Why do we need banks?
The short answer
Banks accept deposits, connect payments, and lend funds to people and organizations that need them. They help move money between savers, borrowers, and sellers.
Deposits and lending
A deposit is money a bank must repay according to the account's terms. Banks manage deposits and use part of their funds for loans and investments, while keeping enough liquidity to meet expected withdrawals.
Payment infrastructure
Bank accounts support more than cash storage. They connect transfers, payroll, cards, and electronic payments. Banking services and deposit-protection rules differ by country, so check the rules that apply where you live.
