Here is a 100-word summary of the article:
The US tariffs on Mexican and Canadian goods, which were implemented on Tuesday, led to a sharp decline in corn prices, with most-active CBOT corn futures plummeting 8.6% in the week ended March 4. Corn speculators sold off their net long positions, with a record reduction in gross longs. The move was seen as a risk-off strategy rather than a bearish vote. Meanwhile, soybean and wheat prices also fell due to new short positions. However, with the delay of US tariffs on Mexico and Canada, corn prices rallied 4% over the last three sessions. The US Department of Agriculture’s supply and demand report is expected to be released on Tuesday.
