Deficit

In a fiscal year the government takes in revenue and pays out outlays. If outlays are larger, the difference is the deficit for that year, and Treasury borrows to cover it.

The distinction from the debt is the single most common confusion in budget coverage. A falling deficit does not mean falling debt: it means the debt is growing more slowly. The debt only falls when there is a surplus.

A deficit is not automatically inflationary. Financed by taxes or by borrowing from the public, it rearranges who spends. Financed by creating money — the central bank buying the paper in size — it raises the quantity of money. That second path is the inflationary one. See debt vs. deficit and what causes inflation.

A worked example

In a fiscal year the government collects $5.0 trillion in revenue and pays out $6.8 trillion in outlays. The deficit is $1.8 trillion, and Treasury borrows that amount, so the debt rises by roughly $1.8 trillion. The next year the deficit falls to $1.5 trillion. That is a smaller deficit — and the debt still rises, by $1.5 trillion. A “falling deficit” and a “rising debt” describe the same year.

The only year in which the debt falls is one with a surplus: revenue above outlays. The illustrative figures here are round numbers; the real ones are on the national debt page with their stamps.

How to read it in coverage

“The deficit” with no year attached almost always means the current fiscal year, which runs from 1 October. “Reduced the deficit by $X over ten years” is a CBO-style figure against a baseline, not a change in any single year. And when a story says a policy “adds to the deficit”, it means the annual gap gets larger — the debt, which is the total, was going to rise regardless. “Deficits cause inflation” is incomplete until you ask how the gap was financed.
