Spot Gold vs. Gold Futures: Contract Specifications and Settlement Mechanics
Spot gold and gold futures diverge first at the level of contract design. Spot gold is not a single standardized exchange contract but a convention for immediate delivery: a trade executed today for settlement typically within two business days (T+2), quoted most famously in the London over-the-counter market and mirrored by exchange-traded products and retail CFD or leveraged spot products. Because it is OTC, spot gold carries no fixed contract size, no central clearinghouse mandate, and no expiration; participants negotiate lot sizes, credit terms, and settlement logistics bilaterally or through brokers. The benchmark price is set twice daily during the London bullion market’s AM and PM auctions, conducted in USD per troy ounce, with liquidity concentrated in the loco London vaulting system.
Gold futures are exchange-listed, standardized, and centrally cleared. The benchmark contract is COMEX Gold (ticker GC), representing 100 troy ounces of minimum 995 fineness, with delivery months spread across February, April, June, August, October, and December, plus serial months. The exchange sets tick size at $0.10 per ounce ($10 per contract), trading hours spanning nearly 24 hours a day Sunday through Friday, and delivery via approved depositories in New York. Position limits, margin requirements, and daily price limits are imposed by the exchange and clearinghouse. Mini contracts (33.2 troy ounces) and micro contracts (10 troy ounces) extend access to smaller accounts. The essential contrast: spot is a bespoke, immediately settled OTC market; futures are a regulated, standardized, deferred-settlement exchange market.
Pricing, Cost of Carry, and the Contango Question
The price relationship between spot and futures is governed by the cost of carry. A futures price equals the spot price plus financing costs (interest on the capital tied up in metal), storage and insurance, and any convenience yield subtracted. When rates and storage exceed convenience yield, futures trade above spot—contango—and the annualized gap is the basis. When physical demand spikes, convenience yield can invert the curve into backwardation, as happened episodically during the 2020 pandemic logistics disruption and again during the 2025 tariff-driven bullion flows into COMEX vaults, when New York futures traded at persistent premiums to London spot.
This basis is not academic. For a hedger, the roll yield embedded in contango is a real cost of maintaining a short futures hedge; for a carry trader, it is the return to financing physical metal against a short futures position. Spot prices, by contrast, embed no time value—they reflect immediate supply-demand and the financing cost is borne directly by the holder. Traders monitoring the spread watch the futures-spot basis, the EFP (exchange for physical) spread, and the gold lease rate, which reflects the cost of borrowing metal and can signal physical tightness before it appears in the outright price.
Leverage, Margin, and the Cost of Holding a Position
Leverage differs structurally. A futures position requires initial margin—historically a few percent of notional, set by the exchange and adjusted for volatility—and is marked to market daily, with variation margin flowing in and out of the account. Spot gold bought outright involves full payment; leveraged spot products (CFDs, retail spot contracts) offer margin trading but at broker-determined rates, often with financing charges applied nightly to the notional exposure. The holding-cost profile therefore inverts: futures embed financing in the contract price and require ongoing margin management; unleveraged spot embeds storage and insurance for allocators who take delivery, while leveraged spot embeds daily financing debits.
Settlement, Delivery, and Counterparty Risk
Settlement mechanics carry distinct risk profiles. Futures are novated to a clearinghouse, which interposes itself between buyer and seller and guarantees performance; credit risk is mutualized through the clearing member structure and margin fund. Delivery, when it occurs, follows exchange rules: vault receipts, approved refiners, and defined delivery dates. The overwhelming majority of futures positions are closed or rolled before delivery, so the contract functions as a price exposure vehicle rather than a metal acquisition channel.
Spot gold in the London OTC market settles through unallocated accounts—book entries representing a claim on a pooled pool of metal—where counterparty exposure to the bullion bank or broker exists until metal is allocated. Allocation converts the claim into title over specific bars, eliminating the credit component but introducing storage and insurance costs. Retail leveraged spot products typically never involve physical settlement at all; they are cash-settled contracts with the broker as counterparty, meaning the trader bears broker credit risk, mitigated in regulated jurisdictions by client money segregation. The practical upshot: futures offer clearinghouse-backed credit quality with delivery optionality; OTC spot offers flexible settlement and allocable metal at the price of bilateral credit assessment.
Liquidity, Trading Hours, and Market Microstructure
Liquidity is deep in both markets but structured differently. COMEX futures concentrate volume in the front-month and active deferred contracts, with tight bid-ask spreads and transparent central limit order book pricing; the most liquid window is the overlap of London and New York hours. Spot gold OTC liquidity is quote-driven, fragmented across bullion banks and electronic venues such as Loco London and, increasingly, CME’s spot-linked products; spreads widen outside London-New York overlap and around major data releases. Futures publish volume and open interest daily, giving traders a sentiment gauge—open interest build during a rally signals fresh positioning, while declining open interest flags short covering—that the opaque OTC spot market cannot match. Spot’s advantage is continuity: loco London trading spans the Asian, European, and American sessions with no contract roll, making it the instrument of choice for around-the-clock macro hedges and for participants in Asia who need price exposure during their local hours.
Who Trades Which, and Why It Matters
The user base skews the choice. Jewelers, refiners, and central banks transact in spot and loco London forwards for physical procurement; miners often hedge future production with futures or over-the-counter forwards; macro funds express tactical views through the most liquid futures; ETF providers hold allocated spot metal in trust, giving retail and institutional allocators spot-like exposure with an expense ratio instead of margin calls. Retail traders gravitate to leveraged spot CFDs for small size and no expiry, or to micro futures for exchange transparency. Each structure solves a different problem: spot answers “who owns which bar, and when can I have it,” while futures answer “what is the market’s price for gold at a defined future date, cleared and guaranteed.”
Tax and Regulatory Treatment Across Jurisdictions
Tax treatment frequently decides the instrument. In the United States, futures gains and losses fall under the 60/40 rule—60% long-term, 40% short-term capital gains treatment regardless of holding period—and are marked to market at year-end under Section 1256, a substantial advantage for active traders. Physical spot gold held as a collectible is taxed at a maximum 28% rate on long-term gains, while spot ETF structures vary: grantor trusts holding allocated metal are taxed as collectibles, whereas futures-based commodity ETFs can receive 60/40 treatment. In the United Kingdom, investment-grade spot gold is VAT-exempt, futures are generally tax-free for spread betting but subject to capital gains otherwise, and CFDs carry their own regime. Regulatory perimeter matters too: futures sit under CFTC and exchange oversight in the US and MiFID II in Europe, with mandatory clearing and position reporting, while OTC spot is governed by conduct rules for bullion dealers and, in leveraged retail form, by CFD restrictions such as the European Securities and Markets Authority leverage caps introduced in 2018. A trader must confirm local treatment before selecting the wrapper, because identical gold exposure can produce materially different after-tax and margin outcomes.
