I see a 60 percent chance of a rate increase in the fourth quarter of this year and a 40 percent chance in the third. Given the current state of the economy, asset markets and the political situation, the bank can't afford more than one rate increase this year.

The BOJ policy shift marks a symbolic step toward the normalization of the Japanese economy. The central bank will eventually move to raise short-term rates from zero, and that's a necessary process for Japan to achieve sustainable economic growth.

We will probably see strong fourth-quarter growth numbers, and there are no domestic factors that could derail the economy. The central bank will probably end quantitative easing in April.
