From The Economist:
But the City can compete successfully with other financial centres only if Britain has the right policies on regulation, tax and immigration. On regulation, there is an understandable fear that an outsized financial-services industry means an outsized risk for taxpayers. The proposals from Britain’s Vickers Commission go a long way to deal with this, dividing a tightly regulated domestic banking system (the bit that puts taxpayers at risk) from a more freewheeling international market for global capital. By contrast, the thrust of many of the proposals coming out of Brussels looks harmful. Some, such as the financial-transactions tax, can be blocked by a British veto. The rest are subject to majority vote, and Mr Cameron’s stand-off with his European partners last month—supposedly to protect the City, but really to avoid having to sell a more integrated Europe to Tory Eurosceptics—has now given London’s rivals the excuse to hamstring the City.
The British government’s own policies on tax and immigration are also doing a lot of damage. The 50% tax rate, introduced by the previous Labour government in 2010, brings in little money and has made London the most taxed out of ten financial centres for high net-worth individuals. The present generation of financial bosses, who live in and like London, may tolerate it for a while, but younger ones are feeling the pull of Switzerland, Hong Kong or Dubai. As for immigration policy, the best way to win Asian business is to lure the young Asian financiers to London. Tight limits on talented immigrants damage the City’s prospects—and indeed the prospects of every bit of British business.
