This paper econometrically models the dynamics of long-term Chinese government bond (CGB) yields based on key macroeconomic and financial variables. It deploys autoregressive distributive lag (ARDL) models to examine whether the short-term interest rate has a decisive influence on the long-term CGB yield, after controlling for various macroeconomic and financial variables, such as inflation or core inflation, the growth of industrial production, the percentage change in the stock price index, the exchange rate of the Chinese yuan, and the balance sheet of the People’s Bank of China (PBOC). The findings show that the short-term interest rate has an economically and statistically significant effect on the long-term CGB yield of various maturity tenors. John Maynard Keynes claimed that the central bank’s policy rate exerts an important influence over long-term government bond yields through the short-term interest rate. The paper’s findings evince that Keynes’s claim holds for China, implying that the PBOC’s actions are a driver of the long-term CGB yield. This means that policymakers in China have considerable leeway in fiscal and monetary operations, government deficit finance, and central government debt management.

This paper econometrically models Japanese yen (JPY)–denominated interest rate swap yields. It examines whether the short-term interest rate exerts an influence on the long-term JPY swap yield after controlling for several key macroeconomic variables, such as core inflation, the growth of industrial production, the percentage change in the equity price index, and the percentage change in the exchange rate. It also tests whether there are structural breaks in the dynamics of Japanese swap yields and related variables. The estimated econometric models show that the short-term interest rate exerts an important influence on the long-term swap yield in some periods but not in other periods in which core inflation exerts a marked influence on the swap yield. The findings from the econometric models reveal a discernable relationship between the call rate and the swap yield of different maturity tenors clearly held prior to April 2014 but did not in the subsequent period. These findings highlight the limits and scope of John Maynard Keynes’s contention that the central bank’s policy rate commands a decisive influence over the long-term market rate through the short-term interest rate. The policy implications of the estimated models’ results are discussed.

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.

There are several widely used benchmark models of the long-term interest rate in quantitative finance. However, these models have yet to incorporate Keynes’s valuable insights about interest rate dynamics. The Keynesian approach to interest rate dynamics can be readily incorporated in the benchmark models of the long-term interest rate. This paper modifies several benchmark interest rate models. In these modified models the long-term interest rate is related to the short-term interest rate and a Wiener process. The Keynesian approach to interest rate dynamics can be useful in addressing theoretical and policy issues.

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 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.

This paper models the dynamics of Japanese government bond (JGB) nominal yields using daily data. Models of government bond yields based on daily data, such as those presented in this paper, can be useful not only to investors and market analysts, but also to central bankers and other policymakers for assessing financial conditions and macroeconomic developments in real time. The paper shows that long-term JGB nominal yields can be modeled using the short-term interest rate on Treasury bills, the equity index, the exchange rate, commodity price index, and other key financial variables.

This paper empirically models the dynamics of Brazilian government bond (BGB) yields based on monthly macroeconomic data in the context of the evolution of Brazil’s key macroeconomic variables. The results show that the current short-term interest rate has a decisive influence on BGBs’ long-term interest rates after controlling for various key macroeconomic variables, such as inflation and industrial production or economic activity. These findings support John Maynard Keynes’s claim that the central bank’s actions influence the long-term interest rate on government bonds mainly through the short-term interest rate. These findings have important policy implications for Brazil. This paper relates the findings of the estimated models to ongoing debates in fiscal and monetary policies.

This paper presents a simple model of the long-term interest rate. The model represents John Maynard Keynes’s conjecture that the central bank’s actions influence the long-term interest rate primarily through the short-term interest rate, while allowing for other important factors. It relies on the geometric Brownian motion to formally model Keynes’s conjecture. Geometric Brownian motion has been widely used in modeling interest rate dynamics in quantitative finance. However, it has not been used to represent Keynes’s conjecture. Empirical studies in support of the Keynesian perspective and the stylized facts on the dynamics of the long-term interest rate on government bonds suggest that interest rate models based on Keynes’s conjecture can be advantageous.

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 employs a Keynesian perspective to explain why Japanese government bonds’ (JGBs) nominal yields have been low for more than two decades. It deploys several vector error correction (VEC) models to estimate long-term government bond yields. It shows that the low short-term interest rate, induced by the Bank of Japan’s (BoJ) accommodative monetary policy, is mainly responsible for keeping long-term JGBs’ nominal yields exceptionally low for a protracted period. The results also demonstrate that higher government debt and deficit ratios do not exert upward pressure on JGBs’ nominal yields. These findings are relevant to ongoing policy debates in Japan and other advanced countries about government bond yields, fiscal sustainability, fiscal policy, functional finance, monetary policy, and financial stability.

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.
 

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.

During the past two decades of economic stagnation and persistent deflation in Japan, chronic fiscal deficits have led to elevated and rising ratios of government debt to nominal GDP. Nevertheless, long-term Japanese government bonds’ (JGBs) nominal yields initially declined and have stayed remarkably low and stable since then. This is contrary to the received wisdom of the existing literature, which holds that higher government deficits and indebtedness shall exert upward pressures on government bonds’ nominal yields. This paper seeks to understand the determinants of JGBs’ nominal yields. It examines the relationship between JGBs’ nominal yields and short-term interest rates and other relevant factors, such as low inflation and persistent deflationary pressures and tepid growth. Low short-term interest rates, induced by monetary policy, have been the main reason for JGBs’ low nominal yields. It is also argued that Japan has monetary sovereignty, which gives the government of Japan the ability to meet its debt obligations. It enables the Bank of Japan to exert downward pressure on JGBs’ nominal yields by allowing it to keep short-term interest rates low and to use other tools of monetary policy. The argument that current short-term interest rates and monetary policy are the primary drivers of long-term interest rates follows Keynes’s (1930) insights.
