Here's the link with the full explanation, but in brief ...
- There is no scheduled time for statement/announcement
- The more there is to discuss and debate, the longer the meeting tends to go
- Look for it some time between 0230-0330GMT, but be ready for it outside that window
For those with a clock ... yeah we are past 0230GMT now .... so it should be any time and there well be some more discussion going on than maybe we thought there would be (preview here).
The longer we wait, the more likely the BOJ is to surprise us .... though they well be discussing what they're going to do on April 30, which market consensus has as more probable for action (if any) than at this meeting.
