(Long Past) Time for a financial transaction tax

Katrina vanden Heuvel @ WaPo:

(A)fter years of Wall Street excess, and at a moment when new revenues are badly needed, the time has surely come for a financial transaction tax .

Indeed, support for such a tax has never been stronger — or broader. Many on the progressive left have long favored it . Now, though, another group of bleeding-heart liberals, otherwise known as the American people, is on board. When it comes to cutting the deficit, 6 in 10 Americans prefer taxing the financial industry to cutting social spending.

But this idea doesn’t just have the masses on its side; it has the elites, and even some Republican elites. Once championed by the granddaddy of liberal economics, John Maynard Keynes, the banner of a financial transactions tax has been picked up by conservative economists including Sheila Bair, George W. Bush’s appointee to the Federal Deposit Insurance Corp.


After all, the tax isn’t just a good revenue raiser. It’s smart regulatory reform.
The high-frequency traders that now dominate our markets would be hardest-hit by the tax. A top economist recently concluded that their lightning speed, algorithm-driven trading drains profits from traditional investors. And analysts fear that such mass trading strategies could lead to disaster if markets behave unexpectedly.

The new tax would discourage these kinds of trades, which would be a good thing.

Europe, at least, seems to agree. Eleven nations, led by the conservative German government, are on track to start collecting the tax by January 2014. Expected revenues: $50 billion per year.
