Fiscal policy refers to a sovereign government's use of public spending, taxation, and budget deficits or surpluses to influence aggregate macroeconomic demand, income distribution, employment levels, and economic growth.
Fiscal policy is determined by legislative bodies and executive administrations through annual budget appropriations, whereas Monetary Policy is conducted independently by Central banks (such as the Federal Reserve or European Central Bank)) via interest rate adjustments and open market operations.
Expansionary Fiscal Policy: Implemented during recessions to stimulate economic demand through increased government spending, direct stimulus transfers, or tax cuts.
Contractionary Fiscal Policy: Enacted to cool overheating economies, curb inflation, or restore sovereign debt sustainability through spending cuts and increased taxation.
The fiscal multiplier measures the change in national Gross Domestic Product (GDP) generated by a $1.00 change in government expenditure or tax revenue:
$$\text{Fiscal Multiplier} = \frac{[Delta](/Reference?tab=glossary&term=Delta) \text{GDP}}{\Delta \text{Government Spending}}$$
Key empirical findings from IMF and Federal Reserve economic literature:
In fiscal year 2023, the United States federal government collected $4.44 trillion in revenue (primarily individual income tax $2.18 trillion and payroll taxes $1.61 trillion) and expended $6.13 trillion, resulting in a $1.70 trillion federal deficit (6.3% of GDP).
Total US public national debt passed $34.0 trillion in 2024, with total debt-to-GDP exceeding 122% (and debt held by the public exceeding 99% of GDP).
As central banks raised interest rates to combat inflation, net interest payments on US government debt reached $658 billion in FY2023 and surpassed $890 billion in FY2024—exceeding total annual defense spending ($842 billion) and becoming the fourth-largest single expenditure item in the federal budget behind Social Security, Medicare, and Defense.
Automatic Stabilizers: Budget mechanisms that adjust automatically during business cycles without new legislation. During recessions, income tax revenues decrease as incomes drop, while safety-net outlays (unemployment insurance, Medicaid, SNAP benefits) increase automatically, dampening economic contraction.
US Debt Ceiling Crises: The US debt limit is a statutory cap imposed by Congress on total federal borrowing authority. It has been raised or suspended 78 times since 1960. Standoffs in 2011 led Standard & Poor's to downgrade the US sovereign credit rating from AAA to AA+, while the 2023 impasse led Fitch Ratings to issue a similar downgrade to AA+.
Monetary Sovereignty and Debt Limits: Sovereign nations borrowing in their own floating, fiat currency (e.g., United States, United Kingdom, Japan) face no nominal default risk because the central bank can monetize debt. Japan's public debt exceeds 260% of GDP, with the Bank of Japan purchasing over 50% of outstanding Japanese Government Bonds (JGBs) to anchor yield curves.
