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.     

Is there a tradeoff between bank competition and financial fragility?

We use a model of mean-shifting investment technologies to study the relationship between market structure, risk taking and social welfare in lending markets. Introduction of loan market competition is shown to reduce lending rates and to generate higher investments without increasing the equilibrium bankruptcy risk of borrowers. Hence, there need not be a tradeoff between lending market competition and financial fragility. Such a tradeoff may not emerge either when banks compete by conditioning interest rates on investment volumes irrespectively of whether credit rationing takes place or not.     

Predicting Prepayment and Default Risks of Unsecured Consumer Loans in Online Lending

Online lending provides a means of fast financing for borrowers based on their creditworthiness. However, borrowers may undermine this agreement due to early repayment or default, which are two major concerns for the platform and lenders, since both affect the profitability of a loan. While default risk is frequently focused on credit scoring literature, prepayment has received much less attention, despite a higher prepayment rate being observed in online lending when compared with default. This article uses multivariate logistic regression to predict the probability of both the underlying prepayment and default risks. Real consumer lending data of 140,605 unsecured loans provides evidence that these two events have their own distinct patterns. We consider systemic risk by incorporating macroeconomic factors in modeling and address the influence of economic conditions, which are lessons learnt from the last financial crisis. The out-of-sample validation has shown that both prepayment and default can be accurately predicted. This article highlights the necessity of regulations on prepayment given the fast growing online lending market.     

Complexity, concentration and contagion

This paper develops a network model of interbank lending in which unsecured claims, repo activity and shocks to the haircuts applied to collateral assume centre stage. We show how systemic liquidity crises of the kind associated with the interbank market collapse of 2007–2008 can arise within such a framework, with funding contagion spreading widely through the web of interlinkages. Our model illustrates how greater complexity and concentration in the financial network may amplify this fragility. The analysis suggests how a range of policy measures – including tougher liquidity regulation, macro-prudential policy, and surcharges for systemically important financial institutions – could make the financial system more resilient.     

Cross-border banking,bank market structures and market power: Theory and cross-country evidence

Patterns in cross-border banking have changed since the global financial crisis. This may affect domestic bank market structures and macroeconomic stability in the longer term. In this study, I theoretically and empirically analyze how different modes of cross-border banking impact bank concentration and market power. I use a two-country general equilibrium model with heterogeneous banks developed by DeBlas and Russ (2010a) to grasp the effect of cross-border lending and foreign direct investment in the banking sector on bank market structures. The model suggests that both cross-border lending and bank FDI mitigate concentration. Empirical evidence from a panel dataset of 18 OECD countries supports the theoretical predictions: higher volumes of bank FDI and of cross-border lending coincide with lower Herfindahl-indexes in bank credit markets.     

金融危机后欧美回购市场的发展及借鉴意义

受2008年全球金融危机和其后欧债危机的影响,欧美回购市场出现了一些新的趋势和特征,如短期融资渠道由无担保的信用拆借市场向有担保的回购市场转移,三方回购和自动交易系统交易占比稳步上升等。与欧美市场相比,我国回购市场起步较晚,在规模、交易后处理、抵押品管理以及交易工具等方面存在自身特点。文章对我国银行间回购市场的发展现状和不足进行了总结,并对照欧美回购市场发展的经验和教训,提出了改善我国银行间回购市场流动性、促进交易活跃度的建议。     

Central bank reserves and interbank market liquidity in the euro area

The market-oriented approach promoted by the European Central Bank in the design of its refinancing operations creates incentives to credit institutions to use actively the interbank market to manage their liquidity needs. In this context, we examine the ability of the overnight segment to guarantee the timely provision of unsecured funds to banks to smoothly absorb their liquidity shocks. This paper specifically focuses on the speed of reversion of transaction costs and available depth to their equilibrium levels in this market for overnight unsecured funds. The reported evidence points to time-varying liquidity adjustments and identifies liquidity, market activity and the institutional setting of the ECB’s refinancing operations as significant determinants of the observed resiliency regimes. Our analysis also shows how the speed of mean reversion of market liquidity, by affecting the level and the volatility of the overnight market rate, also affects the anchoring of the yield curve in the euro area.     

Across-the-Curve Credit Spread Indices

We design a novel across-the-curve credit spread index, AXI, a measure of the recent cost of wholesale unsecured debt funding for publicly listed US bank holding companies and commercial banks. AXI, a benchmark for bank lending and risk management, is the weighted average of credit spreads for unsecured debt instruments with maturities ranging from overnight to five years, with weights that reflect both transaction and issuance volumes. We provide illustrative output of the bond-based component of AXI. By widening coverage to include all corporate debt issuers, we also build a financial conditions index (FXI).     

In good times and in bad: Bank capital ratios and lending rates

This paper investigates the relationship between bank capital ratios and lending rates using data from 1998 to 2012 for 13 large banks accounting for 75% of total UK lending. We document a substantial change in the coefficient of the Tier 1 capital ratio in reduced-form regressions for secured household lending rates; the coefficient changes from positive pre-crisis to negative in crisis. Significant changes are also detected in the relationship for unsecured household and corporate lending. Such instability is difficult to reconcile with many well-established theories of financial intermediation but is consistent with the relatively recent theories of bank portfolio decisions emphasising cyclical variation in bank leverage and risk-appetite.     

Why do financial systems differ? History matters

We describe a dynamic model of financial intermediation in which fundamental characteristics of the economy imply a unique equilibrium path of bank and financial market lending. Yet we also show that economies whose fundamental characteristics have converged may continue to have very different financial structures. Because setting up financial markets is costly in our model, economies that emphasize bank lending are more likely to continue doing so in the future, all else equal.     

The Neighborhood Distribution of Subprime Mortgage Lending

Subprime lending in the residential mortgage market, characterized by relatively high credit risk and interest rates or fees, has developed over the past decade into a prominent segment of the market (Temkin, 2000). Recent research indicates that there is geographical concentration of subprime mortgages in Census tracts where there are high concentrations of low-income and minority households. The growth in subprime lending represents an expansion in the supply of mortgage credit among households who do not meet prime market underwriting standards. Nonetheless, its apparent concentration in minority and lower income neighborhoods has generated concerns that these households may not be obtaining equal opportunity in the prime mortgage market. Such lending may undermine revitalization to the extent that it is associated with so-called predatory practices.     

Deposit insurance and credit union lending

We exploit an exogenous change in the coverage of insured deposits following the passage of the Emergency Economic Stabilization Act (2008) to investigate the impact of deposit insurance on the volume, composition and quality of credit union lending. Using a difference-in-difference approach, we find changes in the volume, composition and riskiness of credit union lending. Specifically, we find that affected credit unions increase total and unsecured lending, leading to a decline in loan quality. Overall, our results suggest that an increase in the maximum coverage of insured deposits induces credit unions to lend more at the expense of loan quality.     

Integration of Lending and Underwriting: Implications of Scope Economies

Informational scope economies provide a cost advantage to universal banks offering “one‐stop shopping” for lending and underwriting that enables them to “lock in” their clients' subsequent business. This market power reduces universal banks' incentive, relative to that of specialized investment banks, to apply costly underwriting efforts; consequently, universal banks are less successful in selling their clients' securities. Our results suggest that an integrated financial services market is less innovative than one with specialized intermediaries. Our analysis also identifies economy, intermediary, and firm characteristics that motivate either the integration or segmentation of bank lending and underwriting.     

Bank competition and financing efficiency under asymmetric information

We consider a setting in which an entrepreneur seeks bank financing, and the project type is her private information. Different from existing theories featuring information asymmetry, and consistent with empirical findings, our model predicts: greater bank competition leads to increased bank lending as interest rates fall, leading to lower quality loans. The relationship between market power and financing efficiency is hill-shaped. An intermediate level of market power is desirable, as it can mitigate inefficiencies arising due to cross-subsidization among borrowers in a pooling equilibrium. Interest rate controls may achieve efficiency, but the specific policy depends on the bank market structure.     

Access policy and money market segmentation

Deviations between interest rates paid in the Swiss franc unsecured money market and the respective Libor rate are analysed for a period spanning the financial crisis. First, banks that have access to sources of secured central bank and interbank funding pay less than other banks. Second, foreign banks (not chartered in Switzerland) pay more than domestic banks. Third, both lines of segmentation are economically relevant but limited due to open access to sources of secured funding. Thus, access policy matters for monetary policy implementation and financial stability.     

Transparency in the Mortgage Market

This paper studies the impact of transparency in the mortgage market on the underlying real estate market. We show that geographic transparency in the secondary mortgage market, which implies geographic risk based pricing in the primary market, can limit risk-sharing and make house prices more volatile. Ex ante, regions prefer opaque markets to enable insurance opportunities. We discuss the implications for risk based pricing and house price volatility more generally. In addition, we investigate the specific conditions under which competitive lenders would optimally choose to provide opaque lending, thus reducing volatility in the real estate market. We show that in general the opaque competitive equilibrium is not stable, and lenders have incentive to switch to transparent lending if one of the geographic regions has experienced a negative income shock. We propose market and regulatory mechanisms that make the opaque competitive equilibrium stable and insurance opportunities possible.     

Unsecured credit markets are not insurance markets

We study the extent to which unsecured credit markets have altered the transmission of increased income risk to consumption variability over the past several decades. We find that unsecured credit markets pass through increased income risk to consumption, irrespective of bankruptcy policy and the information possessed by lenders. If risk sharing has indeed improved over this period, the reasons do not therefore lie in the unsecured credit market.     

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.     

Banks' consumer lending reaction to fintech and bigtech credit emergence in the context of soft versus hard credit information processing

Access to credit information and the ability to process this information effectively determine the conditions of competition in the credit market. Traditionally, local banks have had an advantage in relationship lending (based on soft credit information), whereas foreign banks are considered to base on hard credit information. With the advent of financial technology (or “fintech”) companies (or “fintechs”) and giant technology (or “bigtech”) companies (or “bigtechs”) providing alternative credit, the conditions of competition in the credit market have changed. In this empirical study, we shed light on the nature of the information advantages fintech and bigtech companies have compared to banks and how alternative lenders use them. We analyze competition in the consumer lending segment between banks and fintechs as well as bigtechs providing alternative lending. We used a database combining bank-level characteristics and country-level proxies for 72 countries from 2013 to 2018. We find that in developed markets, the relationships between fintech and bigtech credit providers and banks are similar and competitive in nature. However, banks' consumer lending grows simultaneously with fintech credit market development in emerging economies, but decreases in the aftermath of the emergence of bigtech credit. Fintech credit seems to penetrate market segments not serviced by banks; thus, it plays a complementary role, however only in emerging economies. Bigtech companies compete even more with banks and push some banking offers out of the market, both in emerging and developed economies. Furthermore, we show that domestic and privately-owned banks are more negatively affected by competition from technology-based lending, particularly bigtech, than foreign banks. Thus, bigtech lending may be treated as a serious competition for banks' relationship lending based on soft credit information processing, traditionally provisioned by local banks.     

Competition,transmission and bank pricing policies: Evidence from Belgian loan and deposit markets

This paper addresses the pass-through from market interest rates to retail bank interest rates. The paper advocates a heterogeneous approach and applies it to the Belgian banking market. A substantial proportion of the heterogeneity in bank pricing policies can be explained by the bank lending channel and the relative market power hypothesis. The results also suggest that the long-term pass-through is typically less than one-for-one, rejecting the completeness hypothesis. While there is no convincing evidence for asymmetry in retail rates, large deviations from equilibrium mark-ups are faster reduced than small deviations. Overall, conditions for corporate loans are more competitive compared to consumer loans. Demand and savings deposits have, by far, the most rigid prices.
