The new two Year Flexible Bond will pay 3.5% per cent AER on balances over £50,000 – the maximum investment is £1m.

The bond will pay 3.2% AER on balances below £50,000 – the minimum investment is £1.

According to Barclays, the bond allows three withdrawals of up to 10% (maximum 30%) of the initial deposit without notice or charges.

Barclays said customers taking out the flexible fixed rate bond can choose whether they want a regular monthly or annual income or grow their capital. New

Andy Gray, head of savings at Barclays said, "The vast majority of fixed rate bonds on the market do not offer any flexibility without charge or notice; so many customers are losing out on good rates of interest because they are reluctant to lock their money away in case they need it. Previously, customers have had to choose between the higher rates of fixed rate bonds or the flexibility of instant access accounts.

"The Barclays Flexible Bond will give savers the best of both worlds – a competitive fixed rate and the flexibility of having access to a good proportion of their savings when they need it," Gray said.
