National Public Finance Guarantee Corporation: History, Contacts, Portal, Claims, Services, AM Best Ratings, Financial Details and Reviews

The National Public Finance Guarantee Corporation has paved the way since 1985.

For nearly 40 years, they’ve been the backbone behind schools, roads, and so much more across the USA.

We use stuff all the time without realizing it’s because of the National and the stability they provide.

Without their insurance, making bond financing less risky, who knows how long projects would take or if they’d get done at all?

Their guarantees are why towns, cities, and states can afford to build things.

Next rec center or subway upgrade we see, we’ll think of National enabling it behind the scenes.

In this piece, I’m shining a light on their role.

Going to talk to people they’ve worked with for decades and help others appreciate what National contributes daily without most realizing it.

By the end, I hope anyone reading understands how National has unknowingly become synonymous with “trust” when it comes to public works and funding.

History of National Public Finance Guarantee Corporation

The National Public Finance Guarantee Corporation‘s history is pretty interesting.

They started as MBIA Insurance way back in 1985, but MBIA Inc. was formed even earlier in 1974 by five insurers who partnered up to guarantee municipal bonds.

In the 1980s, MBIA Inc. went public and expanded into new markets like structured finance overseas too.

Then the big change came in 2009 and split into two:

  1. National Public Finance Guarantee Corporation
  2. MBIA Insurance Corp.

National took on MBIA’s US public sector business while MBIA handled their trickier structured products that got hammered in the subprime crash.

Ever since, the National Public Finance Guarantee Corporation has been flying solo with its funding, leadership, and ratings.

It’s kind of wild to think they’ve been rolling solo for over a decade after 40 years under the MBIA banner.

But it’s clear National’s established itself well as an independent player dedicated to municipal finance.

Their past under MBIA must’ve prepared them well for the long haul.

National guarantees bondholders will get paid on time, which is a huge peace of mind.

If the issuer can’t make the payment for some reason, the bondholder simply files a claim with National.

Then National kicks in to make sure that payment still gets delivered no matter what.

That’s the beauty of their insurance it removes all the risk from the individual investors.

National says:

“Don’t worry, we’ve got your back. You’ll be paid even if something happens to the issuing city or state.”

No wonder they’ve been such a bedrock for public money raising all these years.

The claim process is as follows:

  • The bondholder must notify National of the payment default by sending a notice of default form to National’s claims department. The notice of default form can be downloaded from the customer portal or requested from National’s customer care phone number.
  • The bondholder must also provide proof of ownership of the insured bond, such as the original bond certificate, the confirmation statement, or the account statement.
  • National will verify the claim and the bondholder’s identity and eligibility. National will also contact the issuer of the insured bond to confirm the payment default and the amount due.
  • If the claim is valid and approved, National will make the payment to the bondholder within 10 business days of receiving the claim. National will pay the amount of principal and interest that is due on the insured bond, plus any accrued interest from the date of default to the date of payment.

Customer reviews of National Public Finance Guarantee Corporation

What are the benefits of a National Public Finance Guarantee Corporation for investors?

The National can provide investors with some benefits:


  • Protection against issuer default and downgrade risk: If an issuer defaults on its debt obligations, National will be obligated to pay the principal and interest on the bonds. This can protect investors from losses that they would otherwise incur if the issuer defaults.
  • Enhancing liquidity for secondary market trading: National guarantees can enhance liquidity for secondary market trading of bonds. This is because investors are more willing to purchase bonds with a National guarantee, as they know that the bonds will be paid if the issuer defaults.
  • Simplifying risk assessment: National guarantees can simplify risk assessment for investors. This is because investors do not need to worry about issuer default risk as much when they are investing in bonds with a National guarantee.


  • Reduced Potential Returns: Because National guarantees diminish the risk of issuer default, investors might request lower interest rates on the bonds. Consequently, investors could experience diminished returns on their investments.
  • Limited Participation in Potential Gains: If the issuer’s creditworthiness improves, those holding National-guaranteed bonds won’t directly benefit from any increase in the bonds’ value, as the guarantee remains unchanged.
  • Greater Dependence on the Guarantor: Investors become more reliant on the financial stability of the guarantor, National Public Finance Guarantee Corporation (National), as their protection against issuer default hinges on National’s capacity to fulfill its commitments.
  • Potential for Moral Hazard: If investors view National as a safety net, issuers may have less incentive to uphold sound financial practices, potentially elevating the risk of future defaults.
