I congratulate my hon. Friend on securing this debate on international banking regulations. He said that the structure is not transparent. Does he hope, as I do, that when our astute and highly regarded hon. Friend the Minister replies to the debate, she will refer to financial accounting standard No. 157, which was introduced in the US almost a year ago this week? It looked at the valuation of bank assets and put them on three levels, the third of which deals precisely with the collaterised debt obligations that brought to the surface the fact that sub-prime mortgages underpinned much of the American boom. That realisation triggered what we have seen during the year or so since. Perhaps we should be more open about the valuation systems that banks use which sometimes even they do not understand.
