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 role of banks in the Czech monetary policy transmission mechanism

With this work, I aim to enrich the knowledge about the monetary policy transmission mechanism in the Czech Republic with empirical evidence on the impact of monetary policy on bank lending. Using a panel of quarterly time series for Czech commercial banks for the period 1996–2001, I study the overall effect of monetary policy changes on the growth rate of loans and the characteristics of the supply of loans. The characterization of the credit market's supply side allows us to make inferences on the operativeness of the credit channel (the bank lending channel and the broad credit channel) of the monetary transmission mechanism. I find that changes in monetary policy alter the growth rate of loans, with considerably stronger magnitude in the period 1999–2001 than in the period 1996–1998. From the analysis intended to capture the characteristics of the supply of loans, I conclude that the lending channel was operative in the period 1996–1998: I find cross‐sectional differences in the lending reactions to monetary policy shocks due to the degree of capitalization and to liquidity. For the subsequent period 1999–2001, the results also show distributional effects of monetary policy due to bank size and its bank's proportion of classified loans. In the context of steadily decreasing interest rates, this can bolster the supposition of financial frictions between borrowers and lenders and hence, that of an operative broad credit channel.     

The Effectiveness of Unconventional Monetary Policy in Japan

Since the global financial crisis of 2007–2008, central bankers around the world have been forced to abandon conventional monetary policy tools in favor of unconventional policies such as quantitative easing, forward guidance, and even lowering the interest rate paid on bank reserves into negative territory. Japan, which faced a crisis in its banking sector and came up against the theoretical zero lower bound on interest rates nearly a decade earlier, was a pioneer in the use of many of these unconventional policy tools. This article analyzes the effectiveness of Japan’s bold experiment with unconventional monetary policy. Using a panel of bi-annual bank data covering the full universe of Japanese commercial banks over a fifteen-year period, this study analyzes the effectiveness of quantitative easing policy on the bank lending channel of monetary policy transmission. Our findings suggest that Japan’s unconventional monetary policy worked: there is a bank lending channel of monetary policy transmission in Japan. These results are robust to the inclusion of time fixed effects and generalized method of moments analysis.     

How important is the credit channel in the transmission of monetary policy in Mexico?

This article empirically examines the importance of the credit channel of monetary policy in Mexico for the period 2004–2013. We estimate a vector autoregressive (VAR) model to analyse the effects of a monetary policy shock on real output, and we also use a threshold VAR model to investigate asymmetric effects of contractionary and expansionary policies. The empirical results suggest that a contractionary monetary policy results in a fall in the supply of loans together with an increase in the spread between the lending and deposit rate. To the extent that some borrowers are dependent on bank loans for credit, the reduced supply of loans amplifies the effects of monetary policy on output associated with the traditional interest rate channel. Our results also suggest that the importance of the credit channel is larger for contractionary shocks than for expansionary shocks.     

The Bank Lending Channel and Monetary Policy Rules: Evidence from European Banks

There exist two main channels of the monetary transmission mechanism: the interest rate and the bank lending channel. This paper focuses on the latter, which is based on the central bank’s actions that affect loan supply and real spending. The supply of loans depends on the monetary policy indicator, which, in most studies, is the real short-term interest rate. The question investigated in this paper is how the operation of the bank lending channel changes when this short-term indicator is allowed to be endogenously determined by the target rate the central bank sets through a monetary rule. We examine the effect that a rule has on the bank lending channel in European banking institutions spanning the period 1999–2009. The expectations concerning inflation and output affect the decision of the central bank for the target rate, which, in turn, affect private sector’s expectations —commercial banks— by altering their loan supply.     

Reserve requirements and the bank lending channel in China

This paper examines how reserve requirements influence the transmission of monetary policy through the bank lending channel in China while also taking into account the role of bank ownership. The implementation of Chinese monetary policy is characterized by the reliance on the reserve requirements as a regular policy tool with frequent adjustments. Using a large dataset of 170 Chinese banks for the period 2004–2013, we analyze the reaction of loan supply to changes in reserve requirements. We find no evidence of the bank lending channel through the use of reserve requirements. We observe, nonetheless, that changes in reserve requirements influence loan growth of banks. The same findings hold true for other monetary policy instruments. Further, we show that the bank ownership format influences transmission of monetary policy.     

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.     

The transmission of bank capital requirements and monetary policy to bank lending in Germany

We investigate the transmission of changes in bank capital requirements and monetary policy, and their interaction, on German banks’ corporate loan growth and lending rates. Our results show that increases in capital requirements are associated with an immediate decrease in total domestic and cross‐border bank lending. Changes in the euro area's monetary policy stance are positively related to corporate loan interest rates in general. Regarding the interacting effect of national bank capital requirements and euro area monetary policy, we observe that the transmission of accommodative euro area monetary policy to corporate lending rates can be attenuated by contemporaneous increases in bank capital requirements. Moreover, more strongly capitalized banks increase their loan growth in response to accommodative monetary policy whereas, for weaker banks, increasing capital requirements implies a decrease in their corporate loan growth. Our results confirm a tradeoff between higher capital requirements and accommodating monetary policy originating from banks’ capital constraints.     

The Role of Banks in Monetary Policy Transmission: Empirical Evidence from Russia

This paper focuses on the role of the banking sector in monetary policy transmission in an emerging economy with a rapidly developing financial system. Specifically, we examine whether the central bank's monetary policy stance affects banks' lending behavior. Based on a comprehensive quarterly dataset on all Russian banks from 1Q1999 to 1Q2007, we find evidence for the existence of a bank lending channel in Russia. Contrary to several studies on developed economies, the level of a bank's capitalization matters for the transmission process. Better capitalized banks are less likely to adjust their lending practices following a change in the monetary policy stance.     

The bank lending channel of monetary policy in EU countries during the global financial crisis

The study examines the existence of the bank lending channel of monetary policy in European Union (EU) countries. The paper advances current research on the monetary transmission mechanism in the following ways: Firstly, we analyze the differences between ‘old’ Economic Monetary Union (EMU) and ‘new’ EU countries. Secondly, we examine the key bank characteristics and monetary policy indicators that may have an impact on the bank lending channel. We assume that short-term market interest rates and monetary aggregate M2 affect banks' activities. We apply the generalized method of moments (GMM) with pooled data from 1999 to 2012. We show that in the pre-crisis period the effect of changing the short-term market interest rates on the bank lending channel of monetary policy is more pronounced among ‘old’ EMU countries, whereas the effect of M2 is significant during the period of the global financial crisis (GFC) among ‘old’ EMU countries. Last but not least the important finding is that banks in ‘new’ EU countries react differently to monetary shocks.     

利率市场化视角下的货币政策风险承担渠道问题研究*

利率市场化进程的深入可能会对我国货币政策传导、金融稳定等产生不可忽视的影响。基于此,本文研究了利率市场化对货币政策风险承担渠道的影响。结果表明：（1）我国存在货币政策风险承担渠道,且从利率市场化间接度量的维度来看,在考虑以直接效应来衡量的贷款利率市场化之后,银行的实际风险承担水平上升;但是在考虑以价格约束效应来衡量的存款利率市场化之后,其效果并不明显。（2）从利率市场化直接度量的方法来看,直接引入虚拟变量的研究发现贷款利率市场化会使得货币政策对银行风险承担水平的影响变得明显;进一步从利率市场化综合度量的维度,引入整体的利率市场化指数的方法则发现,随着利率市场化进程的深入,银行的实际风险承担水平会上升。（3）利率市场化对货币政策风险承担渠道的影响在不同类型银行间存在差异。     

Political incentives and the effectiveness of monetary policy: evidence from China’s city commercial banks

From the perspective of official-and-director (OAD), this article takes studies of the effect of monetary policy on bank loans to the heterogeneity of bank. We explore how political incentives affect the lending channel of monetary policy transmission, using a sample of China’s city commercial banks during 2006–2014. And we further analyse the role of OAD’s characteristics, including administrative rank and age. The results indicate that although tight monetary policy can reduce bank loans, the OAD can weaken this relationship, and the higher is the administrative rank of OAD, the larger is the effect. And the older is OAD, the larger is the effect. More importantly, the relationship between monetary policy and bank loan is insignificant in banks with OAD, implying that the lending channel of monetary policy is absent when considering the role of OAD.     

Bank Behaviour and the Channel of Monetary Policy in Japan, 1965–1999

Using monthly data, this paper investigates whether there are differential effects of monetary policy across bank size and business size in Japan, to test the presence of the "bank lending channel" of monetary policy. It also considers that channel for the aggregate of banks. Prior to the end of 1984, support is found for the bank lending channel and also partly for the money channel. The study of the period from 1985 onwards suggests that no channel of monetary policy has been substantially effective in Japan.     

The link between the federal funds rate and banking system distress: An empirical investigation

We investigate the association between deviations of the monetary policy rate from its benchmark, and systemic risk between 2001 and 2017. We adopt an impulse response function framework that uses the local projections method model proposed by Jorda (2005). We find that paying interest on reserves by the Fed beginning in 2008 introduced a monetary policy regime shift between the period that the Fed did not pay interest on reserves and the period that it did. Consequently, while we identify a positive and significant link between deviations of the policy rate from its benchmark and systemic risk in the former period, this link was broken in the latter period. During the former period, upsurges in the fed funds rate raised bank costs and increased bank distress. In contrast, during the latter period, interest payment on reserves exceeded the policy rate, except for 2009Q1, and as a result, banks did not expand lending in response to the Fed's reserve injections, instead, holding large amounts of excess reserves. This practice produced greater bank profitability and reduced bank liquidity risk and credit risk, without increasing systemic risk.     

Financial systems and the cost channel transmission of monetary policy shocks

We study the role of financial systems for the cost channel transmission of monetary policy in a calibrated business cycle model. We characterize financial systems by the share of bank-dependent firms and by the degree of the pass-through from policy to bank lending rates, for which we provide empirical estimates for the euro area and the US. For plausible calibrations of the dynamics of the lending rate we find that the cost effects directly related to interest rate movements have only a limited effect on the transmission mechanism.     

基于SVAR模型的货币政策传导效果研究

利用2004年1月至2011年3月中国大陆31个省(自治区、直辖市)的月度数据,建立结构向量自回归模型,利用脉冲响应函数,对我国货币政策的省际传导渠道和传导效果进行实证研究。结果表明:我国货币政策的传导效果——无论从政策工具到中介目标,还是从中介目标到实体经济,都存在明显的省际差异。依据实证结果,从稳物价、促增长和缩小地区间差距等方面,对构建差别化货币政策的实施体系提出建议。     

Assessing the effectiveness of monetary policy in Kenya: Evidence from a macroeconomic model

This paper examines the effectiveness of monetary policy in Kenya based on policy simulations from a structural macroeconometric model. The analysis is conducted using the policy rate, i.e. the central bank rate (CBR) and the cash reserve ratio (CRR) with respect to the interest rate and bank lending channels, respectively. The results indicate that whereas a change in the policy rate is effective in influencing short term rates, the long term lending rates respond marginally. Consequently, the transmission to the real economy and the overall impact on inflation is minimal. However, a change in CBR has a comparatively higher impact on inflation while a change in CRR has a relatively larger impact on aggregate demand. Enhancing the effectiveness of the CBR and strengthening of the interest rate channel have the potential of anchoring inflation expectations and boosting the effectiveness of monetary policy in Kenya.     

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.     

Are there asymmetries in the response of bank interest rates to monetary shocks?

This article examines the velocity and asymmetry of the response of bank interest rates to monetary policy shocks. Using an asymmetric vector error correction model, it analyses the pass-through of changes in money market rates to retail bank interest rates in Italy in the period 1985–2002. The main results of the article are: (1) the speed of adjustment of bank interest rates to monetary policy changes increased significantly after the introduction of the 1993 Consolidated Law on Banking; (2) interest rate adjustment in response to positive and negative shocks is asymmetric in the short run, but not in the long run; (3) banks adjust their loan (deposit) rate faster during periods of monetary tightening (easing); (4) this asymmetry almost vanished since the 1990s.     

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.
