(Un)Conventional monetary policy and bank risk-taking: A nonlinear relationship

This paper investigates the effect of monetary policy - especially unconventional monetary policy - on bank risk-taking behavior in Europe over the period 2000–2015. Using a dynamic panel model with a threshold effect, we estimate this effect on two measures of bank risk: the Distance to Default, which reflects the market perception of risk, and the asymmetric Z-score, which corresponds to an accounting-based measure of the risk. We find that loosening monetary policy (via low interest rates and increasing central banks' liquidity) has a harmful effect on banks’ risk, confirming the existence of the risk-taking channel. Moreover, we show that this relationship is nonlinear, i.e., with the sustainable implementation of unconventional monetary policies, the effects are stronger below a certain threshold.     

Bank-lending channel and non-financial firms: evidence for Spain

During the 1990s, liquidity was relatively abundant in the European Union and the European central banks mostly developed a relaxed monetary policy. While the bank lending channel view of the monetary policy would have suggested an increase in loans to firms in this context, the demand for bank corporate lending, however, slowed down, suggesting that monetary policy was not effective in this area. This article analyses how the financing behaviour of Spanish firms during 1992–2003 is related to their liquidity holdings and how this relationship may affect the effectiveness of the bank lending channel. The empirical evidence provided suggests that firms holding high liquid assets may replace bank lending by other sources of financing. Hence, higher liquidity holdings allow firms to invest in attractive investment projects in the event of a tightening of monetary conditions.      

Financing Channels and Monetary Policy in a Dual Banking System: Evidence from Islamic Banks in Indonesia

Using Indonesian Islamic banking data from 2003 to 2014, this article employs a panel regression methodology to investigate the responses of Islamic banks to changes in financing rates and monetary policy, which may differ depending on their characteristics. The results suggest that the financing rate has a negative impact on financing at Islamic banks, while bank‐specific characteristics have a positive influence on it. The size and amount of capital have a greater impact than liquidity on financing at Islamic banks. However, changes in monetary policy are insignificant on bank financing, which implies that the transmission of monetary policy through the Islamic segment of the banking sector is weak. Furthermore, the weak impact of monetary policy on bank financing can be explained by the dramatic expansion of Islamic banks during the sample period, which contributed to a substantial increase in deposit growth and a high liquidity position.     

Bank liquidity risk and monetary policy. Empirical evidence on the impact of Basel III liquidity standards

We extend the literature on the bank lending channel in two aspects. First, rather than following the literature by analyzing the impact of banks’ liquidity (measured via their asset portfolio) on monetary policy transmission, we study the role of banks’ actual liquidity risk, as measured by the Basel III liquidity regulations. Second, we investigate the effect of complying with the Basel III liquidity standards on monetary policy transmission. We use highly detailed bank-level data from Luxembourg for the period 2003q1--2010q4. Our findings are that monetary policy transmission works its way through small banks that also have a large maturity mismatch, as measured by the Net Stable Funding Ratio. In contrast, large banks with a small maturity mismatch increase their lending following a monetary policy shock, which confirms existing results that Luxembourg’s banks are liquidity providers to the European market. Based upon in-sample predictions and upon simulated data from an optimization model that takes the banks’ business models into account, we conclude that the bank lending channel will no longer be effective once banks adhere to the new Basel III liquidity regulations.     

Surplus liquidity,central bank losses and the use of reserve requirements in emerging markets

Since the turn of the millennium, stocks of foreign reserves held by central banks in many emerging markets and developing countries have exceeded currency in circulation. To steer money market rates, these central banks have been absorbing liquidity from, rather than providing it to, the banking sector in their regular monetary policy operations. When interest rates in countries with major reserve currencies are low, the yield on foreign reserves is low. A higher interest rate on liquidity‐absorbing operations may expose central banks to losses. Although a central bank is not a profit‐maximizing institution, central bank losses can undermine the independence of the central bank. Using data for a large panel of central banks, this paper provides some evidence that central banks tend to apply low‐remunerated reserve requirements when profitability is at stake.     

Monetary policy and bank lending in a low interest rate environment: Diminishing effectiveness?

This paper analyses the effectiveness of monetary policy on bank lending in a low interest rate environment. Based on a sample of 108 large international banks, our empirical analysis suggests that monetary policy is less effective in stimulating bank lending growth when interest rates reach a very low level. This result holds after controlling for business and financial cycle conditions and different bank-specific characteristics such as liquidity, capitalisation, funding costs, bank risk and income diversification. We find that the impact of low rates on the profitability of banks’ traditional intermediation activity helps explain the subdued evolution of lending in the period 2010–14.     

Monetary Policy Shocks and Heterogeneous Finance Decisions: A Model of Hidden Effort Choice and Financial Intermediation

Abstract. The paper investigates how monetary policy shocks influence the composition of firms' external finance given that firms are heterogeneous. Heterogeneity stems from differences in the availability of internal funds and in the monitoring costs associated with bank finance. These costs are determined by the intensity of the lending relationship. By using a delegated monitoring approach it is found that bank loans serve as a substitute for internal funds if the lending relationship is sufficiently close. Moreover, banks with strong credit ties to their customers are not only able to protect borrowers from liquidity constraints following a monetary tightening but are even able to extend their business lending.     

当前我国货币政策工具选择的依据及运用

2010年我国调整了实施两年多的宽松货币政策,宣布2011年实行稳健的货币政策。使货币政策从宽松转向稳健的最直接原因是目前我国物价上涨加快,资产泡沫化加剧,通胀预期上升。但是,紧缩货币政策工具的力度除了考虑国内物价因素以外,还应考虑到国际因素。当前,外围主要经济体增长率下滑、失业率高企,因而当前甚至今后一段时间内,央行在使用紧缩货币政策工具收紧流动性、防止资产泡沫风险时,应把握好节奏和力度,以防经济硬着陆风险。     

Inside the bank lending channel

This paper tests cross-sectional differences in the effectiveness of the bank lending channel. The results, derived from a comprehensive sample of Italian banks, suggest that heterogeneity in the monetary policy pass-through exists. After a monetary tightening the decrease in lending is lower for well-capitalized banks that are perceived as less risky by the market and are better able to raise uninsured deposits. Liquid banks can protect their loan portfolio against monetary tightening simply by drawing down cash and securities. The presence of internal capital markets in bank holding companies also contributes to insulate monetary shocks. Bank size is never relevant.     

Home sweet host: A cross‐country perspective on prudential and monetary policy spillovers through global banks

Prudential regulation of banks is multi‐layered: policy changes by home‐country authorities affect banks’ global operations across many jurisdictions; policy changes by host‐country authorities shape banks’ operations in the host jurisdiction regardless of the nationality of the parent bank. Do these policies create (unintended) cross‐border spillovers? Similarly, monetary policy actions by major central banks may also have effects on the behaviour of banks in other countries. This paper examines the effect that changes in home‐ and host‐country prudential measures have on cross‐border dollar credit provision, and how these interact with US monetary policy. We first run panel regressions with both layers of regulation, to examine which has a greater effect on cross‐border lending. We then use a novel approach to decompose growth in cross‐border bank lending into separate home, host and common components, and then match each with the corresponding home or host policies. Our results suggest that prudential policies can have spillover effects, which depend on the instrument used and on whether a bank's home or host country implemented them. Home policies tend to have larger spillovers on cross‐border US dollar lending than host policies. We also find that a tightening of US monetary policy can compound the spillovers of some prudential measures.     

金融危机、货币政策与信贷供给*——基于公司层面银行信贷数据的经验研究

不同的银行特征会对金融危机和货币政策传导的银行信贷渠道产生异质性影响。本文运用2001-2015年公司层面银行信贷数据实证检验了我国货币政策传导的银行信贷渠道,随后进一步研究金融危机对不同特征银行信贷供给的影响差异。经验研究发现：我国货币政策银行信贷渠道主要通过非国有控股银行传导,并引起不同资产负债表特征银行信贷供给的异质性反应。银行规模越大、流动性越强、资本充足率越高,银行信贷供给对货币政策越不敏感。金融危机期间,银行信贷渠道的传导效率显著降低,高资本充足水平的银行和国有控股银行受金融危机的冲击较小,并且宽松的货币政策对国有控股银行信贷供给调控的效率更高。     

The effect of US stress tests on monetary policy spillovers to emerging markets

This paper explores the transmission of US monetary policy through US banks to emerging market economies (EMEs) and the role that stress tests play in this transmission. Data on US banks’ monthly commercial and industrial loan originations shows that: (a) US bank lending to EMEs was sensitive to domestic monetary policy changes during the zero‐lower bound period. (b) Effects of monetary easing were heterogeneous across banks and depended on banks’ stress test results, a proxy for their capital strength. Only banks that comfortably passed the stress tests issued more loans to EME borrowers. (c) Effects of monetary tightening were more similar across banks. (d) Banks shifted their lending to safer borrowers within EMEs in response to monetary easing, leaving the risk of their overall loan books unchanged. These results support the hypothesis that bank capital affects the transmission of easier monetary policy, including across borders. We conjecture that bank lending to EMEs during the zero‐lower bound period would have been even higher had the United States not introduced stress tests for their banks.     

货币政策对金融生态的影响机理及实证检验——基于上市商业银行面板数据的分析

传统的货币理论忽视了货币政策对银行风险承担及金融生态的影响,文章从商业银行的微观视角出发研究了货币政策对金融生态的影响机理。理论层面,金融生态与货币政策制度供给、传导机制和有效性相互关联,货币政策则通过资产价格或估值机制、收入及现金流机制、追求收益机制、杠杆调整机制、道德风险机制和风险转移机制影响商业银行的风险承担;实证层面,构建了货币政策影响商业银行信贷投放和风险承担的数理模型,选取国有和股份制两类共12家上市商业银行2008-2013年的面板数据进行固定效应模型实证检验。结果表明,宽松货币政策导致商业银行的信贷投放规模增加、风险承担意愿增强,有利于优化金融生态,反之则反是;国有商业银行对货币政策变化更敏感,而股份制商业银行对金融生态更敏感。因此,在我国宏观经济管理中,需要货币政策与宏观审慎政策相互协调配合。     

What Do Data Say About Monetary Policy,Bank Liquidity and Bank Risk Taking?

This paper tests empirically the linkage between banks' investment and interbank lending decisions in response to interest rate changes. We draw conclusions for the monetary policy, which uses the interest rate as its main tool. Across European countries we find that the risk-free (i.e. monetary policy) interest rate negatively affects the liquidity retained by banks and the decision of a bank to be a lender in the interbank market. Instead, the interbank interest rate has a positive impact on these decisions. We also find that banks who lend show less risk-taking behaviour and tend to be smaller than those who are borrowers. Most importantly, the risk-free interest rate is positively correlated with loans investment and bank risk-taking behaviour.     

The credit squeeze during Russia's early transition: A bank-based view

This paper asks whether Russia's protracted inflation stabilization might have caused a credit squeeze and hence might have contributed to the output collapse in the first three years of the Russian transition. Russian monetary policy was not restrictive as a whole. Still, the occurrence of a credit crunch is not excluded, because of the Russian central bank's heavy reliance on required reserves to curb the inflationary effects of monetized budget deficits. Due to methodological limitations, we are forced to concentrate on a cross-sectional analysis of bank liquidity in 1994, in order to find possible indications about Russia's monetary stance from the point of view of the lending channel. We cannot reject that the huge excess reserves of Russian banks in 1994 were at least partially due to excess liquidity. This suggests that there is no direct relation between the monetary policy of high required reserves and the observed credit crunch. The question of why banks preferred to hold excess liquidity deserves further attention. This question is still relevant, because Russian commercial banks have again accumulated excess reserves in 1999, in the aftermath of the banking crisis, triggered by the August-1998 crisis.     

央行票据调控可持续性分析

央行票据是中央银行为调节商业银行超额准备金而向商业银行发行的短期债务凭证,是中央银行为调节商业银行流动性而出台的一项货币政策工具,其实质是中央银行债券。目前,央票已经是债券市场不可或缺的短期投资工具和流动性管理工具。但伴随中国经济增长趋势的放缓,央行票据发行规模的下降,央票是否继续存在的争论也由此而起。通过分析我国央行票据的发展情况及现状,对央票调控的利弊进行分析,并为央票存在的持续性寻求合理的理论支持。     

The Credit Channel at Work: Lessons from the Financial Crisis in Korea

We demonstrate that the credit channel of transmission of monetary/financial shocks appears to have aggravated Korea's economic crisis. We use micro-data gathered at the individual bank level to identify this channel of transmission. Our major findings are as follows: i) consistent with banks' autonomous retrenchment in loan supply, monetary tightening broadens the spread between marginal bank lending rates and corporate commercial paper rates; ii) credit limits on overdrafts – arguably a proxy identifying shifts in loan supply – react negatively to the monetary squeeze; iii) large negative capital shocks induce banks to disproportionately slow-down both lending and deposit taking and to disproportionately raise their lending rates. Our findings lend unequivocal support to the hypothesis that banks' autonomous contraction restricted the availability of credit and magnified the increase in its cost. In turn, this compounded the Korean crisis by aggravating liquidity constraints for the vast majority of agents who rely only on bank credit as an external source of funds.     

INTERNATIONAL CREDIT CHANNEL OF MONETARY POLICY: AN EMPIRICAL NOTE

A longstanding macroeconomic issue is how monetary policy affects the real economy. There are economists placing an emphasis on the role of bank lending in monetary transmission. Their view, called the credit view, is that a monetary tightening shifts the supply schedule of bank loans left, thereby forcing bank‐dependent borrowers to cut back on expenditures. In the literature, the credit view is typically studied in a closed‐economy context. In reality, however, banks make international loans through their overseas branches and subsidiaries. This suggests that the credit view should be studied in an open‐economy context. This paper proposes the international credit view: a monetary‐policy shock originated in one country propagates to another through banks’ reallocation of funds between the two countries. For testing the hypothesis, Australia and New Zealand provide an excellent case to study. This is because Australian‐owned banks dominate the banking market in New Zealand. This paper aims to test the international credit view within a framework of vector auto‐regression models. A significant and robust finding is that the supply schedule of loans shifts left in New Zealand after a monetary tightening in Australia.     

货币政策能否促进银行对小微企业信贷投放——基于宏观经济不确定视角的研究

本文研究在宏观经济不确定条件下,不同货币政策工具能否促进银行对小微企业信贷投放。首先,将货币政策引入考虑了宏观经济不确定性的银行资产组合模型中,论证货币政策、宏观经济不确定性与银行信贷资产配置的理论关系。然后利用我国181家银行2004—2018年的数据,检验在宏观经济不确定条件下,不同货币政策工具对银行小微企业信贷行为调控的作用效果。研究结果表明：宏观经济不确定性会抑制银行信贷行为。其中小微企业信贷占比较大的银行受到的影响更为显著。与数量型货币政策相比,价格型货币政策能够更显著地减轻不确定性对银行小微信贷的消极影响。其中银行同业拆借利率的调控效果最强。研究结论对于选择适宜的货币政策工具促进银行向小微企业信贷投放,化解经济不确定性对银行信贷行为的影响并助力小微企业发展等具有政策借鉴意义。     

BANK EFFICIENCY AND THE EFFECTIVENESS OF MONETARY POLICY

Advances in information technology and bank consolidation have altered the way banks operate by necessitating that banks control costs and provide services efficiently to remain competitive. Given the unique role bank operations play in the transmission of monetary policy, a key unresolved question is whether bank efficiency alters monetary policy outcomes. Using a stochastic frontier approach to measure cost‐efficiency and panel data of U.S. bank balance sheets, we show that banks with greater cost‐efficiency are more sensitive to monetary shocks.
