It's the question on a lot of lips ... just where (in terms of price) will the Bank of Japan intervene?

I asked for guesses, here

As you'd expect, there are some very good observations in the comments there, go and check them out

And, scanning around elsewhere:

Shusuke Yamada, Chief Japan FX strategist for BoA (I posted a bit from him yesterday)

  • At 105 there's a realistic probability of intervention
  • Probability then climbs above 50% if around 100 per dollar

Note, though ... Nomura Securities Co.'s Yunosuke Ikeda says:

  • As long as Japan belongs to G-7, any intervention will require approval from the U.S.

'Mr. Yen' (ex-MOF Eisuke Sakakibara reckons USD/JPY has to be under 100 to get intervention

I posted earlier on what its gonna take to get intervention ... watch out for comments laying the groundwork, like this:

  • FX market moves one-sided and
  • Excessive fx moves have bad impact

'Excessive' is a key word
