Listening to the Commons exchanges yesterday on the Chancellor’s proposal for a Parliamentary Committee of Inquiry into the LIBOR scandal was depressing.  It was the Commons at its worst: blame shifting; moralising; and, above all, opportunistic point scoring across the floor.  It’s not just the bankers who don’t get it; lots of MPs also do not realise the scale of the disaster that is the UK financial system.  A Parliamentary inquiry is a quite inadequate response to the scale of the problem. Some Parliamentary inquiries, notably those by the Treasury Select Committee, have done good work.  But even when not beset by party divisions they simply have not measured up to the job.  As in the notorious case of Fred Goodwin, they end up largely scapegoating individuals. Now Bob Diamond has followed his chairman in falling on his sword. It’s just as well he doesn’t have a knighthood; he could kiss it goodbye. 

Andrew Tyrie is an honourable man and will do his level best with the inquiry – if it happens.  But we can already see how inadequately he conceives the task: the inquiry will be "ring-fenced" (his words) to examine what the LIBOR tells us about the culture of the City. The LIBOR scandal is being trailed by the financial establishment as precisely that: a scandal.  In other words, a single disgraceful event, and in the manner of all scandals in Britain it is taking a predictable course: moralistic fulminations, and the sacrifice of a few prominent scapegoats.  Morals are important;  the amorality revealed in the Barclays’ e mails is shocking to normal people.  And  it is certainly the case that wrongdoers need to be pursued and punished.  But here at CRESC, where we have been tracking the financial crisis since 2007, we have been  arguing for some time that there are fundamental defects in our financial system, and that these won’t be solved by short term hunting down of scapegoats.  Faced with the  LIBOR scandal, politicians, bankers and regulators have responded  with the traditional Claude Rains defence: like Captain Renault, the character played by Rains in Casablanca, they are shocked, truly shocked, to discover that illicit gambling has been going on in the casino of the City of London.  But  the problems won’t be solved by firing a few top bankers, prosecuting a few white collar criminals, or even by conducting an inquiry into the workings of LIBOR – necessary though all these are.  We need to dispense with the illusion that a casino is the best way to organise the financial system for a modern economy – a truth that Keynes famously expressed many decades ago.

Our research reports show that the claimed economic benefits of the City for the "real" economy are an illusion, the product of effective PR over the years by the City elite.  Boring old manufacturing contributes about twice as much as glitzy financial services to the nation’s tax coffers.  And the City is doing nothing to solve our unemployment problems: throughout the great financial boom up to 2007 employment in finance was flat.  The  PR offensive has been effective because the City has enjoyed unique privileges in the government of finance, and unique access to top policy makers: both the Labour and Conservative parties have, in office, relied on paymasters from the financial elite.  And in turn they have, disgracefully, inserted financiers into key decision making positions.

The result is that the City is a web of markets proliferating increasingly complex and risky financial instruments that do little or nothing to promote welfare or efficiency in the wider economy.  The "other" scandal last week – the outrageous rip off at the expense of small business – is no single accident; it reflects the fact that finance is now in the business of creating and selling financial instruments regardless of the social harm they create.  Adair Turner’s condemnation of "useless" financial innovations is an understatement; the City has moved beyond the creation of the useless to the manufacture of the positively malign.

We need a full Leveson-style inquiry to examine how the casino is working, and to examine the web of patronage and lobbying that has allowed the City casino to trade with impunity.  An inquiry will be uncomfortable for many who were prominent in the New Labour years, and it is to the credit of Ed Miliband and Ed Balls that they have, nevertheless, recognised that full transparency is needed. We need an inquiry on the scale of Leveson, with the power to uncover the cultures and institutions that persuaded City operators that they could operate with impunity.  And we might yet get it if Labour refuses to play ball with Osborne’s proposal. But more important even than an inquiry, we need  a fundamental redefinition of the social and economic roles of finance. Banks must become public utilities with the duty to serve the wider economy, not players in casinos.  A Leveson-style inquiry would help provide the catharsis to  bring us to that point.
