rice shortage?

It was in the news last night that costco and sams warehouse club are limiting the number of bags of rice customers can purchase. They did not say that we have a shortage, all they are saying it is because of the "recent supply and demand trends" and some customers are stocking up in anticipation of the increase in prices. The limitations are more on the imported rice like jasmine, basmati and long grain rice. There were even notices on their shelves to let the customers know that they cannot purchase so many bags of rice. Hope this is just temporary and we want to see more of our favorite jasmine rice on the shelves.
