I've had a few questions in the comments on the expted time for the Bank of Japan announcement

Generally I expect it in the 0230GMT to 0330GMT time window

It can be earlier (it won't be today given the time already!), or later.

Generally speaking, the later it is the more discussion there has been and the rule of thumb is the more likely a change is coming.

That applies to 2-day meetings (like today), 1-day meetings tend to run longer cause there is only one day to thrash things out.

This is a guide to announcement times in 2015 (local Tokyo time):

  • 21 January 12.29pm
  • 18 February 11.49am
  • 17 Mar 12.04pm
  • 8 Apr 12.36pm
  • 30 Apr 1.04pm
  • 22 May 11.49am
  • 19 Jun 12.04pm
  • 15 Jul 12.18pm
  • 7 Aug 12.18pm
  • 15 Sep 12.07pm
  • 7 Oct 12.00pm
  • 30 Oct 12.22pm
  • 19 November 2015 12.17pm
  • 18 December 2015 12.51pm

Its 0305GMT now, 12.05pm in Tokyo
