Financial Transaction Tax

The Financial Transaction Tax (FTT) proposed for Europe comes from muddled thinking but, oddly, if the objectives were clarified this could be a good tax, not just for Europe but for the world.

Chancellor Merkel and President Sarkozy have proposed a Financial Transaction Tax (FTT) levied at a rate of 0.1% and expected to raise €57bn. The UK Chancellor of the Exchequer, George Osborne is opposed, arguing that such taxes need to be brought in globally if London is not to suffer at the expense of other financial centres. In the United States, Democrat Senator Tom Harkin and Representative Peter DeFazio are calling for a tax on stock, bond and derivative trades but the Republicans who control the House of Representatives have always opposed transaction taxes and will be hard to persuade of the benefits. I would like to see the deadlock broken by shifting the dialogue from raising tax to improving the operation of the financial system.

American economist , James Tobin put forward a proposal in 1978 to introduce a tax on all currency trades to limit the role of the speculator. He suggested that the receipts could be held centrally to help fund aspects of the work of the UN; it was this secondary objective that caught the headlines. The Tobin tax became the Robin-Hood Tax in common parlance.

In my book Adapt and Thrive: The Sustainable Revolution, I proposed a share transaction tax with the clear objective of reducing volatility and lengthening the time horizon used by investors so that the long-term planning needed for sustainable business becomes the norm. A Robin-Hood tax it was not. Investors that have to pay a small but significant percentage to switch ownership change their behaviour. Instead of grilling the management over their plans for the next quarter or the next year (a huge disincentive to adopting sustainable strategies) investors will examine the plans for the next decade and beyond. My proposal recognised the need to include in principle the major global financial centuries such as London, Frankfurt and New York but, crucial to acceptance, the revenue would remain with national governments to use as they see fit.

Financial markets provide liquidity and capital but an often quoted metric is that financial trading is one hundred times the level of trading required to support the real economy. Each successful speculative trade takes a profit from the market to appear in the bottom line of a hedge fund, investment bank or fund manager. If this is curtailed by the McManners tax then the market is more stable and supports the real economy better. Resistance arises because traders in the financial centres would see their incomes go down and there would be complaints that the tax was a drain on the market. What would we prefer; a stable market from which the government harvests some of its tax revenue or an unstable market in which the speculators rule?

Merkel and Sarkozy are misguided to argue for a FTT to raise money to bail out the euro zone; but a transaction tax to stabilise the financial system, brought in across all the main markets, with revenues retained at the national level, would be a step towards healing the financial system.
