Unexpected spikes in food prices, price changes independent of supply and demand and other abrupt changes in the price of commodities have taken everyone by surprise. Economists have tried to uncover the causes and influences that have led to these unpredictable changes. Specialists have analyzed data starting with 2007 and found that since then food prices rose by a staggering 50 percent in less than a year putting poor countries at risk for starvation and other social anxieties.
While several economists have argued over the cause of changes the Bar Yam group was the one which accurately pinpointed the main causes of the changes. According to the group, the mathematical models highlighted two main factors: one was the replacement of food crops with biofuel ones and the other one was the speculators’ behavior which proved to be much more influential compared to the first cause.
An abrupt shift in the percentage of speculators in the market are to blame for the changes. It used to be“70 percent commercial hedgers and 30 percent speculators. The speculators are there to provide liquidity. In the summer of 2008, it was discovered that it’s now 70 percent speculation and 30 percent commercial. Now reports are coming out that it’s 85 percent speculation and 15 percent commercial. You have markets dominated by people with no real interest in the economics of supply and demand, but who are taking advantage of bets authored by Wall Street that prices will go up.” Michael Greenberger, former director of the CFTC’s Division of Trading and Markets stated.
These findings are enough to spark numerous debates as to whether government intervention is needed to regulate the percentage of speculators allowed in the market in order to avoid artificial price increases.
