Financial institutions play a critical role in the economy by facilitating the flow of money, credit, and investment. They act as intermediaries between savers and borrowers, businesses and consumers, and governments and investors. Understanding what financial institutions are, the types that exist, and the services they offer can help individuals and businesses make informed financial decisions. This article delves into the key aspects of financial institutions, providing a comprehensive overview of their roles and functions.

What Are Financial Institutions?

Financial institutions are organizations that provide financial services to individuals, businesses, and governments. They serve as intermediaries in the financial system by mobilizing funds from those who have excess capital (savers) to those who require funds (borrowers). These institutions facilitate payments, investments, lending, risk management, and capital formation.
