An Academic Response to Basel 3.5

چکیده
Recent crises in the financial industry have shown weaknesses in the modeling of Risk-Weighted Assets (RWAs). Relatively minor model changes may lead to substantial changes in the RWA numbers.

In particular, we frame this discussion in the context of two recent regulatory documents we refer to as Basel 3.5.
