Italy has imposed a levy of 0.02 percent on all stock market transactions lasting less than half a second, the Finance Ministry in Rome announced Monday. The move is part of a series of new financial transaction taxes implemented in the wake of the 2008 financial crisis, it added.
Italy's new measure came as regulators in the European Union and the United States are discussing cracking down on a sector which has dramatically increased in recent years. In Europe, high-frequency trading accounted for 6.7 trillion euros ($8.8 trillion) in equities trading volumes last year, more than one third of the total.
High-frequency trading firms use computer algorithms to dart in and out of equities markets faster than the blink of an eye, trying to profit from price changes.
They've been blamed for causing the so-called ‘flash-crash' in the United States in May 2010 when the stock market dropped more than 1,000 points, or nearly 10 percent, within a matter of minutes.
In Italy, investors said they were concerned the tax could drastically reduce trading volumes, stressing that the rapid financial transactions provide liquidity to markets.
However, the trading method is under scrutiny in many countries. In the European Union, a draft proposal put forward by the executive Commission is currently being negotiated between the EU Parliament and the EU governments.
