What it means
Under monetary nominalism, a unit of money is whatever the law says it is. A dollar owed is a dollar paid, whatever it can buy at the time of payment.
The law does not usually adjust debts for changes in the price level. This keeps contracts simple and predictable.
Both parties know exactly how many units will change hands, and a court can enforce them without arguing about price indices. The cost is that the real burden of the debt changes with inflation, even though the written amount does not.
When prices rise, a borrower repays with money that has lost value, which helps the borrower and harms the lender. When prices fall, the reverse happens, and debts become heavier in real terms.
This is one reason lenders ask for higher interest rates when they expect inflation to be high. Business has found ways to work around the principle.
Index-linked contracts, inflation-protected bonds and rent agreements with annual increases tied to a price index all adjust the nominal amounts to follow prices. These deliberately depart from nominalism to share the inflation risk between the parties.
Finance teams meet the principle in everyday decisions. Long-term fixed-rate debt is attractive during periods of rising prices, because repayments are fixed in nominal terms.
Fixed-price supply contracts can become painful for the supplier if costs rise faster than expected. The word is also used in other fields, such as philosophy, where it describes a different idea about whether general categories exist.
In finance, the meaning to remember is the money one: debts are paid in the nominal amount agreed.
In practice
Real-world examples.
Example
A company borrows $2,000,000 at a fixed rate to build a factory. Over ten years prices in the economy rise sharply. The company repays the loan in dollars that are worth less than when it borrowed them, which helps its finances. The lender, by contrast, receives less purchasing power than it expected.
Example
A pension fund buys inflation-linked bonds so that the amounts owed grow with prices. This deliberately departs from nominalism. The fund uses the bonds to match its obligation to pay pensions that rise with inflation. The bonds cost more than ordinary bonds because the protection has a price.
Example
A landlord signs a ten-year lease at a fixed rent of $5,000 a month with no inflation clause. After several years of rising costs, the rent is worth less in real terms. The landlord negotiates a rent review clause in the next lease. The tenant accepts annual increases tied to a published price index.
Formula
Calculation
Real value of repayment = nominal repayment / (1 + cumulative inflation)
A lender lends $10,000 for five years and is repaid exactly $10,000. Over the five years, prices rise by a total of 20%. Real value of the repayment = 10,000 / 1.20 = $8,333.33, so the lender has lost $1,666.67 of purchasing power, which is the borrower's gain.Case study
Seen in the real world.
Ashbourne Engineering is a fictional firm that signed a fixed-price contract to supply machinery parts for $4,000,000 a year for five years. In this illustrative story, prices for steel and labour rose about 25% over the period. Because the contract was fixed in nominal dollars, the firm could not pass on the increased costs.
The firm's margin shrank from 12% to a loss in the last two years. Its finance director then introduced a rule that all contracts longer than one year must include a price adjustment clause linked to a published index. She explained to the board that the loss was a direct result of nominalism, since the written dollar amount stayed the same while its value fell.
Ashbourne has since renegotiated its older contracts where possible. For new work it uses an index published by the national statistics office and reviews prices every year. The finance director says the lesson is to treat any fixed nominal price over several years as a bet on inflation.
Watch out
Common mistakes.
- Assuming a debt is automatically adjusted for inflation. Unless the contract says so, the nominal amount is what must be repaid.
- Thinking nominalism only helps borrowers. Falling prices make debts harder to repay, so the effect can reverse.
- Confusing the finance meaning with the philosophical meaning. They share a name but refer to different ideas.
Questions
People also ask.
What is monetary nominalism in simple terms?
It is the rule that debts are paid in the face amount of money agreed, not in an amount adjusted for its purchasing power.
How can contracts avoid its effects?
They can include index-linked payments, price adjustment clauses or inflation-protected instruments.
Why do lenders care about it?
Because inflation reduces the real value of repayments, so they charge higher interest or ask for protection when inflation is expected.
