Term 3-6-3 rule Definition: An informal rule of operation of savings and loan associations in the 1950s and 1960s in which a 3 percent interest was paid on savings accounts, a 6 percent interest was charged for mortgage loans, and the president was playing golf by 3:00 o'clock in the afternoon. This informal rule is used to indicate that the savings and loan industry during this period was far removed from the high-stressed financial markets that characterize modern banking.
