The Brazilian real (BRL) was rising 0.3% against the dollar at $0.6191 as Standard Chartered Global Research raised its short and medium term ratings on the currency to overweight from underweight. "Policy makers' threshold for currency strength has increased following consolidation in Q1 (first quarter)...This suggests a lower USD-BRL range in Q2 (second quarter)," the report said.
