Don't share view that monetary policy is reaching its limits

Even within current framework there is ample room for further easing

First issue to analyze is what factors have hampered achievement of price target

What we should bear in mind when conducting monetary policy is not its limit but comparison between its benefits and costs

Negative rates have had impact on mkt liquidity, banks' profits, so need to assess this policy

Given we have been implementing large-scale monetary easing, any additional easing entails costs

We should not hesitate to go ahead with monetary easing as long as it's necessary for Japan's economy as a whole
