Embodiments consistent with the present invention provide a credit enhancement structure for risk allocation between parties that minimizes the regulatory capital reserve requirement impact to an institution subject to capital reserve requirement. A subject pool of assets held by the institution, such as a pool of loans, is rated to determine its risk levels. Based on the rated risk levels, a guarantor party agrees to be responsible for a portion of the risk associated with the pool of assets, which may define the maximum risk exposure of the institution holding the asset pool. The risk-rated capital reserve requirements are applied to the asset pool based on the risk level rating and the guarantor's agreed upon risk responsibility such that the institution holds a reduced amount of reserve capital compared to what it would otherwise be required to hold.
