NS&I said the increases reflect changes in the wider savings market and will help it meet its Net Financing target while balancing the interests of savers, taxpayers and the broader financial services sector1. The Net Financing target for 2026-27 is £15 billion, plus or minus £4 billion1. This is Money reported that NS&I "struggles to hit a chunky net financing target of £15billion"2.
"We're pleased to be increasing interest rates across our 1, 2, 3, and 5-year British Savings Bonds, responding to changes in the wider market and giving savers the certainty of a guaranteed return for the duration of their chosen term."
Savers need a minimum investment of £500 and can invest a maximum of £1 million per person in each Issue1. Funds cannot be withdrawn early from these fixed-term accounts1. After the fixed term, savers can withdraw their cash or reinvest into a new term1. NS&I says all money invested with it is 100% secure and backed by HM Treasury1; This is Money reports the same Treasury backing2.
This is Money reported that the new Issues mark the first time these accounts have paid more than 5 per cent since January 20242. It also reported that the 1-year fix paid 4.04 per cent a year ago, the 2-year fix paid 4.25 per cent two years ago, and that NS&I paid 5.8 per cent on a 3-year fix in October 2023 and 1.65 per cent on a 5-year fix in October 20212. Those historical comparisons appear only in that report.
Why it matters for households
The rates apply to the new Issues on sale from 6 October 2026, so they affect savers opening these bonds from that date and those whose existing bonds mature and are reinvested into a new Issue1. Interest on Guaranteed Growth Bonds is calculated daily, added on each anniversary date and paid when the bond matures; the interest counts towards taxable income in the tax year the bond matures if the individual's threshold has been met1. Guaranteed Income Bonds pay interest monthly into a nominated bank account1. Unlike Premium Bonds prizes and Isas, these bonds are not exempt from tax, and This is Money noted that interest paid at maturity can use up the Personal Savings Allowance2. Money held in the bonds cannot be accessed before the term ends1.
What happens next
NS&I has not reported an end date for the new Issues. The previous rates applied from 18 August 20261. NS&I's Net Financing target for 2026-27 is £15 billion, plus or minus £4 billion1.
