Osborne comes to a decision on the banks — but the story doesn't end there

In his speech to Mansion House last year, George Osborne asked a question of his frosted and cumberbunded audience: “Should we restrict or split the activities of banks?” In his speech tonight, he looks set to deliver an answer of his own. As Robert Peston reports, the Chancellor is to announce that the investment and retail arms of banks will be ringfenced off from each other, so that the dice rolls of the Masters of the Universe cannot tumble across everyday savers’ cash. This does not mean a complete, Glass-Steagall-style separation between the two halves. But, rather, it follows the recommendations of the interim report of the Vickers Commision: banks will have to create subsidiaries of their investment arms, which can then go bust without excessive effect upon their retail counterparts. It would, in theory, be like a contained explosion.
