Both electronic and paper versions of Series I savings bonds are purchased at face value and earn interest until they are redeemed or reach maturity. You must hold Series I bonds for at least 12 months before redeeming them. Series I savings bonds will continue to earn interest for up to 30 years. They will cease paying interest once they have matured.
Tomâs response. It depends on what you mean by maturity. Final maturity â when they stop earning interest â is 30 years after the issue date for all Series EE and I Savings Bonds, as well as for all Series E bonds that are still earning interest. For Series HH and H Savings Bonds, final maturity comes after 20 years. Series EE bonds also have an original maturity date â when they will be worth at least double your original investment. Series I, H, and HH bonds are all sold at face value and donât have this feature.
