Monoline insurers play a critical role in modern-day Credit Enhancements; they are more effective in (a) off-balance-sheet models creating synthetic collateral, (b) sovereign ratings' enhancement with built-in asset derivatives and (c) cross border loans with receivables and counterparties in the domain and jurisdiction of the monoline insurer. The decision whether to use a monoline insurer or not often depends upon the cost of such cover vis-a-vis the improvement in pricing for the loan or bond issue by virtue of such credit enhancement.
