Food Prices or how I learned to love ethanol.
This week, I wanted to address a question I get quite often and that is why the price of groceries seems to be constantly going up. After completing the research and sitting down to write this post, I realized that there were personal motivations, reasons I was not entirely conscious of, for researching and writing this post. Anecdotally, it breaks my heart to go to the store and see people in my city, my neighbors, struggle to pay for food. It happens with regularity, someone’s card doesn’t go through and they scramble to decide which items they really need and which can wait for another week. This is not a new phenomenon, as this happens every day in this country, but I cannot remember a time in my life when it happened as often as it has since 2008. This is however, more than mere anecdote. According to a report on NPR that aired April 25, there are 47 million Americans currently using the Supplemental Nutrition Assistance Program.
Former President Bill Clinton, at the 2012 Democratic National Convention delivered a riveting and heartfelt speech in support of President Obama’s re-election and in a way that only Clinton could, articulated the frustrations that others and I have regarding the slow pace of the economic recovery. I do not want to paraphrase, so I will simply quote his speech:
Now, look. Here’s the challenge he [President Obama] faces and the challenge all of you who support him face. I get it. I know it. I’ve been there. A lot of Americans are still angry and frustrated about this economy. If you look at the numbers, you know employment is growing, banks are beginning to lend again. And in a lot of places, housing prices are even beginning to pick up. But too many people do not feel it yet….
Now — but he has — he has laid the foundation for a new,modern successful economy of shared prosperity. And if you will renew the president’s contract, you will feel it. You will feel it.
Former President Clinton said it better than I ever could, that there are indicators the American economy is growing but most people have yet to see much of a difference. Quite frankly, people deserve better answers and explanations on this issue but the answers I found are not particularly optimistic.
The Literature: Oil, financial markets, climate change and biofuels
The literature suggests there are four factors pushing up agricultural commodity prices: biofuel production, drought in the U.S. and Eastern Europe, climate change, high crude oil prices and non-commercial (financial) trading. It would be too difficult to address all of these factors in a single post, so for this week, I will highlight the enormous changes that have occurred in the American and global biofuel industries that have permanently altered commodity markets.
According to the World Bank’s Food Price Index, international food prices are currently only 9% off their all-time highs, which peaked during the summer of 2012. Much of the gains have been concentrated in basic food items: cereals, oilseeds and dairy products which have experienced considerable volatility since 2007. After more than twenty years of declining global food prices, agricultural commodity markets surged in 2006. Global prices for maize and soybeans for example, peaked at all time highs in June 2012 with the price of maize alone jumping 25% in less than 90 days between May and July. Soybean prices increased 17% over the same period.
Biofuel production is widely understood by experts and non-experts alike, to be a central cause of rising commodity prices. Though widely agreed upon it is difficult to convey the colossal size of America’s biofuel industry and just how quickly this industrial transformation took place. Borrowing a phrase from Will Staley, one of my favorite writers, America’s ethanol industry involves, “hideously violent economies of scale” that, absent any corrective action, will continue to keep global commodity markets tight.
12 years ago in 2001, as a baseline comparison, 50 million metric tons of corn was diverted from open markets to produce biofuel. Approximately 6% of that year’s yield produced 1.7 billion barrels of ethanol. Fast-forward four years to 2005 and the amount of corn diverted to ethanol production nearly tripled to 135 million metric tons. A full 14% of all corn produced in the U.S. during that year was used to produce 4 billion barrels of ethanol. Five years later in 2010, American ethanol production multiplied another 2.5 times as 350 million metric tons of corn or 35% of total U.S. production, was diverted from other markets for ethanol. According to the World Bank, 40% of American corn was used for ethanol last year, producing 13.3 billion barrels. Putting these numbers into some perspective, the United States increased its ethanol production nearly 800% between 2001 and 2012 to the point where half our country's corn is devoted to ethanol.
As an aside, I attended a lecture in 2006 by Brad Delong, former Assistant Secretary of the U.S. Treasury and current Berkeley professor, on the successes and failures of NAFTA. Delong, while speaking about American corn subsidies, took a jab at the dystopian economic thoughts of Robert Malthus and said (I’m paraphrasing), “Malthus couldn’t have possibly imagined that a nation could produce corn at the scale the United States does today”. The United States is without question, the most prolific producer of corn the world has ever seen (in terms of scale). Now, seven years since that lecture roughly half of this historically unprecedented agro-industrial capacity is dedicated to manufacturing ethanol. That realization turned my mind inside out.
The OECD predicts that global biofuel production will double by 2021, which is the most conservative estimate I’ve read so far. There are similar projections for the other major biofuel commodities including sugarcane (34%), vegetable oil (16%) and coarse grains (14%). In January 2007, maize was priced at $150 dollars per metric ton. At its height in October 2012, maize was going for $320 dollars per metric ton, or 200% more than just five years prior.
Exacerbating the demand pressure of biofuel production is the fact that the global supply of cereal stocks have been in gradual decline since the mid 90s, averaging 3.7% decline a year between 1995 and 2007. Reserve stocks allow countries to mitigate small movements in commodity and food prices. Low stock levels however, mean that cereal markets have little room to mitigate demands for biofuel production and consumers.
Perhaps the most obvious way to illustrate how ethanol affects how much you pay at the grocery store is that 90% of American livestock feed grain, is corn. U.S. livestock producers are now using more wheat to feed their livestock because corn is becoming too expensive, which is putting pressure on global wheat prices. The documentary King Corn (2008) deconstructs your typical McDonald’s meal to illustrate the pervasiveness of corn in our food system. According to the filmmakers every part of your meal has corn in it: the beef is corn fed, the hamburger buns are sweetened with high fructose corn syrup, the fries are prepared in corn oil, your coke obviously has high fructose corn syrup as does the ketchup you dip your fries into. The amount of items in your average grocery store with corn or high fructose corn syrup would astound you (talcum powder, yogurt, milk, animal proteins, cereals, candy, crackers, oatmeal, ketchup, sodas, most types of bread). The list of course, could go on. If food is artificially sweetened and its cheap, chances are good it has corn in it.
Finally, according to researchers at the University of Illinois, the average corn farm price received has more than tripled between the 2000 and 2012. Biofuel production can help explain the medium term increase in the price of some commodities, but given the stability of its mandates and its subsidies, that does not explain the volatility of commodities markets.
Next time, I’ll tie this all together by discussing oil prices, exchange rates and global financial markets as the other major factors.
