SYDNEY, Aug 12 (Reuters) – U.S. wheat futures fell for the fourth straight session on Tuesday, the longest slide in a month, as exports from the Black Sea region surge.
FUNDAMENTALS
* Instead of tensions between Russia and Ukraine curbing Black Sea wheat exports, the situation is pushing Ukrainian exports to a multi-year high as toughened borrowing conditions for farmers prompt them to accelerate sales.
* Chicago Board of Trade September wheat dropped 0.46 percent to $5.44 a bushel, having closed down 0.5 percent on Monday.
* December corn eased 0.54 percent to $3.66-1/4 a bushel, after gaining 1.3 percent the session before.

* November soybeans stood unchanged at $10.73-1/4 a bushel, having closed down 1 percent on Tuesday.
* The U.S. Department of Apiculture’s weekly crop progress and conditions report showed that good-to-excellent ratings for soybeans were 70 percent as of Aug. 10, down 1 percentage point from a week earlier. Analysts had been expecting soybean conditions to remain steady.

* Forecasting the size of this year’s mammoth U.S. corn crop may pose a challenge for the USDA this year because favorable growing conditions are producing ears of corn that could have the largest average size on record, private analysts and crop experts said.
* U.S. soybean production and yield forecasts are both expected to be revised upwards by the USDA, according to the average trade estimate in a Reuters survey.
MARKET NEWS
* The U.S. dollar started trade in Asia on Tuesday in familiar territory, holding flat after a listless session overnight void of any meaningful economic data or market-moving events.
* U.S. crude oil edged up on Monday on an expectation of further draws in U.S. crude inventory, while Brent trended down despite a number of geopolitical risks.
* U.S. stocks ended higher on Monday, extending the rally from Friday as investors hoped that Russia’s move to send humanitarian aid to Ukraine would ease tensions between the two countries.
