Over- and Underbidding in Central Bank Open Market Operations Conducted as Fixed Rate Tender

Abstract. Open market operations play a key role in allocating central bank funds to the banking system and thereby in steering short‐term interest rates in line with the stance of monetary policy. Many central banks apply so‐called ‘fixed rate tender’ auctions in their open market operations. This paper presents, on the basis of a survey of central bank experience, a model of bidding in such tenders. In their conduct of fixed rate tenders, many central banks faced specifically an ‘under‐’ and an ‘overbidding’ problem. These phenomena are revisited in the light of the proposed model, and the more general question of the optimal tender procedure and allotment policy of central banks is addressed.     

A QUEST FOR UNFETTERED CREDIT: HOW MONETARY POLICY DRIVES CREDIT RISK TRANSFER OF STRUCTURED FINANCE PRODUCTS

This study examines the effects of monetary policy contractions on bank loans to households and firms and instruments in three different credit risk transfer (CRT) capital markets over two separate time periods (1995–2006 and 2007–2015). The findings show that in both periods, banks decrease business lending but increase lending to consumers through a combination of mortgage, auto, credit card, and student loans from more liquidity produced by consumer‐related CRT activity. Additional results reveal relative CRT movements toward securitized mortgages from bank mortgage debt over both periods and toward securitized and insured business loans from bank business debt in the latter period, which suggest vulnerabilities among interconnected credit markets.

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 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.     

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.     

The effect of US stress tests on monetary policy spillovers to emerging markets

This paper explores the transmission of US monetary policy through US banks to emerging market economies (EMEs) and the role that stress tests play in this transmission. Data on US banks’ monthly commercial and industrial loan originations shows that: (a) US bank lending to EMEs was sensitive to domestic monetary policy changes during the zero‐lower bound period. (b) Effects of monetary easing were heterogeneous across banks and depended on banks’ stress test results, a proxy for their capital strength. Only banks that comfortably passed the stress tests issued more loans to EME borrowers. (c) Effects of monetary tightening were more similar across banks. (d) Banks shifted their lending to safer borrowers within EMEs in response to monetary easing, leaving the risk of their overall loan books unchanged. These results support the hypothesis that bank capital affects the transmission of easier monetary policy, including across borders. We conjecture that bank lending to EMEs during the zero‐lower bound period would have been even higher had the United States not introduced stress tests for their banks.     

BANK MERGERS AND ACQUISITIONS – AN EVALUATION OF THE ‘FOUR PILLARS’ POLICY IN AUSTRALIA*

This paper examines the efficiency consequences of bank mergers and acquisitions with particular reference to the ‘four pillars’ policy preventing mergers among the four major banks. Using data envelopment analysis, the technical efficiencies of banks operating in Australia over the period from 1983 to 2001 are estimated. A second‐stage regression is used to evaluate ex‐post efficiency performance of banks involved in mergers and acquisitions. The empirical results demonstrate that for the time being mergers among the four major banks may result in much poorer efficiency performance in the merging banks and the banking sector.     

Financing Channels and Monetary Policy in a Dual Banking System: Evidence from Islamic Banks in Indonesia

Using Indonesian Islamic banking data from 2003 to 2014, this article employs a panel regression methodology to investigate the responses of Islamic banks to changes in financing rates and monetary policy, which may differ depending on their characteristics. The results suggest that the financing rate has a negative impact on financing at Islamic banks, while bank‐specific characteristics have a positive influence on it. The size and amount of capital have a greater impact than liquidity on financing at Islamic banks. However, changes in monetary policy are insignificant on bank financing, which implies that the transmission of monetary policy through the Islamic segment of the banking sector is weak. Furthermore, the weak impact of monetary policy on bank financing can be explained by the dramatic expansion of Islamic banks during the sample period, which contributed to a substantial increase in deposit growth and a high liquidity position.     

GOVERNMENT BOND YIELDS AT THE EFFECTIVE LOWER BOUND: INTERNATIONAL EVIDENCE

Empirical evidence on the potential impact of central bank policies on government bond yields at the effective lower bound (ELB) is presented for nine economies. We quantify the content of central bank communications and consider international policy spillovers. Yields at the medium‐to‐longer end of the yield curve remain responsive to news for a few years after the ELB is reached. Yields become more sensitive to the content central bank communication at the ELB. Our results provide further evidence that central bank communication is an important element of monetary policy making when the interest rate tool loses efficacy. (JEL E52, E58, G12, F42)     

货币政策对金融生态的影响机理及实证检验——基于上市商业银行面板数据的分析

传统的货币理论忽视了货币政策对银行风险承担及金融生态的影响,文章从商业银行的微观视角出发研究了货币政策对金融生态的影响机理。理论层面,金融生态与货币政策制度供给、传导机制和有效性相互关联,货币政策则通过资产价格或估值机制、收入及现金流机制、追求收益机制、杠杆调整机制、道德风险机制和风险转移机制影响商业银行的风险承担;实证层面,构建了货币政策影响商业银行信贷投放和风险承担的数理模型,选取国有和股份制两类共12家上市商业银行2008-2013年的面板数据进行固定效应模型实证检验。结果表明,宽松货币政策导致商业银行的信贷投放规模增加、风险承担意愿增强,有利于优化金融生态,反之则反是;国有商业银行对货币政策变化更敏感,而股份制商业银行对金融生态更敏感。因此,在我国宏观经济管理中,需要货币政策与宏观审慎政策相互协调配合。     

基于DSGE模型的货币政策对银行风险承担影响研究*——兼论货币政策的应对

本文着力研究货币政策对商业银行风险承担的影响机制，并在此基础上分析货币政策应当如何应对。为此，本文构建了DSGE模型对比分析银行风险承担行为的传导机制，结果显示在信息不对称和有限债务的条件下，银行存在着道德风险，会过度地主动承担风险。为应对银行风险承担行为造成的低效率，本文设计了“最优”货币政策规则：货币政策应适当容忍通货膨胀的波动，优先关注实际利率，以降低由银行风险承担行为所导致的社会福利损失。     

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.     

Transparency and central bank losses in developing countries

Recent evidence shows central banks suffering from losses in some developing countries. This is a surprise to economists and policymakers. At the same time, these banks are asked to conduct monetary policy within a more transparent framework. Therefore, this paper seeks to answer the following question: Would more transparency in developing countries suffering from central bank losses be beneficial?This paper shows that the cost constraints of conducting monetary policy, central bank losses, in both transparency and opacity alike is significant and affects positively the error of the private sector in expected inflation rate and the output gap. In a country suffering from central bank losses, the expected benefits of transparency and the existence of cost constraint move in two opposite directions. As a result, it is unwise for developing countries suffering from central bank losses to focus on transparency. Priority should be given to fixing monetary policy and to developing financial markets.     

INTERNATIONAL CREDIT CHANNEL OF MONETARY POLICY: AN EMPIRICAL NOTE

A longstanding macroeconomic issue is how monetary policy affects the real economy. There are economists placing an emphasis on the role of bank lending in monetary transmission. Their view, called the credit view, is that a monetary tightening shifts the supply schedule of bank loans left, thereby forcing bank‐dependent borrowers to cut back on expenditures. In the literature, the credit view is typically studied in a closed‐economy context. In reality, however, banks make international loans through their overseas branches and subsidiaries. This suggests that the credit view should be studied in an open‐economy context. This paper proposes the international credit view: a monetary‐policy shock originated in one country propagates to another through banks’ reallocation of funds between the two countries. For testing the hypothesis, Australia and New Zealand provide an excellent case to study. This is because Australian‐owned banks dominate the banking market in New Zealand. This paper aims to test the international credit view within a framework of vector auto‐regression models. A significant and robust finding is that the supply schedule of loans shifts left in New Zealand after a monetary tightening in Australia.     

Are monetary policy shocks causal to bank health? Evidence from the euro area

Despite considerable efforts of the European Central Bank (ECB) to support bank intermediation after the 2008 financial crisis, the recovery of euro area banks remained incomplete. Although many studies indicate that central banks can influence the stock prices of firms through their policy actions and communication, a knowledge gap exists as to whether the ECB's monetary policy can influence bank health. Through a high-frequency identification approach, this study reveals that the causal effect of conventional monetary policy action and communication by the ECB on bank stock prices differed over time, whereas its influence on bank financing costs was robust. This study provides new evidence showing that information effects related to policy easing surprises in the aftermath of the 2008 financial crisis hampered the ECB efforts to improve bank health and that its Odyssean communication signals (related to forward-looking announcements of policy easing) supported bank health during this phase. Local projections suggest that the response of banks to monetary policy shocks displayed some persistence, where ECB policy surprises and communications that shifted up (down) the yield curve were normally positive (negative) for bank health. The findings solicit a new perspective when assessing the influence of the ECB's monetary policy measures on euro area banks.     

Le Pont de Londres: Interactions between monetary and prudential policies in cross‐border lending

Using two unique confidential datasets summarizing the cross‐border lending of banks in France and the UK, we examine whether recipient‐country prudential policies can help to reduce the spillover effects of euro‐area (EA) monetary policy. We address this question from a novel angle, focused on the role of international financial centres, by considering differences in bank size and location (lending from French headquarters vs. from French affiliates located in the UK). For small French banks that lack a presence in international financial centres, the response of direct cross‐border lending from France to EA monetary policy is partially offset by recipient‐country prudential policy. For larger banks, however, the offsetting effect applies only to lending that passes through foreign affiliates located in London. This suggests the existence of a “London Bridge”: banks adapt their flows to the UK conditional on EA monetary policy and global prudential policies; and from their UK affiliates to third‐party countries in a manner that depends on local prudential settings.     

WHAT CAUSES THE EFFICIENCY AND THE TECHNOLOGY GAP UNDER DIFFERENT OWNERSHIP STRUCTURES IN THE CHINESE BANKING INDUSTRY?

This paper estimates and compares the cost efficiency of the Chinese banking industry among different ownership types for the period 2003–2014, using the stochastic metafrontier model. We find that foreign banks have the lowest cost frontier, while state‐owned commercial banks undertake the least sophisticated technology. Moreover, the results of the upward trend in the technology gap ratio (TGR) and in metafrontier cost efficiency support that a more open financial market is able to enhance banking efficiency. As for the role of environmental conditions, off‐balance sheet items, non‐performing loans, and financial market structure significantly impact the TGRs of different bank types.

HOW DID STATE‐OWNED BANKS RESPOND TO PRIVATIZATION? EVIDENCE FROM THE INDIAN EXPERIMENT

ABSTRACT ** : The paper examines the response of banks to privatization. Using data on all state‐owned banks for the period 1990–2006, the findings indicate that fully state‐owned banks are significantly less profitable than partially privatized ones. The improvements in performance by partially privatized banks are, in fact, sustained after privatization. In addition, the analysis indicates that privatization improves profitability, efficiency and improves bank soundness, while lowering bank risk. While the improvement in bank risk is typically spread out over a much longer period, the progress in terms of profitability and economic efficiency typically occurs in the post‐privatization period.     

货币政策能否促进银行对小微企业信贷投放——基于宏观经济不确定视角的研究

本文研究在宏观经济不确定条件下,不同货币政策工具能否促进银行对小微企业信贷投放。首先,将货币政策引入考虑了宏观经济不确定性的银行资产组合模型中,论证货币政策、宏观经济不确定性与银行信贷资产配置的理论关系。然后利用我国181家银行2004—2018年的数据,检验在宏观经济不确定条件下,不同货币政策工具对银行小微企业信贷行为调控的作用效果。研究结果表明：宏观经济不确定性会抑制银行信贷行为。其中小微企业信贷占比较大的银行受到的影响更为显著。与数量型货币政策相比,价格型货币政策能够更显著地减轻不确定性对银行小微信贷的消极影响。其中银行同业拆借利率的调控效果最强。研究结论对于选择适宜的货币政策工具促进银行向小微企业信贷投放,化解经济不确定性对银行信贷行为的影响并助力小微企业发展等具有政策借鉴意义。     

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.
