Summary Russia suspends participation in Black Sea grain exports dealWheat futures jump 5%, at highest since mid-Oct, corn up 2%Black Sea wheat, corn supplies at risk on Russia withdrawalU.N., Turkey, Ukraine press ahead with grain exportsSINGAPORE, Oct 31 (Reuters) - Chicago wheat futures jumped more than 5% on Monday and corn rose over 2% as Russia's withdrawal from a Black Sea export agreement raised concerns over global supplies.
Wheat futures hit a record high of $13.64 a bushel in March.
"This is an inflationary move, supporting prices of wheat and corn," said a Singapore-based trader.
Moscow suspended its participation in the Black Sea deal on Saturday in response to what it called a major Ukrainian drone attack on its fleet in Russia-annexed Crimea.
More than 9.5 million tonnes of corn, wheat, sunflower products, barley, rapeseed and soy have been exported from the Black Sea since July.
