This lecture explains the essential functions of banks, different types of banks, how banks are regulated for safety, and key factors to consider when choosing a bank for personal or business needs.

What Is a Bank and Its Role

  • A bank is a financial institution that accepts deposits and makes loans.
  • Banks offer products like checking accounts, savings accounts, and certificates of deposit (CDs).
  • They serve as secure places for savings and sources for financing.
  • Banks help keep money circulating in the economy through lending activities.

Evolution and Services of Banks

  • Banking has existed since the 14th century, evolving in the range of financial products offered.
  • Basic services include checking accounts (for payments/withdrawals), savings accounts (interest-earning), and loan services.
  • Banks earn profit by charging higher interest rates on loans than they pay on deposits.
  • Traditional brick-and-mortar banks now compete with online-only banks.

Banking Regulations and Safety

  • U.S. banks are regulated at state and federal levels to ensure safety and compliance.
  • The FDIC insures deposits up to $250,000 per depositor, per bank, per account type.
  • The Dodd-Frank Act introduced stress tests for large banks to ensure financial stability after the 2008 crisis.

Types of Banks

  • Retail banks serve the general public with services like accounts, loans, and credit cards.
  • Commercial/corporate banks serve businesses with services such as cash management and business loans.
  • Investment banks assist corporations with mergers, acquisitions, and underwriting.
  • Central banks manage national monetary policy and do not serve the general public.

Banks vs. Credit Unions

  • Credit unions are nonprofit, member-owned institutions offering limited services but often lower fees and better rates.
  • Members of credit unions own shares and profits are reinvested for their benefit.

Deposit Safety and Insurance

  • FDIC insures bank deposits; customers are automatically covered.
  • The SIPC insures brokerage accounts for up to $500,000, including $250,000 for cash.

Choosing a Bank

  • Consider if you want business and personal accounts at the same or different banks.
