“Respondents consider that New York, Hong Kong, and Singapore will benefit substantially from Brexit. In Europe, Frankfurt is considered likely to benefit most, followed by Paris, Luxembourg, Zurich, and Dublin.” Singapore, Shanghai, Tokyo, Beijing, Dubai, Shenzhen, and Sydney make up the remainder of the top 10 centers. The rise of Shenzhen, Dubai and Sydney eased out Toronto, Zurich and Frankfurt from the top 10. “Competition at the top of the GFCI is intense. London remains second, but the signs for the future are worrying with Asian and other European centers showing strongly,” said Michael Mainelli, executive chairman of Z/Yen.
