Buying shares isn't the same as investing

For most people, the reduction announced in the budget yesterday to the limit on cash ISA’s, from £20,000 to £12,000 per annum, is an academic question. There can’t be many on an average salary who have even £12,000 available to save, let alone £20,000. The tax-free status of interest on such accounts is effectively a subsidy to those who do have that sort of money to put aside. As ever, the taxation system in the UK works to promote the flow of money from those who have less to those who have more. Who ever said that Conservative politicians – of whatever stripe – don’t believe in redistribution? They do – just in the wrong direction.

The argument for that subsidy was always that ‘saving’ was a ‘good thing’ for people to do, and should be encouraged. Reeves has effectively being saying for some time that ‘saving’ isn’t such a good idea after all – what we really need is investment. She’s right in principle, but utterly wrong in the implementation. She is arguing that those who are in a position to put aside the full £20,000 must put the remaining £8,000 into stocks and shares, but defining that as ‘investment’ is just plain wrong. Certainly, if someone buys shares in a start-up, that is an investment: the money goes into the company and is used to pay the initial costs. In return for that, the investor owns a chunk of the company in the form of shares and can expect dividends paid out of profits if the company is a success. But when they sell those shares, even if the person buying them pays two or three times as much for them, not one penny of the payment for those second-hand shares goes into the company for further investment. That doesn’t mean that the new owner doesn’t own a chunk of the company, nor that (s)he won’t receive dividends, merely that the transaction doesn’t represent a new investment in anything. It creates no added value at all.

It might, though, lead to an inflated share price. If Reeves’ approach leads to more ISA monies being used to purchase existing stocks and shares, the price (and therefore the apparent value) of those stocks and shares will increase, in line with the basic rules of supply and demand. That in turn has two effects: firstly, it increases the disparity between the ‘value’ of the shares and the underlying value of the company and its assets, and secondly it makes it more likely that those shareholders will lose some of their apparent wealth if the shares crash. And the greater the disparity, the more likely it is that there will be a crash, or at least a ‘market correction’ at some point, probably as the result of an external shock. Reeves is not only trying to force more people to risk their capital by saving in ways where the price can go down as well as up, she’s also increasing the level of that risk. All because of a dodgy definition of investment.

She’s right, though, in saying that the UK needs more investment. But if we define investment as being the creation of new assets – for instance, new companies, new equipment, new infrastructure – there are better ways of doing it than persuading people to put their money in the hands of market speculators and gamblers. Public sector investment in infrastructure is one of those, but you wouldn’t know that from listening to the Chancellor.
