Sprott’s REXC ETF Puts Ex-China Rare Earth Investing in Focus as Supply Chain Concerns Rise
Sprott’s REXC ETF Puts Ex-China Rare Earth Investing in Focus
Sprott Rare Earths Ex-China ETF (REXC) is drawing attention as investors look for targeted exposure to rare earth companies outside China. The ETF seeks to track the Nasdaq Sprott Rare Earths Ex-China Index and focuses on companies involved in rare earth mining, exploration, development, separation, refining, and production. Sprott says the fund excludes Chinese securities and carries a net expense ratio of 0.65%.
Why Rare Earths Are Becoming a Bigger Market Story
Rare earth elements are used in many advanced technologies, including electric vehicles, wind turbines, robotics, electronics, aerospace systems, and high-performance magnets. Although they are called “rare,” the bigger challenge is not always finding them. The harder issue is building reliable mining, processing, refining, and magnet supply chains.
China remains a dominant force in rare earth processing and magnet production. Reuters reported in 2025 that China produces more than 90% of the world’s processed rare earths and rare earth magnets, while the United States has only one rare earth mine. This concentration has pushed governments and companies to search for alternative supply chains outside China.
What Makes REXC Different?
REXC is designed as a focused rare earth ETF with an “ex-China” approach. Instead of offering broad exposure to many strategic metals, the fund aims to give investors access to companies more directly tied to the rare earth value chain. According to Sprott, REXC seeks investment results that generally correspond to the total return performance of its underlying index before fees and expenses.
The ETF’s structure may appeal to investors who want exposure to companies outside China that could benefit from rising demand for rare earth supply security. However, it is still a specialized fund, meaning it may carry higher volatility than broader market ETFs.

Why Investors Are Watching Ex-China Supply Chains
The launch of REXC comes at a time when rare earths are increasingly viewed as strategic materials. They support clean energy, defense-related manufacturing, semiconductors, consumer electronics, and next-generation transportation. When one country controls a large part of processing, buyers may face supply risks, price swings, or delays.
That is why rare earth investing is no longer only a mining story. It is also a supply chain story. Investors are paying closer attention to companies that can mine, refine, separate, and produce rare earth materials in regions such as the United States, Australia, Canada, and Europe.
Important Risks to Consider
Although REXC offers a clear theme, investors should understand the risks. Rare earth companies can be affected by commodity price changes, permitting delays, political decisions, project financing issues, and global trade tensions. Smaller mining and development companies may also be more volatile than large established firms.
In addition, thematic ETFs can be concentrated in a narrow sector. This may create strong upside when the theme performs well, but it can also increase downside risk when market sentiment turns negative.
Outlook
REXC gives investors a new way to follow the rare earth supply chain outside China. Its launch reflects a larger trend: governments, manufacturers, and investors are trying to reduce dependence on one dominant supplier and build more resilient critical materials networks.
For investors interested in clean energy, advanced manufacturing, and strategic minerals, REXC may become an important ETF to watch. Still, because the fund focuses on a narrow and fast-moving sector, it should be reviewed carefully as part of a diversified investment plan.
