What caught my eye this week.
Five years flies by when your country is shooting itself in the foot , the world’s most powerful nation is led by a man-child , and a global pandemic  sinks and then super-charges your portfolio.
Even so, as the dust settled I was surprised to see that my NS&I Index-linked certificates are up for renewal again .
If you have no idea what these are, I don’t blame you.
NS&I’s coveted certificates  haven’t been available to new investors for almost a decade. Existing holders have been able to rollover what they have – but only for increasingly measly returns.
Roll over Beethoven
If I renew my certificates for another five years, then I will get a guaranteed return of 0.01% tax-free per annum, plus inflation1 .
The same return is also available on rollover into two-year and three-year certificates.
Given that I am sure NS&I is familiar with the time value of money , this unchanging return profile over two-to-five years tells us a lot about where the market appeal lies with these certificates.
It’s all about guaranteeing the preservation of the spending power of your money via the index-linking.
If I rollover for five years, say, my money will preserve its real2  value over that term. But the additional returns on top could be beaten by skipping a latte a year.
That’s a pathetic-looking reward for planning to lock your money away for five years3 .
And it gets worse!
In 2019, NS&I shifted the measure used to calculate the index-linking portion of the return. It now uses CPI instead of RPI. There are justifiable reasons for this, but as CPI has tended to run lower than RPI the net result for us investors is smaller gains over the years.
NS&I doesn’t hide  the impact of the shift, as illustrated by its table below (which uses 2019 inflation rates). It shows what you would get from a £1,000 investment under the two different inflation measures:
Historically low returns will very likely be even lower with CPI.
Merrily we roll along
So why do I plan to rollover these certificates again – and for the full five years?
Because even just getting your money back with that inflation-tracking uplift beats cash in the bank. Returns on savings are currently far lower.
And because if inflation should spike dramatically, these certificates provide some protection against that, too.
Meanwhile if inflation turns negative, the NS&I certificates don’t go down in value. You’d just get the 0.01% applied that year. So there’s an asymmetrical risk/reward on offer.
Finally, I’ll renew for the whole five years just in case they decide to scrap them in the next few years.
You’ve got to roll with it
The big potential downside to rolling over is, of course, the probable opportunity cost.
My self-managed portfolio more than doubled over the past five years. Needless to say that smashed the return from my NS&I certificates.
But good investing isn’t just about holding assets with the highest expected returns. We need diversification, and we need an emergency fund, too.
I wrote a lot  about my last rollover in 2016 that holds true today. Please check back for a full run through the attractions of these certificates.
The RPI element has gone since then, but that aside the certificates still look like unique asset class that we private investors are lucky to have access to.
Moreover they’re not issuing them any more. When it comes to the rollover it’s use it or lose it for those lucky enough to own them already.
Perhaps the biggest argument against rolling over for me, personally, is that unlike in 2016 I’m now running a big mortgage . I’d expect to earn a (slightly) higher return by cashing in my certificates and paying that down.
But then they’d be gone for me – and with them their unique diversification traits – and my overall investment posture would be less liquid (because I’d swap the semi-liquid certificates for a lower mortgage balance).
The cash value of my certificates could cover a couple of years of my mortgage payments, in a desperate pinch. Liquidity is valuable.
All told, my conclusion is much the same today as it was five years ago:
If these Index-linked certificates turn out to be the weakest performers over the next five years, then hurrah – because it will mean my vastly larger allocation to equities, for example, will have done better.
True, if I had a massive slug of these certificates then perhaps I’d need to think more carefully about how much money I wanted to commit to merely keeping up with inflation.
But like most people I only have a few percent in them, and as we’ve discussed they’re not making them anymore.
A solid hold, then. If only all investing decisions were this easy.
Let’s see where we are in 2026!
