 Frederick Kaufman, a contributing editor of "Harper's Magazine", argued in a 2010 article that Goldman's creation of the Goldman Sachs Commodity Index (now the S&P GSCI) helped passive investors such as pension funds, mutual funds and others engage in food price speculation by betting on financial products based on the commodity index.These financial products disturbed the normal relationship between supply and demand, making prices more volatile and defeating the price stabilization mechanism of the futures exchange.A June 2010 article in "The Economist" defended commodity investors and oil index-tracking funds, citing a report by the Organisation for Economic Co-operation and Development that found that commodities without futures markets and ignored by index-tracking funds also saw price rises during the period.
