The prices of the CBoT wheat futures have been falling for four trading days. The rapid spread of the corona virus outside of China is depressing the prices of raw materials and stocks.
The Covid-19 virus remains the focus of the entire global economy. More and more cases are being reported in more and more countries. The exchange rate of the US dollar is increasing. Scientists are already talking about a pandemic, as the infection with the virus is spreading in countries such as South Korea, Italy and Iran.
The fact that countries outside of China are now affected is putting pressure on the stock markets in Asia and Wall Street, as investors are fleeing gold as a supposedly safe haven. Crude oil prices, on the other hand, are under pressure and the Korean won has dropped to its lowest level since August.
The current pressure on CBoT wheat is exacerbated by the fact that speculators are separating from their extremely large number of long positions in wheat futures and in some cases also relying on falling prices.
