This paper presents multifactor Keynesian models of the long-term interest rate. In recent years there have been a proliferation of empirical studies based on the Keynesian approach to interest rate modeling. However, standard multifactor models of the long-term interest rate in quantitative finance have not been yet incorporated Keynes’s insights about interest rate dynamics. Keynes’s insights about the influence of the current short-term interest rate are introduced in two different multifactor models of the long-term interest rate to illustrate how the long-term interest rate relates to the short-term interest rate, the central bank’s policy rate, inflation expectations, the central bank’s inflation target, volatility in financial markets, and Wiener processes.

This paper presents empirical models of Mexican government bond (MGB) yields based on monthly macroeconomic data. The current short-term interest rate has a decisive influence on MGB yields, after controlling for inflation and growth in industrial production. John Maynard Keynes claimed that government bond yields move in lockstep with the short-term interest rate. The models presented in the paper show that Keynes’s claim holds for MGB yields. This has important policy implications for Mexico. The empirical findings of the paper are also relevant for ongoing debates in macroeconomics.

This paper relates Keynes’s discussions of money, the state theory of money, financial markets, investors’ expectations, uncertainty, and liquidity preference to the dynamics of government bond yields for countries with monetary sovereignty. Keynes argued that the central bank can influence the long-term interest rate on government bonds and the shape of the yield curve mainly through the short-term interest rate. Investors’ psychology, herding behavior in financial markets, and uncertainty about the future reinforce the effects of the short-term interest rate and the central bank’s monetary policy actions on the long-term interest rate. Several recent empirical studies that examine the dynamics of government bond yields substantiate the Keynesian perspective that the long-term interest rate responds markedly to the short-term interest rate. These empirical studies not only vindicate the Keynesian perspective but also have relevance for macroeconomic theory and policy.

This paper analyzes the nominal yields of UK gilt-edged securities (“gilts”) based on a Keynesian perspective, which holds that the short-term interest rate is the primary driver of the long-term interest rate. Quarterly data are used to model gilts’ nominal yields. These models bring to light the complex dynamics relating the nominal yields on gilts to the short-term interest rate, inflation, the growth of industrial production, and the government debt ratio. The results show that the short-term interest rate has a crucial influence on the nominal yields on gilts, even after controlling for various factors. Contrary to widely held views, a higher government debt ratio does not lead to higher nominal yields.

Keynes argued that the short-term interest rate is the main driver of the long-term interest rate. This paper empirically models the relationship between short-term interest rates and long-term government securities yields in Canada, after controlling for other important financial variables. The statistical analysis uses high-frequency daily data from 1990 to 2018. It applies both the cointegration technique and Granger causality within the vector error correction (VEC) framework. The empirical results suggest that the action of the monetary authority is an important determinant of Canadian government securities yields, which supports the Keynesian perspective. These findings have important implications for investors, financial analysts, and policymakers.

Nominal yields for Japanese government bonds (JGBs) have been remarkably low for several decades. Japanese government debt ratios have continued to increase amid a protracted period of stagnant nominal GDP, low inflation, and deflationary pressures. Many analysts are puzzled by the phenomenon of JGBs’ low nominal yields because Japanese government debt ratios are elevated. However, this paper shows that the Bank of Japan’s (BoJ) highly accommodative monetary policy is primarily responsible for keeping JGB yields low for a protracted period. This is consistent with Keynes’s view that the short-term interest rate is the key driver of the long-term interest rate. This paper also relates the BoJ’s monetary policy and economic developments in Japan to the evolution of JGBs’ long-term interest rates.

This paper analyzes the dynamics of long-term US Treasury security yields from a Keynesian perspective using daily data. Keynes held that the short-term interest rate is the main driver of the long-term interest rate. In this paper, the daily changes in long-term Treasury security yields are empirically modeled as a function of the daily changes in the short-term interest rate and other important financial variables to test Keynes’s hypothesis. The use of daily data provides a long time series. It enables the extension of earlier Keynesian models of Treasury security yields that relied on quarterly and monthly data. Models based on higher-frequency daily data from financial markets—such as the ones presented in this paper—can be valuable to investors, financial analysts, and policymakers because they make it possible for a real-time fundamental assessment of the daily changes in long-term Treasury security yields based on a wide range of financial variables from a Keynesian perspective. The empirical findings of this paper support Keynes’s view by showing that the daily changes in the short-term interest rate are the main driver of the daily changes in the long-term interest rate on Treasury securities. Other financial variables, such as the daily changes in implied volatility of equity prices and the daily changes in the exchange rate, are found to have some influence on Treasury yields.

An Empirical Analysis

The short-term interest rate is the main driver of the Commonwealth of Australia government bonds’ nominal yields. This paper empirically models the dynamics of government bonds’ nominal yields using the autoregressive distributed lag (ARDL) approach. Keynes held that the central bank exerts decisive influence on government bond yields because the central bank’s policy rate and other monetary policy actions determine the short-term interest rate, which in turn affects long-term government bonds’ nominal yields. The models estimated here show that Keynes’s conjecture applies in the case of Australian government bonds’ nominal yields. Furthermore, the effect of the budget balance ratio on government bond yields is small but statistically significant. However, there is no statistically discernable effect of the debt ratio on government bond yields.

This paper undertakes an empirical inquiry concerning the determinants of long-term interest rates on US Treasury securities. It applies the bounds testing procedure to cointegration and error correction models within the autoregressive distributive lag (ARDL) framework, using monthly data and estimating a wide range of Keynesian models of long-term interest rates. While previous studies have mainly relied on quarterly data, the use of monthly data substantially expands the number of observations. This in turn enables the calibration of a wide range of models to test various hypotheses. The short-term interest rate is the key determinant of the long-term interest rate, while the rate of core inflation and the pace of economic activity also influence the long-term interest rate. A rise in the ratio of the federal fiscal balance (government net lending/borrowing as a share of nominal GDP) lowers yields on long-term US Treasury securities. The short- and long-run effects of short-term interest rates, the rate of inflation, the pace of economic activity, and the fiscal balance ratio on long-term interest rates on US Treasury securities are estimated. The findings reinforce Keynes’s prescient insights on the determinants of government bond yields.
 

This paper investigates the determinants of nominal yields of government bonds in the eurozone. The pooled mean group (PMG) technique of cointegration is applied on both monthly and quarterly datasets to examine the major drivers of nominal yields of long-term government bonds in a set of 11 eurozone countries. Furthermore, autoregressive distributive lag (ARDL) methods are used to address the same question for individual countries. The results show that short-term interest rates are the most important determinants of long-term government bonds’ nominal yields, which supports Keynes’s (1930) view that short-term interest rates and other monetary policy measures have a decisive influence on long-term interest rates on government bonds.

This paper investigates the long-term determinants of Indian government bonds’ (IGB) nominal yields. It examines whether John Maynard Keynes’s supposition that short-term interest rates are the key driver of long-term government bond yields holds over the long-run horizon, after controlling for various key economic factors such as inflationary pressure and measures of economic activity. It also appraises whether the government finance variable—the ratio of government debt to nominal income—has an adverse effect on government bond yields over a long-run horizon. The models estimated here show that in India, short-term interest rates are the key driver of long-term government bond yields over the long run. However, the ratio of government debt and nominal income does not have any discernible adverse effect on yields over a long-run horizon. These findings will help policymakers in India (and elsewhere) to use information on the current trend in short-term interest rates, the federal fiscal balance, and other key macro variables to form their long-term outlook on IGB yields, and to understand the implications of the government’s fiscal stance on the government bond market.

US government indebtedness and fiscal deficits increased notably following the global financial crisis. Yet long-term interest rates and US Treasury yields have remained remarkably low. Why have long-term interest rates stayed low despite the elevated government indebtedness? What are the drivers of long-term interest rates in the United States? John Maynard Keynes holds that the central bank’s actions are the main determinants of long-term interest rates. A simple model is presented where the central bank’s actions are the key drivers of long-term interest rates through short-term interest rates and various monetary policy measures. The empirical findings reveal that short-term interest rates, after controlling for other crucial variables such as the rate of inflation, the rate of economic activity, fiscal deficits, government debts, and so forth, are the most important determinants of long-term interest rates in the United States. Public finance variables, such as government fiscal balances or government indebtedness, as a share of nominal GDP appear not to have any discernable effect on long-term interest rates.

Long-term interest rates in advanced economies have been low since the global financial crisis. However, in the United States the Federal Reserve could begin to hike its policy rate, the federal funds target rate, before the end of the year. In the United Kingdom, the Bank of England could follow suit. What is the outlook for global long-term interest rates? What are the risks around interest rates? What can policymakers do to cure the malady of low interest rates? It is argued that global interest rates are likely to stay low in the remainder of this year and the first half of next year due to a combination of domestic and international factors, even if a few central banks gradually begin to tighten monetary policy. The cure for this malady lies in proactive fiscal policy and measures to support job growth. Boosting effective demand and promoting higher wages and real disposable income would help lift inflation rates close to their targets and raise long-term interest rates.

John Maynard Keynes held that the central bank’s actions determine long-term interest rates through short-term interest rates and various monetary policy measures. His conjectures about the determinants of long-term interest rates were made in the context of advanced capitalist economies, and were based on his views on ontological uncertainty and the formation of investors’ expectations. Are these conjectures valid in emerging markets, such as India? This paper empirically investigates the determinants of changes in Indian government bonds’ nominal yields. Changes in short-term interest rates, after controlling for other crucial variables such as changes in the rates of inflation and economic activity, take a lead role in driving changes in the nominal yields of Indian government bonds. This vindicates Keynes’s theories, and suggests that his views on long-term interest rates are also applicable to emerging markets. Higher fiscal deficits do not appear to raise government bond yields in India. It is further argued that Keynes’s conjectures about investors’ outlooks, views, and expectations are fairly robust in a world of ontological uncertainty.
