What is the interest rate on Series HH bonds issued in January of 1993? Tom's response January 93 HH bonds earned 4% for 10 years. In January 2003 they entered what the Treasury calls a new maturity period. At that time the rate for HH bonds entering new maturity periods was 1.5%. That's what they'll earn until they stop paying any interest at all in Jan 2013. My book, Savings Bond Alert, has a chapter on why 1.5% HH bonds are a bad choice for almost everyone. The book explains how to check out whether you should exchange your 1.5% HH bonds for regular savings bonds, which are the better after-tax deal for most people.
