The Cost to Mexico of U.S. Corn Ethanol Expansion
Ethanol added $1.5-$3.2 billion to Mexico’s import bills from 2006-11

How much have U.S. ethanol policies pushed up corn prices? And how much have these higher prices cost developing countries dependent on imports for their staple foods? According to this Working Paper by Timothy A. Wise, it cost Mexico between $1.5 and $3.2 billion from 2006 to 2011, when U.S. corn ethanol production expanded dramatically and food prices rose to alarming levels.

The Working Paper, “The Cost to Mexico of U.S. Corn Ethanol Expansion,” was released May 16, 2012 in Mexico City on the eve of a key meeting of vice ministers of agriculture from the G-20 countries. They were meeting to set the G-20 agenda on food security in advance of the G-20 summit June 18-19, 2012 in Los Cabos, Mexico.

Cover of ActionAir Report "Biofueling Hunger"The Working Paper, which was released in Mexico in conjunction with a policy report from ActionAid, the international aid organization, finds that:

  • Ethanol now consumes 40% of U.S. corn production. The production of corn for U.S. ethanol has grown dramatically in the last decade, spurred by U.S. government policies and rising oil prices.
  • U.S. ethanol expansion has raised corn prices. Conservative estimates suggest that prices would have been 21% lower in 2010 without the rising demand from U.S. ethanol. Other estimates suggest that the price impact is as high as 27% for the entire 2006-11 period.
  • Mexico imports one-third of its corn, and the added cost due to U.S. ethanol was between $1.5 and $3.2 billion from 2006-11. That is between $250 and $500 million per year, ten-to-twenty times the amount the Mexican government spends on MasAgro, a productivity program for Mexico’s small-scale corn farmers.
  • This has contributed to rising hunger and food insecurity in Mexico. Corn tortillas are the staple of the Mexican diet, accounting for 40% of calories consumed in the country. Tortilla prices rose 60% over the last six years while the cost of the basic food basket jumped 53%. Meat and dairy prices, pushed up by high feed costs, increased 35%. In 2011, 56% of Mexicans suffered some period of food insecurity, and five million children went hungry.
  • The implications are even more dire for other food-import-dependent countries. Countries that grow little of their own staple foods see no benefit from higher prices for any citizens, as they have few farmers gaining from the price increases. For these countries, biofuel-related price increases are simply a growing drain on limited resources and a significant threat to the food security of their citizens.

The study recommended that the Mexican government take a strong stand in the June 2012 G-20 meetings, by demanding that biofuels, commodity speculation, import dependence, and other underlying causes of the food crisis be on the agenda. Wise found in a recent co-authored report, “Resolving the Food Crisis,” that the G-20 was undermining global efforts to address the crisis, ignoring even its own commissioned studies on food security.

As Wise concludes in the new paper, “Such policies are costing Mexico dearly. Mexico should use its position as chair of the G-20 to put biofuels back on the table.”

Media Coverage:

National Geographic video on When Food Is FuelWhen Food Is Fuel
Biofuel production is booming, up fivefold in a decade. Investment in biofuel technologies creates more renewable fuels and jobs, but producing fuels like corn-based ethanol diverts land and water resources from food crops. Biofuels can also drive up the cost of corn that is used for food, especially in developing countries that rely on imports of the grain. The Cost to Mexico of U.S. Corn Ethanol Expansionserved as a source for this National Geographic video. (September 15, 2014)
