Russian wheat export prices rose for the second consecutive week last week due to higher prices in Chicago and Paris, analysts said on Monday. Russian wheat with 12.5% protein loading from Black Sea ports for supply in March was at $287 a tonne free on board (FOB) at the end of last week, up $4 from the previous week, agriculture consultancy IKAR said. Sovecon, another Moscow consultancy, said wheat and barley prices rose by $4 to $284 and $251 per tonne, respectively. "Russia's wheat has recovered its competitive edge after a sell-off in the previous weeks," Sovecon said. Russia doubled its wheat export tax to 50 euros ($60) per tonne starting from Monday.
