Corn is King -- and Therefore a Growing Problem

Corn is a key element of the U.S. food supply. It is what dairy cows eat to make milk and hens consume to lay eggs. It fattens cattle, hogs and chickens before slaughter. It makes soda sweet. As the building block of ethanol, it is now also a major component of auto fuel.

And that may signal trouble ahead.

Economists are cautioning that the nation's growing dependence on corn would make for a double jolt in the event of a drought across the Midwest: soaring prices not just for food but also for gasoline.

Analysts now warn that a "corn shock" might not be far off -- and it could lead to $5 gas and $3.50 eggs as the effects reverberate across the economy.


"We are replacing price volatility from the Middle East with Midwestern weather price volatility," said Michael Swanson, a Wells Fargo & Co. vice president and agricultural economist.

Such a disaster would occur against a backdrop of soaring prices for basic food items and other commodities that are already stressing the economy. Coffee is up 21% to date, platinum 42% and already high oil an additional 6%.

After a torrid 2007, corn prices have risen an additional 20% this year because of global demand for livestock feed, sweeteners and ethanol. The rush by American farmers to forgo other grains to plant cash-producing corn, along with weather problems, has squeezed wheat supplies, pushing the price of that grain up 21%. Soy has risen 25% this year.

Analysts are already simulating what would happen if a drought hit the corn belt. Bruce Babcock, an agricultural economist at Iowa State University, estimates that corn could reach $8 a bushel from $5.46 now.

It could happen as soon as this summer.

"The risk of a drought right now is higher than normal because of the La Niña we are seeing," Babcock said, referring to the cooling of ocean temperatures that often has a drying effect.

As any farmer can tell you, Mother Nature is fickle. The U.S. has suffered four major weather disasters since 1971 that wiped out 21% to 29% of the corn crop at a time.

Periodic bad weather, including droughts, scorching heat waves and cold, cloudy spells at just the wrong time, has reduced harvests by billions of bushels. Previously, these disasters have raised food prices. The next drought will be the first to affect gas prices.

That's because ethanol -- mostly refined from corn -- will make up about 6% of the nation's gasoline supply this year, and that's expected to rise to 10% over the next five years. The amount of ethanol used in California gasoline is expected to grow at a faster rate, reaching 10% by 2010.

But if there were a crop shortfall, the rising price of corn would prevent ethanol distillers from earning a profit, prompting them to slash production, Babcock said.
