Nationwide Building Society has announced details of a new range of Fixed-Rate ISA Bonds, which all offer a guaranteed interest rate for savers looking to take advantage of their annual tax-efficient allowance.

With effect from Friday 24 July 2009, Nationwide's new Fixed-Rate ISA Bond range will include a One-Year Fixed-Rate ISA bond paying up to 3.00 per cent gross/AER and a Two-Year Fixed-Rate ISA bond paying up to 3.50 per cent gross/AER.

It will also offer a three- and five-year product offering savers up to 3.75 per cent gross/AER and 4.50 per cent gross/AER, respectively. The Society accepts transfers-in on its full range of Fixed Rate ISA Bonds.

Rates on Nationwide's six-month Fixed Rate ISA Bond, full range of Fixed Rate Bonds and e-Bonds, one-year Guaranteed Savings Bond and three-year Stepped Rate Bond remain unchanged.  

The variable rate one year Tracker Bond continues to be available and is guaranteed to beat the Bank of England Base Rate by 2.05 per cent – 2.30 per cent depending on account balance.

Andy Hutchinson, head of savings at Nationwide, says, ‘The interest rate increase on a number of Nationwide's Fixed Rate ISA Bonds is good news for those savers looking for a guaranteed rate of return on their tax efficient savings.’

The previous range of one year, two year and three year Fixed Rate ISA Bonds will be withdrawn at 11.59pm on Thursday 23 July 2009. For more information, visit www.nationwide.co.uk.
