A good friend of mine asked "Nick, as the only banker I know, what do you think of the Robin Hood Tax? Does it make practical sense, or is it only supported by greenies like me who have no actual concept of how the system works?"
Well, I guess I have to start any response by saying I'm a very lowly employee at a very big bank. It is easy to find out which one, but I don't speak on behalf of them, or the banking industry as a whole. I'm writing as an individual. I don't want any media reports saying, "investment banker speaks out against Robin Hood tax"!
I've just been to the Robin Hood tax website, and as explained there the proposal seems to be:
- 0.05% tax on all bank transactions that do not involve an individual
- 50% of the revenue goes to domestic causes
- 50% goes to international eg poverty, climate change etc.
Apparently this will raise £250 billion a year, which assuming a US billion (rather than traditional UK billion) is £250,000,000,000.
The first thing to say is the use is irrelevant. The way the tax system works is a government raises money, and then chooses what to spend it on. So saying this will raise the money for climate change, or reducing poverty, or anything else specific is silly. You could say it will raise money to pay for benefits, or pay for the military, or pay for ministers cars. The money is just money.
So there are three separate issues here:
- Should the UK government spend £250 billion more?
- Should it raise this money in tax or reduce spending elsewhere, or some combination?
- Is the right tax to introduce this tax on financial transactions?
I don't have much to say on 1 or 2. Clearly there are many good things in the world to spend money on, and the government cannot spend on them all. Just because something is very good does not mean it should be paid for out of taxation. Some things cannot be funded, and some things are best supported by charities or the private sector rather than government. Which things these are is a matter for political debate and people differ on these - there isn't a correct answer.
However we have recently seen in the news 20 economists write an open letter saying the budget deficit should be reduced, and the right way to do it is to reduce spending rather than increase taxation.
So back to 3. I just went to look at the 2009 budget and apparently the total UK income from all sources will be £496 billion (Budget 2009 page 12). This means that this tax will allegedly raise the same amount as one half of all uk taxation this year - or more than income tax and national insurance put together. On a related note, Barclays just announced their profits for the year, and they were a record amount - 11.6 billion.
The reason I quote these sums is that money does not come from nowhere. It doesn't magically appear out of thin air. If you tax me buying a chocolate bar, the tax either comes as extra money I spend, or money the shop does not receive. This money would have to come from the banks, as it is inter-bank transactions. If Barclays made 11.6 billion in profit, then all of their profit, and all the profit of other 23 banks of equal size would all go into paying this tax. This seems an impossible result. So I think amount of money quoted as being raised is completely unbelievable.
Now I will assume that the promoters of the tax have done their calculations right for the volume of world financial transactions. If this amount of money cannot be raised, then all that can happen is volume of financial transactions is reduced. Now, you might argue this is a good thing - but everyone should be aware that this will be the primary result, reducing the volume of world financial transactions, not raising the huge amounts of money quoted.
0.05% does not sound like much, but it is a lot. We might trade an instrument called an "Interest Rate Swap" and be aiming to make five basis points on a good trade, and making this much is difficult. Five basis points is five hundredths on one percent. So while 0.05% of a deal might not sound much, this would be our entire profit on the deal. The result would be we would make almost no deals, because it would be almost impossible to make enough to pay the tax.
Would it hurt the world economy if we stopped making deals? Well, it would certainly hurt the British economy. When Barclays announced it was paying £2.7 billion in bonuses, those bonuses are taxed at 50% by income tax, and a bit more for national insurance. So over half of it is already going in tax. The rest of it presumably is either spent, in case it provides jobs, or is invested, in which case it funds companies by being invested in their shares, which provides money to build more shops or factories, which in turn provides jobs.
Secondly you have to ask what was the point of the interest rate swap. Typically we might make such a trade because of supply and demand issues for money. Pension funds might want to invest some money for thirty years, so it covers their liabilities, whereas companies might only want to borrow money for 10 years because that is how long they think it will take them to pay back for a new factory they are building. If no-one wants to borrow money for thirty years the pension fund has to accept a low rate of interest. If no-one wants to lend money for 10 years the company has to pay a high rate of interest. By a bank swapping between these products it matches supply to demand, and means the pension fund gets a better rate of return, and the company pays a lower interest rate, which is good for everyone.
Also notice that if the tax came into effect, if this transaction was done, the bank would have to pass the tax on to the pension fund or the company.
So what is my conclusion?
Firstly, I don't think I am wise enough to comment on this question as to what the government should spend our money on, or whether they should raise money through taxes or reduce spending.
Secondly, numbers being talked about for the amount of revenue raised are ridiculous, and just will not happen.
Thirdly the primary effect of this tax will not be to raise the amounts of money talked about, it will be a huge reduction in the volume of financial transactions. This may or may not be a good result, but no-one proposing the tax is talking about this.
So I think the intended consequences of the tax will not happen, and the unintended consequences could be huge and harmful, and clearly have not been thought about properly by the people proposing it.
