At 9.01am, the local currency declined to 4.1310/1350 against the greenback from Thursday's close of 4.1235/1250.
ActivTrades trader Dyogenes Rodrigues Diniz said strong economic recovery has been seen since a large number of people have already been vaccinated in the US and demand for all goods and services has grown rapidly.
"Investors will also focus on the US Employment Rate and US Non-Farm Payroll data due today, as those indicators will give a clearer direction of the greenback.
"Should the unemployment rate for the US come lower than forecast, it could mean a temporary rise in the US dollar," he told Bernama.
