Tool: Measuring Price Variability of Staple Food Commodities

Excessive Food Price Variability Early Warning System

In response to global market fluctuations of 2008 and 2010 and to support G20, Maximo Torero and Carlos Martins-Filho have developed an online tool for measuring price variability of key staple food commodities.

The three-part model provides a visual representation of historical periods of excessive global price volatility from 2000 to present, as well as a daily volatility status. It can alert policymakers when world markets are experiencing a period of excessive food price volatility.
