This guide compares commodity ETFs by return structure, volatility, and annual cost. Physical gold funds track bullion prices less expenses, while futures-based baskets can trail spot prices and yearly fees span 0.10% to about 0.85%. A commodity ETF is an exchange-traded fund that tracks raw materials through metal bars or futures contracts. Fee drag compounds for long-term holders, roll mechanics shape futures returns, and sharp price swings affect position size.

What do gold ETFs cost to hold?
State Street Global Advisors reports that SPDR Gold Shares (GLD) charges a 0.40% gross expense ratio, or $40 per year on $10,000, with returns reduced because the trust sells bullion to pay expenses GLD fund page. That structure links cost directly to performance: higher bullion sales for fees mean less metal backing each share over time. Buy-and-hold investors pay that drag every year they own the fund.
State Street Global Advisors fund finder lists SPDR Gold MiniShares (GLDM) at 0.10% versus 0.40% for GLD, giving long-term holders materially lower recurring drag for the same bullion exposure fund finder comparison. State Street says GLD aims to reflect gold bullion performance less trust expenses against the LBMA Gold Price PM benchmark. Its holdings are allocated London vault bars, so the choice is mainly fee level rather than different metal exposure.
What do broad commodity baskets cost?
Invesco US lists its PDBC diversified commodity ETF at a 0.67% total expense ratio and 0.59% net expense ratio after waivers, below its older DBC sister fund at about 0.85% net commodity investing page. PortfolioMetrics reporting BlackRock data shows the same pattern elsewhere: GSG commodity trust charges 0.75% while COMT dynamic-roll ETF charges 0.48%. Newer broad-basket designs often cost less annually than older index-linked pools.
The practical difference is recurring. A 0.59% net fee takes $59 per year on $10,000, while a 0.85% fee takes about $85. Over several years, that gap matters more when commodity spot returns are modest or uneven.
Why do returns trail spot prices?
Futures-based funds must sell expiring contracts and buy later-dated ones to stay exposed. The U.S. SEC NYSE Arca filing notice explains that in contango the new contract costs more than the expiring one, creating persistent roll losses and underperformance versus spot prices SEC filing notice.
A rising commodity index can therefore still leave a futures fund flat or down. Physical gold funds avoid futures roll but still lag bullion because expenses come from holdings. State Street disclosures describe the trust selling small amounts of gold to cover fees. Investors should compare a fund against its benchmark after fees, not against the spot headline alone.
How should volatility shape position size?
Financial Advisor Magazine reporting on futures-based ETFs describes commodity prices as highly volatile and sensitive to geopolitics, supply disruptions, weather, inflation, and dollar strength. That mix makes sharp gains and losses normal, especially in energy and agriculture-heavy baskets.
Commodity ETFs therefore suit mainly supplemental allocations rather than core holdings. State Street and SEC-filed GLD disclosure notes the limitation that past ETF and index performance does not guarantee future results, and investment return and principal fluctuate so investors may gain or lose when selling shares.
- Decide the role first: inflation diversification or tactical exposure, not steady income.
- Size the position so a 20-30% drawdown does not disrupt spending or rebalancing plans.
- Check structure: physical bullion for metal exposure, futures basket for broad materials.
- Compare net expense ratio, roll method, and benchmark before choosing between sister funds.
