Dear Mr. Ricker,
After my testimony before the Committee on March 9, 2021, Chairman Brown requested answers to three questions submitted by Senator Daines. The questions and answers are below.
(1) Many of my colleagues across the aisle have recently spoken in favor of implementing a Financial Transaction Tax (FTT). They argue that doing so is necessary in order to reduce market volatility and make sure that Wall Street is paying its fair share. However, given that data from the Federal Reserve shows that 53% of US families owned some form of publicly traded stock in 2019 and that 80-100 million Americans have a 401k, what impact would the imposition of a FTT have on pensioners and retail investors?
The idea of an FTT is hotly debated. Supporters argue that an FTT would raise revenue for the government, reduce trading in securities, especially by high frequency traders, fall more on the wealthy than on middle- and low-income people, and therefore reduce the gap between the wealthy and less wealthy. Opponents argue that an FTT would be harmful. Extensive academic literature on FTTs exists. Scholars for the Mercatus Center have contributed to this literature.
The cost of an FTT would fall on both professional investors and individual investors. An FTT would reduce the net returns of retail investors and retirees who have mutual funds or retirement funds because retirement plans and mutual funds buy and sell securities, which are transactions that would be subject to the tax. Writers dispute the amount of the cost to individuals with retirement accounts or mutual funds.
Financial economists do not agree on all the effects of an FTT. They do tend to agree that a tax would reduce the volume of securities trading and would not produce as much revenue as expected. Some analysts claim that an FTT could cause riskier investments or more price volatility. It might be fair to say that the tax would alter securities trading behavior in unexpected and unintended ways.
Supporters of an FTT believe that it will discourage high-frequency trading (HFT). Neither Congress nor the staff of the SEC have concluded that HFT should be discouraged. As late as 2018, Congress had not determined that HFT causes undue harms that needed to be regulated and instead was keeping its policy options open while collecting further evidence. In legislation, Congress instructed the SEC staff to prepare a report assessing the benefits and risks of algorithmic trading to equity and debt markets and recommending necessary changes to federal regulation. (For practical purposes, algorithmic trading is another term for HFT.)
The SEC staff delivered the requested report in early August 2020 but did not recommend any additional regulation to curtail HFT activities. In fact, the staff did not conclude that harms from HFT outweigh the benefits and, if anything, dwelled more on the benefits. Algorithmic trading in the equities markets, the staff wrote, “has improved many measures of market quality and liquidity provision during normal market conditions, though studies have also shown that some types of algorithmic trading may exacerbate periods of unusual market stress or volatility.” In addition, the SEC staff discerned that algorithms help market participants reduce risks from the increasing complexity of many interconnected markets.
The staff also surveyed the academic literature and concluded that, “Overall, most academic studies find that algorithmic trading and HFTs have improved market quality and helped reduce transaction costs. There is ample evidence suggesting that, under normal market conditions, algorithmic trading and HFTs improve liquidity and price efficiency and reduce short term volatility.”
The staff noted that evidence of the effect of high-speed trading in periods of stress was mixed. At least “some academic studies . . . find that algorithmic trading and high-frequency trading continue to reduce volatility during periods of heightened volatility.”
(2) If the U.S. were to institute an FTT, would you expect many firms would move their trading operations to an international exchange with a more hospitable tax environment?
Capital flows freely across international boundaries and seeks the most efficient markets. Adding costs with a new securities tax in the United States inevitably will drive some amount of securities trading to lower-cost jurisdictions. According to economist Aaron Klein, “Several countries attempted large FTTs in the past and experienced significant capital migration.”
(3) Is it your belief that Congress should actively use the tax code to limit the practice of short selling? And is there any evidence to suggest that imposing an FTT would reduce the prevalence of short selling?
Short selling is socially valuable. Short sellers help to discover accurate prices and to identify companies that are overvalued or engaged in questionable conduct. Academic studies do not support the claims that short selling causes distress in the securities markets.
Tax and regulatory policy should treat short selling and short covering no better and no worse than long buying and selling. Tax, disclosure, and other obligations should be comparable and not more onerous for short transactions.
If an FTT is applied neutrally and equally to all securities sales and purchases, it would reduce short selling and covering to the same extent as long buying and selling. I am not aware of evidence that an FTT would reduce short sales more than it would reduce other securities transactions. As mentioned earlier, most commentators agree that an FTT would reduce the number of securities transactions.
The main objective of the federal tax system should be to raise revenue to fund Congress’s expenditures at the least cost to economic activity. Using tax provisions to encourage or discourage particular types of conduct or to benefit or penalize particular groups or activities leads to complexity in the law, difficulties in complying with the law, concealed differential treatment, and unforeseen and unpredictable consequences.
Very truly yours,
