Inter-Firm Relationships and the Special Role of Common Banks
with Emanuela Giacomini and Andy Naranjo
Abstract: Using a novel dataset that combines information on customer-supplier trade relationships with information on firm-bank lending relationships, we show that common banks that lend to firms at both ends of a trade link grow and strengthen such trade relationships. To establish causality, we use bank mergers, which generate exogenous variations in the presence of common banks, and show that common bank relationships between customers and suppliers increase trade relationships by 41.5%. We find that the role of a common bank is greater when it is more informed and when supply chains suffer from larger information and holdup problems. We also document that suppliers with common banks face lower bankruptcy spillover risks from a distressed customer, adopt a focused customer base, and invest more in relationship specific assets. Lastly, we show that common banks play a central role in facilitating provision of trade credit by suppliers during periods of systemic distress (e.g., the Great Recession). Overall, our findings show the unique role of banks in driving inter-firm growth and investment by mitigating information and holdup problems, which arguably leads to greater economic growth.

Abstract: The sustainable loan market has flourished amid the widespread issuance of ESG-linked loans with spreads contingent on borrower ESG performance. These loans are issued mostly as revolving credit facilities to large firms with superior ESG profiles by global relationship banks. ESG-linked loans vary widely in the quality of their contractual disclosures, and borrower ESG scores deteriorate after the issuance of low disclosure quality ESG-linked loans. Stock markets respond positively to the announcement of ESG-linked loan issuance only if disclosure quality is high, indicating the importance of transparent disclosure of ESG contingencies in the sustainable lending market.
