CHICAGO: Chicago Board of Trade wheat futures took a breather on Monday after setting 8-1/2-year highs last week on concerns about tightening supplies in exporting countries hit by harsh weather.

Russian agriculture consultancy Sovecon trimmed its forecast for Russia’s crop by 0.3% from last week in the latest estimated reduction for the world’s biggest wheat exporter.

The US Department of Agriculture on Thursday slashed its forecasts for harvests in Russia, Canada and the United States, igniting a price rally.

Russia’s declining output and higher prices have caught short international trading companies that sold wheat and other crops to Asian millers on expectations of bumper global supplies, three Singapore-based traders told Reuters.

In Europe, France’s soft wheat harvest showed uneven test weights, a key measure of milling quality, after rains, according to farm office FranceAgriMer.

“There is concern in several major regions about both wheat crop sizes and quality, with tighter than expected global wheat supplies now being generally accepted,” said Matt Ammermann, StoneX commodity risk manager.

Most-active CBOT wheat futures were down 1-3/4 cents at $7.60-1/2 a bushel at 10:15 a.m. CDT (1515 GMT). On Friday, the market hit a February 2013 high of $7.74-3/4.

European Euronext wheat futures rose on Monday, after hitting their highest level since December 2012 on Friday.

CBOT soybeans were up 3-1/4 cents at $13.68-1/4 a bushel. Corn fell 5 cents to $5.68 a bushel.

The USDA said exporters sold 132,000 tonnes of US soy to unknown destinations, the latest in a string of recent sales.

Traders are watching for results from the Pro Farmer Midwest Crop Tour this week, after dryness hurt some growing areas.

The USDA last week made a bigger-than-expected cut to its US corn harvest estimate.
