Santander aims to 'turn the market on its head' by launching a 'revolutionary' Upfront Interest Bond.
The three year bond with a compound rate of 3.4% pays three years interest in advance, the first of its kind in the UK, the bank claims.
At 3.36% gross AER, the minimum £10,000 required to open the bond receives over £800 net interest within weeks of opening, a useful bonus for customers leading up to Christmas.
Santander's head of savings, Matt Hall, stated that anybody opening a bond by 20th November should be paid by the start of December.
"We have approached our new savings bond from a completely fresh angle", he added. "It is the first savings bond which pays interest upfront, instead of monthly or annual instalments. It is designed to give customers more control over their money at a time when we know they really need it."
"Obviously customers will be able to spend their upfront interest on whatever they like, maybe a holiday, Christmas shopping or even reinvest it to put it to work immediately."
Interest has to be paid into a Santander current account, the conditions state, and the original amount invested cannot be withdrawn until the bond has matured in December 2014.
Consumers may be intrigued by this innovative twist on savings returns at a time when levels of disposable income are relatively low, but that does not disguise the fact that the product is not the most competitive on the market in terms of interest. 12- and 18-month bonds recently released by the Yorkshire group are offering 3.4-3.5% gross interest per annum.
The advantage of Santander's product is that the early interest can be reinvested almost immediately, which allows it to deliver again with a little more effort on the saver's part.
Will you be tempted by the extra sum for extra saving or Christmas spending? Or, are the shorter term products still more efficient? Check out Which4U's savings accounts tables to check how Santander's 'revolutionary' bond compares.
