Budgetary deficits must be financed by taxation, borrowing or printing money.Governments have mostly relied on borrowing, giving rise to what is called government debt.The concepts of deficits and debt are closely related. Deficits can be thought of as a flow which adds to the stock of debt. If the government continues to borrow year after year, it leads to the accumulation of debt and the government has to pay more and more by way of interest. These interest payments themselves contribute to the debt.
