The spot price of gold is the current market price at which gold can be bought or sold for immediate delivery. It is determined by trading on global commodity exchanges and is quoted per troy ounce. The spot price serves as the benchmark for all gold transactions worldwide and fluctuates throughout the trading day based on supply and demand.

The London Fix (now called the LBMA Gold Price) is a benchmark price set twice daily at 10:30 AM and 3:00 PM London time by the ICE Benchmark Administration. It is used as a reference point for pricing gold products, contracts, and derivatives globally. The fix is determined through an electronic auction process among participating bullion banks.

The retail price of gold includes a premium over the spot price. This premium covers the costs of manufacturing, distribution, dealer margins, and insurance. Premiums vary depending on the product type (coins typically carry higher premiums than bars), weight (smaller items have proportionally higher premiums), and market conditions. During periods of high demand, premiums can increase significantly.

Gold purity is measured in karats (K). Pure gold is 24K (99.99% gold). Common purities include: 24K (99.99% - investment grade bars and coins), 22K (91.67% - Krugerrands, Sovereigns), 18K (75% - fine jewellery), and 14K (58.3% - everyday jewellery). Investment-grade gold is typically 22K or higher.

Gold trades virtually 24 hours a day across global markets. The main trading sessions are: Sydney (10:00 PM - 7:00 AM GMT), Tokyo (12:00 AM - 9:00 AM GMT), London (8:00 AM - 5:00 PM GMT), and New York (1:00 PM - 10:00 PM GMT). The most active trading occurs during the London-New York overlap (1:00 PM - 5:00 PM GMT).

Gold has been a store of value for thousands of years and is widely considered a safe-haven asset. It provides portfolio diversification, acts as a hedge against inflation and currency devaluation, and tends to perform well during periods of economic uncertainty. Many financial advisors recommend allocating 5-15% of an investment portfolio to precious metals. However, gold does not produce income like stocks or bonds, so it should be considered as part of a balanced investment strategy.
