More than 80 per cent of instant access savings accounts do not offer savers an interest rate guarantee, Sainsbury's Finance has claimed.
New research by the supermarket suggests that only five per cent of instant access savings accounts on the market promise to pay a rate above the Bank of England Base Rate, while around a further five per cent of accounts offer a rate that is slightly below the Base Rate.
In a bid to help savers get more from their savings, Sainsbury's Easy Saver account pays a rate of 2.8 per cent Gross AER for the first 12 months, which is more than two per cent above the Base Rate.
Commenting, Helen Cook, head of savings at Sainsbury's Finance, urged consumers to shop around before opening a savings account.
"As well as looking at the headline rate of a savings account, you should also look to see what else is on offer. With Easy Saver, not only is there a rate promise for 12 months but in addition nectar card customers receive double nectar points on all their shopping at Sainsburys.
"There is a lot of volatility in the savings market at the moment and these can provide great peace of mind," she said.
