We examine changes in bank risk following the passage of the Riegle–Neal Act of 1994 and find a significant decline in bank risk. The extent of interstate banking activity and the status of state-level interstate banking laws are important in explaining the risk reduction. Banks with assets in multiple states experience a significant reduction in risk whereas banks with assets in one state experience no significant change in risk. Banks in states with the most restrictive interstate banking provisions experience a significant decrease in risk whereas banks in states with more liberal interstate banking provisions experience a significant increase in risk.
