NS&I cuts rate on one-year British Savings Bonds to 4.04%, trailing market best buys
Treasury-backed provider reduces July rate of 4.18% to 4.04% on one-year fixed bonds, leaving savers able to find higher-paying one-year fixes elsewhere

National Savings & Investments has reduced the interest rate on its one-year Guaranteed Growth and Guaranteed Income Bonds — sold as British Savings Bonds — to 4.04%, further widening the gap between the Treasury-backed provider and the highest-paying one-year fixed deals on the market.
The new issues, open to new customers and to around 180,000 existing customers whose bonds are maturing, follow a July reissue that paid 4.18%. The latest cut means the NS&I offering now lags behind many challenger banks and specialist providers that have pushed one-year fixed rates higher this year.
Savers who shop for the best one-year fixed accounts can find rates above NS&I’s 4.04% level. Market comparison tables show top one-year fixed deals paying about 4.5% annually; for example, a Chetwood Bank one-year fixed deal at 4.5% would deliver an effective return of roughly £459.40 on a £10,000 lump sum over 12 months, assuming monthly compounding.
NS&I’s bonds are available both to new customers and to those rolling over maturing British Savings Bonds, and the institution has for years been used by savers seeking the security of a government-backed provider. The Treasury-backed status means NS&I can offer secure savings, but its rates often sit below those of smaller banks and building societies that use competitive deposit pricing to attract funds.
The rate cut comes against a backdrop of expectations among financial markets and forecasters that official interest rates could begin to fall later in the cycle, prompting some savers to lock in current rates. NS&I’s move reduces the incentive for savers to place new money there if their priority is short-term yield maximisation.
Industry commentators and comparison services note that the one-year British Savings Bonds have previously been priced below the best-buy tables. The latest change continues that pattern, meaning customers focused solely on return rather than government backing may prefer to compare products across the market before committing funds.
NS&I did not release a statement with the rate announcement setting out the rationale for the reduction. Analysts say providers adjust fixed-term offerings regularly in response to market funding needs and broader interest rate moves.

Savers considering a one-year fix are advised to check terms such as interest payment frequency, compounding, early access penalties, and whether rates quoted are gross or tax-free. The British Savings Bonds remain a government-guaranteed option but, for straightforward one-year returns, alternatives currently available in retail markets may offer higher nominal rates.
Market rates and product availability continue to change; comparison tools and adviser guidance can help consumers weigh the trade-off between security and yield when choosing where to place short-term savings.
