“Agency bonds” is a broad term that encompasses various types of securities issued by government-related entities. For example, bonds issued under the Rural Electrification Program are managed through the Federal Financing Bank, a division of the U.S. Treasury that assists federal agencies in raising funds.

Generally, bonds issued by federal agencies are considered to have a similar risk-free credit status as Treasury securities, reflecting a strong level of security for investors.

Another category is Ginnie Mae securities, which are government-backed and free from credit risk, though they are issued by private companies. Positioned between the federal government and publicly traded companies are government-sponsored enterprises (GSEs). These entities operate as corporations under government charters that define their specific missions.

GSE-issued bonds typically offer higher yields than Treasurys and are perceived as having near-zero credit risk, although they do not come with a formal guarantee.

How do agency bonds work?

A bond issued or guaranteed by U.S. federal agencies or government-sponsored enterprises is known as an agency bond. These securities are commonly traded through broker-dealers.

Agency bonds generally offer higher liquidity compared to many other bonds. However, they do not have the same full federal guarantee as Treasuries and can be less liquid than Treasury securities. Consequently, while agency bonds typically provide higher interest rates than Treasuries, their relative lack of liquidity might make them less suitable for some investors.

Agency bonds come in various structures, coupon rates, and maturities.

Discount notes mature in less than a year and, similar to Treasury bills, do not pay a coupon. Instead, they are purchased at a discount and redeemed at face value upon maturity. The interest earned is the difference between the purchase price and the face value.

Zero-coupon bonds, or “zeros,” are created by securities firms from agency bonds. These bonds do not pay periodic interest. Instead, interest accrues and compounds over time, with a single payment at maturity that includes both the principal and accrued interest.

Interest-only (IO) issues are created by splitting mortgage-backed agency securities into different tranches. Investors in IOs receive payments solely from the interest portion of mortgage payments.

Principal-only (PO) issues are also derived from mortgage-backed agency securities. These bonds are sold at a discount and provide investors with principal payments only, without any interest.

Floating rates

Most agency bonds pay interest at a fixed rate, providing a predictable income stream over the bond’s life. However, some agency bonds, known as floaters, offer a variable interest rate. The rate on these bonds is adjusted periodically within specified limits based on a benchmark rate, such as LIBOR or the prime rate. This variability in interest payments can be advantageous if market rates rise, but it also introduces some uncertainty regarding future income.

What are the types of agency bonds?

Agency bonds are issued by two types of entities: Government Sponsored Enterprises (GSEs) and federal government agencies. The key distinction between the two lies in the level of government backing.

  • Federal agencies issue bonds that are explicitly guaranteed by the U.S. government. For example, the Government National Mortgage Association (GNMA), commonly known as Ginnie Mae, falls into this category.
  • GSEs, such as the Federal National Mortgage Association (FNMA), known as Fannie Mae, have an implicit government guarantee but are not officially backed by federal funds. While their obligations are considered low-risk, they do not carry the same explicit government guarantee as those issued by federal agencies.

Understanding GSE

Government Sponsored Enterprises (GSEs) are structured and operated as corporations, with some, like Farmer Mac, being publicly traded on the New York Stock Exchange, while others, such as the Federal Home Loan Bank, are not publicly listed. Despite their corporate status, GSEs maintain a special relationship with the government, which defines their functions, supervises their activities, and provides an implicit guarantee for their debt.

This implicit guarantee, while not as robust as the “full faith and credit” backing of U.S. Treasuries, is generally perceived as strong. Investors and financial markets often believe that a default by a GSE would be so damaging to the economy that the government would intervene with Treasury funds to prevent it. This belief is not unfounded, as the government previously stepped in to support the Farm Credit System during financial difficulties in the 1980s. Additionally, many GSEs have lines of credit with the Treasury that serve as a backup to ensure they can meet their obligations if necessary.

Understanding Federal Government agencies

Bonds issued by Federal Government agencies include:

  • The Federal Housing Administration (FHA)
  • The Small Business Administration (SBA)
  • The Government National Mortgage Association (GNMA or Ginnie Mae)

Like Treasury securities, most bonds issued by these federal agencies come with a federal government guarantee. However, bonds from federal agencies can have call risk due to their varying structural features. Additionally, while Treasury bonds generally offer higher liquidity, federal agency bonds might provide slightly higher interest rates to compensate for their lower liquidity compared to Treasuries.

Ginnie Mae (GNMA)

  • Type: Public Corporation
  • Credit Risk: Zero credit risk (backed by the full faith and credit of the U.S. government)
  • Risks: Subject to interest rate risk and prepayment risk

Government-Sponsored Enterprises (GSEs)

  • Structure: Operate as corporations
  • Public/Private Status: Some are publicly traded (e.g., Farmer Mac), while others are not (e.g., Federal Home Loan Bank)
  • Credit Risk: Generally viewed as low credit risk, with an implicit government guarantee

Fannie Mae & Freddie Mac

  • Specialization: Focus on mortgage-backed securities
  • Oversight: Under conservatorship of the Federal Housing Finance Agency (FHFA)

What is a Ginnie Mae?

Ginnie Mae is a public corporation within the U.S. Department of Housing and Urban Development (HUD). Unlike issuing bonds directly, Ginnie Mae guarantees mortgage-backed securities (MBS) to ensure that investors receive timely principal and interest payments. These MBS are formed from federally insured loans provided by the Federal Housing Administration (FHA) or federally guaranteed loans from the Department of Veterans Affairs (VA), and they are issued by private firms.

While Ginnie Mae securities are considered to have zero credit risk due to their government backing, they are still subject to interest rate risk—meaning their market prices fluctuate with changes in interest rates. They also face prepayment risk, where homeowners might pay off their mortgages early, disrupting the expected income stream. To compensate for these risks, Ginnie Mae securities generally offer higher yields than Treasury bonds but usually yield less than securities issued by Government-Sponsored Enterprises (GSEs). Besides traditional mortgage loans, Ginnie Mae also issues securities backed by home equity conversion mortgages (HECMs), commonly known as reverse mortgages, which are insured by the FHA.

FLOOD CONTROL

The Tennessee Valley Authority (TVA) is a federal government-owned public power utility. Unlike publicly traded companies or Government-Sponsored Enterprises (GSEs), TVA does not issue stock but can issue bonds to raise capital for its electricity generation projects. TVA bonds are fully backed by the revenue generated from selling the electricity produced. Some of these bonds are specifically targeted at individual investors.

What are Fannie and Freddie?

The relationship between the federal government and the Government-Sponsored Enterprises (GSEs) Fannie Mae and Freddie Mac is notably complex. Once influential and widely held, these giants of the residential mortgage market now face an uncertain future, and their situation has led to significant government involvement in mortgage lending.

Fannie Mae and Freddie Mac were established to increase homeownership accessibility by buying conforming mortgage loans from lenders, thereby providing them with cash to issue more loans. They would then bundle these loans into pass-through securities and sell them to raise additional funds for more loan purchases. However, when the real estate bubble burst, exacerbated by lenient lending standards, both GSEs faced severe financial difficulties due to rising mortgage delinquencies.

To stabilize the financial system and prevent further collapse, the federal government placed Fannie Mae and Freddie Mac into conservatorship. This action led to a dramatic decline in the value of their stocks and significant changes in their operations.

What are the advantages and disadvantages of agency bonds?

Investing in agency bonds can offer several benefits to investors. Many agency bonds provide interest that is exempt from federal and state taxes, though this does not apply to all agency bonds. For instance, agency bonds issued by entities like Farmer Mac, Freddie Mac, and Fannie Mae are taxable. Despite this, agency bonds generally offer higher yields compared to Treasuries, which are considered completely free of default risk.

These bonds play a crucial role in supporting public policy initiatives, such as lending to small businesses and agriculture, and enhancing liquidity in the housing market. Fannie Mae and Freddie Mac, for example, facilitate this by purchasing mortgages from lenders, converting them into securities, and reselling them to investors.

Investors should remain aware of the common risks associated with bonds, including interest rate risk, which affects all types of bonds, and credit risk, which is the chance that an issuer might fail to meet its payment obligations. Although agency bonds are not backed by the full faith of the government, they are perceived to have relatively low default risk.

Additionally, there are investment thresholds for agency bonds, such as Ginnie Mae bonds, which often require a minimum investment of $25,000, potentially limiting access for smaller investors. Furthermore, while capital gains or losses from the sale of agency bonds are subject to taxation, some agency bonds, like those from GSEs, are fully taxable based on local or state regulations.
