Birmingham Midshires, Post Office Savings and Yorkshire and Saffron building societies offer products where returns are linked to inflation.
The Post Office offers a five-year bond which pays a return of the retail price index plus 1.5 percentage points. So if RPI stands at 5pc a year from now, when interest is added to the account, you would get 6.5pc added to your money. The minimum investment is £500.
Yorkshire Building Society offers a similar return (RPI plus 1.5pc) although the minimum investment is £3,000. Saffron Building Society and Birmingham Midshire both pay a return equal to RPI. The Saffron Building Society is offering a six-year bond, while Birmingham Midshires has a three-year option, as well as the five-year bond for those that don't want to lock their money away for so long.
Savers should be aware that, if inflation falls, then so will the returns paid on these bonds.
