A distinction is made between different groups of commodities that are listed on commodity exchanges: Energy, precious metals, industrial metals and agricultural products. Energy includes, for example, natural gas, heating oil, crude oil and diesel. Precious metals include gold, silver and platinum, industrial metals such as copper, aluminum and nickel. No physical commodities are traded on the Frankfurt Stock Exchange, but securitisations. Some of these are physically deposited with the commodities. For example, Xetra-Gold: Xetra-Gold is a certificate denoting gold holdings. One gram of gold is stored for each purchased share of Xetra-Gold, which can also be delivered to the holder on request. Wheat, soybeans, sugar or milk are sgricultural products. To make sure to get a product at a certain price, producers can buy it at the beginning of the year, even if it is not due until autumn, for example. Commodity prices can be tracked online.
