Consolidation in banking and the lending channel of monetary transmission: Evidence from Asia and Latin America

This paper examines the relationship between increased consolidation in banking and monetary policy transmission in eighteen Asian and Latin American economies, using bank-level data from 1996 to 2006. Our results provide consistent evidence that as concentration in banking increases, the bank lending channel is weakened, leading the monetary policy transmission mechanism to be less effective. We also investigate how this relationship between concentration and the strength of the lending channel depends on bank-specific characteristics. Using bank-level balance sheet and income statement data allows us, first, to better identify the effects of banking consolidation on the supply-side bank lending channel from those of the demand-side interest rate channel, and second, to test for any systematic differences in the impact of consolidation on monetary policy transmission across banks of different size and financial strength. We also discuss potential explanations for and policy implications of the main findings of this paper.     

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.     

Monetary policy,bank competition and regional credit cycles: Evidence from a quasi-natural experiment

This paper examines how competition in the banking sector affects the transmission of monetary policy and the variation of credit expansion across regions in the United States. Using the U.S. branching deregulation between 1994 to 2008 as an exogenous change in banks’ competition, we analyze how bank competition affects monetary policy transmission through the bank lending channel. The results show that competition strengthens the impact of monetary policy on bank loan supply. We then show that states with a more deregulated banking sector were more affected by monetary conditions in the years leading to the Great Recession. Specifically, the effect of loose monetary conditions on the expansion of households’ debt was stronger in states that had fewer bank branching restrictions. The results suggest that variations in the level of bank competition may have amplified regional asymmetries in the years leading to the Great Recession.     

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.     

Competition and Concentration in the New European Banking Landscape

This paper measures the degree of concentration and competition in the enlarged European Union (EU) banking environment over the period 1998–2002. In the empirical part we opt for a methodology as proposed by Panzar and Rosse based on a non‐structural estimation of market competition. Our results suggest that European banks were operating under conditions of monopolistic competition and that bank interest revenues in the 10 new EU member states was earned under conditions of higher competition than those that existed in the old EU banking countries. The opposite result was observed for total operating revenues. Smaller banks earn interest income in a less competitive environment than larger banks, while the opposite is observed for total revenues.     

Sovereign risk and the bank lending channel in Europe

The main purpose of this article is to analyze how sovereign risk influences the loan supply reaction of banks to monetary policy through the bank lending channel. Additionally, we aim to test whether this reaction differs in easy and tight monetary regimes. Using a sample of 3125 banks from the euro zone between 1999 and 2012, we find that sovereign risk plays an important role in determining loan supply from banks during tight monetary regimes. Banks in higher sovereign risk countries reduce lending more during tight regimes. However, we find little evidence to support any relationship between sovereign risk and loan supply reaction to monetary policy expansions. These results are very interesting for the way monetary policy is conducted in Europe. Banking union, banking system strength, and the budget control of governments would be necessary measures to reduce the heterogeneous transmission of the monetary policy in the euro zone.     

The effect of banking market structure on the lending channel: Evidence from emerging markets

This paper analyses the extent to which the level of bank competition influences monetary policy transmission. Using a large panel dataset of 978 banks from 55 countries, and employing the Lerner index model as a measure of market structure, our results show that an increase in banking sector competition weakens the effectiveness of monetary policy on bank lending. The findings are robust to a broad array of sensitivity checks including control of alternative measurements of the Lerner index, different samples and different methodological specifications. By extension, these results have important policy implications for regulators in assessing the effectiveness of monetary policy transmission mechanisms.     

Does the expansion of regional cross-border banks affect competition in Africa? Indirect evidence

This article investigates how bank competition has evolved in Africa following the recent penetration and expansion of regional cross-border banks over the past decade. We examine changes in competition in the banking industry of seven African countries highly affected by this recent phenomenon. The evolution of competition is evaluated through three different non-structural measures of competition (Lerner index, Panzar–Rosse model, and Boone indicator). With the exception of results from the Lerner index, our findings show an intensification of competition since the mid-2000s. This period corresponds to the rapid expansion of regional cross-border banks in the zone, indicating that this expansion has promoted competition in banking sectors in Africa.     

International monetary policy transmission through banks in small open economies

This paper studies the international transmission of monetary policy through banks in small open economies using the examples of Switzerland and Canada. We assess the inward transmission of foreign monetary policy for Switzerland and the outward transmission of domestic monetary policy for Canada. In both country cases, we focus on the international bank lending and the international portfolio channel, which make opposing predictions about how monetary policy transmits internationally through banks. Our results on the inward transmission of foreign monetary policy through banks in Switzerland are consistent with a role for the international portfolio channel, but we find no evidence for the traditional international bank lending channel. The results on the outward transmission of domestic monetary policy in Canada suggest that foreign lending by Canadian banks is affected through both channels, which work as predicted and largely balance each other.     

Banking deregulation,macroeconomic dynamics and monetary policy

We assess the effects of increased bank competition on macroeconomic and lending dynamics and on the transmission of monetary policy. Applying panel local projections to state-level data, we, in a first step, investigate the dynamic effects of fiercer bank competition induced by deregulation allowing geographical expansion of banks across state borders in the 1980s and early-1990s. We allow for possible adjustments before the new laws became effective due to potential anticipation effects. Our findings suggest that these events were anticipated and that they temporarily increased economic activity as well as business and consumer lending. We also find a permanent increase in real estate lending and house prices. In a second step, we show that the impact of monetary policy on economic activity, house prices and lending tended to become stronger after interstate banking deregulation.     

The bank lending channel in the Malaysian Islamic and conventional banking system

This paper examines the bank lending channel of monetary transmission in Malaysia, a country with a dual banking system including both Islamic and conventional banks, over the period 1994: 01-2015:06. A two-regime threshold vector autoregression (TVAR) model is estimated to take into account possible nonlinearities in the relationship between bank lending and monetary policy under different economic conditions. The results indicate that Islamic credit is less responsive than conventional credit to interest rate shocks in both the high and low growth regimes; however, the sub-sample estimation shows that its response has increased in more recent years becoming quite similar to that of conventional credit. Moreover, the relative importance of Islamic credit shocks in driving output growth is notable in the low growth regime, their effects being positive. These findings can be interpreted in terms of the distinctive features of Islamic banks.     

The international transmission of monetary policy

This paper presents the novel results from an internationally coordinated project by the International Banking Research Network (IBRN) on the cross-border transmission of conventional and unconventional monetary policy through banks. Teams from seventeen countries use confidential micro-banking data for the years 2000 through 2015 to explore the international transmission of monetary policies of the United States, euro area, Japan, and United Kingdom. Two other studies use international data with different degrees of granularity. International spillovers into lending to the private sector do occur, especially for US policies, and bank-specific heterogeneity influences the magnitudes of transmission. The effects are supportive of the international bank lending channel and the portfolio channel of monetary policy transmission. They also show that the frictions that banks face matter; in particular, foreign currency funding and hedging considerations can be a key source of heterogeneity. The forms of bank balance sheet heterogeneity that differentiate spillovers across banks are not uniform across countries. International spillovers into lending can be large for some banks, even while the average international spillovers of policies into nonbank lending generally are not large.     

Are Competitive Banking Systems More Stable?

Using the Panzar and Rosse H-statistic as a measure of competition in 45 countries, we find that more competitive banking systems are less prone to experience a systemic crisis and exhibit increased time to crisis. This result holds even when we control for banking system concentration, which is associated with higher probability of a crisis and shorter time to crisis. Our results indicate that competition and concentration capture different characteristics of banking systems, meaning that concentration is an inappropriate proxy for competition. The findings suggest that policies promoting competition among banks, if well executed, have the potential to improve systemic stability.     

The Impact of Foreign Banks on Monetary Policy Transmission During the Global Financial Crisis of 2008–2009: Evidence from Korea

This article examines the impact of foreign banks on the monetary policy transmission mechanism in the Korean economy during the period from 2000 to 2012, with a specific focus on the lending behavior of banks with different types of ownership. Using bank-level panel data of the banking system in Korea, we present consistent evidence on the buffering impact that the foreign banks, especially foreign bank branches including US bank branches, on the effectiveness of the monetary policy transmission mechanism in Korea from the bank-lending channel perspective during the global financial crisis of 2008–2009.     

The relationship between banking market competition and risk-taking: Do size and capitalization matter?

This paper addresses the effects of bank competition on the risk-taking behaviors of banks in 10 Latin American countries between 2003 and 2008. We conduct our empirical approach in two steps. First, we estimate the Boone indicator, which is a measure of competition. We then regress this measure and other explanatory variables on the banking “stability inefficiency” derived simultaneously from the estimation of a stability stochastic frontier. Unlike previous findings, this paper concludes that competition affects risk-taking behavior in a non-linear way as both high and low competition levels enhance financial stability, while we find the opposite effect for average competition. In addition, bank size and capitalization are essential factors in explaining this relationship. On the one hand, the larger a bank is, the more it benefits from competition. On the other hand, a greater capital ratio is advantageous for banks that operate in collusive markets, while capitalization only enhances the stability of larger banks under high and average competition. These results are of extreme importance when considering bank regulations, especially in light of the recent turmoil in the global financial markets.     

Assessing competition in the banking industry: A multi-product approach

This paper investigates the competitive aspects of multi-product banking operations. Extending Panzar and Rosse’s (1987) model to the case of a multi-product banking firm, we show that higher economies of scope in multi-product banking are associated with lower Panzar–Rosse measures of competition in the banking sector. To test this empirical implication and determine the impact of multi-production on market power, we use a new dataset on the Brazilian banking industry. Consistent with our theoretical prediction, we find that banks that offer classic banking products (i.e., loans and credit cards) and other banking products (i.e., brokerage services, insurance and capitalization bonds) have substantially higher market power than banks that offer only classic products. These results suggest a positive bias in the traditional estimates of competition in which multi-output actions are not considered.     

Monetary transmission during low interest rate environment in a dual banking system: evidence from Malaysia

This study aims to determine the role of bank loans in the transmission of monetary policy in an environment of low interest rate in the context of a dual banking system in Malaysia. By adopting a balanced panel data approach applied on data covering the period from 2000 to 2011, the study finds that changes in the monetary policy have no significant impact on the level of financing extended by the Islamic and conventional banks. However, bank-specific factors, namely size and liquidity play an important role in influencing the lending behaviour of both the Islamic and conventional banks, whereas capitalization is relevant only for the Islamic banks. Findings of the study provide important input for effective monetary policy implementation in countries with increasing presence of the Islamic banks.     

Monetary policy and bank lending:: Evidence from German banking groups

This paper analyses the impact of monetary shocks on bank lending in Germany. We follow a cross-sectoral approach by looking at six different banking groups. In general, smaller banks hold a larger buffer of liquid assets which they can use to offset monetary shocks. In addition, the response of bank lending after a monetary contraction is very different across banking sectors. Lending by the credit co-operatives, which are on average the smallest banks, declines most, whereas big banks are able to shield their loans portfolio against monetary shocks. Overall, our results provide support for the existence of a bank lending channel.     

Firm balance sheets and monetary policy transmission

The functioning of internal capital markets in financial conglomerates facilitates a novel identification strategy of the balance sheet channel of monetary policy. We look at small subsidiary banks that are affiliated with the same holding company but operate in different geographical areas. These banks face the same marginal cost of funds due to internal capital markets, but face different borrowers as they concentrate their lending with small local businesses. Exploring cross-sectional variation in local economic conditions across these subsidiaries, we investigate whether borrower creditworthiness influences the response of bank lending to monetary policy. Our results are consistent with a demand-driven transmission mechanism that works through firm balance sheets and is independent from the bank lending channel.     

The Bank Lending Channel Revisited

A central proposition in research on the role of banks in the transmission mechanism is that monetary policy imparts a direct impact on deposits and that deposits act as the driving force of bank lending. This paper argues that the emphasis on policy‐induced changes in deposits is misplaced. A reformulation of the bank lending channel is proposed that works primarily through the impact of monetary policy on banks’ balance sheet strength and risk perception. Such a recasting implies, contrary to conventional wisdom, that greater reliance on market‐based funding enhances the importance of the channel.
