Don't forget the carry trade isn't only about interest rates, but about the rate fo return.
A lot of the YEN being sold to buy AUD, NZD, GBP and EUR have been spent in assets demoninated in those currencies, so in case it appears that there is weakness or volatility in those asset groups afterward YEN may be repatriated.
It is worth keeping an eye on additional investement groups if trading anything predicated on varry trades.
Eternally the recent correction is very little on a long term scale, and I would anticipate a blow-off shirt when this eventually endings, which I really don't think we have had yet. GBPJPY may hit 260 before the trend changes with any significance. This is supported by my definition that market moves are faster when alterations to the most important trend happen, very similar to what we've experienced in the last few days.
As always, DYOR.
