Mills in southern Brazil, particularly in Santa Catarina and Rio Grande do Sul, are facing a slowdown in demand for flour, leading to challenges in purchases and sales dynamics. In Santa Catarina, mills are making gradual purchases at around R$1,350.00 CIF for deferred wheat, but sellers are holding out for higher offers. In Rio Grande do Sul, mills are buying wheat for January to secure stock, but there's a shortage of sales to mills, resulting in negotiations focused on the port. Paraná mills are delaying purchases due to the rise in dollar prices affecting wheat and flour imports. The North region sees slower transactions due to sellers' expectations of better margins, but the arrival of two ships with 60,000 tons of Argentine wheat is anticipated to help alleviate supply shortages in Rio Grande do Sul in December.
