The Transmission of Monetary Policy to Corporate Investment: the Role of Loan Renegotiation
Accepted, AEJ: Macroeconomics [Most Recent] [Supplemental Appendix] [Economic Discussion Paper Series]
I construct a novel dataset comprising over 100,000 loan observations from U.S. firms and estimate that renegotiating existing loans - rather than originating new loans - significantly contributes to the corporate investment response to monetary policy shocks, accounting for about a half of the aggregate effect. Expansionary monetary policy shocks increase bank credit predominantly through renegotiations, and in turn, firms that renegotiate boost investment the most. By contrast, new loan issuance is driven by the firm's investment growth prior to the shocks, consequently contributing only a tenth to the overall investment response. Notably, renegotiations amplify investment responses for financially constrained firms. These findings unveil novel dimensions of the channels through which monetary policy affects corporate investment.
Cyclical Divergence in Corporate Lending and the Real Effects [Most Recent]
Using text analysis of loan agreements filed with the US Securities and Exchange Commission (SEC), this study offers a new perspective on the conventional view of uniformly procyclical loan activities by revealing distinct cyclical patterns - procyclical originations and countercyclical renegotiations - particularly during the Global Financial Crisis. The empirical evidence clarifies the underlying mechanisms, showing that firm financial characteristics drive these dynamics: weaker firms are more likely to renegotiate but less likely to secure new loans, a pattern that intensifies during the crisis. Despite more frequent renegotiations, loan terms remain procyclical, with lower loan amounts, higher spreads or shorter maturities limiting investment and deepening downturns. The impact on investment varies by firms' financial health, with riskier firms exacerbating declines during the crisis due to higher renegotiated interest rates, while healthier firms boosting investment in normal times due to improved terms. This heterogeneity highlights a cyclical asymmetry in the role of firm financial health: stronger firms lead investment during expansions, while weaker firms are crucial during contractions.
