    About this ebook

    Monetary policy has increasingly become the focus of economists and investors. This report describes the factors driving interest rates across the economic cycle. Written by an experienced fixed income analyst, it explains in straightforward terms the theory that lies behind central bank thinking. Although monetary theory appears complex and highly mathematical, the text explains how decisions still end up being based upon qualitative views about the state of the economy.

    The text makes heavy use of charts of historical data to illustrate economic concepts and modern monetary history. The report is informal, but contains references and suggestions for further reading.

    This is the second report published by BondEconomics.

      Chapter 1  Overview

      1.1  Introduction

      This report offers an informal introduction to modern central bank watching, explaining why interest rates are raised and lowered across the business cycle. The objective is to illustrate the logic behind central bank decisions, without plunging into the mathematical complexity of modern monetary economic theory. Whenever possible, concepts are illustrated with charts of economic and financial time series.

      Although the author is a follower of post-Keynesian economics, this text focuses on mainstream economic theory (sometimes called neoclassical economic theory). The explanation for this is that the central bankers who set the policy rate are followers of mainstream theory, and so we need to understand that theory if we wish to understand their decisions.

      Therefore, if we want to understand why policy rates are administered the way that they are, we need to understand mainstream logic. One could imagine an alternative theory how interest rates ought to be set, but until central bankers adopt that theory, it tells us little about real world interest rate determination.

      The underlying theme of the analysis is somewhat pessimistic. Mainstream macroeconomic theory is highly mathematical, and seems to offer a precise understanding of the business cycle. Unfortunately, at the core of the theory there are a number of variables that are not directly measured, and the current values of those variables are uncertain. It is easy to explain historical events, since estimates of those variables can be pinned down. However, the clarity of explanations for historical developments is in sharp contrast to the quality of model-based forecasts. The usefulness of the mainstream analytical framework is that it provides a way of thinking about the business cycle, at the cost of fundamental uncertainty around the values of key variables.

      1.2  Post-World War II Interest Rate Trends

      Economies in the developed world have behaved in a quite different fashion after World War II when compared to earlier eras. The Gold Standard constrained government finances as well as the accepted norms of policymaking behaviour. (In the Gold Standard, governments fixed the value of their currency relative to the price of gold.) The Great Depression and World War II upset the economic consensus, with central governments imposing command economies in order to pursue all-out military production. Governments loosened their control of the economy after World War II, but welfare state programs left governments much bigger when compared to pre-1930s norms.

      Government finances also became less constrained. The Gold Standard gave way to the Bretton Woods system, whereby only foreign governments could convert their U.S. dollar holdings into gold. Since the United States had accumulated a significant proportion of the world’s gold reserves by 1945, gold convertibility did not pose a significant constraint upon the U.S. government’s actions. The fall in the ratio of gold reserves to the stock of U.S. dollars in circulation put the Bretton Woods system into question by the mid-1960s, which eventually led President Nixon to abandon the Bretton Woods system in the early 1970s when the constraints finally began to bite into domestic policy options. The developed world (outside of continental Europe, which clings to currency pegging orthodoxy) moved to a system of free-floating fiat currencies. The subject of how a free-floating currency opens up the options for fiscal policy for a central government is the subject of an earlier report – Understanding Government Finance.

      The chart above shows one side effect of the change in the policy environment, using Canada as an example. Before World War II, the price level was tied to gold prices, and it was relatively stable. In the modern era, policies have favoured a policy of steady inflation. The price level profiles of other developed countries were generally similar to that of Canada. (As discussed in Section 3.3, Japan’s inflation experience has been different.)

      The rise in inflation was politically unpopular, and policies changed to bring it under control. The standard explanation is that tight monetary policy (that is, high interest rates) under Fed Chairman Volcker (which was echoed by other developed central banks) finally changed the trend of inflation. This caused the dramatic peaks in policy interest rates (the Fed Funds rate in the United States) in the early 1980s, as shown below.

      This exaggerated rise in interest rates in the 1970s has since skewed views about the future path of interest rates. It is often described as a supercycle, as interest rates rose and fell during the business cycles, while following a general trend upward (until around 1980) and then lower. The focus of this report is the discussion of the cyclical movements of interest rates, without speculating upon the drivers of the supercycle.

      In recent years, with the policy rate reaching 0% in many countries, the focus has moved towards unorthodox monetary policy measures – such as Quantitative Easing, negative interest rates, and even helicopter money. This report largely avoids a discussion of these policies (although the effect of the zero bound on interest rates is discussed). One justification is that this text is introducing the framework for orthodox monetary policy measures, and that the unorthodox measures add too much complexity. The second justification is that the author believes that these unorthodox policies are largely ineffective, but the historical record is too short to justify that argument.

      Finally, this report is focused on developed countries with free-floating currencies and control of their central bank (currency sovereignty). This includes countries such as Australia, Canada, Japan, Sweden, the United Kingdom, and the United States. These countries face no risk of involuntary default, as I discussed in my earlier report Understanding Government Finance. Conversely, although the euro floats versus other currencies, the constituent nations have fixed their currencies against each other, and involuntary governmental default is a very real risk. As for the so-called developing countries, the analysis herein may be broadly applicable, but these countries often have different preoccupations than the developed countries. For example, the value of the currency is emphasized much more by policymakers, even when the currency is notionally floating. For stylistic reasons, this currency sovereignty assumption is not repeated throughout the text, but many statements made herein rely upon that qualification.

      The composition of the rest of this report is as follows.

      Chapter 2 provides an overview of the theoretical concepts used in discussing the business cycle. The bulk of the discussion uses mainstream concepts, tied together by the notion of a Taylor Rule. However, Section 2.9 discusses how post-Keynesian analysis diverges from the mainstream in this area. Later chapters are much less theoretical in nature.

      Chapter 3 gives a brief overview of post-1990 monetary history. It focuses on the United States, although there is a brief mention of the experience of some other developed countries in Section 3.3.

      Chapter 4 discusses how various financial markets react to interest rates cycles. The focus is on interest rate markets, but currencies are also discussed in Section 4.6.

      Chapter 5 turns to the most difficult part of the business cycle to analyse – recessions. The argument made here is that the well-known inability of the consensus to forecast recessions is not just bad luck or incompetence. Instead, it is an inherent property of the business cycle.

      Chapter 6 provides some brief concluding remarks, asking whether interest cycles in the future will follow the patterns of recent history.
