Main bank impairment and corporate cash holdings during the global financial crisis

This paper examines how the impairment of main banks' balance sheets affects corporate cashholding behavior during the 2008 financial crisis using a firm-bank matched panel dataset of 2,520 firms in Japan. The major findings of this paper are as follows. First, the impairment of main banks increases firms' cash holdings during this financial crisis. Second, this tendency is more pronounced among firms with limited financing sources and those with unstable main bank relationships. Third, holding large amounts of cash increases the value of firms with main bank impairment during the 2008 financial crisis.
