Aug. 13 (Bloomberg) -- Sudakshina Unnikrishnan, a commodities analyst at Barclays Capital, talks with Bloomberg's Rishaad Salamat about the outlook for wheat and corn prices.¶ Wheat futures surged to the highest price in almost two years on Aug. 6, a day after Russia declared a ban on grain exports amid the worst drought in at least 50 years and the country’s Prime Minister Vladimir Putin proposed that Kazakhstan and Belarus follow suit.
