After languishing as a somewhat obscure instrument since its introduction in 1998, U.S. Series I savings bonds (“I Bonds”) started drawing meaningful attention last year thanks in large part to inflationary pressures and media coverage highlighting its substantial yield for a nearly risk-free investment.

I felt an overview of I Bonds might be helpful for those who were either curious or perhaps remained unaware of their existence.

The bonds are available to U.S. Citizens, residents, and government employees and are subject to annual purchase limits. You can purchase up to $10,000 per person each calendar year electronically. Another $5,000 in paper I bonds can also be purchased each year using federal income tax refunds. There are ways to stretch the limits, for example, bonds can be purchased for spouses and children, and Treasury also allows the purchase for trusts and estates, which are essentially treated as separate individuals.
