The International Bank Lending Channel of Monetary Policy Rates and QE: Credit Supply,Reach‐for‐Yield,and Real Effects

We identify the international credit channel by exploiting Mexican supervisory data sets and foreign monetary policy shocks in a country with a large presence of European and U.S. banks. A softening of foreign monetary policy expands credit supply of foreign banks (e.g., U.K. policy affects credit supply in Mexico via U.K. banks), inducing strong firm‐level real effects. Results support an international risk‐taking channel and spillovers of core countries’ monetary policies to emerging markets, both in the foreign monetary softening part (with higher credit and liquidity risk‐taking by foreign banks) and in the tightening part (with negative local firm‐level real effects).     

Bank Mergers, Competition, and Liquidity

We model the impact of bank mergers on loan competition, reserve holdings, and aggregate liquidity. A merger changes the distribution of liquidity shocks and creates an internal money market, leading to financial cost efficiencies and more precise estimates of liquidity needs. The merged banks may increase their reserve holdings through an internalization effect or decrease them because of a diversification effect. The merger also affects loan market competition, which in turn modifies the distribution of bank sizes and aggregate liquidity needs. Mergers among large banks tend to increase aggregate liquidity needs and thus the public provision of liquidity through monetary operations of the central bank.     

Foreign bank penetration and the lending channel in emerging economies: Evidence from bank-level panel data

This paper examines the main implications of recently increasing foreign bank penetration on bank lending as a channel of monetary policy transmission in emerging economies. Using a dynamic panel model of loan growth, we investigate the loan granting behavior of 1273 banks in the emerging economies of Asia, Latin America, and Central and Eastern Europe during the period from 1996 to 2003. Applying the pooled OLS, system GMM, and panel VAR estimators, we find consistent evidence that foreign banks are less responsive to monetary shocks in host countries, as they adjust their outstanding loan portfolios and interest rates to a lesser extent than domestic private banks, independent of their liquidity, capitalization, size, efficiency, and credit risk, and although there exists a bank lending channel in the emerging economies, it is declining in strength due to the increased level of foreign bank penetration. We also explore possible driving factors for the different responses of foreign and domestic banks to monetary policy shocks by investigating foreign banks’ different behavior during banking crises and tranquil periods, the effects of mode of entry to host countries, the home-country effects, and the response of foreign banks from OECD countries vs. all foreign countries including non-OECD countries. We suggest the access of foreign banks to funding from parent banks through internal capital markets as the most convincing explanation.     

The Effects of Liquidity Regulation on Bank Demand in Monetary Policy Operations

We estimate the effects of the liquidity coverage ratio (LCR), a liquidity requirement for banks, on the tenders that banks submit in Term Deposit Facility operations, a Federal Reserve tool created to manage the quantity of central bank reserves. We identify these effects using variation in LCR requirements across banks and a change over time that allowed term deposits to count toward the LCR. Banks subject to the LCR submit tenders more often and submit larger tenders than exempt banks when term deposits qualify for the LCR. These results suggest that liquidity regulation affects bank demand in monetary policy operations.     

Macroeconomic Factors and Microlevel Bank Behavior

We analyze the link between banks and the macroeconomy using a model that extends a macroeconomic VAR for the U.S. with a set of factors summarizing conditions in about 1,500 commercial banks. We investigate how macroeconomic shocks are transmitted to individual banks and obtain the following main findings. Backward‐looking risk of a representative bank declines, and bank lending increases following expansionary shocks. Forward‐looking risk increases following an expansionary monetary policy shock. There is, however, substantial heterogeneity in the transmission of macroeconomic shocks, which is due to bank size, capitalization, liquidity, risk, and the exposure to real estate and consumer loans.     

流动性、银行间市场摩擦与借贷便利类货币政策工具

通过内生引入流动性短缺银行(拆入行)对流动性盈余银行(拆出行)的流动性需求机制,本文构建了一个包含银行间市场的DSGE模型,对借贷便利类货币政策工具的传导机制和传导效果进行了理论和实证研究。研究表明:(1)负向冲击会同时增加拆入行和拆出行对流动性的预防性需求,在经济形势不确定的情形下,拆出行不会很快恢复对拆入行的流动性供给,引起银行间市场流动性缺口放大和市场失灵。(2)由于仅依赖银行间市场自发回归稳态的过程太过缓慢,需要央行进行流动性干预。借贷便利类工具可以通过引导贷款市场定价和流动性效应这两个渠道来影响银行融资可得性,进而降低银行间市场流动性风险对宏观经济的负面影响。(3)借贷便利类货币政策工具的影响效果边际递减,央行可根据借贷便利操作的收益和成本,制定最佳的反应程度参数。     

经常账户冲击、资本账户管理与中央银行货币政策操作

经常账户负向冲击及引发的宏观变量联动性通常对各经济体央行货币政策操作构成挑战。本文构建了融入经常账户冲击的小型开放经济DSGE模型,比较了采取不同资本账户管理工具(数量型和价格型)情景下,央行执行数量型货币政策规则、盯住CPI通胀泰勒规则、盯住PPI通胀泰勒规则下,经常账户负向冲击对货币政策操作的异质性影响及传导机制,并进行了福利分析。主要结论如下:第一,经常账户负向冲击将对本国央行货币政策操作构成一定影响;第二,资本账户管理可以成为缓冲经常账户负向冲击的防火墙,价格型资本账户管理工具与盯住PPI通胀泰勒规则相结合造成的福利损失较小;第三,经常账户贸易端与收益端双重负向冲击对一国货币政策操作的影响更大,但公众预期到的经常账户恶化对货币政策操作的影响将有所减弱。本文认为,转型经济体央行应倾向于执行价格型货币政策规则,最优货币政策应在稳定价格水平与缓释风险方面进行权衡,适度降低对名义汇率的关注度,稳慎推进资本账户开放进程,并可优先选择价格型资本账户管理工具。

Do foreign investors insulate firms from local shocks? Evidence from the response of investable firms to monetary policy

Extant research shows that stock returns of investable firms are highly sensitive to foreign market and global information shocks, suggesting that having foreign investors might insulate investable firms from shocks to local fundamentals. Examining 24 emerging markets, we find that both investable and non-investable firms are sensitive to local monetary policy shocks. This allays the concern that emerging-market opening reduces the efficacy of local monetary policy. We also find that in 11 countries (46% of our country-sample), investable firms are more sensitive to local shocks than non-investable firms. Differences in leverage, stock liquidity, size, domestic product-market exposure, or industry cyclicality do not drive this finding.     

流动性覆盖率监管会影响货币政策传导效率吗？——来自中国银行业的证据

本文从流动性覆盖率监管要求出发,探讨了流动性监管与货币政策的协调机制问题。我们将流动性覆盖率监管要求纳入传统的Monti-Klein模型中,推导出流动性覆盖率监管对货币政策传导效率的影响及其作用机制。在此基础上,采用手工收集的我国65家商业银行2015—2019年半年度面板数据对理论假设进行实证检验。研究发现,流动性覆盖率监管要求会对货币政策传导效率产生影响,但这种影响取决于流动性监管约束下商业银行流动性管理行为的选择。商业银行主动调整融资结构、增强负债质量的行为在提高银行短期流动性水平的同时,也能显著提高货币政策传导效率,而流动性资产的囤积则可能降低货币政策传导效率。因此,应客观看待流动性覆盖率监管对货币政策传导效率的影响,引导商业银行的流动性管理行为,这将有助于实现流动性监管与货币政策有效传导的“双赢”目标。     

Real liquidity and banking

In an economy where banks take numeraire goods, so called money, as deposits, money allows depositors suffering preference shocks to withdraw from banks prematurely without liquidation of real investment. If real liquidity, defined as the real value of the monetary base, is low, the amount of payment liquidity, constrained by the velocity of money, limits the short-term price level of investment goods before banks can settle their long-term loan contracts. This leads to an attractive nominal long-term investment return and over-investment. Allowing for inside money, that is, bank deposits, to be used for payment can improve social welfare but cannot fully resolve the liquidity shortage problem as the short-term interest rate offered by banks is constrained by the threat of bank runs. In the presence of systemic liquidity shocks, the price-adjustment mechanism cannot take full effects with insufficient payment liquidity, which can lead to non-zero profits for banks. Exchanging investment goods for numeraire goods through international trade can improve social welfare.     

全球性因素对中国宏观经济及货币政策有效性的影响

本文首先对全球性因素与中国主要宏观经济变量之间的协同性进行了定量研究,并探讨了协同效应的历史演变,然后实证分析了1998-2011年全球性因素对我国货币政策有效性的影响及其动态变化。通过因子增强型向量自回归模型的实证分析,我们发现,世界经济与中国宏观经济之间呈现出一定的协同性。同时,全球性因素对各经济变量的解释力度随着时间的变化有着不同的表现,但没有证据表明它已成为系统更重要的因素。全球性因素引起了中国货币政策传导机制的部分改变,然而,全球性因素在中国不同经济变量响应货币冲击中有着不同的影响,由于全球性因素,某些经济变量对货币冲击的调整幅度和方向、持续性反应和时滞期发生了一定的变化。然而,全球性因素并没有使得我国的货币政策传导机制发生系统性、根本性的改变。     

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。

货币政策对流动性风险的影响——基于银行信贷行为视角

本文基于我国现实背景和《巴塞尔协议Ⅲ》,利用2008年至2017年间194家商业银行的相关数据,对我国银行净稳定资金率进行了度量,并在此基础上,检验了货币政策对我国商业银行流动性风险的影响,探究了其影响机理和传导渠道。研究表明:扩张型货币政策会提高商业银行的流动性风险;不同经济环境下,货币政策对流动性风险的影响存在差异但不具备异质性;不同类型的商业银行中,货币政策对流动性风险的影响不具有异质性;在货币政策对流动性风险的影响中,银行信贷行为是重要的传导渠道。因此,央行可基于货币政策对流动性风险的影响差异进行相机抉择;商业银行则要加强信贷规模和质量的管理,优化资产结构,通过弱化信贷渠道作用来降低货币政策对银行流动性风险的不良影响。     

量化宽松货币政策的理论、实践与影响

全球金融危机已使全球经济陷入衰退,为应对危机各国央行不断降息。随着短期利率接近于零,美、日、英等主要国家的央行转而求助于"量化宽松货币政策",即通过购买长期国债等方式向经济注入巨量的流动性。全球大规模采取量化宽松政策在历史上尚属首次,对世界经济和中国经济都将产生难以估量的影响,对此有必要进行深入的分析。为此,本文在对量化宽松货币政策的理论基础进行分析的基础上,进一步研究了日本量化宽松政策实践的经验与教训及其影响,并提出相应的政策建议。     

美联储政策变化、国际资本流动与宏观经济波动

本文构建包含国际投资者、外资企业和银行流动性冲击的DSGE模型来探究美联储货币政策变动和政策不确定性对我国宏观经济的影响和作用机制。研究发现:(1) 美联储加息会导致我国产出、投资和通货膨胀的下降、汇率贬值、国际资本外流和银行系统流动性紧张。随着金融摩擦程度的增加和银行杠杆率的上升,美联储加息对我国产出、投资和资产价格的负面影响会进一步增强。(2) 美联储货币政策不确定性的增加会直接导致外资企业的投资、劳动需求和产出的下降,并对我国总产出、总投资和资产价格产生明显的负向外溢效应,进一步加剧我国宏观经济的波动。(3)为应对美联储的利率变动,适当限制国际资本流动能有效稳定我国经济波动和改善社会福利,而实施固定汇率和央行盯住美国利率的政策会加大宏观经济的波动,并导致社会福利下降。     

Banks’ external financing costs and the bank lending channel: Results from a SVAR analysis

We analyze the dynamic response of banks’ financing costs to structural, macroeconomic shocks, which we identify by imposing combinations of zero and sign restrictions on impulse responses. For the estimation we combine US bank balance sheet data from the Call reports with macroeconomic aggregates over the period from 1984Q1 to 2007Q3. We find that banks’ financing costs mainly respond to monetary policy and aggregate demand shocks. Furthermore, funding costs of undercapitalized and illiquid banks increase more strongly after a contractionary monetary policy shock as compared to better capitalized and more liquid banks. These results provide support for the view that banks’ financing costs represent an important element of the bank lending channel.     

Euro area banking and monetary policy shocks in the QE era

This paper assesses the effects of monetary policy shocks on the macroeconomy and the euro area banking sector after the global financial crisis. First, financial risk-return indicators of the banking sector based on a compound option-based structural credit risk model are embedded in a large macro-financial quarterly database covering the period 2008Q4–2019Q4. Second, a SFAVAR identifies and estimates the shocks’ responses relating them to the endogenous build-up of banks’ vulnerabilities which are consistent with the internally coherent structure of the credit risk model. By introducing structure in the understanding of banks’ asset-liability management behavior following monetary policy shocks, the research strategy contributes to disentangling results that are often mixed in the empirical literature. The study finds that unconventional monetary policy, in particular the Asset Purchase Program of the European Central Bank, seems to have been more successful than conventional monetary policy in raising output and inflation. The desired boost to bank lending has been muted and loan cyclicality has varied across countries and loan types. The performance of the banking sector following monetary policy shocks can be characterized by a drop in expected return on equity and assets, a relaxation of lending conditions and increased correlation between banks’ assets return and the market return, a mechanism pointing to enhanced risk-taking. While banks’ probabilities of default fall following monetary policy shocks, the price of risk increases. Banks’ net worth rises via higher market capitalization and implied assets value together with lower volatility, despite often incurring more debt. Risk-taking in the banking sector may pose a risk to financial stability, especially if its effects on banks’ vulnerability spread and increase systemic risk. The unintended endogenous build-up of macro-financial vulnerabilities may need to become part of monetary policymaking.     

Credit Markets and the Propagation of Monetary Policy Shocks

This paper analyzes the propagation of monetary policy shocks through the creation of credit in an economy. Models of the monetary transmission mechanism typically feature responses that last for a few quarters contrary to what the empirical evidence suggests. To propagate the impact of monetary shocks over time, these models introduce adjustment costs by which agents find it optimal to change their decisions slowly. This paper presents another explanation that does not rely on any sort of adjustment costs or stickiness. In our economy, agents own assets and make occupational choices. Banks intermediate between agents demanding and supplying assets. Our interpretation is based on the way banks create credit and how the monetary authority affects the process of financial intermediation through its monetary policy. As the central bank lowers the interest rate by buying government bonds in exchange for reserves, high productive entrepreneurs are able to borrow more resources from low-productivity agents. We show that this movement of capital among agents sets in motion a response of the economy that resembles an expansionary phase of the cycle.
