Since the economic crisis of 2008-2009, the Federal Reserve — America’s central bank — has expanded the money supply in the banking system by over $4 trillion, and has manipulated key interest rates to keep them so artificially low that when adjusted for price inflation, several of them have been actually negative. We should not be surprised if this is setting the stage for another serious economic crisis down the road.

Back on December 16, 2009, the Federal Reserve Open Market Committee announced that it was planning to maintain the Federal Funds rate — the rate of interest at which banks lend to each other for short periods of time — between zero and a quarter of a percentage point. The Committee said that it would keep interest rates “exceptionally low” for an “extended period of time,” which has continued up to the present.

Federal Reserve Policy and Monetary Expansion

Beginning in late 2012, the then-Fed Chairman, Ben Bernanke, announced that the Federal Reserve would continue buying US government securities and mortgage-backed securities, but at the rate of an enlarged $85 billion per month, a policy that continued until early 2014. Since then, under the new Federal Reserve chair, Janet Yellen, the Federal Reserve has been “tapering” off its securities purchases until in July of 2014, it was reduced to a “mere” $35 billion a month.

In her recent statements, Yellen has insisted that she and the other members of the Federal Reserve Board of Governors, who serve as America’s monetary central planners, are watching carefully macro-economic indicators to know how to manage the money supply and interest rates to keep the slowing general economic recovery continuing without fear of price inflation.

Some of the significant economic gyrations on the stock markets over the past couple of months have reflected concerns and uncertainties about whether the Fed’s flood of paper money and near zero or negative real interest rates might be coming to an end. In other words, borrowing money to undertake investment projects or to fund stock purchases might actually cost something, rather than seeming to be free.

When the media has not been distracted with the barrage of overseas crises, all of which seem to presume the need for America to play global policeman and financial paymaster to the world at US taxpayers’ expense, the presumption by news pundits and too many economic policy analysts is that the Federal Reserve’s manipulation of interest rates is a good, desirable and necessary responsibility of the central bank.

As a result, virtually all commentaries about the Fed’s announced policies focus on whether it is too soon for the Federal Reserve to raise interest rates given the state of the economy, or whether the Fed should already be raising interest rates to prevent future price inflation.

What is being ignored is the more fundamental question of whether the Fed should be attempting to set or influence interest rates in the market. The presumption is that it is both legitimate and desirable for central banks to manipulate a market price, in this case the price of borrowing and lending. The only disagreements among the analysts and commentators are over whether the central banks should keep interest rates low or nudge them up and if so by how much.

Market-Based Interest Rates Have Work to Do

In the free market, interest rates perform the same functions as all other prices: to provide information to market participants; to serve as an incentive mechanism for buyers and sellers; and to bring market supply and demand into balance. Market prices convey information about what goods consumers want and what it would cost for producers to bring those goods to the market. Market prices serve as an incentive for producers to supply more of a good when the price goes up and to supply less when the price goes down; similarly, a lower or higher price influences consumers to buy more or less of a good. And, finally, the movement of a market price, by stimulating more or less demand and supply, tends to bring the two sides of the market into balance.

Market rates of interest balance the actions and decisions of borrowers (investors) and lenders (savers) just as the prices of shoes, hats, or bananas balance the activities of the suppliers and demanders of those goods. This assures, on the one hand, that resources that are not being used to produce consumer goods are available for future-oriented investment, and, on the other, that investment doesn’t outrun the saved resources available to support it.

Interest rates higher than those that would balance saving with investment stimulate more saving than investors are willing to borrow, and interest rates below that balancing point stimulate more borrowing than savers are willing to supply.

There is one crucial difference, however, between the price of any other good that is pushed below that balancing point and interest rates being set below that point. If the price of hats, for example, is below the balancing point, the result is a shortage; that is, suppliers offer fewer hats than the number consumers are willing to buy at that price. Some consumers, therefore, will have to leave the market disappointed, without a hat in hand.

Central Bank-Caused Imbalances and Distortions

In contrast, in the market for borrowing and lending the Federal Reserve pushes interest rates below the point at which the market would have set them by increasing the supply of money on the loan market. Even though savers are not willing to supply more of their income for investors to borrow, the central bank provides the required funds by creating them out of thin air and making them available to banks for loans to investors. Investment spending now exceeds the amount of savings available to support the projects undertaken.

Investors who borrow the newly created money spend it to hire or purchase more resources, and their extra spending eventually starts putting upward pressure on prices. At the same time, more resources and workers are attracted to these new investment projects and away from other market activities.

The twin result of the Federal Reserve’s increase in the money supply, which pushes interest rates below that market-balancing point, is an emerging price inflation and an initial investment boom, both of which are unsustainable in the long run. Price inflation is unsustainable because it inescapably reduces the value of the money in everyone’s pockets, and threatens over time to undermine trust in the monetary system.

The boom is unsustainable because the imbalance between savings and investment will eventually necessitate a market correction when it is discovered that the resources available are not enough to produce all the consumer goods people want to buy, as well as all the investment projects borrowers have begun.

The Central Bank Produces Booms and Busts

The unsustainability of such a monetary-induced investment boom was shown, once again, to be true in the latest business cycle. Between 2003 and 2008, the Federal Reserve increased the money supply by at least 50 percent. Key interest rates, including the Federal Funds rate, and the one-year Treasury yield, were either zero or negative for much of this time when adjusted for inflation. The rate on conventional mortgages, when inflation adjusted, was between two and four percent during this same period.

It is no wonder that there emerged the now infamous housing, investment, and consumer credit bubbles that burst in 2008-2009. None of these would have been possible and sustainable for so long as they were if not for the Fed’s flood of money creation and the resulting zero or negative lending rates when adjusted for inflation.

The monetary expansion and the artificially low interest rates generated wide imbalances between investment and housing borrowing on the one hand and low levels of real savings in the economy on the other. It was inevitable that the reality of scarcity would finally catch up with all these mismatches between market supplies and demands.

This was, of course, exacerbated by the Federal government’s housing market creations, Fannie Mae and Freddie Mac. They opened their financial spigots through buying up or guaranteeing ever more home mortgages that were issued to a growing number of high-risk borrowers. But the financial institutions that issued and then marketed those dubious mortgages were, themselves, only responding to the perverse incentives that had been created by the Federal Reserve and by Fannie Mae and Freddie Mac.

Why not extend more and more loans to questionable homebuyers when the money to fund them was virtually interest-free thanks to the Federal Reserve? And why not package them together and pass them on to others, when Fannie Mae and Freddie Mac were subsidizing the risk on the basis of the “full faith and credit” of the United State government?

More Monetary Mischief in the Post-Bubble Era

What was the Federal Reserve’s response in the face of the busted bubbles its own policies helped to create? Between September 2008 and June 2014, the monetary base (currency in circulation and reserves in the banking system) has been increased by over 440 percent, from $905 billion to more than $4 trillion. At the same time, M-2 (currency in circulation plus demand and a variety of savings and time deposits) grew by 35 percent during this time period.

Why haven’t banks lent out more of this huge amount of newly created money, and generated a much higher degree of price inflation than has been observed so far? Partly, it is due to the fact that after the wild bubble years, many financial institutions returned to the more traditional credit-worthy benchmarks for extending loans to potential borrowers. This has slowed down the approval rate for new loans.

But more importantly, those excess reserves not being lent out by banks are collecting interest from the Federal Reserve. With continuing market uncertainties about government policies concerning environmental regulations, national health care costs, the burden of the Federal debt and other government unfunded liabilities (Social Security and Medicare), as well as other possible political interferences in the marketplace, banks have found it more attractive to be paid interest by the Federal Reserve rather than to lend money to private borrowers. And considering how low Fed policies have pushed down key market lending rates, leaving those excess reserves idle with first Ben Bernanke and now Janet Yellen has seemed the more profitable way of using all that lending power.

Even under the heavy-handed intervention of the government, markets are fundamentally resilient institutions that have the capacity to bounce back unless that governmental hand really chokes the competitive and profit-making life out of capitalism. Any real recovery in the private sector will result in increased demands to borrow that would be satisfied by all of that Fed-created funny money currently sitting idle. Once those hundreds of billions of dollars of excess reserves come flooding into the market, price inflation may not be far behind.

Central Banking as the Problem, Not the Solution

At the heart of the problem is the fact that the Federal Reserve’s manipulation of the money supply prevents interest rates from telling the truth: How much are people really choosing to save out of income, and therefore how much of the society’s resources — land, labor, capital — are really available to support sustainable investment activities in the longer run? What is the real cost of borrowing, independent of Fed distortions of interest rates, so businessmen could make realistic and fair estimates about which investment projects might be truly profitable, without the unnecessary risk of being drawn into unsustainable bubble ventures?

Unfortunately, as long as there are central banks, we will be the victims of the monetary central planners who have the monopoly power to control the amount of money and credit in the economy; manipulate interest rates by expanding or contracting bank reserves used for lending purposes; threaten the rollercoaster of business cycle booms and busts; and undermine the soundness of the monetary system through debasement of the currency and price inflation.

Interest rates, like market prices in general, cannot tell the truth about real supply and demand conditions when governments and their central banks prevent them from doing their job. All that government produces from its interventions, regulations, and manipulations is false signals and bad information. And all of us suffer from this abridgement of our right to freedom of speech to talk honestly to each other through the competitive communication of market prices and interest rates, without governments and central banks getting in the way.
