There is no scheduled time for the Bank of Japan announcement and statement, expect it sometime in the 0230 GMT to 0330 GMT window

I posted a preview earlier this week: Goldman Sachs preview of the Bank of Japan meeting

Expectations for any change are basically non-existent. I am waiting for the Bank to acknowledge they have abandoned their 80tl yen JGB annual buying target. it has become irrelevant under the new YCC policy. (JGB = Japanese Government Bond and YCC = Yield Curve Control.) Is that coming today? I have no idea. If it does come, I expect there will be a knee-jerk reaction in the yen, despite it being well-flagged: USD/JPY lower at least on an announcement effect, and then a bounce back soon after.

I am also expecting at some time (not today but I have no idea when, I suspect prior to April 2018 as I said here, again, this week)

Enough from me ... Preview via Société Générale (bolding mine)

The Bank of Japan and the Central Bank of Taiwan are both expected to maintain their high degree of monetary accommodation.

  • For the BoJ this means maintaining the zero 10-year JGB yield target, and of course the negative interest rate on parts of the balances deposited with it.
  • Although output growth is strong and the labour market is tight and getting tighter, policy is driven by the fact that consumer price inflation is still way below the 2% target.

So, that's a brief preview ... and here is an even briefer one, via Barclays:

  • We expect current policy to remain intact, but will be looking for evidence of a change in the tone of the policy dialogue, possibly reflecting the more dovish bias of the Policy Board following the replacement of two members.
