Despite a record-setting year for milk sales in the U.S. in 2014, a current glut in the nations milk supply may cause milk prices to drop significantly by spring of this year, according to a Jan. 17 Associated Press (AP) news report.

Already disheartened by the current glut, which is due to global factors and overproduction, dairy farmers across the U.S. say they worry that futures markets predict dwindling prices in 2015. Over in the dairy aisle, though, shoppers are beginning to milk savings by the gallon.

The AP reported that dairy farmers recognize the volatility of the industry. Less than a year ago, they struggled to meet global demand and milk prices climbed to record highs — about $25 per hundredweight, or roughly the equivalent of a 10-gallon tank, according to Mark Stephenson, director of dairy policy analysis at the University of Wisconsin.

“So, many farmers bought new equipment and expanded their herds to meet demand. But when China pulled back on its dairy imports after stockpiling milk powder and Russia imposed sanctions against the U.S. by halting trade, dairy farmers nationwide were left with a surplus,” Stephenson said.

According to the AP, every state has some dairy production, but California and Wisconsin anchor the country’s supply. The milk glut reached its peak in the Northeast over the holidays, when cooperatives asked farms to pour out some of their milk.

If prices continue to dwindle, Wisconsin dairy farmer Rick Steger says his income will decrease by a third — if not more. “I’m very worried because it’s such an extreme drop,” said Steger, whose farm is in Theresa, 50 miles northwest of Milwaukee. “Our expenses aren’t going to drop.”

Steger said he signed up for the Federal Margin Protection Program last year, but he believes it would not cushion the blows expected this year.
