As for the third point, I believe that the stability in foreign exchange rates led by the global standard theory holds true to a certain degree. The yen's exchange rate against the U.S. dollar since the introduction of QQE with the 2 percent inflation target has moved in the range of 100-120 yen, and appears to be roughly stable at around 110 yen.
I think that this situation can be described as stable, taking into account that the yen rose from 120 yen to 80 yen against the dollar around the time of the 2008 financial crisis. Moreover, there is another reason for the Bank's committing to the 2 percent inflation target; namely, we cannot fully grasp the actual degree of the current economic recovery.
