How to Buy I Bonds: A Step-by-Step Guide - Uber Finance
Table of Contents

I Bonds have surged in popularity as a low-risk way to protect savings against inflation. But simply knowing how to purchase them isn’t enough. To make the most of this unique savings bond, you need to understand why I Bonds matter now, how they fit into different financial situations, and what limitations could affect your outcomes.

Why Buy I Bonds Now?

I Bonds are issued by the U.S. Department of the Treasury and combine two interest components:

  • Fixed rate – locked in at the time of purchase and stays the same for the life of the bond.
  • Inflation rate – adjusted every May and November based on the Consumer Price Index for All Urban Consumers (CPI-U).

This dual structure makes I Bonds especially appealing when inflation is high or uncertain. Unlike traditional bonds, their purchasing power isn’t easily eroded by rising prices. For households worried about volatile markets or shrinking savings accounts, I Bonds offer a safe, government-backed hedge.

How I Bonds Fit Different Financial Situations

I Bonds aren’t just for conservative savers. Depending on your goals, they can play several roles:

Retirement Hedge

I Bonds can complement other retirement assets by adding inflation-protected stability. While not a replacement for 401(k)s or IRAs, they’re a useful tool to balance out equity market risk.

College Savings

If redeemed for qualified higher education expenses, I Bond interest may be exempt from federal income tax. Parents saving for future tuition may benefit from combining I Bonds with 529 plans.

Emergency Reserves

Because I Bonds cannot be redeemed for the first 12 months, they aren’t for same-day liquidity. But after one year, they can supplement an emergency fund, offering better inflation protection than a traditional savings account.

The Traps and Limitations of I Bonds

Before you rush to TreasuryDirect, it’s important to know what I Bonds cannot do:

  • Annual purchase cap: You can only buy up to $10,000 in electronic I Bonds per Social Security number per year. Paper I Bonds (via tax refunds) allow an extra $5,000.
  • Early redemption penalty: Redeeming before five years forfeits the last three months of interest.
  • Market rate mismatch: If inflation slows, I Bond rates may lag behind market returns on other assets.
  • No IRA or brokerage purchase: I Bonds must be held through TreasuryDirect (or in paper form via refund), not in retirement or brokerage accounts.

Step-by-Step: Buying I Bonds

1. Set up a TreasuryDirect account

Go to TreasuryDirect.gov and create an account. You’ll need your Social Security number, email, bank routing and account number, and current address.

2. Decide how much to invest

Minimum: $25 (electronic). Maximum: $10,000 per calendar year per person, with an optional $5,000 paper purchase via tax refund. Couples can each purchase the annual maximum.

3. Purchase your bonds

Log in to TreasuryDirect, select BuyDirect, choose Series I Bonds, and enter your purchase amount. Bonds are issued electronically and can be tracked within your account.

4. Track and manage your investment

Monitor your bonds through your TreasuryDirect dashboard. You can see accrued interest, redemption eligibility, and your total holdings at any time.

FAQs

Can I Bonds lose value?

No. Even if inflation turns negative, the composite rate cannot go below zero. Your principal is always protected.

Can I buy I Bonds for my child?

Yes. Parents can open a TreasuryDirect custodial account linked to their own and purchase I Bonds in their child’s name, subject to the same annual limit.

Can I put I Bonds in an IRA?

No. I Bonds are not eligible for tax-advantaged retirement accounts. They must be purchased through TreasuryDirect or via tax refund.

What happens if inflation drops sharply?

The inflation-adjusted component will decrease at the next reset, but your fixed rate remains locked in. If inflation stays low, I Bonds may underperform other investments.

Conclusion

I Bonds can play a valuable role in protecting savings from inflation while offering government-backed security. But they aren’t a one-size-fits-all solution. By understanding the dual interest structure, knowing the purchase caps and penalties, and aligning I Bonds with your specific financial goals, you can decide whether they deserve a place in your portfolio. For many households, I Bonds are a useful building block — not the whole foundation.
