The dynamic of bank lending channel: Basel regulatory constraint

This article analyzes the impact of monetary policy on bank behavior under the Basel I regulatory framework using a dynamic model with monopolistic competition. There are two main objectives. First, we theoretically predict the dynamic model of bank lending channels under the Basel I regulatory constraint. Second, we empirically analyze the situation in Malaysia by using panel data on 23 commercial banks in the period of 1999 to 2007 by using General Method of Moments. The empirical results show that market rates on loans and policy rates are important influences on average rates of banks' loans. This has an implication that Malaysian banks have the power to set their own prices on loans as they are influenced by the change in the market rate and policy rate. We also have proven that the previous period of spread risk weighted loans and securities is statistically significant and correlated with the average loan rate, whereas risk weighted securities is also statistically significant and correlated with the average time deposit rate in both periods. This shows that the role of risk-weighted assets under the Basel I is important in influencing the optimal rates on loans and time deposits.     

Bank Interest Rate Adjustments: Are They Asymmetric?

This paper is concerned with the asymmetric adjustments between three Australian bank interest rates: a bank bill rate, a loan rate and a deposit rate. A multivariate asymmetric error-correction model is applied to capture the interplay of long-run relationships between the levels of the rates and short-run relationships between the changes in the rates. The empirical analysis, for the sample period 1990:01–2000:04, shows that interest rate adjustments, in response to positive and negative shocks, are asymmetric in the short run, but not in the long run. In particular, the results suggest that banks adjust their loan and deposit rates, in response to a change in the bank-bill rate, at a faster rate during periods of monetary easings (negative changes) than during periods of monetary tightenings (positive changes).     

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.     

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。     

前瞻性货币政策反应函数在我国货币政策中的检验

本文在泰勒等西方学者对货币政策反应函数研究的基础上,构造一个适合我国国情的前瞻性货币政策反应函数,从市场利率(同业拆借利率)、管制利率(存贷款利率)以及两者利差三个层次,通过该反应函数对我国货币政策的实证检验结果发现,一方面,该反应函数能够很好地描述同业拆借利率、存贷款利率和两者利差的具体走势,能够为我国货币政策的制定提供一个参考尺度,以衡量货币政策的松紧。另一方面,检验结果表明,三个层次的利率对预期通胀率和预期产出的反应绝大多数都不足,这说明,我国货币政策是一种内在不稳定的货币政策。     

Monetary transmission with multiple policy rates: evidence from Turkey

Quantitative easing policies have led to persistent divergence between officially announced policy rates and short-term money market rates in many economies, making it challenging to assess the stance of monetary policy in the aftermath of the global financial crisis. Lack of data variation in short-term interest rates across time dimension has made it difficult to identify the monetary transmission mechanisms. In order to shed some light on this topic, we make advantage of a specific period from Turkey during which the central bank deliberately allowed the policy rates to diverge frequently from the interbank rates due to capital flow management purposes. Using bank-level flow data from this episode, we investigate the relationship between various short-term interest rate measures and bank loan/deposit rates through panel estimation methods. Our findings suggest that interbank rates are more relevant than central bank’s officially announced rates for the transmission of monetary policy when the two diverge from each other persistently. Interbank rates particularly play a key role in the pricing of loans and deposits. These findings provide helpful guidance for evaluating the monetary stance under unconventional policies.     

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.     

Quantitative monetary policies and the portfolio composition of commercial banks

In this paper two quantitative monetary policy instruments imposed on commercial banks, i.e., a loan ceiling and an investment coefficient are analysed. The loan policy imposes a ceiling on the amount lent to the private sector; an investment coefficient imposes a floor on credits granted to the government. Both instruments facilitate, through different channels, the finance of government deficits. For the two instruments two scenario's are contrasted: a moral suasion and an imperative policy scheme. The first policy is pursued if no sanctions are imposed by the central bank; the second scheme applies if such sanctions are part of the policy.     

Competition among banks and the pass-through of monetary policy

This paper introduces monopolistically competitive financial intermediaries into the New Keynesian DSGE setting. Modelling bank market power explicitly contributes to understanding two empirical facts: (i) The short-run transmission of changes in money market rates to bank retail rates is far from complete and heterogeneous. (ii) Stiffer competition among commercial banks implies that loan rates correlate more tightly with the policy rate. In my model, the degree of monopolistic competition in the banking sector has a sizeable impact on the pass-through of changes in the policy rate. In particular, a more competitive market for bank credit amplifies the efficiency of monetary policy.     

基于流动性过剩的财政政策和货币政策协调性研究

流动性过剩是当前中国宏观经济中的突出矛盾，影响了中国经济健康有序的发展。要解决流动性膨胀问题，不应该仅仅从银行体系这个角度来考虑，而应该从整个宏观经济平衡这个更为广泛的视角去分析和研究。这意味着仅仅依靠货币当局，沿用提高存款准备金率和存贷款利率、向市场发行央行票据等现有的货币政策手段来应对流动性膨胀，难以根治问题。应在运用货币政策的同时，配合财政政策，通过两大政策的协调配合，建立起消费主导的良性经济发展模式和合理的国民收入分配格局，才是应对流动性膨胀的治本之策。     

Bank lending and interest on excess reserves: An empirical investigation

This paper econometrically tests for effects on bank lending of the Federal Reserve’s policy of paying interest on excess reserves (IOER). Following the 2008 financial crisis, US banks decreased their loan allocations and increased holdings of excess reserves. A model of bank asset allocation shows that when the rate of IOER is higher than other short-term rates, banks will switch from zero excess reserves to a regime with higher excess reserves and lower lending. Using a sample of panel data on US banks from 2000 through 2018, we find evidence of a switch to a positive excess reserve regime in the post-crisis period. Controlling for market interest rates, loan demand, and economic activity, we find that IOER accounts for the majority of the decline in bank lending after the financial crisis.     

积极的小微企业信贷政策研究

小微企业占我国企业群体的绝大部分,是社会财富的主要创造者,也是吸纳就业的主渠道,在我国国民经济中占有重要地位,但小微企业贷款难问题突出.小微企业贷款难,既有企业自身和商业银行方面的原因,更有存款准备金率政策对小银行存在歧视、资本占用系数的规定缺乏支持小微企业贷款的充分安排、贷款指标没有充分向小微企业倾斜等信贷政策方面的原因.因此,应牢固树立“小微企业贷款≠高风险贷款”的理念,将主营小微企业贷款的小银行当作发展小微企业的战略重点,降低小银行的存款准备金率,降低小企业贷款的风险权重和资本匹配系数,信贷指标分配向小微企业贷款倾斜,实施积极宽松的小微企业信贷政策.     

A note on the stabilization impact of asset-side versus liability-side constraints

This study employs a general equilibrium model of the financial sector to evaluate the impact of changing asset-side versus liability-side constraints on effective monetary control. On the basis of maximizing assumptions for individual and institutional behavior, it is possible to conclude qualitatively that asset-side constraints (e.g., a loan reserve requirement and/or a bank capital/assets ratio) automatically stabilize the economy by reducing the expected fluctuations of the rate of return on physical capital. By contrast, the stabilization impact of liability-side constraints (e.g., a deposit reserve requirement and/or a bank capital/deposits ratio) is found to be ambiguous.     

Interbank Relationships and the Credit Channel in Germany

A crucial condition for the existence of a credit channel through bank loansis that monetary policy should be able to change bank loan supply. This papercontributes to the discussion on this issue by presenting empirical evidence fromdynamic panel estimations based on a dataset that comprises individual balancesheet information on all German banks. It shows that the average bank reduces itslending more sharply in reaction to a restrictive monetary policy measure the lowerits ratio of short-term interbank deposits to total assets. A dependence on its size canonly be found if explicitly controlled for this dominating effect. Overall, the evidenceis compatible with the existence of a credit channel but the results indicate that it is weakened by the network structures that exist in the German banking system.     

Financial shocks,financial stability,and optimal Taylor rules

We assess the performance of optimal Taylor-type interest rate rules, with and without reaction to financial variables, in stabilizing an economy following financial shocks. The analysis is conducted in a DSGE model with loan and bond markets, each featuring financial frictions. This allows for a wide set of financial shocks and transmission mechanisms and can be calibrated to match the bond-to-bank finance ratio featured in the US financial system. Overall, we find that monetary policy that reacts to credit growth, a form of the so-called “leaning against the wind”, improves the ability of the central bank to achieve its mandate in the wake of financial shocks. The specific policy implications depend partly on the origin and the persistence of the financial shock, but overall not on the assignment of a mandate for financial stability in the central bank’s objective function.

The effect of economic policy uncertainty on bank valuations

This article examines how economic policy uncertainty (EPU) affects bank valuations. Using a large sample of banks over a long period, we find that EPU has a negative effect on bank valuations. One explanation for this result is that EPU reduces bank loan growth, and lower loan growth then leads to lower bank valuations. Consistent with this explanation, we find that the negative effect of EPU is more pronounced for banks with a higher ratio of loans to total assets.     

Between Mao and markets: new evidence on segmentation of the bank loan market in China

This article examines the local bank lending's dependency upon local deposits within China in the Feldstein–Horioka vein. In the case of a transition economy like China, it would be appropriate to assume the presence of a significant level of disparity in the cost of funds between State-Owned Enterprises (SOEs) and non-SOEs. For this purpose, a dataset of the provincial deposit rates and the provincial loan rates for the state and the nonstate sectors is built. Even after controlling the national- and province-specific shocks, the correlation between the local deposit rates and the local loan rates for the nonstate sector, in contrast with that for the state sector, is even higher than for the Organization for Economic Co-operation and Development (OECD) member countries. The findings suggest that serious asymmetric information problems between banks and non-SOEs might impede cross-regional lending and prevent the development of the nonstate sector within China.     

Macro effects of capital requirements and macroprudential policy

I investigate macro effects of higher bank capital requirements on the Norwegian economy and their use as a macroprudential policy instrument under Basel III. To this end, I develop a macroeconometric model where the capital adequacy ratio, lending rates, asset prices and credit interact with each other and with the real economy. The empirical results suggest that changes in capital requirements are primarily transmitted via lending rates to the other variables in the model. The proposed increases in capital requirements under Basel III are found to have significant effects especially on house prices and credit. I also derive optimal paths for the countercyclical capital buffer in response to various shocks. The buffer is found to equal its imposed ceiling of 2.5% in response to most of the shocks considered while its duration varies in the range of 1–12 quarters depending on the shock and its persistence.     

Bank asset quality & monetary policy pass-through

The funding mix of European firms is weighted heavily towards bank credit, which underscores the importance of efficient pass-through of monetary policy actions to lending rates faced by firms. Euro area pass-through has shifted from being relatively homogenous to being fragmented and incomplete since the financial crisis. Distressed loan books are a crisis hangover with direct implications for profitability, hampering banks ability to supply credit and lower loan pricing in response to reductions in the policy rate. This paper presents a parsimonious model to decompose the cost of lending and highlight the role of asset quality in diminishing pass-through. Using bank-level data over the period 2008–2014, we empirically test the implications of the model. We show that a one percentage point increase in the impairment ratio lowering short run pass-through by 3%. We find that banks with severely impaired balance sheets do not adjust their loan pricing in response to changes in the policy rate at all. We derive a measure of the hidden bad loan problem, the NPL gap, which we define as the excess of non-performing loans over impaired loans. We show that it played a significant role in the fragmentation of euro area pass-through post-crisis.
