If this is mostly speculation and government interference in trade, will prices fall eventually?

Up to a point. Once the price spikes, speculators and hoarders will try to unload their stocks, pushing prices down, but there is a lot of pent-up demand from major importers such as Iran and Indonesia that have not purchased any international rice in 2008.
So grain will go down soon.

Anybody disagrees?
