National Savings and Investments (NS&I) has announced a series of interest rate increases across its British Savings Bonds. This pushes returns for several fixed-term options above the 5% threshold for UK savers. The adjustments apply to both new customers and individuals holding accounts that are currently maturing.
The government-backed savings provider updated its Guaranteed Growth Bonds and Guaranteed Income Bonds to reflect shifts in the wider financial market. Under the revised pricing structure, growth bond rates have increased to 4.99% for a one-year term, 5.07% for two years, 5.10% for three years, and 5.17% for a five-year commitment.
Detailed Breakdown of New NS&I Rates
Savers can choose between Guaranteed Growth Bonds, which compound interest until maturity, and Guaranteed Income Bonds, which pay out regular monthly interest into a nominated bank account. The updated gross rates and Annual Equivalent Rates (AER) span multiple fixed durations:
- 1-year fixed term: Growth option at 4.99% AER (previously 4.82%)
- 2-year fixed term: Growth option at 5.07% AER (previously 4.81%)
- 3-year fixed term: Growth option at 5.10% AER (previously 4.83%)
- 5-year fixed term: Growth option at 5.17% AER (previously 4.85%)
The minimum investment required to open an account is £500. Individual depositors can invest up to £1 million per person in each bond issue. Funds placed into these fixed-term products cannot be withdrawn before the agreed term ends.
Treasury Backing and Market Position
A primary selling point for NS&I products is their 100% security guarantee. Commercial banks and building societies typically cap depositor protection at £120,000 per person under the Financial Services Compensation Scheme (FSCS). In contrast, NS&I is backed directly by HM Treasury, securing the entirety of larger deposits.
Andrew Westhead, NS&I Retail Director, explained that the adjustments balance the needs of savers, taxpayers, and the broader financial ecosystem while supporting the organization’s Net Financing targets.
“Today’s increases mean savers can now choose from improved fixed-term rates across our 1, 2, 3 and 5-year British Savings Bonds, with the certainty of knowing exactly what return they will receive over their chosen term. Alongside that certainty, customers continue to benefit from the reassurance that all money invested with NS&I is 100% secure and backed by HM Treasury,” said Andrew Westhead.
How NS&I Compares with the Wider Market
Financial experts note that while the rate hikes make NS&I products more competitive, they do not necessarily occupy the absolute top tier of the wider UK savings market. Rachel Springall, a finance expert at Moneyfactscompare.co.uk, observed that some challenger banks and smaller institutions offer slightly higher rates, though often with lower deposit protection limits.
Industry analysts also remind consumers to maintain adequate emergency funds in easy-access accounts, because fixed-term bonds lock away capital completely until maturity. With competition heating up across the UK savings sector, analysts advise consumers to act promptly if they intend to lock in current fixed rates. Providers frequently pull competitive products once deposit targets are reached.
