On credit enhancement for infrastructure financing in Pakistan of State Bank of Pakistan. Credit enhancement has emerged over the past decade as a critical factor in the development of credit markets in developing and transitional countries. Credit enhancement is especially crucial in the development of market-based systems as distinct from government-run systems since private lending institutions have had relatively little experience with financing government investments in the developing world. Credit enhancement strategies are designed to mitigate the risks associated with lending and therefore foster the growth of the overall credit system.
