National debt

Government debt (also known as public interest, national debt and sovereign debt) is the debt owed by a central government. (In federal states, "government debt" may also refer to the debt of a state or provincial, municipal or local government.) By contrast, the annual "government deficit" refers to the difference between government receipts and spending in a single year.

A central government with its own currency can pay for its spending by creating money ex novo. In this instance, a government issues securities not to raise funds, but instead to remove excess bank reserves (caused by government spending that is higher than tax receipts) and '...create a shortage of reserves in the market so that the system as a whole must come to the [central] Bank for liquidity.'

Governments create debt by issuing securities, government bonds and bills. Less creditworthy countries sometimes borrow directly from a supranational organization (e.g. the World Bank) or international financial institutions.

As the government draws its income from much of the population, government debt is an indirect debt of the taxpayers. Government debt can be categorized as internal debt (owed to lenders within the country) and external debt (owed to foreign lenders). Another common division of government debt is by duration until repayment is due. Short term debt is generally considered to be for one year or less, long term is for more than ten years. Medium term debt falls between these two boundaries. A broader definition of government debt may consider all government liabilities, including future pension payments and payments for goods and services the government has contracted but not yet paid.

During the Early Modern era, European monarchs would often default on their loans or arbitrarily refuse to pay them back. This generally made financiers wary of lending to the king and the finances of countries that were often at war remained extremely volatile.
