Financial institutions play important roles in the economy by facilitating transactions and allocating capital. They collect funds from savers and channel them to borrowers. This process of intermediation is crucial as it allows for maturity and risk transformation that individual investors cannot achieve. As major providers of credit and money supply, financial institutions also aid in transmitting monetary policy and supporting priority sectors. Their payment services and ability to pool investments make markets more efficient. However, their special functions are accompanied by regulation to ensure stability, fairness, and appropriate policy implementation.
