British Savings Bonds are fixed-term Issues of NS&I’s Guaranteed Growth Bonds and Guaranteed Income Bonds. They are available to new customers, and those with existing Bonds which are due to mature.
Today’s changes reflect changes in the wider market and will help NS&I to meet its Net Financing target while continuing to balance the interests of savers, taxpayers and the broader financial services sector.
