Bonds allow governments and companies to sell some of their debt to investors. Bonds that offer a fixed interest rate are exposed to interest rate risk. If you buy bonds, it's best to know how interest rates could affect your investment. Inflation is the rising level of prices for goods and services. It can have two negative impacts on those who invest in bonds. One is obvious, while the other is more subtle. To invest wisely, you should learn about both. Key Takeaways Inflation is the rise in prices for goods and services. The Federal Reserve works to control inflation by raising short-term interest rates.The returns you will take home on your bonds are called the "nominal return." The nominal return is how inflation impacts your bond yields. Investors often weigh future purchasing power against whether or not something is a safe investment. In short, inflation makes interest rates go up. This, in turn, makes bond values go down, but the full picture is more complex. What Is Inflation? Inflation is the rise of prices for goods and services across all sectors in an economy. The effect of inflation is to decrease the value of money. When inflation rises, you are able to buy less with your money. Note Bond interest rates are also called "bond coupons." A bond with a fixed coupon rate will hold the same interest rate, no matter what happens in the market. Inflation is measured using the Consumer Price Index (CPI). The CPI tracks the change over time in the price of goods and services. Inflation and Federal Reserve Policy The Federal Reserve (the Fed) is the United States' central bank. It sets the country's monetary policy and manages inflation. When inflation rises, the Fed may choose to raise short-term interest rates. The goal is to reduce the demand for credit and help prevent the economy from overheating. When the Fed raises short-term rates—or when it is expected to do so in the future—intermediate and longer-term rates also tend to go up. Since bond prices and yields move in opposite directions, rising yields mean falling prices. That means a lower value for your fixed-income investment. Nominal Returns vs. Real Returns The second impact of inflation is less obvious. But, it can take a major bite out of your portfolio returns. This effect is the difference between the “nominal” return and the "real" return. The nominal return is what a bond or bond fund provides on paper. The real return is adjusted for inflation. Nominal Return - Inflation = Real Return To understand this concept, think of a shopping cart of food that you buy at the supermarket. If the items in the cart cost $100 this year, inflation of 3% means that the same group of items cost $103 a year later. Suppose that during that same year, you have a short-term bond fund with a yield of 1%. Over the year, the value of a $100 investment rises to $101 before taxes. On paper, you made 1%, but in real-world money, they actually lost $2 worth of purchasing power. The “real” return was –2%. The average rate of inflation in the United States since 1913 has been 3.2%. It is skewed somewhat by the high-inflation periods of World War I, World War II, and the 1970s, but it still means that investors needed to earn an average annual return of 3.2% just to stay even with inflation. However, with the pandemic's impact, the annual inflation rate for the United States jumped to 8.2% for the 12 months that ended September 2022. Keep in mind that inflation compounds each year, just like investment returns. But with inflation, the result is negative. From 1982 through the present, inflation has risen nearly 100% on a cumulative basis due to this compounding effect. As a result, you would have needed to see the value of your investments double during that time, just to keep up with inflation. Real Returns vs. Safety In some cases, investors are willing to trade a negative real return in exchange for safety. You may decide that preserving your principal is more important. If safety isn’t your top priority, be mindful of the impact of inflation. If your goal is to build a nest egg for the future, a bond or bond fund that pays 2% won't be enough. (Remember, your total return should be over 3.2%.) Instead, consider a diversified approach. Add medium- to higher-risk investments such as investment-grade corporate bonds, high-yield bonds, and equities. Many mutual fund companies offer real return funds that are designed to stay ahead of gradual inflation. One drawback to these bond funds is that their costs tend to be high. Both Vanguard and Fidelity offer products with lower fees than the industry average. The Bottom Line Inflation will always be a silent thief eating away at the value of your long-term investments. With some planning, you will be able to stay a step ahead of it. Frequently Asked Questions (FAQs) How do you hedge against inflation? To hedge, or protect, yourself against inflation, choose investment vehicles that are likely to outpace inflation. For example, Treasury Inflation-Protected Securities (TIPS) are a type of bond that adjusts the principal value of the bond based on inflation. Stocks typically keep pace with inflation, but they're also more volatile. Real estate is another investment that typically keeps pace with inflation. A good financial advisor can help you develop a strategy that meets your needs. Are savings bonds a good investment? Savings bonds typically have an interest rate that's in line with other safe savings vehicles like bank savings accounts. That means the interest rate is relatively low, but so is the default risk. They're a good investment if your goal is preserving your principal. Other options like CDs or fixed-interest annuities can also meet that goal, however, and they may pay a higher interest rate. If your goal is growth, other investment vehicles may be a better fit. Was this page helpful? Thanks for your feedback! Tell us why!
