Grain markets were mixed on Tuesday, with wheat achieving a new high while corn and soybeans lost ground, as the session was highlighted by an announcement that Bangladesh's top three soy crushing companies agreed to purchase $1 billion of U.S. soybeans over the next year, representing a threefold increase from last year. Weekly export inspections showed a strong U.S. corn export pace at 1.67 million metric tons (MMT), up from last week, while soybean inspections were down to 965,000 metric tons (K MT). Meanwhile, Brazil's soybean planting is estimated to be 47% complete, which is 7% behind last year's pace due to irregular rainfall.
