Argentina's peso has fallen 23% against the dollar this year, and the central bank raised rates to 40% to combat capital flight. The Brazilian real is down 15% and the Russian rouble 10% since January, while grain prices have so far shown little reaction.
Sharp currency falls in major exporters can boost their export competitiveness and pressure global prices over time, though day-to-day correlation with US grain prices has been weak.
