Russian wheat export prices continued to decline last week following a drop in global markets, while shipments also fell amidst challenging weather conditions, analysts said. The informal restriction of the export price by the Russian Ministry of Agriculture also remains one of the influencing factors, they said. The price of 12.5% protein Russian wheat scheduled for free-on-board (FOB) delivery in the second half of February to the first half of March was $238 per metric ton, down $4 from the previous week, the IKAR agriculture consultancy reported.
