资本充足率、存款准备金率与货币政策银行信贷传导——基于银行业市场结构的分析

基于垄断竞争的银行业市场结构,研究银行在受到资本充足率和存款准备金率双重约束条件下,在面对货币政策冲击的情况下所做出的最优信贷决策行为。通过构造贷款市场总体均衡模型,得出以下结论:当银行满足资本充足率和存款准备金率要求时,货币政策的银行信贷传导渠道表现出有效性;而当贷款市场中的银行不能满足资本充足率或存款准备金率要求时,货币政策的银行信贷传导渠道则表现出无效性。     

Monetary policy transmission through the bank lending channel in Thailand

This paper investigates the strength of the bank lending channel in the transmission of monetary policy in Thailand. Bank behavior is captured by quarterly balance sheet data for ten commercial banks of diverse size for the period 2007-2016. Based on a flexible form profit function, bank supply and demand equations are estimated that capture lending and funding choices. The estimation results are used to derive time-dependent supply and demand elasticities which are then combined with estimates of pass-through from the policy rate to retail rates to simulate the dynamic impact of a monetary tightening on bank portfolio allocations. Due to pass-through differentials among retail interest rates, an increase in the policy rate is shown to raise the cost of loan-production relative to the return on loans, thereby motivating banks to contract their lending. Small banks show a greater degree of loan contraction than large banks because large banks are better able to fund continued lending through debt issuance. Because the Thai economy relies heavily on bank loans, these findings suggest that the bank lending channel is an important conduit for the transmission of monetary policy in Thailand.     

The lending channel of monetary policy in Indonesia

This study evaluates the bank lending channel of monetary policy in Indonesia by using quarterly bank-level data over the period of 2005-2016. I find that the lending channel of monetary policy works for all banks, both large and small. The results suggest that higher capital buffers and better liquidity positions moderate the impact of changes in monetary policy on credit growth for large banks, while capital buffers and liquidity positions do not alter the strength of the lending channel for small banks. The findings indicate that the central bank can use prudential instruments affecting capital buffers and liquidity positions for managing the strength of adjustment in the monetary policy interest rate on bank credit growth.     

Bank dependency on foreign funding and global liquidity shocks: The importance of US monetary policy for a developing country

We examine international spillover effects of US monetary policy on bank lending in Cambodia, using unique data about loan disbursements and the funding structures of Cambodian banks from 2013Q1 to 2019Q2. The banking sector in a developing country is likely dependent on foreign funding, while the dependency could be the source of vulnerability to international monetary and economic conditions. We empirically document that US monetary policy is likely to be transmitted to Cambodian bank lending through foreign funding. We also document that Cambodian banks change their risk-taking behavior in response to the spillover effects of US monetary policy. Furthermore, these results are robust for US monetary policy, but weak and not robust for the monetary policies of the Cambodian bank’s major shareholders’ home countries, suggesting that US monetary policy should be primarily taken into account in supervising banks that are reliant on foreign funding, in addition to domestic economic conditions.     

Does bank competition affect the transmission mechanism of monetary policy through bank lending channel? Evidence from India

This paper empirically investigates how intensified competition in the Indian banking affects the transmission of monetary policy through bank lending channel over the period 1997–2017. Additionally, this study examines the impact of deposit and loan market channels on bank’s credit growth. Results obtained through two-step system-GMM reveal that a higher degree of market power weakens the monetary policy transmission mechanism for the entire banking industry and across ownerships. Results show that higher market power in the deposit and loan markets weakens the impact of monetary policy on bank loan supply. The findings of this study extend important policy measures that can strengthen the transmission mechanism of monetary policy by reducing the adverse effects of changes in bank competition.     

Financial Deregulation and the Bank Lending Channel in Developing Countries: The Case of Indonesia

The dominant role of commercial banks as a source of finance and the considerable asymmetry of information in financial markets in developing countries have raised an argument that the bank lending channel of monetary transmission mechanism would be very important in such countries. This study addresses the issue by investigating empirically whether there are differential effects of monetary policy on banks' balance sheets, and its implications to the existence of the bank lending channel of monetary policy in Indonesia, especially since the early 1980s when the government adopted a policy of financial deveculation. We find significant differences of balance sheet behaviour across bank classes in response to a change in monetary policy, consistent with the predictions of the bank lending view. We also found that because of access to foreign funds and the existence of bank loan commitment, the monetary policy was unable to constrain loan supply by the large (state) banks, indicating that the bank lending channel operates through smaller (non-state) banks.     

Does a large loss of bank capital cause Evergreening? Evidence from Japan

Using the real estate lending share of the bank’s loan portfolio at the peak of the land-price bubble as an instrument for bank capital, we identify the impact of capital adequacy on the allocation of bank lending under the Basel regulatory framework. We find that, in Japan, a large loss of bank capital caused by the regulator’s excessively tough stance towards banks not only induced the contraction of the bank lending supply but also the banks’ reallocation of their lending portfolios to financially unhealthy industries with a higher concentration of non-performing loans.     

The economic consequences of the TARP: The effectiveness of bank recapitalization policies in the U.S.

This study empirically analyzes the impact of the United States’ bank recapitalization program, the centerpiece of the United States’ $700 billion Troubled Asset Relief Program (TARP), on bank portfolios. Through superior empirical analysis and correct model specification, our findings overturn much of the existing literature on the effectiveness of capital injections into the banking sector in Japan and the United States. We show that the TARP program did not achieve the stated policy objective of stimulating bank lending. On the contrary, we find evidence that recipient banks grew assets significantly slower, particularly heavily risk-weighted assets such as loans. These findings are robust to various empirical specifications, including two-stage least squares estimation using instrumental variables, difference-in-difference techniques and generalized method of moments. These techniques control for pre-existing trends in loan growth while addressing potential endogeneity bias.     

Why do commercial banks hold government bonds? The case of Japan

We investigate the determinants of the demand for Japanese government bonds (JGBs) by commercial banks in Japan. In particular, by estimating portfolio equations for JGB demand and bank loans, based on a panel data set from the late 1990s to the 2000s, we rigorously test the popular assertion that the long stagnation of the real economy caused a shift in the portfolios of commercial banks from bank lending to JGBs. We find that the popular assertion is not empirically supported. Rather, the portfolio shift from loans to JGBs has been caused by a fall in the ratio of the loan rate to unit lending costs, or the bank’s price–cost margin for lending.     

Some Evidence on the Relevance of Bank Behaviour for the Lending Channel in The Netherlands

This paper studies the behaviour of Dutch banks. We test the adjustment of banks' balance sheets in times of monetary policy changes during the period 1957–1991. As a reaction to a policy change, banks basically have two alternatives to adjust their net money creation: (1) sell securities in public capital markets, and/or issue long-term liabilities, and (2) change domestic loan supply. If banks opt for the latter a lending channel may be relevant, even in a small open economy with a fixed exchange rate and a high degree of international capital mobility. We test for the effectiveness of both indirect and direct instruments of monetary policy. It turns out that in case of changes in the official interest rate, the volume of bank loans is not affected and that banks display a kind of buffer-stock behaviour by diminishing their publicly traded assets. In situations with quantity restrictions on the growth of net money creation, however, the volume of loans is affected significantly when the quantity restriction is withdrawn thereby fulfilling a necessary condition for the bank lending channel to be effective.     

Heterogeneity in lending and sectoral growth: evidence from German bank-level data

This paper investigates whether heterogeneity across firms and banks matters for the impact of domestic sectoral growth on bank lending. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996–2002 period. Our results show that firm heterogeneity and bank heterogeneity affect how lending responds to domestic sectoral growth. We document that banks’ total lending to German firms reacts pro-cyclically to domestic sectoral growth, while lending exceeding a threshold of €1.5 million to German and foreign firms does not. Moreover, we document that the response of lending depends on bank characteristics such as the banking groups, the banks’ asset size, and the degree of sectoral specialization. We find that total domestic lending by savings banks and credit cooperatives (including their regional institutions), smaller banks, and banks that are highly specialized in specific sectors responds positively and, in relevant cases, more strongly to domestic sectoral growth.

Is There a Bank Lending Channel in Southern African Banking Systems?

Abstract: Macroeconomic models currently used by policymakers generally assume that the functioning of financial markets can be fully summarized by financial prices, because the Modigliani and Miller (1958) theorem holds. However, the assumption that this theorem holds is questionable. This paper argues that there are frictions in the market which traditional models based on the Modigliani and Miller theorem fail to take into account in explaining how monetary policy and other shocks are transmitted to the economy and points to new directions. A comprehensive macroeconomic model should incorporate financial market interactions to enhance the understanding of the transmission mechanisms of monetary policy and other shocks. If market dynamics are not taken into account, macroeconomic models used by policymakers may point to wrong policy choices. Motivated by the lack of assessment of the recently launched financial reforms, deregulation, consolidations, financial innovations and joint payment systems, the paper assesses the process of monetary transmission mechanism by investigating evidence of a bank lending channel in SADC during the period 1990–2006 using data from the banking sector. Data from a panel of banks is used to identify shifts in the loan supply curve in response to changes in monetary policy using a vector autoregression (VAR) model. Although the results are mixed the paper generally reports the existence of a bank‐lending channel in all SADC countries in the sample. The take‐off point for monetary policy effects differs from one country to another.     

Spillovers of banking regulation: the effect of the German bank levy on the lending rates of regional banks and their local competitors

During the financial crisis numerous European governments decided to rescue domestic banks with public funds to prevent a collapse of the banking system. To internalize the public costs, bank levies have been introduced in many countries. This paper analyzes the German bank levy which was implemented from 2011 till 2014. We examine not only if banks shift the cost of the levy to their customers’ lending rates, but also whether there are spillovers to their local competitors. The German savings and cooperative banks are a perfect setting to study such effects as they only operate within well-defined regions, allowing us to identify their local competitors. Additionally, only some of them are subject to the levy due to a tax allowance. Firstly, we find that a bank that has to pay the bank levy raises its lending rate by about 0.14 percentage points. Secondly, we examine whether the increased lending rates of paying banks spill over to their local competitors. We find this indirect effect to be about one third of the size. Lastly, adverse effects of the levy on paying banks’ loan supply growth are absorbed by their competitors to a certain extent.     

Bank loans and the effects of monetary policy in China: VAR/VECM approach

In this paper, we test the differential effects of monetary policy shock on aspects of banks' balance sheets (deposits, loans, and securities) across bank categories (aggregate banks, state banks, and non-state banks) as well as on macroeconomic variables (output, consumer price index, exports, imports, and foreign exchange reserves). We do so by estimating VAR/VEC Models to uncover the transmission mechanisms of China's monetary policy. Also we identify the cointegrating vectors to establish the long-run relationship between these variables. By using monthly aggregate bank data and disaggregated data on bank and loan types from 1996 to 2006, our study suggests the existence of a bank lending channel, an interest rate channel and an asset price channel. Furthermore, we discuss and explore the distribution and growth effects of China's monetary policy on China's real economy. In addition, we investigate the effects of China's monetary policy on China's international trade. Finally, we identify the cointegrating vectors among these variables and set up VEC Models to uncover the long-run relationships that connect the indicators of monetary policy, bank balance sheet variables and the macroeconomic variables in China.     

No lending relationships and liquidity management of small businesses during a financial shock

We investigate the determinants of the end of lending relationships with banks using small business data. We also investigate how small businesses without lending relationships financed credit demand during the global financial shock. First, we find that firms with lower growth, low working capital, and high internal cash were more likely to end lending relationships with banks. Supply-side effects on the determinants of the end of relationships are insignificant. Second, when firms experienced credit demand during the financial shock, those with lending relationships increased bank borrowings while those without lending relationships reduced internal cash. Third, firm performance (in terms of profitability) was neither lower nor higher for firms that did not have lending relationships with banks during the shock period.     

Bank profitability and the bank lending channel: Evidence from China

This paper uses bank-level data to investigate whether the impact of monetary policy on bank lending depends on the characteristics of Chinese banks during the period 1985–2007. We find that the impact of monetary policy on lending is weaker for larger banks and banks with lower levels of liquidity, and that banks’ responses to monetary policy do not necessarily vary according to their capital. Further, to identify the bank lending channel more clearly, we test whether the impact of monetary policy varies according to profitability. The results show that profitable banks tend to be less sensitive to monetary policy, because when tight monetary policy leads to a fall in deposits, less profitable banks face a higher cost of capital.     

The transmission mechanism of monetary policy in Japan: Evidence from banks' balance sheets

We examine how banks' responses to monetary policy vary according to their balance sheet using Japanese bank data from 1975 to 1999. We find that the effect of monetary policy on lending is stronger for banks that are smaller, less liquid, and more abundant with capital. The effects of bank balance sheet on monetary transmission are different by bank types, policy stances and borrowers' industries. Our results imply that a lending channel of monetary transmission exists, that the effect of expansionary monetary policy is attenuated if banks' capital is scarce, and that the effect of monetary policy on the allocation of funds depends on banks' balance sheets.

Bank Lending and Economic Growth of Chinese Cities

Using a city-level dataset over the period 2004-2006,the present study investigates the relationship between bank lending and the economic growth of Chinese cities.Unlike past studies,we divide bank lending into loans from three types of banks:foreign banks,city banks and other banks.Our findings are threefold.First,the lending of foreign banks exhibits a strong and positive association with the economic growth of Chinese cities. Second,foreign direct investment in the sampled cities enhances the lending effects of foreign banks,but reduces the lending effects of other banks on the economy of Chinese cities.Third, the effects of city competitiveness are similar to those of foreign direct investment;that is,city competitiveness augments the lending effects of foreign banks but reduces the lending effects of other banks.

US vs. euro area: Who drives cross-border bank lending to EMs?

This paper analyzes the drivers of cross-border bank lending to 49 Emerging Markets (EMs) during the period 1990Q1–2014Q4, by assessing the impact of monetary, financial and real sector shocks in both the US and the euro area. The literature has traditionally highlighted the influence of US monetary policy on driving cross-border bank flows, and more recently the importance of both US and Euro Area (EA) financial/banking sectors’ related variables. Our contribution is the simultaneous analysis of the role of these US and EA drivers, as well as their interactions with real sector shocks. We corroborate the negative impact of US monetary policy tightening on cross-border lending to EMs, but we find that EA monetary policy seems to have an impact mostly on Emerging Europe, reflecting the fact that cross-border lending to most other EM regions is dollar denominated. We also find that real sector shocks in both the US and EA trigger an increase in cross-border lending, but less in EA when modeling the financial sector. Finally, for financial sector shocks, such as those associated with a decrease in bank leverage, our results indicate a broad-based overall contraction of cross-border lending if the shock originates in the US, and heterogenous effects across borrowing regions if the shock originates in the EA.
