In simple terms

Fiscal policy is what a government does with its budget: how much it spends, how much it taxes, and how much it borrows to cover the difference.

The IMF puts the purpose plainly. Governments use those powers to promote strong and sustainable growth and to reduce poverty.

How it works

There are two levers. A government buys goods and services directly. It also acts indirectly, through the level and types of taxes, the size and composition of spending, and the degree and form of its borrowing.

An expansionary stance adds to demand, through more spending or lower taxes. A contractionary stance pulls demand back, mainly through lower spending.

Much of this happens with nobody deciding anything. Automatic stabilizers are parts of the budget that move with the economy on their own: tax revenue falls in a downturn while unemployment benefits rise. The European Central Bank defines them as elements built into government revenues and expenditures that reduce fluctuations in activity without government action, and treats unemployment benefits as the most relevant one on the spending side.

Their strength differs by country. The ECB estimates the euro area stabilizer at 0.48, against 0.3 to 0.4 for the United States, reflecting larger government, more progressive taxes and more generous benefits in Europe. Belgium has the largest among euro area members, at 0.66.

Why it matters

Fiscal policy works directly. A central bank influences the economy at one remove, through interest rates. A finance ministry changes spending and taxes itself.

Timing is the weak point. Programs must be designed, procured and delivered, so discretionary measures arrive late, and they may outlive the need once conditions improve. Automatic stabilizers carry no such lag, which is why they do much of the work.

Debt sets the outer limit. Moderate deficits are sustainable while confidence holds, but the IMF warns that deficits growing too large and lingering too long can undermine that confidence and raise creditor doubts about repayment.

Where you’ll see it

• Annual budget statements and the tax changes announced in them.
• Stimulus packages passed during a recession.
• Credit rating commentary on a government’s deficit path.
• Arguments over whether to cut spending or raise taxes to close a gap.

Example

In a downturn, income tax receipts drop and unemployment payments rise with no new law passed. That is fiscal policy already at work, before any package reaches a vote.

Often confused with

Monetary policy. Monetary policy belongs to the central bank and runs through interest rates and related tools. Fiscal policy belongs to the government and runs through the budget.
