USDA OFFICIAL SEES 7-8 BILLION DLRS CERTIFICATES There will be seven to eight billion dlrs of generic certificates on the market by the end of harvest, an Agriculture Department official said. The Commodity Credit Corp will "depend heavily" on certificates to relieve storage problems this year, Ralph Klopfenstein, Deputy Administrator for Commodity Operations, USDA, told participants at the National Grain and Feed Association's annual convention. Klopfenstein said that CCC will not be able to relocate grain in any significant amount this fall, so certificates will be used in various programs to relieve storage tightness. Klopfenstein said certificates meet the goal of allowing prices to go below loan levels and providing USDA with an inventory management tool.
