Monetary policy and macroprudential policy: Rivals or teammates?

This paper sheds some light on situations in which monetary and macroprudential policies may interact (and potentially get into conflict) and contributes to the discussion about the coordination of those policies. Using data for the Czech Republic and five euro area countries we show that monetary tightening has a negative impact on the credit-to-GDP ratio and the non-risk-weighted bank capital ratio (i.e. a positive impact on bank leverage), while these effects have strengthened considerably since mid-2011. This supports the view that accommodative monetary policy contributes to a build-up of financial vulnerabilities, i.e. it boosts the credit cycle. On the other hand, the effect of the higher bank capital ratio is associated with some degree of uncertainty. For these and other reasons, coordination of the two policies is necessary to avoid an undesirable policy mix preventing effective achievement of the main objectives in the two policy areas.     

Pursuing financial stability under an inflation-targeting regime

We evaluate two main views on pursuing financial stability within a flexible inflation-targeting regime. It appears that potential gains from an activist or precautionary approach to promoting financial stability are highly shock dependent. We find support for the conventional view that concern for financial stability generally warrants a longer target horizon for inflation. The preferred target horizon depends on the financial stability indicator and the shock. An extension of the target horizon favoring financial stability may contribute to relatively higher variation in inflation and output.      

Can non-interest rate policies stabilize housing markets? Evidence from a panel of 57 economies

This paper investigates the effectiveness of nine non-interest rate policies on house prices and housing credit using data from 57 economies and periods of up to three decades. We find that introductions or reductions in the maximum debt-service-to-income ratio, and increases in housing-related taxes, have significant negative effects on housing credit, with a typical tightening action lowering the real credit growth rate by 4–6 percentage points and by 3–4 percentage points, respectively, over the subsequent four quarters. Increases in housing-related taxes moderate house price growth, with a typical increase slowing real house price appreciation by 3–4 percentage points over the same horizon.     

Monetary and financial stability in the euro area: Pro-cyclicality versus trade-off

This paper investigates the nexus between monetary stability and financial stability. We examine, in the experience of EMU between 1994 and 2008, first, the response of the term structure of interest rates, share prices, exchange rates, property price inflation and the deposit–loan ratio of the banking sector (our proxies for financial stability) to changes in the consumer price level and ECB policy rate (our proxies for monetary stability); second, whether and to what extent lower inflation has caused share price stability and how ECB policy rate has reacted to inflation. Using a sign-restriction-based VAR approach, we find that there is a pro-cyclical relationship between monetary and financial stability in the long-run. With a positive inflation shock, we find on average a 2% estimated decline in share prices. This suggests that the interest rate instrument used for inflation targeting is conducive to financial stability.

Benchmarking macroprudential policies: An initial assessment

In recognition of the severe consequences of the recent international financial crisis, the topic of macroprudential policy has elicited considerable research effort. The present study constructs, for 46 economies around the globe, an index of the capacity to deploy macroprudential policies. Building on elements that have been the subject of recent research, we develop an index that aims to represent the essence of what constitutes a macroprudential regime. Specifically, the index quantifies: (1) how existing macroprudential frameworks are organized; and (2) how far a particular jurisdiction is from reaching the goals established by the Group of Twenty (G20) and the Financial Stability Board (FSB). The latter is a benchmark that has not been considered in the burgeoning literature that seeks to quantify the role of macroprudential policies.     

Monetary policy and financial (in)stability: An integrated micro–macro approach

Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.     

Inflation targeting: Is IT to blame for banking system instability?

In light of the financial crisis, the practice of inflation targeting (IT) has been blamed for authorities’ failure to respond to the increase in financial systemic risk and to the development of asset bubbles. However, utilizing a rich database containing nearly 5500 commercial banks from 70 countries (among which, 22 are IT) for the period 1998–2012, this paper argues that on average, inflation targeting national banking systems (i) are more stable; (ii) possess sounder systemically important banks; and (iii) are less distressed than (or at least as distressed as) other banks during periods of global liquidity shortages. Our results are robust to a series of tests, such as when we compare countries with the same legal origins or control for the delegation of bank supervision responsibility to bodies other than the central bank. Overall, we conclude that IT cannot be blamed for contributing to financial fragility.     

房价波动、金融稳定与最优宏观审慎政策

本文通过构建包含家庭住房抵押借款摩擦和银行贷款摩擦的动态随机一般均衡模型,重点考察了异质性冲击下房价波动对金融稳定的影响。研究发现,房价上涨会导致银行风险溢价及杠杆率显著上升,进而加剧金融体系的内在不稳定。为降低房价波动及维护金融稳定,选取两类宏观审慎政策工具进行逆周期调控实验,结果表明,在住房需求冲击下,金融管理部门应选取贷款价值比政策,且应对房贷积极调控,而对房价进行中性调控。在最终产品部门生产率冲击、房地产部门生产率冲击及跨期偏好冲击下,应选取资本充足率政策,但对房贷和房价调控力度的把握则存在差异。本研究为厘清房价波动对金融稳定的动态传导机制,以及金融管理部门如何选取宏观审慎政策工具以稳定房价并降低系统性金融风险提供了启示。     

货币政策传导过程中的金融体系研究

金融体系在货币政策传导过程中起“中介”作用,货币渠道过程是通过金融市场从货币政策冲击到市场零售利率的价格传导过程,信贷渠道是通过商业银行从中央银行到商业银行的数量传导过程。完善我国金融体系有利于提高货币政策传导效果,同时也是市场经济体制改革的要求,我国中央银行实施货币政策时应该考虑区域金融差异的客观事实。

Monetary Policy and Financial Markets

Monetary policy and financial markets are intrinsically linked. Central banks conduct monetary policy by influencing financial market prices. Financial market prices reflect the expectations of market participants about future economic and monetary developments. Monetary policy works primarily through expectations. Transparency and credibility render monetary policy more effective. However, they are no substitutes for action. If a credible central bank uses words with the explicit aim of substituting them for action, it will risk losing credibility. To avoid what has been described as “the dog chasing its tail” problem, central banks must exercise caution in basing their monetary policy decisions on financial market information. The information about expected future developments reflected in market prices must be continuously cross-checked against economic and monetary indicators in what amounts to a “checks and balances” approach to monetary policy.     

宏观审慎监管：一个文献综述

金融危机的爆发,使人们对金融监管更加重视。在后危机时代,诸如金融监管如何克服金融体系的顺周期性,如何防范和降低金融体系的系统性风险,如何从监管的角度保障金融和经济的稳定等等问题需要监管当局的重新审视。而以金融稳定为目标的宏观审慎监管,作为后危机时代金融监管发展的新方向,成为国内外学者的研究热点。因此,对宏观审慎监管的文献梳理便显得十分重要,并且能够为其今后在中国的进一步发展提供更加丰富的理论依据。
