Banking is the business of accepting deposits, supplying credit, facilitating payments, and intermediating between savers and borrowers.
Why banking matters
Banks do more than move money around. They create payment infrastructure, transform maturity, evaluate borrowers, and channel credit into households and firms. Because of those roles, changes in banking conditions can affect consumption, investment, and financial stability.
The basic economic functions
Banking typically combines:
- payments and settlement services,
- credit allocation,
- liquidity provision,
- risk transformation.
Those functions make banking central to both everyday transactions and the broader macroeconomy.
Why economists study banking
Banking matters because the sector sits between monetary policy and the real economy. When banks expand or contract lending, the effects can spread through employment, asset prices, and output.
