Quote from Darin Newsom:
Youngtrader, that is an excellent question. We have to consider a couple of different things. 1) As you noted, July corn is in delivery though no contracts have been delivered. This can, and often does, lead to some peculiar behavior in the spreads. 2) Export SALES are strong. Last week's report showed total sales of 1.741 bb of a projected 1.75 bb. This means that there is some short-term commercial demand in this market that is helping to support the spot-month July.
The weakening carry in the new-crop spreads is fascinating as well, for as you said, carryover stocks are not going to be a problem, and neither is expected production at this point. But, the weakening carry (roughly 65 percent to 70 percent of full commercial carry) in the new-crop Dec/Mar, Mar/May, and May/July spreads would indicate the sharp selloff seen in the market over the last four weeks is starting to generate some commercial buying interest.
However, the longer-term picture is not bullish. I posted a blog item this morning looking at the corn continuous monthly chart and its bearish signals. It will be interesting to see what develops.
