Tobin tax

A Tobin tax was originally defined as a tax on all spot conversions of one currency into another. It was suggested by James Tobin, an economist who won the Nobel Memorial Prize in Economic Sciences. Tobin's tax was originally intended to penalize short-term financial round-trip excursions into another currency. By the late 1990s, the term Tobin tax was being applied to all forms of short term transaction taxation, whether across currencies or not. The concept of the Tobin tax is being picked up by various tax proposals currently being discussed, amongst them the European Union Financial Transaction Tax as well as the Robin Hood tax. Tobin suggested his currency transaction tax in 1972 in his Janeway Lectures at Princeton, shortly after the Bretton Woods system of monetary management ended in 1971. Prior to 1971, one of the chief features of the Bretton Woods system was an obligation for each country to adopt a monetary policy that maintained the exchange rate of its currency within a fixed value—plus or minus one percent—in terms of gold. Then, on August 15, 1971, United States President Richard Nixon announced that the United States dollar would no longer be convertible to gold, effectively ending the system. This action created the situation whereby the U.S. dollar became the sole backing of currencies and a reserve currency for the member states of the Bretton Woods system, leading the system to collapse in the face of increasing financial strain in that same year. In that context, Tobin suggested a new system for international currency stability, and proposed that such a system include an international charge on foreign-exchange transactions. In 2001, in another context, just after "the nineties' crises in Mexico, Southeast Asia and Russia," which included the 1994 economic crisis in Mexico, the 1997 Asian Financial Crisis, and the 1998 Russian financial crisis, Tobin summarized his idea: The tax on foreign exchange transactions was devised to cushion exchange rate fluctuations.
