Definition
Budget Deficit occurs when a government’s total spending exceeds the revenue it collects (mainly from taxes and fees) during a given fiscal period.
Why It Matters
Persistent budget deficits require governments to borrow money by issuing bonds or taking loans, which increases national debt. While deficits can stimulate the economy during recessions by supporting spending, large or sustained deficits may raise borrowing costs, increase interest obligations, and limit future fiscal flexibility.
Example
If a government collects $3 trillion in taxes but spends $3.5 trillion on programs, defense, infrastructure, and interest payments, it runs a $0.5 trillion budget deficit that must be financed through borrowing.
