I will be brief, Mr Howarth. I just wanted to respond to some of the points made by my colleague the hon. Member for Wyre Forest (Mark Garnier). Nobody from my side of the House disputes that the bank levy was in need of reform. Indeed, he made it sound far too well organised and manufactured; it was ad hoc, arbitrary and unpredictable, and it definitely needed to be replaced by something more predictable. Therefore, we are in no way rejecting the notion of moving to a surcharge on profits, which could be an effective way of raising the funds from the banks and, in a sense, of surcharging them for the social service that we provide through the Treasury in protecting them.
I do not go as far as the hon. Gentleman in relation to what I would describe as the gentle blackmail from HSBC and Standard Chartered Bank. If anyone looks at the turmoil in the Asian markets and in China at the moment, they will not think that it was a good moment for a bank to shift their headquarters from London to Hong Kong.
Let us accept that there will be a change. Our view is that we need a mechanism that allows the Treasury to use statutory instruments to vary the rate and the application of the surcharge as it evolves and as we learn whether it is impacting adversely on some banks, building societies and mutuals. That is all we are saying. We are trying to find common ground with the Chancellor. We are moving in the same direction, but the Government are rushing the application. They are making it too uniform and are choosing arbitrarily a rate of surcharge that is simply designed to reproduce the current level of tax yield. That is a bad way of approaching how we manage the surcharge on the banks.
I suppose the essence of the argument—this is really where I want to go—is that there are differences between the challenger banks and the larger banks. Those differences are not just based on their level of profit. It is quite clear that it is proportionately more expensive for the smaller
banks to provide the capital to support the credit risk in their loans once it is weighted against their risky assets. We know that from the work that has been done by the Competition and Markets Authority, and I would prefer to take its view rather than the special pleading from the banks—even the special pleading from the challenger banks.
The Competition and Markets Authority has looked at the expense to the different scale of banks in providing the capital to support their credit risk. It has come up with figures that say that on a typical £100,000 loan to a small business, a challenger bank, or a bank of that scale, has to put aside roughly £8,000 per £100,000 loan, compared with about £6,000 from one of the very large banks. The mathematical reason for that is quite simple; it is not rocket science. The smaller bank with the smaller balance sheet is carrying proportionately more systemic risk on each loan. When a small bank loses a customer or has a non-performing loan, it is quite costly to it given the scale of its balance sheet. Therefore, when we start doing the risk-weighted analysis, it will have to put more capital by; it will cost it more. It is economies of scale. Big banks have economies of scale. A specific non-performing loan to a small business is a relatively small risk to the larger bank, so the cost to it will be small. It follows on from the matters of big and small economies of scale. Nevertheless, they act as a barrier to the smaller banks being able to grow.
If we impose a uniform profits surcharge on all the banks, there is a higher real burden on the smaller banks. I would like the Treasury to take that into account as we move along, and have the powers to be able swiftly to shift the rates. I was trying not to be prescriptive in laying down how we would set different levels for different kinds of banks; I wanted a system to evolve. I want the Treasury to have the powers to do that so that if it does prove to be more costly for the challenger banks and to be taking more from their profits and their ability to raise capital, we might think about different kinds of banding, and that would be up to the Treasury to consider. We are simply saying that the smaller banks have different cost structures and therefore different risk elements, which means that imposing a single levy on profits across all the banks, big and small, is a bit too arbitrary and a bit too ad hoc. In other words, it brings us back to the sort of problems that we had with the original bank levy.
