A producer's decision to hold soybeans and sell corn has led to a drop in corn prices in Rio Grande do Sul and Santa Catarina, while the market in Paraná remains quiet. Industries in the region have already stocked up on local corn offerings for the next few months, leading to a surplus and lower price indications. As a result, price indications have fallen sharply, with some transactions receivable only in the second half of April. Meanwhile, soybean prices are not expected to rise, and the market is quiet in Paraná due to a lack of export competition and supply.
