 日経の記者が最近の市場の乱高下は、1)米国の金融政策の不安定性によるものか。2)日本の金融政策への信頼性に欠けるという見方があるが、議長はどう思うか? というもの。

 これに対してバーナンキは、市場のボラテリティは日銀の政策に論理的にみて関係している。しかしそれは信頼性に欠けるというのではない。実に長い間、デフレが続いてしまっているために、日銀のインフレ目標2%実現をするという努力が、まだ市場参加者に十分に理解されてないためにおこるかく乱である、いまの日銀の努力の方向性と「三本の矢」を支持しているし、そのかく乱もやがてこの努力が結実する中で解消されるだろう、というのがバーナンキの意見である。

AKIO FUJII. I'm Akio Fujii, Nikkei Newspaper. Thank you, Chairman. Recently, we
have seen great volatility in Japanese market--equity, JGB, and foreign exchange. Some say these volatility is due to uncertainty to the Federal Reserve’s policy direction, but others say this is due to lack of confidence to the Bank of Japan's monetary policy. So how do you view the Bank of Japan's efforts? Do you still support Bank of Japan policy? And the other question is: How much do you pay attention to the spillover effect to the international market when you consider exit strategy?June

CHAIRMAN BERNANKE. Well, I think the volatility is mostly linked to the Bank of
Japan's efforts, and that would seem logical, since in earlier episodes when the Fed was doing asset purchases and the BOJ was not doing anything, there was no volatility. So it sort of, it seems logical that the change here is the change in BOJ policy.
The BOJ is fighting against the very difficult entrenched deflation. Of course, deflation
has been a problem in Japan for many, many years, which means that expectations are very much--the public's expectations are for continuing deflation, and therefore it takes very aggressive policies to break those expectations, since they get inflation up to the two percent target that the Bank of Japan has set.
So that's why it's difficult, they've had to be very aggressive. That aggressiveness in the
early stages of this process, where investors are still learning about the BOJ's reaction function, it's not all that surprising that there's volatility. Also, the JGB markets are less liquid than say, the treasury market for example. So I, you know, I think that's something they need to pay close attention to, but on the whole, I think that it is important for Japan to attack deflation. And I also agree with the three arrows, the idea that besides breaking deflation, it’s important to address physical and structural issues as well. So, I'm supportive of my colleague, Mr. Kuroda, and I'm supportive of what Japan is doing, even though it does have some effects on our economy as well.
The--there are a lot of reasons why emerging markets and other countries experience
capital inflows and volatility. Some of them have to do with changes in growth expectations. For example, we've seen a lot of changes in growth patterns in the emerging markets recently. Some of it has to do with risk-on, risk-off behavior, and some of it probably does have to do with monetary policy in advanced economies, which includes of course the United States. We do take it--pay attention to that. I frequently meet with colleagues from emerging markets at the G20 for example, and we discuss these issues. I think the right way to think about it is that, as the G7 and the G20 both have noted, that what U.S. monetary policy, like that of Japan, is trying to do is trying to help this economy grow. And a global recovery, a global--strong global growth depends
very much on the U.S. growing at reasonable rate. And so, while there is some effect, I think the net effect, including a stronger U.S. economy, is on the whole positive, and I think most of my colleagues in emerging markets recognize that. That being said, anything we can do through communication or other means to try to minimize any overflow effects or side effects, we will certainly do.
