Lots of little global imperfections are being grouped together to justify support for wheat values, and the question is whether the hotspots are large enough in aggregate to justify the spike.  In the short term, the market has moved to a “risk off” position, with more buyers than sellers as shorts cover out.  Russian harvest results are continuing to build as fieldwork starts moving north, and will continue to dominate the wheat discussion.  Yields in Russia’s central zones are expected to be better than the south’s. Even though southern results were expected to be poor, the confirmation has hurt sentiment and is driving some cuts to production ideas.  In the US, heat in the corn belt is of concern, with temperature maps promising little relief.  Heat by itself will not kill the corn crop, but with weather maps for parts of the central corn belt still holding drier, worries exist.
