Public Debt

Public debt, also known as government debt or national debt, refers to the total accumulated amount of money that a government owes to creditors at a given point in time. It is a stock concept, meaning it represents the outstanding liabilities from past borrowings. Public debt arises when governments borrow funds (e.g., through bonds, loans, or treasury bills) to finance expenditures that exceed their revenues over multiple years. It includes both internal debt (owed to domestic lenders) and external debt (owed to foreign entities).

Key characteristics:

1. Measured as a total amount or as a percentage of GDP (e.g., debt-to-GDP ratio).
2. Accumulates over time due to repeated fiscal deficits, interest payments, and other factors like economic bailouts.
3. Governments service this debt by paying interest and principal, often by issuing new debt (rolling over).

Fiscal Deficit

Fiscal deficit is the difference between a government's total expenditure and its total revenue (excluding borrowings) in a single fiscal year. It is a flow concept, reflecting the annual shortfall that requires borrowing to bridge the gap. When revenues (from taxes, fees, etc.) fall short of spending (on welfare, infrastructure, salaries, etc.), the government incurs a fiscal deficit.

Key characteristics

1. Calculated annually, often as a percentage of GDP (e.g., targeting a 3-5% fiscal deficit).
2. Indicates the government's borrowing needs for that year to fund operations.
3. Can be influenced by economic cycles, policy decisions (e.g., tax cuts or stimulus spending), or unexpected events like recessions.
