    • Fixed Deposits – Fixed deposits come with a predetermined lock-in period. Fixed deposits are also referred to as time deposits as the funds are deposited for a specific time frame.

    • Current Deposits – Current deposits allow account holders to deposit and withdraw money whenever necessary. In some cases, current accounts also offer overdrafts until a pre-specified limit to individuals and businesses.

Commercial banks provide both secured and unsecured loans, categories are-

    • Cash Credit – Commercial Banks and its Functions include extending advances to individuals and organisations against bonds, inventories, and other types of securities. This facility, commonly known as cash credit, provides a more substantial sum when compared to other forms of credits.

1. Public Sector Banks

Public sector banks refer to a type of financial institution that is state-owned by the corresponding Government. A significant part of the share of such organisations is held by the Government. 

In India, the Reserve Bank of India, which acts as the central bank, creates operating guidelines for the public sector banks.
