借贷便利创新工具有效影响了商业银行贷款利率吗？

本文基于手工收集的2009—2017年中国银行业数据,利用我国借贷便利工具创新这一准自然实验,以借贷便利工具的运用需要商业银行提供合格担保品这一要求为切入点,考察了借贷便利工具对商业银行贷款利率的影响。研究发现,借贷便利工具创设后,商业银行持有的合格担保品规模越大,其贷款利率越低,且这一效应随着时间推移逐渐增强。进一步的作用机制检验发现,央行的借贷便利操作扩大了商业银行向中央银行借款规模和贷款投放规模,从而有效降低了商业银行贷款利率,也表明借贷便利工具可通过商业银行合格担保品渠道发挥作用。因此,可以通过调整借贷便利操作规模、操作利率以及合格担保品范围的方式有效影响商业银行贷款利率进而发挥对社会融资成本的调控作用。     

The countercyclical capital buffer and the composition of bank lending

Do targeted macroprudential measures impact non-targeted sectors too? We investigate the compositional changes in the supply of credit by Swiss banks, exploiting their differential exposure to the activation in 2013 of the countercyclical capital buffer (CCyB) which targeted banks’ exposure to residential mortgages. We find that the additional capital requirements resulting from the activation of the CCyB are associated with higher growth in banks’ commercial lending. While banks are lending more to all types of businesses, the new macroprudential policy benefits smaller and riskier businesses the most. However, the interest rates and other costs of obtaining credit for these firms rise as well.     

Economic policy uncertainty and the credit channel: Aggregate and bank level U.S. evidence over several decades

Economic policy uncertainty affects decisions of households, businesses, policy makers and financial intermediaries. We first examine the impact of economic policy uncertainty on aggregate bank credit growth. Then we analyze commercial bank entity level data to gauge the effects of policy uncertainty on financial intermediaries’ lending. We exploit the cross-sectional heterogeneity to back out indirect evidence of its effects on businesses and households. We ask (i) whether, conditional on standard macroeconomic controls, economic policy uncertainty affected bank level credit growth, and (ii) whether there is variation in the impact related to banks’ balance sheet conditions; that is, whether the effects are attributable to loan demand or, if impact varies with bank level financial constraints, loan supply. We find that policy uncertainty has a significant negative effect on bank credit growth. Since this impact varies meaningfully with some bank characteristics – particularly the overall capital-to-assets ratio and bank asset liquidity-loan supply factors at least partially (and significantly) help determine the influence of policy uncertainty. Because other studies have found important macroeconomic effects of bank lending growth on the macroeconomy, our findings are consistent with the possibility that high economic policy uncertainty may have slowed the U.S. economic recovery from the Great Recession by restraining overall credit growth through the bank lending channel.     

The conditioning role of performance on the bank risk-taking channel of monetary policy: Evidence from a multiple-tool regime

The study investigates how monetary policy affects bank risk-taking under a multiple-tool regime of Vietnam during 2007–2018. Particularly, we also consider the conditioning role of bank performance, broken down by bank profitability and cost efficiency, in this nexus. Using both dynamic and static panel models, we show that the liquidity injection initiated by the central bank’s asset purchases induces banks to take more risks, captured by the traditional Z-score and two alternative measures of credit risk. However, monetary policy easing through decreased interest rates is beneficial to the credit portfolio and financial stability of banks, which therefore challenges the functioning of the bank risk-taking channel. This startling result is robust across three different interest rate measures, including lending rates, refinance rates and rediscount rates. Further analysis reveals that our observed effects are alleviated for banks with higher performance — i.e., more profitable and efficient banks. This in-depth finding offers more insights into the “search for yield” incentive, based on the theory of information asymmetry and the two competing hypotheses of “bad management” and “cost skimping”.     

Does competition influence the bank lending channel in the euro area?

This paper examines how competition influences the bank lending channel in the euro area countries. Using a large panel of banks from 12 euro area countries for the period 2002–2010 we analyze the reaction of loan supply to monetary policy actions depending on the degree of bank competition. We find that the effect of monetary policy on bank lending is dependent on bank competition: the transmission of monetary policy via the bank lending channel is less pronounced for banks with extensive market power. Further investigation shows that banks with less market power were more sensitive to monetary policy only before the financial crisis. These results suggest that bank market power has a significant impact on the effectiveness of monetary policy. Therefore, wide variations in the level of bank market power may lead to asymmetric effects of the single monetary policy.     

An econometric evaluation of bank recapitalization programs with bank- and loan-level data

Public capital injections into the banking system are a comprehensive policy program aimed at reducing the financial risks faced by capital-injected banks, thereby stimulating their lending and profitability. This paper evaluates empirically Japan’s two large-scale capital injections in 1998 and 1999. We begin by extracting the treatment effects of the public injections from bank-level panel data. Using a difference-in-difference estimator in two-way fixed-effects regression models, we find that the public injections significantly reduced the financial risks faced by the capital-injected banks but did not stimulate their lending or profitability. Next, we investigate what factors impeded bank lending after the public injections using a matched sample of Japanese banks and their borrowers. By employing three-way fixed-effects regression models corresponding to the matched sample, we provide evidence that the deterioration of borrowers’ creditworthiness inhibited not only the injected banks but also the noninjected banks from lending more.     

Deposit interest rate ceilings as credit supply shifters: Bank level evidence on the effects of Regulation Q

How did deposit interest rate ceilings, an important feature of the U.S. regulatory regime until the mid-1980s, affect individual banks’ lending and the transmission of monetary policy to credit? I estimate the effect of deposit rate ceilings inscribed in Regulation Q on commercial banks’ credit growth using a historical bank level data set starting in 1959. Banks’ credit growth contracted sharply when legally fixed deposit rate ceilings were binding. Interaction terms with monetary policy suggest that the policy impact on bank level credit growth was non-linear and significantly larger when rate ceilings were in place. Bank size and capitalization mitigate these effects. At the bank level, short-term interest rates exceeding the legally fixed deposit rate ceilings identify policy induced credit supply shifts that disappeared with deposit rate deregulation and thus weakened the bank lending channel substantially since the early 1980s.     

LTV policy as a macroprudential tool and its effects on residential mortgage loans

Since the early 2000s, macroprudential policy has increasingly become part of the regulatory and supervisory framework. Likewise, the housing market has been at the center of the debate on systemic financial risk prevention. Among macroprudential tools, the purpose of the loan-to-value (LTV) ratio is to constrain mortgage loan creation. This paper is unique in that it analyzes the effectiveness of LTV on mortgage lending moderation using a large sample of more than 4000 banks from 46 countries. The analysis suggests mortgage loans have been successfully curbed in countries with a LTV policy. Size and non-performing loans are the two key characteristics to the effectiveness of LTV. When nonlinearities are considered, the average effect of LTV can be very large; however, it becomes much less effective with large banks and banks with bad loans. Our results suggest the inclusion of other macroprudential tools may have complementary effects to LTV, and for large size banks in particular.     

基于银行流动性管理视角的宏观审慎与货币政策协调研究

本文从商业银行流动性管理视角出发,探究银行微观主体行为如何影响宏观审慎与货币政策的协调。我们借鉴净稳定资金比例的设计理念,将商业银行的流动性管理行为纳入传统理论模型,刻画出两种流动性管理行为对货币政策信贷传导渠道效率的潜在影响及传导路径。在此基础上,采用我国50家商业银行2012年第1季度—2018年第2季度面板数据进行实证检验。我们发现,银行为提升长期流动性水平而进行的优化信贷资产结构的行为,能够显著提高货币政策传导效率。但是,部分净稳定资金比例较低的股份制银行和城市商业银行调整非信贷资产结构的行为则有可能降低货币政策传导效率。因此,在执行既有流动性监管措施的同时,关注与引导银行资产结构调整方式,对增强宏观审慎与货币政策的协调大有裨益。     

What happened to profitability? Shocks,challenges and perspectives for euro area banks

This paper analyses the evolution of bank profitability from 2005 to 2016, with a focus on the period covering both the global financial crisis and the euro area crisis. To accomplish this, we constructed a dataset that includes financial statement information from 310 euro area banks. Using a dual approach – a ‘bottom-up’ approach as applied by bank analysts and macroeconomists' ‘top-down’ approach, we find that the profitability of euro area banks was hit by two shocks of different nature. The Lehman Brothers collapse affected mostly big banks with diversified portfolios via losses in their securities investment. The subsequent euro area debt crisis and economic recession hit more traditional banks specialising in retail lending activities, mainly through increasing impairment costs. If the first shock had a one-off impact on bank profitability, the second shock is far more long-lasting and is still depressing the profitability of banks in peripheral Europe.

Do tourism receipts affect bank profitability? Analytical evidence from 85 tourism economies

Using data from 17,077 banks in 85 tourism economies during 1995–2016, this study analyzes the impact of international tourism receipts on banks’ profitability and hence financial stability. This study uses two-step system dynamic generalized method of moments estimator techniques to find that the tourism receipts are received through both direct and indirect channels and adversely affect bank profitability. Developing and low-income countries experience the greatest negative impact on profitability. Banks in European countries suffer the highest negative impact, whereas those in the United States are affected the least. Commercial and savings banks experience the highest negative impact of tourism. The findings of the study emphasize prudence in fiscal spending in countries where tourism constitutes a significant part of government revenue. The deleterious impact of COVID-19 on the flow of tourism revenue is likely to affect bank profitability and financial stability of the countries dependent on tourism. Therefore, it is of great significance to policy planners worldwide. The study also opens new vistas for research.     

Managing price and financial stability objectives in inflation targeting economies in Asia and the Pacific

Many central banks have adopted explicit objectives for financial stability, raising the possibility of trade-offs between price and financial stability objectives. Based on structural vector autoregressions that incorporate both monetary and macroprudential policy shocks for four inflation targeting economies in Asia and the Pacific, we analyse the role of each policy shock in explaining deviations from the other policy’s objective, by applying historical decompositions. The macroprudential measures used in the study affect credit extended to the private sector. We find that there are periods when macroprudential policy shocks have contributed to pushing inflation away from the central bank’s inflation target and when monetary policy shocks have contributed to buoyant credit, suggesting that there have been short-term trade-offs between price and financial stability objectives. However, we also find periods when macroprudential policy shocks helped stabilise inflation and monetary policy shocks contributed to financial stability.

Does market structure matter on banks’ profitability and stability? Emerging vs. advanced economies

We empirically investigate the effects of market structure on profitability and stability for 1929 banks in 40 emerging and advanced economies over 1999–2008 by incorporating the traditional structure-conduct-performance (SCP) and relative-market-power (RMP) hypotheses. We observe that a greater market share leads to higher bank profitability being biased toward the RMP hypothesis in advanced economies, yet neither of the hypotheses is supported for profitability in emerging economies. The SCP appears to exert a destabilising effect on advanced banks, suggesting that a more concentrated banking system may be vulnerable to financial instability, however, the RMP seems to perform a stabilising effect in both economies. Evidence also highlights that profitability and stability increase with an increased interest-margin revenues in a less competitive environment for emerging markets. Overall, these results suggest that although policy measures to promote competition may dampen economic rent, excessive implementation may have an undesired destabilising impact on banks.     

Implications of bank ownership for the credit channel of monetary policy transmission: Evidence from India

Using bank-level data from India, we examine the impact of ownership on the reaction of banks to monetary policy, and also test whether the reaction of different types of banks to monetary policy changes is different in easy and tight policy regimes. Our results suggest that there are considerable differences in the reactions of different types of banks to monetary policy initiatives of the central bank, and that the bank lending channel of monetary policy is likely to be much more effective in a tight money period than in an easy money period. We also find differences in impact of monetary policy changes on less risky short-term and more risky medium-term lending. We discuss the policy implications of the findings.     

How do European banks portray the effect of policy interest rates and prudential behavior on profitability?

European policy interest rates have been low and trending downwards for almost a decade now and expectations do not seem to change. Hence, in such an environment, this paper investigates whether and how banks’ prudential behavior has influenced profitability across the European banking sector from 1999 to 2015. Using a dynamic panel model, we clearly find that banks’ financial resilience, proxied by the asymmetric Z-score and two financial ratios, affects profits: more cautious banks record higher profits. This result is confirmed by the two overall measures of profitability, namely the Return on Average Assets and Equity, but not for the Net Interest Margins. Furthermore, our analysis suggests that monetary policy's main instrument adversely affects bank income. Nevertheless, when policy interest rates are particularly low, the effect on Net Interest Margin is still positive, while the effect on the overall profitability becomes negative. These results induce that European banks succeed in increasing their profitability despite a compression of their net interest income.     

Banking systemic vulnerabilities: A tail-risk dynamic CIMDO approach

This study proposes a novel framework which combines marginal probabilities of default estimated from a structural credit risk model with the consistent information multivariate density optimization (CIMDO) methodology and the generalized dynamic factor model (GDFM) supplemented by a dynamic t-copula. The framework models banks’ default dependence explicitly and captures the time-varying non-linearities and feedback effects typical of financial markets. It measures banking systemic credit risk in the three forms categorized by the European Central Bank: (1) credit risk common to all banks; (2) credit risk in the banking system conditional on distress on a specific bank or combinations of banks; and (3) the buildup of banking system vulnerabilities over time which may unravel disorderly. In addition, the estimates of the common components of the banking sector short-term and conditional forward default measures contain early warning features, and the identification of their drivers is useful for macroprudential policy. Finally, the framework produces robust out-of-sample forecasts of the banking systemic credit risk measures. This paper advances the agenda of making macroprudential policy operational.     

The real effects of relationship lending✰

This paper studies the real effects of relationship lending on firm activity in Italy following Lehman Brothers’ default shock and Europe's sovereign debt crisis, two different crisis situations where in the latter, bank solvency was at the centre of the economic shock while being more peripheral in the former. We use a large data set that merges the comprehensive Italian Credit and Firm Registers. We find that following Lehman's default, banks offered more favourable continuation lending terms to firms with which they had stronger relationships. Such favourable conditions enabled firms to maintain higher levels of investment and employment. The insulation effects of tighter bank-firm relationships were still present during the European sovereign debt crisis, especially for firms tied to well capitalised banks.     

Deposit Insurance, Capital Regulations, and Financial Contagion in Multinational Banks

Abstract:  Banking sector globalization has caused an expansion in foreign-owned bank assets. In this paper we analyse the effects of a MNB's liability structure upon its investment in a foreign country. We develop a model in which capital adequacy requirements introduce some deliberate underinvestment which counters deposit insurance-induced overinvestment. Diversification is unattractive with fixed bank capital requirements, because it reduces the expected value of the deposit insurance net. This effect applies in multinational banks (MNBs), where shocks to the home country economy alter the value of the deposit insurance net and hence affect overseas lending incentives. Thus, MNBs act as a channel for financial contagion. We discuss the policy implications of our results.
