I-Bonds: Pros and Cons of Investing
During periods of high inflation like the one we’ve been living in, it can be a real challenge to find safe investments that will pay off without lagging the economy horribly. This is where investments like Series I savings bonds, better known as i-bonds, come in. However, there are some important things to learn before buying any, especially in terms of the pros and cons of these inflation-adjusted instruments.
What are I-bonds and how do they work?
Bonds are fixed-income investments that basically amount to a loan, usually either to a government entity or a company. Thus, they come with set terms governing the regular payments, interest, and length of the term.
Certain kinds of bonds are considered safe because you know exactly when and how much you’re going to get paid. Buying U.S. Treasuries is considered the safest for bonds because they’re backed by the full faith and credit of the U.S. government.
I-bonds are actually a form of bond issued by the U.S. Treasury, but they differ from the standard Treasury bonds. What makes I-bonds so unique compared to other types of bonds is that they provide a bit of protection against high inflation. In addition to paying a fixed interest rate that the Treasury sets, I-bonds also pay an inflation-adjusted variable rate determined by changes in the inflation rate as measured by the Consumer Price Index (CPI).
The Treasury Department sets the interest rates for its I-bonds two times a year, on the first business days in May and November. The rate of return on these bonds is actually a composite rate that combines their fixed and inflation-adjusted rates.
For example, the current I-bond rate for those issued between November 1 and April 30, 2025 will have an interest rate of 3.11%, which includes the rate set by the Treasury Department, 1.20%, plus the variable component based on the inflation rate.
The pros of investing in I-bonds
The headline benefit of I-bonds is the fact that their rates adjust for inflation, which is a massive advantage during periods of high inflation, although it becomes a disadvantage during periods of low inflation or deflation. Additionally, I-bonds tend to earn higher returns than most investments during such periods, including the average stock. In fact, I-bonds often outperform many of the highest-performing stocks as well during inflationary periods.
These Treasury-issued bonds generate high returns without all the risks of those other high-yielding investments because they’re backed by the U.S. government. Depending on the inflation rate, I-bonds can offer returns that are significantly higher than those of other low-risk investments like certificates of deposit (CDs) or high-yield savings accounts.
I-bonds are also attractive because investors bear almost no risk of losing their principal. The composite rate can never be less than 0%, even during deflationary periods when the inflation rate is negative. All interest is compounded, which also boosts your savings while your money is invested in I-bonds.
Finally, the income from I-bonds is sometimes exempt from tax for lower- and middle-income households that use it to pay for college tuition.
The cons of investing in I-bonds
Of course, no investment is perfect. There’s actually a limit on how much you can invest in I-bonds per year. The annual maximum in purchases is $10,000 worth of electronic I-bonds, although in some cases, you may be able to purchase an additional $5,000 worth of paper I-bonds using your tax refund.
The option to purchase paper I-bonds ends in 2024. Buying paper I-bonds with your income tax refund won’t be possible from January 2025. However, tax filers will still be able to buy I-bonds online, however.
Another disadvantage to I-bonds is the fact that you have to purchase them directly from the Treasury via the website, TreasuryDirect.gov, which means you can’t buy them through your brokerage with your other investments. Since I-bonds are sold by the government, there’s virtually no price or rate reporting, so you’ll have to carefully track your purchases on your own without the help of a brokerage.
Further, I-bonds must be held for at least a year, so you won’t be able to cash them out before a year is up if the rate plunges due to falling inflation. In fact, you’ll lose the last three months of interest if you redeem them before five years are up. Additionally, you won’t be paid until you redeem them, so your investment is locked up until then.
Finally, the variable inflation-related component of the rate on I-bonds can make them pay nothing during periods of little to no inflation.
Bottom line
While it may seem like there are a lot of negatives to holding I-bonds, the positives may significantly outweigh them during times of high inflation. Of course, whether or not I-bonds are right for you depends on multiple factors.
For example, they probably aren’t good for investors who need ready access to their funds because they’re tied up for at least a year. On the other hand, fixed-income investors who want a safe investment and think inflation will remain high may want to consider I-bonds. However, those who think inflation will moderate might want to consider other types of bonds that may pay higher rates.
It may be a good idea to discuss your savings and investing goals with a financial adviser to determine whether I-bonds might make a good addition to your current portfolio.
