Got my NS&I index-linked statement

From experience, I wouldn't trust NS&I to count a row of beans. Just as a matter of interest, I put my bond data into its process and it spits out a value which is not too different from the "today's valuation" my spreadsheet produces. I consider a predicted maturity figure which automatically converges on the real redemption figure to be, if you'll excuse the pun, of more interest.

I understand your misgivings with NS&I.

Fingers crossed you need to recalibrate your algorithm come next May to get an increased maturity value.

I'll try and keep the other thread I mentioned updated with progress up to maturity.

You don't, so here is an insight :)

One of the most shocking incidents was a discussion about how they describe the process by which the interest on ILCs is computed, in their own documentation. It started from my end at a middling level of understanding of arithmetic which, as I had to dumb it down and down ended up with the like of "you need to understand that the act of subtraction of two numbers and the act of division of two numbers are not the same process" (this in response to their statement that the division of two RPI values would be negative if the numerator was less than the denominator)

I'm sure that I will, the current situation is surely a pure artifact of brinkmanship in the oil market, and is already on the wane. As more and more real data replaces the extrapolation of the current figure this will occur - and, come next May, I'm pretty sure that we'll roll over.
