Commodity market
This article focuses on the history and current debates regarding global commodity markets.  It covers physical product (food, metals, electricity) markets but not the ways that services, including those of governments, nor investment, nor debt, can be seen as a commodity.  Articles on reinsurance markets, stock markets, bond markets and currency markets cover those concerns separately and in more depth.  One focus of this article is the relationship between simple commodity money and the more complex instruments offered in the commodity markets.
