Interbank relationship lending revisited: Are the funds available at a similar price?

Under the market discipline hypothesis, monitoring by interbank lenders may induce changes in either the price or availability of new interbank funds to borrower banks. However, the presence of interbank relationship lending has been evaluated based on the availability of funds only—disregarding their price. We revisit relationship lending in unsecured interbank lending markets by simultaneously evaluating the availability and price of funds. We calculate the survival ratio of networks containing the price of daily interbank lending in Colombia from 2014 to 2020. Under this framework, an interbank relation survives from one day to the next if the funds are available at a price that does not increase too much; that is, either a halt in interbank funding or a sizeable increase in the price of interbank funding mark a break in the relation between two banks. We find that about 38 percent of relations in the Colombian unsecured interbank lending market survive from one day to the next. Therefore, from a comprehensive market discipline perspective, we find evidence of interbank relationship lending in Colombia.     

Noncore Bank Liabilities and Financial Vulnerability

A lending boom is reflected in the composition of bank liabilities when traditional retail deposits (core liabilities) cannot keep pace with asset growth and banks turn to other funding sources (noncore liabilities) to finance their lending. We formulate a model of credit supply as the flip side of a credit risk model where a large stock of noncore liabilities serves as an indicator of the erosion of risk premiums and hence of vulnerability to a crisis. We find supporting empirical evidence in a panel probit study of emerging and developing economies.     

How do global banks scramble for liquidity? Evidence from the asset-backed commercial paper freeze of 2007

We investigate how banks scrambled for liquidity following the asset-backed commercial paper (ABCP) market freeze of August 2007 and its implications for corporate borrowing. Commercial banks in the United States raised dollar deposits and took advances from Federal Home Loan Banks (FHLBs), while foreign banks had limited access to such alternative dollar funding. Relative to before the ABCP freeze and relative to their non-dollar lending, foreign banks with ABCP exposure charged higher interest rates to corporations for dollar-denominated syndicated loans. The results point to a funding risk manifesting as currency shortages for banks engaged in maturity transformation in foreign countries.     

Relationship Banking, Fragility, and the Asset-Liability Matching Problem

We address a fundamental question in relationship banking: whydo banks that make relationship loans finance themselves primarilywith core deposits and when would it be optimal to finance suchloans with purchased money? We show that not only are relationshiploans informationally opaque and illiquid, but they also requirethe relationship between the bank and the borrower to endurein order for the bank to add value. However, the informationalopacity of relationship loans gives rise to endogenous withdrawalrisk that makes the bank fragile. Core deposits are an attractivefunding source for such loans because the bank provides liquidityservices to core depositors and this diminishes the likelihoodof premature deposit withdrawal, thereby facilitating the continuityof relationship loans. That is, we show that banks will wishto match the highest value-added liabilities with the highestvalue-added loans and that doing so simultaneously minimizesthe bank's fragility owing to withdrawal risk and maximizesthe value the bank adds in relationship lending. We also examinethe impact of interbank competition on the bank's asset-liabilitymatching and extract numerous testable predictions.     

Mapping the UK interbank system

We present new evidence on the structure of interbank connections across key markets: derivatives, marketable securities, repo, unsecured lending and secured lending. Taken together, these markets comprise two networks: a network of interbank exposures and a network of interbank funding. Network structure varies across and within these two networks, for reasons related to markets’ different economic functions. Credit risk and liquidity risk therefore propagate in the interbank system through different network structures. We discuss the implications for financial stability.     

Balancing liquidity and returns through interbank markets: Endogenous interest rates and network structures

In this article, we develop a model of interbank lending based on liquidity and return on equity considerations of homogeneous banks. We derive the reservation prices of interbank lending and its properties before exploring how, because of an idiosyncratic liquidity shock, banks engage in bilateral lending to form an interbank network. We establish that the resulting networks exhibit realistic properties, including a core-periphery structure. Banks in the core and the periphery of this network differ not only in the amounts of interbank lending and borrowing but also in the interest rates applied to their transactions.     

Liquidity creation and funding ability during the interbank lending crunch

This study examines the portfolio response of US banks to the interbank lending collapse during the global financial crisis. The paper documents that a bank's response to the collapse of interbank markets is related to whether or not the bank was a net borrower or lender of funds. In particular, we find that typical borrowers had lower loan growth than typical lenders, but that the crisis did not differentially affect borrowers and lenders with respect to loan growth. However, borrowing and lending banks were differentially affected by the crisis in terms of their liquid asset growth. The typical borrowers reduced their liquid asset growth relative to lending banks during the crisis. We interpret this finding as saying that borrowing banks had to reduce their risky asset holdings because access to interbank funds had been reduced. The paper presents analogous analyses of the possible differential response of borrowers and lenders to changes in counterparty risk and lending through the Fed's TAF facility.     

Credit risk interconnectedness: What does the market really know?

We analyze the relation between market-based credit risk interconnectedness among banks during the crisis and the associated balance sheet linkages via funding and securities holdings. For identification, we use a proprietary dataset that has the funding positions of banks at the bank-to-bank level for 2006–2013 in conjunction with investments of banks at the security level and the credit register from Germany. We find asymmetries both cross-sectionally and over time: when banks face difficulties to raise funding, the interbank lending affects market-based bank interconnectedness. Moreover, banks with investments in securities related to troubled classes have a higher credit risk interconnectedness. Overall, our results suggest that market-based measures of interdependence can serve well as risk monitoring tools in the absence of disaggregated high-frequency bank fundamental data.     

Dissecting Foreign Bank Lending Behavior During the 2008–2009 Crisis

This paper analyzes the lending behavior of foreign‐owned banks during the recent global crisis. Using bank‐level panel data for 51 countries, the paper explores the role of affiliate and parent financial characteristics, host location, as well as the impact of parent geographic origin and reach on foreign banks’ credit growth. Overall, the analysis finds robust evidence that foreign banks curtailed the growth of credit relative to other banks, independent of the host region in which they operate. Banks from the United States reduced loan growth less than other parent banks. Neither the global nor regional reach of parent banks influenced the lending growth of foreign affiliates. Parent capitalization and not parent funding explained the behavior of foreign bank credit growth during the global crisis. However, funding did affect the lending behavior of domestic and foreign banks in host countries, with those relying more heavily on deposits suffering a smaller decline in bank lending. Although not the focus of the paper, we also find that government‐owned banks played a countercyclical role in all regions.     

Does Interbank Borrowing Reduce Bank Risk?

In this paper we investigate whether banks that borrow from other banks have lower risk levels. We concentrate on a large sample of Central and Eastern European banks that allows us to explore the impact of interbank lending when exposures are long term and interbank borrowers are small banks. The results of the empirical analysis generally confirm the hypothesis that long-term interbank exposures result in lower risk of the borrowing banks.     

Interbank contagion risk in China under an ABM approach for network formation

This paper uses an agent-based model to construct an interbank network for the Chinese interbank market using a sample of 299 commercial banks from 2014 to 2019. We analyze the importance and vulnerability of banks using the DebtRank algorithm. Our results show that the Chinese interbank market bears a certain level of systemic risk, especially among lower-tiered banks. The results also show a bank is more vulnerable if it has a higher interbank lending ratio and greater financial connectivity. Meanwhile, a bank is more influential if it has a larger net worth and greater financial connectivity.     

Do public banks have a competitive advantage?

Public banks are often blamed to possess an unfair competitive advantage in the form of lower funding costs due to a state guarantee on their deposits. However, public and private banks tend to differ not only in their funding costs, but also in the way they deal with borrowers in financial distress. The model presented in this paper shows that if banks differ in these two characteristics, a separation of borrowers may result, with public banks lending to risky firms and private banks lending to safe firms. This separation can explain differences in the lending behavior and performance of public and private banks as observed in the market. Interestingly, the separation may persist even when funding costs are equal, implying that an abolition of state guarantees will not necessarily lead to identical performance of the two types of banks.     

Which banks smooth and at what price?

By adjusting lending, banks can smooth the macroeconomic impact of deposit fluctuations. This may, however, lead to extended periods of disproportionately high lending relative to deposit intake and, under certain conditions, to the accumulation of risk in the banking system. Using bank-level data for 8477 banks in 129 countries for the period from 1992 to 2015, we examine how banks' market power and other characteristics may contribute to smoothing or amplification of shocks and the accumulation of risk. We find that the higher their market power the lower is the growth rate of lending relative to deposits. As a result, in periods of falling deposits higher market power for the average bank is associated with a greater fall in lending, consistent with amplification of adverse effects during relatively bad times. Strikingly, at very high levels of market power, there is a threshold past which the effect of market power on the growth rate of lending relative to deposits turns positive so that “superpower” banks may contribute to the smoothing of adverse effects when deposits are falling. In periods of rising deposits, however, such banks are more likely to lead to amplification and accumulation of risk in the economy.     

Liquidity crisis,relationship lending and corporate finance

This paper investigates the consequences of the liquidity shocks in wholesale funding markets during the 2007–2009 financial crisis on bank lending and corporate financing. We show that banks that relied more heavily on wholesale funding contracted lending more severely than banks that relied more on insured deposits. We then examine the effects of loan contraction on the financial positions of publicly traded firms. We find that both during and after the crisis, the change in leverage of bank-dependent firms is less than that of firms with access to public debt markets. In addition, bank-dependent firms rely more on cash than net equity issuance to finance operations. We also find that firms with established bank lending relationships weather the crisis better. Such firms are able to attain higher levels of leverage during the crisis, add to their cash holdings, secure new bank credit, and achieve higher profitability as a result.     

Correlated bank runs,interbank markets and reserve requirements

This article extends the application of global games of Goldstein and Pauzner (2005) in the banking model of Diamond and Dybvig (1983) to account for correlation in the quality of banks’ long term investment, when banks are linked through cross deposits and there is a central bank. The goal is to study how these elements affect the deposit contract that banks offer to depositors and the ex ante probability of a bank run. We show that the coexistence of a central bank, which determines banks’ reserve requirements, and an interbank market, which redistributes reserves, leads to a smaller probability of a bank run and to fewer inefficient bank runs, relative to the case with no central bank and no interbank market. By adequately choosing the level of reserves to store, the central bank can improve the equilibrium outcome and allow banks to offer a higher interim payment to depositors, relative to the situation with no cross deposits.     

Bank-to-bank lending channel and the transmission of bank liquidity shocks: Evidence from France

Good liquidity is essential for the banking system to function properly and supply credit to the real sector. However, several banks all over the world face large shocks to their liquidity supply due to numerous factors. This study contributes to the literature on the transmission of liquidity shocks by investigating the bank-to-bank lending behavior of French banks during the global financial crisis (2008 and 2009). In addition, we examine the factors strongly influencing the liquidity of the interbank deposits market. First, using a fixed-effects model on a sample of 85 French banks for the period from 2005 to 2010, we find that the deposits channel plays an important role in the transmission of liquidity shocks across the banking system. Second, we use difference-in-difference methodology to study the effects of liquidity shock on bank lending. Our results show that French banks reduced their bank-to-bank lending significantly during the financial crisis period. Moreover, our results suggest that the reduction could have been due to deposit activities.     

Deposits and relationship lending

We empirically examine whether access to deposits with inelasticrates (core deposits) permits a bank to make contractual agreementswith borrowers that are infeasible if the bank must pay marketrates for funds. Such access insulates a bank's costs of fundsfrom exogenous shocks, allowing it to insulate its borrowersagainst exogenous credit shocks. We find that, controlling forloan market competition, banks funded more heavily with coredeposits provide more loan rate smoothing in response to exogenouschanges in aggregate credit risk. Thus we provide evidence fora novel channel linking bank liabilities to relationship lending.     

Cyclicality of SME lending and government involvement in banks

Recent regulatory efforts aim at lowering the cyclicality of bank lending because of its potentially detrimental effects on financial stability and the real economy. We investigate the cyclicality of SME lending of local banks with versus without a public mandate, controlling for location, size, loan maturity, capitalization, funding structure, liquidity, profitability, and credit demand-side factors. The public mandate is set by local governments and stipulates a sustainable provision of financial services to local customers and a deviation from strict profit maximization. We find that banks with a public mandate are 25% less cyclical than other local banks. The result is credit supply-side driven and especially strong for public mandate banks with high liquidity and stable deposit funding. Our findings have implications for the bank structure, financial stability and the finance-growth nexus in a local context.     

Explaining breakdowns in interbank lending: A bilateral bargaining model

The paper provides a simple model for interbank loans. Since interbank trades are usually over-the-counter transactions, we use a bilateral bargaining model and apply the Nash bargaining solution. We determine the threat points and the bargaining frontier of debtor and creditor banks. We ask under which conditions interbank lending will break down.     

The behavior of consumer loan rates during the 1990 credit slowdown

This study re-examines the 1990 credit slowdown by investigating the loan pricing behavior of commercial banks. We find strong evidence that large, undercapitalized banks contributed to the credit slowdown by charging consumers a higher-than-average loan rate relative to better-capitalized institutions. This disparity in lending exists even after accounting for bank funding costs. Thus, we argue that there was a lending slowdown that occurred among large, undercapitalized banks. The reluctance to lend among undercapitalized banks is at least suggestive of behavior that is consistent with a credit crunch.
