The currency is hovering around its highest levels since April last year.
"The combination of higher relative interest rates, stronger US growth and increasing demand for defensive US exposure continues to provide a powerful set of tailwinds for the greenback," said Chris Weston, head of research at Pepperstone Group Ltd in Melbourne.
