A Postal Savings Bank is a financial institution that offers savings accounts and other banking services, typically operated by a country's postal service. These banks aim to provide accessible banking options, especially in rural or underserved areas, where traditional banks may not be available. They often focus on promoting savings among the general public. In many countries, such as Japan and China, Postal Savings Banks have a long history and play a significant role in the financial system. They usually offer competitive interest rates and low fees, making them an attractive option for individuals looking to save money securely.
