Understanding the Troy Ounce Gold Price
The gold price per ounce is the standard international quote, represented as XAU/USD under the ISO 4217 currency code system. COMEX is the world's largest gold futures market, and the troy ounce is the universal trading unit for investment-grade gold. When financial media report "the gold price," they are referring to the price per troy ounce in US dollars.
The troy ounce has been the standard unit for weighing precious metals since the Middle Ages, named after the French market town of Troyes, a major medieval trading hub. One troy ounce equals exactly 31.1035 grams, approximately 10% heavier than the avoirdupois ounce (28.3495 grams) used in everyday measurements.
This distinction matters: a "1 oz" gold coin contains 31.1 grams of gold, not 28.3 grams. The troy system persists in precious metals because centuries of established commercial practice survived the widespread adoption of the metric system.
On COMEX, the benchmark gold futures contract (ticker: GC) represents 100 troy ounces of gold with a minimum purity of 995 fineness. These contracts trade electronically on CME Globex nearly 24 hours a day, five days a week, providing continuous price discovery. The spot price, what you see quoted on our charts, represents the price for immediate settlement derived from the nearest active futures contract, adjusted for time value. Futures contracts for later delivery months trade at a slight premium to spot, reflecting financing and storage costs.
The LBMA Gold Price, set twice daily in London by a panel of accredited market makers through an electronic auction, serves as the authoritative benchmark for settling gold contracts, valuing gold-backed financial products, and pricing physical deliveries worldwide. Together, the COMEX futures market and the LBMA benchmark form the global pricing framework that central banks, miners, refiners, jewelers, and individual investors all rely on.
