The Bank of Japan (BOJ) appears ready to edge closer to another rate hike, with growing divisions among board members fueling speculation that a move could come as soon as October. The BOJ, at its meeting on Sept. 18-19, left its official rate unchanged at 0.5%. However, the summary released on Tuesday of the discussions that took place at the meeting stated that two of the nine board members favored a hike. One argued that it may be appropriate to raise the policy interest rate again.
