Quote from m22au:
I notice that despite a classic 'risk aversion' period in recent days (Europe sovereign debt concerns, European bank debt concerns, Korean fighting), that USD/JPY has:
(1) not fallen back towards and
(2) risen to levels last seen on 5 October, above 83.90
Yeah I noticed this too. The Yen should be rallying, but it isn't. We may well have seen the end of the major Yen appreciation of the last few years. Given the high debt load, there's definitely a "tail risk" of a major depreciation at some point in the future. So IMO, long Yen is no longer a good play, and it may even be a short.
