TAX ON FINANCIAL MARKET TRANSACTIONS? MERKOZY TOBIN TAX

Tobin Tax - and the Merkozy version that David Cameron rejected to protect the City of London's premier position in world markets? He may or may not have understood issues of its practicality? Probably not, since if he believed it to be unworkable he might have said so or simply gone along with it until the idea falls over? But, of course, the spat between Cameron and Sarkozy (ongoing) is a political win-win.
No one is asking publicly, however, whether taxing wholesale financial dealing transactions is technically feasible?
Whose and what massive computing facility will be needed to track & tax, or is it to be reported only by the taxable firms and are they all known in every jurisdiction when so much trading volume is cross-border?
There are enormous technical problems facing the whole concept. It is an idea that plays well with the general public and may even put the fear up some bankers who should know better. The fact is that it will take years to create a workable tax system. What are the problems?
- all cash markets do not officially report all transactions, most of them none:
- FX (foreign exchange trading) we know only its size as a rough guess from a periodic survey every few years covering only a few weeks in one month (a survey coordinated by the bank of International Settlements - BIS)
- Bonds markets turnover are only reported by what is transacted in exchanges (to be found glob ally in FIBV data), but that is a very small %, less than 5% of the total
- Money markets trading has no officially collected reported data and few people know how to even estimate what it might be - a few $trillions for sure
- We know a lot more about derivatives trading volumes because these go through exchanges, mostly, but not all; many are between banks and their clients only
- ditto commodities, which is almost all through exchanges
- there are issues about black box trading, dark pools, all the various alternative trading system engines
- every deal type has various transaction types - most complex to calculate principle amounts?
- we don't have a definite taxonomy, a set of inviolate standards to define all deals by type. Many are easily redefined, reclassifiable, which can be an interesting game if there are vraiable tax rates depending on deal type!
- should authorities tax both ends of a deal and everyone in the middle the same?
- what happens when deals are struck between jurisdictions with different tax rates?
- clearing houses only report netted data so gross data has to be estimated roughly
- internal crossing networks within large banks, institutions & universal groups is a major unknown that will tax banks and others how to measure for tax pruposes.
- It follows therefore that deals would have to be all reported gross and principal amounts, buy & sell & intermediary amounts, and maybe the tax is exerted on spreads as representing the true principal being traded in some cases. The standards are not well-defined for this.
- Would we have zero tax for internal intra-group deals? But, that would be considered a massive competitive advantage grossly unfair to medium and small financial firms.
- Also, how are multi-legged deals to be taxed? A first deal gets broken apart and re-used in further deals including all that goes via inter-dealer brokers? This is more akin to accounting and risk adjustment transactions to support an original deal. Would a tax on dealing result in higher risk-taking because all the secondary and teriary transactions for risk mitigation are taxed?
- How is market-making dealing to be tax classed when it is merely to stir the market and keep prices liquid & known?
- Shouldn't there be a tax difference between what is a customer deal and what is own-book trade or merely swapping (whether bed & breakfasting or not) between wholesale professionals.
- Will banks load all the cost of any tax onto customers?
- Then too, the publicly stated 0.01% or 1 basis point tax is ridiculous because it cannot apply to all markets since some operate on much smaller spreads & margins than the % tax imagined (according to news reports). Tobin suggested 0.5% (half a basis point) and others suggest 0.01% to 0.1%. All of these can swamp margins in one market or another.
- In FX 0.0005% can be a typical spread. Would FX (and other markets) volumes fall to such a level that liquidity and price discovery suffer to the extent that tax on taxable profits fall more than the amount raised in a transaction tax?
- Lastly, politicians and their public imagine that gross turnover in the markets is real money. Most traders have no idea either what is real in the sense of actual cash transacted as opposed to credit and derivative security or unsecured 'trade credit' in finance. The actual sums committed to the secondary markets are churned hundreds of times in a year. The apparent equivalent of the whole of world GDP is traded every week for 40 weeks a year! Of course, that is not really what is happening - it is 85% merely churning and moving prices.
Tobin years ago said his tax was unfeasible. He revived it again later. Some experts have proposed a two tuer tax to account foir the vast bulk of trading described as "noise", when really it is somewhat more than that! Others obsequious to the idea claim that modern technology makes exerting the tax, just like "stamp duty" to be eminently feasible, even easy. They must be either errant fools or paid consultants?
If a financial tax like some kind of fixed or variable stamp duty was to be made in some way realistic it should probably tax wholesale market balance sheets like a witholding tax rather than try to tax every line item of deal volume. Stamp duty tax on stock exchange equities trading is the easiest because there the spreads are largest. There is also little evidence supporting capital flight because of variations in stock exchange taxes. These are ultimately paid by customers of course!
The Merkel-Sarkozy-Tobin Tax supporting politicians and advisors imagine that several hundred $billions could be raised for good global causes. worth more than most countries' GDP or over half a per cent of world GDP. But who pays in the end?
