Banking is the system of financial intermediation through which licensed institutions accept deposits, extend credit, and provide payment and related services to individuals, businesses, and governments. Banks transform short-term deposits into longer-term loans, manage liquidity and risk, and operate the payment rails that move money through the economy. As a regulated, systemically important sector, banking sits at the centre of monetary policy transmission and financial stability.
