What is a bond?

A bond is a loan to an entity (governments, corporations, municipalities, etc.) who promises to pay back the principal with interest at a specific future date.

Unlike stocks, corporate bondholders do not have ownership rights in the company, but they do have higher priority of repayment in the event of bankruptcy.

Most bonds are tied to a credit rating that describes their investment grade. Bonds classified as investment grade are higher-quality and generally offer a lower rate of interest. Non-investment grade bonds are expected to have greater default risk and therefore pay a higher rate of interest.

The types of risk associated with bonds include interest rate risk, credit/default risk, and prepayment risk. However, compared to equities and other riskier asset classes, fixed income investors typically are looking for a steady stream of income and prefer the relative safety of bonds.

Bond Characteristics

The characteristics highlighted below make each bond unique, and the variety of characteristics provide means for comparison.

🡆 A bond’s price is the amount of money the bond would cost, which is susceptible to changes in value over time as several factors determine whether it is attractive to potential buyers.

● If you buy a bond at issuance, the bond price is the par (face) value of the bond. The bondholder collects the stated interest payments, typically paid semi-annually, and principal amount at maturity.
● In secondary markets, bonds may be sold at par (face) value, or at a premium or discount to their par value. A bond that is trading above par is said to be trading at a premium, while a bond trading below par is trading at a discount. During periods when interest rates trend lower, a larger ratio of bonds will trade at a premium. When interest rates move higher, a larger proportion of bonds will trade at a discount.

🡆Par (Face) value is the amount the bond issuers promise to repay bondholders at the maturity date of the bond.

🡆 Maturity is the date when the par (face) value is paid back to investors and the issuing company’s obligation ends. The maturity of bonds is classified in three ways based on their time horizon:

● Short-term: describes bonds that mature within 1 to 3 years.
● Medium-term: describes bonds that mature over 10 years.
● Long-term: describes bonds that mature over longer periods of time, typically 10+ years.

🡆 Coupon (Interest) is the annual stated interest rate paid to bondholders. The coupon is normally paid out annually or semiannually.

● The coupon rate is calculated by dividing the sum of the annual payments by the par (face) value of the bond.

🡆 Yield-to-Maturity (YTM) is the estimated annualized rate of return an investor can expect on a bond if it were to be purchased today at the current price and held to maturity, assuming the issuer makes all their interest and principal payments (i.e., no defaults). It is a widely used measure to compare bonds.

🡆 Duration measures the sensitivity of a bond’s price to changes in interest rates. Bonds with higher duration have more interest rate sensitivity than bonds with low duration. Certain factors affect a bond’s duration, including time to maturity (the longer the maturity, the higher the duration), and the coupon rate (the higher the coupon rate, the lower the duration).

🡆 Credit Rating measures the bond issuer’s quality of credit and ability to pay back the principal and interest. Credit ratings are published by rating agencies.

● The most popular bond rating agencies that evaluate a company’s ability to repay its obligations are Standard & Poor’s, Moody’s Investors Service, and Fitch Ratings. Bonds with higher ratings generally offer lower coupon rates.

● Standard & Poor’s ratings range from AAA to AA- for high-grade issues, A+ to BBB- is investment grade. BB+ or below is speculative grade because credit risk is higher, making these bonds more vulnerable and subject to price volatility and, in some cases, default risk.

🡆 Credit spread is the difference in yield between a Treasury and different bond of the same maturity. Bonds with high credit spreads likely have low credit ratings. Bond credit spreads are often a good measurement of economic health.

● For the overall bond market, widening credit spreads suggest worsening economic conditions and higher overall risk. While narrowing credit spreads are a sign of improving economic conditions and lower overall risk.

Primary Bond Risks: Interest Rate and Default Risk

As with any type of investment, there are several risks associated with investing in bonds, including interest rate risk, default risk, inflation risk, call risk, reinvestment risk, credit risk, liquidity risk, market risk, and rating risk. Depending on the type of bond, it may not be sensitive to every type of risk. The two primary risks associated with bonds are interest rate and default risk.

Types of Bonds

🡆Treasuries (Bills, Notes, and Bonds): When the government borrows money, the Treasury Department sells securities to investors in the form of bills, notes, and bonds. Treasury securities are backed by the full faith and credit of the United States, which means their principal and interest payments are effectively assured by the government. Treasuries are offered in a wide range of maturities, are exempt from state and local taxes, and are usually very liquid.

● T-Bills have the shortest maturity terms from 4 weeks to 1 year. T-bills do not pay a coupon rate, rather they are issued at a discount and the par (face) value is paid fully at maturity. The difference between the price paid and the par value is considered interest.

● T-Notes mature between 2 and 10 years. Interest is paid semi-annually.

● T-Bonds have the longest maturity terms of 20 and 30 years. They typically offer the highest interest payments, paid semi-annually.

🡆 Treasury Inflation Protected Securities (TIPS) are a type of Treasury security whose par (face) value is indexed to inflation. Like traditional Treasuries, TIPS are backed by the full faith and credit of the US government.

● Prior to maturity, the par (face) value of a TIPS is adjusted up with inflation and down with deflation. Interest on a TIPS is paid semi-annually based on a fixed coupon rate and the adjusted par value.

● At maturity, investors receive the greater of either the increased (inflation-adjusted) price or the original par (face) value. TIPS investors do not receive less than the original par value in deflationary environment.

🡆 Corporate Bonds are bonds issued by a corporation to raise financing for a variety of reasons, including to fund ongoing operations, M&A activity, or to expand the business.

● Maturities can be short term (less than 3 years), medium term (4 to 10 years), or long term (more than 10 years). Longer-term bonds usually offer higher interest rates but may involve additional risks.

🡆 Municipal Bonds are debt securities issued by states, cities, counties, and other governmental entities to fund day-to-day obligations and to finance capital projects such as building schools, highways, or sewer systems.

● Municipal bonds can be tax advantageous for investors as they can potentially receive tax-exempt income at the federal, state, and local levels.

🡆 Agency Mortgage-Backed Securities (Agency MBS) are pools of securitized residential mortgage loans that are issued by US government agencies like Ginnie Mae or government-sponsored enterprises (GSEs) such as Fannie Mae or Freddie Mac.

● Ginnie Mae guarantees the timely payment of principal and interest on MBS backed by federally insured loans. Ginnie Mae MBS are backed by the full faith and credit of the United States government.

● Sponsored Enterprises (GSEs) Fannie Mae and Freddie Mac issue their own guarantees on timely interest and principal payments, but that assurance is not explicitly backed by the United States government. Before the Global Financial Crisis, investors assumed that the government implicitly backed Fannie and Freddie MBS securities. During 2008, both agencies were placed into government conservatorship and still remain there today. Investors still view GSE bonds as relatively low-risk and they typically offer yields higher than Treasuries and lower than Corporates.

🡆 Non-Agency Mortgage-Backed Securities (Non-Agency MBS) are mortgage-backed securities sponsored by private companies other than government sponsored enterprises.

🡆 High Yield Bonds are non-investment grade bonds from issuers that are considered to be at greater risk of not paying interest and/or returning principal at maturity. They are usually corporate bonds with a credit rating below BBB-.

🡆International Bonds are fixed income securities issued by a non-domestic entity. For United States investors, international bonds can either be dollar-denominated or issued in the local currency. International bonds can be subject to foreign exchange, country specific, and liquidity risk.

Fixed Income: Yield vs. Risk

Our objective with fixed income is to provide ballast, stability, and income to portfolios. Please remember that no strategy assures success or protects against loss.

● Ballast: bonds that have a low Aor negative correlation to equities. Ideally, the fixed income holdings are increasing when equity markets are declining. Typically, Treasuries or bonds with high credit ratings provide the most ballast.

● Stability: sought by investing in bonds with low price volatility no matter the macroeconomic environment. High quality short-term bonds have historically had lower volatility than most equity and other fixed income asset classes.

● Income: fixed income should ideally provide a predictable stream of income to portfolios. We generally try to optimize income without taking on unnecessary credit risk or volatility.

In fixed income investing, there is a clear risk/reward tradeoff. Bonds with lower yields typically provide more ballast (negative correlation to the S&P 500) and low risk. While bonds with higher yields generally have more credit risk and a high correlation to the equity market. The following chart shows the yield-to-maturity and risk (correlation to the S&P 500) of various Bloomberg bond indices:

Bond Prices Move Inversely to Interest Rates

The price of a bond in the United States will move inversely to Treasury interest rates (yields). In general, the Fed controls shorter term Treasury yields by setting the target federal funds rate, while the market controls long term interest rates as investor demand will vary based on future expectations of inflation and economic growth. A bond will be most sensitive to changes in either short or long-term Treasury yields depending on its time to maturity.

Bonds move inversely to interest rates because most bonds pay a fixed coupon rate, which typically corresponds to the current Treasury interest rate at issuance plus a spread to compensate the investor for the appropriate credit risk (i.e., more credit risk means a higher coupon rate). If interest rates rise after the bond is issued, the coupon rate would be less than those of newer bonds offered in the market. The older bond is now less attractive, which causes a drop in its price. If the price of the bond drops below par (face) value, the bond is trading at a discount. However, it is important to note that unless the bond issuer defaults, the discount is only temporary as the bond’s price will rise back toward par value as it gets closer to maturity.

Conversely, if interest rates fall after the bond is issued, the coupon rate would be higher than those of newer bonds offered in the market. The older bond is now more attractive, which causes its price to rise. If the price of the bond rises above par (face) value, the bond is trading at a premium. Unfortunately, this is also temporary as the bond’s price will decline back toward par as it gets closer to maturity.

Investors who wait on the sidelines for the “optimal” time to buy often miss significant rallies.

A $10,000 investment in 1980 would have increased to about $1,320,000 at the end of 2021. Note, this period includes over 10,500 trading days and assumes the individual stayed fully invested. If an investor missed only the 10 best days in the market, their total return would have been less than half. If an investor missed the 40 best days, their return would have been about one tenth.

To make things more difficult for market timers, the best days often occur during periods of severe market stress. Nine of the ten best days in the market over the last forty-two years occurred during either the Global Financial Crisis (2008-2009) or the Covid Pandemic (2020). Nervous or frustrated investors who threw in the towel would have missed the subsequent market rebound and devasted their portfolios.

During periods of market stress, it is impossible to know when the market bounce will occur, but we do know that missing the bounce has historically had a severe negative impact on total return.

US Bond Market: Annual Returns

The Bloomberg Barclays US Aggregate Bond index (Agg) acts as a proxy for the investment-grade bond market. Since inception of the index in 1976, the bond market has produced a total annualized return of +6.6%.

The bond market increased 89% of years with an average return of +8.1% and declined in 11% of years with an average drop of -4.1%.

The 10-Year Treasury yield is shown in the bottom of the chart. Bond prices move inversely to interest rates and credit spreads.

US Bond Market: Yield-to-Maturity

Yield to maturity is defined as the estimated annualized rate of return an investor can expect on a bond if purchased today and held to maturity, assuming the issuer makes all their interest and principal payments (i.e., no defaults).

The yield to maturity on the US Aggregate Bond index increased to 4.7% at the end of 2022, which was the highest level since 2008. In other words, future returns from the Agg bond index have not been this attractive in 14 years.

Correlation is a statistical measure of how closely two securities move in relation to each other. A high (positive) correlation implies the securities generally move in a similar direction, whereas a low (negative) correlation implies the securities generally move in opposite directions.

Asset allocation does not ensure a profit or protect against loss. There is no guarantee that a diversified portfolio will enhance overall returns or outperform a nondiversified portfolio.

Diversification does not protect against market risk. All investing involves risk which you should be prepared to bear.

The market value of corporate bonds will fluctuate, and if the bond is sold prior to maturity, the investor’s yield may differ from the advertised yield.

Mortgage backed securities are subject to credit, default, prepayment, extension, market and interest rate risk.

High yield/junk bonds (grade BB or below) are not investment grade securities, and are subject to higher interest rate, credit, and liquidity risks than those graded BBB and above. They generally should be part of a diversified portfolio for sophisticated investors.

Treasury inflation-protected securities (TIPS) help eliminate inflation risk to your portfolio as the principal is adjusted semiannually for inflation based on the Consumer Price Index – while providing a real rate of return guaranteed by the U.S. Government.
