Savers are being urged to act quickly to secure interest rates as returns continue to decline month by month.

According to new research by Moneyfactscompare, savings interest rates are trending downward following the second Bank of England base rate cut this year.

Average one-year fixed bond rates have dropped to 4.24%, the lowest since June 2023, while longer-term fixed bonds now average 3.89%, their lowest point since March 2023.

However, some savings accounts are still paying rates of up to 8% AER.

Rachel Springall, finance expert at Moneyfacts, said: “Savers may be disappointed to see savings rates fall, but in positive news there has been a bit of life injected into the market as more providers enter the fray.

“Product choice now stands at its second highest level on our records and the variety of savings providers has reached a record high. These moves could instil a sense of optimism for savers who feel let down by the more familiar high street banks, as new challengers are more eager to attract deposits to fund their future lending.”

However, she noted: “The months ahead will be challenging for both providers to keep abreast of rate adjustments and for savers to move quickly to secure a new deal.”

According to Bank of England data, £252billion is currently sitting in UK current or savings accounts earning no interest whatsoever.

Ms Springall said: “It will be up to consumers to make time to move their hard-earned cash into an account which not just pays interest, but also provides a real return against the eroding impact of inflation, which is expected to stay above 2% for some time yet.”

Here is a list of the savings accounts offering the highest interest rates at the time of writing, according to Moneyfacts data.
