IFPRI Launches Unique New Tool That Provides Early Warning of Extreme Price Variability

Washington, D.C.—The International Food Policy Research Institute (IFPRI) launched the Excessive Food Price Variability Early Warning System today. This new tool measures excessive food price variability and is the only mechanism currently available to identify time spans of increased price variability. It is updated daily and forewarns policymakers and humanitarian agencies of periods of time with excessive food price variability.

Based on sophisticated statistical modeling (NEXQ: Nonparametric Extreme Quantile Model), this first-of-its kind tool provides daily price variability ratings for four major crops—hard wheat, soft wheat, corn, and soybeans. Data for the model are obtained from closing prices of futures contracts traded on the Chicago Board of Trade and, in the case of hard wheat, the Kansas Board of Trade.

“For the first time ever, there is an instrument to measure periods of extreme price variability,” says Maximo Torero, director of IFPRI's Markets, Trade, and Institutions Division. “This tool will help to reduce inconsistent information on price variability on the global level by providing timely and transparent market information.”

The mechanism is especially timely and important as it supports two of the recommendations in the “Action Plan on Food Price Volatility and Agriculture” issued by the G20 Agriculture Ministers on June in Paris. First, it provides information to the Agriculture Market Information System (AMIS) on price variability in global markets and shows when periods of excessive price variability are occurring and how long they last. Second, it supports the design of emergency humanitarian food reserves to be coordinated by the World Food Programme. It provides policymakers and others with a global trigger mechanism to develop country-level contingency plans, including the need to release and use grain reserves during periods of extreme price variability.

“Policymakers need consistent tools to identify periods of increased price variability,” says Carlos Martins Filho, IFPRI senior research fellow. “With better and more precise information, they can devise policies to mitigate the impacts of volatility on both producers and consumers, particularly the poorest consumers in developing countries.”

By providing an early warning system to alert the world of price abnormalities for key commodities in the global agricultural markets, policymakers and other stakeholders can make better informed plans and decisions, including whether or when to release stocks from emergency grain reserves. Timely, accurate, and transparent market information is important for addressing food price volatility and achieving the ultimate goal of improving food security, especially among poor people in developing countries.



The International Food Policy Research Institute (IFPRI) seeks sustainable solutions for ending hunger and poverty. IFPRI is one of 15 centers supported by the Consultative Group on International Agricultural Research, an alliance of 64 governments, private foundations, and international and regional organizations.
