Regional banks are financial institutions that operate within a specific geographic area, typically serving a smaller customer base compared to larger national banks. They offer a range of services, including personal and business banking, loans, and mortgages, often focusing on the needs of local communities. These banks play a crucial role in supporting local economies by providing credit to small businesses and individuals. They are often more accessible and responsive to local customers, fostering relationships that can lead to better service and tailored financial products.
