London Bullion Market Association

The London bullion market is a wholesale over-the-counter market for the trading of gold and silver. Trading is conducted amongst members of the London Bullion Market Association (LBMA), loosely overseen by the Bank of England. Most of the members are major international banks or bullion dealers and refiners.

The physical characteristics of gold and silver bars used in settlement in market is described by the Good Delivery specification which is a set of rules issued by the LBMA. It also puts forth requirements for listing on the LBMA Good Delivery List of approved refineries.

Internationally, gold is traded primarily via over-the-counter (OTC) transactions with limited amounts trading on the New York Mercantile Exchange (NYMEX) and Tokyo Commodity Exchange (TOCOM). These forward contracts are known as gold futures contracts. Spot gold is traded for settlement two business days following the trade date, with a business day defined as a day when both the New York and London markets are open for business. Unlike many commodity markets, the forward market for gold is driven by spot prices and interest rate differentials, similar to foreign exchange markets, rather than underlying supply and demand dynamics. This is because gold, like currencies, is borrowed and lent by central banks and in the interbank market. Interest rates for gold tend to be lower than US domestic interest rates. This encourages gold borrowings so that central banks can earn interest on their large gold holdings. Except in special circumstances the gold market tends to be in positive contango, i.e. the forward price of gold is higher than the spot price. Historically this has made it an attractive market for forward sales by gold producers and contributed to an active and relatively liquid derivatives market.
