Should you invest in a Pensioner Bond?

Are George Osborne's new Pensioner Bonds a good buy? They won't be launched until January 2015 and a lot could happen in that time. Including an interest rate rise (or two, even). Current estimates for the new NS&I bonds indicate 2.8% for one year and 4% for three years.

They're also limited to the first £10bn only. Should you, then, go for a Pensioner Bond? %VIRTUAL-SkimlinksPromo%
