An interest-rate target above zero exacerbates inequality.

If a central bank sets its target rate to anything greater than zero, it further exacerbates inequality. It causes millions to become (or remain) unemployed, while at the same time, giving the already-rich more risk-free interest income. This post describes how and why this is true. Although it focuses on the United States and its central bank (the Federal Reserve), much of it applies to all developed (fully financially sovereign) nations.

Important correction

An important correction, which I need time to better integrate into this post: Rather than “a target rate above zero further exacerbates inequality” it should read “a target rate above the interest paid directly on reserves exacerbates inequality.” Currently the latter happens to be zero, but it doesn’t have to be. The Mosler-Forstater paper describes why, but I didn’t truly understand it until I read this (admittedly more advanced) 2006 paper by Scott Forstater: Interest Rates and Fiscal Sustainability.

The central bank stabilizes prices by “defending its interest rate.”

(The information in this post is substantially a result of my August 2020 interview with Joe Firestone: ELI5: What it means for the Federal Reserve to “defend its interest rate.”)

The United States Federal Reserve (the Fed) is unique among central banks in developed nations. It alone is mandated to manage not just price stability (inflation), but also the employment level (see Kelton 2020, chapter 2, note 15). Unfortunately, the Fed has decided that its primary directive is to manage inflation, and that it will adjust the level of employment to whatever is necessary in order to avoid it. In other words, the Fed, and therefore the United States, deliberately chooses for millions of its citizens to be unemployed, therefore choosing price stability only for some. (Not to mention that those who do the choosing are definitely not desperate for a job or a better job, and those whom they choose are farthest away from the levers of power.)

Congress could manage prices for all by implementing the job guarantee as recommended by MMT, but instead leaves the matter entirely to the “free market” and the Federal Reserve’s monetary policy. Unfortunately, it is impossible for the private-sector (for-profit businesses) to maintain full employment (Forstater 1999). This is primarily because for-profit businesses must remain profitable and must compete with other businesses that must also remain profitable. In economic downturns, they must shed workers in order to survive, which is exactly when workers (average citizens) are at their most desperate.

Only fully-financially-sovereign central governments can maintain full employment, even during economic downturns, because only they have no need for revenue or profit. In the words of PhD. economist John Harvey, “We are expecting [the private sector] to carry out a function that they are not designed to carry out” (2020).

The effects of setting the interest rate target to greater-than-zero.

The primary tool central banks use to manage inflation is to choose an interest rate to target and then “defend” that rate. The FOMC board decides on a rate (largely based on the ideology and guesswork of its members). It then announces the new rate and that it stands ready to purchase Treasuries at any quantity at any time, at the new rate. Since the Fed is part of the central government, it can greatly outbid even the largest entity or investor (Tymoigne 2014).

For an excellent and concise overview on the central bank’s target rate and why it should be permanently be set to zero, see the 2005 paper by Warren Mosler and Mathew Forstater, The Natural Rate of Interest Is Zero.

An interest rate greater than zero means banks must pay more for reserves when transacting in the interbank lending market (also called the banking reserve system). This causes banks to charge more for loans, which means companies take out fewer loans. This in turn increases the chance that the companies will shed workers, and who are the most likely to be shed but the disadvantaged and newly hired? The already unemployed and desperate-for-work will definitely not be hired, especially since they now have to compete with the ones just let go – those with obviously more, and more-recent, experience and skills. What it all means, is that when the Federal Reserve increases its interest-rate target, it always results in the disadvantaged being ejected from or further shut out of the job market. In other words, it keeps the poor, poor.

The Federal Reserve could defend its target rate by paying interest directly on reserves but they choose not to do that. As described in the Mosler-Forstater paper, the only other way to do it is to offer to sell bonds to the public. United States treasury bonds are interest bearing financial instruments that are, without exaggeration, 100% risk-free. As Warren calls them, bonds are “UBI for the rich.” In other words, a positive interest rate further enriches the rich.

Unfortunately, mainstream economics has asserted for decades that the primary cause of runaway, out-of-control inflation, is unemployment becoming too low. Because of this, the concept of full employment was long ago replaced with “maximum employment,” the latter of which means “as low as possible unemployment, as long as it does not trigger runaway inflation.” Therefore, according to this theory, it is paramount that the rate of unemployment not be allowed to drop below this threshold. That threshold is considered to be the “natural” rate of unemployment – and conversely, it is also the so-called maximum safe level of employment.

But the thing is, the runaway, out-of-control inflation they fear has never happened. So the rate of unemployment required in order to avoid it is anything but natural.

In December 2018, the Federal Reserve increased their target rate by .25 percent, which resulted in the disemployment of an additional 1.2 million Americans. .25 is almost zero. How can a number that small be so harmful? Conversely, the national debt is currently $26 trillion. How can a number that big not be harmful?
