This paper investigates whether monitoring by bank lenders affects CEO incentives of borrowing firms. We find that an increase in bank monitoring incentives significantly reduce the sensitivity of CEO wealth to stock return volatility (Vega). The results are more profound when bank lenders are more powerful and reputable and have a prior lending relationship with the borrowing firms. Additionally, Vega decreases after financial covenant violations and increases when bank lenders have offsetting equity stakes in borrowing firms. The reduction in Vega due to bank monitoring has some real effects on borrowing firms’ corporate policies. These results together suggest banks have a unique role in monitoring and shaping CEO incentives to mitigate the risk-shifting incentives of firm managers.

Syndication increases the overlap of bank loan portfolios and makes them more vulnerable to contagious effects. We develop a novel measure of bank interconnectedness using syndicated corporate loan portfolios, overlap based on industry and region, and different weights such as equal weights, size and relationships. We find that interconnectedness is driven mainly by bank diversification, less by bank size or overall loan market size. Interconnectedness is positively correlated with different bank-level systemic risk measures including SRISK, DIP and CoVaR, and such a positive correlation mainly arises from an elevated effect of interconnectedness on systemic risk during recessions. Overall, our results highlight that institution-level risk reduction through diversification ignores the negative externalities of an interconnected financial system.
