Gap between highest-paying and lowest-paying 3-year fixed rate bond is 1.61%
- Locking in at lowest rates would cost up to £483 in lost interest over three years on a £10,000 deposit, enough for a weekend break in Europe
- Investec Save is highlighting the importance of shopping around on longer term fixed rate bonds
Savers locking in cash in longer term fixed rate accounts are being urged to take more care when shopping around, as new analysis shows the gap between the highest and lowest paying products can be as much as 1.6%.
On a £10,000 deposit the lost interest over a three-year term could be as much as £483, Investec Save says, which could pay for a weekend away in Europe.1
The average across all 3-year fixed rate accounts is currently 3.8% while the average for the top 10 paying accounts is 4.15%. That drops only marginally to 4.11% for the top 20 and to 4.01% for the top 50. Investec Save’s 3-year fixed rate account currently pays 4.16% AER.
However, for the bottom 10% of accounts, the average rate falls to 3.14% and for the bottom 25% it falls to 3.42%, Investec Save’s analysis of 3-year fixed rate accounts shows. There are currently 93 types available. The lowest 3-year fixed rate accounts pays just 2.61%.
David Hunt, Head of Deposits, Investec, said: “Making a quick decision on a three-year fixed rate will unfortunately have long-term implications for savers who choose lower-paying accounts.
“Shopping around and finding the most competitive rate is important for all savers but when it comes to locking money away for longer terms it is even more crucial.”
