Under the influence of factors such as external markets, export demand, weather conditions, and profit taking operations by investors, the futures prices of the Chicago Futures Exchange collectively declined on the 14th.

On that day, the most active May contract in the corn market fell 1.25 cents to settle at 7.5425 US dollars per bushel, a decrease of 0.2%. The May wheat contract fell 12.25 cents to settle at 7.450 US dollars per bushel, a decrease of 1.6%. The May soybean contract fell 2.5 cents to settle at $13.31 per bushel, down 0.2%.

The weekly agricultural export sales report issued by the US Department of Agriculture shows that last week US net exports of corn were 1.1 million metric tons, while net exports of wheat were 554,600 metric tons while net exports of soybeans were only 79,300 metric tons.

Traders said that the harsh weather conditions in the Midwestern United States in the next two weeks have become a key factor affecting the corn market, but its positive effect is more reflected in new contracts. In addition, the U.S. dollar exchange rate index that reflected the U.S. dollar against a basket of currencies once fell to a new low since 16 months, and the rise in international oil prices also contributed to the growth of the agricultural product market. Traders said that due to the excessive increase in the price of agricultural products in the early stages, it attracted some investors to take profit-taking operations.

In wheat, as part of the Great Plains region of the United States is expected to receive a large amount of rainfall in the near future, effective relief of local drought conditions will benefit the growth of hard red winter wheat crops. At the same time, Indian wheat has enjoyed a bumper harvest, and the Black Sea region is also expected to increase its wheat exports this year, both of which add negative factors to the wheat market.

Argentina's Buenos Aires Corn Exchange expected that country’s soybean production this year to reach 49.2 million metric tons, which is higher than the previous estimate of 48.8 million metric tons.

Traders said that the soybean futures price fell to its lowest level since March 17 under pressure from selling funds, increasing global soybean supply, weak export demand, and weak US soybean spot prices.
