Series I Bonds are a type of savings bond designed to provide investors with a low-risk investment option that keeps pace with inflation. Introduced in 1998, these bonds are backed by the full faith and credit of the U.S. government, ensuring their safety and reliability.

How do Series I Bonds Work?

Series I Bonds earn interest monthly, based on two components:

  1. Fixed Rate: A fixed rate set by the Treasury Department, which remains constant throughout the bond’s life.
  2. Inflation Rate: An inflation-indexed rate tied to the Consumer Price Index for Urban Consumer (CPI-U), adjusted semiannually.

The combined rate is recalculated every six months (May and November), ensuring the bond’s purchasing power keeps pace with inflation.
