As the maturity of a bond increases, its interest rate risk increases because longer-term bonds have greater price sensitivity (duration) to changes in interest rates. Longer maturities provide more time for rates to fluctuate, causing, for example, a 30-year bond's price to drop more than a 5-year bond's price when rates rise.
Generally, bonds with a shorter time to maturity carry a smaller interest rate risk compared to bonds with longer maturities. Long-term bonds imply a higher probability of interest rate changes. Therefore, they carry a higher interest rate risk.
Maturity can also affect interest rate risk. The longer the bond's maturity, the greater the risk that the bond's value could be impacted by changing interest rates prior to maturity, which may have a negative effect on the price of the bond.
Long-term bonds lock investors into a fixed interest rate for many years. If interest rates rise, investors are stuck earning a lower rate for a long time, making the bond less attractive. To compensate, the bond's price must fall more sharply. This is why long-term bonds are more sensitive to interest rate changes.
Investors who hold a bond to maturity (when it becomes due) get back the face value or "par value" of the bond. But investors who sell a bond before it matures may get a far different amount. For example, if interest rates have risen since the bond was purchased, the bondholder may have to sell at a discount—below par.
If a bond is held past its maturity, the federal government remains responsible for the debt. However, savings bonds that are held past their maturity date do not continue to earn interest and may actually lose value due to inflation.
Think of it as the finish line of your bond investment. It's the day your money comes back to you, ending the journey that began when you first bought the bond. Until that point, you're earning interest, but once the maturity date hits, it's time to collect your original amount and move on.
Interest rates directly affect bond prices. When interest rates rise, bond prices fall; when rates drop, bond prices rise. This relationship, known as interest rate risk, means that if you sell a bond before it matures, you may receive more or less than its face value depending on current rates.
Interest rate risk: Longer maturities mean that there's a greater chance for interest rates to change over the life of the bond, which affects the bond's price inversely. Price volatility: Longer-term bonds exhibit greater price fluctuations in response to interest rate movements compared to shorter-term bonds.
Interest rate risk is the potential for investment losses that can be triggered by a move upward in the prevailing rates for new debt instruments. If interest rates rise, for instance, the value of a bond or other fixed-income investment in the secondary market will decline.
Warren Buffett views bonds as a safe haven for cash, often recommending a 90/10 portfolio (90% S&P 500 index fund, 10% short-term government bonds) for average investors, while Berkshire Hathaway itself holds large amounts of U.S. Treasury bills for capital preservation and to earn competitive yields, especially when stocks are expensive. He favors short-term Treasuries (T-bills) due to low interest rate risk and high liquidity, using them to park cash while waiting for better stock opportunities, rather than as a primary growth engine.
Risk Considerations: The primary risks associated with corporate bonds are credit risk, interest rate risk, and market risk. In addition, some corporate bonds can be called for redemption by the issuer and have their principal repaid prior to the maturity date.
When interest rates rise, existing bonds paying lower interest rates become less attractive, typically causing their value to drop below their initial par value in the secondary market. (The regular interest payments remain unaffected.)
There are four types of structural interest rate risk. As defined in the Basel paper, the four risks are repricing (mismatch), yield curve, basis and optionality. Repricing or mismatch risk is created when fixed rate loans are funded by variable rate borrowings or when fixed rate deposits fund variable rate loans.
Key Indicators That Signal a Good Time to Buy Bonds
Interest Rates Are High or Peaking: When interest rates are high, bonds offer better returns. Also, buying near the peak of the rate cycle means bond prices may rise in the future.
Long-term bonds are more sensitive to interest rate changes than short-term bonds because of their longer duration. Since bond prices move inversely to interest rates, long-term bonds gain more when rates fall and lose more when they rise.
The time of maturity can be either short-term or long-term, and each duration comes with varying interest rates. Bonds with a longer term to maturity offer a higher interest rate than short-term bonds whose term to maturity is less than five years.
The yield curve – also called the term structure of interest rates – shows the yield on bonds over different terms to maturity.
Generally, the longer the maturity period of a bond, the higher the interest rate risk it carries. This is because long-term bonds lock in a fixed interest rate for a longer duration, making them more sensitive to changes in prevailing interest rates.
The protection offered by global bonds during periods of equity market downturns is nothing new. The long-term return correlation between equities and bonds has been broadly negative since the 1990s, meaning the asset classes generally move in opposite directions.
The only savings bonds that still earn interest are I bonds and some EE and HH bonds. For those, you must look at the issue date. EE and I bonds earn interest for 30 years from the issue date. HH bonds earn interest for 20 years from the issue date.
In general, when interest rates go down, bond prices go up. If this happens, you can make money by selling your bond before it matures. You'll get more than you paid for it, and you'll keep the interest you've made up until the time you sell it. Learn more about how interest rates affect bond prices .
For example, if you redeem a bond after 24 months, you'll only receive 21 months of interest. Depending on the interest rate of your bond and your own financial needs, it's generally beneficial to wait until full maturity to redeem them.
