Larger corn crop could slow food inflation
St. Louis • U.S. food prices may ease later this year now that farmers have planted the second-largest corn crop in nearly seven decades.
The size of this year's corn crop will be 92.3 million acres, the U.S. Agriculture Department said Thursday. That's 9 percent larger than the average annual corn crop over the past decade. The only crop bigger in the past 67 years was planted in 2007.
Many analysts had worried that wet weather this spring would cut the number of corn acres. But record-high prices are encouraging farmers to use more acres for corn, and fewer for soybeans and wheat.
A greater crop estimate drove corn futures down 30 cents, to close at nearly $6.21 per bushel. That's the maximum price change allowed by futures exchanges. Corn rose to a record high of $7.99 per bushel earlier this month.
More expensive grain has led to food price increases this year. That could ultimately make everything from beef to cereal to soft drinks more expensive at the supermarket. For all of 2011, the USDA predicts food prices will rise 3 percent to 4 percent.
A huge harvest in August could ultimately slow food inflation. It typically takes six months for changes in commodity prices to affect retail food prices in the U.S. Analysts say consumers could see some relief at the supermarket by early 2012.
Farmers chose to plant corn at the expense of this year's soybean crop. They planted only 75.2 million acres of soybeans, about 3 percent less than last year. Farmers have a limited supply of good farmland and usually trade one crop for another on their acreage.
"It seemed to me there was $100 to $150 per acre more money in the corn than there was in the beans," said Tom Kreutzer, who planted 150 acres of corn on his farm near Wakeeney, Kan. "That's the kind of math that a lot of guys were using."
A separate USDA report Thursday estimated the U.S. had 3.67 billion bushels of corn in storage. Most analysts were expecting a reserve of 3.3 billion bushels, said John Sanow, an analyst with Telvent DTN in Omaha, Neb. If the reserve estimate is accurate, it means backup supplies could be higher this year and next. That would ease fears of a shortage.
Still, corn reserves are expected in August to hit their lowest level since 1995, according to the most recent USDA estimate. Global demand from ethanol producers and livestock owners has risen faster than farmers' production over the last decade.
Higher corn prices could make soybeans and wheat more expensive because farmers plant less of them.
A bigger crop doesn't guarantee lower food prices. A drought or flood could limit the size of the harvested crop. Many farmers planted during wet weather just because they knew they could get the crops insured.
Corn is a key ingredient in feed for poultry and livestock, and a staple in many processed foods. When corn prices rise, food processors and grocers pass along the higher costs to the consumer.
Surging corn and soybean prices are showing up at the grocery store this summer. In May, a sirloin steak cost about 7 percent more than last year, according to the most recent available Bureau of Labor Statistics figures. The price of pork chops jumped 9 percent. The price of spaghetti and macaroni noodles, which often contain soybean meal and corn syrup, jumped 13 percent.
