There is not a great deal of focus on the Minutes of the September (14 and 15) Bank of Japan meeting.
What there is is much focus on the next meeting (October 30) and the potential for more easing (which, at this stage, Governor Kuroda appears to hint unlikely).
However, the September Minutes will be pored over for clues on the bank's thinking. Recall that the bank cut its assessment of exports and factory output at this meeting, saying both were flat. The bank cited offshore weakness. Of course there isn't a lot the BOJ can do to help demand outside of Japan (Peter Pan may disagree .... ya just gotta believe!).
On balance I don't think the Minutes will cause much of a ripple in the yen market. We'll soon see. Release is at 2350GMT.
