Tobin Tax Could Restore Yen

While the Yen's 30% rise in 2008 is no mystery (a result of the unwinding of carry trades), its performance nonetheless defies economic fundamentals.
Exports have fallen and industrial production has collapsed, such that recession now appears inevitable.
Japan is not alone in this regard, as a number of economies have suffered unnecessarily as a result of excessive volatility in currency markets.
The solution could be the so-called "Tobin tax," which aims to limit forex speculation by levying a nominal tax on short-term currency trades.
The proceeds from such a tax would be used to restore some equilibrium in forex markets by providing Central Banks with funds for direct intervention.
While the tax itself has never been implemented, countries have previously taken to cooperating on forex matters for the sake of global macroeconomic stability.
Seeking Alpha reports:
Exchange rates have to be within a certain range for all economies to prosper.
The major economies have to work together to ensure this. If the Group of Five could work together to depreciate the "Super Dollar" in 1985, so the major nations today can and should work together to stem the surge of the super Yen.
