Corn: 6 to 8 cents lower; weakness could be tempered by export sales.
Wheat: 8 to 10 cents lower; global economic concerns.
Soybeans: 4 to 6 cents lower; losses could be trimmed by Chinese buy.
Meal: 50 cents to $1 lower; pressure from soybeans.
Soyoil: 40 to 60 points lower; spillover from soybeans, crude oil.

Grain futures faced fresh selling in overnight trade on spillover from negative outside markets and a non-threatening near-term weather outlook. The U.S. dollar index was choppy overnight, with gold and crude oil slightly weaker. Concerns surrounding Wednesday’s vote by the Greek parliament to pass or reject the austerity package have investors on edge. A move away from risk is expected to limit buying in commodity markets this morning.
However, fresh export news signals corn and soybean futures have fallen too far too fast — spurring fresh business. USDA announced a 230,000 metric ton (MT) corn sale to an unknown destination, with 130,000 MT for 2010-11 and 100,000 MT for 2011-12. The business could be the rumored sales to China that circulated last week, but this will not be known unless the destination is officially changed, or shows up in the weekly export inspections data.
Also this morning, USDA announced a 132,000 MT soybean sale to China for the current marketing year. China has a history of canceling sales at higher levels and repurchasing at lower levels — so more fresh purchases could follow.
