Platinum has a much shorter history in the financial sector than gold or silver. Its annual production is only about 250 tonnes (equivalent to about eight million Troy ounces). Approximately 70% of the global platinum mining takes place in one place – South Africa. Its cost is determined by the cost of mining in the long run, which increases year after year. Mining costs are growing at approximately the same rate as the demand. Platinum is widely used in both the jewellery industry and the automotive industry. Roughly half the annual production of this precious metal is used to produce catalytic converters for cars. Bars and coins are produced from platinum for investment purposes. Purchase of platinum bars or platinum coins can diversify a portfolio in the long run.
