If you are looking for an inflation hedge that is absolutely guaranteed to protect your capital, you're out of luck. Now that NS&I has withdrawn its index-linked bond from the market, there isn't one.
If you want to be sure you get your capital back when you want it, you need to put it into one of the banks covered by Britain's deposit guarantee. But not one of them will allow you to maintain the real value of your savings: use the British banks and you guarantee that your wealth will be slowly eroded from here. So what do you do? National Grid thinks it has the answer.
Last week, with a knowing sense of what the investing classes are hankering after, it launched a new bond for the retail market, the returns from which are to be linked to the Retail Price Index (RPI). The bonds will pay a starting interest rate of 1.25%. That's not much, but the rate is paid half yearly and adjusted in line with the annual change in RPI eight months before each payment date along the way.

So, as the FT's Matthew Vincent notes, with the RPI at a (shocking) 5.2% today, the interest paid on the bonds first payment date in April next year will be half of 1.28%. But the key point and where the value in the bond lies is that over the ten years the capital value of the bond rises in line with the RPI.

So, in ten years' time, the money you get back will have the same inflation-adjusted value as the money you put in. That's not a bad deal. But what it absolutely is not is a replacement for the NS&I index-linked bond. Why?
First, for the very simple reason that the former was fully backed by the government and this is not. It isn't even a very highly rated bond. The credit agencies have given it a triple-B investment grade, but only just. It is also worth noting that if you have to sell the bond before the end of its ten-year term, you will have to do so in the open market: that means you could make a capital loss.
Finally, while you can put it in an Isa, it isn't tax free the returns will be taxed as income at your marginal rate. Still, what it does do is effectively guarantee a real return if you buy it at launch, put it in an Isa and hold it for ten years subject, of course, to the National Grid not going bust (the prospectus points to the "substantial risks" involved in this assumption).
In a lousy environment for inflation-shy investors, there aren't many other options that offer all this. So I don't expect National Grid to have too much trouble getting the issue away.
