Moral Obligation Bonds: A Commitment Beyond Legal Obligation

Moral Obligation Bonds: A Commitment Beyond Legal Obligation

4 Min.

Moral Obligation Bonds are a unique financial instrument that bridges the gap between traditional municipal bonds and a moral commitment to creditors. These bonds are issued by municipalities or government bodies, offering investors not only tax-exempt benefits but also the assurance of a moral pledge to avoid defaulting on payments. In this comprehensive guide, we will delve into the intricacies of Moral Obligation Bonds, their structure, and the significance of their moral commitment to both issuers and investors.


Municipal bonds, widely known as munis, serve as a primary source of funding for various government projects. There are two main categories of municipal bonds:

  1. General Obligation Bonds (GO Bonds): These bonds are supported by the full faith and credit of the municipal government. The government can increase taxes to meet its payment obligations on these bonds.
  2. Revenue Bonds: The payment obligations for revenue bonds are backed by the revenue generated by the specific project they finance. These bonds do not rely on the government's financial coffers.

Understanding Moral Obligation Bonds

Moral Obligation Bonds fall under the broader category of revenue bonds. What sets them apart is their unique structure, which includes a moral pledge to protect lenders against default. This moral commitment is not legally binding, but it holds substantial weight with investors.

To enhance the credibility of this moral commitment, the issuing body establishes a reserve fund. This fund is intended to cover any debt service costs that the government might be unable to meet. While it's not a legal obligation to avoid default, the moral imperative associated with Moral Obligation Bonds plays a pivotal role in reassuring investors.

The Role of the Moral Pledge

Moral Obligation Bonds are secured by a non-binding covenant, allowing the government to appropriate funds to address any shortfalls in servicing the debt. This added layer of security is morally binding, not legally. However, the promise is considered as credible as a legally binding commitment. Why? Because the issuing government faces the prospect of a negative credit rating impact if it fails to honor this pledge.

Practical Example

To illustrate this concept, let's consider a practical example. Suppose a municipality issues a bond to finance the construction of a major city airport. The revenue generated by the airport services is earmarked for servicing the bond and repaying the principal upon maturity. If the airport's revenue falls short of the required amount to cover interest payments, the government cannot increase taxes to make up the deficit. Instead, with a Moral Obligation Bond, the issuer is obligated to actively seek alternative financing routes to fulfill its interest and principal payments to investors.

Higher Level of Risk

The absence of the full faith and credit of the issuer means bondholders bear a higher level of risk. If the government defaults on its payments, bondholders may lose their entire investments. Consequently, Moral Obligation Bonds typically offer a higher yield compared to General Obligation Bonds, compensating investors for the elevated risk. Additionally, the interest income earned from Moral Obligation Bonds is exempt from federal taxes and, in most cases, from state taxes, provided the investor resides in the issuing state or municipality.


Moral Obligation Bonds offer investors the benefits of tax-exempt status and a significant moral commitment from the issuing government to avoid defaults. Although not legally binding, the moral pledge holds substantial credibility as governments face the consequences of damaged credit ratings if they fail to honor it. Investors need to be aware of the higher risk involved, as the absence of full faith and credit backing means potential loss of investments in the event of a default. However, the higher yield and tax advantages make Moral Obligation Bonds an attractive option for many investors. In summary, these bonds represent a unique combination of financial commitment and moral responsibility, showcasing the delicate balance between financial prudence and moral obligation in the municipal finance world.
