Since the second half of the month, in the country's fourth batch of corn storage boost, northeastern corn prices rebound gradually strengthened, part of the traders think that the State Reserve Bank of the late downstream sales are bound to increase market prices, so began to hoard a large number of supplies, resulting in the production areas of the corn market to buy the main body is unusually active. With the acquisition speed and the number of substantial rise, the cost of corn in the hands of traders also increased, and some traders have exceeded their own storage limits can afford. At the same time, the current policy of storage tasks are still not completed, and the deadline is only a month or so left, so the market purchase price of corn in the northeast is expected to continue to rise. As the current trading enterprises and grain merchants of corn purchase price has been gradually approaching the policy price, although there is the price of sales to do support, but by the downstream business demand is weak, corn prices should be limited, so the market main body into the market acquisition still have to be cautious, should not blindly chasing the high, in order to avoid the risk of a possible price fall back. Overall, in the national policy of storage and price sales policy regulation, the long-term trend of the domestic corn market is still bullish, but the North China Huanghuai producing areas may still face the pressure of the local high retracement. At the same time, by the downstream enterprise demand and poor efficiency of the double constraints, corn market price upward space is relatively limited, so the short-term price is still to oscillate upward trend.
