How MBIA Insurance Corporation Works
MBIA Insurance Corporation provides insurance to back municipal bonds, also known as munis. In order to boost investor confidence, many cities (the issuer of municipal bonds) will purchase insurance through MBIA Insurance Corporation to get a higher rating and guarantee the bonds. Bond issuers may find they can even lower the total cost of issuing debt by purchasing MBIA insurance, as the higher rating the bonds garner, the lower the issuer can adjust the coupon rate when presenting to investors.
MBIA insurance is purchased the same way other types of insurance are, with the policyholder selecting specific amounts of coverage and an underwriter calculating the risks to the insurer of providing this coverage in order to determine the price of the insurance. The risks are calculated by the likelihood that the bond issuer will default on the bond and MBIA will have to pay out to investors, so the stability of the project the bond funds is the key indicator of risk.
If the project succeeds and raises the money the issuer predicts it will, the issuer can easily pay investors without a need to invoke MBIA's insurance coverage. If the project does not succeed, the issuer will not have the funds to pay investors and will default.
MBIA and its competitors try to keep their own credit ratings at the highest levels, as this makes their services much more valuable to clients and investors. A bond issuer is unlikely to pay for insurance from a company with a bad credit rating that might default on paying out to investors. As a result, MBIA aims to keeps its credit rating high by diversifying its insured portfolios across nation, sector, and asset classes.
In addition, MBIA also keeps certain measures of financial leverage below dangerous thresholds. This means that they do not take on too many clients that are high-risk, even though they could charge these clients higher premiums. The net present value of those higher premiums does not exceed the financial loss that could occur from those clients defaulting and the insurer having to pay out the covered amount.
