Does anyone know if there are any Instant access index linked saving accounts? I have been looking the only index lined account I can find is NSANDI but it is fixed for either 3 or 5 years, does that mean I can't withdraw my money without losing insterest?
A good question. I'd like to hear if anyone know of any index-linked savings accounts without tying up the money, too.
To address your NS&I question, with their Index-linked Certificates, interest is calculated month by month throughout the term, based, each month, upon the current RPI figure (published on the National Statistics website -- I was going to try to provide a link to the appropriate page, but their website seems to be having trouble -- maybe because Feb's CPI and RPI figures are due to be published today).
To discourage you from withdrawing early, if you withdraw your money within the first year, you will receive no interest (but you'll get all of your original investment back). After the first year, you will receive any interest accrued up to the point of withdrawal, but they increase the interest each year to encourage you to go the distance.
From memory (for the three-year one) during the first year, the interest rate is RPI + 1.1%; the second year is RPI + 1.3%; and the third year is RPI + 1.66%.
EDIT: The interest rates are for (as far as I know) the latest issue of the three-year Certificate. In theory, they could release a new issue (although they don't seem to be releasing new issues nearly as often as they used to), in which case, the 'bonus' rate of interest above the RPI could change.
