The US dollar had a relatively strong September after months of declines.
"Supported by a sharp rise in interest rates and ideas of tax reform, the US dollar is closing one of its best months of the year," said Marc Chandler, global head of currency strategy at Brown Brothers Harriman, in commentary Friday.
"The Dollar Index is snapping a six-month decline, and the euro's monthly advance since February is ending," he added.
The US dollar index climbed to its highest level in over a month earlier in the week after Federal Reserve Chair Janet Yellen's comments in Cleveland on Tuesday. Yellen suggested, "It would be imprudent to keep monetary policy on hold until inflation is back to 2 percent."
The index has since retraced some of those gains, but it remains higher for the week. It was little changed at 93.04 at 8:11 a.m. ET Friday.
The US dollar index is down 9.6% since President Donald Trump's January inauguration.
