Tanzania's Critical Minerals Strategy: Attracting Long-term Investment with Regulatory Certainty

What happened

In the 2026/27 fiscal year budget, Tanzania positioned mining as the core pillar of economic growth. The budget includes two important reforms: first, tax exemptions approved by the cabinet in framework agreements will no longer require additional government announcements to take effect, thus reducing regulatory uncertainty; second, 10% of total mineral revenue will be allocated to the Mineral Research Fund to enhance geological knowledge, exploration capacity, and technical support.

The logic behind the development

The global critical mineral supply chain is highly dependent on China (which controls 90% of processing and refining capacity), and governments and investors are actively seeking alternative sources. Tanzania has abundant mineral reserves, with critical minerals accounting for about 50%-55% of its total export value, making it the largest mining economy in East Africa. However, resource nationalism policies over the past decade have suppressed investment. This reform marks a strategic shift from resource nationalism to attracting investment through regulatory certainty.

Significance for local development

• Employment and industrialization: Mining is the third-largest industry, and the reform will attract more large-scale mine investments, creating direct employment. At the same time, the Mineral Research Fund will help small-scale miners (contributing about 40% of mineral revenue) improve productivity and modernization, benefiting thousands of workers.
• Energy and infrastructure: Stable mining revenue can provide fiscal support for infrastructure such as power grids and roads.
• Industrial upgrading: Downstream value addition (such as processing and refining) will increase product value and reduce dependence on raw material exports.

Impact on regional development

• Comparison with neighboring strategies: The Democratic Republic of the Congo (DRC) controls cobalt supply through export quotas, while Tanzania focuses on improving the investment environment. This differentiated competition may attract more international capital to Tanzania and promote the integration of the East African mining value chain.
• Regional connectivity: Tanzania's ports (such as Dar es Salaam) and railway networks will benefit from increased mineral exports, strengthening trade ties with neighboring countries (such as Zambia and the DRC).
• Enhancing regional competitiveness: If Tanzania can establish a stable mineral processing center, it will strengthen East Africa's position in the global critical mineral supply chain.

Potential impacts over the next 5 to 15 years

• Changing the industrial landscape: If the reforms are effectively implemented, Tanzania could become a globally important supplier of critical minerals such as lithium and rare earths, attracting the localization of battery and electric vehicle supply chains.
• New engine of economic growth: Mining growth will drive services, logistics, and manufacturing, pushing GDP growth beyond the 6.3% target.
• Shifts in investment flows: As regulatory certainty improves, more long-term capital is expected to flow from high-risk regions like the DRC to Tanzania.

ConclusionTanzania’s reforms represent an important attempt by African resource‑based countries to shift from resource nationalism to institutional competition. If implemented effectively, it could become a key node in the story of African mining investment and industrialization over the next decade—proving that regulatory predictability itself is a core competitiveness.
