The primary purpose of a bank is to act as a financial intermediary, facilitating the flow of funds between savers and borrowers. Banks accept deposits from individuals and businesses, providing a safe place to store money while offering interest as a reward for saving. Additionally, banks make loans to borrowers, enabling them to finance investments, purchases, or operational needs. Through these services, banks contribute to economic stability and growth. They also offer various financial products, including checking and savings accounts, mortgages, and investment options, serving as essential institutions in the financial system.
