Fraud, banking crisis, and regulatory enforcement: Evidence from micro-level transactions data

Can widespread fraud cause large scale banking crises? We address this issue in the context of the recent Turkish banking crisis of 2000, which was followed by a severe recession and currency crisis. Using detailed micro-level transactions data, we show that related lending and back-to-back loans across banks were used to circumvent regulation and transfer deposits to private holding companies that were ruined. Our evidence suggests that systemic fraud coupled with weak enforcement of conventional regulatory principles can be a source of banking crisis.
