Washington borrows. Investors collect interest. Taxpayers carry the bill.

Does collecting interest give investors a reason to want endless government debt? It is a fair question. But creditors also need two things: reliable repayment and money that keeps its value. Debt that threatens either can hurt the very people who lend to the government.

The larger question is what Americans lose when government borrowing competes with businesses for money and resources. Interest payments are easy to see. The factory or warehouse expansion that never gets built is much harder to see.

Who receives the interest?

When spending exceeds revenue, Treasury covers the gap by selling securities. These are essentially government IOUs. Investors hand over cash today in exchange for promised interest and repayment of the full amount at maturity.

The lenders include individual savers, banks, investment funds, pension funds, state and local governments, and foreign investors. If your retirement fund holds Treasury securities, you may receive some of that interest indirectly. Some Treasury debt is also held by government trust funds, such as Social Security's. That is a separate category, because it is money the government owes itself.

Interest is payment for lending money, for waiting, and for accepting risk. It is not free money. Lenders can lose purchasing power to inflation. Someone who sells a bond before maturity can lose money if prices have fallen.

Why rising rates can hurt existing bondholders

Suppose you buy a $1,000 Treasury bond paying 3% a year. It pays $30 annually. Treasury notes and bonds actually pay interest twice a year, but annual figures keep the math simple. This example is hypothetical.

Later, new bonds of similar safety offer 5%, or $50 a year on $1,000. Buyers now prefer the new bonds, and your older bond still pays only $30. If you want to sell it, you must lower its price so that a buyer earns roughly the current 5% on the smaller amount they pay. A fixed payment can lose market value this way.

If you hold the bond to maturity, you still receive your $30 each year and your $1,000 back, as long as Treasury pays as promised. The cost to you is that your money keeps earning the older, lower rate while new bonds pay more.

Inflation creates another problem. Suppose a basket of groceries costs $100 when you buy the bond. Your $1,000 could buy ten baskets. If the same basket later costs $125, your $1,000 repayment buys only eight. The dollar amount does not change, but what it can buy does. Your $30 in interest also buys fewer groceries. The same thing happens with housing, gasoline, and electricity. The grocery example is hypothetical.

So creditors have good reasons to want fiscal stability. Policies that fuel inflation or push market interest rates higher can hurt lenders even while they collect interest. Not all borrowing causes inflation. A balanced budget would stop adding new debt, but it would not erase existing bonds or guarantee the value of the dollar.

How government competes with businesses for money

Imagine investors have $100 million to lend at today's interest rates. Businesses want to borrow $80 million for equipment and expansion. Treasury wants $40 million to finance government spending.

Together, borrowers want $120 million, but only $100 million is available at those rates. This is a simplified example. The $100 million is not a fixed national supply. When demand for money exceeds supply, interest rates tend to rise. Higher rates attract more savers and make some borrowers drop out. Additional domestic saving and foreign investment can also add funds, and monetary policy matters too.

Why might investors pick Treasury? Its interest, its reputation for safety, and its ease of resale can all be attractive. An investor might prefer a safe 4% Treasury return to a riskier business loan paying 6%. Government does not have to offer the highest rate to win the money.

If Treasury borrows $40 million, $60 million is left for businesses. They must find more savings, offer better terms, scale back their plans, or postpone projects.

Consider a warehouse owner who borrows $1 million to expand. The expansion is expected to produce $60,000 a year in operating profit before paying for the loan. Assume an interest-only loan. The owner pays interest every year and repays the $1 million principal at the end. This example is hypothetical.

At 4%, interest is $40,000 a year. That leaves $20,000 before principal is repaid, so the project looks worthwhile. At 7%, interest is $70,000 a year, which is more than the expected operating profit. The owner may cancel the expansion.

Multiply that decision across many businesses, and the result is fewer equipment orders, fewer construction jobs, and less future capacity. Over time, slower business investment can slow productivity growth, because workers have fewer improved tools and technologies to work with.

Economists call this "crowding out." The Congressional Budget Office identifies increased federal borrowing as a source of upward pressure on interest rates and, over time, lower private investment. We explored the broader forces behind federal borrowing in our earlier post on what is driving America's debt.

Why private enterprise generally has an advantage

Businesses that compete for customers face a hard test. They must deliver something people value enough to buy, while keeping costs under control. Waste money, and competitors can undercut you. Disappoint customers, and they can leave. Lose money repeatedly, and investors may pull their support. Failure is a real consequence.

Research supports the idea that competition and accountability often improve performance. In "An Assessment of Privatization," published in 2004, Sunita Kikeri and John Nellis summarize an earlier review of approximately 50 studies by Mary Shirley and Patrick Walsh. Their summary found that privately owned or privatized firms generally outperformed government-owned enterprises, with the strongest evidence in competitive markets. The authors also note that governments often kept supporting insolvent enterprises, which weakened pressure to reform.

A simple example: a warehouse that buys better equipment might process 1,500 orders with the same staff that once handled 1,000. Lower costs per order can mean lower prices, higher wages, or profits available for new investment. This example is hypothetical.

But profit is not the same as social benefit, and private ownership does not automatically guarantee efficiency. A later review by Saul Estrin and Adeline Pelletier, published in 2018, emphasizes capable regulation, complementary reforms, and well-designed privatization. The strongest argument concerns commercial activity in competitive markets. These studies do not show that every government function should be privatized.

Spending money is not the same as creating value

When Treasury borrows and government spends, the money reaches contractors, employees, and other recipients. It keeps circulating through the economy.

But circulation alone does not tell us whether the spending was worthwhile. Gross spending counts every dollar that goes out. Net economic benefit asks what the spending produces, after considering what those same resources could have produced elsewhere.

Compare $1 million spent on productive warehouse equipment with $1 million spent replacing perfectly serviceable government furnishings. Both pay suppliers. In this example, only the equipment substantially improves future production.

Workers, materials, and machinery have alternative uses. Resources devoted to one project cannot also build another.

Some public spending is valuable. A useful bridge can improve commerce. Wasteful spending consumes resources without comparable benefits. The right test is whether a program's benefits justify its full cost, including the private investment it displaces.

Investors can earn interest on government debt while still wanting fiscal discipline. Americans should demand that discipline too. Excessive borrowing burdens taxpayers and can crowd out the investments that create jobs, raise productivity, and support prosperity.

Interest checks show who gets paid. The investments that never happen show what America loses.
