My Lords, I thank my noble friend Lord Deighton for putting forward this amendment. As he said, it is something which the banking commission, of which I had the honour to be a member, has been calling for. It is extremely welcome and it is very good that he has acceded to it. As the noble Lord, Lord Eatwell, said, the whole idea of ring-fencing is something of an experiment. We do not know whether it is going to work and therefore it is necessary that after an appropriate time it should be thoroughly investigated to see whether it is working satisfactorily and, if it is not, to have a move to full separation.
We know for certain that full separation works; indeed, separation was the norm in this country for most of our lifetimes. It is only during the past 25 years that there has not been separation. In the old days, there were the so-called joint stock banks, which were to do with the commercial banks and did retail lending and lending to small businesses, which are now known as SMEs, and there was a completely different group called the merchant banks, which were different people and institutions. For a long time, most of them were partnerships and had a different set-up altogether. They did what is now known as investment banking and it worked extremely well. We know that separation can work but we do not know whether this idea can work, so it is right that there should be a review.
While commending the Government, and in particular my noble friend, for introducing this, I hope that it will not be necessary. That is not because the ring-fence will, as it were, be found to work. I have grave doubts about that if it persists. However, there must be considerable doubt as to whether it will persist. Some noble Lords may have seen the interesting report in
today’s Financial Times that the HSBC is thinking seriously of spinning off its UK retail and commercial banking enterprise as a separate company, with outside shareholders taking up to 30% in it. That is according to the Financial Times; we do not know, but there is a good reason for that. If the requirements of the ring-fence are really to be enforced toughly, they will make it so difficult, complicated, burdensome and onerous that many banks should, if they are rational, ask, “Is it actually worth staying together? Might it not be better for us”—the management—“and for our shareholders to separate and release increased shareholder value for that purpose?”. I hope that the institutional shareholders will also keep the banks up to the mark. That would be the happiest conclusion—that we will not even need the review because separation will happen of its own accord. However, just in case it does not we will need the review and I am grateful to my noble friend.
