HSBC has ordered a review into whether it should move its headquarters out of Britain and potentially back to its former home in Hong Kong, threatening London’s reputation as a global hub for finance and investment. A UK law forcing banks to separate their domestic retail operations by 2019 is likely to be a key factor in any decision.
