Revenue expenditure are kind of expenditures that are of consumptive kind and do not involve creation of productive assets. They are either used in running of a productive process or running a government.

• Law and order expenditures (i.e., police & paramilitary);
• Expenditures on social services (includes all social sector expenditures as education, health care, social security, poverty alleviation, etc.) and general services (tax collection, etc.);
• Grants given by the government to Indian states and foreign countries.

India was obliged to do so as per Article VIII of the IMF which prohibits any exchange restrictions on current international transactions (keep in mind that India was under preconditions of the IMF since 1991).
