National Debt, Interest Costs and Incentives

Published · Updated

Draft commentary, awaiting the publisher. Governments answer to incentives like anyone else, and the debt clock shows where they point.

The Treasury publishes the national debt to the penny every business day. The Gazette prints the latest stored figure in its Ledger, with the date and the source beside it. Few numbers in public life are so exact and so easy to ignore.

The claim

Governments respond to incentives the way households and firms do. Spending now is rewarded and the bill arrives later, often under someone else’s name. A debt that grows in good years and bad is not an accident or a failure of will. It is what the incentives produce.

That matters for the Federal Reserve because debt and money are tied together. A large borrower with a central bank next door is tempted to lean on it. The cleaner the wall between the two, the more honest the budget.

The strongest case against

Debt is not automatically a sin. A country that borrows in its own currency can roll its debt for a long time, and borrowing to fund real investment or to ride out a recession can pay for itself. Interest rates, not the headline total, decide whether the load is bearable, and the Treasury’s own average interest rate table shows how the cost of that borrowing moves.

Why the claim still holds

All of that is true, and none of it repeals the incentive. A borrower that faces no price signal borrows until the signal arrives. The signal is a higher rate at auction. The Treasury’s auction results show what buyers demanded, and they are one of the few honest checks on public spending we have.

Readers should do the arithmetic for themselves with the published numbers. Look at the debt, look at the average interest rate the Treasury pays, and ask what a rise in either does to the budget. The paper’s view is that the answer should shape how we think about the central bank’s independence, not just its rate.

This is the paper’s opinion. It reports no new figure, and it is not a finding of the Treasury or the Federal Reserve.
