Illustratively, according to The Banker 2004, out of the top 1000 banks globally, over 200 are located in USA, just above 100 in Japan, over 80 in Germany, over 40 in Spain and around 40 in the UK. Even China has as many as 16 banks within the top 1000, out of which, as many as 14 are in the top 500.
India, on the other hand, had 20 banks within the top 1000 out of which only 6 were within the top 500 banks. This is perhaps reflective of differences in size of economies and of the financial sectors.
