# Weather factors in South America: Drought in Argentina and excess rainfall in Brazil weigh on markets

> Excess rain in central and northern Brazil is hampering harvest of second-crop soybeans and corn, while Argentina faces drought that is cutting soybean and corn yield potential. Only 17% of Brazil's soybeans and 25% of its corn had been harvested or sown, and Rio Grande do Sul's drought is also reducing soybean potential.
