Demand for the dollar was underpinned following the release of better-than-expected U.S. data on consumer sentiment and personal sending.
The University of Michigan's consumer sentiment index came in at 78.6, up sharply from the preliminary reading of 71.8, and above expectations for a reading of 72.5.
A separate report showed that personal-consumption expenditures in the U.S. rose 0.7% in February, the largest rise since September.
The data came one day after revised data showed that the U.S. economy expanded at an annual rate of 0.4% in the three months to December, lower than forecasts for a 0.5% expansion.
The growth rate was the slowest since the first quarter of 2011, but was higher than initial estimates for growth of 0.1%.
Safe haven demand for the greenback was also supported by ongoing concerns over the situation in Cyprus and political uncertainty in Italy.
Sterling had gained ground against the dollar on Thursday after data showing that the U.K. services sector grew at the strongest pace in five months in January eased concerns over the risk of a recession.
The Office for National Statistics said U.K. service output rose 0.3% in January, the biggest rise since August, bringing the annualized rate of output to 0.8%.
The report eased concerns over prospects for a triple-dip recession after previous economic data showed that U.K. manufacturing output fell at the fastest rate in six months in January.
