Banks' option to lend,interest rate sensitivity,and credit availability

Interest rate risk is a major concern for banks because of the nominal nature of their assets and the asset-liability maturity mismatch. This paper proposes a new way to derive a bank's interest rate sensitivity, by examining separately the effects of interest rate changes on existing loans(loans-in-place) and potential loans (loans-in-process). A potential loan is shown to be equivalent to an American option to lend, and is valued using option theory. An increase in interest rates generally has a negative effect on existing loans. However, if both deposit and lending rates rise by the same amount, the value of a potential loan generally increases. Hence a bank's lending slack (or ratio of loans-in-process to loans-in-place) will determine its overall interest rate risk. Empirical evidence indicates that low-slack banks indeed have significantly more interest rate risk than high-slack banks. The model also makes predictions regarding the effect of deposit and lending rate parameters on bank credit availability. Empirical tests with quarterly data are generally supportive of these predictions. This revised version was published online in June 2006 with corrections to the Cover Date.     

Corporate social responsibility,credit rating,and private debt contracting: new evidence from syndicated loan market

We examine the impact of corporate social responsibility (CSR) activities on loan spreads of syndicated bank loans, with a particular interest in how CSR and credit ratings are interrelated as a joint determinant of loan spreads. Focusing on private debt contracts, we show that both CSR strengths and concerns are related to their loan spreads. CSR strengths work to lower firm risk, hence reducing the loan spread, whereas CSR concerns increase firm risk, thus increasing the loan spread. Once we include detailed credit rating information in the models, however, CSR concerns lose significance, but CSR strengths remain significantly related to the loan spread. We also find that both CSR strengths and CSR concerns are related to loan spread for non-rated firms, but the CSR concern effect is stronger than the CSR strength effect for these firms. A further test shows that firm risk measured by stock return volatility plays as a direct channel through which a firm’s CSR activities affect loan spreads, whose result lends further support to our main results. Overall, our results provide strong evidence that CSR matters to the pricing of loan contracts beyond credit rating information and the results remain robust to the possible firm size effect and the endogeneity issues.     

The impact of loan prepayment risk and deposit withdrawal risk on the optimal intermediation margin

Numerous studies have analyzed how a bank's intermediation margin varies with respect to such factors as credit quality, funding risk, bank capital, deposit insurance and other factors. However, these studies ignore the potential that loans tend to prepay if interest rates decline and deposits tend to be withdrawn if interest rates rise. Taking this very fundamental fact into account, we derive optimal loan rates and deposit rates when the bank is subject to loan prepayments and deposit withdrawals. Among other things, we find that greater volatility of interest rates tends to increase the margin. The strength of the correlation between the level of interest rates and the propensity to prepay loans (withdraw deposits) also plays an interesting role.     

Credit unions vs. commercial banks,who takes more risk?

A unique feature of the financial services industry is that both shareholder-owned banks and member-owned credit unions coexist and compete against each other. In this study, we investigate two research questions. First, we compare risk-taking by banks and credit unions, with an additional consideration as to how regulatory oversight (state or federal) relates to such risk-taking. Second, we examine how competition affects the difference in risk-taking between these two types of financial institutions. To answer both questions, we rely on a matched sample (by loan type, size, and county) of commercial banks and credit unions, covering the period between 2010 and 2017. We use three empirical proxies for risk-taking, the Z-score, measuring an institution’s insolvency risk, as well as the ratios of non-performing loans to total loans and loan charge-offs to total loans, measuring the credit risk. Our results suggest that banks tend to engage in more risk-taking than credit unions; however, state regulatory oversight reduces the risk-taking gap, especially in terms of the Z-score. We further find that competition induces different risk-taking behaviors in banks and credit unions. Our results are robust to several alternative specifications.     

Competition,financial innovation and commercial bank loan portfolios

I examine how US commercial bank loan portfolios change in response to the rise of securitization markets and banking market deregulations over 1976–2003. Banks increasingly tilt their portfolios toward real-estate-backed loans. However, there are significant differences across banks. Larger banks and younger banks disproportionately shift their lending toward real-estate-backed loans, particularly commercial real-estate-backed loans, whereas smaller banks and older banks maintain greater shares of their loan portfolios in commercial and personal loans. When larger banks make more real-estate-backed loans, they charge lower interest rates, consistent with these banks lowering the costs of lending and expanding credit for borrowers. In contrast, smaller banks charge higher interest rates, consistent with these banks restricting lending to a select group of borrowers.     

Lender Automation and Racial Disparities in Credit Access

Process automation reduces racial disparities in credit access by enabling smaller loans, broadening banks' geographic reach, and removing human biases from decision making. We document these findings in the context of the Paycheck Protection Program (PPP), where private lenders faced no credit risk but decided which firms to serve. Black-owned firms obtained PPP loans primarily from automated fintech lenders, especially in areas with high racial animus. After traditional banks automated their loan processing procedures, their PPP lending to Black-owned firms increased. Our findings cannot be fully explained by racial differences in loan application behaviors, preexisting banking relationships, firm performance, or fraud rates.     

Regional redistribution through SBA guaranteed loan programs

We document and quantify a new implicit transfer mechanism in the SBA 7(a) loan program that redistributes funds between US states. We use SBA 7(a) loan data in conjunction with Dealscan private corporate loan data to show that SBA 7(a) loan interest rates are much less responsive to predicted local loan default risk compared to private corporate loans. This redistributes funds from states with low default risk to states with high default risk. These transfers are positively correlated with the severity of local economic shocks during the Great Recession and the COVID-19 Recession. Therefore, even though it was unintended, the interest rates on SBA 7(a) loans acted as an automatic stabilizer mitigating regional economic shocks.     

Basel III capital buffers and Canadian credit unions lending: Impact of the credit cycle and the business cycle

We take advantage of the long-standing regulation of the risk-based capital and the leverage ratio in Canada to provide empirical evidence on the relation between the credit unions' capital buffers and loans to members. Based on a unique sample of the 100 Canadian largest credit unions from 1996 to 2014, we find that both the risk-based capital buffer and the leverage buffer are positively related to changes in loans and loan growth. However, changes in these two types of buffers are negatively related to changes in the loans to assets ratios. This finding suggests that to adjust their capital buffers, Canadian credit unions curtail their loans and underscores the importance of the Basel III conservation and the countercyclical buffer requirements in fostering credit. Further, we show that the risk-based capital buffer is positively related to the credit cycle. However, a mechanical application of the rule based on the credit-to-gross domestic product (GDP) gap to activate the countercyclical buffer, would have misguided Canadian credit unions.     

汇率敏感性会影响企业贷款利率吗？——基于中国上市公司的分析

本文基于中国A股上市公司2009-2018年的数据,测算了企业价值对人民币汇率变动的敏感性。在此基础上,实证检验了汇率敏感性(企业价值对汇率变动的敏感程度)对企业贷款利率的影响和作用机制。研究发现:汇率敏感性与企业贷款利率之间显著正相关,且这种关系在拥有境外收入、境外投资和使用外汇衍生品的公司中更加显著。进一步分析发现,对于存在密切银企关系、较大的股东债权人利益冲突以及抵押品价值较低的企业,汇率敏感性与贷款利率之间的正相关关系更加显著。本文研究结果表明,随着我国市场化改革的进一步深化,贷款利率将会更加显著地反映企业的汇率敏感性特征。这种效应对于存在海外业务、银行更了解借款公司信息,以及违约可能性更高的公司更加明显。本文研究对于增强我国企业应对汇率风险能力,完善金融机构风险定价能力,引导金融机构服务实体企业具有一定参考意义。     

The cost of private debt over the credit cycle

We identify global and regional fluctuations in international private debt flows to emerging and developing countries using data on cross-border loans and international bond issuance over 1993–2009. We use micro-level data on syndicated cross-border loans and international bond placements to estimate the effects of individual borrower characteristics as well as macroeconomic conditions on the cost of foreign borrowing and test whether these effects differ across phases of the lending cycle. First, we find that borrower characteristics associated with lower loan spreads are not necessarily associated with lower bond spreads. Second, we find differential effects of borrower characteristics between cycle phases for loans and bonds separately. Third, we find strong reductions in the cost of debt finance during periods when international debt flows are more than one standard deviation above their mean, but not for expansionary periods, when the growth rate of debt flows is increasing. We also find that higher trade ratios in the borrower's home country raise loan spreads more in periods of high credit flows but have no effect on bond spreads. At the same time, borrowers residing in countries with high investment ratios pay lower spreads on bond issuance particularly during periods of high credit flows, but we find no similar effect for loan spreads. Inflation rates, real exchange rates and previous banking crises have small impacts on loan and bond spreads.     

Why is credit-to-GDP a good measure for setting countercyclical capital buffers?

We examine banks’ loan losses in Europe in 1982–2012 using a nonlinear three-factor model that takes into account output growth, real interest rate, and the ratio of private credit to GDP relative to its trend (i.e., “excessive indebtedness”). We find that a drop in output has an intensified impact on loan losses if the private sector is excessively indebted. Because increased bank credit risk should be matched with higher bank capital, the result motivates the Basel III's countercyclical capital buffers as a function of private indebtedness relative to its trend. The result also helps to explain differences in the amount of loan losses in different recessions across time and across countries. The model also indicates that low interest rates during the recent recession have clearly mitigated loan losses.     

疫情对企业融资的影响研究--来自银团贷款市场的经验证据

新冠肺炎疫情在全球蔓延,引发市场对企业经营、融资等问题的担忧。为进一步做好金融支持疫情防控工作、维护疫情期间金融市场稳定,本文通过研究历史视角下疫情对企业融资的影响机制,提出疫情防控期间金融支持相关的政策建议。本文利用1990-2018年汤森路透Dealscan数据库公布的企业银团贷款数据和手工收集全球重大疫情数据,实证研究了疫情对企业银团贷款的影响机制。研究发现:疫情发生后,企业银团贷款利率和贷款额度均显著增加,而银团贷款期限没有表现出显著变化。在考虑不同期限疫情观测时间窗和政策利率的滞后性影响等因素后,该结论依然成立。疫情对企业银团贷款的影响渠道包括避险情绪和融资流动性等。进一步研究发现,疫情期间政策利率调控效果有限,不同国家和地区的企业融资受疫情的影响存在差异。基于此,本文认为金融监管部门应进一步加大对企业信贷利率支持力度,完善货币政策有效性评估及动态调整机制,及时疏通货币政策传导,约谈恶意抬高信贷利率的金融机构,同时强化与财政、产业等政策的协调机制,合力支持疫情防控,维护经济金融稳定。     

Risk-based pricing of interest rates for consumer loans

By focusing on observable default risk's role in loan terms and the subsequent consequences for household behavior, this paper shows that lenders increasingly used risk-based pricing of interest rates in consumer loan markets during the mid-1990s. It tests three resulting predictions: First, the premium paid per unit of risk should have increased over this period. Second, debt levels should have reacted accordingly. Third, fewer high-risk households should have been denied credit, further contributing to the interest rate spread between the highest- and lowest-risk borrowers.For people obtaining loans, the premium paid per unit of risk did indeed become significantly larger after the mid-1990s. For example, for a 0.01 increase in the probability of bankruptcy, the corresponding interest-rate increase tripled for first mortgages, doubled for automobile loans and rose nearly six-fold for second mortgages. Additionally, changes in borrowing levels and debt access reflected these new pricing practices, particularly for secured debt. Borrowing increased most for the low-risk households who saw their relative borrowing costs fall. Furthermore, while very high-risk households gained expanded access to credit, the increases in their risk premiums implied that their borrowing as a whole either rose less or, sometimes, fell.     

The effect of reducing information asymmetry on loan price and quantity in the African banking industry

The purpose of this study is to assess how information sharing offices affect loan price and quantity in the African banking industry. The empirical evidence is based on a panel of 162 banks in 42 countries for the period 2001–2011. From the Generalised Method of Moments, public credit registries decrease loan price. With instrumental Quantile Regressions, two main findings are established. Public credit registries consistently decrease the price of loans whereas private credit bureaus consistently have the opposite effect. Public credit registries increase loan quantity in bottom quintiles (or banks associated with lower loan quantities) while private credit bureaus increase loan quantity in top quintiles (or banks associated with higher loan quantities).     

利率市场化、信贷资源配置与民营企业增长期权价值——基于贷款利率上、下限放开的准自然实验证据

利率市场化对于提高资金配置效率、推动经济高质量发展具有重要意义,来自企业的经验证据有助于理解利率市场化影响经济发展的微观路径。本文基于我国贷款利率上限与下限的放开,借助双重差分模型检验了利率市场化如何影响民营企业的信贷资源获取、投资灵活性与增长期权价值。研究表明:贷款利率市场化使得银行能够通过调节利率来匹配企业风险,相比于中等风险企业,高风险(低风险)企业在贷款利率上限(下限)放开后以更高(更低)的融资成本获得了更多信贷资源;信贷资源的增加为企业把握投资机会提供了资金支持,贷款利率上限(下限)放开后,高风险(低风险)企业的投资灵活性与增长期权价值显著提升。本文的研究发现有助于理解利率市场化促进经济增长的微观机制,为进一步健全市场化利率体系、推进经济高质量发展提供参考。     

Loan pricing under Basel capital requirements

We analyze the loan pricing implications of the reform of bank capital regulation known as Basel II. We consider a perfectly competitive market for business loans where, as in the model underlying the internal ratings based (IRB) approach of Basel II, a single risk factor explains the correlation in defaults across firms. Our loan pricing equation implies that low risk firms will achieve reductions in their loan rates by borrowing from banks adopting the IRB approach, while high risk firms will avoid increases in their loan rates by borrowing from banks that adopt the less risk-sensitive standardized approach of Basel II. We also show that only a very high social cost of bank failure might justify the proposed IRB capital charges, partly because the net interest income from performing loans is not counted as a buffer against credit losses. A net interest income correction for IRB capital requirements is proposed.     

年报风险信息披露与银行贷款利率

既有文献较少从银行视角关注年报风险信息披露的经济后果。银行更有能力解读年度风险信息,银行利益也更直接受到年报风险信息的影响,银行贷款利率更能体现年报风险信息披露的经济后果。本文基于2008-2017年单笔银行贷款利率数据的研究发现:总体上我国年报风险信息披露降低了银行贷款利率,说明我国年报风险信息披露更符合趋同观假说。中介效应检验发现:我国年报风险信息披露通过提高信息透明度,降低银行风险感知水平进而降低了银行贷款利率,即信息质量和风险是我国年报风险信息披露影响银行贷款利率的不完全中介。进一步分析发现:我国年报风险信息披露与银行贷款利率的负相关关系主要体现在货币政策紧缩组、非国有企业组以及公司治理水平较高组。本文首次研究银行贷款利率与年报风险信息披露的关系,有助于丰富风险信息披露文献和银行贷款文献。     

Bank loan losses-given-default: A case study

The empirical literature on credit risk has relied mostly on the corporate bond market to estimate losses in the event of default. The reason for this is that, as bank loans are private instruments, few data on loan losses are publicly available. The contribution of this paper is to apply mortality analysis to a unique set of micro-data on defaulted bank loans of a European bank. The empirical results relate to the timing of recoveries on bad and doubtful bank loans, the distribution of cumulative recovery rates, their economic determinants and the direct costs incurred by that bank on recoveries on bad and doubtful loans.     

The impact of the sovereign debt crisis on the activity of Italian banks

We examine the implications of the sovereign debt tensions on the Italian credit market by estimating the effect of the 10-year BTP-Bund spread on a wide array of bank interest rates, categories of loans and income statement variables. We exploit the heterogeneity between large and small intermediaries to assess to what extent the transmission of sovereign risk differed in relation with different banks’ balance-sheet characteristics and business strategies. Regarding the cost of funding, we find that changes in the BTP-Bund spread have a sizeable effect on the interest rates on term deposits and newly issued bonds but virtually no effect on overnight deposits. Furthermore, the sovereign spread significantly affects the cost of credit for firms and households and exerts a negative effect on loan growth. All these results are magnified when considering alone the five largest banks, which are typically less capitalized, have a larger funding gap and incidence of bad loans and rely more on non-traditional banking activities. Sovereign tensions also affect the main items of banks’ income statement.     

Legal Restrictions in Personal Loan Markets

This study examines the pricing of personal loans in the form of second mortgages to determine whether state-specific default laws have an effect on the availability and cost of that debt. We examine the pricing of loans to higher risk borrowers and whether borrowers in states that limit lender ability to seek default remedies pay higher credit costs. Our results indicate that, for the most part, lenders rationally price loans to higher risk borrowers. However, when we focus on borrowers with low credit scores, the results indicate that mean actual loan rates are higher than those predicted by our model. The results also indicate that state-specific default laws have an effect on the price of credit. Finally, the results show that there is a greater degree of error in the pricing of second mortgage loans to borrowers with low credit scores than to borrowers with high credit scores.
