SyriaSyria’s civil war, Europe’s refugee crisis the result of spikes in food prices: Experts
The disintegration of Syria and Europe’s refugee crisis are only the latest tragic consequences of two spikes in food prices in 2007-08 and 2010-11 that triggered waves of global unrest, including the Arab Spring. Researchers have traced these spikes and spiraling crises to their root causes: deregulated commodity markets, financial speculation, and a misguided U.S. corn-to-ethanol fuel policy which removes nearly five billion bushels of corn from markets each year.

The disintegration of Syria and Europe’s refugee crisis are only the latest tragic consequences of two spikes in food prices in 2007-08 and 2010-11 that triggered waves of global unrest, including the Arab Spring. Researchers at the New England Complex Systems Institute (NECSI) have traced these spikes and spiraling crises to their root causes: deregulated commodity markets, financial speculation, and a misguided U.S. corn-to-ethanol fuel policy which removes nearly five billion bushels of corn from markets each year. With world food prices currently in retreat, now is the time to changes policies.
NECSI reports that in a paper published in the Proceedings of the National Academy of Sciences, NECSI researchers explain how the Arab Spring was triggered by sudden spikes in global food prices. When food becomes scarce, desperate people riot. Riots destabilized Syria and other poor countries, testing governments and sometimes leading to their fall. Many causes for the rapid rises in food prices have been suggested, but NECSI quantitatively determined that speculation caused these sharp rises in price. Additionally, the mandated conversion of corn into ethanol was linked to a steadier rise in food prices that has a serious impact on hunger worldwide.
Remarkably, the paper uses fundamental physical methods, invented for quantum field theory and developed in statistical physics and complex systems science, to determine the implications of policies intended to alleviate world hunger. This paper also provides strong validation for the role of nontraditional behavioral agents in large deviations from equilibrium market prices. This is evidence that speculation and trend following causes bubbles and crashes, a long standing controversy in economic theory.
Physical methods can be used to identify the most important behavior-affecting factors in a complex system. In this case, they point to the role of speculators and ethanol in world food prices. The fitting of actual prices to theory has a p value of 10^{-60}, and the out of sample fit is as good as many theories’ in-sample fit, p<0.001. This demonstrates the incredible accuracy that is possible for this kind of theoretical analysis of real world problems.
The ethanol mandates and the Commodities Futures Modernization Act of 2000, which allowed speculation in the commodities market, are both disastrous policy decisions that should be rolled back. However, as NECSI’s president Yaneer Bar-Yam points out, “Because of large profits for speculators and agricultural interests, a very strong social and political effort is necessary to counter the deregulation of commodities and reverse the growth of ethanol production.”
As NECSI has demonstrated, short-sighted market policies in the United States sparked food riots, which triggered the Arab Spring, which destabilized Syria. The millions of internally displaced Syrians and migrants fleeing civil war and ISIS are just the latest event in a worldwide chain reaction. If nothing is done to restore stability, this will not be the last disaster.
