Step 1: Contextualizing the role as "Banker to the Government".
The RBI Act establishes the central bank as the primary fiscal agent and banker for the Union Government. This role ensures that the sovereign's financial needs and monetary stability are managed by a professional institution.
Step 2: Operational banking services.
The RBI maintains the accounts of the government, accepting deposits and processing payments. It manages the inflow of tax revenues and handles the outflow of government expenditure, functioning essentially as a commercial bank does for an individual.
Step 3: Debt and Portfolio management.
The RBI manages the public debt by issuing new government bonds and treasury bills. It ensures the government can borrow from the market at reasonable rates and handles the repayment of interest and principal to creditors.
Step 4: Advisory and Agency role.
Beyond basic banking, the RBI provides expert advice to the government on economic policy, resource mobilization, and financial planning, ensuring that fiscal policy remains aligned with monetary objectives.
