[Q]: Which happened first, the financial crisis or the City regaining lost ground?, Context: London's largest industry is finance, and its financial exports make it a large contributor to the UK's balance of payments. Around 325,000 people were employed in financial services in London until mid-2007. London has over 480 overseas banks, more than any other city in the world. Over 85 percent (3.2 million) of the employed population of greater London works in the services industries. Because of its prominent global role, London's economy had been affected by the Late-2000s financial crisis. However, by 2010 the City has recovered; put in place new regulatory powers, proceeded to regain lost ground and re-established London's economic dominance. The City of London is home to the Bank of England, London Stock Exchange, and Lloyd's of London insurance market.
