seeing disproportionate activity:
Mining and Natural Resources
Several African nations have introduced new mining codes that increase royalty rates, mandate local ownership stakes, or impose processing requirements that fundamentally alter the economics of existing concessions. Foreign operators who invested under one set of rules now face a materially different regulatory environment — often without adequate transition provisions.
Energy and Renewables
Governments in Southern Europe and Latin America have retroactively modified renewable energy subsidies, cutting feed-in tariffs that were guaranteed to investors. This has already generated a wave of ICSID claims, and similar patterns are emerging in new jurisdictions as governments grapple with the fiscal cost of energy transition incentives.
Telecommunications
Spectrum license revocations, forced infrastructure sharing mandates, and sudden changes to foreign ownership caps have created significant exposure for telecom investors in parts of Asia and Africa. These regulatory shifts often occur with little notice and are difficult to challenge through domestic legal channels.
Banking and Finance
New capital controls, forced conversion requirements, and restrictions on profit repatriation are increasingly common in economies facing currency pressure. For foreign banks and financial institutions, these measures can effectively trap capital in-country.
The Treaty Landscape Is Shifting Too
It's not just host state behavior that's changing. The treaty framework itself is in flux. Several countries have terminated or renegotiated bilateral investment treaties, narrowing the protections available to foreign investors. Others have introduced new model BITs with expanded exceptions for regulatory measures taken in the public interest.
For arbitration lawyers, this means that the window for bringing claims under older, more investor-friendly treaties is narrowing. Understanding which treaties are still in force, which are in sunset periods, and which have been replaced with less favorable terms is now essential baseline knowledge.
Why Speed Matters
The challenge for law firms is that these regulatory changes happen fast and across dozens of jurisdictions simultaneously. A new mining code in the Democratic Republic of Congo, a tax reform in Chile, and a spectrum revocation in Myanmar can all occur in the same week — each potentially triggering treaty claims worth hundreds of millions.
Firms that rely on traditional monitoring methods — personal networks, industry conferences, and English-language news — will inevitably miss signals from jurisdictions where they don't have on-the-ground presence. By the time a regulatory change makes it into international legal publications, the first-mover advantage is gone.
Turning Risk Into Opportunity
For firms that can systematically track regulatory changes across all relevant jurisdictions, the current environment represents an unprecedented opportunity. Every new regulatory measure that impacts foreign investors is a potential mandate. Every terminated BIT creates urgency for investors to understand their remaining protections.
The firms that will thrive in this environment are the ones with the infrastructure to detect these changes early, assess their treaty implications quickly, and reach affected investors before anyone else does. Regulatory risk is rising — and so is the value of being the first to know about it.
