World’s rare earth giants: Top 10 countries with the biggest reserves

More countries are emerging as potential rare earth oxides (REO) suppliers, with upward revisions of estimates of available deposits in key countries outside China.

Latest data from the US Geological Survey points to upward adjustments for Australia’s reserves (from 5.7 million to 13.6 million tonnes) and Malaysia’s (to 0.71 million tonnes), citing official government data.

A renewed attention to reserve data comes at a time when countries are increasingly seeking to secure their own supplies of critical minerals.

The growing demand for electric vehicles, renewable energy technologies, defence and advanced electronics will likely intensify competition for rare earth elements (REE) in the coming years.

Policymakers in several regions are pushing to diversify supply chains and reduce dependence on a small number of producers.

Updates from the 2026 USGS Report

The USGS Mineral Commodity Summaries 2026, released in February, provides the most current estimates based on 2025 data, with notable revisions.

Besides Australia and Malaysia, India is also listed as a potential REE supplier.

In July, Indian government official Jitendra Singh, said India has identified a total of 8.52 million tonnes (MT) of in-situ REO resources across multiple states, though data remains unverified or reclassified data.

The world total reserves are estimated at over 85 million tonnes, a downward revision from prior figures, reflecting more refined assessments of economically recoverable deposits.

What are rare earth elements?

Rare earth elements include the 15 lanthanides (such as neodymium, dysprosium, and cerium), plus scandium and yttrium.

Despite their name, these elements are not particularly “rare” in the Earth’s crust — they are more abundant than silver or gold — but they are challenging to extract in economically viable concentrations due to their dispersed nature.

REEs are typically found in minerals like bastnasite, monazite, and xenotime.

Why do rare earth reserves matter?

REEs are critical for high-tech applications:

Electronics and Defense: Neodymium in permanent magnets for hard drives, electric motors, and wind turbines; europium in LED screens.

Green Energy: Essential for electric vehicle batteries, solar panels, and energy-efficient lighting.

Healthcare and Industry: Used in MRI machines, catalysts for petroleum refining, and alloys for aerospace.

Demand surging

Global demand is surging with the shift to renewable energy. The International Energy Agency projects that REE demand could quadruple by 2040 to meet net-zero goals.

Yet, production is highly concentrated, raising concerns about supply security, price volatility, and strategic vulnerabilities, as per National Defense Magazine.

Below is a bar chart ranking the top 10 countries by rare earth oxide (REO) reserves in 2024, sourced from USGS data.

Here’s a summary:

Global reserves are estimated at 130 to 160 million tonnes. This data underscored China’s overwhelming dominance, holding about one-third of known reserves, while the rest are distributed across diverse geographies, including emerging players like Brazil and Vietnam.

Reports are also emerging from DR Congo and the Philippines, with potential, but unquantified, REE deposits.

It’s a stark reminder of how reserves do not always translate to production— China dominates mining output as well.

Production data

Global mine production rose slightly from 380,000 tonnes in 2024 to 390,000 tonnes in 2025, with China accounting for about 70%, according to a USGS report.

The report notes that while REEs are abundant in the Earth’s crust, minable concentrations are scarce, and North American resources (beyond reserves) exceed 17 million tonnes.snexplores.org

Geopolitical and Economic Implications

China’s control over reserves and production gives it significant leverage.

In recent years, export restrictions on certain REEs have prompted responses from the West.

The US has invested in domestic sites like Mountain Pass in California, boosting output to 51,000 tonnes in 2025.

Australia, with its revised higher reserves, is expanding operations through companies like Lynas Rare Earths.

Diversification efforts include alliances like the US-EU Critical Minerals Agreement and investments in Africa and South America.

Challenges

However, challenges persist: Environmental regulations in developed nations slow development, while in places like Burma and Madagascar, production is rising but often lacks transparency.

Economically, REE prices fluctuate with demand from the EV sector. As of early 2026, neodymium prices have stabilized after a 2025 spike, but supply risks remain.

Rare earth mining is resource-intensive, producing toxic tailings and requiring vast amounts of water and energy.

Innovations like electrokinetic mining aim to reduce impacts, but the irony is clear: REEs enable green tech but come at an environmental cost.

Sustainable practices, recycling (currently under 1% of supply), and alternative materials research are crucial.

Looking ahead: Shifting landscape

The 2026 USGS updates reveal a shifting landscape with revised estimates and growing production outside China.

As demand escalates, balancing resource security, environmental stewardship, and international cooperation will be key.

Countries like Australia and Brazil could emerge as counterweights, but true diversification requires investment and innovation.
