Economy 9 August 2012 France also introduced a financial non-transactions tax last month It's not just a 0.2 per cent Robin Hood tax which Hollande introduced.

Not only was the country's Tobin tax implemented at double the expected rate, from 0.1 per cent of the value of financial transactions to 0.2 per cent, but a new tax specifically aimed at high-frequency trading was introduced. The Tax Policy Center's Steven Rosenthal explains how it works: The high frequency tax applies to traders that (1) use computer algorithms to determine the price, quantity, and timing of their orders (2) use a device to process these orders automatically, and (3) transmit, modify, or cancel their orders within half a second (the half a second has been set by draft administrative guidance). The high frequency tax is .01% on the amount of stock orders modified or cancelled that exceeds 80% of all orders transmitted in a month (under the draft administrative guidance). In effect, France now may tax orders that are not filled. It has created a “non-transaction” tax. The move is interesting not just because it is the first time you can be taxed for not making a financial transaction, but also because it uses the tax system to achieve a goal which many would argue should be done through regulation or criminal legislation instead. The act of deliberately placing false orders in an attempt to manipulate the market is pretty clearly something which has no place in a healthy financial system, and yet the French authorities declined to attempt to ban the act. Instead, they rendered it pointless by making it impossible to profit from. It's easier to enforce, harder to evade, and will make a bit of money for the government to boot. Seems win-win. › I have seen the benefits of aid to India French president Francois Hollande goes for a walk. Photograph: Getty Images Alex Hern is a technology reporter for the Guardian.
