Yes, there would be a review, but not a proper parliamentary process. The argument I am making is that this is such a switch from ring-fencing to full separation that it should benefit from that full process. While I obviously bow to the experience of my noble friend Lord Lawson, these things, if the circumstances dictate, can be done extremely rapidly, where the circumstance demand that kind of urgent move.
I think it is instructive to compare the process of developing the ring-fencing policy to that of this proposal for full separation. The ICB went through an extensive process of deliberation and analysis, carefully collected data, prepared a full cost and benefit analysis and compared that to full separation. It found that a robust ring-fence will insulate essential retail banking services from shocks originating elsewhere in the financial system. It will enhance the authorities’ ability to manage the failure of a ring-fenced bank, or its wider corporate group, in an orderly way. It will, therefore, deliver the financial stability benefits of separation. Ring-fencing will also preserve some of the benefits of universal banking. I made the argument of diversification and scale, not simply diversity. Customers will be able to access the full range of services from a single group: that is a marketing advantage as well. The frictional costs to the economy of ring-fencing are therefore lower than those of full separation. That is, of course, the reason we did not go for full separation. Further, in the event that the ring-fenced bank runs into trouble while the rest of the group is doing well, other group members can support it. That, of course, would not be possible under complete separation.
On a comparison of the costs and benefits, the ICB chose ring-fencing as the superior policy. The PCBS did not provide any new evidence to contradict this position. In this respect, the noble Lord’s proposal for an independent review of ring-fencing is an admission that the evidence base for full separation does not yet exist. The amendment asks us to put a policy into law and then establishes an independent review process in the hope that it might justify it. For us, this is lawmaking done backwards.
That brings me to the Government’s second and perhaps more powerful reason for rejecting this amendment. Let us imagine that a future Government decided that not ring-fencing, or full separation, but a third policy was appropriate. Imagine, for example, that it decided that a Volcker rule was the right policy, or a shift to full-reserve banking. In either case, a review that was limited to deciding whether to enact a reserve provision for separating ring-fenced banks from their groups would be no use at all, and the power would need to be repealed, along with much of the rest of the Bill. Coming back to Parliament would be the only way to give a future Government wanting to change policy the full range of options.
Therefore, on grounds of both substance and of proper legislative process, the Government continue to oppose a reserve provision for a move to full separation and I therefore urge the noble Lord to withdraw his amendment.
