This paper introduces a new concept of regulatory capital arbitrage that can be performed under the “standardised approach” of the new Basel Capital Accord when the return on regulatory capital does not increase monotonically with the credit risk of financial assets as proxied by external ratings. We demonstrate that this arbitrage opportunities arises, for certain credit risk levels, in 90% of trading days between 1993 and 2005.

Abstract
This paper introduces a new concept of regulatory capital arbitrage that can be performed under the “standardised approach” of the new Basel Capital Accord when the return on regulatory capital does not increase monotonically with the credit risk of financial assets as proxied by external ratings. We demonstrate that this arbitrage opportunities arises, for certain credit risk levels, in 90% of trading days between 1993 and 2005.
