SYDNEY (Reuters) - The dollar wallowed at a fresh one-month low against a basket of major currencies early on Friday, as tame U.S. inflation data added to uncertainty over when the Federal Reserve will begin raising interest rates.
A measure of core inflation rose a mere 0.1 percent in May, the smallest gain in five months, suggesting the Fed can stick to a very gradual policy tightening cycle, when it eventually does start hiking rates later in the year.
The dollar dipped as far as 122.475 yen > overnight, continuing to retreat from this week's high of 124.465. It last stood at 123.080, down 0.3 percent so far this week.
A Bank of Japan policy meeting will be the key focal point for Asia, although no fireworks are expected with policymakers increasingly wary of expanding their already radical stimulus programme.
