Future wheat contracts in Chicago decline for a third consecutive meeting on Wednesday, approaching the lowest level of the last five years, as the dollar boost and expectations to increase global supply hold prices.

The corn has fallen slightly and soya has risen, as investors evaluated the progress of harvesting in the US, while awaiting details of US agricultural aid expected to be announced this week in response to the interruption of Chinese imports.

Since the lower Russian exports have supported the strong start of the US export period, the signs that Russia accelerates wheat missions have mitigated the climate to exports, Reuters notes.

Sovecon consultants increased its estimation of Russia’s exports of wheat in September by 0.3 million metric tonnes to 4.6 million tonnes and predicted missions of 5 million tonnes in October.

In addition, after high production in the Northern Hemisphere, the forthcoming harvests to the exporters of the southern hemisphere, Argentina and Australia now seem better than expected initially, said Dennis Voznesenski, an analyst at the Commonwealth Bank in Sydini.

Rainfalls in dry areas of the Black Sea and the US Middle Ages have also improved the prospects for the harvest of next year.
