As riskier assets slip, I bonds have surged in popularity.

The bonds are backed by the federal government, the principal doesn't lose value, and the bonds earn monthly interest through two parts. The U.S. Department of Treasury announced in May that the variable component will pay a record 9.62% annual rate through October. The rate changes every six months.

If you are a person who is looking to get the highest yield possible without risk and you don't need this money for a long time, this is an investment that you should absolutely make.

A person can put up to $10,000 annually into I bonds through Treasury Direct. There are a few strategies available for those who want more.

These have turned out to be incredible investments during all the downturns that happened, according to Orman.

This is what to know.

Tax refunds

People who want to get a federal tax refund can choose to get up to $5,000 in paper I bonds.

It is possible to switch from a paper bond to a digital one.

Most people will not be able to take advantage of this option this year. To get a paper I bonds refund, you had to send in an IRS Form 8888 with your tax return.

Married couples and children

A married couple can put up to $10,000 in the investment annually or $15,000 each if they both choose to get tax refunds in paper I bonds.

The annual limit can be invested on behalf of each child. To make the purchase, the parent needs to create a Treasury Direct custodial account for the child.

Christopher Flis, a certified financial planner and founder of Resilient Asset Management in Memphis, Tennessee, said that money is a gift and must be used for the child's benefit.

The I bond purchasing limit can be extended by people who run businesses or have a living trust.

"There are several entities that are allowed to buy I bonds, including limited liability companies, corporations, and sole proprietors," said John Scherer, a CFP and founder of Trinity Financial Planning in Madison, Wisconsin.

Even if you are self-employed and file taxes on an IRS Schedule C as a small business, you can purchase up to $10,000 I bonds annually for that business. People can purchase an additional $10,000 in bonds through living trusts.

A married couple, each of whom own a business and have living trusts, could buy up to $60,000 in I bonds annually, as well as buying $5,000 per person in paper bonds, bringing their yearly total to $70,000. If that couple had two children, they would be able to purchase an additional $20,000 of bonds.

The administrative side

Purchasing bonds for so many different people can be difficult. Each person or entity that you purchase I bonds for will need to have a Treasury Direct account, so make sure to keep each login and password safe.

You have to keep track of when you can access the money when you buy I bonds. If you touch the money before five years, you will miss out on the last three months of interest that accumulated on your principle just before the sale.

Many people don't want to put tens of thousands of dollars into I bonds because they can't touch them for a year. According to Flis, bonds make sense in an emergency fund.

He thinks that some of your emergency fund should be in cash. If you have more money than you need in cash, it makes sense to put it in bonds to outrun inflation.

Flis said it was for the next tier of the emergency fund.
