banks by total assets during an eight- year period: from the first quarter of 1999 to the second
quarter of 2007. Bank performance indicators are analyzed. Structural similarities in the
development of the banks are examined.
A cluster analysis is applied to determine banks with a similar structure of operations. This analysis allows to estimate how the structure of the Russianbanking system has been changing over time.
