The Infinite Banking Concept® began with the book Becoming Your Own Banker by R. Nelson Nash.
The following excerpt from the book can best answer the question: “What is Infinite Banking?”
“This book is not about investments of any kind. It is about how one finances the things of life. It is not about rates of return. As time goes by, interest rates are up and interest rates are down — but the process of banking goes on no matter what is happening. It is a well-known fact that banks make more money during times of low interest rates than when rates are high.”
