Simply put, “municipal bond insurance got its start as a way to protect investors if their bond issuer defaulted,” as Rich White explains in a recent Investopedia article entitled Fatal Seduction of the Municipal Bond Insurers.”

The overall credit quality of an insured municipal bond can be likened to a double jet engine plane, according to Richard Ciccarone, Managing Director and Chief Research Officer at McDonnell Investment Management LLC. “Just as passengers would hope that both plane engines were equally strong, with one able to function in case the other were to malfunction, municipal bond investors have come to expect that their insured investments are supported by a strong underlying credit and an equally strong guarantee from the insurer,” he explains.

Historically, bond insurance saved governmental bodies money by allowing them to qualify for lower lending rates than they would get on their own. By enhancing their credit quality through bond insurance, issuers were able to increase demand for offerings in the primary and secondary trading markets.

Over the past decade, the bond insurance companies became bolder, securing riskier securities beyond traditional municipal bonds in order to increase their returns. One area into which they ventured was the housing market. But what they seemed to have missed were signs of increasingly lax lending standards that ultimately led to today’s subprime mortgage crisis. And the insurance companies were blind-sighted by the high level of default and delinquencies that require far more capital than ever anticipated.

As a result, today’s bond insurance industry is plagued by uncertainties, with implications that profoundly impact the municipal bond market. What makes this situation so difficult to grasp is that it changes almost daily.
