An ultra-affluent family can establish a family bank using the Infinite Banking Concept (IBC) by leveraging dividend-paying whole life insurance policies. This approach creates a self-sustaining financial system offering liquidity, growth, and tax advantages. Before implementation, the family should study resources like Nelson Nash’s “Becoming Your Own Banker” and consult with financial advisors familiar with IBC. The next step involves selecting a reputable mutual life insurance company and working with an experienced agent to structure policies that maximize cash value. The family can purchase policies for key members, ensuring early high cash value to provide liquidity. They can borrow against the cash value for family needs, like business ventures or education, while repaying loans with interest to grow the policies. These policies also serve as a valuable estate planning tool, providing tax-free inheritance and preserving wealth for future generations.
