How to Buy I Bonds: A 2026 Guide

In recent years, the surge in inflation has rekindled interest in a government savings bond known as the Series I savings bond. These bonds, commonly referred to as I bonds, provide a secure investment option that shields savings from market volatility and the erosive effects of rising consumer prices. The interest rate on I bonds is directly linked to inflation, with the current rate standing at 4.26% until October 2026, including a fixed rate of 0.9% that can be locked in for up to 30 years.

Despite their attractive safety features and high interest rates, purchasing I bonds can be a cumbersome process. The only way to buy them is through the TreasuryDirect.gov website, as paper bonds were discontinued in 2025. Setting up an account on the Treasury’s website involves providing personal information, including your name, date of birth, address, tax identification number (Social Security number), and bank details. The website interface may feel outdated, and the entire process of purchasing I bonds can take around 20 minutes.

Once you have set up your TreasuryDirect account, you can proceed to buy digital I bonds. The process involves logging in to your account, selecting the “BuyDirect” tab, choosing “Series I” under the Savings Bonds section, and entering the desired purchase amount (minimum $25). There is an annual purchase limit of $10,000 per person, and you can schedule repeat purchases at your convenience.

I bonds are designed to protect the purchasing power of your money by offering a real rate of return above inflation. They have two interest rates – a variable rate based on inflation data and a fixed rate locked in at the time of purchase. The current fixed rate is 0.9%, which can be advantageous for long-term investors looking to outpace inflation.

While I bonds are considered one of the safest investments available, they come with certain limitations and caveats. For instance, there are restrictions on early withdrawals and annual purchase limits. Despite these drawbacks, I bonds are a popular choice for investors seeking a secure hedge against inflation and attractive tax benefits.

In conclusion, I bonds can be a beneficial investment option for those looking to safeguard their savings from inflation and earn a competitive interest rate. With the current rate of 4.26% and the opportunity to lock in a fixed rate of 0.9% for up to 30 years, now might be a favorable time to consider purchasing I bonds. Whether you are a seasoned investor or a novice looking to diversify your portfolio, I bonds offer a reliable and low-risk investment opportunity worth exploring.
