London remains the world's best financial and commercial city, the future, however, appears to belong to Asia and Eastern Europe, whose cities represent the fastest rising regions in the latest commercial and financial research by MasterCard. Shanghai had the largest jump in overall rank - moving eight places from 2007 to 2008 - bringing it into the top 25 of this year's index and demonstrating the growing importance of Asian cities to a progressively urbanized global economy. Moscow, a gateway for the fast-growing Eastern European region, showed the greatest improvement in actual Index score and had the most significant gain on London year-over-year. Further confirming the importance of Asia and Europe in the global economy, this year's study also marks the displacement of Los Angeles from the top 10, making New York and Chicago the sole North American cities in the top grouping. The decline of Los Angeles in rank is due, in part, to factors around its role in the global financial services network, as well as the rise of European cities in the area of knowledge creation.
