Given that the employment report will be released on Friday, the appetite for selling the dollar may be limited especially with the consensus for non-farm payrolls gradually creeping higher from the original reading of 200,000.
Overall sentiment hasn't changed significantly, obviously we've had a reversal and the selling has ceased temporarily... But the strength of the dollar has been relatively modest.
Any shift in policy on Thursday from the BOJ is very likely to be accompanied by a strong commitment to maintaining zero interest rates. There is no trade more obvious than selling the yen against the dollar.
