The ratio of global ending stocks to total use can be a reliable indicator of market prices (the lower the ratio, the tighter the market and the higher the price.) Currently, the stocks-to-use ratios for corn and soybeans are near record lows. The stocks-to-use ratios for wheat and rice suggest reasonably comfortable stock levels, but the shortage of milling-quality wheat has put strong upward pressure on wheat prices. Stock-to-use ratios for cotton, total oilseeds, total coarse grains, and sugar are also low. These low ratios suggest strong worldwide competition among crops for acreage in the 2011 planting season.
