gold is the most popular precious metal as an investment. Investors generally buy gold as a hedge or harbor against economic, political, or social fiat currency crises. Gold price has shown a long term correlation with the price of crude oil.
the price of gold is driven by supply and demand as well as speculation. However unlike most other commodities, saving and disposal plays a larger role in affecting its price than its consumption. Most of the gold ever mined still exists in accessible form, such as bullion and mass-produced jewelry, with little value over its fine weight — and is thus potentially able to come back onto the gold market for the right price.
The most traditional way of investing in gold is by buying bullion gold bars. In some countries, like Canada, Austria, Liechtenstein and Switzerland, these can easily be bought or sold at the major banks. Alternatively, there are bullion dealers that provide the same service.
