My Lords, I support strongly what the most reverend Primate the Archbishop of Canterbury and the noble Lord, Lord Eatwell, have said. I speak in support of them because this is a particularly important issue.
In constructing a safe banking system, a number of things are taken into account, including risk-weighted assets and other matters of that kind, but there is no doubt that the leverage ratio is the single most important element in having a strong and robust banking system. This amendment is not about what number it should be. I mention en passant that the Government say that we must not interfere with what the Vickers committee recommended, yet when the Vickers committee recommended a number which they did not like they disagreed with it. Nevertheless, that is water under the bridge.
The review is quite unnecessary—although it will probably not do any harm—because the issue of the leverage ratio is peculiarly simple. Who will be responsible for setting the leverage ratio, the Treasury or the Financial Policy Committee of the Bank of England? The amendment is important because it would give the Minister the opportunity to make a clear statement. There has been movement since Committee. The Governor of the Bank of England, Mr Carney, gave evidence to the Treasury Committee in another place only yesterday saying that his understanding was that it would be the responsibility of the Financial Policy Committee of the Bank of England. We would like to have that explicitly stated by my noble friend here today.
