Economists reduced once again their economic expansion forecasts for Brazil for this year and next in light of tepid economic activity, according to a weekly central-bank survey published Monday.

The survey's 100 respondents reduced their estimates for economic growth this year to 1.1% from 1.16% while they cut their 2015 estimate to 1.5% from 1.6%. It was the fifth-consecutive reduction of the growth outlook for this year and the sixth-straight reduction for 2015.

Meanwhile, economists maintained their estimates for inflation as measured by Brazil's consumer-price index, or IPCA, for the end of this year at 6.46%, and for next year at 6.10%.

Respondents also kept their view for the Selic interest rate at the end of this year at 11% and for next year at 12%.

The Brazilian real is expected to end this year at 2.40 to the U.S. dollar, according to the survey.

The forecast for the trade surplus this year was increased slightly to $2.01 billion from $2 billion, while the current-account deficit view was maintained at $80 billion.
