Anything that represents some value, can be in the form of a good or service (offered as a product) and can be traded purely on the basis of its price is termed as commodity. The word commodity has been derived from the French word “commodite”. Around 15th century, people started using this word in English language. There are three characteristics of a commodity: use value, exchange value and a price. Commodities are very often used for trading. They are therefore commonly known as commodity derivatives. Commodity derivatives are usually different from financial derivatives. Commodity derivatives create the need for warehousing and quality plays an equally important role. But a financial derivative is completely cash based.

Everything seemed normal as he was greeted by the usual dignitaries. Everything seemed normal as he greeted all his fans and followers. Everything seemed normal until the President began his motorcade. However, what followed was far from normal. It was beyond what anybody there had thought of or ever imagined.
