Gold Spot and Futures: Understanding Basis

A price comparison starts with the label

One screen shows spot gold and another shows a futures contract. The numbers differ, and a trader assumes that one feed must be wrong. The first question is simpler: are the screens describing the same thing? Identify the instrument, currency, unit, quoted side and timestamp. For futures, include the contract month. A comparison between an indicative spot price and a different contract’s last trade can contain several differences at once. Identify the Contract Before Counting Ticks explains why the label belongs in the calculation rather than in a footnote added after a decision.

Give the price difference a name and a direction

CME describes basis as the difference between a commodity futures price and its underlying physical spot price, using futures minus spot in its example.^[1] Suppose, purely for arithmetic, a spot quote is 2,500 and a futures quote is 2,520 dollars per ounce at the same observation time. Under that convention the basis is positive 20 dollars per ounce. These are invented values, not current prices. Write the subtraction convention beside the result, since a bare number does not tell a reader which series was subtracted. It also does not establish an executable opportunity.

Do not turn a comparison into a free-profit story

The CME discussion identifies time value of money and costs associated with physical gold among the considerations in futures pricing.^[1] A visible difference therefore needs interpretation; it is not automatically an error available for anyone to capture. Before calling a discrepancy tradable, examine which prices are executable, the costs and the obligations of each leg. This article does not provide an arbitrage strategy. Gold Trading Costs adds the execution question. The Expiry Date Belongs in the Plan explains why a futures label includes a time commitment that a generic gold headline can hide.

Preserve the comparison you actually made

Save a small record: source, instrument, contract month, unit, timestamp and subtraction convention. If the spread changes, compare the same pair of series again rather than silently switching to the next futures contract. Record any change in the method.

The Gold Trader’s Code continues the theme of explicit trading rules. Understanding basis can improve the question asked of two prices; it does not forecast their next move or make a position suitable for a particular reader.
