Leeds Building Society has launched a two-year fixed-rate bond that guarantees to pay a competitive 5.66% AER until January 31, 2009.

The product, which is for investments between GBP5,000 and GBP1 million, also has a monthly interest option which will pay 5.38% AER for those who require an income.

The annual interest can be credited to the account, another account with the society or be paid into a bank account elsewhere. The monthly interest, however, cannot be added to the account and must be transferred either to another building society or bank account, or to another account held with the society.

Karen Wint, head of marketing at Leeds Building Society, said: This straightforward postal bond offers customers the best two-year fixed-rate available. The best buy guaranteed AER rate of 5.66% combined with emergency access to funds at any time, subject to the loss of 90 days interest, cannot be found anywhere else in the market.
