The price of coffee is on the rise as U.S. stockpiles dwindle, CNNMoney.com reported.

Coffee futures have skyrocketed 44 percent since June as bad weather threatens South America and talk of Brazil and Vietnam hoarding their stocks continues.

That may lead to increased costs for U.S. coffee companies, costs that will likely trickle down to consumers as retailers fall in line.

In the announcement last month of a 10 percent price increase on bagged coffee, J.M. Smucker Co., the parent company of Folgers, Dunkin’ Donuts and Millstone, cited “sustained increases in green coffee costs.”

Also in August, Kraft Foods Inc. raised the prices of Maxwell House and Yuban coffee products by about 9 percent.

“Like others in the coffee industry, we have been closely monitoring rising green coffee costs,” said Scott McCreary, president of Green Mountain Coffee Roaster Inc.’s specialty coffee unit, noting that his company has the wherewithal to absorb some increased costs in the short term.

However, “the sustained nature of the increases” that Green Mountain has experienced this summer has led the company to raise its prices by 10 percent to 15 percent. Beginning Oct. 11, that change will affect Green Mountain’s Tully’s Coffee, Timothy’s Coffee, Newman’s Own Organics and Caribou Coffee brands.

World coffee exports were down 5.2 percent in July from the year-earlier period, and a supply crunch – U.S. coffee stockpiles at multiyear lows – are exacerbating pricing concerns.

“It’s the age-old principle of supply and demand,” said Hector Galvan, a senior trading adviser at RJO Futures. “The larger coffee-growing nations like Colombia and Brazil are having really significant issues getting good crop out to the market.”
