Mastercard international's recent survey on the financial situation of global cities and the list of the top ten financial cities in the world show that Asian cities occupy three seats in the list, and Mumbai is the first time to enter the list. According to mastercard international's ranking, the top ten financial centers in the world are London, new york, Chicago, Frankfurt, Tokyo, Seoul, Paris, Madrid, Milan and Mumbai. It is reported that the organization examines the financial situation of major cities in the world through five indicators: financial service network, stock trading volume, bond trading volume, derivative product trading volume and commodity contract trading volume, and each indicator has the same weight. Among them, the financial service network measures the number and layout of global banking institutions, insurance companies and securities companies in the city. Mastercard international said that these top cities are the world's major financial trading centers and capital gathering places, but the organization will also consider the specific situation of each city, such as the performance of the stock market or bond market. In addition, mastercard international has published a list of the top 50 business centers in the world, with London, new york and Tokyo among the top three. China has three cities on the list, namely Hongkong (fifth), Shanghai (32nd) and Beijing (46th).
