We discussed here last month the first new issue of NSI index linked savings certificates for a year (issues 16-3year and 43-5year). They offered about 0.3% above RPI which was not very attractive.
I see that NSI are now offering issues number 18-3year and 45-5year. Issues 17 and 44 came and went so fast I never noticed them.
Issues 18 and 45 offer about 1% over RPI.
