Bank Heterogeneity and Interest Rate Setting: What Lessons Have We Learned since Lehman Brothers?

A substantial literature has investigated the role of relationship lending in shielding borrowers from idiosyncratic shocks. Much less is known about how lending relationships and bank‐specific characteristics affect the functioning of the credit market in an economy‐wide crisis. We investigate how bank and bank–firm relationship characteristics have influenced interest rate setting since the collapse of Lehman Brothers. We find that interest rate spreads increased by less for those borrowers having closer lending relationships. Furthermore, firms borrowing from banks endowed with large capital and liquidity buffers and from banks engaged mainly in traditional lending were kept more insulated from the financial crisis.     

The effect of relationship banking on firm efficiency and default risk

Does relationship bank oversight reduce firm default risk and improve firm operational efficiency? I find that a new loan from a relationship bank reduces the default probability and increases the efficiency of a borrowing firm, benefiting both banks and borrowers. Moreover, inefficient and less creditworthy firms experience the highest reductions in their default risks and improvements in their efficiencies in the years following new relationship bank loans. Further, these benefits are disrupted when the relationship bank is acquired.     

Mutual guarantee institutions and small business finance

A large body of literature has shown that small firms experience difficulties in accessing the credit market due to informational asymmetries. Banks can overcome these asymmetries through relationship lending, or at least mitigate their effects by asking for collateral. Small firms, especially if they are young, have little collateral and short credit histories, and thus may find it difficult to raise funds from banks. In this paper, we show that even in this case, small firms may improve their borrowing capacity by joining Mutual Guarantee Institutions (MGI). Our empirical analysis shows that small firms affiliated to MGIs pay less for credit compared with similar firms. We obtain this result for interest rates charged on loan contracts which are not backed by mutual guarantees. We then argue that our findings are consistent with the view that MGIs are better at screening and monitoring opaque borrowers than banks are. Thus, banks benefit from the willingness of MGIs to post collateral since this implies that firms are better screened and monitored.     

Does lending relationship help or alleviate the transmission of liquidity shocks? Evidence from a liquidity crunch in China

We examine China’s June 2013 liquidity crunch as a negative shock to banks and analyze the wealth effects on exchange-listed firms. Our findings suggest that liquidity shocks to financial institutions negatively impact borrower performance, particularly borrowers reporting outstanding loans at the end of 2012. Stock valuations of firms with long-term bank relationships, however, outperform the market and experience smaller subsequent declines in investment than peers lacking solid banking relationships. This effect is the strongest for firms that enjoy good relations with China’s large state-owned banks or foreign banks, and weakest for firms whose connections are solely with local banks. We document a positive correlation between the stock performances of firms and the stock performances of lender banks and the likelihood of lender banks operating as net lenders in the interbank market. These results suggest that banks transmit liquidity shocks to their borrowing firms and that a long-term bank-firm relationship may mitigate the negative effects of a liquidity shock.     

Collateralization of business loans: Testing the prediction of theories

Using confidential data on a large sample of relationship lending, we analyze the determining factors of the collateralization of business loans from banks, distinguishing between firms with observable risk and firms with hidden information. We achieve three main results. First, we provide evidence that observably riskier borrowers are encouraged to give more collateral to banks to obtain a loan, whereas firms with hidden information are less risky borrowers, offering collateral to signal their quality. Second, we show that relationship banking has a direct impact on the use of collateral and produces moderating effects on the other determining factors. Finally, we observe that distant bank branches—i.e., branches that encounter greater difficulties collecting soft information and obtaining site-specific data from headquarters—are more likely to require collateral than local bank branches.     

Winners and losers from supervisory enforcement actions against banks

We investigate how supervisory enforcement actions (EAs) against banks affect their business borrowers. We find negative short-term valuation effects of EAs for large relationship borrowers, which are reversed after new loans are granted. Large non-relationship borrowers' valuations are unaffected by EAs, but turn negative after relationships are established with sanctioned banks. Additionally, sanctioned banks appear to offset uncertainty and reputational damage of EAs by improving credit terms and availability for relationship and non-relationship large businesses, but decrease credit availability to small businesses. The small business credit contraction may have significant negative economic consequences due to bank dependency and credit constraints.     

Are all types of real transaction management equal in the eyes of bank lenders?

This study examines whether bank lenders react differently to various types of real transaction management (RTM) by borrowing firms. Drawing upon the differential cash and cash flow effects of alternative forms of RTM, we predict and find that banks provide more favorable loan terms, that is, lower interest spread and reduced likelihood of required collateral, for firms reporting more discretionary reductions in research and development (R&D) expenditures. In contrast, lending banks respond unfavorably to borrowers’ engagement in RTM through aggressive sales discounts and overproduction of inventories. Additional analysis reveals that the favorable effect of discretionary R&D reductions on loan pricing is greater (smaller) for borrowing firms with a prior relationship with the bank or with a lower level of cash holdings (loans with longer maturity). Overall, our findings suggest that banks, with their unique payoff functions and monitoring incentives, do not view all forms of RTM negatively.     

How important are small banks to small business lending?: New evidence from a survey of small firms

Typically, small banks lend a larger proportion of their assets to small businesses than do large banks. The recent wave of bank mergers has thinned the ranks of small banks, raising the concern that small firms may find it difficult to access bank credit. However, bank consolidation will reduce small business credit only if small banks enjoy an advantage in lending to small businesses. We test the existence of a small bank cost advantage in small business lending by conducting the following simple test: If such advantages exist, then we should observe small businesses in areas with few small banks to have less bank credit. Using data on small business borrowers from the 1993 National Survey of Small Business Finance, we find that the probability of a small firm having a line of credit from a bank does not decrease in the long run when there are fewer small banks in the area, although short-run disruptions may occur. Nor do we find that firms in areas with few small banks are any more likely to repay trade credit late, suggesting that such firms are no more credit constrained than firms in areas with many small banks.     

Do Banks Follow Their Customers Abroad?

The market share of US business loans made by foreign‐owned banks has increased dramatically since 1980. At the same time, foreign direct investment in the US rose, so that much of the growth in foreign‐owned US‐based bank lending to businesses in the US could conceivably be accounted for by an increase in loans to the nonbank US affiliates of firms headquartered abroad, an expectation consistent with the conventional wisdom that banks "follow their customers" abroad. Our study investigates the lending patterns of US‐based banks from Japan, Canada, France, Germany, the Netherlands, and the UK, countries that account for the vast majority of foreign bank activity in the US. Simultaneously, we look at the borrowing patterns of nonbank US affiliates of firms from those countries. We find that banks from four of the six countries (Japan, Canada, the Netherlands, and the UK) allocated a majority of their loans to non‐home‐country borrowers for some or all of the 1981–1992 period. These findings suggest that the "follow the customer" hypothesis may have a more limited applicability than previously supposed.     

Did quantitative easing reduce the borrowing costs of firms? The risk-taking channel

This paper examines the effect of the Federal Reserve's quantitative easing (QE) on the cost of bank loans and documents large heterogeneous effects across different firms. In QE1, the average loan spread is 22.7 percent lower compared to the non-QE period. This effect falls in QE2 and OT and then rises in QE3 and the tapering period. The rates of riskier loans are restrained more than less risky loans during QEs as banks take more risks by offering lower rates to attract risky borrowers. The Fed mortgage-backed securities purchases have a larger impact in narrowing the borrowing cost difference between riskier and safer loans than the Fed Treasury purchases. Our results are robust to borrower, year-quarter and bank fixed effects. Overall, our findings support that the risk-taking channel of QE plays a significant role in the corporate bank loan market.     

Do small businesses still prefer community banks?

We formulate and test hypotheses about the role of bank type – small versus large, single-market versus multimarket, and local versus nonlocal banks – in banking relationships. The conventional paradigm suggests that “community banks” – small, single-market, local institutions – are better able to form strong relationships with informationally opaque small businesses, while “megabanks” – large, multimarket, nonlocal institutions – tend to serve more transparent firms. Using the 2003 Survey of Small Business Finance (SSBF), we conduct two sets of tests. First, we test for the type of bank serving as the “main” relationship bank for small businesses with different firm and owner characteristics. Second, we test for the strength of these main relationships by examining the probability of an exclusive relationship and main bank relationship length as functions of main bank type and financial fragility, as well as firm and owner characteristics. The results are often not consistent with the conventional paradigm, perhaps because of changes in lending technologies and deregulation of the banking industry.     

Rules versus discretion in loan rate setting

Loan rates for seemingly identical borrowers often exhibit substantial dispersion. This paper investigates the determinants of the dispersion in interest rates on loans granted by banks to small and medium sized enterprises. We associate this dispersion with the loan officers’ use of “discretion” in the loan rate setting process. We find that “discretion” is most important if: (i) loans are small and unsecured; (ii) firms are small and opaque; (iii) the firm operates in a large and highly concentrated banking market; and (iv) the firm is distantly located from the lender. Consistent with the proliferation of information-technologies in the banking industry, we find a decreasing role for “discretion” over time in the provision of small credits to opaque firms. While widely used in the pricing of loans, “discretion” plays only a minor role in the decisions to grant loans.     

Risky lending: Does bank corporate governance matter?

We study the effect of bank governance on risk-taking in commercial lending. Banks with more effective boards are less likely to lend to riskier borrowers. This effect is restricted to periods of distress in the banking industry and is stronger at banks with board-level credit committees. Banks with more effective boards are less likely to lend to riskier borrowers right after the Russian default, which exogenously imposed distress conditions on U.S. banks. Thus, value-maximizing banks appear to ration credit to riskier borrowers precisely when such firms might be credit-constrained, suggesting that bank governance regulations may have potential unintended consequences.     

The changing structure of local credit markets: Are small businesses special?

In many countries consolidation in the banking industry has reduced the number of small banks and led to significant shifts in market shares; deregulation has fostered entry in local credit markets and the expansion of branch networks, increasing competition in local markets. Small businesses are believed to be more vulnerable to these changes, since they are more dependent on credit from local banks. In this paper we investigate the consequences of consolidation and entry for these borrowers compared with those for large firms. We employ a data set for Italy, which provides information on volumes of loans and bad loans by size of borrower with a detailed geographical partition. We find that mergers are followed by a temporary reduction in outstanding credit to all sizes of borrowers and by an increase in bad loans, most likely due to the reassessment of banks portfolios. Entry has a relatively persistent negative impact on credit supply to small and medium-sized firms. Our results also show that concentration, branch density and the share of branches of small banks affect the volumes of credit and bad loans of small borrowers.     

The market reaction to debt announcements: UK evidence surrounding the global financial crisis

We examine the stock market response to announcements of public, bank and privately placed debt issuance by large UK firms surrounding the global financial crisis of 2008. Prior to the crisis, we find that stock prices respond positively to announcements of bank debt issuance only. This is restricted to the sub-sample of syndicated bank loans and this is suggestive of the certification from multiple lenders conveying a signal of creditworthiness. We find that abnormal returns on the announcement of bank loans have declined since the financial crisis, both in absolute terms and in comparison to alternative borrowing sources. Overall, our results suggest that surrounding the global financial crisis of 2008, bank loans have become less informative as a signal of the creditworthiness of borrowing firms.     

When bank loans are bad news: Evidence from market reactions to loan announcements under the risk of expropriation

In this paper we investigate whether inefficient bank loans can reduce the value of borrowing firms when expropriation of the stock of minority shareholders by controlling shareholders is a major concern. Using data from Chinese banks, we find that bank loan announcements generate significantly negative abnormal returns for the borrowing firms. In line with this expropriation view, negative stock price reactions following bank loan announcements are concentrated in firms that are perceived to be more vulnerable to expropriation by controlling shareholders. Finally, we find evidence that a negative relationship between market reactions and firm vulnerability to expropriation exists only when firms borrow from the least efficient banks.     

Bankruptcies of small firms and lending relationship

This paper empirically investigates the role played by relatively small banks in the Japanese local credit market. We test the hypothesis that small banks enhance the recovery rate from the financial distress and reduce the bankruptcy ratio of small firms. Empirical evidence suggests that small banks specialize more in relationship loans to small firms. However, this expertise is limited to the loans to unincorporated firms or those with a very small number of employees.     

Product market competition and the cost of bank loans: Evidence from state antitakeover laws

The extant literature documents a positive relationship between a firm’s takeover vulnerability and its agency cost of debt. Using state antitakeover laws as an exogenous measure of variation in takeover vulnerability, I investigate whether product market competition has a disciplinary effect that can lower a firm’s cost of bank loans. After taking into account the industry composition of borrowers, I find that banks charge higher spreads to borrowers that are vulnerable to takeovers, but only in concentrated industries. In the absence of disciplinary competitive pressure, the effect of takeover vulnerability on the cost of bank loans is mitigated for larger firms, firms followed by analysts, firms with existing credit ratings, non-family firms, and for borrowers with shorter maturity loans or loans with covenants and collateral in place. Taken together, the results suggest that the effect of governance on the cost of financing is not homogenous across all industries, and that concentrated industry firms may need to use supplementary governance mechanisms to mitigate debt holder agency problems.     

Should banks own equity stakes in their borrowers? A contractual solution to hold-up problems

This paper develops a model to answer the question whether a bank should hold a share of the equity of a borrowing firm. The model shows that a small equity stake held by the bank can have a significant and positive impact on the lending relationship. The benefit of bank equity participation arises from the reduced ability of the bank to extract rents from the firm in multiple rounds of financing. This, in turn, improves the firm’s incentive to make investments in profitable projects that require future outside finance. The benefit is likely to be significant for small to medium size firms, growth firms, and firms with ongoing capital needs. The paper addresses, from a corporate finance perspective, the current debate about whether banks should be allowed to own equity stakes in corporations – and how large these equity stakes should be.     

Bank Competition and Loan Quality

We analyze the impact of bank competition on the equilibrium quality of loans in a formal model where banks do not observe the type of loan applicants, i.e. face an adverse selection problem, nor borrowers’ effort, i.e. also face a moral hazard problem. The main finding is that there exists an inverted U-shaped relationship between competition and the average quality of loans. Policy implications are derived from this result and from an extension to the basic model where banks may sequentially acquire information about potential borrowers.
