How do savings bonds work?

Understanding How Savings Bonds Work

A savings bond is a government-backed, low-risk investment tool that is used to lend money to the government in return for interest over a specific period of time. The primary aim of this discourse is to provide a comprehensive explanation of how savings bonds work.

Defining Savings Bonds

Savings bonds are issued by governments as debt instruments to fund various public projects, such as infrastructure development. When you purchase a savings bond, you are essentially loaning money to the government. In return, the government promises to pay back the original amount (principal) along with a specified interest rate after a certain period, known as the maturity date.

Savings bonds are considered one of the safest investments since they are backed by the full faith and credit of the government. They are low-risk and somewhat conservative, providing steady, albeit modest, returns over time.

Types of Savings Bonds

In the United States, there are primarily two types of savings bonds available: Series I Bonds and Series EE Bonds.

Series I Bonds

Series I Bonds have an interest rate combined from a fixed rate, which remains the same throughout the life of the bond, and an inflation-adjusted rate, which is updated twice a year, in May and November. This protects the investor’s purchasing power by ensuring that their investment keeps pace with inflation.

Series EE Bonds

Series EE Bonds, on the other hand, have a fixed interest rate for the life of the bond. Meaning that the interest rate that you receive at the time of purchase remains consistent throughout the entire holding period.

Purchasing Savings Bonds

Savings bonds can be purchased directly from the government through the TreasuryDirect website. Paper savings bonds (which are no longer available to purchase but can still be redeemed if previously bought) can be bought in half of their face value, meaning you could purchase a $50 bond for $25. However, electronic savings bonds are purchased at face value, so a $50 bond costs $50.

Interest on Savings Bonds

Savings bonds accrue interest monthly and compound semiannually. Interest earned from savings bonds is exempt from state and local income taxes and federal taxes can be deferred until redemption or final maturity. This tax advantage makes savings bonds an attractive tool for long-term savings, particularly for funding education expenses.

Redeeming Savings Bonds

Savings bonds are designed to be held for the long term and have minimum holding periods before they can be redeemed (one year for both Series I and Series EE bonds). Although they reach face value in 20 years, electronic bonds can continue earning interest up to 30 years. Upon redemption, the bondholder will receive the original investment plus accrued interest.

However, if bonds are redeemed before 5 years, the last three months of interest will be forfeited as a penalty. It’s also worth noting that the value of the bond does not increase every month, but every six months. Therefore, it makes sense to wait until just after an interest-payment month to redeem the bond to maximize your return.

Risks and Limitations of Savings Bonds

While savings bonds are a highly secure investment, they are not without their disadvantages. The greatest downside is the relatively low rate of return compared to other types of investments. Furthermore, they lack liquidity, as cashing them in before five years incurs a penalty. Additionally, there is a limit on the number of bonds you can purchase in a calendar year, which is currently $10,000 per series per Social Security number.

Finally, the lack of secondary market means that you cannot sell the bonds to other investors; they can only be redeemed through the Treasury.


Savings bonds are an excellent investment for conservative investors seeking stability and a way to help fund governmental operations. They offer a way to earn a reliable, though modest, return on your investment while providing a number of tax advantages. However, like any investment, they should be carefully considered as part of a diversified portfolio that fits your investment objectives and risk tolerance.
