The dollar was little changed against a basket of major currencies on Friday after conflicting U.S. economic data, leaving it on course for its largest weekly rise in 2017 amid a rise in expectations for inflation and U.S. interest rate hikes.
The one-week rise of just under 1 percent helped the greenback post its first monthly gain against its peers since February.
On Friday, the dollar fell to session lows after the release of a report showing U.S. consumer spending barely rose in August, but that was offset by an unexpected increase in the University of Chicago's purchasing managers' index and an in-line reading on consumer sentiment.
Federal Reserve Chair Janet Yellen said earlier this week that the central bank planned to stay on its current rate hike path, which suggested to investors that it would raise rates in December, with further increases to follow in 2018.
The Fed has raised rates twice in 2017.
