We propose an option-based model that examines the relationships among municipal bonds with prepackaged insurance, capital insurance, and optimal bank interest margins. If the elasticity effect is positive (negative), then an increase in the bond insurance premium will increase the bank's optimal loan rate (optimal deposit rate). If the elasticity effect is negative (positive), then an increase in the capital-to-deposit ratio will increase (decrease) the bank's optimal loan rate. But an increase in the capital-to- deposit ratio increase the bank's optimal deposit rate under the positive elasticity effect.
