international context. Table 2 compares the structure of
the banking systems in the G-7 countries. The United States
has far more banks per person (i.e., lower population per
bank) than any of the other major industrialized nations.
If the number of banks in the United States were reduced to
about 2,800, then the number of banks per person would be-
come similar to the figures for France, Italy, and the Unit-
ed Kingdom but still be much greater than for Germany, Cana-
da, and Japan. The United States also has a relatively high
number of bank offices per person (i.e., lower population
per banking office); of the G-7 nations, only Italy and Can-
ada have more bank offices per person.
The final columns of Table 2 demonstrate the very low
level of banking concentration in the United States relative
to the other G-7 countries. The three biggest U.S. banks
control roughly 13 percent of all banking assets in the
United States, by far the lowest concentration in the G-7.
The next least concentrated countries are Japan and the
United Kingdom, where the top three banks have market shares
more than double that for the top three banks in the United
States. In addition, banking system assets as a fraction of
total gross domestic product are relatively low in the Unit-
ed States compared with the other industrialized countries.
In the United States banking system assets are roughly 59
percent of GDP, which is roughly half the average of the
other six G-7 countries. When seen in a global context,
even the largest combinations being created through the so-
called megamergers in the United States are not generating
institutions that are unusually large relative to either the
banking system or the economy as a whole.
Conclusion
We are in the midst of the transformation of the U.S.
banking system from one that is effectively unfriendly to
the consumer to one that is much less so. Addressing finan-
cial services regulatory reform is very important to permit
an efficient and sound modernization of the U.S. banking and
financial system. Expanding banking powers and giving banks
flexibility to choose the most appropriate firewall separa-
tions, as long as the banks and their subsidiaries have high
levels of capital, will be an important part of any reform
effort. Market forces can be very effective in minimizing
the opportunities for conflicts of interest and avoiding any
harm to consumers. Customers can benefit from having the
option of using financial services supermarkets if they so
choose.
