Too big to fail? Yes. But HSBC might also be too big to save
The British government's decision to separate domestic retail banks from their investment banking businesses will inevitably re-ignite speculation that HSBC is going to shift its corporate headquarters from London back to Hong Kong.
But for HSBC - and Hong Kong itself - things are a lot more difficult than a simple change of domicile and the relocation of a few senior bankers from Canary Wharf to 1 Queen's Road Central.
The British government's announcement was political rather than prudential.Certainly the professed reason for the decision - to ensure no bank is too big to fail, so preventing a repeat of the 2008 banking crisis when the government was forced to rescue two leading British banking groups - doesn't stand up well to examination.
Of the British banks that failed in the financial crisis, none collapsed because of its investment banking activities.
Northern Rock, which went bust in 2007, failed because it was overly dependent on wholesale funds to finance its retail lending.
Neither HBOS nor Bradford and Bingley, both of which collapsed the following year, had investment banking operations.
