The banking system is the network of commercial banks, central-bank arrangements, payment infrastructure, and supporting regulation through which deposits, credit, and settlement are organized.
Why economists use the system perspective
Looking at a single bank is not enough. Stability depends on the interactions among banks, funding markets, payment networks, and the central bank. That is why crises are often systemic rather than isolated.
What the system does
The banking system:
- channels savings into loans and investments,
- supports payments and clearing,
- transmits monetary policy,
- shares and sometimes amplifies financial risk.
Why it matters in macroeconomics
When the banking system is healthy, it helps support spending and investment. When it is fragile, credit can contract sharply and panic can spread across institutions. That makes the banking system central to business cycles and crisis analysis.
