Intragovernmental Debt

An intragovernmental debt is money one part of the government owes to another part, typically when the Treasury borrows from trust funds like Social Security or Medicare. It is debt the government owes to itself, not to external creditors.

How intragovernmental debt forms

The US Treasury often spends more than it collects in taxes. It covers the gap by issuing Treasury securities that investors buy. But it also borrows from government trust funds.

The Social Security Trust Fund collects payroll taxes and uses them to pay retirees and the disabled. If payroll taxes exceed benefits in a given year, the surplus is invested in special Treasury securities. The government owes these funds money and pays statutory interest rates (set by law, currently around 2–3%).

Similarly, the Medicare Trust Fund, federal employee pension funds, and other accounts accumulate surplus revenue that is lent to the Treasury.

From the trust funds’ perspective, these Treasury securities are assets — a way to earn returns on excess revenue. From the Treasury’s perspective, they are debt.

Why intragovernmental debt matters (and why it might not)

Intragovernmental debt is part of the total national debt, so it is included in all official debt figures. However, it is fundamentally different from debt held by the public:

Default risk: The government is highly unlikely to default on intragovernmental debt because it controls both sides of the transaction. It owes itself.

Political commitment: Intragovernmental debt represents a promise the government makes to itself to repay future benefits. This is a real commitment, but it cannot trigger a credit crisis or investor panic.

Fiscal reality: Intragovernmental debt does commit future revenue. When the Social Security Trust Fund runs low (projected around 2034 in the US), the government will have to repay the borrowed funds or cut benefits. So the debt is not “harmless” — it reflects real future obligations.

The Social Security example

The Social Security system accumulated surplus revenue for decades, which it lent to the Treasury. As the Baby Boom generation retires, the system is shifting from surplus to deficit. The trust fund will need to call on the Treasury to repay the borrowed money, forcing the Treasury to either raise taxes, cut other spending, or increase public debt.

This is why intragovernmental debt, while low default risk, still matters for long-term fiscal planning.

Intragovernmental debt in balance sheets

In consolidated government accounts, intragovernmental debt is sometimes netted out — counted as both an asset (what the trust fund is owed) and a liability (what the Treasury owes). In this view, the debt cancels out and only debt held by the public remains as a net government liability.

However, cash-based budget accounting treats intragovernmental debt as real debt, because money flows from one account to another to service it.

Controversy and accounting debate

Some argue that intragovernmental debt should be removed entirely from deficit and debt discussions because it represents internal accounting entries, not real external obligations. Others argue it must be included because it represents genuine future liabilities — money the government has spent and must repay from future revenue.

The standard practice is to report both figures: national debt (which includes intragovernmental debt) and debt held by the public (which does not).
