Under the market-based approach, institutions are permitted to calculate the minimum capital requirements for their banking book equity holdings using one or both of two separate and distinct methods: a simple risk weight method or an internal models method.
The method used should be consistent with the amount and complexity of the institution’s equity holdings and commensurate with the overall size and sophistication of the institution.
Supervisors may require the use of either method based on the individual circumstances of an institution.
Under the simple risk weight method, a 300% risk weight to be applied to publicly traded, and 400% for all others.
•
If an internal model is used, minimum quantitative and qualitative requirements would have to be met on an ongoing basis, including a minimum capital charge be no less than the capital charge that would be calculated under the simple approach at a risk weight of 200% for publicly traded, and 300% for other equities.
