The Interest Rate Question

Murray N. Rothbard’s “The Interest Rate Question” is a compact polemical essay rather than a systematic treatise. Its occasion is the rapid turn in opinion after Black Monday, when commentators shifted from assuming permanently high rates to expecting a downward trend. Rothbard treats this not as a forecasting mistake alone but as a failure to reason from economic law.

The Marxists call it “impressionism”: taking social or economic trends of the last few weeks or months and assuming that they will last forever.

The essay’s first move is methodological. Interest rates are not explained by a single headline, Fed purchase, panic, or exchange-rate story. They are prices in credit markets, formed by supply and demand, but also distorted by monetary intervention and expectations. Rothbard’s complaint against the financial press is that it notices individual mechanisms in isolation and then forgets the others.

In truth, interest rates, like any important price, are complex phenomena that are determined by several factors, each of which can change in varying, or even contradictory, ways.

Rothbard then distinguishes a genuine fall in rates from an artificial one. A sustainable decline arises when people save more and consume less, thereby making real resources available for investment. Bank credit expansion, by contrast, adds loanable funds through reserve creation and credit multiplication without any equivalent act of saving. It can make the loan market look as though society has become more future-oriented, while underlying consumption preferences remain unchanged.

The more they save, the lower the interest rate; the more they consume, the higher. Increased bank loans may mimic an increase in genuine savings, yet they are very far from the same thing.

This distinction anchors the essay’s Austrian business-cycle logic. When the banking system expands credit, it can push rates below their market level and validate longer, more capital-intensive projects. But the new money has not created the real savings required to complete those projects smoothly. When expansion slows, or when markets recognize the inflationary process, rates rise, asset prices weaken, and investments premised on cheap credit are exposed as malinvestments. The recession is therefore not an inexplicable break in prosperity; it is the correction of a boom built on a false signal.

Rothbard next explains why inflationary policy can first lower rates and later raise them. New bank credit initially increases the supply of credit, but as prices rise and the purchasing power of money falls, lenders demand compensation and borrowers accept higher nominal charges because repayment will occur in cheaper dollars. The same policy thus produces contradictory rate movements over time.

As prices rise, and as people begin to anticipate further price increases, an inflation premium is placed on interest rates.

The international section extends this reasoning to capital flows and exchange rates. Capital tends to move toward higher expected returns, so an attempt to hold domestic rates down under fiat money may put pressure on the dollar. If authorities defend the exchange rate, they may have to tolerate higher rates; if they allow depreciation, foreign creditors will eventually demand a premium for currency loss. Rothbard contrasts this with a gold-standard adjustment process and presents fiat policy management as a source of recurring policy crises.

The essay’s argument moves from journalistic short-termism to price theory, from price theory to the saving-credit distinction, and from there to the inflation premium and international monetary adjustment. Its broader claim is that modern policy obscures the coordinating role of interest by confusing real saving with credit creation. In Rothbard’s view, the difficulty is not that interest rates are inherently mysterious, but that government money and central banking make their signals unstable.

Without the interference of government, the entire topic would be duck soup.
