Commodity ETFs and ETCs: what is the difference?

The short answer

You can get commodity exposure through both UCITS ETFs and exchange-traded commodities, or ETCs.

A commodity UCITS ETF is a regulated investment fund. It may track a diversified commodity index using financial contracts.

An ETC is normally a debt security issued by a company. It may provide exposure to a single commodity, such as gold, or a basket of commodities.

Other ETFs own shares in commodity-producing companies. That is different from tracking commodity prices.

Why it matters

Products with similar names can give you different investments and investor rights.

Commodity-index ETFs

These funds provide exposure to a basket of commodities, such as energy, metals and agricultural products. They may use swaps—contracts with a financial institution—to obtain the return of an index based on commodity futures.

Examples include the iShares Diversified Commodity Swap UCITS ETF and the Invesco Bloomberg Commodity UCITS ETF.

ETCs

A physically backed gold ETC holds metal within its structure. Other ETCs use financial contracts to provide commodity exposure.

You own a security with rights set out in the product’s legal documents. You do not own units in a UCITS fund or necessarily own the commodity directly.

Many physically backed ETCs are secured: specified assets support investors’ claims. This can provide protection, but recovery following a default may still involve delays, costs or losses.

“Debt security” describes the legal structure. It does not mean the ETC pays regular interest or guarantees repayment of your original investment.

Commodity-company ETFs

A gold-mining ETF owns shares in mining companies. Its return depends on factors such as production costs, management and company profits, as well as gold prices.

Mining shares can fall even when gold rises.

A simple example

Three investments mention gold:

• A broad commodity UCITS ETF includes gold alongside other commodities.
• A physically backed gold ETC provides exposure to gold held within its structure.
• A gold-mining UCITS ETF owns shares in companies that mine gold.

They are three different investments. Their prices need not move together.

For products using futures, replacing expiring contracts can also affect returns. A product may lose value even when the current commodity price is unchanged.

What to check

• Is it a UCITS ETF, an ETC or another exchange-traded product?
• Does it track commodities or own shares in commodity companies?
• Is the exposure to one commodity or a diversified basket?
• Does it hold physical commodities or use financial contracts?
• Who is the issuer, and what rights do investors have?
• Which assets support any secured claims?
• What fees, currency risks and futures-replacement costs apply?

Key term explained

A futures contract is an agreement to buy or sell an asset at a future date on specified terms.

A commodity futures index tracks these contracts. Its return can differ from changes in the spot price—the price for immediate delivery.

Understand both the exposure and the legal structure before comparing products.
