In a 2010 article in ''[[Harper's Magazine]]'', Frederick Kaufman argued the [[S&P GSCI|Goldman Sachs Commodity Index]] caused a [[demand shock]] in wheat and a contango market on the Chicago Mercantile Exchange, contributing to the [[2007–2008 world food price crisis]].<ref>[http://www.harpers.org/archive/2010/07/0083022 The Food Bubble: How Wall Street Starved Millions and got away with it], by Frederick Kaufman, ''Harper's'', 2010 July</ref><ref>[http://www.pacificfreepress.com/news/1/6629-the-great-food-bubble-swindle-starving-the-multitudes-for-fun-and-profit.html Democracy Now (radio show)], Amy Goodman and Juan Gonzales, Interview with Frederick Kaufman, 2010 7 17</ref><ref>{{cite web |url=http://www.pacificfreepress.com/news/1/6154-a-global-food-bubble.pdf |title=Global Food Bubble |date=6 May 2010 |publisher=Pacific Free Press |author=TRNN&nbsp;— Jayati Ghosh |access-date=30 July 2010 }}</ref>

In a June 2010 article in ''[[The Economist]]'', the argument is made that index-tracking funds (to which Goldman Sachs Commodity Index was linked) did not cause the bubble. It describes a report by the [[Organisation for Economic Co-operation and Development]] that used data from the [[Commodity Futures Trading Commission]] to make the case.<ref>[http://www.economist.com/research/articlesBySubject/displaystory.cfm?subjectid=2512631&story_id=16432870 Clearing the usual suspects], Buttonwood, ''The Economist'', 2010 6 24</ref>
