A Tobin tax – to be or not to be? (updated)

Adair Turner, chairman of the Financial Services Authority, the UK’s financial sector regulator, has proposed the possible use of Tobin taxes to curb destabilising financial transactions. The late James Tobin, winner of the 1981 Nobel prize in Economics, argued that a very small tax (between 0.1 and 1 per cent) should be imposed on foreign exchange transactions to dampen destabilising foreign currency speculation and thereby reduce exchange rate fluctuations. Lord Turner’s proposal would apply to a whole range of financial transactions, putting some friction in these very volatile and often highly leveraged markets. Such a tax would discourage some of the riskier and more exotic transactions on which many of the bonuses of bankers have been based.

Not surprisingly, his proposals have been met with derision by many in the banking sector. Many politicians too have been critical, arguing that the taxes will divert financial business away from London to other financial centres around the world. And yet, at the G20 summit in Pittsburgh on 24/25 September, both the German chancellor, Angela Merkel, and the French president, Nicolas Sarkozy, argued in favour of such taxes. The result was that the IMF was asked to investigate the practicality of using Tobin taxes on financial transactions as a way of reining in more risky behaviour. A week later the IMF, while ruling out a simple Tobin tax, came out in favour of taxes on the global financial sector designed to reduce speculation.
