Gold ETFs vs Gold Futures: Costs, Exposure and Risks

Two ways to hold the same metal

A gold ETF and a gold future both rise when gold rises. That is where the similarity ends.

An ETF share is a claim on a trust. The trust owns bullion, a custodian stores it, and the fund’s NAV is the value of that bullion divided by the shares outstanding, less accrued expenses. The share trades on an exchange and can move away from NAV.

A futures contract is an agreement to buy or sell a fixed quantity at a fixed date. The COMEX gold contract is 100 troy ounces, quoted in dollars per ounce, with a minimum tick of $0.10 — $10 per contract. It expires, it can be settled by delivery, and if the holder wants exposure beyond the expiry, the contract must be rolled.

Neither instrument is “gold” in the sense of a bar in a safe. The difference is the wrapper, and the wrapper determines the cost and the risks.

The ETF: an annual fee and a share price

Physically backed gold ETFs are straightforward. GLD, the largest, charges a gross expense ratio of 0.40% and held gold through HSBC and JPMorgan as custodians. IAU charges a sponsor fee of 0.25% and held 14,883,534.15 ounces — 462.93 tonnes — in trust as of 16 October 2026.

The fee is charged by reducing the trust’s gold over time, so the NAV drifts down relative to the metal by roughly the expense ratio each year. That is the whole cost of the wrapper, and it is visible and annual.

The share price is a second variable. On 16 October 2026:

Both traded at a discount, which means a buyer paid slightly less than the value of the underlying gold. That is favourable on entry and unfavourable on exit if the discount persists or widens. The discount is usually small, but it is not zero, and in stressed markets it can widen. A holder who needs liquidity at that moment sells at the market price, not at NAV.

The ETF structure also introduces the custodian. The trust’s gold is held by a bank, not by the investor, and the claim is against the trust. That is a different risk from holding a bar, even though the economic exposure is the same.

The future: a dated claim and a curve

The COMEX gold future is a contract for 100 troy ounces. At the front-month price on 19 October 2026, 4,187.30 per ounce, one contract has a notional value of 418,730. The tick is $10, so the price moves in $10 steps per contract.

The contract does not last forever. Each month has its own expiry, and the prices of different months form a curve. On 19 October 2026 the curve looked like this:

Later delivery costs more. That is contango, and the December-to-February step is 40.3 per ounce, or 0.96% of the December price, over roughly two months. On an annualised basis that is a little under 6% — close to the financing cost the market charges for deferring payment, plus storage and insurance.

The step is not a fee the exchange collects. It is the price of time. A trader who buys December and rolls to February pays it, but a trader who funds the position with cash earns interest on that cash over the same period. The two roughly offset when rates are the reference. The comparison changes completely when the futures position is leveraged and the cash is not there to earn.

Comparing the cost of a holding period

Take one contract’s worth of exposure: 100 ounces, about 419,200 of notional at the December price. The equivalent in GLD shares at 382.01 is about 1,097 shares, and in IAU shares at 78.34 about 5,351.

Over one year, the ETF wrapper costs:

• GLD: 0.40% of 419,200 = 1,676.80
• IAU: 0.25% of 419,200 = 1,048.00

The futures wrapper costs the roll. If the curve stayed at the December-to-February step, rolling one contract would cost about 4,030 per two-month roll — six rolls a year, roughly 24,180, or 5.8% of notional. That is much more than the ETF fee.

But that comparison is incomplete in the direction that matters. The futures holder is not paying 5.8% to hold gold; they are paying the financing embedded in the curve while holding cash that earns a similar rate. If the cash collateral earns 5%, the net cost of the roll is a fraction of a percent — closer to the ETF fee, and in some rate environments below it. If the position is leveraged and the cash is not earning, the roll is a real cost that compounds.

So the correct question is not “which is cheaper” but “which is cheaper for this funding arrangement and this holding period”. A cash-funded futures position and a leveraged one have different economics even though the contract is the same.

Leverage, margin and the shape of the risk

An ETF share is bought for its full price, or on margin through a broker under that broker’s rules. A futures contract is opened by posting initial margin, a performance bond that is typically a small fraction of the notional. The rest is not borrowed in the way a margin loan is; it is the leverage inherent in the contract.

That leverage has a consequence the ETF does not: daily settlement. A futures account is marked to market every day, and losses are debited from the margin balance. A move that would leave an ETF holder down on paper can force a futures holder to post more margin or close the position. The liquidation mechanics — and the difference between the liquidation price and the bankruptcy price — are covered in liquidation price vs bankruptcy price.

The ETF has no such mechanism. A 20% fall in gold leaves the share down 20%; there is no margin call and no forced sale. That is a genuine difference in the risk of ruin, not just in the cost.

Tracking, delivery and the things that differ

What the ETF tracks. The trust’s NAV tracks the gold price less expenses. It does not track a futures curve and does not roll. Over long periods the ETF’s return is the metal’s return minus the fee, plus or minus the premium or discount at entry and exit.

What the future tracks. The front-month contract converges to spot at expiry, but a rolled position does not track spot over time. In contango, rolling repeatedly produces a return below spot; in backwardation, above it. A futures-based gold strategy can therefore lag the metal even when the metal rises.

Delivery. COMEX gold is physically settled, with delivery of 100 troy ounces at a minimum fineness of 995. Most holders close before expiry rather than deliver, but the option exists, and it is the reason the contract’s final settlement converges to the physical market.

Custody. The ETF’s gold is held by a custodian; the futures position is a claim on the clearinghouse. Neither is a bar in a private vault, and both depend on an institution.

Which instrument fits which purpose

• Long holding period, no leverage, simple accounting: the ETF. The cost is the expense ratio, the tracking is direct, and there are no rolls.
• Short-term directional trade: futures, because the contract is liquid, trades nearly around the clock, and requires only margin.
• Hedge with a defined horizon: futures, because the expiry can be matched to the exposure and the position can be closed at a known date.
• Curve or spread trade: futures, because there is a curve to trade and the ETF has no equivalent.
• Taxable account with a long horizon: compare the after-tax treatment, not just the expense ratio. In the United States the two are taxed differently, and the difference can exceed the fee gap.

Whichever is chosen, the number to compare is the all-in cost of the intended holding period, not the headline expense ratio or the front-month price.

Risk note. Fund data in this article were read from the issuers’ pages on 2026-10-19, prices from exchange data for 2026-10-16 and 2026-10-19, and contract specifications from CME Group. ETF premiums and discounts, futures curves and expense ratios change. Futures are leveraged and can lose more than the initial margin; ETFs can trade below NAV. Nothing here is investment advice or a tax recommendation.

The wrapper is the decision

The metal is the same. The difference is the wrapper: an annual fee and a share price that can drift from NAV, or a dated contract with a curve, a roll and daily settlement.

For a long hold, the ETF’s 0.25%–0.40% is the cost of not having to think about expiry. For a trade or a hedge, the future’s leverage and precision are the point, and the roll is the price of extending it. Choosing between them is not a question about gold. It is a question about how long the position will exist and how it will be funded.
