Description:The City of London’s Global Financial Centres Index (GFCI) was first published in March 2007. It rated and ranked each major financial centre in the world in terms of competitiveness. The original research was then updated and expanded and the results were presented in GFCI 2, published in September 2007. The growth and additional data in successive editions also enabled the Index to highlight the changing priorities and concerns of finance professionals.The present report, GFCI 3 (the third in the series), updates some of the external indices used in the GFCI model and adds eight new indices of features contributing to competitiveness. Since GFCI 2, 411 additional respondents have filled in the online questionnaire, thereby providing 7,193 new assessments from financial services professionals across the world. The GFCI 3 model provides ratings for centres using a total of 62 external indices (called “instrumental factors”) and a total of 18,878 assessments from 1,236 respondents (see Appendix A for more information on the GFCI Methodology.)
