Investing.com– Most Asian currencies firmed on Friday as a rebound in the dollar cooled before an upcoming address by Federal Reserve Chair Jerome Powell, where he is expected to provide more cues on interest rate cuts.

Broader Asian currencies advanced, but were set for a muted weekly performance as optimism over lower U.S. interest rates was offset by renewed concerns over slowing economic growth.

Japanese yen surges as Ueda says rates too low

The BOJ’s Ueda said that short-term interest rates were still too low, and needed to be brought up further to hit neutral levels. He also reiterated the bank’s recent messaging that it will raise interest rates further if inflation remains steady. 

Ueda’s comments boosted the yen, which has been on a tear since the central bank hiked rates by 15 basis points in late-July. The prospect of higher rates presents more upside for the yen. 

But this notion was somewhat offset by mixed consumer price index inflation data for July. While and CPI both rose, a key underlying inflation print, which is closely watched by the BOJ, fell below 2%, sparking doubts over just how much headroom the BOJ has to hike.
