Banks as delegated risk managers

Abstract

Risk management, although of major importance in the banking industry in practice, plays only a minor role in the theory of banking. We reduce this gap by putting forward a model in which risk managers - specialists that can find out correlations between risky assets - endogenously take over typical functions of banks. They grant loans, they consult on financial questions with firms that are threatened by bankruptcy, and they sign tailor-made hedge transactions with these firms. Delegation costs are innately low if banks assume the function of risk managers in an economy. Risk management can be seen as a core competence of banks
