I bonds


  • Inflation protection. One of the standout benefits of I bonds is the built-in inflation protection. Because part of the interest rate is adjusted semi-annually for inflation, it can help preserve the purchasing power of your investment. 
  • Can buy more I bonds than EE bonds. You can buy an additional $5,000 in paper bonds with your income tax refund.


  • Modest returns in low inflation. In periods of low inflation, the returns can be modest. Since the interest rate of I bonds is partly tied to inflation, low inflation can result in lower yields. 
  • Variable interest rates are a risk you can't discount when you buy an I bond, and it's not like you can just sell the bond when the rate falls. You're locked in for the first year. 

EE bonds


  • Guaranteed returns. One of the most attractive benefits of EE bonds is the guaranteed return. The U.S. Treasury pledges that these bonds will double in value if held for 20 years, translating to an effective interest rate of about 3.5% per year over that period. 
  • Stability: EE bonds offer a stable, predictable return, making them an excellent choice for conservative investors. 


  • Lack of inflation protection: The primary risk associated with EE bonds is the lack of protection against inflation. The fixed interest rate does not adjust for inflation, meaning that if inflation rises significantly, it can erode the purchasing power of the bond's return. 
  • Limited yield potential: EE bonds are a secure and low-risk investment, but they also come with lower returns than riskier investments such as stocks or mutual funds. Therefore, they may not be the best choice for those seeking higher returns and willing to accept higher risk. 

I bonds offer an inflation-protected return, ensuring your savings keep pace with rising costs. EE bonds, on the other hand, provide a fixed-interest rate for the life of the bond, offering a predictable return.

Benefits of both I bonds and EE bonds:

Tax advantages. Both I bonds and EE bonds offer tax advantages, including federal tax deferral until the bond is redeemed or reaches maturity, and exemption from state and local taxes. If used for educational expenses, they may be free from federal tax as well.

Safety: As a product of the U.S. Treasury, I and EE bonds come with a high degree of safety. They are backed by the full faith and credit of the U.S. government, which significantly lowers the risk of default.

Risks of both I bonds and EE bonds:

Early redemption penalties: While you can cash in I and EE bonds after one year, if you do so within the first five years, you'll lose the last three months' interest. This penalty can reduce your returns if you need to access your money early.

Limit on purchases: There's a limit on how much you can invest in I bonds and EE bonds each year.

Bottom line

I bonds, with their inflation-adjusted return, safeguard the investor's purchasing power during periods of high inflation. On the other hand, EE Bonds offer predictable returns with a fixed-interest rate and a guaranteed doubling of value if held for 20 years. Both share similar tax considerations, providing federal tax deferral and state and local tax exemption. 

The fundamental difference between them is the variable inflation interest rate offered by I bonds and the guaranteed 20 year doubling for EE bonds. I bond investors enjoy great flexibility. If inflation remains high, they can retain their bonds and profit. If inflation plummets, they can swap their securities for higher-paying conventional notes. Meanwhile, those who own EE bonds are stuck.

While I bonds can offer better protection in inflationary times, EE bonds offer stability even in volatile market conditions. Their relevance in your portfolio varies with market conditions and personal investment goals.
