What Is It?
The banking system comprises institutions that accept deposits, make loans, and facilitate payments. Banks transform short-term deposits into long-term loans, creating credit and money in the process. They are the primary channel between savers and borrowers.
Origin
Banking dates to ancient Mesopotamia and medieval Italy. Modern banking evolved from goldsmiths issuing receipts. Central banking emerged to stabilize systems. The U.S. developed a dual system of federal and state charters. Post-2008 reforms strengthened regulation.
Why It Matters
Banks are essential for economic activity—channeling savings to investment, processing payments, and creating liquidity. Bank failures disrupt credit and payments. The system's stability is paramount for economic health. Understanding banking is essential for macro analysis.
Intermediate Level
Market Mechanics
Banks earn spread between deposit and loan rates. Fractional reserve banking creates money through lending. Types: commercial banks, investment banks, credit unions, shadow banks. Regulatory capital (CET1, Tier 1) constrains leverage. FDIC insures deposits.
How It Behaves
Banks expand credit in booms; contract in busts, amplifying cycles. Net interest margin drives profitability. Competition from fintech and shadow banks changes dynamics. Regulation post-2008 increased costs but reduced systemic risk. Digital disruption continues.
