Concentration of world banking and the role of U.S. banks among the 100 largest, 1956–1980

During the past two decades, international banking activity has grown rapidly. With institutional change of such magnitude taking place, it is interesting and potentially useful to look at the nature of the change. This paper examines two dimensions of this change: the trend in concentration of banking assets in the world's largest banks, and the relative position of banks from various countries among the world's largest banks. The data indicate that the percentage of banking deposits accounted for by the world's largest banks generally has increased steadily since 1956. The data also reveal that the importance of U.S. banks within the world's largest banks has declined dramatically since 1956. It is suggested that this trend is the result of the readjustment to the distortions of WWII, the rise of the commercial paper market in the U.S., and the large number of U.S. banks compared to other countries.
