A physical gold hedge: why matching ounces can still leave a loss

Define the price that needs protection

CME’s gold hedging case study defines basis as futures price minus the underlying spot price. This article keeps that sign convention throughout. The CFTC glossary describes basis risk as uncertainty about the change in that relationship between opening and lifting a hedge. Those definitions provide the starting point, not evidence that a particular hedge will work.

My question is what a bullion owner actually wants to stabilize: a benchmark valuation, a dealer’s net buyback offer, or a future contracted sale. The three can differ. A hedge calculation that starts with the wrong cash price may be mathematically tidy while protecting something other than the owner’s economic exposure.

Match quantities in a transparent hypothetical

Assume an invented holding of 1,000 fine troy ounces. Its chosen cash reference is initially $4,000 per ounce and a selected futures contract is $4,020. Suppose the owner sells futures representing exactly 1,000 ounces. These are hypothetical prices and quantities; they are not a transaction recommendation, live quotation or historical trade.

Later the cash reference falls to $3,950 while the futures price falls to $3,980. The physical reference loses $50 per ounce, or $50,000. The short futures gain $40 per ounce, or $40,000. Together they lose $10,000 before costs. Equal ounces offset the common direction only to the extent that the two prices move together.

The residual is the change in basis

Under the stated convention, initial basis is $4,020 minus $4,000, or $20. Final basis is $3,980 minus $3,950, or $30. It widens by $10. For equal quantities, the change in cash value plus the gain on a short futures position equals minus the quantity multiplied by the change in basis. Here that is −1,000 × $10 = −$10,000.

Keep the sign visible. If final futures were instead $3,960 while cash remained $3,950, basis would narrow to $10. The combined result would be a $10,000 gain before costs. These two invented cases demonstrate why the residual cannot be assigned a favourable sign in advance. They do not estimate how often either outcome occurs.

The dealer’s price adds another layer

Suppose the physical item initially has a net dealer buyback reference $5 per ounce below the chosen spot benchmark. At disposal, imagine that deduction has grown to $12. The extra $7 reduction would worsen the result by another $7,000 on the same 1,000 ounces, assuming all other inputs unchanged. This is a separate hypothetical local-price effect, additional to the $10,000 basis loss above.

That exercise is why I would preserve both a global reference and a product-specific sale quotation. Matching a futures benchmark does not automatically match fabrication value, local availability, assay deductions or the amount a particular buyer will pay. The Dubai guide addresses purchase and buyback comparisons; this article adds the distinct question of how a derivative overlay interacts with those quotations.

A date mismatch can change the exposure after the hedge is opened

CME’s discussion of cross-market gold spreads explains that location and timing are relevant to the difference between physical and futures prices. For an actual project I would record the expected physical sale date, the chosen futures month and the rule for handling a delayed sale. A matched quantity on the opening day does not settle those later decisions.

If a hypothetical sale is postponed after the hedge is closed, the inventory becomes exposed again. If only half the inventory is sold but the entire short position remains, the remaining futures exposure may exceed the unsold metal. Updating the inventory schedule is therefore part of the hedge calculation. The useful unit of review is the combined position through time, not the initial contract count.

Measure effectiveness against the original objective

My proposed review contains four separate amounts: physical proceeds or valuation change, derivative profit or loss, financing and transaction costs, and the residual against the intended protected price. It also records whether the hedge was evaluated at an actual sale or merely marked on an intermediate date. Comparing different endpoints can manufacture an apparent success or failure.

A stable total value and a comfortable cash balance are also different objectives. Funding requirements can arrive before the physical sale generates cash, so the funding plan needs its own check. This article has verified no current hedge ratio, executable basis quotation or account result. Its contribution is a reproducible calculation that reveals what equal ounces do—and what remains to be measured.
