Government debt is no longer just a line on a balance sheet. It carries direct consequences for the purchasing power of the money in your pocket and your bank account.
As of 20 August 2026, official U.S. Treasury figures put total federal debt above US$40.04 trillion. Australia faces its own expanding burden, with gross government debt already well into the trillion-dollar range and continuing to climb according to the 2026–27 Federal Budget forecasts. These numbers matter because of how modern governments actually finance their spending.
How Governments Really Pay for Spending
Governments fund expenditures primarily through taxation and borrowing. When tax revenue falls short, they issue debt. Monetary policy can—and often does—expand the money supply at the same time. Central banks can purchase government debt, inject reserves into the banking system, and enable further credit creation. The result is an increase in the quantity of money circulating in the economy.
Austrian economists have long insisted on a precise definition of inflation. Ludwig von Mises defined it as an increase in the quantity of money (including fiduciary media) that is not offset by a corresponding rise in the demand for money. The inevitable consequence is a fall in the purchasing power of the monetary unit. Rising prices are the symptom; the expansion of money is the cause.
When the supply of money grows faster than the economy’s real production of goods and services, each unit of currency buys less. Persistent deficits financed by monetary expansion accelerate this process. Murray Rothbard and other Austrian writers drew a clear distinction: deficits financed purely by borrowing from the public merely transfer existing money; deficits monetized through the banking system or central bank create new money and are therefore inflationary.
The Real Cost to Your Savings
This is not an abstract accounting exercise. If your savings account yields 2 percent while the expansion of money drives prices higher at 4 percent, your nominal balance may rise while your real purchasing power falls. The same $100 will command fewer goods and services in the future than it does today.
People holding large cash balances or keeping most of their wealth in purely nominal, currency-based assets are especially exposed. Money is never neutral. New money enters the economy at specific points—often first to governments, banks, and early recipients—and only later reaches the rest of the population. By the time it arrives, prices have already begun to adjust upward. This uneven process, sometimes called the Cantillon effect, redistributes real wealth from later receivers to earlier ones.
Protecting Purchasing Power
This is why investors look beyond cash. Assets that cannot be created at will by governments or central banks have historically offered better protection against the erosion of purchasing power. Gold and silver stand out because their supply is constrained by geology and mining costs rather than political decision. Property, shares in productive enterprises, and other scarce or real assets can also help preserve value over long periods, provided they are held as part of a diversified approach.
Austrian analysis has consistently favoured sound, commodity-based money precisely because it limits the ability of the state to dilute the currency. Under a fiat system, the incentive to expand the money supply remains strong whenever deficits grow and political pressures mount. Holding claims on real resources rather than pure nominal claims is one practical response available to individuals.
The Practical Lesson
Do not measure wealth solely by the number of currency units you hold. Ask what those units will actually buy in five, ten, or twenty years. When government debt continues to rise and is accompanied by monetary expansion, the purchasing power of money itself becomes a central risk. Building nominal balances is not enough; preserving and growing real purchasing power is the more durable objective.
