WIRE ETF review: Global X Copper Miners ETF (ASX, 2026)

WIRE is the ASX's largest green metals ETF by assets under management — $768 million as at 16 July 2026 — and the most focused. It holds 44 global copper mining companies, tracks the Solactive Global Copper Miners Total Return Index, charges 0.65% per annum, and returned 61.8% in the 12 months to July 2026.

That is WIRE in four numbers. The rest is context.

What WIRE holds

WIRE gives you a market-cap-weighted basket of copper miners from around the world. As at July 2026, the top five holdings are:

BHP Group Ltd — 5.6%
Teck Resources Class B — 5.3%
Antofagasta PLC — 5.2%
Southern Copper Corp — 5.1%
First Quantum Minerals — 5.1%

The remaining 39 holdings include Freeport-McMoRan, Lundin Mining, Capstone Copper, Hudbay Minerals, and a range of mid-cap and small-cap copper producers from Australia, Canada, Chile, Peru, the UK, and Poland. Geographic exposure spans the world's major copper mining jurisdictions, with no dominant single country concentration.

WIRE holds only copper miners — it has no exposure to lithium, nickel, cobalt, or rare earth companies. If those minerals are part of your investment thesis, WIRE does not cover them.

Fund stats (as at 16 July 2026)

Metric	Detail
ASX ticker	WIRE
Issuer	Global X ETFs Australia
Index tracked	Solactive Global Copper Miners Total Return Index

The 0.65% fee is the cheapest of the four green metals ETFs on the ASX — 4 basis points below XMET, GMTL, and ACDC, all at 0.69%. Over a decade, on a $50,000 position, that 0.04% difference saves roughly $500 — meaningful but not the primary decision factor.

The copper investment thesis

WIRE is a pure expression of a single thesis: copper prices will rise because electrification demands it.

The logic is straightforward. A single electric vehicle requires approximately 70kg of copper — more than three times what a conventional car uses. Every data centre, every solar installation, every grid upgrade requires copper wire and copper components. The IEA has projected a potential 30% shortfall in global copper supply by 2035 if new mines do not come online as needed.

On the supply side, copper ore grades are declining at existing mines, new large deposits are increasingly difficult to find, and permitting timelines for new mines run 10–20 years. The result is a structural case for elevated copper prices that is more straightforward than the lithium or nickel story — which are both more complicated by substitution risk and new supply.

BHP's own internal positioning says something: in the first half of FY2026, copper contributed 51% of BHP's underlying EBITDA for the first time, overtaking iron ore. The company's highest-conviction long-term commodity call is copper, and WIRE is a diversified basket of the companies BHP is competing with.

The case for WIRE

Largest and most liquid green metals ETF on the ASX. At $768M AUM, WIRE trades with tight bid-ask spreads and meaningful daily volume. For investors putting significant capital to work, liquidity matters.

Cheapest fee. 0.65% versus 0.69% for the alternatives is modest but real.

The cleanest copper thesis. If you want copper exposure, WIRE delivers it without dilution from other metals. If lithium or nickel are not part of your thesis, you are not being forced to own them.

Global diversification within copper. The 44 holdings span multiple jurisdictions, so a single regulatory problem, a strike, or a mine accident does not devastate the portfolio the way it would for a single-stock bet.

The case against

Only copper. This is also the fund's limitation. If the electrification boom drives demand for lithium or nickel more sharply than copper in a given cycle, WIRE misses it entirely. Investors who want the full green metals story should look at XMET alongside (or instead of) WIRE.

No Australian miner tilt. Despite Australia having the world's second-largest copper reserves, WIRE's holdings are globally distributed by market cap. Australian copper miners like BHP and OZ Minerals (now absorbed into BHP) are present, but Australia is not overweight relative to global copper production. Investors wanting explicit Australian copper exposure may need to supplement with individual stocks like Sandfire Resources (ASX: SFR).

Commodity cycle risk. WIRE's returns are driven by copper prices, and copper prices are cyclical. A supply glut or demand disappointment can reverse impressive 12-month returns quickly.

WIRE vs buying BHP or Sandfire directly

Some investors prefer to express the copper thesis through individual stocks rather than an ETF. The tradeoffs:

Approach	What you get	Main risk
WIRE ETF	44 miners, automatic diversification, low admin	No control over portfolio mix
BHP (ASX: BHP)	Copper + iron ore + potash, large-cap quality	Iron ore dilutes copper thesis
Sandfire (ASX: SFR)	Pure-play copper, MATSA + Motheo production	Single company risk, smaller scale

BHP is a natural comparison: it is WIRE's largest holding at 5.6%. Owning BHP directly gives you copper exposure, but also significant iron ore and diversified minerals exposure. If you want copper as your specific thesis, WIRE is more focused. If you trust BHP management to allocate capital well across a diversified commodity portfolio, BHP directly might suit better.

Who should buy WIRE?

WIRE suits investors who:

Have a specific view on copper prices and want clean, leveraged exposure
Want a diversified basket rather than single-stock risk
Value liquidity (the largest fund in the category)
Are comfortable with commodity cycle volatility
Do not need lithium, nickel, or cobalt in the same fund

It is less suited to investors who want broad green metals exposure across multiple minerals — XMET is a better fit for that. For a full four-way comparison, see our green metals ETF comparison guide.

Frequently asked questions

1. What is the WIRE ETF? WIRE is the Global X Copper Miners ETF, listed on the ASX. It holds 44 global copper mining companies, tracks the Solactive Global Copper Miners Total Return Index, and charges 0.65% per annum. With approximately $768 million in AUM as at July 2026, it is the largest green metals ETF on the ASX.

2. How has WIRE performed? WIRE returned 61.8% in the 12 months to July 2026, against a benchmark return of 63.5% — a tracking difference of approximately -1.7%. The gap reflects the fund's management fee and any transaction costs.

3. Does WIRE hold lithium stocks? No. WIRE holds only copper mining companies. It has no exposure to lithium, nickel, cobalt, or rare earth producers. For a broader green metals basket, XMET or ACDC are the alternatives to consider.

4. What is WIRE's management fee? WIRE charges 0.65% per annum, making it marginally the cheapest of the four ASX green metals ETFs. XMET, GMTL, and ACDC all charge 0.69%.

5. Is WIRE better than buying BHP directly for copper exposure? WIRE gives you 44 copper miners for the price of one trade, including BHP as its largest position. BHP directly gives you copper exposure alongside iron ore, potash, and other commodities. If your thesis is specifically about copper prices, WIRE is a cleaner expression. If you prefer BHP's management team and diversified commodity exposure, BHP directly may suit better.

6. Is there a newer copper ETF on the ASX? CPPR (ETFS Global Pure Play Copper Miners ETF) launched on the ASX in April 2026 as a competitor to WIRE. It is significantly smaller in AUM and has a shorter track record. WIRE's $768M in assets and 3.5-year history make it the more established choice at this stage.
