Weather in the Northern Hemisphere continues to underpin grain prices, particularly ongoing dryness in some of Europe's key wheat-producing regions. Much of Northern Europe, the Baltics and Southern Russia have seen very little rainfall with the latter receiving just 5-20mm this week, so crops are continually being stressed. Consultancy, SovEcon, said on Friday that despite some recent rain, the extended drought period left irreversible damage to some crops which will result in lower output.
