Globally, the U.S. dollar held largely steady in early Asian trading on Friday as investors looked to fresh catalysts after the Federal Reserve's meeting, with the greenback inching higher against the yen ahead of a policy decision from the Bank of Japan, Reuters reported.
The dollar index tacked on 0.1%, recovering slightly from a three-and-a-half-year low on Wednesday after the Fed cut rates by 25 basis points but signaled it was in no hurry to reduce borrowing costs quickly in coming months. The U.S. currency remains on course for its third straight weekly loss.
Against the yen, the dollar was last up 0.1% at 148.085 yen after data earlier showed core consumer prices in Japan rose at their slowest pace in nine months.
The euro was 0.1% weaker at $1.1777, paring gains for the week after hundreds of thousands took part in anti-austerity protests across France on Thursday.
Sterling was at $1.3555, down 0.1% so far on the day, after the Bank of England kept interest rates on hold and slowed the pace of its programme to run down its government bond stockpile on Thursday.
