Exchange-traded funds have long given investors convenient access to some of the world’s most valuable commodities, primarily gold and silver. Both metals dominated headlines amid what many market participants call the “debasement trade.” Major gains for gold ETFs and silver ETFs in 2025 reflect rapidly rising interest from investors, traders and speculators.
The debasement trade reflects a view that persistent fiscal deficits, heavy government borrowing and accommodative monetary policy will erode the purchasing power of the U.S. dollar over time, pushing investors toward hard assets perceived as resistant to inflation and currency dilution.
Historically, gold has been a primary beneficiary of this mindset. It remains a core component of central bank reserves worldwide and has functioned as a store of value across cultures and monetary regimes. Silver, while also considered a precious metal, draws additional support from its industrial uses.

But gold and silver are not the only metals attracting investor interest. Another metal gaining momentum is copper. It may not carry the same mystique as gold or silver, yet its role in the modern economy is arguably more critical. And precious metals ETFs provide some industrial exposure.
As global electrification accelerates in the age of artificial intelligence (AI), though, copper increasingly looks less like a cyclical industrial input and more like a structural growth story. That theme was underscored by a January 2026 report from S&P Global, “Copper in the Age of AI: Challenges of Electrification.”
The firm highlighted several noteworthy trends. Most notably, the U.S. government designated copper a critical mineral in 2025 due to its importance in mobility infrastructure, communications networks and defense tech.

Meanwhile, global copper demand is projected to rise from 28 million metric tons in 2025 to 42 million metric tons by 2040, a roughly 50% increase. At the same time, analysts forecast a potential 10 million metric ton supply shortfall by 2040 if new production fails to keep pace.
Copper’s investment case is about long-term, upstream exposure to the raw material layer of industries such as AI data centers, electric vehicles, grid upgrades and renewable energy buildouts.
Copper ETFs offer brokerage-accessible ways to express that view, but can vary meaningfully in exposure. Here’s our breakdown of five copper ETFs worth considering and what differentiates them from one another.
How we defined copper ETFs
Not all copper funds are structured the same way. In fact, some aren’t even ETFs. A good example is the Sprott Physical Copper Trust (COP).
It’s a closed-end fund (CEF). Unlike ETFs, which create and redeem shares on an ongoing basis to keep supply aligned with demand, CEFs launch through an initial public offering (IPO) with a fixed number of shares. After that, shares simply trade between investors on the exchange.
That structure leads to an unusual dynamic. A CEF’s market price can trade above its net asset value (NAV), known as a premium, or below it, known as a discount. Depending on buying and selling pressure, you could end up overpaying or underpaying relative to the value of the underlying assets.
For example, as of February 17, COP’s NAV was $11.60 while its market price was $11.39. That means investors were buying its underlying copper reserves at roughly a 1.8% discount.

And there’s no guarantee a discount will narrow. It can persist for years, or even widen. On top of that, COP carries a 1.61% expense ratio, which is relatively high.
Unlike gold, there is currently no widely available U.S.-listed ETF that holds physical copper bullion in vaults. Instead, most copper ETFs focus on copper mining companies.
These are companies that explore for deposits, drill and extract ore from the ground, process it and sell refined copper into the market. What makes or breaks these companies often comes down to their “all-in sustaining cost,” or AISC. This represents the total cost of producing one pound of copper, including extraction, labor, energy, and maintenance.
When copper prices rise meaningfully above a miner’s AISC, profit margins expand rapidly. When prices fall toward or below that cost level, margins compress or disappear.

A miner’s fixed costs remain largely the same regardless of copper prices. So when revenue per pound increases, a large portion of that incremental revenue flows straight to the bottom line. The reverse is also true in downturns.
That’s why copper mining stocks tend to be correlated with spot copper prices, but often in amplified fashion. As a result, copper miner ETFs can be more volatile than copper itself.
Copper mining ETFs are common because wrapping publicly traded mining stocks inside an ETF is straightforward. Investors get indirect copper exposure without dealing with the hassle of CEFs.
For the majority of long-term investors interested in copper as a structural theme tied to electrification, a copper mining ETF often strikes a balance between accessibility, liquidity and exposure.
How we picked the best copper ETFs
In addition to excluding copper CEFs, we also omitted several types of copper exposure that, in our view, introduce unnecessary complexity or structural risk for long-term investors.
First, we excluded leveraged copper ETFs. These are the funds with “2x” in the name that aim to deliver two times the daily return of a copper benchmark. The emphasis is on daily price action.
Because these ETFs reset each day, performance over longer holding periods can diverge significantly from simply doubling copper’s long-term return, especially in volatile markets. The compounding effect can work against investors, making these vehicles more suitable for short-term trading.
Second, we excluded futures-based copper ETFs. These funds hold copper futures contracts rather than physical copper or copper mining stocks. Futures prices are not always aligned with the current, or spot, price of copper. And the gap between the two can materially impact returns.
A key risk is “contango,” where longer-dated futures trade at higher prices than near-term contracts or the spot market. When contracts approach expiration, the ETF must sell the expiring contract and buy the next one. In a contango environment, that often means selling lower and buying higher, creating a persistent drag on performance.

Many futures-based commodity ETFs are also structured as limited partnerships. Investors may receive a Schedule K-1 instead of a standard Form 1099. A K-1 can complicate tax filing, potentially involving additional forms, multi-state reporting, and delayed tax documents.
Because the copper ETF universe is relatively narrow, we were less rigid on fund size and expense ratios than in other categories. That said, we still flagged cases where lower assets under management could pose a potential risk of closure or where fees were meaningfully higher than the category average.
Finally, we focused heavily on explaining benchmark construction and geographic exposure. Some copper ETFs track global mining indexes, while others tilt toward specific regions such as Canada, Australia or emerging markets.
Differences in benchmark methodology, weighting schemes and geographic concentration can meaningfully affect investment outcomes. Those structural distinctions are often more important than small differences in fees.
Global X Copper Miners ETF
(Image credit: Getty Images)
- Inception date: April 19, 2010
- Expense ratio: 0.65%
- Assets under management: $7.46 billion
- 30-day median bid-ask spread: 0.09%
The Global X Copper Miners ETF (COPX) is the largest copper-focused ETF by assets under management, a status it has earned largely through longevity. With more than a decade of live performance history, COPX has become the default choice for many investors seeking pure-play exposure to copper mining equities.
The fund tracks the Solactive Global Copper Miners Total Return Index, which currently includes 41 companies. Holdings are concentrated in the materials sector, since that is where miners are classified.
Unlike broad equity ETFs that are typically overweight the U.S., COPX has a distinctly global footprint. Canada represents the largest country allocation at 36.7%, reflecting the country’s deep mining ecosystem, established regulatory framework and large number of publicly listed resource companies. China, the U.S., Australia and Japan round out the top country exposures.
Performance has been robust, particularly in recent periods. Over the trailing 10-year period, COPX has delivered a 22.17% annualized total return with distributions reinvested. A significant portion of that gain has come more recently, with the ETF up 93% over the past year as copper prices rallied sharply.

iShares Copper and Metals Mining ETF

- Inception date: June 21, 2023
- Expense ratio: 0.47%
- Assets under management: $446.81 million
- 30-day median bid-ask spread: 0.18%
The iShares Copper and Metals Mining ETF (ICOP) comes from BlackRock’s expansive iShares lineup, which offers ETFs across virtually every asset class and strategy. Despite launching only in mid-2023, ICOP has gathered meaningful assets, reflecting the strength of the iShares brand.
The ETF tracks the STOXX Global Copper and Metals Mining Index, a benchmark composed of 47 companies. Canada represents a significant portion of the portfolio.
But ICOP differs from COPX in that it casts a wider net across diversified metals miners rather than focusing on pure-play copper producers. As a result, you see relatively greater representation from companies based in the United Kingdom and Australia, along with firms that derive revenue from multiple industrial metals in addition to copper.
Liquidity is lower than COPX, with a bid-ask spread roughly twice as wide. However, investors benefit from a lower expense ratio.

Sprott Copper Miners ETF

- Inception date: March 5, 2024
- Expense ratio: 0.65%
- Assets under management: $283.7 million
- 30-day median bid-ask spread: 0.33%
While we were critical of Sprott’s physically backed copper trust due to its closed-end structure and premium-discount dynamics, the firm does offer a more conventional alternative in the form of the Sprott Copper Miners ETF (COPP).
COPP tracks the Nasdaq Sprott Copper Miners Index. Unlike ICOP, this benchmark places greater emphasis on pure-play copper producers. The portfolio currently holds 62 companies, and Sprott provides detailed breakdowns of revenue exposure and portfolio composition.
Geographically, the allocation is again Canada-heavy at approximately 43% of the portfolio, reflecting the country’s deep mining ecosystem. The U.S. follows, with Chile No. 3. Chile’s inclusion is notable, as the emerging market is one of the largest copper-producing nations.
COPP tilts toward larger companies, with about 70% of holdings above $10 billion in market cap. One distinctive feature of COPP is that it includes a small allocation, approximately 4.39%, to physical copper through ownership of Sprott’s physical copper trust.

Sprott Junior Copper Miners ETF

- Inception date: February 1, 2023
- Expense ratio: 0.76%
- Assets under management: $184.98 million
- 30-day median bid-ask spread: 0.43%
A junior miner is a company still in the exploration or early development phase. Many are not yet producing copper at commercial scale. Instead, they’re drilling, conducting feasibility studies, securing permits and attempting to prove out economically viable reserves.
Because their revenue is often limited or nonexistent, their valuations are highly sensitive to exploration results, capital market conditions and commodity price expectations. The upside can be significant if a project moves into production or becomes an acquisition target. The downside can be equally severe if financing dries up or resource estimates disappoint.
The composition of the Sprott Junior Copper Miners ETF (COPJ) portfolio reflects this speculative tilt: 78.1% of holdings are small-cap stocks with market capitalizations under $2 billion. Canada remains the largest country allocation. Australia, another jurisdiction known for its early-stage resource firms, ranks second at 15.2%.
Investors should understand that COPJ carries materially higher volatility than larger-cap copper miner ETFs such as COPP. The fund is also more expensive and less liquid, as reflected in its higher expense ratio and wider bid-ask spread.

- Inception date: September 24, 2024
- Expense ratio: 0.35%
- Assets under management: $13.31 million
- 30-day median bid-ask spread: 0.49%
If fees are your primary consideration when selecting a copper miners ETF, the Themes Copper Miners ETF (COPA) stands out. COPA is the lowest-cost option on this list.
COPA tracks the BITA Global Copper Mining Select Index, a portfolio of 53 companies involved in copper mining. Like most funds in this segment, it’s heavily weighted toward materials stocks.
Canada represents the largest country allocation, reflecting the country’s deep mining ecosystem, followed by the U.S., the UK and Australia. From a market-cap perspective, the portfolio skews toward larger, more established producers.
With just $13.31 million in assets, it’s significantly smaller than many peers. Lower AUM and lighter trading volume have translated into a wider bid-ask spread compared with larger copper ETFs.
