- 1910 - The Postal Savings System was established by an Act of Congress. The system paid two percent interest per year. The legislation aimed to get money out of hiding, attract the savings of immigrants accustomed to saving at Post Offices in their native countries, provide safe depositories for people who had lost confidence in banks, and furnish more convenient depositories for working people. Initially, the minimum deposit was $1, and the balance in an account could not exceed $500, excluding interest. The system ended officially on July 1, 1967.
