Colombia’s financial system has experienced important transformations during the last two decades. In order to illustrate the most significant modifications, Tables 1 and 2 present a summary of the financial system’s structure during four different points in time: 1986- 1989, 1990, 1995, and 2001. Table 1 shows the assets of different types of banks (private domestic banks, foreign banks and state-owned banks), Savings and Loans corporations, and the rest of the financial system, all of them as a proportion of GDP. Table 2 complements the information by presenting the participation of each financial intermediary in the total assets of the financial system.
