It has made the markets like a Texas Hold'Em table, I think. And there are no "technicals" right now, no matter what they say... it is simply a function of the fear - and like Hans Jürgen Redeker from BNP Paribas talked about earlier on Bloomberg.
I can't figure out why traders are buying yen. Maybe Bank Of Japan is selling USA treasury bonds? What happens if the USA Government attempts to borrow now?
Japanese investors are taking their money back home, as well as hedging - since interest is roughly 0% there... and they need to deliver returns. Then there are also carry trades unrolling - as well as some speculators fuelling, for sure, but the markets are illiquid.
