Wild exchange rate fluctuations have bad influence on business activities. The Japanese stock price has been underestimated given her economic fundamentals. Under these circumstances, the Japanese government has worked well. They passed the supplementary budget and started to work out a financial bailout package. It was a quick and timely action.
To recover the economy immediately, the following policy measures should be included in the package and executed without delay:
Political vacuum is unthinkable in this serious economic situation. Financial resources for the policy implementation should be used temporarily and flexibly. It goes without saying that the fiscal target decided in 2006 must be maintained. The two things can live with. We are in an emergency now.
It is worth discussing whether the current value accounting system should be maintained. The Japanese government should take necessary actions together with the US and Europe when the time comes.
Foreign exchange market intervention to stop the yen getting further stronger can happen any time. Joint intervention with the US and Europe is hard to do because the dollar is also getting stronger against almost all major currencies except the yen. Japan can step into the market alone without knowing the effect.
