Federal Reserve Governor Christopher Waller said on Thursday that the next few months will be critical to see whether inflation is transitory, as reported by Reuters.

Waller further noted that he expects inflation to retreat toward the Fed's goal of 2% in 2022.

"The Fed may have to act faster if inflation remains too high," he added. "I've always had a very optimistic outlook for the US economy and there are no signs of a credit-fuelled bubble."

Market reaction

These remarks don't seem to be having a noticeable impact on the dollar's performance against its rivals. As of writing, the US Dollar Index was posting small daily gains at 93.63.
