From 1990 to 1993, the typical firm on the Tokyo Stock Exchange lost more t
han half of its value, and banks experienced severe adverse shocks. We show
that firms whose debt had a higher fraction of bank loans in 1989 performe
d worse from 1990 to 1993 and also invested less than other firms did. This
effect holds when we control for variables that affect firm performance. W
e show further that exogenous shocks to banks during the negotiations leadi
ng to the Basle Accord affected bank borrowers significantly.
