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.
Interest rates increased slightly on May 1, and all EE savings bonds issued from May 2015 through October 2015 will earn 0.30% interest per year. The Treasury Department resets the rate for new EE savings bonds every six months. The rates have been very low for the past few years: less than 1% since November 2011, bottoming out at 0.10% for EE bonds issued from November 1, 2014, to April 30, 2015. EE savings bonds issued in May 2005 or later have a fixed interest rate for up to 30 years, based on the rate when you purchase the bond. (All EE bonds stop earning interest after 30 years.) The interest accrues monthly and is compounded twice a year. You can cash out anytime after holding the bond for a year, but youâll lose three monthsâ worth of interest if you redeem bonds before youâve owned them five years.
