I Bonds Rates Increase To 7.12%

I Bonds rates are expected to skyrocket when they adjust in November and it’s time to pay attention to them again.

Never heard of an I Bond before? Don’t worry, you’re not alone. They haven’t been popular for 20 years, but here’s why I Bonds will become a hot trend this year.

I Bonds Overview

It seems like inflation is everywhere these days. Soaring gas prices, sky-high construction costs, and expensive Uber rides. There’s a lot to complain about!

But complaining doesn’t get you anywhere. Instead, consider how to make money as inflation heats up with I Bonds.

What are I Bonds?

I Bonds, short for Series I Savings Bonds, are inflation-indexed U.S. savings bonds. It’s designed to protect the value of your cash from inflation.

I Bonds are a unique, very low-risk investment backed by the U.S. Treasury with a holding period from 12 months to 30 years. Think of Series I Bonds like bank certificate of deposits (CDs) that are liquid after 12 months.

You can’t redeem an I Bond within the first 12 months and if you cash it out before five years have passed, you’ll incur three months’ worth of interest.

It earns a composite rate, one rate is a fixed interest rate determined at the time you buy an I Bond and the other rate is a variable inflation rate that gets adjusted for inflation every six months. Combine the rates together and you get the composite rate (which is the total rate you earn interest on).

The variable rate essentially guarantees I Bond buyers that they’ll never lose the value of their money because of inflation.

I know, I know – this isn’t as thrilling as showing off your cryptocurrencies, but you’ll make a great deal more money now with Series I Bonds than parking your cash in a traditional savings account.

Why didn’t you recommend I Bonds before?

Because I Bonds haven’t been relevant for 20+ years. Inflation has been so low for the past couple of decades that there were better places to safely invest your cash for a higher return.

When I Bonds first came out in 1999, they were offering a whopping 7% composite rate. Since then, I Bonds rates have sunk to the bottom of the ocean floor with a fixed interest rate of 0% and a mediocre inflation rate.

However, the next inflation adjustment will be in November 2021, and that’s what everyone is excited about!

I Bond Rates for November 2021

New inflation numbers were just released at BLS.gov, which allows us to predict what I Bonds rates will be starting in November 2021.

I say predict because we can only calculate what the variable inflation rate will be, but not the fixed interest rate. Remember that I Bonds is a composite of the two rates.

New Variable Inflation Rate

Consumer Price Index for Urban Consumers, or CPI-U for short, was 274.310 in September 2021 compared to a CPI-U of 264.877 in March 2021.

274.3/264.9 = 1.0356, or a semi-annual increase of 3.56%. So…

Semiannual inflation rate = 3.56%
Fixed interest rate = currently 0% (determined separately)

Using the formula below, we can determine the minimum rate an I Bond buyer would get starting in November 2021:

Total rate = Fixed rate + 2 x Semiannual inflation rate + (Semiannual inflation rate X Fixed rate)
Total rate = 0.000 + 2 x 3.56 + (3.56 x 0)
Total rate = 7.12%

November 2021 I Bond Rates

If you buy in November 2021, you’ll get at least a 7.12% return plus whatever the new fixed interest rate will be for the first six months.

The fixed rate formula is unknown, but it’s linked to the yield of short-term Treasure Inflation-Protected Securities (TIPS). Short-term TIPS are near zero and therefore the fixed interest rate for I Bonds will likely stay at 0%.

Every six months, your I Bonds rates will adjust. The fixed rate will always stay at the same rate at the time of your purchase, while the variable rate will be based on inflation changes.

The fixed rate was as high as 3.60% back in May 2000. Those lucky I Bond holders would now earn an incredible 10.72% for the six months starting in November (3.60% fixed + 7.12% variable).

What if I buy I Bonds before the rate change?

If you buy I Bonds before the end of October 2021, you’ll be guaranteed a total rate of 3.54% for the next six months (based on the previous six months formula).

After that time period, your total rate will be at least 7.12% for the following six months (based on November 2021 rate adjustments).

In terms of the absolute worse-case scenario, where you:

  • buy the I Bond on October 31, 2021
  • sell the I Bond on October 1, 2022 (hold the I Bond for the minimum 12 months and incur a three-month interest penalty)

You’ll earn a 3.87% annualized return for an 11-month holding period.

You may be asking why 11 months and not 12 months. It’s because in this scenario, you bought the I Bond at the end of October. Even though you only held the I Bond for one day that month, you earn the entire months’ worth of interest.

It’s a near little trick to buy at the end of a month and gain the entire month’s interest.

Now let’s say you held that exact bond, but sold it in January 1, 2023 instead. In this case, you’d earn a 4.57% annualized return for a 14-month holding period.

In either situation, this is much higher than any available money market or CD rate.

Should I buy now or wait?

There’s no wrong choice as both the old and new rates are great compared to other equivalent alternatives. Find me another savings instrument that’s safe as a government bond and will offer more than a 3.87% return over 11 months.

You can’t.

I Bonds also have special benefits compared to a money market account or CD, like:

  • Exemption from state income taxes
  • Redemption for higher education is exempt from federal taxes
  • Tax deferral until bond redemption
  • Inflation protection

How to Buy I Bonds

You used to be able to buy savings bonds by simply walking into a bank, but that’s not the case anymore. The government no longer issue bonds in paper form (besides tax refunds – more on that below), you can only buy them in electronic form.

You can buy up to $10,000 in I Bonds each calendar year through an electronic TreasuryDirect account. Open an account at TreasuryDirect.gov to do so. The minimum purchase amount is $25.

The $10,000 limit is per person, not per household. In other words, a couple can buy a total of $20,000 in I Bonds per year. A family with children can buy another $10,000 per child as long as they have a Social Security Number.

Additionally, you can buy an extra $5,000 in paper I Bonds if you have a tax refund when you file your federal income tax return. Tax software like TurboTax will offer you this option if you’re due a refund. If you do your taxes by hand, you need to complete IRS Form 8888.

The minimum purchase amount is $50 when buying through a tax refund (Paper I Bonds come in denominations of $50, $100, $200, $500, and $1,000).

Most people don’t get a tax refund of $5,000 – at least not if you’re doing your taxes right.

In instances like this where you buy want more I Bonds and therefore want a bigger tax refund, a strategy you can use is purposely pay more in taxes throughout the year than you actually owe.

The Bottom Line

Personally, I plan on buying $20,000 worth of I Bonds before the end of October for myself and my significant other. I Bonds are ultra-safe investments and the rate is too good to pass up on.

The rest of my available money outside of investments is directed to chasing the best bank bonuses and earning interest in stablecoins (a less volatile cryptocurrency).

Make sure you have an adequate emergency fund parked at a high-yield savings account before exploring all the different ways to make your money work harder for you.

10 thoughts on “I Bonds Rates Increase To 7.12%”

    • TreasuryDirect (where you buy I Bonds from) is only meant for individuals to buy securities from the Treasury and manage them through an account within their website, so you can’t use it to buy Treasuries for an IRA.

      Even if you could, I don’t think you’d want to anyway, since you’re using after-tax money in a pre-tax account.

  1. I waited to10/29 to buy I bonds which was too late. Treasury couldn’t complete the transaction until 11/1which is the date of my bond, not 10/1 which I intended.

    • Thanks for the feedback that people may have to buy a few days earlier to ensure their purchase month isn’t delayed. That’s a bummer, but not so bad. You’ll still get 6 months worth of interest accrual at 7.12%. Then just hope that the next rate setting is competitive.

    • Yes, I’d max out on January 31 (and get a full month’s worth of interest in just one day) to lock in the 7.12% for the following six months!

    • That depends on what would you do with the money otherwise and what return vs risk that gives you. We know for sure if you buy the bonds now you’ll get a great rate overall for the next 12 months and then we’ll have to see what the inflation reading is next April.

    • Because you’ll get the 7.12% for the following six months AFTER your 3.54% rate is over in the first six months of owning the bond. That’s guaranteed whereas the rate after 7.12% is an unknown. No one can predict what inflation is in 2022.
