The Economic Consequences of the EU Proposal for a Financial Transaction Tax
Updated: Sep 4
Exposing the Banking Sector's Obfuscation
Writing in March 2012, Professor Avinash Persaud delivered a robust defence of the European Commission's proposal for a Financial Transaction Tax. The European Commission had proposed an EU-wide tax of 0.1 per cent on equity and bond transactions, alongside a 0.01 per cent tax on derivative trades. In response, the banking sector launched a strategy of obfuscation, making disproportionate and disingenuous arguments about the catastrophic economic damage such a tiny levy would allegedly inflict. Persaud, a former head of Currency and Commodity Research at JP Morgan, systematically dismantled these claims, proving that a sector which routinely charges far higher fees for its own services could comfortably absorb a one-tenth of one per cent tax.
The Enormous Revenue Potential
The revenue-raising capacity of the proposed tax is extraordinary. According to the European Commission study, levying this tax across the European Union would raise over £48 billion. If implemented strictly across the nine nations willing to proceed independently, including economic powerhouses like Germany, France, and Italy—it would generate £18 billion.
For the United Kingdom, applying the tax domestically would yield an additional £8.4 billion annually. Persaud contextualised this figure by illustrating how transformative this revenue could be for the British economy. With £8.4 billion, the UK government could slash corporation tax to 18 per cent, completely scrap the 50 per cent top income tax bracket, reverse £8 billion in education cuts, or more than double its international aid spending.
Dispelling the Myth of Economic Destruction
Critics of the tax heavily relied on an early, flawed output from a European Commission economic model, which initially suggested a potential Gross Domestic Product loss of 1.76 per cent. Opponents misleadingly translated this figure into a predicted loss of 500,000 jobs in the United Kingdom. However, the European Commission subsequently revised this figure down to a 0.2 per cent reduction after accounting for the fact that European companies are primarily funded by retained earnings and bank debt, rather than new equity issuance.
Persaud argued that even this revised figure is dangerously incomplete because it ignores the profound economic benefits of crisis prevention. Major financial crises historically cause an average per capita Gross Domestic Product contraction of 9 per cent. By introducing a transaction cost, the tax curbs the hyper-speculative activities of high-frequency traders and "noise traders" who inflate massive market bubbles. If the tax reduced the probability of a financial crisis by a mere 5 per cent, the resulting stability would actually boost the Gross Domestic Product level by 0.35 per cent. When combined with the Commission’s estimates, the net effect of the tax is a positive 0.25 per cent boost to the economy, equivalent to creating 75,000 new jobs in the United Kingdom alone.
The Reality of Evasion and Offshore Flight
The banking lobby frequently threatens that trading will simply migrate to untaxed jurisdictions. The report proved this fear to be unfounded by highlighting the success of existing stamp duties. Seven countries already raise £15.3 billion annually through long-standing financial transaction taxes, with the United Kingdom and South Korea accounting for almost half of this total.
The United Kingdom successfully operates a 0.5 per cent Stamp Duty Reserve Tax on equities, raising over £5 billion a year. The secret to its success is that it functions as a tax on the transfer of legal ownership. If the stamp tax is not paid, the transfer is not legally enforceable, stripping the buyer of dividends and voting rights. This makes evasion incredibly risky, which is why an estimated 40 per cent of the United Kingdom's Stamp Duty is actually paid by non-residents who cannot avoid the tax simply by trading overseas. Furthermore, global regulatory shifts requiring over-the-counter derivatives to be processed through central clearing houses mean that untaxed, legally unenforceable instruments would incur punitive capital adequacy requirements that far exceed the cost of the tax itself.
Protecting Pensioners from Speculation
Another frequent banking industry claim is that the tax will ultimately be paid by ordinary pensioners. The report decisively rebutted this by focusing on the holding periods of different market participants. The average United Kingdom pension fund is a long-term investor, holding a stock in its portfolio for an average of forty-four months. Consequently, an average pension fund would pay transaction taxes equivalent to just 0.03 per cent. This is completely marginal when compared to the annual management fees of over 0.69 per cent that banks and funds already charge these same pensioners.
In stark contrast, a high-frequency trader turning over their entire portfolio daily would face an annualised tax burden of 50 per cent. A high-frequency trader pays 1,666 times more in transaction taxes than a traditional pension fund. By penalising high-frequency speculation, the tax reduces the likelihood of the severe market crashes that routinely devastate pension values, ultimately protecting the savings of ordinary citizens.
A Tool for Rebalancing the Economy
Ultimately, Persaud concluded that a Financial Transaction Tax offers a powerful mechanism to rebalance the economy. Extremely high remuneration in the financial sector artificially attracts the brightest graduates away from productive industries. By dampening excessive financial returns during boom periods, the tax could encourage highly educated individuals to pursue careers in engineering, commerce, or scientific innovation, thereby driving sustainable, long-term economic growth.
