What is the current or "spot" gold price and where does this price come from? The spot gold price is based on the price of "futures" contracts traded on "futures exchanges" operating in a number of countries.
Futures contracts, or just Futures, are standardized contracts for delivery (the seller delivers) or receipt (the buyer receives) some fixed quantity and quality of a commodity. Futures Exchanges exist in many countries to facilitate commercial trade of all major commodities. These commodities include energy products such as crude oil and natural gas, "softs" including wheat, corn, and soya beans, and metals like copper, lead and zinc. The range includes cattle, pigs, eggs, coffee and even orange juice. Gold, silver, platinum and palladium are also traded as futures.
Futures contracts are available for each month of the year. That is, a contract for delivery of December wheat can be purchased in May the year before. The purpose of futures contracts are to allow commercial producers and consumers to establish guaranteed prices and guaranteed supply of the underlying commodity. For example, a large commercial bakery that needs many thousands of bushels of wheat each month uses the futures market to ensure it has wheat at a known price for many months into the future. This practice is called hedging. There are other participants in the futures market. One large class is the speculators. Speculators buy and sell futures contracts hoping to make money on the price fluctuations - they do not intend to actually take delivery, or deliver, the commodity.
Futures contracts are traded on the floor of the exchange. You have probably seen views of this on television - people in colored vests screaming and making hand signals in what looks like total chaos. This is called an "open outcry auction" market. It is anything but chaos. The people in the colored vests work for brokers who have a "seat" on the exchange. They are buying and selling futures contracts for their clients. The details of the contracts that are bought and sold are entered into the computer system of the exchange. The exchange publishes the price and related data such as the number of contracts (volume) in real-time. The exchange sells these data feeds to companies that then make them data available to traders via brokerage houses and eventually to the public via websites like goldprice.org and newspapers.
The most recognized gold price comes from the COMEX located in New York. COMEX (Commodity Exchange) is the leading commodity exchange in the US for metals and is a division of the NYMEX (New York Mercantile Exchange). The process of determining spot gold prices on the COMEX is specified in the NYMEX "Rule Book."
The real-time, second by second, spot price of gold is the price of the futures contract of the "most active month" as it is trading on the exchange. The most active nearby month is called the "spot month." Even though there are contracts for every month of the year, some contracts are only lightly traded. In order to get an accurate spot gold and silver price the exchange uses the most active nearby month.
The "closing spot price" for the day is derived from that day's trading of the spot month futures contract. The COMEX futures trading in gold closes at 1:30 PM Eastern Standard Time. COMEX is currently operating under the following rules to calculate the daily spot close of the gold price: "Notice No. 185 of 22 June 2001 Amendments to COMEX Futures and Option Settlement Procedures" and specifically "AMENDMENTS TO COMEX RULES 4.91, 4.92 AND 4.93":
"Rule 4.91 - Futures Settlement Prices
(a) Active Month. The settlement price of the most active futures contract month shall be the average (rounded off to the nearest price tick) of the highest and lowest prices of the trades reported during the closing period, except as otherwise provided in this rule or in Rule 4.93 ("Use of Discretion to Establish Settlement Price")."
The "closing period" for gold is the last two minutes of trading. To summarize, the real-time spot price of gold is the price of the most active futures, or spot month, contract as it trades on the exchange. The spot gold close is calculated as the average of the highest and lowest prices of the trades during the last two minutes of closing period which is 1:28-1:30 PM in New York.
The spot gold price is provided in US Dollars in the spot gold chart at top of the goldprice.org website and in real time or tic by tic on the live gold price page. The spot gold price is converted from US Dollars to 29 major national currencies which are available on the gold price per ounce page. There are also conversions for the 29 different national currencies available in grams and kilos on the gold price per gram and gold price per kilo pages.
Gold contracts on COMEX are for 100 troy ounce bars. If you have a futures trading account with a broker on the exchange you can buy a gold contract and take delivery of the physical gold when the contract period ends. COMEX has a number of gold storage locations in the United States. You can go to one of these locations and get your gold bars. Also, services such as Brinks can deliver them to you.
Buying physical gold from COMEX is quite involved. Most people find it more practical to purchase physical gold in smaller amounts such as 1 ounce bullion bars and gold coins from dealers. You may be surprised to see the difference in spot gold price on the COMEX and actual gold prices today for small amounts of gold coins. For example, you can check the current gold coin (and silver coin) prices for items sold on eBay at eBay Gold Prices and eBay Silver Prices.
