Financial transactions tax : Recipe for disaster ?

    Wall Street is widely blamed for causing the current economic mess in the US, so why not let it pay for it ? The idea is to impose a 0.25% tax on the value of stock transactions, and on a variety of derivative transactions. Indeed, a Bill introduced last week in the US House of Representatives is called the “Let Wall Street Pay for the Restoration of Main Street Act”. Proponents of this Bill believe the legislation could raise $ 150 billion per year.

    A small increase in trading costs would, according to supporters, be a manageable burden, and it will be borne by the speculators who the Bill’s authors apparently believe (to judge by the Bill’s name) created the financial mess. Across the Atlantic, Prime Minister Gordon Brown of Britain has supported the idea as a way to take the burden off taxpayers during a time of financial crisis. In reality, the tax would deal a poorly-timed blow to long-term investors everywhere.

    Proponents of a transactions tax misunderstand the way markets work. The bubble in home prices in the US was not caused by the rapid buying and selling of individual family homes. The financial crisis was primarily a liquidity crisis and a credit crunch, and the major problem with collateralised mortgage- backed bonds was that they declined significantly in value and became illiquid. A transactions tax that would have reduced trading and made repurchase agreements more costly could have made the problem even worse. Moreover, the Wall Street would not actually foot the bill for the presumed $ 150 billion tax as the authors of the Bill believe. In fact, the tax would simply be added to the cost of doing business, burdening all investors; not just the speculators. Some argue that high-frequency traders, who reportedly execute 70% of the equity market trades, would pick up the lion’s share of the Bill. But high-frequency traders are not villains — they play an important role in improving market efficiency.

    Often mischaracterised as speculators, high-frequency traders scour markets for minor mispricings and arbitrage trading opportunities. They buy and sell stocks in an instant, hoping to earn pennies on a trade. Far from destabilising or creating volatility in the market, their actions significantly increase trading volume, reduce spreads, promote price-discovery, and ultimately reduce transaction costs for long-term investors. Such trades might not be doing God’s work, but they are socially useful.

    Transaction costs have declined significantly over the past ten years, thanks to the many structural changes in equity markets, including trading in decimals instead of eighths, the proliferation of scores of trading venues that function as exchanges, and an explosion of high-frequency trading. US-based investment management company Vanguard has estimated that total transaction costs on an average trade have fallen by at least 50%, resulting in approximately $ 1 billion of annual savings to its investors. When magnified across the whole investment industry, investors have probably saved tens of billions of dollars in transaction costs.

    Transactions taxes would make most current high-frequency trades unprofitable since they depend on the thinnest of profit margins. Trading volume would collapse, and there would be a dramatic shortfall in the tax dollars actually collected by the government. Market liquidity would decline, bid-offer spreads would widen, and all investors would pay significantly higher costs on their trades.

    A tax on financial transactions would have to be imposed internationally to prevent a particular national market from being disadvantaged. It would be very difficult to achieve universal international consensus regarding the details of such a tax. In our environment of global capital markets, it would be virtually impossible to enforce it reliably.
