The credit insurance market has lost several participants and this method of reducing overall debt costs will not be as readily available in the future. Several respondents believe that this market is flawed in any case with the risk premiums charged by the credit insurers not an accurate reflection of the risks that they had cumulatively absorbed, especially toll road patronage risk. The result has been balance sheets with a high level of exposure to under-performing assets. Another didn't believe that credit insurers had absorbed unmanageable risks but considered the underlying instability of debt markets stemmed from low real returns and distortions introduced by government intervention in recent weeks. This had affected the yield curve and spreads between AAA and BBB-corporate debt. It was also suggested that another two toll roads were performing well below targeted patronage levels and in the case of one, the servicing of debt was supported by the credit insurer. The future of the credit insurers had more to do with the strength of their provisioning than their appetite for new business.
