You are months, at the very least, weeks, late. They run a zero interest policy and the Fed and all other central banks raised rates. There is hardly any inflation in Japan which is why they have not raised rates. Do some research because I need to agree with others, you keep on opening new threads at light speed yet make often very weak or factually incorrect points (see your dumb Maher thread).
Correct. Then yen trade has been well talked about for over 20 years at this point. It's blown multiple hedge funds attempting to bet against it. It's funny how the dumb money always thinks the trade is obvious AFTER it goes in a particular direction with increased volatility. Statistically that is never the case, however.
No fiat currency has ever survived long term. They always print more. The yen will die. Someday. But traded against what other asset? You can't actually short the yen directly. You have to also go long something else.
