Series I Savings Bonds (aka I bonds) have several features that can be particularly useful for middle-income pre-retirees and retirees building their retirement income portfolio. They offer high interest rates (currently yielding 7.12% per year), guarantees of principal and interest, and long-term liquidity (with a few caveats).

My last two posts described I bonds in more detail and shared three ideas for using I bonds to fund retirement expenses in the next five to 10 years, when it can be more problematic to use volatile investments like stocks.

This post shares three more ideas for using I bonds to develop your retirement income portfolio and support the type of spending that might take place over periods longer than 10 years.

Idea #1: Substitute I bonds for conventional bonds and bond funds

Most retirees don’t want to invest all their retirement savings in stocks or real estate, since stocks can decline in value, sometimes significantly if there’s a stock market crash. Retirees typically want to hold some investments in fixed income investments, such as individual bonds, bond mutual funds, and bond ETFs, because during a stock market crash, either they don’t decline or they decline much less than stocks.  However, these latter investments carry interest rate risk—if interest rates rise, the value of the investment drops, depending on the maturity of the bonds or bond funds.

I bonds are currently earning higher interest rates than most fixed income investments, and they don’t have the interest rate risk of other fixed income investments. The value of your investment will never decline. Pre-retirees and retirees could hold I bonds as a substitute for some of the bond investments they currently hold. The I bond investment could be one of the assets used to generate a regular retirement paycheck.

Another advantage: I bonds aren’t subject to state income taxes, so if you live in a high-tax state, such as New York or California, they can also help you save on taxes.

Idea #2: Develop a stock market buffer fund to address sequence of returns risk

If your retirement assets are significantly invested in stocks, then a serious risk you face is called “sequence of returns.” There’s been a lot written about this risk—do an internet search of the term if you’re not familiar with it. The bottom line is, when the stock market declines significantly (which is inevitable during a long retirement), you’re better off stopping withdrawals from stock investments until your stock investments rebound. But that means you’ll have less money to spend at that time.

One strategy to address sequence of returns risk would be to build a buffer fund of I bonds to draw upon for living expenses when you stop making withdrawals from your stock investments. I bonds would be particularly good for this purpose, since they’re liquid after one year of purchase, and your interest earnings aren’t subject to federal income taxes until you withdraw them.

Idea #3: Spending or gifts for education expenses

If you use an I bond to pay for qualified education expenses for yourself, your spouse, or a dependent, then the interest income isn’t subject to federal income taxes. This makes the interest totally free of income taxes, since states can’t tax interest income earned from I bonds.

I bonds can also be gifted to others, such as your adult children. Then that adult child could use the I bond to pay for the education of their own children, your grandchildren. The limits on the amounts you can purchase each year apply to each person, so in a calendar year, you could give each adult child I bonds in amounts up to $10,000, in addition to buying these amounts for yourself and your spouse if you’re married.

Here are links to the TreasuryDirect website that provide more information on using I bonds for education planning and FAQs.

Final thoughts

The features and caveats of I bonds as described in my prior two posts also apply to the ideas in this post. Please see those posts if you haven’t read them already to make sure you more fully understand their pros and cons.

One last thing to point out: I bonds don’t provide the opportunity for long-term growth, which stock and real estate investments can offer. These investments can help you to address the threat of inflation throughout your retirement. As a result, you might to consider I bonds in light of all your retirement investments.

If you’re thoughtful about your investments, however, Series I Savings Bonds are a good example of where Uncle Sam can really help you in your retirement!
