Quantitative easing tilts the balance between monetary and macroprudential policy

Quantitative easing by central banks has stimulated risk-taking in financial markets and contributed to a liquidity-driven boom in asset prices. It puts the relation between monetary policy and financial stability into a new perspective. We show by a regression analysis for a panel of 11 advanced economies that an asset price bust has adverse effects on inflation. The effect of stock prices and corporate bond rates on inflation is significant, also if we control for developments in credit. This insight implies that in conducting and implementing quantitative easing, central banks should closely monitor and take into account asset bubbles.     

THE EFFECTS OF THE BANK OF JAPAN'S ZERO INTEREST RATE COMMITMENT AND QUANTITATIVE MONETARY EASING ON THE YIELD CURVE: A MACRO‐FINANCE APPROACH*

This paper empirically investigates the effects of the Bank of Japan's (BOJ) zero interest rate commitment and quantitative monetary easing on the yield curve. Applying a macro‐finance approach, we decompose interest rates into expectations and risk premium components and extract the market's perception of the BOJ's policy stance. We make clear the counterfactual policy without the BOJ's commitment. We find some evidence that the commitment lowered interest rates and mat raising the reserve target may have been perceived as a signal indicating the BOJ's accommodative policy stance. The portfolio rebalancing effect has not been found to be significant.     

Which Vested Interests Do Central Banks Really Serve? Understanding Central Bank Policy Since the Global Financial Crisis

Inspired by Thorstein Veblen’s ideas, I analyze the behavior of central banks from the perspective of how institutions are captured by vested interests. Since the global financial crisis in 2008, there has been a shift in the conduct of monetary policy. Much like the behavior of asset holders themselves, who, in times of crisis, sought to trade off lower returns with more stable asset values, monetary policy changed from a de facto policy of stabilizing rentier income to one of preserving asset prices or rentier wealth. I analyze this particularly through the lenses of what happened with quantitative easing (QE) in the US, which coincided with a collapse of real interest rates, while asset prices were stabilized. This can also be seen in the way the banking sector was supported by QE where the market for mortgage-backed securities was sustained even as it actually meant a lower profitability for the overall U.S. banking sector during the QE interventions.     

Are monetary policy shocks causal to bank health? Evidence from the euro area

Despite considerable efforts of the European Central Bank (ECB) to support bank intermediation after the 2008 financial crisis, the recovery of euro area banks remained incomplete. Although many studies indicate that central banks can influence the stock prices of firms through their policy actions and communication, a knowledge gap exists as to whether the ECB's monetary policy can influence bank health. Through a high-frequency identification approach, this study reveals that the causal effect of conventional monetary policy action and communication by the ECB on bank stock prices differed over time, whereas its influence on bank financing costs was robust. This study provides new evidence showing that information effects related to policy easing surprises in the aftermath of the 2008 financial crisis hampered the ECB efforts to improve bank health and that its Odyssean communication signals (related to forward-looking announcements of policy easing) supported bank health during this phase. Local projections suggest that the response of banks to monetary policy shocks displayed some persistence, where ECB policy surprises and communications that shifted up (down) the yield curve were normally positive (negative) for bank health. The findings solicit a new perspective when assessing the influence of the ECB's monetary policy measures on euro area banks.     

IDEAL AND REAL JAPANESE MONETARY POLICY: A COMPARATIVE ANALYSIS OF ACTUAL AND OPTIMAL POLICY MEASURES*

This paper discusses the successes and failures of Japanese monetary policy by evaluating policies from January 1980 to May 2003 in the light of optimal policy rules. First, we quantitatively conceptualize the Bank of Japan (BOJ)'s policy decisions by employing Bernanke and Mihov's (1998 ) econometric methodology for developing monetary policy measures and term the resulting policy measure the ‘actual policy measure’. Next, assuming that the BOJ is committed to optimal policy rules, we simulate optimal policy paths, which we term ‘optimal policy measures’. We evaluate Japanese monetary policy historically by comparing actual and optimal policy measures.     

Response of Asset Prices to Monetary Policy under Abenomics

In this paper, I investigate the causes of the recent sharp response of the yen and Japanese stock prices to the discussion of, and the subsequent implementation of bold monetary easing by the Bank of Japan as demanded by Prime Minister Abe. I present statistical evidence that the response of the two asset prices have indeed been unusually large relative to the past experience with nonconventional monetary policy (NCM) even after allowance is given for the rise in global economic activity and asset prices. I also point out that the rally has been led by speculative trading by foreign investors, while domestic investors have largely stayed on the sidelines. I discuss possible reasons for such foreign investor behavior. Simply put, the unprecedented political pressure raised hopes of the adoption of bold measures by the Bank of Japan. I discuss, however, the possibility that the room for further action by the Bank is quite limited apart from what might be called a targeted helicopter drop of money. I also point out the possibility that investor behavior may have not been based on economic fundamentals. The asset price volatility since April 2013 is interpreted in the light of such discussions.     

Collateral rehypothecation,safe asset scarcity,and unconventional monetary policy

We build a mark-to-market model where commercial banks can enlarge their balance sheets, repledging the available collateral several times to exchange liquidity through the interbank market. In bad times, the fall of risky asset price disrupts the length of the repledging chain due to the increase of the haircut and the decrease of external assets' value. In such a scenario, the central bank can intervene implementing unconventional monetary policies by purchasing a fraction of the banking system's external assets, both safe treasury bonds, and risky asset-backed securities, to inject liquidity. Our results show that a quantitative easing policy that purchases only safe assets is highly ineffective in restoring the intermediation activity to the pre-crisis level due to its inability to sustain the risky asset price and the repledging chain of collateral. Instead, focusing on risky assets only, the monetary authority can sustain risky asset prices, avoiding the freezing of the money market.     

Monetary policies to counter the zero interest rate: an overview of research

Many central banks have lowered their interest rates close to zero in response to the crisis since 2008. In standard monetary models the zero lower bound (ZLB) constraint implies the existence of a second steady state in addition to the inflation-targeting steady state. Large scale asset purchases (APP) have been used as a tool for easing of monetary policy in the ZLB regime. I provide a theoretical discussion of these issues using a stylized general equilibrium model in a global nonlinear setting. I also review briefly the empirical literature about effects of APP’s.

Effects of mineral-commodity price shocks on monetary policy in developed countries

This article investigates effects of changes in mineral commodity prices on monetary policy. Using macroeconomic data from three mineral-producing countries (Australia, Canada and New Zealand) and two non-mineral-resource countries (USA and UK), I estimate the impulse response functions of the policy interest rates and the core consumer price index (CPI) inflation rates to mineral-commodity price shocks. I find that the central banks in both groups of the examined countries significantly respond to mineral-commodity price shocks. In responses to an unexpected 10% increase in mineral commodity prices, the central banks are estimated to increase their policy interest rates by approximately 0.8 percentage points. Moreover, the central banks seem to take anticipatory policy reactions to control core CPI variations triggered by these shocks. Thus, mineral commodity prices would act as important determinants of the monetary policies in both groups of the examined countries. These findings would be useful for analysing Taylor rules in their countries. However, effects of the increase in their policy interest rates on core CPI inflation cannot be identified for the examined countries.

资产价格泡沫与货币政策应对——事先行动还是事后反应

资产价格泡沫的产生原因是多方面的,早期的研究更多地认为资产泡沫来自于投资者的非理性因素,但是随着金融自由化进程的推进,与经济金融发展水平不相适应的金融自由化也成为资产泡沫产生的一个重要原因。而对于资产价格泡沫的货币政策应对一直存在争议,一些学者主张货币政策应该忽略资产价格,而另一些学者则主张货币政策应该对资产价格作出反应。本文基于后一种观点,来探讨当预期资产价格将出现泡沫时,货币政策是该事先行动还是事后反应,为此,本文引入产出跨期配置的理论,来阐述货币政策应对资产价格泡沫的决策模型。

Re-exploring the nexus between monetary policy and banks' risk-taking

In this paper, we analyse the link between monetary policy and banks' risk-taking behaviour. Some theoretical and empirical studies show that monetary easing increases banks' appetite for risk related to asset valuation and the search for higher yield. However, the low interest rate environment that began in 2010 is casting doubt on these findings. Our study adds to analyses of the monetary risk-taking channel considering non-linearity, especially testing threshold effects in this channel. Using a dataset of US banks, we find that the impact of low interest rates on banks' risk behaviour depends on the previous monetary regime, that is on the deviation of monetary rates from the Taylor rule. We complement the literature on the Taylor rule and provide arguments that extend the use of the Taylor rule by Central Banks to financial stability purposes.     

Financial stress,economic activity and monetary policy in the ASEAN-5 economies

This article uses a structural vector autoregression approach to analyse the impact of financial stress on the economy and the relationship between monetary policy and financial stress in the ASEAN-5 economies (Indonesia, Malaysia, Philippines, Singapore and Thailand). We find that an increase in financial stress leads to tighter credit conditions and lower economic activity in all five countries. The estimated impact on the real economy displays an initial rapid decline followed by a gradual dissipation. In Malaysia, the Philippines and Thailand, the central banks tend to reduce policy interest rates (IRs) when financial stress increases, although there is substantial cross-country variation in the magnitude and time dynamics. The lower policy IRs are found to have little significant effects in lowering financial stress, but are still effective in stimulating economic activity through other channels. These findings imply that easing monetary policy is likely necessary but insufficient to address growth slowdowns associated with financial stress. Monetary easing should instead be complemented with other policy measures which are targeted at restoring financial stress to normal levels.     

Risk-taking channel,bank lending channel and the “paradox of credibility”: Evidence from Brazil

If from one hand credibility is important for the conduct of monetary policy, on the other hand, greater credibility may eventually stimulate the creation of bubbles in the credit market and asset prices through the risk-taking channel, and as a consequence, bring to reality the “paradox of credibility”. The “paradox of credibility” is the new dilemma posed to central banking in the effort to conciliate monetary policy and banking regulation under inflation targeting regimes. Thus, the present work aims to: (i) analyze the impact of central bank actions and the macroeconomic environment on the risk perception of banks, and; (ii) analyze the influence of this risk perception of banks on the credit spread, considering both the credit channel and the risk-taking channel. Based on an econometric analysis, the work provides evidence about: (i) the “paradox of credibility” and the risk-taking channel; (ii) the influence of monetary policies on the risk perception of banks and, as a consequence, on the credit spread; (iii) the procyclical nature of banks in relation to economic activity, and; (iv) the adherence of the countercyclical indicator (called credit gap) proposed in Basel III for the Brazilian case.     

Macroeconomic Effects of Asset‐Price Shocks in a Globalized Financial Market

In this paper, I study a model in which shocks to asset prices affect the real sector of the economy through a credit channel. As financial markets become internationally integrated, the economy becomes less vulnerable to domestic asset‐price shocks, but more vulnerable to foreign asset‐price shocks. To the extent that monetary policy stabilization is feasible and desirable, the globalization of financial markets shifts the focus of monetary policy from domestic asset prices to worldwide asset prices.     

A two-pillar DSGE monetary policy model for the euro area

The current financial crisis has revived the interest for monitoring both monetary and credit developments. Over the past two decades, consistent with the adoption of inflation targeting strategies by a growing number of central banks and the development of New Keynesian models for which monetary aggregates are largely irrelevant, money and credit have been progressively neglected in the conduct of monetary policy. A striking exception has been the Eurosystem, which has implemented a strategy known as the “two-pillar monetary policy strategy” giving a prominent role for money. In this paper, we develop a small optimizing model based on Ireland (2004), estimated on euro area data and featuring this two-pillar strategy. We evaluate an ECB-style cross-checking policy rule in a DSGE model with real balance effects of money. We find some evidence that indeed money plays a non-trivial role in explaining the euro area business cycle. This provides a rationale for the central bank to factor in monetary developments but also raises some issues regarding the reliability of M3 as an appropriate monetary indicator. We find some evidence that the ECB has systematically reacted to a filtered measure of money growth but weak evidence it has reacted more aggressively during excess money growth periods.     

Impact of asset price fluctuation on China’s monetary policy: An empirical analysis based on quarterly data, 1994–2006

The strenuous fluctuation in global asset price in recent years has had a profound impact on the economic and social development of every country. An empirical analysis indicates that asset prices (the stock price index and real estate prices) are important endogenous variables affecting the interest rate reaction function of central bank monetary policy. With expected inflation as a given, each one percentage point rise in output gap will cause a 0.79 percentage point reduction in interest rates by the central bank and each one percentage point rise in real estate price will result in a 2.2 percentage point rise in interest rates. The stock price index does have an influence on the trends in monetary policy, but it is less salient than the impact of housing prices. We also show that monetary policy that employs asset price as an endogenous variable increases the central bank’s control in seeking to attain its objectives. Therefore we suggest that the central bank should make asset price fluctuation an endogenous variable and incorporate it into its forward-looking interest rate rule, in order to facilitate the healthy development of China’s markets for real estate, stocks and derivatives, energy and bulk commodities and maintain rapid, smooth, sustainable and harmonious economic development.     

Stock Market Responses Under Quantitative Easing: State Dependence and Transparency in Monetary Policy

This paper evaluates the effects of unconventional monetary policies adopted by the Bank of Japan from the year 2001 to 2006. A new measure is proposed to identify a nontraditional monetary policy shock from policy packages under the zero lower bound of short‐term nominal interest rates during the quantitative easing period, using data on intraday 3‐month Euroyen futures rates. We find that stock markets do not react to a policy surprise in an expected manner and negatively respond to a monetary easing surprise. Moreover, we find an asymmetric response during a boom and a recession and a nonlinear reaction because of increasing uncertainty concerning future inflation dynamics and the enhancement of monetary policy transparency. Our result suggests that it is difficult to implement unconventional monetary policy to manage agents’ expectations and a ‘lean against the wind’ policy to prevent asset bubbles, particularly at the zero bound.
