A Capital Adequacy Buffer Model

Author

Listed:

Abstract

In this paper, we develop a new capital adequacy buffer model (CABM) which is sensitive to dynamic economic circumstances. The model, which measures additional bank capital required to compensate for fluctuating credit risk, is a novel combination of the Merton structural model, which measures distance to default, and the timeless capital asset pricing model (CAPM) which measures additional returns to compensate for additional share price risk.
