The problems that occurred with decentralized, unregulated banking which led Congress to decide that centralization and public control were essential for an efficient banking system include:
- Episodes of monetary mismanagement by banks
- Monopolization of the banking system
- Numerous private bank notes being used as currency
The option "Unjust government control of money" is not typically cited as a problem leading to the need for centralization; rather, it is often viewed as a consequence of the centralization efforts aimed at addressing the issues with unregulated banking.
