Gold bullion refers to gold in the form of bars or ingots, typically of high purity, that is traded based on its weight and metal content. It is often used as a form of investment or as a safe-haven asset during economic uncertainty. Gold bullion is usually produced by government mints or private refineries and is stamped with its weight and purity. Investors buy gold bullion to diversify their portfolios and hedge against inflation or currency fluctuations. The value of gold bullion is influenced by various factors, including market demand, geopolitical events, and changes in the global economy.
