How to throw more money at an inflation hedge with this year-end hack

Sticker shock at the grocery store isn't going to disappear when the calendar flips into the new year. So if you can't beat inflation, you might as well hedge your bets.

And there's a year-end strategy that's been building buzz now that inflation-indexed savings bonds are paying an annualized rate of 7.12% for the six-month period after you buy the bonds. That rate is good for I Bonds bought from Nov. 1 through April 30, 2022.

The 7.12% annualized rate for the bonds is turning heads, given that many yields for a one-year certificate of deposit remain below 1%.

What's the year-end trick?

I Bonds are an option for those who want to park some money in a relatively low-risk spot for one year or more. If inflation rises in the months ahead, the rate could even adjust and go higher for a time.

The trick here focuses on a limit for how much you can invest in I Bonds in a given calendar year.

Each year, you only can buy up to $10,000 in electronic I Bonds or $20,000 per married couple. You buy savings bonds at www.TreasuryDirect.gov and hold them in an online account.

Once we move into 2022, an individual can buy another batch of I Bonds, up to $10,000 each or up to $20,000 per couple.

It means that a married couple could purchase up to $40,000 of I Bonds over a month or so, according to Dan Pederson, a certified financial planner and president of The Savings Bond Informer.

If you haven't bought any I Bonds in 2021, savers are effectively able to double the annual purchase limit within a short window by buying bonds before end of 2021 and again early in 2022.

What's the December deadline?

Even if you bought some I Bonds this year, as many people have, you could make sure to go up to that annual limit by Dec. 29.

A key tip: You can't wait until Dec. 31. That's a holiday this year for many banks and a federal holiday because Jan. 1 is a Saturday. Dec. 30 isn't going to cut it, either, to count as a 2021 purchase.

"The transaction would need to be processed this year before the end of this month," according to John Rizzo, senior spokesperson, public affairs for the U.S. Department of the Treasury.

He noted that it takes 24 hours for transactions to process because of the Automated Clearing House process.

"If a customer places a purchase this year on the deadline Dec. 29, it will post on Dec. 30," Rizzo said.

But if you'd buy on Dec. 30, the transaction won't post on Dec. 31 because that's a federal holiday.
