The scope for national monetary policy in the face of globalised financial markets

Conclusion Experience has shown that German monetary policy is far from impotent There is consequently no call for passive resignation. The monetary authorities must send clear signals if the current turbulence on the currency markets is to be kept in check. The Bundesbank itself has clearly shown — during the period following German Unification — that an autonomous monetary policy is possible in spite of the high degree of integration on international financial markets. It is hard to see why this should not be the case today simply because it is no longer interest rate hikes but base rate cuts that are called for.If interest rates are not reduced, the interest rate on the German capital market will continue to follow the lead set by American monetary policy. But is it right that the American central bank, on the basis of data on the state of the US economy, indirectly helps to determine whether new jobs are created in Germany and whether existing jobs are made more secure? What is required in the medium term is greater independence on the part of German monetary policy. The globalisation of financial markets does not stand in the way of such a strategy.     

Do central banks react to the stock market? The case of the Bundesbank

In this paper, we ask whether the Bundesbank, prior to the European Central Bank taking responsibility for monetary policy in 1999, reacted systematically to stock price movements. In contrast to the results for the US, our empirical findings show a generally weak relationship between German stock returns and short-term interest rates at the daily and the monthly frequency. The results are extremely robust to alternative model specifications. The evidence is inconsistent with the hypothesis of a systematic reaction of the Bundesbank to German stock prices. However, we do find that, as in the US, the Bundesbank may have reacted to the stock market crash of 1987 by loosening monetary policy.     

Information arrivals and intraday exchange rate volatility

This paper investigates the link between information arrivals and intraday DEM/$ volatility. Information arrivals are measured by the numbers of news items that appeared in the Reuters News Service. We separate news stories into different categories and find that total headline news counts, US and German macroeconomic news and German Bundesbank monetary policy news all have a significant impact on intraday DEM/$ volatility. The larger quantitative effects of the German Bundesbank monetary policy news and US macroeconomic news at 15-min intervals are consistent with the findings of a two-stage adjustment process of public information arrivals [Fleming and Remolona, J. Finance (1999) 1901]. Our results suggest that the persistent of intraday exchange rate volatility set off by public information is extended by traders’ private information about 15 min later. The conclusions are obtained from ARCH models that incorporate intraday seasonal volatility terms.     

Three aspects of the Swiss term structure: an empirical survey

The term structure is an important transmitter of, and indicator for, monetary policy. This paper studies the Swiss term structure using monthly data from 1989 to 2005. We study the impact of the new monetary policy strategy that the Swiss National Bank (SNB) adopted at the beginning of 2000 on three aspects of the term structure. First, we test the expectations hypothesis and find it confirmed at the short end of the yield curve. At the long end, time-varying term premia seem present. Second, we ask whether the yield curve contains information regarding future inflation and economic activity. We find that a steepening of the yield curve predicted an increase in economic activity in the short term before the change in policy strategy, but not thereafter. Third, we study the contemporaneous reaction of the term structure to macroeconomic conditions and conclude that the SNB’s commitment to stabilizing inflation may have become more credible after the change in the monetary policy strategy.      

U.S. Monetary Policy Surprises: Identification with Shifts and Rotations in the Term Structure

We develop a model to extract measures of monetary policy surprises from the maturity structure of the yield curve. The model endogenously allows for the fact that the yield curve may either shift or rotate in response to monetary policy shocks. A latent factor model approach with identification through heteroskedasticity harnesses the term structure to extract monetary policy shocks. The approach offers informational advantages over event studies. Results from the U.S. term structure from 1994 strongly support the hypothesis that differing term structure responses are reactions to different types of monetary policy shock, rather than differing reactions to the same policy shock.     

公开市场操作与利率期限结构行为——基于混频数据信息的研究视角

在混频数据信息环境中,精准识别公开市场操作(央行政策利率)和国债收益率曲线(基准利率体系)之间的关联机制至关重要,其影响了货币政策期限结构传导的有效性。本文在混频Nelson-Siegel(N-S)利率期限结构模型框架下,引入央行政策利率,揭示公开市场操作与利率期限结构(水平、斜率、曲度)因子之间的作用机制。实证结果表明:混频数据信息条件下,引入的公开市场操作信息显著改进国债收益率曲线的拟合效果;斜率因子冲击对公开市场操作具有显著的正向影响,而利率期限结构因子对政策调控的反应不敏感。进一步研究表明,2015年以来,公开市场操作对斜率因子的影响逐渐扩大,政策利率向国债收益率曲线的传导效率得到显著提高,我国现代货币政策框架日益健全。     

The impact of monetary policy surprises on asset return volatility: the case of Germany

This paper investigates the impact of monetary policy surprises by the FED or Bundesbank/ECB on the return volatility of German stocks and bonds using a GARCH-M model. We show that stock return volatility is susceptible to monetary policy surprises in the United States, whereas monetary policy surprises in the Euro zone matter for bond return volatility. These findings are robust for other Euro zone stock markets, but not significant for other Euro zone bond markets. The empirical evidence also suggests that monetary policy surprises have larger effects on German stock return volatility in bear markets than in bull phases. Moreover, our results support the claim that stock return volatility can be negatively correlated with stock returns, contradicting predictions made by many asset pricing models (e.g., CAPM or ICAPM) and the empirical finding of an insignificant relationship often reported in the literature.

Interest rate linkages within the EMS and bank credit supply

The exchange rates between the currencies of European Monetary System (EMS) members are essentially fixed between narrow bands mandated by the Exchange Rate Mechanism (ERM). the intent of such a fixed rate regime is to enhance policy co-ordination within the EMS. However, it has instead led to German policy dominance within the system according to several recent studies. We examine the optimal dynamic credit policy of a bank in an EMS country that is subject to such German ‘dominance’. Our stochastic control model reveals conditions under which German monetary policies can influence domestic bank lending behaviour. It also suggests that banks may be able to hedge such risk exposure by increasing in size. the model offers ‘credit supply' based explanations for recent regulatory reforms in Europe towards unified banking and the attempts of several EMS members to de-link their policies from that of the German Bundesbank.     

Interaction of Government Tiers and Central Banks in a Federation: An Empirical Test

Fiscal rules are necessary to protect monetary policy from the consequences of unsustainable or active fiscal policy for inflation. Monetary unions, such as the Economic and Monetary Union (EMU), require even stronger fiscal rules to avoid free riding by regional fiscal authorities on the common monetary policy. By contrast, in a fiscal federation, the federal government internalises the effect of active regional policies on the overall price level. Federal fiscal policy contributes to price stability either by enforcing fiscal rules or by adjusting its own stance. Following Canzoneri, Cumby and Diba (2001), we test whether federal and regional governments in Germany behave in an active or passive way. We find evidence of a spillover effect of unsustainable policies on other regions. The German federal government offsets the effect on the price level by running passive policies. The Bundesbank's prime objective of price stability is therefore endorsed by fiscal policy. The results have implications for the regulation of fiscal policies in the EMU.     

Monetary policy signaling and movements in the term structure of interest rates

This paper examines how various monetary policy signals such as repo rate changes, inflation reports, speeches, and minutes from monetary policy meetings affect the term structure of interest rates. We find that unexpected movements in the short end of the yield curve are mainly driven by unexpected changes in the repo rate. However, published inflation reports and speeches also have some impact on short rates. Speeches are found to be a more important determinant for the longer end of the term structure. Our conclusion is that central bank communication is an essential part of the conduct of monetary policy.     

Does the ECB act as a lender of last resort during the subprime lending crisis?: Evidence from monetary policy reaction models

We investigate whether the ECB aligns its monetary policy with financial crisis risk in EMU member countries. We find that since the outbreak of the subprime crisis the ECB has significantly increased net lending and reduced interest rates when banking and sovereign debt crisis risk in vulnerable EMU countries (Greece, Ireland, Italy, Portugal, and Spain) increases, while no significant effect is identified for the pre-crisis period and relatively tranquil EMU countries (Austria, Belgium, France, Germany, and the Netherlands). These findings suggest that the ECB acts as a Lender of Last Resort for vulnerable EMU countries.     

A Model for Studying the Effect of EMU on European Yield Curves

In January 1999, the European monetary union (EMU) was formally launched with 11 member countries. However, before May 1998 there was considerable uncertainty about who would join EMU, and whether the project would start on time. When a monetary union is formed, exchange rates between the member countries are irrevocably fixed, and yield spreads stemming from exchange-rate risk are eliminated. As a direct consequence, EMU affected the prices of long-term bonds well before 1999, but quantifying this effect can be difficult when there is uncertainty about the monetary union. We address these issues and develop a bond-pricing model which explicitly takes into account that a country may join a monetary union at a future, unspecified date. The empirical results show that a narrow EMU, consisting of Germany, France and the Benelux countries, has been priced with almost 100% probability throughout the period 1995–1998, whereas, on average, the implied probability of joining EMU has been somewhat lower for the other EU countries. However, in the period leading up to May 1998, the estimated probabilities have increased considerably for the countries that joined EMU in January 1999.     

Nonlinearities in the Brazilian Yield Curve

ABSTRACT

The article indicates the yield curve can be modeled using a continuous estimator as smooth transition regression, instead of traditional switch models, because bonds are traded continuously in the financial market. The results indicate that nonlinearity in the yield curve explains the pitfalls of monetary policy. The positive correlation between inflation and spread is consistent with a rise on uncertainty due to inflation risk or seems to indicate Brazilian Central Bank’s monetary policy credibility in the sample period. Therefore, if dependence on international capital exists, the Brazilian economic policy makers must monitor the movements in yield and analyze its feedback frequently in order to guide their plans and decisions.     

Monetary Policy Implementation: Making Better and More Consistent Use of the Federal Reserve's Balance Sheet

Since December 2015, the Federal Reserve has operated a new “floor system” in which it brings about desired changes in its targeted federal funds rate by managing the interest rate it pays on bank reserves and other short‐term liabilities. The design of this new system reflects the tendency of Fed officials to view monetary policy as affecting the economy through Keynesian” interest rate channels. From this Keynesian perspective, policy actions that change the size of the balance sheet are seen as tools for influencing credit market conditions that operate in addition to and independently of the Fed's monetary policy stance. The alternative monetarist framework proposed by the author views monetary policy and its effects as operating through the interaction between money supply and demand. Use of this framework makes clear that, even under a floor system, monetary policy actions designed to affect the aggregate price level and the rate of inflation must be accompanied sooner or later by traditional open market operations that have implications for the size and composition of the Fed's balance sheet. Use of the monetarist framework also underscores the likelihood that the Fed, by paying interest on reserves, has unknowingly contributed to the restrictiveness of its own monetary policies since the financial crisis, a period during which inflation has run consistently below target. More generally, the monetarist framework downplays the importance of the zero lower interest rate bound and suggests that monetary policy could be conducted more effectively by adopting and adhering to a consistent, rule‐like manner during good times and bad.     

Does the euro dominate Central and Eastern European money markets?

The so-called German Dominance Hypothesis (GDH) claimed that Bundesbank policies were transmitted into other European Monetary System (EMS) interest rates during the pre-euro era. We reformulate this hypothesis for the Central and Eastern European (CEE) countries that are on the verge of accessing the eurozone. We test this “Euro Dominance Hypothesis (EDH)” in a novel way using a global vector autoregressive (GVAR) approach that combines country-specific error correction models in a global system. We find that euro area monetary policies are transmitted into CEE money market rates, providing evidence for monetary integration between the eurozone and CEE countries. Our framework also allows for introducing global monetary shocks to provide at least tentative empirical evidence regarding the effects of the recent financial crisis on monetary integration in Europe.     

The great moderation of the term structure of UK interest rates

The conduct of monetary policy, the term structure of interest rates and the structure of the economy in the UK have changed over the post-WWII period. We model the interaction between the macroeconomy and financial markets using a time-varying VAR augmented with the factors from the yield curve. There is evidence of a great moderation in the dynamics of the yield curve, with the factors being persistent and volatile before the introduction of inflation targeting in 1992 but becoming stable afterwards. The introduction of time-variation in the Factor Augmented VAR improves the fit of the model and results in expectation hypothesis consistent yields that are close to actual yields, even at long maturities. Monetary policy shocks had a significant impact on the volatility of inflation, output and the policy rate over the pre-inflation targeting era, but their contribution has been negligible under the current regime. Shocks to the level of the yield curve accounted for a large fraction of inflation variability only before 1992.     

Measuring monetary policy and its impact on the bond market of an emerging economy

In view of multiple instruments used by many central banks in emerging market economies (EMEs), we derive a composite measure of monetary policy for India and assess its impact on the yield curve. Our results show that while monetary policy has the dominant impact among macroeconomic variables on the entire term structure, it is particularly strong at the shorter end and on credit spreads. Shifts in the level of the government yield curve and credit spreads also lead to changes in monetary policy. In terms of robustness, our measure performs better than a narrative-based measure of monetary policy available in the literature.     

Benchmark Bonds Interactions under Regime Shifts

In the present paper we examine the interactions among five benchmark ten year government bonds, namely those of the USA, Germany, France, Italy and the Netherlands. Our aim is to illustrate empirically a net of interactions existing among the major bond markets of Europe and the US market taking into account shifts in the underlying stochastic processes. For this purpose, differing from the rest of the relevant empirical literature, after specifying the long run equilibrium relations we estimate the linkages between the bond markets as subject to hidden Markov chains, by applying the Markov Switching Vector Error Correction framework (MS‐VECM). This formulation is found to efficiently reflect the shifts brought about by significant economic events, such as the European monetary unification. As a result we illustrate different short‐run relations referring to the periods before and after the monetary union. Overall, our empirical results indicate that stronger interactions among the markets of the system exist in the period after the EMU. Also, by means of a variance decomposition analysis we assess leader‐follower relations which indicate that the benchmark status of bonds has changed since the introduction of the common monetary policy framework in Europe.     

The interest rate effects of government bond purchases away from the lower bound

I analyze the recent experience of unconventional monetary policy in Sweden to study the interest rate transmission mechanisms of government bond purchases when interest rates are away from the lower bound. Using dynamic term structure models and event study regressions I find that government bond purchases have important portfolio balance and signaling effects. The signaling channel operates mainly by lowering short-rate expectations in the intermediate segment of the yield curve, while the portfolio balance channel is effective in lowering longer maturity term premia. In addition, I find that target interest rate policy and government bond purchases operate in different segments of the yield curve. This suggests that a combination of the two policies can be used to lower interest rates across the whole maturity spectrum, making monetary policy more expansionary.     

The changing relation between the Canadian and U.S. yield curves

The term structures of Canada and of the United States, two countries with historically interdependent economic ties, have been closely linked. We investigate the link between Canadian and U.S. yield curves and show previously strong correlations between yield curve components dissipate after Canadian monetary policy reforms in the early 1990s. We attribute the separated ties to the adoption of explicit inflation targets in 1991 and the maintenance of credibility in price stability as a central policy goal by the Bank of Canada. The effect is particularly evident in the diminished cross-country correlations of the short term bond yields. Additionally, there exists strong evidence of cointegration before the reforms, evidence which weakens after the policy change date. Lastly, the results on the term structure are shown using a vector autoregression with an endogenously determined break date for Canadian and U.S. estimates of the three-factor Nelson and Siegel (1987) yield curve model.
