Commodity prices and the investment you actually own

Follow the contract or asset behind the commodity label before comparing its return with a spot-price headline.

Delivery date, location and grade belong to the price.

Spot concerns immediate delivery; futures specify later delivery or settlement. Storage, finance, insurance and the value of usable inventory help explain differences between dates.

Two invented snapshots on one observation date. Same good, grade, location and quote units; alternative curves, not forecasts.

Contango

Spot 100 → near 105 → later 110

Backwardation

Spot 100 → near 95 → later 90

Horizontal: delivery or settlement date →
Vertical: quote, same scale (90–110 points shown).

Later contracts are priced now. Their current premium or discount does not reveal the price at which you will close them.

Futures can change while the matching spot price stays unchanged.

Unchanged spot does not prevent a futures loss.

Invented fund: €11,000 cash backs €11,000 initial long futures notional. Futures quote 110 falls to 100; matching spot starts and ends at 100. Fixed position, no cash interest, fees, tax, flows or other positions. Collateral needs assumed met throughout.

Initial observation

Same contract: 110
Matching spot: 100

Later observation

Same contract: 100
Matching spot: 100

Time passes → two observations, no daily path assumed.

Initial cash €11,000

Remaining cash €10,000; settlement loss €1,000

€0€11,000

About 9.09% of initial notional lost (hatched): 10 ÷ 110 × €11,000.

The quote was not an €11,000 purchase bill. The later price move causes the loss; the initial premium need not decline.

Settlement and the ability to maintain the position

CME describes settlement movements; this does not establish that an actual position could maintain its margin balance. See capital and margin separately.

The roll gap is not an invoice.

Ongoing exposure generally replaces expiring contracts. Rules and the changing curve affect returns, but “roll yield” is not a fee equal to the full gap on replacement day. Later prices, exposure maintained and index calculation matter; trading charges are separate.

Contango cannot guarantee a negative total return; backwardation cannot guarantee a positive one. Check how the benchmark treats collateral income, expenses and contract replacement. For a series labelled price, excess-return or total-return, read its methodology before comparing it with a spot-only chart. The label alone does not establish which cash flows are included.

A long holdings list can share one demand shock.

Inspect weights, concentration and leverage permissions, then compare implementation with the proposed inflation/diversification role. Common supply or demand shocks can hurt several commodities together. Historical help gives no timely protection when other holdings fall or your spending costs rise.

Spot and a fund result

A commodity's matching spot price starts and ends at 100, but a futures-based product loses money. Is that necessarily a tracking failure?

  • Yes; unchanged spot requires a zero contract return before the product’s published fees.
  • No; the initial futures-versus-spot gap alone fixes the loss regardless of subsequent prices.
  • No; the intended exposure may be futures, with a different price path, contract maintenance, collateral income and costs.
Show the explanation

Correct answer: No; the intended exposure may be futures, with a different price path, contract maintenance, collateral income and costs.

A futures-based mandate is not a promise to replicate a spot quote. Contract returns and the maintained exposure can differ from spot, while collateral income and expenses affect the whole result. Evaluate tracking against the product's actual stated benchmark and return definition.

Two contract dates

Later-dated futures are currently more expensive than near-dated contracts. What does that observation establish?

  • An upward-sloping curve, without guaranteeing the investment's eventual total return.
  • A certain negative return equal to the current contract-price gap.
  • A separate cash fee automatically charged for the full gap on the roll date.
Show the explanation

Correct answer: An upward-sloping curve, without guaranteeing the investment's eventual total return.

This is commonly called contango. It describes current prices, while subsequent changes and the exposure maintained determine investment gains and losses. Trading expenses are separate. A curve observation is neither a complete return forecast nor an invoice for its full price gap.
