Provided that inflationary pressures ramp up in Japan

Then this will be a topic that will be more of a common theme among BOJ speakers.

Kuroda earlier came out to clarify that the BOJ is not quite ready to step into that yet, but the fact that he's even talking about it now and a bit more frequent is a shift in thinking at the central bank over the past few years.

It's something that came up even before he was reappointed, and we talked about it here saying that a silent and indecisive BOJ is not what Abe would want should Kuroda be appointed for a second term.

Kuroda is already taking steps in that regard to make clear that the BOJ isn't just going to stay the way it is over the last five years. His latest remarks earlier said that "the BOJ will not continue its current powerful monetary easing once inflation hits its 2% inflation target in a stable manner, even if the government puts pressure on the bank to keep interest rates low".

If anything, Kuroda is signalling that the BOJ is ready to take on that challenge if and when it comes. But again, the key factor is inflation. For all the time spent on talking, without inflationary pressures, this is all just a moot point.
