We show corporate-level real, financial, and (bank) risk-taking effects associated with calculating loan provisions based on expected-rather than incurred-credit losses. For identification, we exploit unique features of a Colombian reform and supervisory, matched loan-level data. The regulatory change induces a dramatic increase in provisions. Banks tighten all new lending conditions, adversely affecting borrowing-firms, with stronger effects for risky-firms. Moreover, to minimize provisioning, more affected (less-capitalized) banks cut credit supply to risky-firms- SMEs with shorter credit history, less tangible assets or more defaulted loans-but engage in "search-for-yield" within regulatory constraints and increase portfolio concentration, thereby decreasing risk diversification
