Fiscal Policy: Spending, Taxes and Government Borrowing

A steel-blue government building, graphite receipt tile and silver coins represent public spending, taxes and borrowing.

In a fictional budget, the annual shortfall falls from $20 billion to $10 billion. The government's debt still rises.

The government needs less money to fill the gap, but there is still a gap to fill.

Reading fiscal news starts with two distinctions: what the number measures, and who made the decision. A tax cut, a Treasury bond sale and a Fed rate cut do different jobs.

Who decides taxes and spending

Fiscal policy means government decisions about taxes and spending. In the US federal government, Congress and the president's administration set those policies. Treasury handles the government's borrowing and cash.

Changing a tax or paying for a new bridge is fiscal policy. Changing the target for the federal funds rate is a Federal Reserve monetary-policy decision. The Fed can change borrowing conditions; it cannot pass a tax cut.

GDP's government component counts government consumption and investment. The budget also includes transfers, such as benefit payments, and interest. A budget dollar is not automatically a dollar in GDP's government component.

A deficit is a flow, debt is a stock

Budget receipts are revenue collected during a period, mainly taxes. Borrowed money does not count as revenue. Budget outlays are spending during that period. A budget deficit is the amount by which outlays exceed receipts.

Budget deficit=Outlays − Receipts

Take a small fictional government. In one year, it spends $120 billion and collects $100 billion: 120 − 100 = a $20 billion deficit. A negative result means a budget surplus: receipts exceed outlays.

Debt is borrowing still outstanding at a date. The deficit is a flow, measured over time; debt is a stock, measured at a point in time. Here, stock means an accumulated amount, not an equity share.

Follow it through two years. Amounts are billions of nominal dollars, without adjusting for inflation. Interest is included in spending; every deficit is financed by borrowing, cash stays fixed, and no other financing adjustments occur.

ItemYear AYear B
Annual receipts100110
Annual outlays120120
Annual deficit2010
Opening debt400420
Closing debt420430

In Year A, debt reaches $420 billion: 400 + 20. In Year B, it reaches $430 billion: 420 + 10. The deficit falls 50%, while debt rises another $10 billion.

The government adds less to what it owes. It has not started paying the total down.

How Treasury borrowing fits

Treasury borrows by issuing securities: investors provide funds in exchange for a promise of repayment. It sells bills, notes and bonds through public auctions.

Borrowing also replaces debt that comes due. In Year B, suppose $50 billion of principal needs repaying and new securities sell at face value, their principal amount. Issuing $60 billion pays off that $50 billion and covers the $10 billion deficit.

Gross issuance is the full amount sold. Net borrowing is what remains after principal repayments: $60 billion − $50 billion = $10 billion. Most of the money raised here replaces old debt.

Only $10 billion of $60 billion adds to debt
Year B · nominal $ billions
Illustrative Year B borrowing: $60 billion issued − $50 billion repaid = $10 billion added to debt.

Repaying principal is a financing transaction, not another budget outlay. Interest is the cost of borrowing and belongs in outlays.

The Fed can separately buy an existing Treasury security from an investor. Its payment goes to that seller. Treasury still owes the debt; changing the holder neither approves a spending program nor cancels the obligation.

How policy reaches a business

Government purchases create demand for suppliers. Taxes and transfers change the money households and firms have available.

Suppose a tax cut leaves your household with an extra $200 after tax. You can spend it, save it or repay debt. A $200 tax benefit is not automatically $200 of new shopping.

For Harbor Coffee, our fictional coffee business, a tax cut reaching customers could lift sales; a change in business taxes could change the cash it keeps.

Who gets the money matters, as does whether the policy is temporary or lasting. With idle workers and equipment, extra demand can raise output. Near capacity, more of the pressure can appear in prices. Government investment in roads or research can also expand what the economy can produce in the future.

Sustained additional government borrowing competes with businesses for funding. It can push interest rates up and make private investment harder to finance. Saving, money coming from abroad, demand for Treasuries and the Fed's response also shape rates. Higher borrowing costs can squeeze businesses, but borrowing totals alone cannot predict a stock's return.

What a deficit headline leaves out

A deficit can grow without lawmakers changing a single rule. In a weaker economy, taxable income can fall while more people qualify for benefits. These are automatic stabilizers: tax receipts and benefit spending adjust with the economy, cushioning the downturn without new legislation.

A falling deficit can even accompany a tax cut. Say Year B would have collected $115 billion without a tax cut, with spending still at $120 billion. The cut leaves the $110 billion in our table. The deficit is $10 billion instead of $5 billion, even though it fell from last year's $20 billion.

The policy's effect is the difference from what would have happened without it. Comparing two annual deficits answers a different question.

A proposal is still a plan; an enacted policy is law. Its price tag needs a time frame: $10 billion over one year differs from $10 billion over ten. Who receives or pays the money, and when the change takes effect, tells you which businesses might feel it.

For Harbor, a possible sales boost still depends on whether its customers get the tax benefit and spend it. The jobs report adds evidence about employment and pay.

In short

  • Lawmakers set taxes and spending; the Fed uses monetary-policy tools.
  • A deficit is a shortfall over a period; debt is the borrowing still outstanding at a date.
  • A smaller deficit can still add to debt, while gross issuance also replaces borrowing that comes due.
  • A Fed purchase of existing debt pays the seller and leaves Treasury's obligation intact.
  • A deficit can change without lawmakers changing tax or spending rules.
  • More money in customers' pockets need not mean more sales for Harbor.
